[0021] As an optional but non-restrictive implementation, in response to a user's active request, a prompt message can be sent to the user, such as a pop-up window, where the prompt message can be presented in text format. Furthermore, the pop-up window can also include a selection control allowing the user to choose "agree" or "disagree" to provide personal information to the electronic device.

[0022] It is understood that the above notification and user authorization process are merely illustrative and do not constitute a limitation on the implementation of this disclosure. Other methods that comply with relevant laws and regulations may also be applied to the implementation of this disclosure.

[0023] Figure 1 A schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented is shown. In this example environment 100, an application 115 is installed on a terminal device 110. A user 140 can interact with the application 115 via the terminal device 110 and / or an attached device of the terminal device 110.

[0024] In some embodiments, application 115 can provide user 140 with various services related to media content (also referred to as media items, media content items, content items, etc.), including browsing, commenting, forwarding, creating (e.g., shooting and / or editing), and publishing media content. In some embodiments, application 115 can be a content generation application (e.g., an application primarily for media content generation), a content editing application (e.g., an application primarily for media content editing), etc. In some embodiments, application 115 can also be any other suitable application capable of generating media content. Media content can include one or more types of content, such as video, images, GIFs, image sets, audio, text, etc.

[0025] exist Figure 1 In environment 100, if application 115 is active, terminal device 110 can display the interface 150 of application 115. Interface 150 can include various interfaces provided by application 115, such as content presentation interfaces, content creation interfaces, content publishing interfaces, message interfaces, personal homepages, etc. Application 115 can provide content generation functions to generate various types of media content within application 115, and the generated media content can be displayed on a specified interface.

[0026] In some embodiments, terminal device 110 communicates with server 120 to provide services to application 115. Terminal device 110 can be any type of mobile terminal, fixed terminal, or portable terminal, including mobile phones, desktop computers, laptop computers, notebook computers, netbook computers, tablet computers, media computers, multimedia tablets, personal communication system (PCS) devices, personal navigation devices, personal digital assistants (PDAs), audio / video players, digital cameras / camcorders, positioning devices, television receivers, radio receivers, e-book devices, gaming devices, or any combination thereof, including accessories and peripherals of these devices or any combination thereof. In some embodiments, terminal device 110 can also support any type of user-facing interface (such as "wearable" circuitry).

[0027] Server 120 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks, and big data and artificial intelligence platforms. Server 120 may include, for example, computing systems / servers such as mainframes, edge computing nodes, computing devices in cloud environments, etc.

[0028] In some embodiments, the video processing system 110 may generate media content using a machine learning model 130. The machine learning model 130 may be deployed locally on the video processing system 110 or on other devices / systems (e.g., server 120). The video processing system 110 may, for example, directly utilize the locally deployed machine learning model 130 or invoke a machine learning model 130 deployed on another device / system via a communication connection to generate media content.

[0029] Machine learning model 130 can be based on any suitable model architecture, including but not limited to Transformer models, convolutional neural networks (CNNs), recurrent neural networks (RNNs), deep neural networks (DNNs), and so on. In some embodiments, machine learning model 130 can be based on a language model (LM). A language model learns from a large corpus and has question-answering capabilities. Machine learning model 130 can also be based on other suitable models. Although only a single machine learning model 130 is shown in the figure, multiple machine learning models can exist. If machine learning model 130 includes multiple models, these multiple models can include models configured to perform the same or similar tasks, or models configured to perform different tasks.

[0030] It should be understood that the structure and function of the various elements in environment 100 are described for illustrative purposes only and do not imply any limitation on the scope of this disclosure.

[0031] While some automated content creation tools are currently available, such as video and image generators, users still need to define the content theme and script themselves. For example, if a user wants to create a video, they typically edit the script themselves and use video editing tools to edit the video footage to create a target video with accompanying narration. If users are unsure what kind of media content they want to generate, they cannot provide a precise theme and content elements, which affects the efficiency and diversity of the generated media content. Furthermore, since users' knowledge and existing information are usually limited, the media content generated based on their own knowledge and existing information may have limitations. The goal is to provide users with creative ideas, help them choose topics, and generate media content efficiently and conveniently.

