[0037] Next, a description will be given of the specific processing performed by the specific processing unit 290 of the data processing device 12. In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."

[0038] The present invention is a system mounted on a child car seat that can be operated by a user using voice or text. Specific embodiments of this system will be described below.

[0039] First, the user sends a command to the car seat by voice or text. For example, the user commands "sing a song." This command is recognized by the terminal built into the car seat. The terminal analyzes the command and requests the necessary data from the server.

[0040] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[0041] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[0042] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[0043] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[0044] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[0045] Consider the following scenario as a concrete example: A family is traveling in a car and their child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system starts playing the song, allowing the child to enjoy the music. Next, if the child says, "I want you to read me a picture book," the system will display the specified picture book and read it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo, helping the child look forward to having fun at the zoo.

[0046] In this way, the system according to the present invention provides an environment in which children can remain interested even during long car journeys and parents can concentrate on driving safely.

[0109] Example 1

[0110] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."

[0111] Previous in-car entertainment systems were limited in the types of content and operation methods, making it difficult to keep children interested, especially during long car trips. There was also a need for an effective system that could quickly respond to user commands and provide a variety of content. Furthermore, there was a lack of a mechanism for recording user command history and system usage and using that information to improve services.

[0112] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.

[0113] In this invention, the server includes a means for a user to send commands by voice or text, a means for converting the voice into text using a voice recognition module, and a means for analyzing the commands using a text analysis module and sending a request to the server, thereby enabling rapid response to various user requests and providing a comfortable entertainment environment in the car.

[0114] "User" refers to the person who operates the system and sends commands using voice or text.

[0115] A "voice recognition module" refers to hardware or software that has the function of converting voice into text data.

[0116] "Text analysis module" refers to hardware or software that has the function of analyzing text data generated by the voice recognition module and generating instructions according to the content of the data.

[0117] A "server" refers to a computer system that communicates with a terminal via a network, retrieves specified content from a database, and transmits it to the terminal.

[0118] "Database" refers to a storage device in which the server stores content (music data, text data, voice data, etc.).

[0119] "Terminal" refers to a device through which a user sends instructions and plays or displays content received from a server.

[0120] "Log" refers to data that a server records, such as user activity and system usage.

[0121] "Content" refers to information and services (e.g., music data, picture book data, conversation data, etc.) provided by a server in response to a user's commands.

[0122] The "HTTPS protocol" refers to a communication protocol for securely transmitting data over the Internet.

[0123] The present invention is a system for providing entertainment for children in a car. A user can send commands to a terminal using voice or text, and the system responds by providing appropriate content.

[0124] First, when a user issues a voice command, such as "sing a song," the device's built-in microphone captures the voice. Next, the voice recognition module converts the voice into text using the Google Cloud Speech-to-Text API. The converted text is then analyzed by the text analysis module to understand the command.

[0125] The parsed command is sent as a request to the server, which retrieves the content corresponding to that command from its database. For example, if a song command is issued, the server searches for the corresponding music data in the database and sends it to the device. In this case, data is transferred securely using HTTPS as the communication protocol.

[0126] The terminal plays the received music data on the music player module, allowing the user to enjoy the music. Similarly, when a user issues a command to "read a picture book," the server retrieves the corresponding text data and audio data and displays and plays them on the terminal.

[0127] The server also logs user activity and system usage, allowing us to review system usage history and improve our services.

[0128] Consider the following scenarios as specific examples: If a child gets bored while traveling by car with a family, the parent can command "Sing a song" and the system will play the corresponding song, allowing the child to enjoy the music. Also, if the parent commands "Let's go to the zoo" before arriving, the server will retrieve activity information about the zoo and the device will display that information, allowing the child to enjoy knowing what to expect before arriving.

[0129] An example of a prompt sentence might be:

[0130] "Tell me more about your in-car entertainment system. The system recognizes voice commands, retrieves data from a server, and plays it."

[0131] "Describe a system that uses voice recognition to play songs and picture books to keep children entertained during long car trips."

[0132] As described above, it is possible to realize an in-car entertainment system that can quickly respond to a variety of user requests.

[0133] The flow of the identification process in the first embodiment will be described with reference to FIG.

[0134] Step 1: Receiving and Recognizing Voice Commands

[0135] Input: The user issues a voice command.

[0136] Specific operation: When the user issues a voice command such as "sing a song," the device's built-in microphone captures the audio.

[0137] Data processing: The device's voice recognition module converts the voice into text data using the Google Cloud Speech-to-Text API.

[0138] Output: The audio is output as text data saying "Sing a song."

[0139] Step 2: Parse the text data and send a request to the server

[0140] Input: The text data "Sing a song" generated in step 1.

[0141] Specific operation: The text analysis module of the terminal receives the text data and analyzes the content of the command.

[0142] Data processing: Through analysis, the user's intended command (in this case, "play music") is understood.

[0143] Output: A request specifying the "song ID" is generated and sent to the server.

[0144] Step 3: Retrieving content from the database

[0145] Input: The request sent from the device to the server (the specified "song ID").

[0146] What happens: The server receives the request and searches the database for the specified content.

[0147] Data processing: The server retrieves music data related to the corresponding "song ID" from a database (e.g., cloud storage).

[0148] Output: The retrieved music data is prepared by the server.

[0149] Step 4: Sending content from the server to the device

[0150] Input: Music data obtained in step 3.

[0151] Specific operation: The server sends music data to the terminal.

[0152] Data processing: Data is transferred securely using the HTTPS protocol.

[0153] Output: Music data is sent to the device.

[0154] Step 5: Playing content

[0155] Input: Music data sent to the device.

[0156] Specific operation: The music player module of the terminal plays the received music data.

[0157] Data processing: Decodes music data and converts it into an audio signal.

[0158] Output: The user can listen to the music.

[0159] Step 6: Logging user activity

[0160] Input: User commands and information about the content being played.

[0161] Specific operation: The server collects information such as the user's command, activity time, and song ID.

[0162] Data processing: The server compiles this information as log data and stores it in storage.

[0163] Output: Log data recorded as system usage history.

[0164] Through the above processing steps, appropriate content is provided in real time based on the user's commands, realizing an entertainment environment in the car.

[0165] (Application example 1)

[0166] Next, a description will be given of Application Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."

[0167] One problem with food delivery services is that children can get bored while waiting or eating. This requires parents and guardians to put in a lot of effort to keep their children from getting bored, which can make using delivery services stressful. Furthermore, boredom can affect children's behavior while eating.

[0168] The specific processing by the specific processing unit 290 of the data processing device 12 in the application example 1 is realized by the following means.

[0169] In this invention, the server includes: a means for a user to send commands by voice or text; a means for the server to retrieve specified content (songs, picture books, conversation data, children's entertainment, dining place information, activity information, etc.) from a database; a means for the terminal to play or display the retrieved content; a means for the server to log the user's activities; and a means for providing children's entertainment content while ordering a meal or while waiting. This allows children to enjoy their waiting time or while eating without getting bored, significantly reducing the burden on parents and guardians.

[0170] "User" means a person who utilizes the system to send commands by voice or text.

[0171] "Means for sending voice or text commands" means a method by which a user can send specific instructions to the system using voice or text input.

[0172] A "server" is a computer system that retrieves specified content from a database based on a user's command and transmits it to a terminal.

[0173] "Content" refers to items that the server retrieves from the database, such as songs, picture books, conversation data, children's entertainment, dining information, and activity information.

[0174] "Database" means a system that manages and stores content and provides data upon request.

[0175] A "terminal" is a device that allows a user to send commands by voice or text input and plays or displays content retrieved from a server.

[0176] "Means for playing or displaying" refers to the function of the terminal to play acquired content as audio or display it on the screen.

[0177] "Means for recording in a log" refers to a function that allows the server to save the details of user activities as recorded data.

[0178] "Means of providing entertainment content for children while ordering or waiting for a meal" refers to a method of providing content that children using a food delivery service can enjoy while ordering or waiting for their food to arrive.

[0179] "Entertainment content" refers to various entertainment elements that children can enjoy, such as songs, picture books, videos, and games.

[0180] The present invention aims to realize a system for providing entertainment for children in a food delivery service. A specific embodiment of this system will be described below.

[0181] System configuration

[0182] The system uses the following hardware and software:

[0183] 1. Hardware: Smartphone or tablet (iOS or Android)

[0184] 2. Software: Server (e.g., AWS, Google Cloud), speech recognition library (e.g., Google Cloud Speech-to-Text API), database (e.g., MySQL, MongoDB)

[0185] Program generation and processing flow

[0186] User command transmission and voice recognition

[0187] The user sends commands to the device by voice or text, such as "sing a song" or "read a picture book." This command is converted into text data using a speech recognition library.

[0188] Data retrieval by the server

[0189] The recognized text data is sent from the device to the server, which then analyzes the user's commands and retrieves the corresponding content (e.g., music data for a song or text and audio data for a picture book) from a database.

[0190] Playing and displaying content

[0191] The acquired content is sent from the server to the device, where it is played or displayed. For example, a song is played on a music player, and a picture book is displayed with text on the screen and audio played.

[0192] Activity logging

[0193] The server records user activity (e.g., time of command transmission, type of content played, playback time, etc.) in a log, allowing the system usage history to be checked later.

[0194] Providing entertainment for children

[0195] While ordering or waiting for a food delivery service, the user can issue a command to "provide entertainment content for children," and the device will play entertainment content such as cartoons and games, allowing children to have fun while waiting without getting bored.

[0196] Specific examples

[0197] For example, if a user orders food delivery and their child starts to get bored while they are waiting, the user can command the device to "sing a song to my child," and the system will start playing the specified song. Similarly, if the user commands the device to "tell me about zoo activities," the server will retrieve zoo-related activity information from the database and display it on the device.

[0198] Prompt Sentence Examples

[0199] "Please explain in detail how it works if you sing a song and send it as a voice command to the program."

[0200] "Please explain how requests for content retrieval are sent to the server."

[0201] "Please explain in detail how you would use voice recognition technology to ask questions and provide responses."

[0202] As described above, the system according to the present invention increases the convenience of food delivery services and provides an environment in which children can enjoy the waiting time.

[0203] The flow of the specific processing in the application example 1 will be described with reference to FIG.

[0204] Step 1:

[0205] The user sends commands to the terminal by voice or text. The input is voice or text data, and the output is the transmission of voice or text commands. Specifically, the user voice-inputs "sing a song."

[0206] Step 2:

[0207] The device uses voice recognition technology to convert voice commands into text data. The input is voice data and the output is text data. Specifically, the Google Cloud Speech-to-Text API is used to convert the voice data "Sing me a song" into the text data "Sing me a song."

[0208] Step 3:

[0209] The terminal sends the converted text data to the server. The input is text data, and the output is a request sent to the server. Specifically, the text data "Sing a song" is sent to the server.

[0210] Step 4:

[0211] The server analyzes the received text data and retrieves the corresponding content from the database. The input is text data, and the output is the retrieved content data. Specifically, the server analyzes the request "Sing a song" and retrieves the music data of the specified song from the database.

[0212] Step 5:

[0213] The server transmits the acquired content data to the terminal. The input is the content data, and the output is data transmission to the terminal. Specifically, the music data of the song is transmitted to the terminal.

[0214] Step 6:

[0215] The terminal receives the content data sent from the server and plays or displays it. The input is the content data, and the output is the playback or display of the content. Specifically, the terminal plays the music data of the song received on a music player.

[0216] Step 7:

[0217] The server records user activity in a log. The input is the user's command and content playback information, and the output is log data. Specifically, the log records the time the command was sent, the type of song played, and the playback time.

[0218] Step 8:

[0219] If the user sends a new command while ordering or waiting for food, the same process is repeated. The input is a new voice or text command, and the output is the provision of new content. Specifically, if the user commands, "Tell me about zoo activities," the server retrieves zoo activity information from the database and displays it on the device.

[0220] Furthermore, an emotion engine that estimates the user's emotion may be combined. That is, the identification processing unit 290 may estimate the user's emotion using the emotion identification model 59 and perform identification processing using the user's emotion.

[0221] The present invention is a system installed in a child car seat that allows the user to operate it using voice or text, recognizes the user's emotions, and provides appropriate content, allowing the user to have a comfortable and enjoyable time even during long car trips. Specific embodiments of this system are described below.

[0222] First, consider a scenario where a user sends a command to a car seat by voice or text. For example, the user commands, "Sing me a song." This command is recognized by a terminal built into the car seat. The terminal analyzes the command and requests the necessary data from a server.

[0223] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[0224] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[0225] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[0226] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[0227] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[0228] The present invention also incorporates an emotion engine. The emotion engine analyzes the user's voice data and facial expression data to recognize the user's emotional state. For example, if a child is in a bad mood, the emotion engine recognizes that emotion and is configured to provide more enjoyable content preferentially. Therefore, even if the user commands "sing a song," the server selects a song of an appropriate genre based on the emotional state recognized by the emotion engine. In this way, the user's emotional state can be monitored in real time and recorded in a log.

[0229] Consider the following scenario as a concrete example: A family is traveling in a car and their child starts to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo so that the child can look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine will recognize this state and prioritize providing comforting stories and music.

[0230] In this way, the system of the present invention adapts to the user's emotional state to provide an environment that keeps children interested even during long car trips and allows parents to concentrate on driving safely.

[0231] The processing flow will be explained below.

[0301] In this way, the system is designed to provide appropriate content based on the user's emotional state, allowing them to spend a comfortable and enjoyable time.

[0302] Example 2

[0303] Next, a description will be given of Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."

[0304] The challenge is to reduce boredom and discomfort for children during long car trips and provide an environment where parents can concentrate on driving safely.It is also necessary to provide content that suits the user's emotional state and maintain the child's interest.

[0305] The specific processing by the specific processing unit 290 of the data processing device 12 in the second embodiment is realized by the following means. In this invention, the server includes means for transmitting commands by the user's voice or text, means for the terminal to analyze the user's command using voice recognition technology and transmit the analysis result to the server, means for the server to acquire specified content (such as a song, a picture book, or conversation data) from a database, means for the server to transmit the acquired content to the terminal, means for the terminal to play or display the acquired content, and means for the server to record information such as the command reception time, song ID, and playback time in a log. This makes it possible to provide content that suits the user's emotional state, keep children interested even during long car trips, and provide an environment where parents can concentrate on driving safely.

[0306] "User" refers to a person who uses the system to send commands by voice or text.

[0307] "Terminal" refers to a device built into a child car seat that recognizes and analyzes user commands and plays or displays data.

[0308] "Speech recognition technology" refers to technology that converts the voice spoken by a user into text data.

[0309] A "server" refers to a computer system that retrieves content from a database based on instructions sent from a terminal and sends it to the terminal.

[0310] "Database" refers to a storage system in which content (songs, picture books, conversation data, etc.) is stored.

[0311] "Content" refers to information such as songs, picture books, conversation data, etc. provided to users.

[0312] "Log" refers to a file or data structure that records system usage (time of command reception, song ID, playback time, etc.).

[0313] "Emotional state" refers to the user's mood and emotions at that time, as analyzed from their voice and facial expressions.

[0314] An "emotion engine" refers to an algorithm that analyzes a user's voice and facial expression data to recognize their emotional state.

[0315] "Activities" refers to events and information related to a specified destination.

[0316] The present invention is a system installed in a child car seat that can be operated by the user using voice or text, recognizes the user's emotions, and provides appropriate content, allowing children to have a comfortable and enjoyable time even during long car trips.

[0317] First, the user sends a command to the car seat by voice or text. For example, "Sing a song." This command is recognized by a device built into the car seat. The hardware uses a voice recognition microphone, and the software uses the Google voice recognition API. The device converts the voice into text data, analyzes the command, and extracts the specific request.

