Description

Technical Field

[0001] This disclosure relates to a content evaluation method for an instant messaging application, specifically, to a method and system for sharing a screen associated with a user account in a chat window of an instant messaging application that includes a user account, and receiving evaluations of at least one piece of content contained in the shared screen from at least one user account included in the chat window. Background Technology

[0002] With the development of mobile devices such as smartphones and the internet, instant messaging applications have become widely used. Users of these applications can naturally communicate and share opinions with each other in their daily lives. Such users may find themselves at crossroads in various aspects of their lives, and in order to make informed choices, they may want to receive opinions from acquaintances regarding their options. Therefore, users can use instant messaging applications to request and receive evaluations or opinions from other users or acquaintances about the options they are interested in and want to choose.

[0003] In existing instant messaging applications, if a member in a chat group wants to share content they want to comment on, they need to leave the chat window, operate another application or communication application, and share this content as an image or file to the chat window. Therefore, after a user imports content intended for commenting from outside the chat window and shares it, it's inconvenient to need to share new content from outside the chat window again to add more commenters. In this environment, the number of content that can receive comments may be limited. Furthermore, users of such instant messaging applications only convey opinions through text or voice, thus limiting the effective transmission of opinions from multiple users. Additionally, using the poll list generation service provided in existing instant messaging applications requires users to manually input the poll list, which is inconvenient. Therefore, when using services provided by existing instant messaging applications to receive comments on content that a user is interested in, the inconvenience increases as the number of people or the amount of content in the chat window increases.

Different numbers of user terminals 220_1, 220_2, and 220_3 may also be configured to communicate with the content evaluation system 200 via network 210.

[0076] The content evaluation system 200 can provide a screen sharing service between user terminals 220_1, 220_2, and 220_3 running an instant messaging application. According to one embodiment, the content evaluation system 200 can receive screens from more than one user through a VoIP (Voice over Internet Protocol) channel with user terminals 220_1, 220_2, and 220_3, and share them in real time through the instant messaging application. For example, the content evaluation system 200 can share video captured by at least some of the user terminals 220_1, 220_2, and 220_3 during a video call service provided by the instant messaging application. The video call service can be provided through the chat window of the instant messaging application. As another example, the content evaluation system 200 can share a program or application running on one of the user terminals 220_1, 220_2, and 220_3 through the chat window of the instant messaging application. According to other embodiments, screens received in real time from at least some of the user terminals 220_1, 220_2, and 220_3 via a broadcast channel can be shared in the chat window. The broadcast channel can be generated in any bidirectional communication manner. The content evaluation system 200 can output a shared screen to user terminals 220_1, 220_2, and 220_3 running instant messaging applications.

[0077] The content evaluation system 200 can be configured to receive input from user terminals 220_1, 220_2, and 220_3 to display a selection, which is a selection of a portion corresponding to at least one piece of content contained in a screen shared via a chat window of an instant messaging application. For example, when user terminal 220_1 shares its own screen and wants to receive evaluations from other user terminals 220_2 and 220_3 in the chat window for at least one product item among multiple product items contained in the shared screen, user terminal 220_1 can select at least one product item. In response to the input to display a selection for at least one piece of content, at least one piece of content can be extracted, and the extracted at least one piece of content can be provided to the content evaluation system 200 via network 210.

According to one embodiment, the shared screen can be configured to be displayed on at least a portion of the display of user terminal 220 via input / output interface 318. For example, the shared screen can be output to the background, top, side, or bottom of the chat window displayed on the display. Furthermore, while displaying the shared screen in the chat window, processor 314 can provide an interface enabling the user of user terminal 220 to interact with other users participating in the chat window or to select and / or evaluate content contained in the shared screen.

[0094] Processor 314 can receive at least one piece of content selected by other user terminals from content evaluation system 200, and output at least one piece of content through a chat window of an instant messaging application that can be displayed on a displayable output device. According to one embodiment, whenever content is selected on a shared screen, processor 314 can receive the selected content through communication module 316 and output it through a chat window displayed on the monitor. In other embodiments, when multiple pieces of content are selected on a shared screen, processor 314 can receive all the selected content and output them together.

[0095] Processor 314 can control input / output interface 318 to display at least one received content in at least a portion of the chat window of an instant messaging application. For example, a user of user terminal 220 can press or click a button or link (e.g., a shopping cart icon, rating (vote) icon, etc.) displayed in the chat window to display at least one piece of content on the screen. At least one piece of content can be received from content rating system 200 as a rating candidate list and / or a final rating candidate list, and thus shared through the chat window displayed on the screen. This shared rating candidate list and / or final rating candidate list is accessed in real time by multiple user accounts included in the chat window for decision-making or rating of the content.