[0032] In view of the above, an improved content generation scheme is proposed according to embodiments of the present disclosure. According to the scheme of the embodiments of the present disclosure, in response to a content expansion request including indication information, expanded content is presented in a first area of ​​a first interface. The expanded content is generated at least based on the indication information and includes at least one set of content elements having a hierarchical relationship. In response to the selection of at least one content element from the at least one set of content elements, the selected at least one content element is presented in a second area of ​​the first interface. In response to a content generation request acting on the second area, media content is generated based at least on at least one content element in the second area.

[0033] In this way, starting with simple prompts, users can expand upon a large number of content elements for media content generation. These content elements have a hierarchical relationship, with each level building upon the content of its predecessor, thus allowing for continuous expansion outwards from the prompts. This helps users broaden their creative ideas and obtain the elements they desire for content creation. Consequently, automated media content generation can be achieved, improving the efficiency and diversity of media content creation.

[0034] The following description continues with reference to the accompanying drawings, illustrating some exemplary embodiments of this disclosure. The interactive methods involved in this disclosure can be implemented on terminal device 110. It should be noted that the operations performed by terminal device 110 may specifically be performed by a related application (e.g., application 115) installed on terminal device 110. Some operations described with reference to terminal device 110 may require the assistance of server 120 to complete.

[0035] In this disclosure, "trigger" refers to one or more interactive actions performed by a user on a terminal device. Furthermore, these interactive actions may be triggered within the same user interface / pop-up window or within different user interfaces / pop-up windows. This disclosure is not limited in this respect.

[0036] It should be understood that the interface shown in the accompanying drawings is merely an example, and various interface designs are possible in practice. The various graphic elements in the interface can have different arrangements and different visual representations, one or more elements can be omitted or replaced, and one or more other elements may also be present. The embodiments of this disclosure are not limited in this respect.

[0037] Figures 2A to 2K Example interfaces 200A to 200K for content generation according to some embodiments of the present disclosure are shown. The interfaces shown in example interfaces 200A to 200K can be presented on terminal device 110. For ease of discussion, reference will be made to... Figure 1The environment 100 is used to describe example interfaces 200A to 200K. Terminal device 120 can be used for interaction by receiving operations from associated users (e.g., user 140) to present corresponding interaction results.

[0038] Terminal device 110 can receive a content expansion request including instruction information in any suitable manner. In some embodiments, terminal device 110 can determine that a content expansion request including instruction information has been received in response to receiving voice containing specific content, and determine the instruction information based on the voice. For example, terminal device 110 can determine that a content expansion request has been received in response to receiving the voice message "Please generate content based on the keyword 'XX'", and can determine that the instruction information includes the keyword "XX" based on the voice message.

[0039] In some embodiments, terminal device 110 may present an interface for receiving instruction information. Terminal device 110 may, in response to confirmation of the instruction information received on the interface, determine that a content expansion request including the instruction information has been detected. (See reference...) Figure 2A Example interface 200A illustrates an example of an interface for receiving instruction information. Example interface 200A includes an input field 210, through which terminal device 110 can receive at least a portion of the instruction information. For example, if terminal device 110 receives the text “XXXX” via input field 210, then terminal device 110 can determine that the text “XXXX” is part of the instruction information. Example interface 200A also includes a control 212, through which terminal device 110 can determine, in response to receiving a trigger on control 212, that a content expansion request including the instruction information (which at least includes the text “XXXX” received via input field 210) has been detected.

[0040] In some embodiments, the terminal device 110 may also receive requests to an application (which is, for example, a...). Figure 1 The application (115) used to generate content binds to a user account (e.g., user account of user 140) and identifies information associated with that user account as part of the instruction information. This information associated with the user account may include, but is not limited to, any appropriate information such as the account's historical content generation history, historical content browsing history, historical followed materials, and preferred areas. It is understood that all this information is authorized by the user, and all information obtained by the application is user-authorized information.

[0041] Continue to refer to Figure 2AExample interface 200A may also include control 215. Terminal device 110 can, in response to receiving a trigger on control 215, determine that a binding of a user account has been received, and then obtain information associated with the bound user account, identifying the obtained information as part of the instruction information. It is understood that, in this case, terminal device 110 can, in response to receiving a trigger on control 212, determine that a content expansion request including instruction information (which may include the text "XXXX" received via input box 210 and information associated with the bound user account) has been detected.