[0318] Next, the device sends the parsed command to the server using an HTTP request. The server analyzes the received command and retrieves the content corresponding to the command from a database (e.g., MySQL). The retrieved content (e.g., music data) is then sent from the server to the device.

[0319] The device plays or displays the received content. Specifically, if it is music data, it will be played on the built-in music player, and if it is a picture book, it will display the text on the screen and play the audio data. This allows the user to enjoy the music or picture book.

[0320] The server also records information such as the time the request was received, the song ID, and the playback time as a log. For this purpose, Elasticsearch is used, making it possible to check the system usage history later.

[0321] Furthermore, the system is equipped with an emotion engine. The emotion engine acquires the user's voice and facial expression data through the device and sends it to the server. The server then uses the emotion engine (for example, Microsoft Azure Face API) to analyze the user's emotional state. Based on the analysis results, the server selects content appropriate to the user's emotional state and sends it to the device. For example, if the user commands "sing a song," the emotion engine will select a song from an appropriate genre based on the emotional state it recognizes.

[0322] Consider the following scenario as a concrete example: A family is traveling in a car and a child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands "Let's go to the zoo" just before arriving at their destination, the server retrieves information and activities related to the zoo from a database and displays that information on the device, allowing the child to look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine recognizes this state and prioritizes providing comforting stories and music.

[0323] An example of a prompt is as follows:

[0324] "Play this children's song"

[0325] "Read the picture book 'Little Red Riding Hood' aloud."

[0326] "Make plans to go to the zoo."

[0327] In this way, the system of the present invention adapts to the user's emotional state and provides appropriate content, thereby keeping children interested even during long car trips and providing an environment where parents can concentrate on driving safely.

[0328] The flow of the identification process in the second embodiment will be described with reference to FIG.

[0329] Processing Step Description

[0330] Step 1:

[0331] The user sends commands to the system by voice or text.

[0332] Input: User's voice or text command (e.g., "Sing me a song").

[0333] Output: Voice data captured by a voice recognition microphone or text data entered directly.

[0334] Specific action: The child says to the car seat, "Sing me a song."

[0335] Step 2:

[0336] The device uses voice recognition technology to analyze the user's commands, convert them into text, and send the results of the analysis to the server.

[0337] Input: Audio or text data.

[0338] Output: Text instruction data sent to the server (e.g. "Sing me a song").

[0339] Specific operation: The device uses the Google speech recognition API to convert the voice data into text data and sends the command "sing a song" to the server.

[0340] Step 3:

[0341] The server receives and parses the command and retrieves content from the database based on the command.

[0342] Input: Text instruction data received from the terminal (e.g., "Sing me a song").

[0343] Output: The specified content data (e.g. music data).

[0344] What happens: The server parses the command and retrieves the music data based on the corresponding song ID from the MySQL database.

[0345] Step 4:

[0346] The server transmits the acquired content data to the terminal.

[0347] Input: Content data retrieved from a database (e.g., music data).

[0348] Output: Content data sent to the device.

[0349] Specific operation: The server sends music data to the device using the HTTP protocol.

[0350] Step 5:

[0351] The device plays (or displays) the received content on a music player.

[0352] Input: Content data received from the server (e.g. music data).

[0353] Output: The music that is played or the text and images that are displayed.

[0354] What it does: The device's built-in music player plays music, which the child listens to.

[0355] Step 6:

[0356] The server logs information such as the time the command was received, the content ID, and the playback time.

[0357] Input: Received command data, content ID, playback time.

[0358] Output: Log data.

[0359] Specific operation: The server uses Elasticsearch to save the information "Song ID 123 started playing at 15:30:00 on 2023-10-12 and finished at 15:35:00" in the log.

[0360] Step 7:

[0361] The device captures the user's voice and facial expression data and sends it to the server, where it is analyzed using an emotion engine.

[0362] Input: User's voice and facial expression data.

[0363] Output: Emotion analysis results.

[0364] How it works: The device's camera and microphone capture the user's facial expressions and voice, and then send the data to the server, where it is analyzed using the emotion engine (Microsoft Azure Face API).

[0365] Step 8:

[0366] The server selects appropriate content based on the emotional state and sends it to the terminal.

[0367] Input: Sentiment analysis results.

[0368] Output: Content data appropriate to the user's emotional state.

[0369] Specific operation: Based on the results of the emotion analysis, the server retrieves uplifting songs and comforting stories from the database again and sends them to the device.

[0370] Through the above processing steps, the user can enjoy appropriate content through the child car seat and be provided with a comfortable experience optimized for their emotional state.

[0371] (Application example 2)

[0372] Next, a description will be given of Application Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the smart device 14 will be referred to as a "terminal."

[0373] Conventional child seat systems often fail to provide comfort or enjoyment for children during long car trips. In particular, they often fail to provide content tailored to a child's emotional state, leading to boredom or irritability. Furthermore, they offer limited information about destinations and activities, making it difficult for children to stay interested during the trip.

[0374] The specific processing by the specific processing unit 290 of the data processing device 12 in Application Example 2 is realized by the following means. In this invention, the server includes: means for the user to send commands by voice or text; means for the server to acquire specified content (music, story, dialogue data, etc.) from a database; means for the terminal to play or display the acquired content; means for the server to record the user's activities in a log; and means for analyzing the user's emotional state using emotion recognition technology and providing content accordingly. This makes it possible to provide appropriate content according to the user's emotional state, allowing children to spend a comfortable and enjoyable time even during long car trips.

[0375] A "means for users to send commands by voice or text" is a device or function that allows a user to send commands or requests to a system using voice or text input.

[0376] "Means for the server to retrieve specified content (music, story, dialogue data, etc.) from a database" refers to a method or device that allows the server to search for and retrieve specific content stored in a database.

[0377] The "means for the terminal to play or display the acquired content" refers to a device or function for the terminal to play or visually present the content received from the server.

[0378] "Means for the server to log user activity" refers to a mechanism that allows the server to record user operations and system operation status so that they can be checked later.

[0379] "Means for analyzing a user's emotional state using emotion recognition technology and providing content in accordance with that state" refers to technology or devices that grasp a user's emotional state by analyzing voice data and facial expression data, and select and provide content appropriate to that state.

[0380] This invention relates to a child car seat system for use in autonomous vehicles. In this system, a user sends commands using voice or text, a server retrieves specified content from a database, and a terminal plays or displays the retrieved content. Furthermore, emotion recognition technology is used to analyze the user's emotional state and provide content appropriate to the user's emotional state.

[0381] The system hardware configuration uses a smartphone or a head-mounted display. These devices include a microphone and speaker for audio input and output, and a display for video display. These devices communicate with a cloud server via the Internet.

[0382] The cloud server utilizes the following software and platforms:

[0383] Speech recognition technology: Google Cloud Speech-to-Text API

[0384] Emotion recognition technology: Microsoft Azure Emotion API

[0385] Content management and delivery: AWS Lambda, AWS RDS, and DynamoDB

[0386] Response generation: OpenAI's GPT-4

[0387] From the perspective of generating the system's programs, when a user sends a command via voice or text, the command is first analyzed locally via a smartphone or head-mounted display. The command is then sent to a cloud server, which retrieves appropriate content from a database based on the command. For example, if a user commands "sing a song," the server selects uplifting music content and sends it to the device, which then plays the music.

[0388] The process of analyzing the user's emotional state using emotion recognition technology also takes place on a cloud server. The user's voice and facial expression data are analyzed using Microsoft Azure's Emotion API, and the most appropriate content is selected based on that emotional state. For example, if a child is anxious, a reassuring story can be provided. For this reason, the emotion recognition engine can also monitor the user's emotional state in real time and record it in a log.

[0389] For example, if a child says, "Tell me about the zoo" while traveling in a family car, the cloud server retrieves information about the zoo from the database and sends it to the device. The device then uses a display device to present a map of the zoo and an animal quiz to the user.

[0390] Examples of prompts include:

[0391] Music Play Prompt: "Please play a happy song for the child who is feeling a bit down."

[0392] Picture Book Reading Prompt: "Read an engaging storybook to the child to keep their attention during the trip."

[0393] Informational prompt: "Provide interesting facts about the zoo and animals for the child's query about the zoo."

[0394] This allows children to have a comfortable and enjoyable time even during long car trips, while providing an environment where parents can concentrate on driving safely.

[0395] The flow of the specific processing in the application example 2 will be described with reference to FIG.

[0396] Step 1:

[0397] The user sends commands to the device by voice or text. The user's voice data or text data is collected by a smartphone or head-mounted display. The input is the user's voice command or text command, and the output is the voice data or text data.

[0398] Step 2:

[0399] The device converts voice data into text using voice recognition technology (Google Cloud Speech-to-Text API). The input is voice data and the output is text data. At this time, the device analyzes the voice command and sends it as text to the cloud server.

[0400] Step 3:

[0401] The server analyzes the received command text and retrieves the corresponding content (music, story, dialogue data, etc.) from the database. The input is the command text, and the output is the content data (music file, text file, audio file, etc.). The server searches the database for data based on the content ID corresponding to the command.

[0402] Step 4:

[0403] The server uses emotion recognition technology (Microsoft Azure's Emotion API) to analyze the user's voice data and facial expression data and evaluate the user's emotional state. The input is voice data and facial expression data, and the output is the user's emotional state (e.g., joy, sadness, excitement, etc.). Based on the results of this analysis, the server selects appropriate content.

[0404] Step 5:

[0405] The server selects appropriate content and sends it to the terminal. The input is the selected content data, and the output is the content data to be sent to the terminal. The server sends the data to the terminal through the network.

[0406] Step 6:

[0407] The device plays or displays the received content in an appropriate format. The input is the content data, and the output is a format that the user can view (e.g., playing music, displaying a story, etc.). The device provides the acquired content to the user.

[0408] Step 7:

[0409] The server logs all commands, responses, and emotional states. The input is data such as command text, content ID, and emotional state, and the output is records in a log file or database. The server stores this information for later review.

[0410] Step 8:

[0411] If the user issues an additional command, the process repeats, returning to step 1. The input is again the user's voice or text command, and the output is the provision of new content.

[0412] As a result, a system is realized that allows users to enjoy content comfortably and enjoyably even during long car trips.

[0413] The specific processing unit 290 transmits the result of the specific processing to the smart device 14. In the smart device 14, the control unit 46A causes the output device 40 to output the result of the specific processing. The microphone 38B acquires audio indicating a user input regarding the result of the specific processing. The control unit 46A transmits audio data indicating the user input acquired by the microphone 38B to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the audio data.

[0414] The data generation model 58 is a so-called generative AI (Artificial Intelligence). An example of the data generation model 58 is ChatGPT (Internet Search<URL: https: / / openai.com / blog / chatgpt> ), Gemini (Internet search <url: https: gemini.google.com ?hl="ja">) and other generation AIs. The data generation model 58 is obtained by performing deep learning on a neural network. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating voice, text data indicating text, and image data indicating an image is also input. The data generation model 58 performs inference on the input inference data in accordance with the instruction indicated by the prompt, and outputs the inference result in a data format such as voice data and text data. Here, inference refers to, for example, analysis, classification, prediction, and / or summarization.

[0415] In the above embodiment, an example in which the specific process is performed by the data processing device 12 has been given, but the technology of the present disclosure is not limited to this, and the specific process may be performed by the smart device 14.

[0416] [Second embodiment]

[0417] FIG. 3 shows an example of the configuration of a data processing system 210 according to the second embodiment.

[0418] 3, the data processing system 210 includes the data processing device 12 and smart glasses 214. An example of the data processing device 12 is a server.

[0419] The data processing device 12 includes a computer 22, a database 24, and a communication I / F 26. The computer 22 is an example of a "computer" according to the technology of the present disclosure. The computer 22 includes a processor 28, a RAM 30, and a storage 32. The processor 28, the RAM 30, and the storage 32 are connected to a bus 34. The database 24 and the communication I / F 26 are also connected to the bus 34. The communication I / F 26 is connected to a network 54. Examples of the network 54 include a WAN (Wide Area Network) and / or a LAN (Local Area Network).

[0420] The smart glasses 214 include a computer 36, a microphone 238, a speaker 240, a camera 42, and a communication I / F 44. The computer 36 includes a processor 46, a RAM 48, and a storage 50. The processor 46, the RAM 48, and the storage 50 are connected to a bus 52. The microphone 238, the speaker 240, and the camera 42 are also connected to the bus 52.

[0421] The microphone 238 receives instructions and the like from the user 20 by receiving voice uttered by the user 20. The microphone 238 captures the voice uttered by the user 20, converts the captured voice into audio data, and outputs it to the processor 46. The speaker 240 outputs audio in accordance with instructions from the processor 46.

[0422] Camera 42 is a small digital camera equipped with an optical system including a lens, aperture, and shutter, and an imaging element such as a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor, and captures images of the surroundings of user 20 (for example, an imaging range defined by an angle of view equivalent to the field of vision of a typical healthy person).

[0423] The communication I / F 44 is connected to a network 54. The communication I / Fs 44 and 26 control the exchange of various information between the processor 46 and the processor 28 via the network 54. The exchange of various information between the processor 46 and the processor 28 using the communication I / Fs 44 and 26 is carried out in a secure state.

[0424] Fig. 4 shows an example of the main functions of the data processing device 12 and the smart glasses 214. As shown in Fig. 4, in the data processing device 12, a specific process is performed by the processor 28. A specific process program 56 is stored in the storage 32.

[0425] The specific processing program 56 is an example of a "program" according to the technology of the present disclosure. The processor 28 reads the specific processing program 56 from the storage 32 and executes the read specific processing program 56 on the RAM 30. The specific processing is realized by the processor 28 operating as a specific processing unit 290 in accordance with the specific processing program 56 executed on the RAM 30.

[0426] The storage 32 stores a data generation model 58 and an emotion identification model 59. The data generation model 58 and the emotion identification model 59 are used by the identification processing unit 290.

[0427] In the smart glasses 214, the processor 46 performs the reception output process. A reception output program 60 is stored in the storage 50. The processor 46 reads the reception output program 60 from the storage 50 and executes the read reception output program 60 on the RAM 48. The reception output process is realized by the processor 46 operating as the control unit 46A in accordance with the reception output program 60 executed on the RAM 48.

[0428] Next, a description will be given of the identification process performed by the identification processing unit 290 of the data processing device 12. In the following description, the data processing device 12 will be referred to as the "server" and the smart glasses 214 will be referred to as the "terminal."

[0429] The present invention is a system mounted on a child car seat that can be operated by a user using voice or text. Specific embodiments of this system will be described below.

[0430] First, the user sends a command to the car seat by voice or text. For example, the user commands "sing a song." This command is recognized by the terminal built into the car seat. The terminal analyzes the command and requests the necessary data from the server.

[0431] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[0432] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[0433] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[0434] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[0435] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[0436] Consider the following scenario as a concrete example: A family is traveling in a car and their child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system starts playing the song, allowing the child to enjoy the music. Next, if the child says, "I want you to read me a picture book," the system will display the specified picture book and read it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo, helping the child look forward to having fun at the zoo.

[0437] In this way, the system according to the present invention provides an environment in which children can remain interested even during long car journeys and parents can concentrate on driving safely.

[0500] Example 1

[0501] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the smart glasses 214 will be referred to as a "terminal."

[0502] Previous in-car entertainment systems were limited in the types of content and operation methods, making it difficult to keep children interested, especially during long car trips. There was also a need for an effective system that could quickly respond to user commands and provide a variety of content. Furthermore, there was a lack of a mechanism for recording user command history and system usage and using that information to improve services.

