Description

Electronic device and method of controlling the same

[0001] The present disclosure relates to an electronic device and a control method thereof, and more particularly, to an electronic device providing a chat service to which a filtering function is applied and a control method thereof.

[0002] When viewing content, chat services may be provided. For example, while watching a sports game, an online chat service may be provided, allowing multiple users to converse about common interests. The display device may provide the chat service alongside or separately from the content.

[0003] A chat service can be a service where an unspecified number of users watching content can converse together. In online spaces where unspecified numbers of people converse, filtering functions can be applied to conversations. Filtering functions can be applied to prevent profanity and swearing.

[0004] However, personalized chat services, rather than open spaces where anyone can converse, may be necessary. If personalized chat services also face the same filtering requirements as open spaces, users could become dissatisfied.

[0005] If the filtering function is removed from the personalized chat service, there is a problem that indiscriminate profanity and other content will be displayed without filtering.

[0006] The present disclosure is designed to improve the above-described problem, and the purpose of the present disclosure is to provide an electronic device and a control method thereof that provide a filtering function with different filtering levels by distinguishing between a public chat service and a private chat service.

[0063] An embodiment of the present disclosure will be described in more detail with reference to the attached drawings below.

[0064] FIG. 1 is a drawing for explaining a chat service according to one embodiment.

[0065] Referring to FIG. 1, an electronic device (100) can provide content. The content may include at least one of an image or video. The electronic device (100) can provide a chat service along with the content. The chat service may represent a conversation service. The chat service may include a service for at least one user to conduct a conversation. The chat service may utilize different methods.

[0066] In one embodiment, the chat service may be a service that displays users' conversations in text form. A specific user's conversation may be displayed in text form.

[0067] In one embodiment, the chat service may be a service that provides users' conversations in audio format. Users' conversations may be provided through video images and voice audio.

[0068] A chat service may include a service that provides chat rooms.

[0069] The user's interaction may be at least one of voice input and manipulation input. Voice input may represent input spoken by the user. Manipulation input may represent input operated via a manipulation device such as a keyboard or remote control.

[0070] An electronic device (100) may provide a screen (10) related to a chat service. The electronic device (100) may separately provide a UI representing the chat service along with content. The UI representing the chat service may be displayed as a single screen along with the content.

[0071] There may be various ways in which the UI representing the chat service is displayed.

[0072] According to one embodiment, the electronic device (100) may display content in a first area of ​​the entire area of ​​the display (140) of the electronic device (100) and display a chat service in a second area (different from the first area).

[0073] According to one embodiment, the electronic device (100) may display content on the entire area of ​​the display (140) of the electronic device (100) and display a chat service in a pop-up form on a third area (a specific area, which may be changed) among the entire area.

[0074] The electronic device (100) may provide a filtering function when providing a chat service. The filtering function may refer to performing a filtering operation on a user's conversation input. The filtering function may include an operation for processing input pre-specified by the user.

[0075] The filtering function may include at least one of the following: the ability to not display certain words or certain sentences, the ability to hide certain words or certain sentences, and the ability to change (or replace) certain words or certain sentences.

[0076] For example, assume that user A inputs “go to hell” on screen (10) of Fig. 1. A filtering function may determine that “go to hell” is inappropriate. The electronic device (100) may display “go to hxxx” instead of “go to hell” through the filtering function. The electronic device (100) may provide a chat service through a function that obscures part of the user input.

[0077] FIG. 2 is a block diagram illustrating an electronic device (100) according to one embodiment.

[0078] Referring to FIG. 2, the electronic device (100) may include at least one of a memory (110), at least one processor (120), or a display (140).

[0079] The electronic device (100) may be an electronic whiteboard, TV, desktop PC, laptop, smartphone, tablet PC, server, etc. The above-described examples are merely examples for explaining the electronic device and are not necessarily limited to the above-described devices.

[0080] The memory (110) can store the first account of the electronic device (100). The first account of the electronic device (100) can represent an account accessed from the electronic device (100) or one of the accounts accessed from the electronic device (100). The first account can be described as an account associated with the electronic device (100).

[0081] The display (140) can display a screen including at least one of content, a public chat service, or a private chat service.

[0082] At least one processor (120) is connected to at least one of a memory (110) or a display (140) and can execute various control commands.

[0083] At least one processor (120) can perform overall control operations of the electronic device (100). At least one processor (120) can perform a function of controlling overall operations of the electronic device (100).

[0084] At least one processor (120) can control the display (140) to display a first screen including content and a public chat service to which a first filtering level is applied.

[0085] At least one processor (120) can display specific content on the display (140). At least one processor (120) can display a public chat service on the display (140) along with the specific content. The public chat service may be a service in which multiple users viewing the content converse with each other. The public chat service may refer to a service in which an unspecified number of users viewing the content participate.

[0086] Public chat services may be subject to a first-level filtering level. The filtering level may indicate the degree of filtering performed during the filtering function. The filtering function may filter user input (conversations) entered into the chat service.

[0087] The filtering function may include at least one of the following: a function to remove (delete) at least a portion of the user input, a function to obscure at least a portion of the user input, and a function to replace at least a portion of the user input. Specific operations related thereto are described in FIG. 15.

[0088] At least one processor (120) can control the display (140) to display a second account identified based on conversation history information of the first account when a request for a private chat service is received.