[0042] Terminal device 110 may present a first interface in response to a content expansion request including indication information. The first interface may include a first area for presenting expanded content, which is generated at least based on the indication information and includes at least one set of content elements having a hierarchical relationship. The first interface may also include a second area for presenting a selected content element. Terminal device 110 may present at least one selected content element in the second area in response to the selection of at least one content element from the at least one set of content elements in the first area.

[0043] In some embodiments, if a set of content elements (e.g., set A) is generated based on content elements from another set of content elements (e.g., set B), set A can be referred to as a set of content elements at the next level below set B. For example, the level of a set of content elements generated based on instruction information can be referred to as level 0. Similarly, the level of at least one set of content elements generated based on content elements from a set of content elements at level 0 can be referred to as level 1, and the level of at least one set of content elements generated based on content elements from a set of content elements at level 1 can be referred to as level 2, and so on. It is understood that a set of content elements at any level other than level 0 is generated based on content elements from a set of content elements at the previous level, and each content element at that level can also be used to generate content elements at the next level. In the embodiments of this disclosure, starting from simple prompt information, new content elements can be continuously expanded downwards level by level according to user needs. The content elements at the next level can be based on the content at the previous level, thus continuously extending outwards from the prompt information to provide users with a large number of content elements suitable for media content generation.

[0044] Terminal device 110 can present at least one set of content elements in any suitable form. As an example only, terminal device 110 can present at least one set of content elements in the form of cards. That is, terminal device 110 can present at least one set of content elements by presenting at least one set of cards, each card being used to present a set of content elements. In some embodiments, to facilitate real-time access to instruction information for the user, terminal device 110 can respond to a content expansion request by presenting a card for presenting instruction information in a first area.

[0045] In some embodiments, if a given card from a plurality of cards is used to present a set of content elements, and the set of content elements in the given card is generated based on specified information, the terminal device 110 may present a connecting line for linking the specified information to the given card. The specified information may include instruction information or content elements from a previous level. For example, if a set of content elements is generated based on instruction information, the terminal device 110 may present a connecting line between the card used to present the set of content elements and the card used to present the instruction information. If a set of content elements is generated based on content elements from a previous level, the terminal device 110 may present a connecting line between the card used to present the set of content elements and the card used to present content elements from the previous level.

[0046] refer to Figure 2A and Figure 2B Terminal device 110 may present example interface 200B in response to receiving a trigger on control 212 in example interface 200A. Example interface 200B includes area 220, which illustrates an example of a first area. Terminal device 110 may present card 240 in area 220 in response to a content expansion request. Card 240 is used to present instruction information. In some embodiments, limited by interface size, card 240 may also present only at least a portion of the instruction information. For example, card 240 may be configured to present at least a portion of the instruction information received by terminal device 110 via input box 210 in example interface 200A.

[0047] In some embodiments, terminal device 110 may, in response to a content expansion request, present a set of content elements generated based on indication information in a first area. This set of content elements may, for example, indicate multiple content topics. Terminal device 110 may, for example, present a set of content elements generated based on indication information by default in the first area. It is understood that if at least one set of content elements includes only one set of content elements generated based on indication information, then the at least one set of content elements includes only the set of content elements generated based on indication information. (See reference...) Figure 2BTerminal device 110 can display cards 240 and 250 in area 220, with card 250 used to display a set of content elements generated based on instruction information. Terminal device 110 can also display a connecting line between card 240 and card 250, indicating that the set of content elements displayed by card 250 is generated based on information in card 240.

[0048] In some embodiments, the terminal device 110 may display update controls associated with each group of content elements in a first area of ​​at least one set of content elements. The terminal device 110 may update the group of content elements in response to a triggering of the update control associated with a particular group of content elements in the at least one set of elements. Regarding the specific manner of updating the group of content elements, in some embodiments, the terminal device 110 may update the group of content elements by replacing it with a newly generated group of content elements. For example, the group of content elements may include content elements 1 to 5, and the updated group of content elements may include content elements 6 to 10. That is, in this case, the multiple content elements included in the updated group of content elements may be different from the multiple content elements included in the group of content elements before the update.

[0049] In some embodiments, the terminal device 110 can update the group of content elements by adding at least one content element. For example, the group of content elements may include content elements 1 to 5, and the updated group of content elements may include content elements 1 to 10. That is, in this case, the number of content elements included in the updated group of content elements is greater than the number of content elements included in the original group of content elements, and the content elements included in the updated group of content elements include the content elements included in the original group of content elements.