[0503] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.

[0504] In this invention, the server includes a means for a user to send commands by voice or text, a means for converting the voice into text using a voice recognition module, and a means for analyzing the commands using a text analysis module and sending a request to the server, thereby enabling rapid response to various user requests and providing a comfortable entertainment environment in the car.

[0505] "User" refers to the person who operates the system and sends commands using voice or text.

[0506] A "voice recognition module" refers to hardware or software that has the function of converting voice into text data.

[0507] "Text analysis module" refers to hardware or software that has the function of analyzing text data generated by the voice recognition module and generating instructions according to the content of the data.

[0508] A "server" refers to a computer system that communicates with a terminal via a network, retrieves specified content from a database, and transmits it to the terminal.

[0509] "Database" refers to a storage device in which the server stores content (music data, text data, voice data, etc.).

[0510] "Terminal" refers to a device through which a user sends instructions and plays or displays content received from a server.

[0511] "Log" refers to data that a server records, such as user activity and system usage.

[0512] "Content" refers to information and services (e.g., music data, picture book data, conversation data, etc.) provided by a server in response to a user's commands.

[0513] The "HTTPS protocol" refers to a communication protocol for securely transmitting data over the Internet.

[0514] The present invention is a system for providing entertainment for children in a car. A user can send commands to a terminal using voice or text, and the system responds by providing appropriate content.

[0515] First, when a user issues a voice command, such as "sing a song," the device's built-in microphone captures the voice. Next, the voice recognition module converts the voice into text using the Google Cloud Speech-to-Text API. The converted text is then analyzed by the text analysis module to understand the command.

[0516] The parsed command is sent as a request to the server, which retrieves the content corresponding to that command from its database. For example, if a song command is issued, the server searches for the corresponding music data in the database and sends it to the device. In this case, data is transferred securely using HTTPS as the communication protocol.

[0517] The terminal plays the received music data on the music player module, allowing the user to enjoy the music. Similarly, when a user issues a command to "read a picture book," the server retrieves the corresponding text data and audio data and displays and plays them on the terminal.

[0518] The server also logs user activity and system usage, allowing us to review system usage history and improve our services.

[0519] Consider the following scenarios as specific examples: If a child gets bored while traveling by car with a family, the parent can command "Sing a song" and the system will play the corresponding song, allowing the child to enjoy the music. Also, if the parent commands "Let's go to the zoo" before arriving, the server will retrieve activity information about the zoo and the device will display that information, allowing the child to enjoy knowing what to expect before arriving.

[0520] An example of a prompt sentence might be:

[0521] "Tell me more about your in-car entertainment system. The system recognizes voice commands, retrieves data from a server, and plays it."

[0522] "Describe a system that uses voice recognition to play songs and picture books to keep children entertained during long car trips."

[0523] As described above, it is possible to realize an in-car entertainment system that can quickly respond to a variety of user requests.

[0524] The flow of the identification process in the first embodiment will be described with reference to FIG.

[0525] Step 1: Receiving and Recognizing Voice Commands

[0537] What happens: The server receives the request and searches the database for the specified content.

[0538] Data processing: The server retrieves music data related to the corresponding "song ID" from a database (e.g., cloud storage).

[0539] Output: The retrieved music data is prepared by the server.

[0540] Step 4: Sending content from the server to the device

[0541] Input: Music data obtained in step 3.

[0542] Specific operation: The server sends music data to the terminal.

[0543] Data processing: Data is transferred securely using the HTTPS protocol.

[0544] Output: Music data is sent to the device.

[0545] Step 5: Playing content

[0546] Input: Music data sent to the device.

[0547] Specific operation: The music player module of the terminal plays the received music data.

[0548] Data processing: Decodes music data and converts it into an audio signal.

[0549] Output: The user can listen to the music.

[0550] Step 6: Logging user activity

[0551] Input: User commands and information about the content being played.

[0552] Specific operation: The server collects information such as the user's command, activity time, and song ID.

[0553] Data processing: The server compiles this information as log data and stores it in storage.

[0554] Output: Log data recorded as system usage history.

[0555] Through the above processing steps, appropriate content is provided in real time based on the user's commands, realizing an entertainment environment in the car.

[0556] (Application example 1)

[0557] Next, a description will be given of Application Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the smart glasses 214 will be referred to as a "terminal."

[0558] One problem with food delivery services is that children can get bored while waiting or eating. This requires parents and guardians to put in a lot of effort to keep their children from getting bored, which can make using delivery services stressful. Furthermore, boredom can affect children's behavior while eating.

[0559] The specific processing by the specific processing unit 290 of the data processing device 12 in the application example 1 is realized by the following means.

[0560] In this invention, the server includes: a means for a user to send commands by voice or text; a means for the server to retrieve specified content (songs, picture books, conversation data, children's entertainment, dining place information, activity information, etc.) from a database; a means for the terminal to play or display the retrieved content; a means for the server to log the user's activities; and a means for providing children's entertainment content while ordering a meal or while waiting. This allows children to enjoy their waiting time or while eating without getting bored, significantly reducing the burden on parents and guardians.

[0561] "User" means a person who utilizes the system to send commands by voice or text.

[0562] "Means for sending voice or text commands" means a method by which a user can send specific instructions to the system using voice or text input.

[0563] A "server" is a computer system that retrieves specified content from a database based on a user's command and transmits it to a terminal.

[0564] "Content" refers to items that the server retrieves from the database, such as songs, picture books, conversation data, children's entertainment, dining information, and activity information.

[0565] "Database" means a system that manages and stores content and provides data upon request.

[0566] A "terminal" is a device that allows a user to send commands by voice or text input and plays or displays content retrieved from a server.

[0567] "Means for playing or displaying" refers to the function of the terminal to play acquired content as audio or display it on the screen.

[0568] "Means for recording in a log" refers to a function that allows the server to save the details of user activities as recorded data.

[0569] "Means of providing entertainment content for children while ordering or waiting for a meal" refers to a method of providing content that children using a food delivery service can enjoy while ordering or waiting for their food to arrive.

[0570] "Entertainment content" refers to various entertainment elements that children can enjoy, such as songs, picture books, videos, and games.

[0571] The present invention aims to realize a system for providing entertainment for children in a food delivery service. A specific embodiment of this system will be described below.

[0572] System configuration

[0573] The system uses the following hardware and software:

[0574] 1. Hardware: Smartphone or tablet (iOS or Android)

[0575] 2. Software: Server (e.g., AWS, Google Cloud), speech recognition library (e.g., Google Cloud Speech-to-Text API), database (e.g., MySQL, MongoDB)

[0576] Program generation and processing flow

[0577] User command transmission and voice recognition

[0578] The user sends commands to the device by voice or text, such as "sing a song" or "read a picture book." This command is converted into text data using a speech recognition library.

[0579] Data retrieval by the server

[0580] The recognized text data is sent from the device to the server, which then analyzes the user's commands and retrieves the corresponding content (e.g., music data for a song or text and audio data for a picture book) from a database.

[0581] Playing and displaying content

[0582] The acquired content is sent from the server to the device, where it is played or displayed. For example, a song is played on a music player, and a picture book is displayed with text on the screen and audio played.

[0583] Activity logging

[0584] The server records user activity (e.g., time of command transmission, type of content played, playback time, etc.) in a log, allowing the system usage history to be checked later.

[0585] Providing entertainment for children

[0586] While ordering or waiting for a food delivery service, the user can issue a command to "provide entertainment content for children," and the device will play entertainment content such as cartoons and games, allowing children to have fun while waiting without getting bored.

[0587] Specific examples

[0588] For example, if a user orders food delivery and their child starts to get bored while they are waiting, the user can command the device to "sing a song to my child," and the system will start playing the specified song. Similarly, if the user commands the device to "tell me about zoo activities," the server will retrieve zoo-related activity information from the database and display it on the device.

[0589] Prompt Sentence Examples

[0590] "Please explain in detail how it works if you sing a song and send it as a voice command to the program."

[0591] "Please explain how requests for content retrieval are sent to the server."

[0592] "Please explain in detail how you would use voice recognition technology to ask questions and provide responses."

[0593] As described above, the system according to the present invention increases the convenience of food delivery services and provides an environment in which children can enjoy the waiting time.

[0594] The flow of the specific processing in the application example 1 will be described with reference to FIG.

[0595] Step 1:

[0596] The user sends commands to the terminal by voice or text. The input is voice or text data, and the output is the transmission of voice or text commands. Specifically, the user voice-inputs "sing a song."

[0597] Step 2:

[0598] The device uses voice recognition technology to convert voice commands into text data. The input is voice data and the output is text data. Specifically, the Google Cloud Speech-to-Text API is used to convert the voice data "Sing me a song" into the text data "Sing me a song."

[0599] Step 3:

[0600] The terminal sends the converted text data to the server. The input is text data, and the output is a request sent to the server. Specifically, the text data "Sing a song" is sent to the server.

[0601] Step 4:

[0602] The server analyzes the received text data and retrieves the corresponding content from the database. The input is text data, and the output is the retrieved content data. Specifically, the server analyzes the request "Sing a song" and retrieves the music data of the specified song from the database.

[0603] Step 5:

[0604] The server transmits the acquired content data to the terminal. The input is the content data, and the output is data transmission to the terminal. Specifically, the music data of the song is transmitted to the terminal.

[0605] Step 6:

[0606] The terminal receives the content data sent from the server and plays or displays it. The input is the content data, and the output is the playback or display of the content. Specifically, the terminal plays the music data of the song received on a music player.

[0607] Step 7:

[0608] The server records user activity in a log. The input is the user's command and content playback information, and the output is log data. Specifically, the log records the time the command was sent, the type of song played, and the playback time.

[0609] Step 8:

[0610] If the user sends a new command while ordering or waiting for food, the same process is repeated. The input is a new voice or text command, and the output is the provision of new content. Specifically, if the user commands, "Tell me about zoo activities," the server retrieves zoo activity information from the database and displays it on the device.

[0611] Furthermore, an emotion engine that estimates the user's emotion may be further combined. That is, the identification processing unit 290 may estimate the user's emotion using the emotion identification model 59, and perform identification processing using the user's emotion.

[0612] The present invention is a system installed in a child car seat that allows the user to operate it using voice or text, recognizes the user's emotions, and provides appropriate content, allowing the user to have a comfortable and enjoyable time even during long car trips. Specific embodiments of this system are described below.

[0613] First, consider a scenario where a user sends a command to a car seat by voice or text. For example, the user commands, "Sing me a song." This command is recognized by a terminal built into the car seat. The terminal analyzes the command and requests the necessary data from a server.

[0614] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[0615] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[0616] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[0617] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[0618] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[0619] The present invention also incorporates an emotion engine. The emotion engine analyzes the user's voice data and facial expression data to recognize the user's emotional state. For example, if a child is in a bad mood, the emotion engine recognizes that emotion and is configured to provide more enjoyable content preferentially. Therefore, even if the user commands "sing a song," the server selects a song of an appropriate genre based on the emotional state recognized by the emotion engine. In this way, the user's emotional state can be monitored in real time and recorded in a log.

[0620] Consider the following scenario as a concrete example: A family is traveling in a car and their child starts to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo so that the child can look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine will recognize this state and prioritize providing comforting stories and music.

[0621] In this way, the system of the present invention adapts to the user's emotional state to provide an environment that keeps children interested even during long car trips and allows parents to concentrate on driving safely.

[0622] The processing flow will be explained below.

[0672] The response data received by the terminal is displayed on the display.

[0673] Step 8:

[0674] The server logs the questions, responses, processing time, and emotional state.

[0675] Processing that makes going out fun

[0676] Step 1:

[0677] The user sends a command to the terminal by voice or text, such as "Let's go to the zoo."

[0678] Step 2:

[0679] The terminal analyzes the user's commands using voice recognition technology and converts them into text data.

[0680] Step 3:

[0681] The device sends the analysis results to the server.

[0682] Step 4:

[0683] The server receives the user's voice data and facial expression data and analyzes the user's emotional state using an emotion engine.

[0684] Step 5:

[0685] The server retrieves destination-related activity information from a database based on the command and emotional state.

[0686] Step 6:

[0687] The server sends the activity information it finds to the device.

[0688] Step 7:

[0689] The terminal displays the received activity information on the display and notifies the user.

[0690] Step 8:

[0691] The server logs the time of receipt of the request, its destination, activity information, and emotional state.

[0692] In this way, the system is designed to provide appropriate content based on the user's emotional state, allowing them to spend a comfortable and enjoyable time.

[0693] Example 2

[0694] Next, a description will be given of Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the smart glasses 214 will be referred to as a "terminal."

[0695] The challenge is to reduce boredom and discomfort for children during long car trips and provide an environment where parents can concentrate on driving safely.It is also necessary to provide content that suits the user's emotional state and maintain the child's interest.

[0696] The specific processing by the specific processing unit 290 of the data processing device 12 in the second embodiment is realized by the following means. In this invention, the server includes means for transmitting commands by the user's voice or text, means for the terminal to analyze the user's command using voice recognition technology and transmit the analysis result to the server, means for the server to acquire specified content (such as a song, a picture book, or conversation data) from a database, means for the server to transmit the acquired content to the terminal, means for the terminal to play or display the acquired content, and means for the server to record information such as the command reception time, song ID, and playback time in a log. This makes it possible to provide content that suits the user's emotional state, keep children interested even during long car trips, and provide an environment where parents can concentrate on driving safely.

[0697] "User" refers to a person who uses the system to send commands by voice or text.

[0698] "Terminal" refers to a device built into a child car seat that recognizes and analyzes user commands and plays or displays data.

[0699] "Speech recognition technology" refers to technology that converts the voice spoken by a user into text data.

[0700] A "server" refers to a computer system that retrieves content from a database based on instructions sent from a terminal and sends it to the terminal.

[0701] "Database" refers to a storage system in which content (songs, picture books, conversation data, etc.) is stored.

[0702] "Content" refers to information such as songs, picture books, conversation data, etc. provided to users.

[0703] "Log" refers to a file or data structure that records system usage (time of command reception, song ID, playback time, etc.).

[0704] "Emotional state" refers to the user's mood and emotions at that time, as analyzed from their voice and facial expressions.

[0705] An "emotion engine" refers to an algorithm that analyzes a user's voice and facial expression data to recognize their emotional state.

[0706] "Activities" refers to events and information related to a specified destination.

[0707] The present invention is a system installed in a child car seat that can be operated by the user using voice or text, recognizes the user's emotions, and provides appropriate content, allowing children to have a comfortable and enjoyable time even during long car trips.

[0708] First, the user sends a command to the car seat by voice or text. For example, "Sing a song." This command is recognized by a device built into the car seat. The hardware uses a voice recognition microphone, and the software uses the Google voice recognition API. The device converts the voice into text data, analyzes the command, and extracts the specific request.

[0709] Next, the device sends the parsed command to the server using an HTTP request. The server analyzes the received command and retrieves the content corresponding to the command from a database (e.g., MySQL). The retrieved content (e.g., music data) is then sent from the server to the device.

[0710] The device plays or displays the received content. Specifically, if it is music data, it will be played on the built-in music player, and if it is a picture book, it will display the text on the screen and play the audio data. This allows the user to enjoy the music or picture book.

[0711] The server also records information such as the time the request was received, the song ID, and the playback time as a log. For this purpose, Elasticsearch is used, making it possible to check the system usage history later.