[0096] According to one embodiment, the processor 314 receives not only at least one selected piece of content from the content evaluation system 200, but also information related to the at least one piece of content, which can then be output through a chat window of an instant messaging application displayed on a displayable output device. For example, when the at least one piece of content is a first piece of content, the first piece of content and information related to the first piece of content can be displayed together in the chat window. Additionally, when the at least one piece of content is selected together with the first piece of content in a shared screen, or is included as second content in a subsequently shared screen, the second piece of content and information related to the second piece of content can be output together to the chat window displayed on the display.

[0097] Processor 314 can output a list of multiple pieces of content selected from content evaluation system 200 in various formats via a chat window of an instant messaging application displayed on a screen. According to one embodiment, processor 314 can receive the list of selected content in a majority voting format where multiple users can respond.

[0098] Processor 314 can receive evaluations of at least one piece of content from content evaluation system 200 and display the received evaluations via a displayable device. According to one embodiment, processor 314 can receive voting results for multiple pieces of content included in a candidate list of evaluations shared in a chat window and share the received voting results via the chat window. In other embodiments, processor 314 can receive an evaluation record including at least one piece of content evaluated so far and the evaluations of at least one piece of content, and share the received evaluation record via the chat window.

[0099] The processor 334 of the content evaluation system 200 can be configured to manage, process, and / or store information and / or data received from multiple user terminals, including user terminal 220, and / or multiple external systems. The information and / or data processed by the processor 334 can be provided to user terminal 220 via communication module 336. For example, the processed information and / or data can be provided to user terminal 220 in real time or provided retroactively in recorded form. For example, the processor 334 can receive a screen sharing request from user terminal 220 to provide the screen of user terminal 220 to the terminals of other user accounts in the chat window, enabling the sharing of the screen executed in user terminal 220 within the chat window.

[0100] According to one embodiment, processor 334 can collect information related to at least one selected content based on a shared screen received from user terminal 220. The content-related information can be any information that displays the content or identifies the content, such as content images, content names, sales locations, prices, etc., but is not limited thereto. According to one embodiment, processor 334 can receive an image including at least one piece of content, identify text displaying or describing the at least one piece of content from the received image, and select it. According to other embodiments, processor 334 can receive at least one piece of content and collect information related to the at least one piece of content on a network. The information thus collected can be associated with the at least one piece of content and provided to user terminal 220. Alternatively, information related to at least one piece of content can be collected by processor 314 through selection on a shared screen or retrieval on a network.

[0101] Processor 334 may be configured to generate a list including at least one selected content based on a shared screen selection received from user terminal 220. According to one embodiment, when receiving multiple selected contents, processor 334 may be configured to automatically generate an evaluation candidate list including the multiple selected contents. According to other embodiments, when receiving more than one selected content from the multiple contents included in the evaluation candidate list, processor 334 may generate a final evaluation candidate list including the more than one selected content. The generated evaluation candidate list and / or the final evaluation candidate list may be provided to user terminal 220 via communication module 336.

[0102] According to one embodiment, processor 334 can output content information based on a user-selected or preset evaluation method. The content information may include user information that selected the content, content-related information, the number of selected contents, and the content evaluation method (e.g., real-time preference voting, majority voting, unanimous voting, etc.). The content information, along with a list including at least one content item, can be provided to user terminal 220 via communication module 336.

[0103] Processor 334 may be configured to receive evaluations of at least one piece of content from user terminal 220 and generate an evaluation result using the received evaluations. According to one embodiment, processor 334 may be configured to receive evaluations of multiple pieces of content included in a shared evaluation candidate list in a chat window and generate an evaluation result. For example, when input regarding preferences for multiple pieces of content is received from multiple user accounts within the chat window, processor 334 may process majority voting results, generate voting results, and further, generate statistical data as an evaluation record. The voting results may include for / against voting results, majority voting results, etc. According to other embodiments, processor 334 may be configured to receive evaluations of multiple pieces of content shared in the chat window and generate an evaluation record including the evaluation results received so far. The generated evaluation result and / or evaluation record may be provided to user terminal 220 via communication module 336.

[0104] Figure 4 This is a flowchart illustrating a content evaluation method 400 for an instant messaging application according to an embodiment of the present disclosure. The content evaluation method 400 can be performed by a content evaluation system and / or a user terminal. Figure 4 As shown, the content evaluation method 400 can begin with step S410, which involves sharing a screen associated with a first user account in a chat window of an instant messaging application that includes the first user account. The chat window may include more than one user account that is different from the first user account.

[0105] Next, in step S420, at least one piece of content included in the shared screen can be selected. According to one embodiment, input indicating a selection of at least one piece of content can be received from a first user account of the shared screen. In other embodiments, input indicating a selection of at least one piece of content can be received from at least one user account among a plurality of user accounts included in the chat window.

