[0028] (Example 1) A dementia conversation support system according to an embodiment of the present invention is a system that engages in conversations with people with dementia to slow the progression of dementia. This system utilizes voice recognition technology with a smart speaker in the home to recognize what the person with dementia says, and a generation AI generates appropriate responses, stimulating cognitive function through conversation. It also has a function to record the content and frequency of conversations and monitor the progression of dementia. For example, if a smart speaker recognizes the voice of a person with dementia and asks, "What did you do today?", the person with dementia may respond, "I went for a walk." This utterance is analyzed using voice recognition technology, and the generation AI generates follow-up questions such as, "Where did you go?" and "Who did you go with?" This is designed to keep the conversation going. The content and frequency of conversations are also recorded to monitor the progression of dementia. For example, if the content of conversations gradually becomes shorter or the same topics are repeated, this may indicate the progression of dementia. This information is provided to medical professionals so that appropriate measures can be taken. This allows people with dementia to enjoy daily conversations and stimulate their cognitive function. It also makes it easier for family members and caregivers to understand the progression of dementia. For example, if a smart speaker asks, "What did you do today?" and a person with dementia replies, "I went for a walk," the details are recorded and can be checked later by family members or caregivers. In this way, by using a smart speaker and generative AI, it is possible to stimulate cognitive functions through conversations with people with dementia and slow the progression of dementia. This means that the dementia conversation support system can stimulate cognitive functions through conversations with people with dementia and slow the progression of dementia.
[0029] A dementia conversation support system according to an embodiment includes a voice recognition unit, a response generation unit, and a monitoring unit. The voice recognition unit recognizes the voice of a person with dementia. The voice of a person with dementia includes, but is not limited to, everyday conversations, questions, and responses. The voice recognition unit accurately captures the speech of the person with dementia using, for example, a voice recognition algorithm. The voice recognition unit can also improve recognition accuracy by removing background and environmental sounds using noise filtering technology. For example, when a person with dementia is watching television, the voice recognition unit can recognize speech by filtering out the sound of the television. When a person with dementia is out and about, the voice recognition unit can also recognize speech by filtering out the sound of wind and cars. Furthermore, when a person with dementia is with family, the voice recognition unit can recognize speech by filtering out the voices of other people. The response generation unit uses a generation AI to generate an appropriate response based on the speech recognized by the voice recognition unit. The response generation unit can analyze the speech of the person with dementia using, for example, natural language generation technology and generate an appropriate response. The response generation unit can also customize the content of the response based on the interests and concerns of the person with dementia. For example, if a person with dementia is interested in music, the response generation unit generates a response on a music-related topic. The response generation unit can also estimate the emotions of the person with dementia and adjust the way the response is expressed based on the emotion. For example, if a person with dementia is excited, the response generation unit generates a response in a calm tone. The monitoring unit records the content and frequency of conversations based on the responses generated by the response generation unit and monitors the progression of dementia. For example, if the content of conversations gradually becomes shorter or the same topics are repeated, the monitoring unit determines that the progression of dementia is progressing. The monitoring unit can also provide the recorded data to medical professionals so that appropriate measures can be taken. For example, the monitoring unit analyzes the content and frequency of conversations to predict the progression of dementia. As a result, the dementia conversation support system according to the embodiment can stimulate cognitive function through conversations with people with dementia and slow the progression of dementia.
[0030] The voice recognition unit can capture the speech of a person with dementia. The voice recognition unit, for example, uses a voice recognition algorithm to accurately capture the speech of a person with dementia. For example, when a person with dementia is asked, "What did you do today?", the voice recognition unit accurately recognizes the response, "I went for a walk." The voice recognition unit can also use noise filtering technology to remove background and environmental sounds to improve recognition accuracy. For example, when a person with dementia is watching television, the voice recognition unit can recognize the speech by filtering out the sound of the television. When a person with dementia is out and about, the voice recognition unit can also recognize the speech by filtering out the sound of the wind and cars. Furthermore, when a person with dementia is with family, the voice recognition unit can recognize the speech by filtering out the voices of other people. This makes it possible to accurately capture the speech of a person with dementia and generate an appropriate response. Some or all of the above-described processing in the voice recognition unit may be performed using, for example, AI, or without AI. For example, the voice recognition unit can input the speech of a person with dementia into AI and have the AI recognize the speech.
