[0017] It should be noted that the acquisition, storage, use, processing, etc. of data in the technical solutions of the present disclosure comply with relevant provisions of national laws and regulations, and do not violate public order and good customs.

[0018] Figure 1 The flowchart of the virtual role-based interaction method of an embodiment of the present disclosure is suitable for a server, as shown in Figure 1 The method comprises the following steps: S101, in response to detecting that a target account raises an item question for a recommended item in a main interactive live stream, obtaining reply information for replying to the item question, the target account being any account watching the main interactive live stream.

[0019] During the process of live streaming by a digital person, the digital person as the anchor can be determined as a virtual role as the anchor object of the live room as the main interactive live stream in the current scene. When a user raises a corresponding question on the public screen of the live room, the digital person virtual role in the current live room can reply to the corresponding question for the user.

[0020] Among them, the space for interaction through virtual roles such as live rooms can be determined as a virtual interaction space.

[0021] In the virtual interactive space, a related live stream can be played, and through the playing of the live stream, the live interaction of the virtual role as the host in the virtual interactive space to the user can be realized. In this scenario, the live stream can be determined as the main interactive live stream in the virtual interactive space.

[0022] During the playing of the main interactive live stream in the virtual interactive space, any watching account in the live room can ask questions about the recommended items in the live content. In the interactive area of the virtual interactive space, a question about the currently introduced and recommended items in the live room can be detected. The question can be determined as the item question detected during the playing of the main interactive live stream in the virtual interactive space. In this scenario, the account that asks the item question can be determined as the target account that asks the item question.

[0023] The detection of the item question can be performed through the barrage messages during the playing, or through the interactive messages in the interactive area. Here, no specific limitation is made.

[0024] In this scenario, the virtual interactive space needs to reply to the detected item question separately. The information used for replying to the item question can be obtained, which is the reply information of the item question.

[0025] The reply information can be filtered based on a preset question and answer knowledge database, or can be generated based on the model capability of a large model. Here, no specific limitation is made.

[0026] It should be noted that the number of item questions detected during the playing of the main interactive live stream can be multiple. In this scenario, multiple reply information of the multiple item questions can be generated respectively, that is, when multiple item questions are detected in the main interactive live stream, the multiple item information can be replied to separately and synchronously.

[0027] S102, based on the reply information, generating an extended interactive live stream for the target account, the extended interactive live stream being used for replying to the item question asked by the target account.

[0028] In the embodiments of the present disclosure, in order to reply to the item question based on the reply information, the corresponding extended live stream can be constructed based on the reply information, so as to obtain the corresponding extended interactive live stream.

[0029] Optionally, based on the live stream construction algorithm in the related art, the live stream required for the separate reply to the item question based on the reply information can be constructed, and the live stream is the extended interactive live stream of the reply information.

[0030] It can be understood that the playing of the extended interactive live streaming based on the reply information on the client of the corresponding target account can realize the separate live reply to the corresponding item question on the client.

[0031] S103, push the extended interactive live streaming to the client logged in by the target account, wherein the client switches back to the main interactive live streaming after playing the extended interactive live streaming.

[0032] The main interactive live streaming is normally played when the extended interactive live streaming is played, and the extended interactive live streaming is used to reply to the item question raised by the target account.

[0033] In the embodiments of the present disclosure, after obtaining the extended interactive live streaming to be played for replying to the item question, the extended interactive live streaming can be pushed to the client currently logged in by the target account sending the corresponding item question, and the extended interactive live streaming is played through the client to separately reply to the item question raised by the target account logged in on the client.

[0034] The extended interactive live streaming can be pushed to the client logged in by the target account based on the data pushing method in the related art through the preset data interaction link between the server and the client, so as to be played on the display interface of the client, and then separately reply to the user under the target account for the item question.

[0035] In the embodiments of the present disclosure, after the playing of the extended interactive live streaming on the client logged in by the target account ends, the display interface of the client can switch back to the display interface of the main interactive live streaming, so that the user under the target account can continue to watch the index content of the main interactive live streaming.

[0036] It should be noted that during the execution of the extended interactive live streaming, the main interactive live streaming of the virtual interactive space is normally played, that is, for the accounts without raising questions, the corresponding live content can be normally watched based on the main interactive live streaming played in the virtual interactive space, and the separate live reply to each item question does not affect the live content watched by other users without raising item questions in the virtual interactive space.