[0712] Furthermore, the system is equipped with an emotion engine. The emotion engine acquires the user's voice and facial expression data through the device and sends it to the server. The server then uses the emotion engine (for example, Microsoft Azure Face API) to analyze the user's emotional state. Based on the analysis results, the server selects content appropriate to the user's emotional state and sends it to the device. For example, if the user commands "sing a song," the emotion engine will select a song from an appropriate genre based on the emotional state it recognizes.

[0713] Consider the following scenario as a concrete example: A family is traveling in a car and a child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands "Let's go to the zoo" just before arriving at their destination, the server retrieves information and activities related to the zoo from a database and displays that information on the device, allowing the child to look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine recognizes this state and prioritizes providing comforting stories and music.

[0714] An example of a prompt is as follows:

[0715] "Play this children's song"

[0716] "Read the picture book 'Little Red Riding Hood' aloud."

[0717] "Make plans to go to the zoo."

[0718] In this way, the system of the present invention adapts to the user's emotional state and provides appropriate content, thereby keeping children interested even during long car trips and providing an environment where parents can concentrate on driving safely.

[0719] The flow of the identification process in the second embodiment will be described with reference to FIG.

[0720] Processing Step Description

[0721] Step 1:

[0722] The user sends commands to the system by voice or text.

[0723] Input: User's voice or text command (e.g., "Sing me a song").

[0724] Output: Voice data captured by a voice recognition microphone or text data entered directly.

[0725] Specific action: The child says to the car seat, "Sing me a song."

[0726] Step 2:

[0727] The device uses voice recognition technology to analyze the user's commands, convert them into text, and send the results of the analysis to the server.

[0728] Input: Audio or text data.

[0729] Output: Text instruction data sent to the server (e.g. "Sing me a song").

[0730] Specific operation: The device uses the Google speech recognition API to convert the voice data into text data and sends the command "sing a song" to the server.

[0731] Step 3:

[0732] The server receives and parses the command and retrieves content from the database based on the command.

[0733] Input: Text instruction data received from the terminal (e.g., "Sing me a song").

[0734] Output: The specified content data (e.g. music data).

[0735] What happens: The server parses the command and retrieves the music data based on the corresponding song ID from the MySQL database.

[0736] Step 4:

[0737] The server transmits the acquired content data to the terminal.

[0738] Input: Content data retrieved from a database (e.g., music data).

[0739] Output: Content data sent to the device.

[0740] Specific operation: The server sends music data to the device using the HTTP protocol.

[0741] Step 5:

[0742] The device plays (or displays) the received content on a music player.

[0743] Input: Content data received from the server (e.g. music data).

[0744] Output: The music that is played or the text and images that are displayed.

[0745] What it does: The device's built-in music player plays music, which the child listens to.

[0746] Step 6:

[0747] The server logs information such as the time the command was received, the content ID, and the playback time.

[0748] Input: Received command data, content ID, playback time.

[0749] Output: Log data.

[0750] Specific operation: The server uses Elasticsearch to save the information "Song ID 123 started playing at 15:30:00 on 2023-10-12 and finished at 15:35:00" in the log.

[0751] Step 7:

[0752] The device captures the user's voice and facial expression data and sends it to the server, where it is analyzed using an emotion engine.

[0753] Input: User's voice and facial expression data.

[0754] Output: Emotion analysis results.

[0755] How it works: The device's camera and microphone capture the user's facial expressions and voice, and then send the data to the server, where it is analyzed using the emotion engine (Microsoft Azure Face API).

[0756] Step 8:

[0757] The server selects appropriate content based on the emotional state and sends it to the terminal.

[0758] Input: Sentiment analysis results.

[0759] Output: Content data appropriate to the user's emotional state.

[0760] Specific operation: Based on the results of the emotion analysis, the server retrieves uplifting songs and comforting stories from the database again and sends them to the device.

[0761] Through the above processing steps, the user can enjoy appropriate content through the child car seat and be provided with a comfortable experience optimized for their emotional state.

[0762] (Application example 2)

[0763] Next, a description will be given of Application Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the smart glasses 214 will be referred to as a "terminal."

[0764] Conventional child seat systems often fail to provide comfort or enjoyment for children during long car trips. In particular, they often fail to provide content tailored to a child's emotional state, leading to boredom or irritability. Furthermore, they offer limited information about destinations and activities, making it difficult for children to stay interested during the trip.

[0765] The specific processing by the specific processing unit 290 of the data processing device 12 in Application Example 2 is realized by the following means. In this invention, the server includes: means for the user to send commands by voice or text; means for the server to acquire specified content (music, story, dialogue data, etc.) from a database; means for the terminal to play or display the acquired content; means for the server to record the user's activities in a log; and means for analyzing the user's emotional state using emotion recognition technology and providing content accordingly. This makes it possible to provide appropriate content according to the user's emotional state, allowing children to spend a comfortable and enjoyable time even during long car trips.

[0766] A "means for users to send commands by voice or text" is a device or function that allows a user to send commands or requests to a system using voice or text input.

[0767] "Means for the server to retrieve specified content (music, story, dialogue data, etc.) from a database" refers to a method or device that allows the server to search for and retrieve specific content stored in a database.

[0768] The "means for the terminal to play or display the acquired content" refers to a device or function for the terminal to play or visually present the content received from the server.

[0769] "Means for the server to log user activity" refers to a mechanism that allows the server to record user operations and system operation status so that they can be checked later.

[0770] "Means for analyzing a user's emotional state using emotion recognition technology and providing content in accordance with that state" refers to technology or devices that grasp a user's emotional state by analyzing voice data and facial expression data, and select and provide content appropriate to that state.

[0771] This invention relates to a child car seat system for use in autonomous vehicles. In this system, a user sends commands using voice or text, a server retrieves specified content from a database, and a terminal plays or displays the retrieved content. Furthermore, emotion recognition technology is used to analyze the user's emotional state and provide content appropriate to the user's emotional state.

[0772] The system hardware configuration uses a smartphone or a head-mounted display. These devices include a microphone and speaker for audio input and output, and a display for video display. These devices communicate with a cloud server via the Internet.

[0773] The cloud server utilizes the following software and platforms:

[0774] Speech recognition technology: Google Cloud Speech-to-Text API

[0775] Emotion recognition technology: Microsoft Azure Emotion API

[0776] Content management and delivery: AWS Lambda, AWS RDS, and DynamoDB

[0777] Response generation: OpenAI's GPT-4

[0778] From the perspective of generating the system's programs, when a user sends a command via voice or text, the command is first analyzed locally via a smartphone or head-mounted display. The command is then sent to a cloud server, which retrieves appropriate content from a database based on the command. For example, if a user commands "sing a song," the server selects uplifting music content and sends it to the device, which then plays the music.

[0779] The process of analyzing the user's emotional state using emotion recognition technology also takes place on a cloud server. The user's voice and facial expression data are analyzed using Microsoft Azure's Emotion API, and the most appropriate content is selected based on that emotional state. For example, if a child is anxious, a reassuring story can be provided. For this reason, the emotion recognition engine can also monitor the user's emotional state in real time and record it in a log.

[0780] For example, if a child says, "Tell me about the zoo" while traveling in a family car, the cloud server retrieves information about the zoo from the database and sends it to the device. The device then uses a display device to present a map of the zoo and an animal quiz to the user.

[0781] Examples of prompts include:

[0782] Music Play Prompt: "Please play a happy song for the child who is feeling a bit down."

[0783] Picture Book Reading Prompt: "Read an engaging storybook to the child to keep their attention during the trip."

[0784] Informational prompt: "Provide interesting facts about the zoo and animals for the child's query about the zoo."

[0785] This allows children to have a comfortable and enjoyable time even during long car trips, while providing an environment where parents can concentrate on driving safely.

[0786] The flow of the specific processing in the application example 2 will be described with reference to FIG.

[0787] Step 1:

[0788] The user sends commands to the device by voice or text. The user's voice data or text data is collected by a smartphone or head-mounted display. The input is the user's voice command or text command, and the output is the voice data or text data.

[0789] Step 2:

[0790] The device converts voice data into text using voice recognition technology (Google Cloud Speech-to-Text API). The input is voice data and the output is text data. At this time, the device analyzes the voice command and sends it as text to the cloud server.

[0791] Step 3:

[0792] The server analyzes the received command text and retrieves the corresponding content (music, story, dialogue data, etc.) from the database. The input is the command text, and the output is the content data (music file, text file, audio file, etc.). The server searches the database for data based on the content ID corresponding to the command.

[0793] Step 4:

[0794] The server uses emotion recognition technology (Microsoft Azure's Emotion API) to analyze the user's voice data and facial expression data and evaluate the user's emotional state. The input is voice data and facial expression data, and the output is the user's emotional state (e.g., joy, sadness, excitement, etc.). Based on the results of this analysis, the server selects appropriate content.

[0795] Step 5:

[0796] The server selects appropriate content and sends it to the terminal. The input is the selected content data, and the output is the content data to be sent to the terminal. The server sends the data to the terminal through the network.

[0797] Step 6:

[0798] The device plays or displays the received content in an appropriate format. The input is the content data, and the output is a format that the user can view (e.g., playing music, displaying a story, etc.). The device provides the acquired content to the user.

[0799] Step 7:

[0800] The server logs all commands, responses, and emotional states. The input is data such as command text, content ID, and emotional state, and the output is records in a log file or database. The server stores this information for later review.

[0801] Step 8:

[0802] If the user issues an additional command, the process repeats, returning to step 1. The input is again the user's voice or text command, and the output is the provision of new content.

[0803] As a result, a system is realized that allows users to enjoy content comfortably and enjoyably even during long car trips.

[0804] The specific processing unit 290 transmits the result of the specific processing to the smart glasses 214. In the smart glasses 214, the control unit 46A causes the speaker 240 to output the result of the specific processing. The microphone 238 acquires audio indicating a user input regarding the result of the specific processing. The control unit 46A transmits audio data indicating the user input acquired by the microphone 238 to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the audio data.

[0805] The data generation model 58 is a so-called generative AI (Artificial Intelligence). An example of the data generation model 58 is ChatGPT (Internet Search<URL: https: / / openai.com / blog / chatgpt> ), Gemini (Internet search <url: https: gemini.google.com ?hl="ja">) and other generation AIs. The data generation model 58 is obtained by performing deep learning on a neural network. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating voice, text data indicating text, and image data indicating an image is also input. The data generation model 58 performs inference on the input inference data in accordance with the instruction indicated by the prompt, and outputs the inference result in a data format such as voice data and text data. Here, inference refers to, for example, analysis, classification, prediction, and / or summarization.

[0806] In the above embodiment, an example in which the specific processing is performed by the data processing device 12 has been given, but the technology of the present disclosure is not limited to this, and the specific processing may be performed by the smart glasses 214.

[0807] [Third embodiment]

[0808] FIG. 5 shows an example of the configuration of a data processing system 310 according to the third embodiment.

The processor 28, the RAM 30, and the storage 32 are connected to a bus 34. The database 24 and the communication I / F 26 are also connected to the bus 34. The communication I / F 26 is connected to a network 54. Examples of the network 54 include a WAN (Wide Area Network) and / or a LAN (Local Area Network).

[0811] The headset type terminal 314 includes a computer 36, a microphone 238, a speaker 240, a camera 42, a communication I / F 44, and a display 343. The computer 36 includes a processor 46, a RAM 48, and a storage 50. The processor 46, the RAM 48, and the storage 50 are connected to a bus 52. The microphone 238, the speaker 240, the camera 42, and the display 343 are also connected to the bus 52.

[0812] The microphone 238 receives instructions and the like from the user 20 by receiving voice uttered by the user 20. The microphone 238 captures the voice uttered by the user 20, converts the captured voice into audio data, and outputs it to the processor 46. The speaker 240 outputs audio in accordance with instructions from the processor 46.

[0813] Camera 42 is a small digital camera equipped with an optical system including a lens, aperture, and shutter, and an imaging element such as a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor, and captures images of the surroundings of user 20 (for example, an imaging range defined by an angle of view equivalent to the field of vision of a typical healthy person).

[0814] The communication I / F 44 is connected to a network 54. The communication I / Fs 44 and 26 control the exchange of various information between the processor 46 and the processor 28 via the network 54. The exchange of various information between the processor 46 and the processor 28 using the communication I / Fs 44 and 26 is carried out in a secure state.

[0815] Fig. 6 shows an example of the main functions of the data processing device 12 and the headset type terminal 314. As shown in Fig. 6, in the data processing device 12, a specific process is performed by the processor 28. A specific process program 56 is stored in the storage 32.

[0816] The specific processing program 56 is an example of a "program" according to the technology of the present disclosure. The processor 28 reads the specific processing program 56 from the storage 32 and executes the read specific processing program 56 on the RAM 30. The specific processing is realized by the processor 28 operating as a specific processing unit 290 in accordance with the specific processing program 56 executed on the RAM 30.

[0817] The storage 32 stores a data generation model 58 and an emotion identification model 59. The data generation model 58 and the emotion identification model 59 are used by the identification processing unit 290.

[0818] In the headset type terminal 314, a reception output process is performed by the processor 46. A reception output program 60 is stored in the storage 50. The processor 46 reads the reception output program 60 from the storage 50 and executes the read reception output program 60 on the RAM 48. The reception output process is realized by the processor 46 operating as the control unit 46A in accordance with the reception output program 60 executed on the RAM 48.

[0819] Next, a description will be given of the identification process performed by the identification processing unit 290 of the data processing device 12. In the following description, the data processing device 12 will be referred to as the "server" and the headset type terminal 314 will be referred to as the "terminal."

[0820] The present invention is a system mounted on a child car seat that can be operated by a user using voice or text. Specific embodiments of this system will be described below.

[0821] First, the user sends a command to the car seat by voice or text. For example, the user commands "sing a song." This command is recognized by the terminal built into the car seat. The terminal analyzes the command and requests the necessary data from the server.

[0822] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[0823] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[0824] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[0825] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[0826] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[0827] Consider the following scenario as a concrete example: A family is traveling in a car and their child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system starts playing the song, allowing the child to enjoy the music. Next, if the child says, "I want you to read me a picture book," the system will display the specified picture book and read it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo, helping the child look forward to having fun at the zoo.

[0828] In this way, the system according to the present invention provides an environment in which children can remain interested even during long car journeys and parents can concentrate on driving safely.

[0891] Example 1

[0892] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the headset type terminal 314 will be referred to as a "terminal."

[0893] Previous in-car entertainment systems were limited in the types of content and operation methods, making it difficult to keep children interested, especially during long car trips. There was also a need for an effective system that could quickly respond to user commands and provide a variety of content. Furthermore, there was a lack of a mechanism for recording user command history and system usage and using that information to improve services.

[0894] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.

[0895] In this invention, the server includes a means for a user to send commands by voice or text, a means for converting the voice into text using a voice recognition module, and a means for analyzing the commands using a text analysis module and sending a request to the server, thereby enabling rapid response to various user requests and providing a comfortable entertainment environment in the car.

[0896] "User" refers to the person who operates the system and sends commands using voice or text.

[0897] A "voice recognition module" refers to hardware or software that has the function of converting voice into text data.

[0898] "Text analysis module" refers to hardware or software that has the function of analyzing text data generated by the voice recognition module and generating instructions according to the content of the data.

[0899] A "server" refers to a computer system that communicates with a terminal via a network, retrieves specified content from a database, and transmits it to the terminal.

[0900] "Database" refers to a storage device in which the server stores content (music data, text data, voice data, etc.).

[0901] "Terminal" refers to a device through which a user sends instructions and plays or displays content received from a server.

[0902] "Log" refers to data that a server records, such as user activity and system usage.

[0903] "Content" refers to information and services (e.g., music data, picture book data, conversation data, etc.) provided by a server in response to a user's commands.