[0031] The response generation unit can analyze the utterances of the person with dementia and generate a response. The response generation unit can analyze the utterances of the person with dementia using, for example, natural language generation technology and generate an appropriate response. For example, if the person with dementia answers, "I went for a walk," the response generation unit generates additional questions such as, "Where did you go?" or "Who did you go with?" The response generation unit can also customize the content of the response based on the interests and concerns of the person with dementia. For example, if the person with dementia is interested in music, the response generation unit can generate a response on a music-related topic. The response generation unit can also estimate the emotions of the person with dementia and adjust the way the response is expressed based on the emotions. For example, if the person with dementia is excited, the response generation unit can generate a response in a calm tone. In this way, by analyzing the utterances of the person with dementia, an appropriate response can be generated to keep the conversation going. Some or all of the above-mentioned processing in the response generation unit can be performed using, for example, a generation AI. For example, the response generation unit can input the utterances of the person with dementia into a generation AI and have the generation AI generate a response.
[0032] The monitoring unit can record the content and frequency of conversations and monitor the progression of dementia. For example, the monitoring unit can determine that dementia is progressing if the content of conversations gradually becomes shorter or the same topics are repeated. The monitoring unit can also provide the recorded data to medical professionals so that appropriate measures can be taken. For example, the monitoring unit can analyze the content and frequency of conversations to predict the progression of dementia. In this way, the progression of dementia can be monitored by recording the content and frequency of conversations. Some or all of the above-mentioned processing in the monitoring unit can be performed using, for example, AI, or without AI. For example, the monitoring unit can input the content and frequency of conversations into AI and have the AI monitor the progression.
[0033] The monitoring unit can provide the recorded data to a medical professional. For example, the monitoring unit provides the recorded data to a medical professional so that an appropriate response can be taken. For example, the monitoring unit analyzes the content and frequency of conversations, predicts the progression of dementia, and provides the information to a medical professional. In this way, by providing the recorded data to a medical professional, an appropriate response can be taken. Some or all of the above-described processing in the monitoring unit may be performed using, for example, AI, or may be performed without using AI. For example, the monitoring unit can input the recorded data to AI and have the AI provide the data.
[0034] The voice recognition unit can analyze the past speech history of the person with dementia and select a voice recognition algorithm. For example, the voice recognition unit selects an algorithm that prioritizes recognition of words and phrases frequently used by the person with dementia in the past. The voice recognition unit can also analyze the speech patterns of the person with dementia and select a voice recognition algorithm suitable for a specific time period. Furthermore, the voice recognition unit can select the optimal voice recognition algorithm based on the speech speed and volume of the person with dementia. In this way, by analyzing the past speech history, the optimal voice recognition algorithm can be selected and recognition accuracy can be improved. Some or all of the above-mentioned processing in the voice recognition unit may be performed using, for example, AI, or may be performed without using AI. For example, the voice recognition unit can input the past speech history into AI and have the AI select the algorithm.
[0035] The voice recognition unit can improve recognition accuracy by filtering background sounds and environmental sounds during voice recognition. For example, when a person with dementia is watching television, the voice recognition unit recognizes speech by filtering out television sounds. Furthermore, when a person with dementia is out and about, the voice recognition unit can also recognize speech by filtering out wind sounds and car sounds. Furthermore, when a person with dementia is with family, the voice recognition unit can also recognize speech by filtering out other people's voices. In this way, by filtering out background sounds and environmental sounds, recognition accuracy can be improved. Some or all of the above-described processing in the voice recognition unit may be performed using, for example, AI, or may be performed without using AI. For example, the voice recognition unit can input data on background sounds and environmental sounds into AI and have the AI perform the filtering.