[0037] The interaction method based on virtual roles provided in the present disclosure generates corresponding reply information when detecting an item question, to reply to the target account that proposes the item question individually, and generates respective reply information of multiple item questions when detecting multiple item questions, and replies to the multiple item questions individually in a live broadcast, which realizes personalized answers to item questions, improves the reply accuracy of item questions, realizes synchronous live broadcast reply to multiple item questions, and compared with the related art that relies on manual reply, improves the reply efficiency and accuracy, reduces the degree of artificial dependence and reply cost, optimizes the reply experience of users, improves the interaction efficiency and quality of the virtual interaction space, improves the possibility of cooperation achievement in the scenario of achieving cooperation through the virtual interaction space, and further improves the completion rate and completion quality of the cooperation achievement index to be achieved, and improves the user stickiness.

[0038] In the above embodiments, regarding the reply to the at least one item question individually, the following can be combined Figure 2 It is further understood that Figure 2 The flowchart of the interaction method based on virtual roles of another embodiment of the present disclosure is suitable for a server, such as a server of a virtual interaction space, and as shown in the figure, the method comprises the following steps. Figure 2 The method comprises the following steps. S201, in response to detecting that a target account proposes an item question for a recommended item in a main interactive live broadcast stream, obtaining reply information for replying to the item question, the target account being any account watching the main interactive live broadcast stream.

[0039] In the embodiments of the present disclosure, during the playing process of the main interactive live broadcast stream, the watching account can perform other interactions, in this scenario, the detected interaction information needs to be screened to determine the item question that needs to be replied to in a live broadcast individually.

[0040] Optionally, in response to detecting the interaction information during the playing process of the main interactive live broadcast stream, obtaining a semantic analysis result of the interaction information.

[0041] In the embodiments of the present disclosure, the information sent by the watching account during the playing process of the main interactive live broadcast stream can be determined as the interaction information, in this scenario, the semantic analysis algorithm in the related art can be used to perform semantic analysis on multiple pieces of interaction information sent by the watching account respectively, to obtain the semantic analysis result of the interaction information.

[0042] Optionally, in response to the semantic analysis result indicating that the interaction information is item inquiry information, determining that the interaction information is an item question that needs to be replied to in a live broadcast.

[0043] In this embodiment of the disclosure, for any interactive information, when the semantic parsing result of the interactive information indicates that the interactive information is a query for relevant information of the corresponding item currently being introduced in the live broadcast room, the information can be identified as item query information, and then the item query information can be identified as the currently detected item question that needs to be answered separately in the live broadcast.

[0044] Optionally, in response to detecting an item query, the item query is analyzed to determine the query object corresponding to the item query.

[0045] In this embodiment of the disclosure, when an item question is detected, the item question can be analyzed based on information analysis methods in related technologies, and the keyword information of the item question can be determined based on the processing results of the analysis algorithm.

[0046] Specifically, when the question about an item is presented in text form, the text of the question can be analyzed using natural language processing methods in related technologies. When the question about an item is presented in speech form, the audio of the question can be analyzed using audio analysis algorithms in related technologies. No specific limitations are made here.

[0047] During the playback of the main interactive live stream in the virtual interactive space, information can be introduced for each of the multiple resource items set up in the virtual interactive space. In this scenario, when an item question inquires about the detailed information of a certain dimension of any of the multiple resource items, that resource item can be identified as the object of inquiry for that item question.

[0048] Optionally, the descriptive information of the inquiry object is obtained, and the candidate response information of each inquiry object is obtained based on the descriptive information.

[0049] In this embodiment of the disclosure, when asking about an item, the corresponding inquiry object is provided with corresponding descriptive information. The descriptive information may include the appearance description information of the inquiry object, the description information of the usage method, and the description information of the activities preset for the inquiry object, etc., which are not specifically limited here.

[0050] In this scenario, the description information of the object of inquiry can be filtered and queried to extract at least some information that can answer the question about the item. Then, based on the at least some information, the corresponding answer information can be constructed. The answer information obtained by the construction, which includes the at least some information filtered from the description information, can be determined as the candidate answer information for the question about the corresponding item.

[0051] Optionally, the response preferences of the target account that asked the question about the item are obtained, and the candidate response information of the question about the item is adjusted based on the response preferences to obtain response information that matches the response preferences. The response preferences include at least the response method preference and response language style preference of the target account.