[0050] refer to Figure 2B and Figure 2C In area 220 of example interface 200B, terminal device 110 can display update control 252 on card 250, which is associated with a set of content elements displayed on card 250. Terminal device 110 can update the set of content elements displayed on card 252 in response to a trigger on update control 252, and can display example interface 200C. Card 250 in area 220 of example interface 200C includes the updated set of content elements.

[0051] In some embodiments, during the updating of a set of content elements, the terminal device 110 can switch the operation state of the update control associated with that set of content elements to a non-triggerable state. The terminal device 110 can, in response to the completion of the updating of that set of content elements, switch the operation state of the update control associated with that set of content elements back to a triggerable state. The terminal device 110 can present the update control in the triggerable state and the update control in the non-triggerable state in any appropriate visual style.

[0052] The visual style of an update control in a triggerable state differs from that of an update control in a non-triggerable state. For example, terminal device 110 can gray out the update control to indicate that it is currently non-triggerable. It should be noted that all visual styles mentioned herein can include any appropriate visual style such as highlight, bold, italic, or underline. The visual styles for different content in different states can be configured according to the specific application; this disclosure does not limit the specific visual styles.

[0053] In some embodiments, if the terminal device 110 updates a group of content elements by adding at least one content element to the group, each group of content elements may include a maximum of a threshold number of content elements. The terminal device 110 may, in response to the number of content elements in an updated group reaching the threshold number, cancel the presentation of the update control associated with that group of content elements, or switch the operation state of the update control associated with that group of content elements to an untriggerable state. For example, if the threshold number is 15, and an unupdated group of content elements includes 5 content elements, and each update adds 5 new content elements to that group, the terminal device 110 can receive a maximum of two update operations on that group of content elements. The terminal device 110 may, in response to the number of content elements in that group reaching 15, cancel the presentation of the update control associated with that group of content elements, or switch the operation state of the update control associated with that group of content elements to an untriggerable state.

[0054] In some embodiments, if at least one set of content elements in the first area includes multiple sets of content elements, the multiple sets of content elements may include a set of content elements generated based on the instruction information and at least another set of content elements generated based on the content elements of the previous level. In some embodiments, the terminal device 110 may by default present the instruction information, a set of content elements generated based on the instruction information, and each set of content elements generated based on the content elements of the previous level in the first area of ​​the first interface. In this case, no additional triggering operation is required from the user; the terminal device 110 can directly present all content elements associated with the instruction information, and the terminal device 110 can provide the user with a large amount of content, allowing the user to directly search for content elements of interest, thereby improving the presentation efficiency of content elements.

[0055] In some embodiments, the terminal device 110 may also, by default, present only the indication information and a set of content elements of level 0 generated based on the indication information in the first area. In response to receiving a trigger to generate content elements in the set of content elements of level 0, the terminal device 110 may present at least one set of content elements of level 1 in the first area, where each set of content elements in the at least one set of content elements of level 1 may be generated at least based on the corresponding content elements in the set of content elements of level 0. In some embodiments, each set of content elements in the at least one set of content elements of level 1 may also be generated based on the indication information.

[0056] Similarly, terminal device 110 may also, in response to receiving a trigger to generate content elements in a set of content elements of the first level, present at least one set of content elements of the second level in a first area, wherein each set of content elements in the at least one set of content elements of the second level can be generated based on at least one of the corresponding content elements in the set of content elements of the first level and indication information. Terminal device 110 may also, in response to receiving a trigger to generate content elements in a set of content elements of the second level, present at least one set of content elements of the third level in a first area, wherein each set of content elements in the at least one set of content elements of the third level can be generated based on at least one of the corresponding content elements in the set of content elements of the second level and indication information, and so on.

[0057] In other words, in this scenario, terminal device 110 will by default only present the instruction information and the first set of content elements at level 0. Terminal device 110 will then present at least one set of content elements from subsequent levels based on user triggers. This avoids presenting too many content elements at once, helps reduce computational load, and facilitates users in browsing and finding at least one set of content elements.