[0904] The "HTTPS protocol" refers to a communication protocol for securely transmitting data over the Internet.

[0905] The present invention is a system for providing entertainment for children in a car. A user can send commands to a terminal using voice or text, and the system responds by providing appropriate content.

[0906] First, when a user issues a voice command, such as "sing a song," the device's built-in microphone captures the voice. Next, the voice recognition module converts the voice into text using the Google Cloud Speech-to-Text API. The converted text is then analyzed by the text analysis module to understand the command.

[0907] The parsed command is sent as a request to the server, which retrieves the content corresponding to that command from its database. For example, if a song command is issued, the server searches for the corresponding music data in the database and sends it to the device. In this case, data is transferred securely using HTTPS as the communication protocol.

[0908] The terminal plays the received music data on the music player module, allowing the user to enjoy the music. Similarly, when a user issues a command to "read a picture book," the server retrieves the corresponding text data and audio data and displays and plays them on the terminal.

[0909] The server also logs user activity and system usage, allowing us to review system usage history and improve our services.

[0910] Consider the following scenarios as specific examples: If a child gets bored while traveling by car with a family, the parent can command "Sing a song" and the system will play the corresponding song, allowing the child to enjoy the music. Also, if the parent commands "Let's go to the zoo" before arriving, the server will retrieve activity information about the zoo and the device will display that information, allowing the child to enjoy knowing what to expect before arriving.

[0911] An example of a prompt sentence might be:

[0912] "Tell me more about your in-car entertainment system. The system recognizes voice commands, retrieves data from a server, and plays it."

[0913] "Describe a system that uses voice recognition to play songs and picture books to keep children entertained during long car trips."

[0914] As described above, it is possible to realize an in-car entertainment system that can quickly respond to a variety of user requests.

[0915] The flow of the identification process in the first embodiment will be described with reference to FIG.

[0916] Step 1: Receiving and Recognizing Voice Commands

[0917] Input: The user issues a voice command.

[0918] Specific operation: When the user issues a voice command such as "sing a song," the device's built-in microphone captures the audio.

[0919] Data processing: The device's voice recognition module converts the voice into text data using the Google Cloud Speech-to-Text API.

[0920] Output: The audio is output as text data saying "Sing a song."

[0921] Step 2: Parse the text data and send a request to the server

[0922] Input: The text data "Sing a song" generated in step 1.

[0923] Specific operation: The text analysis module of the terminal receives the text data and analyzes the content of the command.

[0924] Data processing: Through analysis, the user's intended command (in this case, "play music") is understood.

[0925] Output: A request specifying the "song ID" is generated and sent to the server.

[0926] Step 3: Retrieving content from the database

[0927] Input: The request sent from the device to the server (the specified "song ID").

[0928] What happens: The server receives the request and searches the database for the specified content.

[0929] Data processing: The server retrieves music data related to the corresponding "song ID" from a database (e.g., cloud storage).

[0930] Output: The retrieved music data is prepared by the server.

[0931] Step 4: Sending content from the server to the device

[0932] Input: Music data obtained in step 3.

[0933] Specific operation: The server sends music data to the terminal.

[0934] Data processing: Data is transferred securely using the HTTPS protocol.

[0935] Output: Music data is sent to the device.

[0936] Step 5: Playing content

[0937] Input: Music data sent to the device.

[0938] Specific operation: The music player module of the terminal plays the received music data.

[0939] Data processing: Decodes music data and converts it into an audio signal.

[0940] Output: The user can listen to the music.

[0941] Step 6: Logging user activity

[0942] Input: User commands and information about the content being played.

[0943] Specific operation: The server collects information such as the user's command, activity time, and song ID.

[0944] Data processing: The server compiles this information as log data and stores it in storage.

[0945] Output: Log data recorded as system usage history.

[0946] Through the above processing steps, appropriate content is provided in real time based on the user's commands, realizing an entertainment environment in the car.

[0947] (Application example 1)

[0948] Next, a description will be given of Application Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the headset type terminal 314 will be referred to as a "terminal."

[0949] One problem with food delivery services is that children can get bored while waiting or eating. This requires parents and guardians to put in a lot of effort to keep their children from getting bored, which can make using delivery services stressful. Furthermore, boredom can affect children's behavior while eating.

[0950] The specific processing by the specific processing unit 290 of the data processing device 12 in the application example 1 is realized by the following means.

[0951] In this invention, the server includes: a means for a user to send commands by voice or text; a means for the server to retrieve specified content (songs, picture books, conversation data, children's entertainment, dining place information, activity information, etc.) from a database; a means for the terminal to play or display the retrieved content; a means for the server to log the user's activities; and a means for providing children's entertainment content while ordering a meal or while waiting. This allows children to enjoy their waiting time or while eating without getting bored, significantly reducing the burden on parents and guardians.

[0952] "User" means a person who utilizes the system to send commands by voice or text.

[0953] "Means for sending voice or text commands" means a method by which a user can send specific instructions to the system using voice or text input.

[0954] A "server" is a computer system that retrieves specified content from a database based on a user's command and transmits it to a terminal.

[0955] "Content" refers to items that the server retrieves from the database, such as songs, picture books, conversation data, children's entertainment, dining information, and activity information.

[0956] "Database" means a system that manages and stores content and provides data upon request.

[0957] A "terminal" is a device that allows a user to send commands by voice or text input and plays or displays content retrieved from a server.

[0958] "Means for playing or displaying" refers to the function of the terminal to play acquired content as audio or display it on the screen.

[0959] "Means for recording in a log" refers to a function that allows the server to save the details of user activities as recorded data.

[0960] "Means of providing entertainment content for children while ordering or waiting for a meal" refers to a method of providing content that children using a food delivery service can enjoy while ordering or waiting for their food to arrive.

[0961] "Entertainment content" refers to various entertainment elements that children can enjoy, such as songs, picture books, videos, and games.

[0962] The present invention aims to realize a system for providing entertainment for children in a food delivery service. A specific embodiment of this system will be described below.

[0963] System configuration

[0964] The system uses the following hardware and software:

[0965] 1. Hardware: Smartphone or tablet (iOS or Android)

[0966] 2. Software: Server (e.g., AWS, Google Cloud), speech recognition library (e.g., Google Cloud Speech-to-Text API), database (e.g., MySQL, MongoDB)

[0967] Program generation and processing flow

[0968] User command transmission and voice recognition

[0969] The user sends commands to the device by voice or text, such as "sing a song" or "read a picture book." This command is converted into text data using a speech recognition library.

[0970] Data retrieval by the server

[0971] The recognized text data is sent from the device to the server, which then analyzes the user's commands and retrieves the corresponding content (e.g., music data for a song or text and audio data for a picture book) from a database.

[0972] Playing and displaying content

[0973] The acquired content is sent from the server to the device, where it is played or displayed. For example, a song is played on a music player, and a picture book is displayed with text on the screen and audio played.

[0974] Activity logging

[0975] The server records user activity (e.g., time of command transmission, type of content played, playback time, etc.) in a log, allowing the system usage history to be checked later.

[0976] Providing entertainment for children

[0977] While ordering or waiting for a food delivery service, the user can issue a command to "provide entertainment content for children," and the device will play entertainment content such as cartoons and games, allowing children to have fun while waiting without getting bored.

[0978] Specific examples

[0979] For example, if a user orders food delivery and their child starts to get bored while they are waiting, the user can command the device to "sing a song to my child," and the system will start playing the specified song. Similarly, if the user commands the device to "tell me about zoo activities," the server will retrieve zoo-related activity information from the database and display it on the device.

[0980] Prompt Sentence Examples

[0981] "Please explain in detail how it works if you sing a song and send it as a voice command to the program."

[0982] "Please explain how requests for content retrieval are sent to the server."

[0983] "Please explain in detail how you would use voice recognition technology to ask questions and provide responses."

[0984] As described above, the system according to the present invention increases the convenience of food delivery services and provides an environment in which children can enjoy the waiting time.

[0985] The flow of the specific processing in the application example 1 will be described with reference to FIG.

[0986] Step 1:

[0987] The user sends commands to the terminal by voice or text. The input is voice or text data, and the output is the transmission of voice or text commands. Specifically, the user voice-inputs "sing a song."

[0988] Step 2:

[0989] The device uses voice recognition technology to convert voice commands into text data. The input is voice data and the output is text data. Specifically, the Google Cloud Speech-to-Text API is used to convert the voice data "Sing me a song" into the text data "Sing me a song."

[0990] Step 3:

[0991] The terminal sends the converted text data to the server. The input is text data, and the output is a request sent to the server. Specifically, the text data "Sing a song" is sent to the server.

[0992] Step 4:

[0993] The server analyzes the received text data and retrieves the corresponding content from the database. The input is text data, and the output is the retrieved content data. Specifically, the server analyzes the request "Sing a song" and retrieves the music data of the specified song from the database.

[0994] Step 5:

[0995] The server transmits the acquired content data to the terminal. The input is the content data, and the output is data transmission to the terminal. Specifically, the music data of the song is transmitted to the terminal.

[0996] Step 6:

[0997] The terminal receives the content data sent from the server and plays or displays it. The input is the content data, and the output is the playback or display of the content. Specifically, the terminal plays the music data of the song received on a music player.

[0998] Step 7:

[0999] The server records user activity in a log. The input is the user's command and content playback information, and the output is log data. Specifically, the log records the time the command was sent, the type of song played, and the playback time.

[1000] Step 8:

[1001] If the user sends a new command while ordering or waiting for food, the same process is repeated. The input is a new voice or text command, and the output is the provision of new content. Specifically, if the user commands, "Tell me about zoo activities," the server retrieves zoo activity information from the database and displays it on the device.

[1002] Furthermore, an emotion engine that estimates the user's emotion may be further combined. That is, the identification processing unit 290 may estimate the user's emotion using the emotion identification model 59, and perform identification processing using the user's emotion.

[1003] The present invention is a system installed in a child car seat that allows the user to operate it using voice or text, recognizes the user's emotions, and provides appropriate content, allowing the user to have a comfortable and enjoyable time even during long car trips. Specific embodiments of this system are described below.

[1004] First, consider a scenario where a user sends a command to a car seat by voice or text. For example, the user commands, "Sing me a song." This command is recognized by a terminal built into the car seat. The terminal analyzes the command and requests the necessary data from a server.

[1005] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[1006] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[1007] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[1008] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[1009] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[1010] The present invention also incorporates an emotion engine. The emotion engine analyzes the user's voice data and facial expression data to recognize the user's emotional state. For example, if a child is in a bad mood, the emotion engine recognizes that emotion and is configured to provide more enjoyable content preferentially. Therefore, even if the user commands "sing a song," the server selects a song of an appropriate genre based on the emotional state recognized by the emotion engine. In this way, the user's emotional state can be monitored in real time and recorded in a log.

[1011] Consider the following scenario as a concrete example: A family is traveling in a car and their child starts to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo so that the child can look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine will recognize this state and prioritize providing comforting stories and music.

[1012] In this way, the system of the present invention adapts to the user's emotional state to provide an environment that keeps children interested even during long car trips and allows parents to concentrate on driving safely.

[1013] The processing flow will be explained below.

[1083] In this way, the system is designed to provide appropriate content based on the user's emotional state, allowing them to spend a comfortable and enjoyable time.

[1084] Example 2

[1085] Next, a description will be given of Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the headset type terminal 314 will be referred to as a "terminal."

[1086] The challenge is to reduce boredom and discomfort for children during long car trips and provide an environment where parents can concentrate on driving safely.It is also necessary to provide content that suits the user's emotional state and maintain the child's interest.

[1087] The specific processing by the specific processing unit 290 of the data processing device 12 in the second embodiment is realized by the following means. In this invention, the server includes means for transmitting commands by the user's voice or text, means for the terminal to analyze the user's command using voice recognition technology and transmit the analysis result to the server, means for the server to acquire specified content (such as a song, a picture book, or conversation data) from a database, means for the server to transmit the acquired content to the terminal, means for the terminal to play or display the acquired content, and means for the server to record information such as the command reception time, song ID, and playback time in a log. This makes it possible to provide content that suits the user's emotional state, keep children interested even during long car trips, and provide an environment where parents can concentrate on driving safely.

[1088] "User" refers to a person who uses the system to send commands by voice or text.

[1089] "Terminal" refers to a device built into a child car seat that recognizes and analyzes user commands and plays or displays data.

[1090] "Speech recognition technology" refers to technology that converts the voice spoken by a user into text data.

[1091] A "server" refers to a computer system that retrieves content from a database based on instructions sent from a terminal and sends it to the terminal.

[1092] "Database" refers to a storage system in which content (songs, picture books, conversation data, etc.) is stored.

[1093] "Content" refers to information such as songs, picture books, conversation data, etc. provided to users.

[1094] "Log" refers to a file or data structure that records system usage (time of command reception, song ID, playback time, etc.).

[1095] "Emotional state" refers to the user's mood and emotions at that time, as analyzed from their voice and facial expressions.

[1096] An "emotion engine" refers to an algorithm that analyzes a user's voice and facial expression data to recognize their emotional state.

[1097] "Activities" refers to events and information related to a specified destination.

[1098] The present invention is a system installed in a child car seat that can be operated by the user using voice or text, recognizes the user's emotions, and provides appropriate content, allowing children to have a comfortable and enjoyable time even during long car trips.

[1099] First, the user sends a command to the car seat by voice or text. For example, "Sing a song." This command is recognized by a device built into the car seat. The hardware uses a voice recognition microphone, and the software uses the Google voice recognition API. The device converts the voice into text data, analyzes the command, and extracts the specific request.

[1100] Next, the device sends the parsed command to the server using an HTTP request. The server analyzes the received command and retrieves the content corresponding to the command from a database (e.g., MySQL). The retrieved content (e.g., music data) is then sent from the server to the device.

[1101] The device plays or displays the received content. Specifically, if it is music data, it will be played on the built-in music player, and if it is a picture book, it will display the text on the screen and play the audio data. This allows the user to enjoy the music or picture book.

[1102] The server also records information such as the time the request was received, the song ID, and the playback time as a log. For this purpose, Elasticsearch is used, making it possible to check the system usage history later.

[1103] Furthermore, the system is equipped with an emotion engine. The emotion engine acquires the user's voice and facial expression data through the device and sends it to the server. The server then uses the emotion engine (for example, Microsoft Azure Face API) to analyze the user's emotional state. Based on the analysis results, the server selects content appropriate to the user's emotional state and sends it to the device. For example, if the user commands "sing a song," the emotion engine will select a song from an appropriate genre based on the emotional state it recognizes.

[1104] Consider the following scenario as a concrete example: A family is traveling in a car and a child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands "Let's go to the zoo" just before arriving at their destination, the server retrieves information and activities related to the zoo from a database and displays that information on the device, allowing the child to look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine recognizes this state and prioritizes providing comforting stories and music.

[1105] An example of a prompt is as follows:

[1106] "Play this children's song"

[1107] "Read the picture book 'Little Red Riding Hood' aloud."

[1108] "Make plans to go to the zoo."

[1109] In this way, the system of the present invention adapts to the user's emotional state and provides appropriate content, thereby keeping children interested even during long car trips and providing an environment where parents can concentrate on driving safely.

[1110] The flow of the identification process in the second embodiment will be described with reference to FIG.

[1134] Input: Content data received from the server (e.g. music data).

[1135] Output: The music that is played or the text and images that are displayed.

[1136] What it does: The device's built-in music player plays music, which the child listens to.

[1137] Step 6:

[1138] The server logs information such as the time the command was received, the content ID, and the playback time.

[1139] Input: Received command data, content ID, playback time.

[1140] Output: Log data.