[0052] In this embodiment of the disclosure, for questions about items, the target account that raises the question has a corresponding user profile. The user profile of the target account can be processed by the user profile parsing algorithm in the relevant technology, and then the target account's preferred answering methods and answering language style and other related information can be obtained based on the result of the algorithm processing.

[0053] In this scenario, the parsed information, such as the preferred response methods and language styles of the target account asking the item question, can be used to determine the target account's response preferences.

[0054] In this scenario, based on style adjustment algorithms in related technologies and the response preferences of the target account, the candidate response information for the question about the item can be adjusted according to preferences, and the adjusted response information can be determined as the response information for the question about the item.

[0055] S202, Based on the response information, generate an extended interactive live stream for the target account.

[0056] The extended interactive live stream is used to answer questions about items raised by the target account.

[0057] Optionally, based on the item-based question, candidate response video scripts associated with the anchor object in the main interactive live stream can be determined.

[0058] In this embodiment of the disclosure, the virtual interactive space has multiple question information items for possible questions, and the question information items that match the item question can be filtered from these multiple question information items.

[0059] In this scenario, after determining the question information item for the item question, the corresponding answer strategy can be obtained. Then, from the answer video templates corresponding to the answer strategy, the answer video templates associated with the anchor of the live stream in the main interactive live stream watched by the target account can be selected. The script corresponding to the answer video template can be determined as the candidate answer video script for the item question.

[0060] Specifically, the anchor object in the main interactive live stream can be identified as the virtual object used when giving individual replies.

[0061] Optionally, based on the response information, the candidate response video script is adjusted to obtain the target response video script.

[0062] In this embodiment of the disclosure, the script adjustment method in the related art can be used to adjust the candidate answer video script corresponding to the question of the item based on the answer information corresponding to the question of the item, and then determine the adjusted video script carrying the answer information as the target answer video script for the question of the item.

[0063] It should be noted that the target response video script includes information such as the response methods that the virtual character needs to use when responding, but no specific restrictions are made here.

[0064] Optionally, based on the target response video script, an extended interactive live stream is constructed to provide video responses to questions about the item.

[0065] In this embodiment of the disclosure, a corresponding live stream can be constructed based on a live stream construction algorithm in the related technology, which serves as an extended interactive live stream to be executed when a virtual character makes a separate response to a question about a corresponding item based on the response information.

[0066] S203 pushes the extended interactive live stream to the client logged in by the target account.

[0067] The client switches back to the main interactive live stream after playing the extended interactive live stream.

[0068] In this embodiment of the disclosure, the push of the extended interactive live stream to the client logged into by the target account can be understood in conjunction with the relevant content in the above embodiments, and will not be repeated here.

[0069] After pushing the extended interactive live stream to the target account's client, the following can be used to understand: Optionally, in response to receiving a request from the client to close the extended interactive area of ​​the extended interactive live stream, a corresponding stop playback command is sent to the client.

[0070] In this embodiment of the disclosure, when the extended interactive live stream needs to be stopped on the client playing it, the client can send a corresponding close request to the server, and the server generates a corresponding stop playback instruction based on the received close request and sends it to the client.

[0071] In this scenario, the client can shut down the playback of the extended interactive live stream based on the received stop playback command.

[0072] Optionally, in response to receiving feedback that the extended interactive live stream has stopped playing, a command to resume playback of the main interactive live stream is sent to the client.

[0073] In this embodiment of the disclosure, after the client closes the extended interactive live stream being played on it, it can return the corresponding stop playback feedback to the server. After receiving the stop playback feedback, the server can determine that the currently playing individual live stream response on the client has ended. In this scenario, the client needs to resume playing the live content of the main interactive live stream.

[0074] Then, the server can send a command to resume playback of the main interactive live stream to the client. Once the client receives the command, it can resume displaying the live content of the main interactive live stream on its screen.

[0075] Optionally, in response to the extended interactive live stream stopping, the system obtains the response feedback information for the corresponding item questions and optimizes the responses to the item questions based on the response feedback information.

[0076] In this embodiment of the disclosure, after the extended interactive live stream stops playing, a satisfaction survey option can be popped up on the client of the target account that asked the question about the item, so as to obtain feedback information on user satisfaction.