[0058] In some embodiments, terminal device 110 may present generation controls associated with various content elements in a first area. Terminal device 110 may determine that a generation trigger for a content element has been detected in response to a triggering of a generation control associated with a content element at a given level. Terminal device 110 may then, in response to the generation triggering of that content element, present a set of content elements at the next level below the given level in the first area, this set of content elements being generated based on the content element corresponding to the triggered generation control.

[0059] As an example, see reference Figure 2B and Figure 2DTerminal device 110 can present generation controls associated with each content element in card 250. Terminal device 110 can, in response to receiving a trigger for the generation control associated with the level 0 content element "Topic A" in example interface 200B, determine that a generation trigger for content element "Topic A" has been received and present example interface 200D. Terminal device 110 can present card 260 in area 220 of example interface 200D, where a set of content elements (i.e., content elements A to E) included in card 260 are generated based on content element "Topic A".

[0060] In some embodiments, if a set of content elements at the next level generated based on a certain content element is presented in the first area (i.e., the terminal device 110 has received a generation trigger for that content element), the terminal device 110 may, in response to receiving another trigger for the generation control associated with that content element, cancel the presentation of the set of content elements at the next level generated based on that content element in the first area. As an example, the terminal device 110 may, in response to receiving a trigger for the generation control associated with the content element "Topic A" at level 0 in example interface 200D, determine that a cancellation of the generation trigger for the content element "Topic A" has been received, and present example interface 200B.

[0061] In some embodiments, for a certain content element, the terminal device 110 can present the corresponding generation control of the content element in a first area with different visual styles based on whether the content element has been generated (i.e., whether a set of next-level content elements has been generated based on this content element). As an example, the terminal device 110 can normally present the generation control associated with the content element "Topic A" in the example interface 200B, and fill the example interface 200D with black to present the generation control associated with the content element "Topic A".

[0062] In some embodiments, the terminal device 110 may present a cancel generation control and a generation control in two cases: when a content element is generated and when it is not generated. For a content element in at least one group of content elements in the first area that is not generated, the terminal device 110 may present a generation control associated with that content element, and may determine that a generation trigger for the content element has been received in response to receiving a trigger for that generation control. In response to receiving a generation trigger for that content element, the terminal device 110 may present a group of next-level content elements generated based on that content element in the first area, cancel the presentation of the generation control associated with that content element, and present a cancel generation control associated with that content element. In response to receiving a trigger for the cancel generation control, the terminal device 110 may cancel the presentation of a group of next-level content elements generated based on that content element.

[0063] In some embodiments, if some content elements in at least one group of content elements are generated based on web page content, the terminal device 110 may also display web page links associated with the relevant content elements in a first area. For example, see reference... Figure 2D If the set of content elements included in card 260 is generated based on webpage content, terminal device 110 can display webpage links associated with each content element in this set of content elements. For example, terminal device 110 can switch to displaying the webpage used to generate the corresponding content element in response to receiving a trigger for a webpage link.

[0064] In some embodiments, terminal device 110 may, in response to the selection of at least one content element from at least one set of content elements in a first area, present the selected at least one content element in a second area of ​​a first interface. Terminal device 110 may receive the selection of at least one content element in any suitable manner. For example, terminal device 110 may present at least one card in the first area for presenting at least one set of content elements, each card comprising a set of areas, each area for presenting one content element. Terminal device 110 may, in response to receiving a trigger on a certain area, determine that a selection of the content element corresponding to that area has been received.

[0065] In some embodiments, the terminal device 110 may also present a selection control in a first area associated with each content element in at least one set of content elements. For a content element in the first area that is not selected, the terminal device 110 may determine that a selection of a second content element has been detected in response to the triggering of the selection control associated with that content element. As an example, see [reference needed]. Figures 2C to 2I Terminal device 110 can determine that it has received a selection of content element "Topic A" and a selection of content element "Topic C" in response to receiving a trigger of a selection control associated with content element "Topic A" and a selection control associated with content element "Topic C" in card 250.

[0066] Accordingly, for a selected content element from at least one set of content elements in the first region, the terminal device 110 can determine, in response to the triggering of a selection control associated with that content element, that a selection cancellation of the second content element has been detected. In some embodiments, the selection control is presented with different visual styles depending on whether the corresponding content element is selected or not. For example, see reference... Figure 2A and Figure 2DTerminal device 110 can present the selection control in the visual style shown in example interface 200A when the content element "Theme A" is not selected, and can present the selection control in the visual style shown in example interface 200D (i.e., the visual style filled with black) when the content element "Theme A" is selected.