[0036] During speech recognition, the speech recognition unit can prioritize recognition of highly relevant utterances based on the geographical location information of the person with dementia. For example, if the person with dementia is at home, the speech recognition unit can prioritize recognition of utterances related to the home. Furthermore, if the person with dementia is in a park, the speech recognition unit can also prioritize recognition of utterances related to the park. Furthermore, if the person with dementia is in a hospital, the speech recognition unit can also prioritize recognition of utterances related to the hospital. In this way, by taking geographical location information into consideration, it is possible to prioritize recognition of highly relevant utterances and generate an appropriate response. Some or all of the above-described processing in the speech recognition unit may be performed, for example, using AI, or may be performed without using AI. For example, the speech recognition unit can input geographical location information to AI and have the AI perform priority recognition of utterances.
[0037] During voice recognition, the voice recognition unit can analyze the social media activities of the person with dementia and recognize relevant comments. For example, the voice recognition unit prioritizes recognition of words and phrases frequently used by the person with dementia on social media. The voice recognition unit can also analyze the content of the person with dementia's social media posts and recognize relevant comments. Furthermore, the voice recognition unit can prioritize recognition of the names and topics of people with whom the person with dementia interacts on social media. This makes it possible to recognize relevant comments and generate appropriate responses by analyzing social media activities. Some or all of the above-mentioned processing in the voice recognition unit may be performed using, for example, AI, or may be performed without using AI. For example, the voice recognition unit can input data on social media activities into AI and have the AI recognize the comments.
[0038] When generating a response, the response generation unit can customize the content of the response based on the interests and concerns of the person with dementia. For example, if the person with dementia is interested in music, the response generation unit can generate a response on a music-related topic. Furthermore, if the person with dementia is interested in cooking, the response generation unit can also generate a response on a cooking-related topic. Furthermore, if the person with dementia is interested in sports, the response generation unit can also generate a response on a sports-related topic. This allows the content of the response to be customized based on the interests and concerns, thereby keeping the conversation going. Some or all of the above-mentioned processing in the response generation unit may be performed, for example, using a generation AI, or may be performed without using a generation AI. For example, the response generation unit can input data on the interests and concerns of the person with dementia into the generation AI and have the generation AI customize the response.
[0039] When generating a response, the response generation unit can generate a consistent response based on the past conversation history of the person with dementia. The response generation unit generates a relevant response based on, for example, content that the person with dementia has spoken in the past. The response generation unit can also generate a consistent response on a specific topic from the past conversation history of the person with dementia. Furthermore, the response generation unit can generate a response based on topics that the person with dementia has shown interest in in the past. In this way, by referring to the past conversation history, a consistent response can be generated and the conversation can be continued without interruption. Some or all of the above-mentioned processing in the response generation unit may be performed using, for example, a generation AI, or may be performed without using a generation AI. For example, the response generation unit can input the past conversation history into the generation AI and cause the generation AI to generate a consistent response.
[0040] When generating responses, the response generation unit can determine the order of responses based on the frequency of utterances made by the person with dementia. For example, if the person with dementia speaks frequently, the response generation unit sets a high priority for the response. The response generation unit can also set a low priority for the response if the person with dementia does not speak much. Furthermore, the response generation unit can dynamically adjust the priority of responses according to the frequency of utterances made by the person with dementia. This makes it possible to generate appropriate responses by determining the priority of responses based on the frequency of utterances. Some or all of the above-mentioned processing in the response generation unit may be performed using, or without, a generation AI. For example, the response generation unit can input utterance frequency data into the generation AI and have the generation AI determine the priority of responses.
[0041] When generating a response, the response generation unit can adjust the content of the response based on the medical data of the person with dementia. For example, the response generation unit generates a response according to the health condition from the medical data of the person with dementia. The response generation unit can also generate an appropriate response by referring to the medication information of the person with dementia. Furthermore, the response generation unit can adjust the content of the response based on the diagnosis data of the person with dementia. This makes it possible to generate an appropriate response by referring to related medical data. Some or all of the above-mentioned processing in the response generation unit may be performed using, or without, a generation AI. For example, the response generation unit can input medical data into the generation AI and have the generation AI adjust the content of the response.