[0077] In this scenario, the satisfaction level of users under the target account with the corresponding live broadcast response can be identified based on the response feedback information. Based on this satisfaction level, the relevant process of individual live broadcast responses to item questions based on virtual characters can be optimized, so that the optimized process can be used to achieve individual live broadcast responses to item questions based on virtual characters in the future.

[0078] The virtual role-based interaction method proposed in this disclosure adjusts candidate response information based on the target account's response preferences to obtain corresponding response information, improving the fit between response information and user preferences. It provides live responses to item-related questions, achieving personalized answers and improving response accuracy. When multiple item questions are detected, it generates separate response information for each question and provides individual live responses to each, achieving simultaneous live responses to multiple item questions. Compared to related technologies that rely on manual responses, this method improves response efficiency and accuracy, reduces reliance on manual responses and response costs, optimizes the user's response experience, and enhances the interaction efficiency and quality of the virtual interactive space. In scenarios where cooperation is achieved through the virtual interactive space, it increases the likelihood of successful cooperation, thereby improving the completion rate and quality of desired cooperation achievement indicators and increasing user stickiness.

[0079] This disclosure also proposes an interaction method based on virtual characters, which can be combined with... Figure 3 understand, Figure 3This is a flowchart illustrating another embodiment of the virtual character-based interaction method disclosed herein, applicable to a client, such as... Figure 3 As shown, the method includes: S301, Play the main interactive live stream pulled from the server, in which at least one item is recommended.

[0080] In this embodiment of the disclosure, the client watches the live content of the main interactive live stream on its display screen. The client can send a corresponding live stream viewing request to the server. After receiving the live stream viewing request, the server sends the main interactive live stream to the client for playback.

[0081] The main interactive live stream content may include recommendations and introductions of at least one item, enabling cooperation between the accounts watching the live stream content and the accounts distributing the corresponding item resources in the main interactive live stream.

[0082] S302, in response to a question about any item recommended in the main interactive live stream, sends an item question to the server.

[0083] In this embodiment of the disclosure, the account currently logged in to the client can watch the live content of the main interactive live stream. During the viewing of the live content, the user of the account currently logged in to the client can ask questions about any item recommended in the live stream. Specifically, based on the live interactive questioning method in related technologies, the user can input the corresponding question in the interactive area of ​​the live stream room of the main interactive live stream to complete the questioning operation for any item.

[0084] In this scenario, the server can detect information in the interactive area of ​​the live stream and select the corresponding items to ask questions based on the detection results.

[0085] S303 receives the extended interactive live stream sent by the server. The extended interactive live stream is used to answer questions about items.

[0086] In this embodiment of the disclosure, the reception of extended interactive live streams can be achieved based on the interaction link between the server and the client. Specifically, for the target account that raises a question about an item, the client logged into by the target account can only receive the extended interactive live stream corresponding to the question raised by the target account.

[0087] In this scenario, the extended interactive live stream contains the answer information for item-related questions raised by the target account currently logged in. Based on the received extended interactive live stream, the client can provide individual answers to item-related questions raised by users under the target account.

[0088] S304, Play extended interactive live stream, switch back to main interactive live stream after the extended interactive live stream has finished playing.

[0089] In this embodiment of the disclosure, for questions about items, the virtual interactive space can be set up with a corresponding live response area, which can be determined as an extended interactive area used when answering questions about items.

[0090] In this scenario, the client can play the received extended interactive live stream, allowing the virtual character to broadcast responses to item-related questions raised by the target account in the extended interactive area set up on the client, thus achieving a separate live response to the item-related question.

[0091] It should be noted that, as can be seen from the relevant content in the above embodiments, during the execution of the extended interactive live stream, the main interactive live stream of the virtual interactive space will play normally. In this scenario, when the extended interactive live stream played on the client is closed, the client can be switched from playing the content of the extended interactive live stream back to the live content corresponding to the main interactive live stream.

[0092] In other words, after the extended interactive live stream on the client is closed, the client's screen will return to display the live content of the main interactive live stream after the corresponding closing time of the extended interactive live stream. The logged-in account of the client can continue to watch the live content of the main interactive live stream.