[1141] Specific operation: The server uses Elasticsearch to save the information "Song ID 123 started playing at 15:30:00 on 2023-10-12 and finished at 15:35:00" in the log.

[1142] Step 7:

[1143] The device captures the user's voice and facial expression data and sends it to the server, where it is analyzed using an emotion engine.

[1144] Input: User's voice and facial expression data.

[1145] Output: Emotion analysis results.

[1146] How it works: The device's camera and microphone capture the user's facial expressions and voice, and then send the data to the server, where it is analyzed using the emotion engine (Microsoft Azure Face API).

[1147] Step 8:

[1148] The server selects appropriate content based on the emotional state and sends it to the terminal.

[1149] Input: Sentiment analysis results.

[1150] Output: Content data appropriate to the user's emotional state.

[1151] Specific operation: Based on the results of the emotion analysis, the server retrieves uplifting songs and comforting stories from the database again and sends them to the device.

[1152] Through the above processing steps, the user can enjoy appropriate content through the child car seat and be provided with a comfortable experience optimized for their emotional state.

[1153] (Application example 2)

[1154] Next, a description will be given of Application Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the headset type terminal 314 will be referred to as a "terminal."

[1155] Conventional child seat systems often fail to provide comfort or enjoyment for children during long car trips. In particular, they often fail to provide content tailored to a child's emotional state, leading to boredom or irritability. Furthermore, they offer limited information about destinations and activities, making it difficult for children to stay interested during the trip.

[1156] The specific processing by the specific processing unit 290 of the data processing device 12 in Application Example 2 is realized by the following means. In this invention, the server includes: means for the user to send commands by voice or text; means for the server to acquire specified content (music, story, dialogue data, etc.) from a database; means for the terminal to play or display the acquired content; means for the server to record the user's activities in a log; and means for analyzing the user's emotional state using emotion recognition technology and providing content accordingly. This makes it possible to provide appropriate content according to the user's emotional state, allowing children to spend a comfortable and enjoyable time even during long car trips.

[1157] A "means for users to send commands by voice or text" is a device or function that allows a user to send commands or requests to a system using voice or text input.

[1158] "Means for the server to retrieve specified content (music, story, dialogue data, etc.) from a database" refers to a method or device that allows the server to search for and retrieve specific content stored in a database.

[1159] The "means for the terminal to play or display the acquired content" refers to a device or function for the terminal to play or visually present the content received from the server.

[1160] "Means for the server to log user activity" refers to a mechanism that allows the server to record user operations and system operation status so that they can be checked later.

[1161] "Means for analyzing a user's emotional state using emotion recognition technology and providing content in accordance with that state" refers to technology or devices that grasp a user's emotional state by analyzing voice data and facial expression data, and select and provide content appropriate to that state.

[1162] This invention relates to a child car seat system for use in autonomous vehicles. In this system, a user sends commands using voice or text, a server retrieves specified content from a database, and a terminal plays or displays the retrieved content. Furthermore, emotion recognition technology is used to analyze the user's emotional state and provide content appropriate to the user's emotional state.

[1163] The system hardware configuration uses a smartphone or a head-mounted display. These devices include a microphone and speaker for audio input and output, and a display for video display. These devices communicate with a cloud server via the Internet.

[1164] The cloud server utilizes the following software and platforms:

[1165] Speech recognition technology: Google Cloud Speech-to-Text API

[1166] Emotion recognition technology: Microsoft Azure Emotion API

[1167] Content management and delivery: AWS Lambda, AWS RDS, and DynamoDB

[1168] Response generation: OpenAI's GPT-4

[1169] From the perspective of generating the system's programs, when a user sends a command via voice or text, the command is first analyzed locally via a smartphone or head-mounted display. The command is then sent to a cloud server, which retrieves appropriate content from a database based on the command. For example, if a user commands "sing a song," the server selects uplifting music content and sends it to the device, which then plays the music.

[1170] The process of analyzing the user's emotional state using emotion recognition technology also takes place on a cloud server. The user's voice and facial expression data are analyzed using Microsoft Azure's Emotion API, and the most appropriate content is selected based on that emotional state. For example, if a child is anxious, a reassuring story can be provided. For this reason, the emotion recognition engine can also monitor the user's emotional state in real time and record it in a log.

[1171] For example, if a child says, "Tell me about the zoo" while traveling in a family car, the cloud server retrieves information about the zoo from the database and sends it to the device. The device then uses a display device to present a map of the zoo and an animal quiz to the user.

[1172] Examples of prompts include:

[1173] Music Play Prompt: "Please play a happy song for the child who is feeling a bit down."

[1174] Picture Book Reading Prompt: "Read an engaging storybook to the child to keep their attention during the trip."

[1175] Informational prompt: "Provide interesting facts about the zoo and animals for the child's query about the zoo."

[1176] This allows children to have a comfortable and enjoyable time even during long car trips, while providing an environment where parents can concentrate on driving safely.

[1177] The flow of the specific processing in the application example 2 will be described with reference to FIG.

[1178] Step 1:

[1179] The user sends commands to the device by voice or text. The user's voice data or text data is collected by a smartphone or head-mounted display. The input is the user's voice command or text command, and the output is the voice data or text data.

[1180] Step 2:

[1181] The device converts voice data into text using voice recognition technology (Google Cloud Speech-to-Text API). The input is voice data and the output is text data. At this time, the device analyzes the voice command and sends it as text to the cloud server.

[1182] Step 3:

[1183] The server analyzes the received command text and retrieves the corresponding content (music, story, dialogue data, etc.) from the database. The input is the command text, and the output is the content data (music file, text file, audio file, etc.). The server searches the database for data based on the content ID corresponding to the command.

[1184] Step 4:

[1185] The server uses emotion recognition technology (Microsoft Azure's Emotion API) to analyze the user's voice data and facial expression data and evaluate the user's emotional state. The input is voice data and facial expression data, and the output is the user's emotional state (e.g., joy, sadness, excitement, etc.). Based on the results of this analysis, the server selects appropriate content.

[1186] Step 5:

[1187] The server selects appropriate content and sends it to the terminal. The input is the selected content data, and the output is the content data to be sent to the terminal. The server sends the data to the terminal through the network.

[1188] Step 6:

[1189] The device plays or displays the received content in an appropriate format. The input is the content data, and the output is a format that the user can view (e.g., playing music, displaying a story, etc.). The device provides the acquired content to the user.

[1190] Step 7:

[1191] The server logs all commands, responses, and emotional states. The input is data such as command text, content ID, and emotional state, and the output is records in a log file or database. The server stores this information for later review.

[1192] Step 8:

[1193] If the user issues an additional command, the process repeats, returning to step 1. The input is again the user's voice or text command, and the output is the provision of new content.

[1194] As a result, a system is realized that allows users to enjoy content comfortably and enjoyably even during long car trips.

[1195] The specific processing unit 290 transmits the result of the specific processing to the headset type terminal 314. In the headset type terminal 314, the control unit 46A causes the speaker 240 and the display 343 to output the result of the specific processing. The microphone 238 acquires audio indicating a user input regarding the result of the specific processing. The control unit 46A transmits audio data indicating the user input acquired by the microphone 238 to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the audio data.

[1196] The data generation model 58 is a so-called generative AI (Artificial Intelligence). An example of the data generation model 58 is ChatGPT (Internet Search<URL: https: / / openai.com / blog / chatgpt> ), Gemini (Internet search <url: https: gemini.google.com ?hl="ja">) and other generation AIs. The data generation model 58 is obtained by performing deep learning on a neural network. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating voice, text data indicating text, and image data indicating an image is also input. The data generation model 58 performs inference on the input inference data in accordance with the instruction indicated by the prompt, and outputs the inference result in a data format such as voice data and text data. Here, inference refers to, for example, analysis, classification, prediction, and / or summarization.

[1197] In the above embodiment, an example was given in which the specific processing is performed by the data processing device 12, but the technology of the present disclosure is not limited to this, and the specific processing may be performed by the headset type terminal 314.

[1198] [Fourth embodiment]

[1199] FIG. 7 shows an example of the configuration of a data processing system 410 according to the fourth embodiment.

[1200] 7, a data processing system 410 includes a data processing device 12 and a robot 414. An example of the data processing device 12 is a server.

[1201] The data processing device 12 includes a computer 22, a database 24, and a communication I / F 26. The computer 22 is an example of a "computer" according to the technology of the present disclosure. The computer 22 includes a processor 28, a RAM 30, and a storage 32. The processor 28, the RAM 30, and the storage 32 are connected to a bus 34. The database 24 and the communication I / F 26 are also connected to the bus 34. The communication I / F 26 is connected to a network 54. Examples of the network 54 include a WAN (Wide Area Network) and / or a LAN (Local Area Network).

[1202] The robot 414 includes a computer 36, a microphone 238, a speaker 240, a camera 42, a communication I / F 44, and a control target 443. The computer 36 includes a processor 46, a RAM 48, and a storage 50. The processor 46, the RAM 48, and the storage 50 are connected to a bus 52. The microphone 238, the speaker 240, the camera 42, and the control target 443 are also connected to the bus 52.

[1203] The microphone 238 receives instructions and the like from the user 20 by receiving voice uttered by the user 20. The microphone 238 captures the voice uttered by the user 20, converts the captured voice into audio data, and outputs it to the processor 46. The speaker 240 outputs audio in accordance with instructions from the processor 46.

[1204] Camera 42 is a small digital camera equipped with an optical system including a lens, aperture, and shutter, and an imaging element such as a CMOS (Complementary Metal-Oxide-Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor, and captures images of the surroundings of user 20 (for example, an imaging range defined by an angle of view equivalent to the field of vision of a typical healthy person).

[1205] The communication I / F 44 is connected to a network 54. The communication I / Fs 44 and 26 control the exchange of various information between the processor 46 and the processor 28 via the network 54. The exchange of various information between the processor 46 and the processor 28 using the communication I / Fs 44 and 26 is carried out in a secure state.

[1206] The control object 443 includes a display device, LEDs in the eyes, and motors for driving the arms, hands, and feet. The posture and gestures of the robot 414 are controlled by controlling the motors of the arms, hands, and feet. Some of the emotions of the robot 414 can be expressed by controlling these motors. In addition, the facial expressions of the robot 414 can also be expressed by controlling the light emission state of the LEDs in the eyes of the robot 414.

[1207] Fig. 8 shows an example of the main functions of the data processing device 12 and the robot 414. As shown in Fig. 8, in the data processing device 12, a specific process is performed by the processor 28. A specific process program 56 is stored in the storage 32.

[1208] The specific processing program 56 is an example of a "program" according to the technology of the present disclosure. The processor 28 reads the specific processing program 56 from the storage 32 and executes the read specific processing program 56 on the RAM 30. The specific processing is realized by the processor 28 operating as a specific processing unit 290 in accordance with the specific processing program 56 executed on the RAM 30.

[1209] The storage 32 stores a data generation model 58 and an emotion identification model 59. The data generation model 58 and the emotion identification model 59 are used by the identification processing unit 290.

[1210] In the robot 414, the processor 46 performs the reception output process. A reception output program 60 is stored in the storage 50. The processor 46 reads the reception output program 60 from the storage 50 and executes the read reception output program 60 on the RAM 48. The reception output process is realized by the processor 46 operating as the control unit 46A in accordance with the reception output program 60 executed on the RAM 48.

[1211] Next, a description will be given of the specific processing performed by the specific processing unit 290 of the data processing device 12. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."

[1212] The present invention is a system mounted on a child car seat that can be operated by a user using voice or text. Specific embodiments of this system will be described below.

[1213] First, the user sends a command to the car seat by voice or text. For example, the user commands "sing a song." This command is recognized by the terminal built into the car seat. The terminal analyzes the command and requests the necessary data from the server.

[1214] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[1215] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[1216] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[1217] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[1218] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[1219] Consider the following scenario as a concrete example: A family is traveling in a car and their child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system starts playing the song, allowing the child to enjoy the music. Next, if the child says, "I want you to read me a picture book," the system will display the specified picture book and read it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo, helping the child look forward to having fun at the zoo.

[1220] In this way, the system according to the present invention provides an environment in which children can remain interested even during long car journeys and parents can concentrate on driving safely.

[1282] In this way, each process proceeds and the function requested by the user is realized.

[1283] Example 1

[1284] Next, a description will be given of Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."

[1285] Previous in-car entertainment systems were limited in the types of content and operation methods, making it difficult to keep children interested, especially during long car trips. There was also a need for an effective system that could quickly respond to user commands and provide a variety of content. Furthermore, there was a lack of a mechanism for recording user command history and system usage and using that information to improve services.

[1286] The specific processing by the specific processing unit 290 of the data processing device 12 in the first embodiment is realized by the following means.

[1287] In this invention, the server includes a means for a user to send commands by voice or text, a means for converting the voice into text using a voice recognition module, and a means for analyzing the commands using a text analysis module and sending a request to the server, thereby enabling rapid response to various user requests and providing a comfortable entertainment environment in the car.

[1288] "User" refers to the person who operates the system and sends commands using voice or text.

[1289] A "voice recognition module" refers to hardware or software that has the function of converting voice into text data.

[1290] "Text analysis module" refers to hardware or software that has the function of analyzing text data generated by the voice recognition module and generating instructions according to the content of the data.

[1291] A "server" refers to a computer system that communicates with a terminal via a network, retrieves specified content from a database, and transmits it to the terminal.

[1292] "Database" refers to a storage device in which the server stores content (music data, text data, voice data, etc.).

[1293] "Terminal" refers to a device through which a user sends instructions and plays or displays content received from a server.

[1294] "Log" refers to data that a server records, such as user activity and system usage.

[1295] "Content" refers to information and services (e.g., music data, picture book data, conversation data, etc.) provided by a server in response to a user's commands.

[1296] The "HTTPS protocol" refers to a communication protocol for securely transmitting data over the Internet.

[1297] The present invention is a system for providing entertainment for children in a car. A user can send commands to a terminal using voice or text, and the system responds by providing appropriate content.

[1298] First, when a user issues a voice command, such as "sing a song," the device's built-in microphone captures the voice. Next, the voice recognition module converts the voice into text using the Google Cloud Speech-to-Text API. The converted text is then analyzed by the text analysis module to understand the command.

[1299] The parsed command is sent as a request to the server, which retrieves the content corresponding to that command from its database. For example, if a song command is issued, the server searches for the corresponding music data in the database and sends it to the device. In this case, data is transferred securely using HTTPS as the communication protocol.

[1300] The terminal plays the received music data on the music player module, allowing the user to enjoy the music. Similarly, when a user issues a command to "read a picture book," the server retrieves the corresponding text data and audio data and displays and plays them on the terminal.

[1301] The server also logs user activity and system usage, allowing us to review system usage history and improve our services.

[1302] Consider the following scenarios as specific examples: If a child gets bored while traveling by car with a family, the parent can command "Sing a song" and the system will play the corresponding song, allowing the child to enjoy the music. Also, if the parent commands "Let's go to the zoo" before arriving, the server will retrieve activity information about the zoo and the device will display that information, allowing the child to enjoy knowing what to expect before arriving.

[1303] An example of a prompt sentence might be:

[1304] "Tell me more about your in-car entertainment system. The system recognizes voice commands, retrieves data from a server, and plays it."

[1305] "Describe a system that uses voice recognition to play songs and picture books to keep children entertained during long car trips."

[1306] As described above, it is possible to realize an in-car entertainment system that can quickly respond to a variety of user requests.

[1307] The flow of the identification process in the first embodiment will be described with reference to FIG.

[1308] Step 1: Receiving and Recognizing Voice Commands

[1309] Input: The user issues a voice command.