[0042] During monitoring, the monitoring unit can predict the progression of dementia by analyzing the content and frequency of conversations. For example, if the content of conversations gradually becomes shorter, the monitoring unit can predict that the progression of dementia is progressing. The monitoring unit can also predict that the progression of dementia is progressing if the same topic is repeated. Furthermore, the monitoring unit can predict that the progression of dementia is progressing if the frequency of conversations decreases. In this way, the progression of dementia can be predicted by analyzing the content and frequency of conversations. Some or all of the above-mentioned processing in the monitoring unit may be performed, for example, using AI, or may be performed without using AI. For example, the monitoring unit can input conversation data into AI and have the AI execute a progress prediction.
[0043] During monitoring, the monitoring unit can evaluate the progress of the person with dementia based on the lifestyle habit data. The monitoring unit can evaluate the progress by referring to, for example, the sleep pattern of the person with dementia. The monitoring unit can also evaluate the progress by referring to the eating pattern of the person with dementia. The monitoring unit can also evaluate the progress by referring to the exercise pattern of the person with dementia. This makes it possible to more accurately evaluate the progress of dementia by referring to the lifestyle habit data. Some or all of the above-mentioned processing in the monitoring unit may be performed using, for example, AI, or may be performed without using AI. For example, the monitoring unit can input the lifestyle habit data into AI and have the AI evaluate the progress.
[0044] During monitoring, the monitoring unit can evaluate the progress of the person with dementia based on the geographical location information of the person with dementia. For example, if the person with dementia is at home, the monitoring unit can evaluate the progress by referring to their behavioral patterns at home. Furthermore, if the person with dementia is out and about, the monitoring unit can evaluate the progress by referring to their behavioral patterns while out and about. Furthermore, if the person with dementia is in a hospital, the monitoring unit can evaluate the progress by referring to their behavioral patterns at the hospital. In this way, by taking the geographical location information into consideration, the progress of dementia can be more accurately evaluated. Some or all of the above-described processing in the monitoring unit may be performed using, for example, AI, or may be performed without using AI. For example, the monitoring unit can input the geographical location information into AI and have the AI evaluate the progress.
[0045] During monitoring, the monitoring unit can analyze the social media activity of the person with dementia to evaluate their progress. For example, the monitoring unit can evaluate their progress by referring to the frequency of posts on social media by the person with dementia. The monitoring unit can also evaluate their progress by referring to the interaction patterns of the person with dementia on social media. The monitoring unit can also evaluate their progress by referring to the language used by the person with dementia on social media. This allows for a more accurate evaluation of the progression of dementia by analyzing social media activity. Some or all of the above-mentioned processing in the monitoring unit may be performed using, for example, AI, or may be performed without using AI. For example, the monitoring unit can input social media activity data into AI and have the AI evaluate their progress.

For example, if the user has not been exercising recently, the system can generate a question such as "Have you been exercising recently?" to encourage the user to exercise. The system can also provide topics related to healthy eating based on the user's diet. Furthermore, the system can check whether the user is getting enough rest based on their sleep patterns and suggest relaxation methods if necessary.
[0053] The processing flow of the first embodiment will be briefly explained below.
[0054] Step 1: The speech recognition unit recognizes the speech of the person with dementia. Speech from the person with dementia includes everyday conversations, questions, and responses. The speech recognition unit uses a speech recognition algorithm to accurately capture what is being said and noise filtering technology to remove background and environmental sounds. For example, it filters out the sound of the television, wind, cars, and other people's voices to recognize what is being said. Step 2: The response generation unit generates an appropriate response based on the speech recognized by the speech recognition unit. It analyzes the speech using generative AI and natural language generation technology, and customizes the response based on the interests and concerns of the person with dementia. It also estimates the emotions of the person with dementia and adjusts the way the response is expressed based on those emotions. Step 3: The monitoring unit records the content and frequency of conversations based on the responses generated by the response generation unit, and monitors the progression of dementia. If the content of conversations becomes shorter or the same topics are repeated, it is determined that the dementia is progressing. The recorded data is also provided to medical professionals so that appropriate measures can be taken.