[0106] Then, in step S430, at least one selected piece of content can be output through the chat window. This at least one piece of content can be provided to multiple user accounts contained within the chat window via a link associated with the chat window. In one embodiment, information related to the at least one piece of content, together with the selected at least one piece of content, can be output in the form of an evaluation candidate list and / or a final evaluation candidate list.

[0107] Finally, in step S440, a rating for at least one piece of content can be received from at least one user account among multiple accounts included in the chat window. According to one embodiment, a rating indicating whether or not a piece of content is liked can be received from at least one user account. In other embodiments, a rating indicating liking or disliking at least one piece of content among multiple pieces of content can be received from at least one user account.

[0108] Figure 5 This is an example diagram illustrating the operation of sharing a screen associated with a first user account 516 in a chat window 514 of an instant messaging application according to an embodiment of the present disclosure, and selecting at least one piece of content included in the shared screen 534. The first user account and other user accounts may be included in or participate in the chat window 514. In the first operation 510, the second operation 520, and the third operation 530, the first user account may display the screen of the chat window 514 on its own user terminal's display.

[0109] A screen associated with a first user account can be shared within a chat window of an instant messaging application that contains that user account. To do this, the first user account can perform input to display screen sharing within chat window 514. For example, as shown in the first operation 510, the "Watch Together" icon 512, located at the bottom of chat window 514, can be touched to select screen sharing. While the "Watch Together" icon 512 at the bottom of chat window 514 is used for screen sharing in the first operation 510, it is not limited to this; any link or icon enabling screen sharing of chat window 514 can be configured at a location within chat window 514.

[0110] In the chat window, input for screen sharing can be received through the first user account, and the screen associated with the first user account can be displayed in at least a portion of the chat window. According to one embodiment, when the "Watch Together" icon 512 displayed in the first operation 510 is touched, an interface for sharing an application or program can be displayed. This application or program is any application or program executed on the user terminal running the first user account. For example, as shown in the second operation 520, a screen of a shopping page 522 included in a shopping application executed on the user terminal can be displayed, and a REC icon 524 can be displayed at the bottom of the screen. In the second operation 520, when the REC icon 524 is touched, the screen including the shopping page 522 can be output in at least a portion of the chat window 514. Figure 5 The second operation 520 shows the intermediate process of having the first user account confirm the screen to be shared before sharing the screen associated with the first user account 516. However, it is not limited to this. When the "Watch Together" icon 512 is touched, the application or program running in the first user account can be shared directly in the chat window 514 without the intermediate process.

[0111] At least one piece of content contained in the shared screen 534 can be output through the chat window 514. According to one embodiment, a screen including a shopping page 522 can be shared in the chat window 514, and at least one piece of content from a plurality of contents contained in the shared screen 534 can be selected. As shown in the third operation 530, the shared screen 534 can be displayed in the background screen of the chat window 514.

[0112] At least one piece of content contained in the shared screen 534 can be selected by any user account contained in the chat window 514. According to one embodiment, a first user account can select at least one piece of content contained in the shopping page 522. For this purpose, input (e.g., touch input, etc.) showing a selection of a portion corresponding to at least one piece of content contained in the shopping page 522 can be received. For example, as shown in the third operation 530, touch input can be received for portion 532_1 corresponding to product content A, portion 532_2 corresponding to product content C, and portion 532_3 corresponding to product content F contained in the shared screen 534. Figure 5 The diagram shows at least one content included in the screen 534 that allows a first user account of the chat window 514 to select sharing, but it is not limited thereto, and may be configured to include at least one content included in the screen 534 that allows other user accounts of the chat window 514 to select sharing.

[0113] The portions corresponding to the various contents contained in the shared screen, selectable by a user account, can be separated and analyzed in various ways. According to one embodiment, portions 532_1 corresponding to product A, 532_2 corresponding to product C, and 532_3 corresponding to product F in the shared screen 534 can be specified using a page structure set in the shopping page 522. This page structure may include a structure defined on the shopping page 522 by the system providing the shopping page 522, specifying the portions corresponding to the various contents. In other embodiments, portions 532_1 corresponding to product A, 532_2 corresponding to product C, and 532_3 corresponding to product F in the shared screen 534 can be specified through image recognition processing by a user terminal or a content evaluation system. For example, the processor of a user terminal executing an instant messaging application can analyze the image including the shopping page 522 as a shared screen, thereby separating and identifying the portions corresponding to the various contents contained in the shopping page 522. As another example, the processor of the content evaluation system receives images of shopping page 522 as a shared screen from the user terminal, analyzes the received images, and separates and identifies the parts corresponding to the various contents contained in shopping page 522.