[1310] Specific operation: When the user issues a voice command such as "sing a song," the device's built-in microphone captures the audio.

[1311] Data processing: The device's voice recognition module converts the voice into text data using the Google Cloud Speech-to-Text API.

[1312] Output: The audio is output as text data saying "Sing a song."

[1313] Step 2: Parse the text data and send a request to the server

[1314] Input: The text data "Sing a song" generated in step 1.

[1315] Specific operation: The text analysis module of the terminal receives the text data and analyzes the content of the command.

[1316] Data processing: Through analysis, the user's intended command (in this case, "play music") is understood.

[1317] Output: A request specifying the "song ID" is generated and sent to the server.

[1318] Step 3: Retrieving content from the database

[1319] Input: The request sent from the device to the server (the specified "song ID").

[1320] What happens: The server receives the request and searches the database for the specified content.

[1321] Data processing: The server retrieves music data related to the corresponding "song ID" from a database (e.g., cloud storage).

[1322] Output: The retrieved music data is prepared by the server.

[1323] Step 4: Sending content from the server to the device

[1324] Input: Music data obtained in step 3.

[1325] Specific operation: The server sends music data to the terminal.

[1326] Data processing: Data is transferred securely using the HTTPS protocol.

[1327] Output: Music data is sent to the device.

[1328] Step 5: Playing content

[1329] Input: Music data sent to the device.

[1330] Specific operation: The music player module of the terminal plays the received music data.

[1331] Data processing: Decodes music data and converts it into an audio signal.

[1332] Output: The user can listen to the music.

[1333] Step 6: Logging user activity

[1334] Input: User commands and information about the content being played.

[1335] Specific operation: The server collects information such as the user's command, activity time, and song ID.

[1336] Data processing: The server compiles this information as log data and stores it in storage.

[1337] Output: Log data recorded as system usage history.

[1338] Through the above processing steps, appropriate content is provided in real time based on the user's commands, realizing an entertainment environment in the car.

[1339] (Application example 1)

[1340] Next, a description will be given of Application Example 1. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."

[1341] One problem with food delivery services is that children can get bored while waiting or eating. This requires parents and guardians to put in a lot of effort to keep their children from getting bored, which can make using delivery services stressful. Furthermore, boredom can affect children's behavior while eating.

[1342] The specific processing by the specific processing unit 290 of the data processing device 12 in the application example 1 is realized by the following means.

[1343] In this invention, the server includes: a means for a user to send commands by voice or text; a means for the server to retrieve specified content (songs, picture books, conversation data, children's entertainment, dining place information, activity information, etc.) from a database; a means for the terminal to play or display the retrieved content; a means for the server to log the user's activities; and a means for providing children's entertainment content while ordering a meal or while waiting. This allows children to enjoy their waiting time or while eating without getting bored, significantly reducing the burden on parents and guardians.

[1344] "User" means a person who utilizes the system to send commands by voice or text.

[1345] "Means for sending voice or text commands" means a method by which a user can send specific instructions to the system using voice or text input.

[1346] A "server" is a computer system that retrieves specified content from a database based on a user's command and transmits it to a terminal.

[1348] "Database" means a system that manages and stores content and provides data upon request.

[1349] A "terminal" is a device that allows a user to send commands by voice or text input and plays or displays content retrieved from a server.

[1350] "Means for playing or displaying" refers to the function of the terminal to play acquired content as audio or display it on the screen.

[1351] "Means for recording in a log" refers to a function that allows the server to save the details of user activities as recorded data.

[1352] "Means of providing entertainment content for children while ordering or waiting for a meal" refers to a method of providing content that children using a food delivery service can enjoy while ordering or waiting for their food to arrive.

[1353] "Entertainment content" refers to various entertainment elements that children can enjoy, such as songs, picture books, videos, and games.

[1354] The present invention aims to realize a system for providing entertainment for children in a food delivery service. A specific embodiment of this system will be described below.

[1355] System configuration

[1356] The system uses the following hardware and software:

[1357] 1. Hardware: Smartphone or tablet (iOS or Android)

[1358] 2. Software: Server (e.g., AWS, Google Cloud), speech recognition library (e.g., Google Cloud Speech-to-Text API), database (e.g., MySQL, MongoDB)

[1359] Program generation and processing flow

[1360] User command transmission and voice recognition

[1361] The user sends commands to the device by voice or text, such as "sing a song" or "read a picture book." This command is converted into text data using a speech recognition library.

[1362] Data retrieval by the server

[1363] The recognized text data is sent from the device to the server, which then analyzes the user's commands and retrieves the corresponding content (e.g., music data for a song or text and audio data for a picture book) from a database.

[1364] Playing and displaying content

[1365] The acquired content is sent from the server to the device, where it is played or displayed. For example, a song is played on a music player, and a picture book is displayed with text on the screen and audio played.

[1366] Activity logging

[1367] The server records user activity (e.g., time of command transmission, type of content played, playback time, etc.) in a log, allowing the system usage history to be checked later.

[1368] Providing entertainment for children

[1369] While ordering or waiting for a food delivery service, the user can issue a command to "provide entertainment content for children," and the device will play entertainment content such as cartoons and games, allowing children to have fun while waiting without getting bored.

[1370] Specific examples

[1371] For example, if a user orders food delivery and their child starts to get bored while they are waiting, the user can command the device to "sing a song to my child," and the system will start playing the specified song. Similarly, if the user commands the device to "tell me about zoo activities," the server will retrieve zoo-related activity information from the database and display it on the device.

[1372] Prompt Sentence Examples

[1373] "Please explain in detail how it works if you sing a song and send it as a voice command to the program."

[1374] "Please explain how requests for content retrieval are sent to the server."

[1375] "Please explain in detail how you would use voice recognition technology to ask questions and provide responses."

[1376] As described above, the system according to the present invention increases the convenience of food delivery services and provides an environment in which children can enjoy the waiting time.

[1377] The flow of the specific processing in the application example 1 will be described with reference to FIG.

[1378] Step 1:

[1379] The user sends commands to the terminal by voice or text. The input is voice or text data, and the output is the transmission of voice or text commands. Specifically, the user voice-inputs "sing a song."

[1380] Step 2:

[1381] The device uses voice recognition technology to convert voice commands into text data. The input is voice data and the output is text data. Specifically, the Google Cloud Speech-to-Text API is used to convert the voice data "Sing me a song" into the text data "Sing me a song."

[1382] Step 3:

[1383] The terminal sends the converted text data to the server. The input is text data, and the output is a request sent to the server. Specifically, the text data "Sing a song" is sent to the server.

[1384] Step 4:

[1385] The server analyzes the received text data and retrieves the corresponding content from the database. The input is text data, and the output is the retrieved content data. Specifically, the server analyzes the request "Sing a song" and retrieves the music data of the specified song from the database.

[1386] Step 5:

[1387] The server transmits the acquired content data to the terminal. The input is the content data, and the output is data transmission to the terminal. Specifically, the music data of the song is transmitted to the terminal.

[1388] Step 6:

[1389] The terminal receives the content data sent from the server and plays or displays it. The input is the content data, and the output is the playback or display of the content. Specifically, the terminal plays the music data of the song received on a music player.

[1390] Step 7:

[1391] The server records user activity in a log. The input is the user's command and content playback information, and the output is log data. Specifically, the log records the time the command was sent, the type of song played, and the playback time.

[1392] Step 8:

[1393] If the user sends a new command while ordering or waiting for food, the same process is repeated. The input is a new voice or text command, and the output is the provision of new content. Specifically, if the user commands, "Tell me about zoo activities," the server retrieves zoo activity information from the database and displays it on the device.

[1394] Furthermore, an emotion engine that estimates the user's emotion may be further combined. That is, the identification processing unit 290 may estimate the user's emotion using the emotion identification model 59, and perform identification processing using the user's emotion.

[1395] The present invention is a system installed in a child car seat that allows the user to operate it using voice or text, recognizes the user's emotions, and provides appropriate content, allowing the user to have a comfortable and enjoyable time even during long car trips. Specific embodiments of this system are described below.

[1396] First, consider a scenario where a user sends a command to a car seat by voice or text. For example, the user commands, "Sing me a song." This command is recognized by a terminal built into the car seat. The terminal analyzes the command and requests the necessary data from a server.

[1397] The server receives the request and retrieves the content corresponding to the command from the database. For example, if a song command is issued, the server searches the database for music data corresponding to the specified song ID. At this point, the server sends the retrieved song data to the terminal.

[1398] The device then plays the received song data on its music player, allowing users to enjoy music while using a child car seat. Furthermore, the server can record information such as the time the request was received, the song ID, and the playback time as a log. This allows the system usage history to be checked later.

[1399] Next, consider the case where the user commands "Read a picture book." The user's command is recognized by the device, and the analyzed results are sent to the server. The server retrieves the text data and audio data corresponding to the specified picture book ID from the database. This data is sent to the device, and the text of the picture book is displayed on the device and the audio data is played.

[1400] When a user asks the system a question such as "What's your favorite color?", the device uses voice recognition technology to convert the question into text data and send it to the server. The server analyzes the question and generates an appropriate response. This response data is sent to the device and displayed.

[1401] Furthermore, when a user requests "Let's go to the zoo" while out and about, the server retrieves information and activities related to the zoo from the database based on this request. The device displays this information and notifies the child of activities they can enjoy.

[1402] The present invention also incorporates an emotion engine. The emotion engine analyzes the user's voice data and facial expression data to recognize the user's emotional state. For example, if a child is in a bad mood, the emotion engine recognizes that emotion and is configured to provide more enjoyable content preferentially. Therefore, even if the user commands "sing a song," the server selects a song of an appropriate genre based on the emotional state recognized by the emotion engine. In this way, the user's emotional state can be monitored in real time and recorded in a log.

[1403] Consider the following scenario as a concrete example: A family is traveling in a car and their child starts to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands, "Let's go to the zoo" just before arriving at their destination, the system will suggest activity information related to the zoo so that the child can look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine will recognize this state and prioritize providing comforting stories and music.

[1404] In this way, the system of the present invention adapts to the user's emotional state to provide an environment that keeps children interested even during long car trips and allows parents to concentrate on driving safely.

[1405] The processing flow will be explained below.

[1476] Example 2

[1477] Next, a description will be given of Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."

[1478] The challenge is to reduce boredom and discomfort for children during long car trips and provide an environment where parents can concentrate on driving safely.It is also necessary to provide content that suits the user's emotional state and maintain the child's interest.

[1479] The specific processing by the specific processing unit 290 of the data processing device 12 in the second embodiment is realized by the following means. In this invention, the server includes means for transmitting commands by the user's voice or text, means for the terminal to analyze the user's command using voice recognition technology and transmit the analysis result to the server, means for the server to acquire specified content (such as a song, a picture book, or conversation data) from a database, means for the server to transmit the acquired content to the terminal, means for the terminal to play or display the acquired content, and means for the server to record information such as the command reception time, song ID, and playback time in a log. This makes it possible to provide content that suits the user's emotional state, keep children interested even during long car trips, and provide an environment where parents can concentrate on driving safely.

[1480] "User" refers to a person who uses the system to send commands by voice or text.

[1481] "Terminal" refers to a device built into a child car seat that recognizes and analyzes user commands and plays or displays data.

[1482] "Speech recognition technology" refers to technology that converts the voice spoken by a user into text data.

[1483] A "server" refers to a computer system that retrieves content from a database based on instructions sent from a terminal and sends it to the terminal.

[1484] "Database" refers to a storage system in which content (songs, picture books, conversation data, etc.) is stored.

[1485] "Content" refers to information such as songs, picture books, conversation data, etc. provided to users.

[1486] "Log" refers to a file or data structure that records system usage (time of command reception, song ID, playback time, etc.).

[1487] "Emotional state" refers to the user's mood and emotions at that time, as analyzed from their voice and facial expressions.

[1488] An "emotion engine" refers to an algorithm that analyzes a user's voice and facial expression data to recognize their emotional state.

[1489] "Activities" refers to events and information related to a specified destination.

[1490] The present invention is a system installed in a child car seat that can be operated by the user using voice or text, recognizes the user's emotions, and provides appropriate content, allowing children to have a comfortable and enjoyable time even during long car trips.

[1491] First, the user sends a command to the car seat by voice or text. For example, "Sing a song." This command is recognized by a device built into the car seat. The hardware uses a voice recognition microphone, and the software uses the Google voice recognition API. The device converts the voice into text data, analyzes the command, and extracts the specific request.

[1492] Next, the device sends the parsed command to the server using an HTTP request. The server analyzes the received command and retrieves the content corresponding to the command from a database (e.g., MySQL). The retrieved content (e.g., music data) is then sent from the server to the device.

[1493] The device plays or displays the received content. Specifically, if it is music data, it will be played on the built-in music player, and if it is a picture book, it will display the text on the screen and play the audio data. This allows the user to enjoy the music or picture book.

[1494] The server also records information such as the time the request was received, the song ID, and the playback time as a log. For this purpose, Elasticsearch is used, making it possible to check the system usage history later.

[1495] Furthermore, the system is equipped with an emotion engine. The emotion engine acquires the user's voice and facial expression data through the device and sends it to the server. The server then uses the emotion engine (for example, Microsoft Azure Face API) to analyze the user's emotional state. Based on the analysis results, the server selects content appropriate to the user's emotional state and sends it to the device. For example, if the user commands "sing a song," the emotion engine will select a song from an appropriate genre based on the emotional state it recognizes.

[1496] Consider the following scenario as a concrete example: A family is traveling in a car and a child begins to get bored. At that time, the parent commands the child seat to "sing a song." The system's emotion engine recognizes that the child is in a slightly bad mood and plays an uplifting song. Next, if the child says, "I want you to read me a picture book," the system uses the emotion engine to select a picture book that the child is interested in, and displays and reads it aloud. Furthermore, if the parent commands "Let's go to the zoo" just before arriving at their destination, the server retrieves information and activities related to the zoo from a database and displays that information on the device, allowing the child to look forward to having fun at the zoo. Furthermore, if the child becomes anxious during the trip, the emotion engine recognizes this state and prioritizes providing comforting stories and music.

[1497] An example of a prompt is as follows:

[1498] "Play this children's song"

[1499] "Read the picture book 'Little Red Riding Hood' aloud."

[1500] "Make plans to go to the zoo."

[1501] In this way, the system of the present invention adapts to the user's emotional state and provides appropriate content, thereby keeping children interested even during long car trips and providing an environment where parents can concentrate on driving safely.

[1502] The flow of the identification process in the second embodiment will be described with reference to FIG.

[1503] Processing Step Description

[1504] Step 1:

[1505] The user sends commands to the system by voice or text.

[1506] Input: User's voice or text command (e.g., "Sing me a song").

[1507] Output: Voice data captured by a voice recognition microphone or text data entered directly.

[1508] Specific action: The child says to the car seat, "Sing me a song."

[1509] Step 2:

[1510] The device uses voice recognition technology to analyze the user's commands, convert them into text, and send the results of the analysis to the server.

[1511] Input: Audio or text data.

[1512] Output: Text instruction data sent to the server (e.g. "Sing me a song").

[1513] Specific operation: The device uses the Google speech recognition API to convert the voice data into text data and sends the command "sing a song" to the server.

[1514] Step 3:

[1515] The server receives and parses the command and retrieves content from the database based on the command.

[1516] Input: Text instruction data received from the terminal (e.g., "Sing me a song").

[1517] Output: The specified content data (e.g. music data).

[1518] What happens: The server parses the command and retrieves the music data based on the corresponding song ID from the MySQL database.