[0055] (Example 2) A dementia conversation support system according to an embodiment of the present invention is a system that engages in conversations with people with dementia to slow the progression of dementia. This system utilizes voice recognition technology with a smart speaker in the home to recognize what the person with dementia says, and a generation AI generates appropriate responses, stimulating cognitive function through conversation. It also has a function to record the content and frequency of conversations and monitor the progression of dementia. For example, if a smart speaker recognizes the voice of a person with dementia and asks, "What did you do today?", the person with dementia may respond, "I went for a walk." This utterance is analyzed using voice recognition technology, and the generation AI generates follow-up questions such as, "Where did you go?" and "Who did you go with?" This is designed to keep the conversation going. The content and frequency of conversations are also recorded to monitor the progression of dementia. For example, if the content of conversations gradually becomes shorter or the same topics are repeated, this may indicate the progression of dementia. This information is provided to medical professionals so that appropriate measures can be taken. This allows people with dementia to enjoy daily conversations and stimulate their cognitive function. It also makes it easier for family members and caregivers to understand the progression of dementia. For example, if a smart speaker asks, "What did you do today?" and a person with dementia replies, "I went for a walk," the details are recorded and can be checked later by family members or caregivers. In this way, by using a smart speaker and generative AI, it is possible to stimulate cognitive functions through conversations with people with dementia and slow the progression of dementia. This means that the dementia conversation support system can stimulate cognitive functions through conversations with people with dementia and slow the progression of dementia.
[0056] A dementia conversation support system according to an embodiment includes a voice recognition unit, a response generation unit, and a monitoring unit. The voice recognition unit recognizes the voice of a person with dementia. The voice of a person with dementia includes, but is not limited to, everyday conversations, questions, and responses. The voice recognition unit accurately captures the speech of the person with dementia using, for example, a voice recognition algorithm. The voice recognition unit can also improve recognition accuracy by removing background and environmental sounds using noise filtering technology. For example, when a person with dementia is watching television, the voice recognition unit can recognize speech by filtering out the sound of the television. When a person with dementia is out and about, the voice recognition unit can also recognize speech by filtering out the sound of wind and cars. Furthermore, when a person with dementia is with family, the voice recognition unit can recognize speech by filtering out the voices of other people. The response generation unit uses a generation AI to generate an appropriate response based on the speech recognized by the voice recognition unit. The response generation unit can analyze the speech of the person with dementia using, for example, natural language generation technology and generate an appropriate response. The response generation unit can also customize the content of the response based on the interests and concerns of the person with dementia. For example, if a person with dementia is interested in music, the response generation unit generates a response on a music-related topic. The response generation unit can also estimate the emotions of the person with dementia and adjust the way the response is expressed based on the emotion. For example, if a person with dementia is excited, the response generation unit generates a response in a calm tone. The monitoring unit records the content and frequency of conversations based on the responses generated by the response generation unit and monitors the progression of dementia. For example, if the content of conversations gradually becomes shorter or the same topics are repeated, the monitoring unit determines that the progression of dementia is progressing. The monitoring unit can also provide the recorded data to medical professionals so that appropriate measures can be taken. For example, the monitoring unit analyzes the content and frequency of conversations to predict the progression of dementia. As a result, the dementia conversation support system according to the embodiment can stimulate cognitive function through conversations with people with dementia and slow the progression of dementia.
[0057] The voice recognition unit can capture the speech of a person with dementia.

For example, the monitoring unit can input the recorded data to AI and have the AI provide the data.
[0061] The speech recognition unit can estimate the emotions of the person with dementia and adjust the accuracy of speech recognition based on the emotions. For example, if the person with dementia is excited, the speech recognition unit can reduce false recognitions by lowering the sensitivity of speech recognition. Furthermore, if the person with dementia is calm, the speech recognition unit can increase the sensitivity of speech recognition to capture even small details. Furthermore, if the person with dementia is tired, the speech recognition unit can set the sensitivity of speech recognition to a medium level to allow the person with dementia to continue the conversation without strain. This adjusts the accuracy of speech recognition according to the emotions of the person with dementia, reducing false recognitions and allowing the conversation to continue appropriately. Emotion estimation is achieved using an emotion estimation function, for example, using an emotion engine or generative AI. Generative AI includes, but is not limited to, text generation AI (e.g., LLM) and multimodal generation AI. Some or all of the above-described processing in the speech recognition unit may be performed using AI, or without AI.