[0089] Unlike public chat services, private chat services may be chat services that only allow users to participate under certain conditions.

[0090] For example, a specific condition might include an intimacy level exceeding a threshold. A private chat service might be available only to users whose mutual intimacy level exceeds a threshold.

[0091] For example, a specific condition may include a user level above a threshold. A private chat service may be available only to users with a user level (e.g., paid / free level in a subscription system) above a threshold.

[0092] For example, a specific condition might include a direct invitation from a specific user. A private chat service might be available only to users directly invited (or selected) by a specific user (host).

[0093] Conversation history information may include information related to the chat service a specific account participated in. Information related to the chat service may include at least one of the following: the chat service name, participants, conversation partners, number of conversations, and conversation content.

[0094] The content of the conversation can be used to determine whether a common topic was entered (or spoken) or whether the other person's name was mentioned.

[0095] The second account may be an account identified to use the private chat service together based on conversation history information.

[0096] The second account may be identified based on intimacy obtained from conversation history information. Intimacy may refer to information indicating the frequency of conversations between multiple users. Intimacy may be expressed in terms such as the degree of interaction or the degree of relationship.

[0097] When specific events are identified based on conversation history information, the intimacy between users can be identified as relatively high.

[0098] A particular event may be an event that occurs between multiple users of the comparison target.

[0099] A specific event may include at least one of an event using the same chat service, an event using direct chat, an event entering a chat within a threshold time from a specific time, an event entering a specific word, and an event in which a specific behavioral pattern (e.g., the order of content viewed, the order of emoticon use, the order of application execution, etc.) is identified.

[0100] At least one processor (120) may provide a private chat service based on a second filtering level obtained based on the intimacy between a first account of the electronic device (100) and a second account of the external device (200). The second filtering level may be different from the first filtering level. The second filtering level may be lower than the first filtering level.

[0101] Public and private chat services may be managed with different filtering levels. Because public chat services are used by an unspecified number of users, they may be subject to stricter filtering levels than private chat services.

[0102] The second account may be one of multiple accounts using the public chat service. The second account may be at least one account selected from among multiple accounts participating in the public chat service. Accounts that do not participate in the public chat service associated with a specific content may not be able to participate in the private chat service. This is because the private chat service is mapped to the content or public chat service. A related explanation is provided in Figure 4.

[0103] The second account may be one of multiple accounts using the public chat service, with an affinity level exceeding a threshold with the first account. This affinity level may be determined based on the first account's conversation history.

[0104] Accounts participating in private chat services can be automatically identified. The second account may be an account with a threshold level of intimacy with the first account requesting the public chat service. The second account may be a concept that includes at least one account.

[0105] At least one processor (120) may receive a first user input requesting a private chat service. At least one processor (120) may control the display (140) to display a second screen including a candidate account whose affinity with the first account among multiple accounts using the public chat service is greater than a threshold value.

[0106] Accounts that have a closeness level exceeding a threshold with the first account requesting the private chat service can be identified as candidate accounts. The second screen may display the candidate accounts. Users of the first account can select the account they wish to use the private chat service with from among the candidate accounts through the second screen.

[0107] At least one processor (120) may receive a second user input, via a second screen, for selecting at least one of the candidate accounts as a target account. Specific account selection operations related to the candidate account and target account are described in FIG. 5.

[0108] Upon receiving a second user input, at least one processor (120) may provide a private chat service based on a response from an external device corresponding to the target account. A detailed description of the response is provided in S1270 to S1280 of FIG. 12.

[0109] At least one processor (120) can control the display (140) to display a third screen including a private chat service in which the first account and the second account participate based on a response to participate in the private chat service.

[0110] At least one processor (120) may receive a third user input for a conversation in a private chat service. Upon receiving the third user input, the at least one processor (120) may control the display (140) to display a fourth screen containing information regarding the results of a filtering function performed based on the second filtering level.

[0111] Third-party user input may include conversations entered into a private chat service. For example, third-party user input may include information entered through a user's actions (e.g., typing). For example, third-party user input may include information entered through a user's speech (e.g., voice).

[0112] When a third user input including a preset target text is received, at least one processor (120) can control the display (140) to display a fourth screen including result information in which the target text is changed to a preset alternative text.

[0113] Alternative text may be text obtained based on metadata of the content.

[0114] Content metadata may include data related to the content. This data may include the content name, content type, content provision time, content summary information, and content extraction information.

[0115] The target text may contain at least one of the following: prohibited words, profanity, vulgarity, insults, or slander.

[0116] The text may contain one or more words. If the text contains multiple words, the text may correspond to the target text in various embodiments.

[0117] For example, the text may contain at least one preset word that is to be judged (or determined or identified) as the target text.

[0118] For example, a text may not contain a predetermined word to be determined as a target text. A text may be determined as a target text based on a combination of multiple words contained within the text. The text may include a first word and a second word. The first and second words may not each be prohibited words, profanity, or the like. However, the combination of the first and second words may be prohibited words, profanity, or the like.

[0119] The above-described operations may be performed in an electronic device (100) or a server (300). The electronic device (100) may be a device including a display (140), and the server (300) may be a device providing a chat service.

[0120] According to various embodiments, the electronic device (100) may directly perform operations related to a chat service in the form of an on-device.