[0093] The virtual character-based interaction method proposed in this disclosure provides individual live-streamed responses to item-related questions raised by target accounts on the client logged in by those accounts. This achieves personalized answers to item questions, optimizes the user's response experience, and improves the efficiency and quality of interaction in the virtual interactive space. When extending the interactive live stream for individual live-streamed responses, the main interactive live stream content is played normally, reducing the impact of item question responses on the main interactive live stream content. While optimizing the user's response experience, it also optimizes the live-stream viewing experience for users under other accounts. In scenarios where cooperation is achieved through the virtual interactive space, it increases the likelihood of cooperation, thereby improving the completion rate and quality of the required cooperation achievement indicators and enhancing user stickiness.

[0094] In the above embodiments, the virtual character-based interaction method applicable to the client can be combined with... Figure 4 To understand further, Figure 4 This is a flowchart illustrating another embodiment of the interaction method based on virtual characters disclosed herein, such as... Figure 4 As shown, the method includes: S401 plays an extended interactive live stream within a preset extended interactive area to answer questions about items raised by the target account through a preset virtual character.

[0095] The content of the response broadcast is based on the response information corresponding to the extended interactive live stream.

[0096] In this embodiment of the disclosure, based on the playback of the extended interactive live stream corresponding to the answer information of the question about the item, the corresponding extended interactive area can pop up on the current display page of the virtual interactive space, and virtual characters such as digital humans are set in the extended interactive area.

[0097] In this scenario, based on the playback of this extended interactive live stream, the virtual character can broadcast through voice announcements combined with digital human body movements and other operations. The broadcast content can be determined based on the response information corresponding to the extended interactive live stream.

[0098] It should be noted that the extended interactive area can be either the interactive display area corresponding to the main interactive live stream or a small window area set within the interactive display area of ​​the main interactive live stream.

[0099] Optionally, the extended interactive area corresponding to the extended interactive live stream can be a small window area set in the display area of ​​the main interactive live stream on the client used by the target account that asked the question about the corresponding item. In this scenario, the live stream response in the extended interactive area can be displayed simultaneously with the display area of ​​the main interactive live stream.

[0100] Optionally, when displaying the virtual character's responses within the extended interactive area, the live content corresponding to the main interactive live stream is weakened. This weakening includes blurring the image and removing the sound from the display area corresponding to the main interactive live stream. In other words, when a virtual character in the extended interactive area answers a question about an item, the live video and audio in the main interactive live stream's display area can be weakened. This weakening process can include blurring the video and eliminating the audio in the main interactive live stream's display area to reduce the impact of the live content in the main interactive live stream's display area on the live responses displayed in the extended interactive area.

[0101] Optionally, the size of the extended interactive area can also be the same as the display area of ​​the main interactive live stream. In this scenario, the extended interactive area can cover the display area of ​​the main interactive live stream, so that the display area of ​​the virtual interactive space only displays the live responses in the extended interactive area.

[0102] In this scenario, when displaying the virtual character's response broadcast within the extended interactive area, the live content corresponding to the main interactive live stream is weakened. This weakening includes screen overlay and sound cancellation processing on the display area corresponding to the main interactive live stream.

[0103] In other words, when a virtual character in the extended interactive area gives a live response, the display area of ​​the main interactive live stream on the client of the target account that asked the question about the corresponding item can be directly turned off. This allows the extended interactive area to cover the display area of ​​the virtual interactive space and eliminate the sound in the display area of ​​the main interactive live stream, thus enabling users to receive a more accurate individual live response from the virtual character to their question about the item.

[0104] It should be noted that the weakening of the live content corresponding to the main interactive live stream mentioned above includes either blurring the image and removing the sound in the display area corresponding to the main interactive live stream, or covering the image and removing the sound in the display area corresponding to the main interactive live stream. These can be set based on user needs or other application scenarios, and are not specifically limited here.

[0105] S402, in response to detecting a request to close the extended interactive area of ​​the extended interactive live stream, a request to close the extended interactive live stream is sent to the server.

[0106] In this embodiment of the disclosure, the extended interactive live stream is set with corresponding playback end conditions. The extended interactive area of ​​the extended interactive live stream can be used to detect relevant playback end information. When the corresponding information is detected, it can be determined that the user under the target account needs to stop watching the live content of the extended interactive live stream.

[0107] In this scenario, the client can generate a close request for the extended interactive live stream and send the close request to the server.