[0114] Figure 6 This is an example diagram illustrating the operation of outputting at least one selected piece of content in a chat window 614 of an instant messaging application according to an embodiment of the present disclosure, and outputting an evaluation result for at least one piece of content through the chat window 614. In this embodiment, as shown in the first operation 610, multiple user accounts or users can be included or participate in the chat window 614, and send and receive text messages to each other through the chat window 614. In addition, the screen can be shared through any user account included in the chat window 614. For example, the shared screen 612 can be shared by user D in the chat window.

[0115] A first piece of content included in a shared screen can be selected in the chat window, and the selected first piece of content can be output through the chat window. In one embodiment, as shown in the first operation 610, user account D can select product C content in a shared screen 612 including a shopping page, and can output a message including the selected product C content through the chat window 614. The message 616 includes not only the selected product C content, but also information 618 related to the product C content. For example, the information 618 related to the product C content can include the product C name "Product C" and the product C price "29,900 Korean Won," which are texts identified from the shared screen 612 as associated with product C. Furthermore, information related to product C can be retrieved online using at least one of the product C image, product C name, and product C price, which are information extracted from the shared screen 612 as associated with product C content. In this embodiment, the color information "color: black, white" and the material information "material: down" of product C content can be retrieved in association with product C content and thus included in message 616. Additionally, message 616 may include an input area 622 that displays preferences for the selected product content C. When message 616 containing product content C is output in chat window 614, at least one user account among multiple user accounts included in chat window 614 can evaluate product content C by selecting the "agree" or "disagree" icon included in area 622 of message 616. As yet another example, at least one user account among multiple user accounts included in chat window 614 can enter a comment associated with area 622 of message 616.

[0116] Evaluation results for the performed content can be output from at least one user account through a chat window. According to one embodiment, when a user account included in chat window 614 evaluates the content of product C, a message 632 including the evaluation result for product C can be displayed through chat window 614. For example, message 632 may include percentage information 634 of the evaluations from multiple user accounts that responded within chat window 614. Although the evaluation result is shown as a percentage in the second operation 630, it is not limited to this; the evaluation result may include various information such as the number of evaluators for each level of preference and the names of the evaluators. Furthermore, Figure 6 The text shows the level of preference for product C, including both positive and negative opinions; however, it is not limited to this and can express the degree of preference in more detail. Comments entered in association with area 622 contained in message 616 can be analyzed, and evaluation results can be displayed based on the analysis results.

[0117] Figure 7This is an example diagram illustrating the operation of sharing a video captured by an image sensor associated with a first user account in a chat window 714 according to an embodiment of the present disclosure, and outputting at least one selected content in a screen 712 including the shared video. Figure 7 The operations illustrated in the diagram refer to the operations displayed in the chat window 714 of an instant messaging application executed by the user terminal associated with the first user account. Video can be recorded or captured using an image sensor installed on the user terminal associated with the first user account, and the screen 712 containing the recorded or captured video can be shared through the chat window 714. For example, such captured video can be shared during a video call between the first user account and one or more other user accounts included in the chat window 714. Figure 7 The diagram shows multiple user accounts within a chat window 714 communicating with each other via text while sharing a captured video. However, it is not limited to this; a captured video can be shared during a video call without a text chat window.

For example, as shown in the first operation 910, regarding the selection of item B (dumplings), the first user account can send and receive text messages with user D, who is another user account in chat window 914.

[0124] When at least one item is selected on the shared screen 912, the selected item can be output through the chat window. According to one embodiment, after the first user account selects item B (dumplings), touching the shopping cart icon 916 stores item B in the shopping information system. For example, as shown in the second operation 920, when item B (dumplings) is selected, a text message "Item added to shopping cart" can be displayed in the chat window 914. Then, touching the shopping cart icon 916 displays the currently selected item content through the chat window 914. For example, as shown in the third operation 930, the selected item B (dumplings) can be output through the chat window 914. Thus, as shown in the second operation 920 and the third operation 930, multiple user accounts included in the chat window 914 can access the currently selected item content of the first user account through the shopping cart icon 916, thereby expressing their thoughts or providing feedback on the selected item content in real time.

[0125] Figure 10 This is an example diagram illustrating the operation of selecting one or more items from a plurality of items included in an evaluation candidate list 1012 according to an embodiment of the present disclosure, generating a final evaluation candidate list 1024 including the selected items, and sharing it through a chat window. According to one embodiment, as shown in the first operation 1010, the evaluation candidate list 1012 may include a plurality of product items. The plurality of product items may be selected by at least one user account included in the chat window 1014. For example, when the shopping cart icon 1016 is touched in the chat window 1014, the evaluation candidate list 1012 can be shared through the chat window 1014.

[0126] One or more items can be selected from the candidate list to generate a final candidate list that includes the selected items. According to one embodiment, among the A, F, and C items in the candidate list 1012 output through the chat window 1014, product A and product F can be selected.