Furthermore, the system can check whether the user is getting enough rest based on their sleep patterns and suggest relaxation methods if necessary.
[0089] The dementia conversation support system can further include an emotion frequency adjustment unit that estimates the user's emotion and adjusts the frequency of conversation based on the estimated emotion. For example, if the user is excited, the emotion frequency adjustment unit reduces the frequency of conversation to calm the user. Also, if the user is relaxed, the emotion frequency adjustment unit can increase the frequency of conversation to actively communicate. Furthermore, if the user is tired, the frequency of conversation can be set to a medium level so that the user can continue the conversation without straining themselves. In this way, more effective conversation support can be achieved by adjusting the frequency of conversation according to the user's emotion.
[0090] The processing flow of the second embodiment will be briefly explained below.
[0091] Step 1: The speech recognition unit recognizes the speech of the person with dementia. Speech from the person with dementia includes everyday conversations, questions, and responses. The speech recognition unit uses a speech recognition algorithm to accurately capture what is being said and noise filtering technology to remove background and environmental sounds. For example, it filters out the sound of the television, wind, cars, and other people's voices to recognize what is being said. Step 2: The response generation unit generates an appropriate response based on the speech recognized by the speech recognition unit. It analyzes the speech using generative AI and natural language generation technology, and customizes the response based on the interests and concerns of the person with dementia. It also estimates the emotions of the person with dementia and adjusts the way the response is expressed based on those emotions. Step 3: The monitoring unit records the content and frequency of conversations based on the responses generated by the response generation unit, and monitors the progression of dementia. If the content of conversations becomes shorter or the same topics are repeated, it is determined that the dementia is progressing. The recorded data is also provided to medical professionals so that appropriate measures can be taken.

The AI may also be an AI agent. When the processing of each of the above-mentioned parts is performed by an AI, the processing may be performed in part or entirely by the AI, but is not limited to these examples. The processing performed by an AI including the generative AI may be replaced with rule-based processing, and rule-based processing may be replaced with processing performed by an AI including the generative AI.

Emotions representing states and behaviors arising from a state of mind are arranged on the outer edges of the concentric circles. The concept of emotion encompasses both emotions 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.
[0147] 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.
[0148] 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).
[0149] 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 expressed, and when they approach the ideal, a state of pleasure is expressed. Emotions can also be created for robots, cars, 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 expressed, and when they approach the ideal, a state of pleasure is expressed. An emotion map can be generated, for example, based on Dr. Mitsuyoshi's emotion map (Research on speech emotion recognition and brain physiological signal analysis systems for emotions, Tokushima University, doctoral dissertation: https: / / ci.nii.ac.jp / naid / 500000375379). The left half of the emotion map lists emotions belonging to the area called "reaction," where sensation is dominant. The right half of the emotion map lists emotions belonging to the area called "situation," where situational awareness is dominant.
[0150] 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."
[0151] 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.
[0152] In the above embodiment, an example was given in which a specific process is performed by one computer 22, but the technology disclosed herein is not limited to this, and distributed processing of the specific process may be performed by multiple computers including computer 22.
[0153] 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.
[0154] 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.
[0155] 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.
[0156] The hardware resource for executing a specific process can be any of the following types of processors: A processor, for example, 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. A processor also includes 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.
[0157] The hardware resource that executes the specific process 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 process may be a single processor.
[0158] 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.
[0159] 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.
[0160] In the above example, the first to fourth embodiments have been described separately, but some or all of these embodiments may be combined. The smart device 14, smart glasses 214, headset terminal 314, and robot 414 are merely examples, and they may be combined, or other devices may be used. In the above example, the first and second embodiments have been described separately, but they may be combined.
[0161] The above-described description and illustrations are a detailed explanation of the parts related to the technology of the present disclosure and are merely an example of the technology of the present disclosure. 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.