[0108] Optionally, in response to the detection of a reply end keyword, the operation of the end option of the extended interactive live stream within the extended interactive area of ​​the extended interactive live stream, and the failure to detect at least one of the following triggers within a set time after the virtual character in the extended interactive area has finished broadcasting the content of the live reply, the system determines that the extended interactive area of ​​the extended interactive live stream has been closed, and generates a close request based on the close information.

[0109] In other words, when a user sends the corresponding end-of-response keyword in the extended interaction area, it can be determined that the user needs to stop the current live broadcast response. In this scenario, it can be determined that a close message has been detected in the extended interaction area.

[0110] Furthermore, when a user interacts with the preset end option in the extended interaction area, it can be determined that the user needs to stop the current live broadcast response. In this scenario, it can be determined that a close message has been detected in the extended interaction area.

[0111] Furthermore, if no user interaction information is detected within the set time after the virtual character in the extended interaction area has completed the broadcast of the target response information, it can be determined that the current user may not need to continue watching the virtual character's response broadcast. In this scenario, it can be determined that a close message has been detected in the extended interaction area.

[0112] In this embodiment of the disclosure, when at least one of the above three situations is detected, it can be determined that the user under the target account does not need to continue watching the live content of the currently playing extended interactive live stream. In this scenario, a corresponding close request can be generated based on the detected close information and sent to the server.

[0113] It should be noted that the conditions required to close the extended interactive area can include the three conditions mentioned above, as well as other settings, which are not specifically limited here.

[0114] S403, in response to receiving a stop playback command from the server, stops the playback of the extended interactive live stream and sends a corresponding stop playback feedback to the server.

[0115] In this embodiment of the disclosure, after the client sends a close request to the server, it can receive a stop playback instruction returned by the server. After receiving the stop playback instruction, the client can close the playback of the currently playing extended interactive live stream.

[0116] In this scenario, the client can also generate a corresponding stop playback feedback and return it to the server to inform the server that the extended interactive live stream currently playing on the client has been closed.

[0117] It should be noted that after the extended interactive live stream is closed, the client needs to restore the display of the live stream content. This can be understood in conjunction with the following: Optionally, the pause time of the extended interactive live stream can be obtained, and the live content of the main interactive live stream can be resumed after the pause time.

[0118] Optionally, the transition effect between the extended interactive area of ​​the extended interactive live stream and the display area of ​​the main interactive live stream is obtained. Based on the transition effect, the extended interactive area is closed and the main interactive live stream plays the live content after the pause time.

[0119] In this embodiment of the disclosure, the viewers in the display area of ​​the main interactive live stream include not only users under the target account who asked questions about the item, but also users under other viewing accounts who did not ask questions about the item. In this scenario, when each extended interactive live stream is played separately, the main interactive live stream will also play the originally set live content normally.

[0120] In this scenario, when the extended interactive live stream on the client ends and returns to play the main interactive live stream, the main interactive live stream can contain content after the extended interactive live stream has stopped playing.

[0121] Specifically, the closing time of the extended interactive area of ​​the extended interactive live stream on the client can be determined as the stop playback time of the extended interactive live stream.

[0122] In this scenario, the live content of the main interactive live stream's display area during the pause time can be obtained. On the client of the target account asking the question about the corresponding item, a transition effect is used to transition the display content of the last frame of the extended interactive area with the display content of the next frame of the main interactive live stream's display area at the pause time. This allows for a visual transition between the extended interactive area of ​​the extended interactive live stream and the display area of ​​the main interactive live stream on the client, so that the main interactive live stream's live content can be resumed after the extended interactive live stream ends.

[0123] The transition effect can be a fade-in / fade-out effect or other effects; no specific restrictions are made here.

[0124] The interactive method based on virtual characters proposed in this disclosure provides separate live-streamed answers to item-related questions raised by the target account on the client logged in by that account. This achieves personalized answers to item questions, optimizes the user's answering experience, and closes the live-streamed answers played separately on the client upon detecting the closure of the extended interactive live stream, improving the efficiency and quality of interaction in the virtual interactive space. The live-stream content corresponding to the main interactive live stream is restored based on transition effects, improving the aesthetics of the transition between the extended and main interactive live streams. While providing separate live-streamed answers in the extended interactive live stream, the live-stream content of the main interactive live stream plays normally, reducing the impact of item question answers on the main interactive live stream content. In addition to optimizing the user's answering experience, this method also optimizes the live-streaming viewing experience for users under other accounts, increasing user engagement.