[1519] Step 4:

[1520] The server transmits the acquired content data to the terminal.

[1521] Input: Content data retrieved from a database (e.g., music data).

[1522] Output: Content data sent to the device.

[1523] Specific operation: The server sends music data to the device using the HTTP protocol.

[1524] Step 5:

[1525] The device plays (or displays) the received content on a music player.

[1526] Input: Content data received from the server (e.g. music data).

[1527] Output: The music that is played or the text and images that are displayed.

[1528] What it does: The device's built-in music player plays music, which the child listens to.

[1529] Step 6:

[1530] The server logs information such as the time the command was received, the content ID, and the playback time.

[1531] Input: Received command data, content ID, playback time.

[1532] Output: Log data.

[1533] Specific operation: The server uses Elasticsearch to save the information "Song ID 123 started playing at 15:30:00 on 2023-10-12 and finished at 15:35:00" in the log.

[1534] Step 7:

[1535] The device captures the user's voice and facial expression data and sends it to the server, where it is analyzed using an emotion engine.

[1536] Input: User's voice and facial expression data.

[1537] Output: Emotion analysis results.

[1538] How it works: The device's camera and microphone capture the user's facial expressions and voice, and then send the data to the server, where it is analyzed using the emotion engine (Microsoft Azure Face API).

[1539] Step 8:

[1540] The server selects appropriate content based on the emotional state and sends it to the terminal.

[1541] Input: Sentiment analysis results.

[1542] Output: Content data appropriate to the user's emotional state.

[1543] Specific operation: Based on the results of the emotion analysis, the server retrieves uplifting songs and comforting stories from the database again and sends them to the device.

[1544] Through the above processing steps, the user can enjoy appropriate content through the child car seat and be provided with a comfortable experience optimized for their emotional state.

[1545] (Application example 2)

[1546] Next, a description will be given of Application Example 2. In the following description, the data processing device 12 will be referred to as a "server" and the robot 414 will be referred to as a "terminal."

[1547] Conventional child seat systems often fail to provide comfort or enjoyment for children during long car trips. In particular, they often fail to provide content tailored to a child's emotional state, leading to boredom or irritability. Furthermore, they offer limited information about destinations and activities, making it difficult for children to stay interested during the trip.

[1548] The specific processing by the specific processing unit 290 of the data processing device 12 in Application Example 2 is realized by the following means. In this invention, the server includes: means for the user to send commands by voice or text; means for the server to acquire specified content (music, story, dialogue data, etc.) from a database; means for the terminal to play or display the acquired content; means for the server to record the user's activities in a log; and means for analyzing the user's emotional state using emotion recognition technology and providing content accordingly. This makes it possible to provide appropriate content according to the user's emotional state, allowing children to spend a comfortable and enjoyable time even during long car trips.

[1549] A "means for users to send commands by voice or text" is a device or function that allows a user to send commands or requests to a system using voice or text input.

[1550] "Means for the server to retrieve specified content (music, story, dialogue data, etc.) from a database" refers to a method or device that allows the server to search for and retrieve specific content stored in a database.

[1551] The "means for the terminal to play or display the acquired content" refers to a device or function for the terminal to play or visually present the content received from the server.

[1552] "Means for the server to log user activity" refers to a mechanism that allows the server to record user operations and system operation status so that they can be checked later.

[1553] "Means for analyzing a user's emotional state using emotion recognition technology and providing content in accordance with that state" refers to technology or devices that grasp a user's emotional state by analyzing voice data and facial expression data, and select and provide content appropriate to that state.

[1554] This invention relates to a child car seat system for use in autonomous vehicles. In this system, a user sends commands using voice or text, a server retrieves specified content from a database, and a terminal plays or displays the retrieved content. Furthermore, emotion recognition technology is used to analyze the user's emotional state and provide content appropriate to the user's emotional state.

[1555] The system hardware configuration uses a smartphone or a head-mounted display. These devices include a microphone and speaker for audio input and output, and a display for video display. These devices communicate with a cloud server via the Internet.

[1556] The cloud server utilizes the following software and platforms:

[1557] Speech recognition technology: Google Cloud Speech-to-Text API

[1558] Emotion recognition technology: Microsoft Azure Emotion API

[1559] Content management and delivery: AWS Lambda, AWS RDS, and DynamoDB

[1560] Response generation: OpenAI's GPT-4

[1561] From the perspective of generating the system's programs, when a user sends a command via voice or text, the command is first analyzed locally via a smartphone or head-mounted display. The command is then sent to a cloud server, which retrieves appropriate content from a database based on the command. For example, if a user commands "sing a song," the server selects uplifting music content and sends it to the device, which then plays the music.

[1562] The process of analyzing the user's emotional state using emotion recognition technology also takes place on a cloud server. The user's voice and facial expression data are analyzed using Microsoft Azure's Emotion API, and the most appropriate content is selected based on that emotional state. For example, if a child is anxious, a reassuring story can be provided. For this reason, the emotion recognition engine can also monitor the user's emotional state in real time and record it in a log.

[1563] For example, if a child says, "Tell me about the zoo" while traveling in a family car, the cloud server retrieves information about the zoo from the database and sends it to the device. The device then uses a display device to present a map of the zoo and an animal quiz to the user.

[1564] Examples of prompts include:

[1565] Music Play Prompt: "Please play a happy song for the child who is feeling a bit down."

[1566] Picture Book Reading Prompt: "Read an engaging storybook to the child to keep their attention during the trip."

[1567] Informational prompt: "Provide interesting facts about the zoo and animals for the child's query about the zoo."

[1568] This allows children to have a comfortable and enjoyable time even during long car trips, while providing an environment where parents can concentrate on driving safely.

[1569] The flow of the specific processing in the application example 2 will be described with reference to FIG.

[1570] Step 1:

[1571] The user sends commands to the device by voice or text. The user's voice data or text data is collected by a smartphone or head-mounted display. The input is the user's voice command or text command, and the output is the voice data or text data.

[1572] Step 2:

[1573] The device converts voice data into text using voice recognition technology (Google Cloud Speech-to-Text API). The input is voice data and the output is text data. At this time, the device analyzes the voice command and sends it as text to the cloud server.

[1574] Step 3:

[1575] The server analyzes the received command text and retrieves the corresponding content (music, story, dialogue data, etc.) from the database. The input is the command text, and the output is the content data (music file, text file, audio file, etc.). The server searches the database for data based on the content ID corresponding to the command.

[1576] Step 4:

[1577] The server uses emotion recognition technology (Microsoft Azure's Emotion API) to analyze the user's voice data and facial expression data and evaluate the user's emotional state. The input is voice data and facial expression data, and the output is the user's emotional state (e.g., joy, sadness, excitement, etc.). Based on the results of this analysis, the server selects appropriate content.

[1578] Step 5:

[1579] The server selects appropriate content and sends it to the terminal. The input is the selected content data, and the output is the content data to be sent to the terminal. The server sends the data to the terminal through the network.

[1580] Step 6:

[1581] The device plays or displays the received content in an appropriate format. The input is the content data, and the output is a format that the user can view (e.g., playing music, displaying a story, etc.). The device provides the acquired content to the user.

[1582] Step 7:

[1583] The server logs all commands, responses, and emotional states. The input is data such as command text, content ID, and emotional state, and the output is records in a log file or database. The server stores this information for later review.

[1584] Step 8:

[1585] If the user issues an additional command, the process repeats, returning to step 1. The input is again the user's voice or text command, and the output is the provision of new content.

[1586] As a result, a system is realized that allows users to enjoy content comfortably and enjoyably even during long car trips.

[1587] The specific processing unit 290 transmits the result of the specific processing to the robot 414. In the robot 414, the control unit 46A causes the speaker 240 and the control target 443 to output the result of the specific processing. The microphone 238 acquires voice indicating a user input regarding the result of the specific processing. The control unit 46A transmits voice data indicating the user input acquired by the microphone 238 to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the voice data.

[1588] The data generation model 58 is a so-called generative AI (Artificial Intelligence). An example of the data generation model 58 is ChatGPT (Internet Search<URL: https: / / openai.com / blog / chatgpt> ), Gemini (Internet search <url: https: gemini.google.com ?hl="ja">) and other generation AIs. The data generation model 58 is obtained by performing deep learning on a neural network. A prompt including an instruction is input to the data generation model 58, and inference data such as voice data indicating voice, text data indicating text, and image data indicating an image is also input. The data generation model 58 performs inference on the input inference data in accordance with the instruction indicated by the prompt, and outputs the inference result in a data format such as voice data and text data. Here, inference refers to, for example, analysis, classification, prediction, and / or summarization.

[1589] In the above embodiment, an example in which the specific processing is performed by the data processing device 12 has been given, but the technology of the present disclosure is not limited to this, and the specific processing may be performed by the robot 414.

[1590] The emotion identification model 59 as an emotion engine may determine the user's emotion according to a specific mapping. Specifically, the emotion identification model 59 may determine the user's emotion according to an emotion map (see FIG. 9), which is a specific mapping. Similarly, the emotion identification model 59 may determine the robot's emotion, and the identification processing unit 290 may perform identification processing using the robot's emotion.

[1591] FIG. 9 is a diagram illustrating an emotion map 400 on which multiple emotions are mapped. In the emotion map 400, emotions are arranged in concentric circles radiating from the center. Emotions closer to the center of the concentric circles are more primitive. Emotions representing states and actions arising from a state of mind are arranged on the outer edges of the concentric circles. The concept of emotion includes both affect and mental states. Emotions generally generated from reactions occurring in the brain are arranged on the left side of the concentric circles. Emotions generally induced by situational judgment are arranged on the right side of the concentric circles. Emotions generally generated from reactions occurring in the brain and induced by situational judgment are arranged on the upper and lower sides of the concentric circles. Furthermore, the emotion of "pleasure" is arranged on the upper side of the concentric circles, and the emotion of "discomfort" is arranged on the lower side. In this way, in the emotion map 400, multiple emotions are mapped based on the structure by which emotions are generated, and emotions that tend to occur simultaneously are mapped close to each other.

[1592] These emotions are distributed in the 3 o'clock direction on emotion map 400, and typically fluctuate between relief and anxiety. In the right half of emotion map 400, situational awareness dominates over internal sensations, resulting in a sense of calm.

[1593] The inside of emotion map 400 represents what is going on in the mind, and the outside of emotion map 400 represents behavior, so the further you go outside emotion map 400, the more visible the emotions become (the more they are expressed in behavior).

[1594] Human emotions are based on various balances, such as posture and blood sugar levels. When these balances deviate from the ideal, a state of discomfort is indicated, and when they approach the ideal, a state of pleasure is indicated. Emotions can also be created for robots, automobiles, and motorcycles, based on various balances, such as posture and remaining battery life. When these balances deviate from the ideal, a state of discomfort is indicated, and when they approach the ideal, a state of pleasure is indicated. An emotion map can be generated, for example, based on Dr. Mitsuyoshi's emotion map (Research on Voice Emotion Recognition and Emotional Brain Physiological Signal Analysis Systems, Tokushima University, Doctoral Dissertation: https: / / ci.nii.ac.jp / naid / 500000375379). The left half of the emotion map lists emotions belonging to the "reaction" domain, where sensation is dominant. The right half of the emotion map lists emotions belonging to the "situation" domain, where situational awareness is dominant.

[1595] The emotion map defines two emotions that promote learning. One is a negative emotion on the situation side, around the middle of "repentance" or "reflection." In other words, this occurs when the robot experiences negative emotions such as "I never want to feel this way again" or "I don't want to be scolded again." The other is a positive emotion on the response side, around "desire." In other words, this occurs when the robot experiences positive feelings such as "I want more" or "I want to know more."

[1596] The emotion identification model 59 inputs user input into a pre-trained neural network, obtains emotion values ​​indicating each emotion shown in the emotion map 400, and determines the user's emotion. This neural network is pre-trained based on multiple pieces of training data that are combinations of user input and emotion values ​​indicating each emotion shown in the emotion map 400. Furthermore, this neural network is trained so that emotions that are located close to each other have similar values, as in the emotion map 900 shown in FIG. 10. FIG. 10 shows an example in which multiple emotions, "relieved," "calm," and "reassuring," have similar emotion values.

[1597] The system according to the present disclosure has been described above mainly with respect to the functions of the data processing device 12, but the system according to the present disclosure is not necessarily implemented on a server. The system according to the present disclosure may be implemented as a general information processing system. The present disclosure may be implemented, for example, as a software program running on a personal computer or an application running on a smartphone, etc. The method according to the present disclosure may be provided to users in the form of SaaS (Software as a Service).

[1598] In the above embodiment, an example was given in which the specific processing is performed by one computer 22, but the technology of the present disclosure is not limited to this, and the specific processing may be distributed and performed by a plurality of computers including the computer 22. For example, the data generation model 58 may be provided in an external device of the data processing device 12, and data may be generated in the external device in accordance with input data.

[1599] In the above embodiment, an example in which the specific processing program 56 is stored in the storage 32 has been described, but the technology of the present disclosure is not limited to this. For example, the specific processing program 56 may be stored in a portable, computer-readable, non-transitory storage medium such as a USB (Universal Serial Bus) memory. The specific processing program 56 stored in the non-transitory storage medium is installed in the computer 22 of the data processing device 12. The processor 28 executes the specific processing in accordance with the specific processing program 56.

[1600] Alternatively, the specific processing program 56 may be stored in a storage device such as a server connected to the data processing device 12 via the network 54, and the specific processing program 56 may be downloaded and installed on the computer 22 in response to a request from the data processing device 12.

[1601] It is not necessary to store all of the specific processing program 56 in a storage device such as a server connected to the data processing device 12 via the network 54, or to store all of the specific processing program 56 in the storage 32; only a portion of the specific processing program 56 may be stored.

[1602] The hardware resource for executing a specific process can be any of the following processors: An example of a processor is a CPU, which is a general-purpose processor that functions as a hardware resource for executing a specific process by executing software, i.e., a program. Another example of a processor is a dedicated electrical circuit, such as an FPGA (Field-Programmable Gate Array), a PLD (Programmable Logic Device), or an ASIC (Application Specific Integrated Circuit), which is a processor with a circuit configuration designed specifically for executing a specific process. Each processor has built-in or connected memory, and each processor uses the memory to execute the specific process.

[1603] The hardware resource that executes the specific processing may be configured with one of these various processors, or may be configured with a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, the hardware resource that executes the specific processing may be a single processor.

[1604] As an example of a system configured with a single processor, first, one processor is configured by combining one or more CPUs and software, and this processor functions as a hardware resource that executes a specific process. Second, there is a system that uses a processor that realizes the functions of an entire system including multiple hardware resources that execute a specific process on a single IC chip, as typified by SoC (System-on-a-chip). In this way, a specific process is realized using one or more of the above-mentioned various processors as hardware resources.

[1605] Furthermore, the hardware structure of these various processors can be, more specifically, an electric circuit that combines circuit elements such as semiconductor devices. The specific processing described above is merely an example. Therefore, it goes without saying that unnecessary steps may be deleted, new steps may be added, or the processing order may be rearranged, without departing from the spirit of the invention.

For example, the above description of the configuration, functions, actions, and effects is an explanation of an example of the configuration, functions, actions, and effects of the parts related to the technology of the present disclosure. Therefore, it goes without saying that unnecessary parts may be deleted, new elements may be added, or replacements may be made to the above-described description and illustrations within the scope of the gist of the technology of the present disclosure. Furthermore, to avoid confusion and facilitate understanding of the parts related to the technology of the present disclosure, the above-described description and illustrations omit explanations of common technical knowledge that do not require particular explanation to enable the implementation of the technology of the present disclosure.