[0067] In some embodiments, the terminal device 110 may present a selection cancellation control and a selection control respectively, depending on whether a content element is selected or not. For an unselected content element among at least one group of content elements in the first area, the terminal device 110 may present a selection control associated with that content element, and may determine that a selection of the content element has been received in response to a trigger on the selection control. The terminal device 110 may, in response to receiving a selection of the content element, cancel the presentation of the selection control associated with that content element, and present a selection cancellation control associated with that content element. The terminal device 110 may, in response to receiving a trigger on the selection cancellation control, determine that a selection cancellation of the element has been detected.

[0068] Terminal device 110 can display at least one selected content element in the second area. The first and second areas can be distributed in any suitable layout within the first interface. For example, the first area can be located on the left side of the first interface, and the second area can be located on the right side of the first interface, with the first and second interfaces displayed in parallel. Alternatively, the second area can be partially overlaid on the first area at an appropriate location. In this case, the first area can occupy the entire area of ​​the first interface, and the second area can, for example, be overlaid on the right side of the first area.

[0069] In some embodiments, the terminal device 110 may display a switching control associated with the second region. As an example, refer to... Figures 2A to 2ITerminal device 110 may include region 230, which illustrates an example of a second region. Terminal device 110 may associate a presentation switching control 232 with region 230. When region 230 of terminal device 110 is displayed in a minimized state (as shown in example interfaces 200B and 200F, where terminal device 110 may only display the name of region 230), terminal device 110 may, in response to receiving a trigger on the switching control 232, switch region 230 to an expanded state (as shown in example interfaces 200C to 200E, and example interfaces 200G to 200I, where terminal device 110 may display the entire region 230). Correspondingly, when region 230 is displayed in an expanded state, terminal device 110 may also, in response to receiving a trigger on the switching control 232, switch region 230 to a minimized state. Thus, the user can determine whether to display the second region based on their needs, ensuring the simplicity of the first interface.

[0070] The second area may include at least one selected content element. In some embodiments, if no content element is selected, the second area may include a prompt message to prompt the user to select a content element. The prompt message may include text, images, icons, or any suitable type of content. As an example, if no content element is selected, the terminal device 110 may display the prompt text "Please select a content element for generating media content" in the second area.

[0071] Terminal device 110 can determine the presentation order of at least one content element in a second area based on at least one of the hierarchy of at least one content element and the time order in which at least one content element was selected, and present at least one content element in the second area according to the determined presentation order. As an example, for multiple content elements at the same hierarchy, terminal device 110 can determine the presentation order of the multiple content elements in the second area based on the time order in which the multiple content elements were selected.

[0072] refer to Figure 2C Terminal device 110 can determine, in response to the fact that content element "Topic A" is selected first and content element "Topic C" is selected later, that the presentation order of content element "Topic A" in area 230 is earlier than the presentation order of content element "Topic C". For example, refer to... Figure 2D For content elements "Content B" and "Content F" at the same level, the terminal device 110 can determine that the presentation order of content element "Content B" is earlier than the presentation order of content element "Content F" in response to the fact that content element "Content B" is selected first and content element "Content F" is selected later.

[0073] As an example, for multiple content elements at different levels, terminal device 110 can determine the presentation order of the multiple content elements in the second area based on the level of each content element. (See reference) Figure 2D Since the selected content element "Content B" corresponds to the next level below the levels of content elements "Topic A" and "Topic C", the terminal device 110 can determine that the presentation order of content element "Content B" is later than the presentation order of content elements "Topic A" and "Topic C".

[0074] For example, refer to Figure 2F and Figure 2G Since the selected content element "Content L" in the example interface 200F belongs to a group of content elements corresponding to card 270, and the level corresponding to content element "Content L" is later than the levels corresponding to content elements "Topic A", "Topic C", "Content B", and "Content F", the terminal device 110 can determine that the presentation order of content element "Content L" is later than the presentation order of content elements "Topic A", "Topic C", "Content B", and "Content F" (for example, the presentation order shown in example interface 200G).

[0075] It should be noted that the terminal device 110 can also use other methods to determine the presentation order of at least one content element in the second area. For example, if multiple content elements belong to the same group of content elements, the terminal device 110 can determine the presentation order of these multiple content elements based on their order within that group. (See reference) Figure 2C Terminal device 110 can determine that the presentation order of content element "Theme A" in area 230 is earlier than the presentation order of content element "Theme C" in card 250, in response to the fact that content element "Theme A" is located before content element "Theme C" in card 250.

[0076] Terminal device 110 can also determine the presentation order of multiple content elements based on various factors. For example, if at least one selected element includes multiple content elements at the same level but from different groups of content elements, terminal device 110 can determine the presentation order of the multiple elements in the second area based on the order of the preceding content elements in the respective group of content elements to which each of these multiple content elements belongs. For example, refer to... Figure 2EThe selected content elements include content elements "Content B" and "Content F" which are at the same level but from different groups of content elements. Content element "Content B" belongs to a group of content elements generated based on content element "Topic A," while content element "Content F" belongs to a group of content elements generated based on content element "Topic B." Since content element "Topic A" is listed before content element "Topic B" in card 250, terminal device 110 can determine that the presentation order of content elements from card 260 is earlier than that from card 262; that is, the presentation order of content element "Content B" is earlier than that of content element "Content F." Considering the hierarchy, the presentation order of content element "Content B" is also later than the presentation order of content elements "Topic A" and "Topic C."

[0077] For example, refer to Figure 2G and Figure 2H Compared to Figure 2E The selected content element may also include content element "Content D". The terminal device 110 may determine that the presentation order of content element "Content D" is later than the presentation order of content element "Content B" in response to the fact that content element "Content D" and content element "Content B" come from the same group of content elements and are selected after content element "Content B". It may also determine, with reference to the above description, that the presentation order of content element "Content D" is between the presentation order of content element "Content B" and the presentation order of content element "Content F".

[0078] Terminal device 110 can generate media content based on at least one content element in the second area in response to a content generation request acting on the second area. For example, terminal device 110 can display a content generation control in the second area. If the second area includes at least one selected content element, terminal device 110 can determine that a content generation request acting on the second area has been received in response to receiving a trigger on the content generation control, and then generate media content based on the selected content element in response to the content generation request.

[0079] In some embodiments, terminal device 110 supports copying at least one selected content element. Terminal device 110 may, for example, present a copy control in a second area. For example, as shown in example interfaces 200C to 200E and example interfaces 200G to 200I, area 230 may include a copy control 234. Terminal device 110 may determine that a copy request for at least one content element presented in the second area has been received in response to receiving a trigger on the copy control. Terminal device 110 may, in response to receiving a copy request for at least one content element presented in the second area, copy all of the at least one content element. Terminal device 110 may also, for example, present a prompt indicating that at least one content element has been copied.

[0080] In some embodiments, terminal device 110 supports editing of at least one selected content element. Terminal device 110 can, in response to an editing operation on at least a portion of the content of the at least one content element, determine the at least one content element that has been edited, and can, in response to a content generation request acting on a second area, generate media content based at least on the at least one edited content element. Editing operations include any appropriate operations such as adding, deleting, or replacing, and this disclosure does not limit such operations. Taking at least one content element as at least one text paragraph as an example, terminal device 110 can, in response to an editing operation on at least a portion of the text, determine the at least one edited text paragraph, and subsequently generate media content based on the at least one edited text paragraph.

[0081] In some embodiments, for any of the at least one selected content element, regardless of whether the content element has been edited, the terminal device 110 may, in response to detecting a deselection of the content element in a first area, determine to cancel the selection of the content element and de-present the content element in a second area. In some embodiments, the terminal device 110 may also determine whether the content element has been edited.

[0082] If the content element has not been edited in the second area, the terminal device 110 can, in response to detecting a deselection of the content element in the first area, determine to deselect the content element and de-present the content element in the second area. If the content element has been edited in the second area, the terminal device 110 can, in response to detecting a deselection of the content element in the first area, determine to deselect the content element and maintain the presentation of the content element in the second area. That is, the terminal device 110 can present the content element in the first area with an unselected visual style, and maintain the presentation of the edited content element in the second area.

[0083] In some embodiments, the terminal device 110 may, in response to a content generation request acting on the second area, present a content generation panel, which includes at least a setting control for configuring the duration of the media content to be generated. For example, if the media content is text, the duration of the media content can be the duration of the text being played aloud. If the media content is video, the duration of the media content can be the duration of the video content.

[0084] The setting control can be any suitable type of control. For example, the setting control may include multiple options corresponding to multiple durations. The terminal device 110 can, in response to receiving a selection of an option, determine that a duration setting has been received and determine the duration of the media content as indicated by the selected option. Alternatively, the setting control may include an input box through which the terminal device 110 can receive duration input by the user. The terminal device 110 can determine the duration of the media content via the setting control and then generate the media content based on at least one content element in the second area and the determined duration.

[0085] In some embodiments, the content generation panel may further include an input box through which the terminal device 110 can receive restriction information for the media content to be generated. In response to receiving the restriction information via the input box, the terminal device 110 can generate media content based on at least one content element in the second area, the determined duration, and the restriction information. The restriction information may, for example, be used to restrict the type, style, or domain of the media content to be generated, or any other appropriate content. It is understood that the terminal device 110 can also generate media content based on any other appropriate information. For example, if a user account is bound, the terminal device 110 can also generate media content based on information associated with the user account.

[0086] In some embodiments, the terminal device 110 may present a third interface in response to a content generation request acting on the second area, and may present the media content in the third interface in response to the completion of media content generation. In some embodiments, the terminal device 110 may directly present the entire media content in the third interface in response to the complete generation of the media content. In some embodiments, the media content may be generated in a streaming manner, and the terminal device 110 may stream the generated media content and stream the acquired media content in the third interface.

[0087] As an example, refer to Figures 2I to 2KIn the example interface 200I, area 230 includes a content generation control 236. Terminal device 110 can, in response to receiving a trigger on the content generation control 236, determine that a content generation request has been received for the second area. Terminal device 110 can, in response to receiving the content generation request, present a content generation panel 280. Content generation panel 280 can include multiple options (i.e., options 281 to 284) corresponding to multiple durations. Terminal device 110 can, in response to receiving a selection of an option, determine that a duration setting has been received and determine the duration of the media content as indicated by the selected option.

[0088] The content generation panel 280 may further include an input box 285, through which the terminal device 110 can receive restriction information for the media content to be generated. In response to receiving restriction information via the input box, the terminal device 110 can generate media content based on at least one content element in the second area, a determined duration, and the restriction information. Alternatively, the terminal device 110 can generate media content based on at least one content element in the second area and a determined duration without receiving restriction information from the input box.

[0089] The content generation panel 280 may also include a generation control 286. In response to receiving a trigger on the generation control 286, the terminal device 110 determines that a content generation request has been received acting on the second area. The terminal device 110 may display an example interface 200J or an example interface 200K, which illustrate examples of a third interface. Example interfaces 200J and 200K include areas 291 and 292. Area 291 includes an area 293 for displaying at least one selected content element and an area 294 for displaying settings information associated with the media content to be generated.

[0090] Area 293 can correspond to the second area of ​​the first interface, and area 294 can correspond to the content generation panel. Area 294 may include setting controls for setting the duration of media content (e.g., multiple options corresponding to multiple durations), an input box 295 for receiving restriction information, and a generation control 296. In some embodiments, the selected option can be highlighted in area 294. For example, if the duration of the media item is determined to be 3 minutes, the terminal device 110 can highlight the option "3min" in area 294. This allows the user to intuitively understand the duration of the media content.

[0091] Area 292 includes a prompt box 297, which can display a prompt message indicating that media content is currently being generated. This prompt message may include, for example, the prompt text "Generating content…" shown in example interface 200J. Area 292 may also include a stop control 298, which the terminal device 110 can use to stop media content generation in response to receiving a trigger on the stop control 298. For example, the terminal device 110 may display example interface 200J in response to no media content being acquired, and may display example interface 200K in response to at least a portion of the media content being acquired.

[0092] In summary, according to the various embodiments of this disclosure, a first interface can be presented in response to a content expansion request including instruction information. A first area of ​​the first interface can present at least one set of content elements, and a second area can present at least one content element selected by the user from the at least one set of content elements. Media content can be generated based on at least one content element in the second area. In this way, a large number of content elements can be provided to the user based on interaction, helping the user to expand their thinking. Media content can be generated automatically, which helps improve the efficiency of media content generation.
