The server 20 may provide the client 10 with data to be loaded of item basic information corresponding to sub-item objects in response to a current trigger operation of a user, so that the client 10 displays the item basic information corresponding to the sub-item objects based on the data to be loaded.
As an example, the server 20 may be but not limited to an independent server, a server cluster or a distributed system composed of multiple physical servers, or one or more of cloud servers or the like which provide basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, network services, cloud communications, middleware services, domain name services, security services, big data and artificial intelligence platforms and the like. The client 10 and the server 20 may be directly or indirectly connected through wired or wireless communication, which is not limited in the embodiment of the present disclosure.
The method for displaying item information according to the embodiment of the present disclosure may be executed by an apparatus for displaying item information. The apparatus may be integrated in an electronic device such as a terminal in the form of hardware or software, or may be implemented by the terminal alone, or may be implemented by the terminal and the server cooperatively.
At S201, item category information corresponding to a combined item object and an interaction operation control for viewing basic information of sub-items are displayed on an item display interface of a live broadcast room. The combined item object includes at least two sub-item objects of the same category.
In the embodiment of this specification, the anchor user uses an anchor terminal to record a live broadcast and interact with an audience user. The audience user uses the audience terminal to watch the live broadcast and interact with the anchor user. The server is used to transmit in real time the live video recorded by the anchor user to the audience user, and transmit interaction data between the audience user and the anchor user. In the process of e-commerce live broadcast, the anchor user sells cooperative items in the live broadcast. The audience terminal can display item category information corresponding to a combined item object and an interaction operation control for viewing basic information of sub-items on an item display interface of a live broadcast room, for the audiences to watch.
The live broadcast interface is often set with an anchor video area and an interaction area. The item display interface may be an item display area set in the live broadcast interface. The item display interface can also be an interface independent of the live broadcast interface, and the interface style adopted by the item display interface can be a notification bar, a pop-up window, a floating window, and the like.
The combined item object includes at least two sub-item objects of the same category. For example, the item category A is a hotpot coupon and the sub-item objects included in the combined item object A have a sub-item object 1 indicating a brand A hotpot coupon, a sub-item object 2 indicating a brand B hotpot coupon and a sub-item object 3 indicating a brand C hotpot coupon. When the anchor user explains the item category A, the audience terminal displays the item category information corresponding to the combined item object A and the interaction operation control for viewing the basic information of the sub-items on the item display interface of the live broadcast room.
The item category information corresponding to the combined item object may be information describing the combined item object, which may include but not limited to at least one of an item category name, an image and a video indicating the item category, price range information, an activity title, an activity introduction, etc. The interaction operation control for viewing the basic information of the sub-items is configured to receive a trigger operation of the audience user and allow the user to view the sub-item object (belonging to the combined item object). In an example, the item category information corresponding to the combined item object may be displayed in a first preset area of the item display interface. The item category information includes at least one of an item category name, an image and a video indicating the item category. The interaction operation control for viewing basic information of sub-items is displayed in a second preset area of the item display interface. the item category information corresponding to the combined item object and the interaction operation control for viewing the basic information of the sub-items are respectively displayed in different areas of the item display interface, which provides a simple and intuitive display interface of the combined item object. When there is more than one piece of item category information corresponding to the combined item object, the pieces of information can be displayed in one place in the first preset area, which is different from the second preset area where the interaction operation control is displayed, which can improve convenience of the audience users to find a target on the item display interface, thus improving the operation efficiency of viewing the items during the e-commerce live broadcast.
As shown in
In an embodiment, before displaying item category information corresponding to the combined item object and the interaction operation control for viewing basic information of sub-items on the item display interface of the live broadcast room, the method further includes: detecting content information of an anchor explaining the items; and determining the combined item object based on the content information. During the process of e-commerce live broadcast, the anchor user may explain items to be sold one by one, the audience terminal may detect the content information of the anchor explaining the items according to a live video transmitted by the server in real time and determine the combined item object according to the content information, so as to request the server for data to be loaded of the item category information corresponding to the combined item object or query the data to be loaded from data pre-stored locally. In this way, the timeliness and accuracy of locating the combined item object in conjunction with the explanation of the anchor user can be improved. Taking situations into account, such as a network state, a device state, etc., a situation where moments of receiving live videos that the anchor user is instructed to explain a certain items to be sold may be different for different audience terminals, actively detecting the explained content information and determining the combined item object by the audience terminal may ensure live viewing experience of the specific audience terminal.
In practical applications, the combined item object may be constructed by the anchor user through a user interface of the anchor terminal or may also be constructed by a staff of the platform that provides e-commerce live broadcast services on the user interface provided by the platform. During the process of commercial live broadcast, the anchor uses the combined item object that has been constructed. Since the sub-item objects in the combined item object are from cooperative merchants, items from different cooperative merchants need to be combined in constructing a combined item object, the items identifiers need to be set, and information such as product content, an stock keeping unit (SKU), a price, an applicable city, an applicable store, a purchase policy, a validity period need to be obtained. Generally, the refund policy for the combined item object may need to be consistent with each other.
Since the sub-item objects in the combined item object are from cooperative merchants, different cooperative merchants may provide different applicable region conditions of sub-items and the applicable region conditions of sub-items from different cooperative merchants may exist some intersection regions. For example, the applicable regions of applicable region condition 1 are regions 1 to 3, and the applicable regions of applicable region condition 2 are regions 3 to 4, then the region 3 is the intersection region corresponding to the two applicable region conditions. In an example, the cooperative merchants may be merchants with chain stores in different regions, and an entrance to “publish a combined item object” may be provided with the cooperative merchants. The combined item object may be constructed by the cooperative merchants, and the anchor user may use the combined item object that has been constructed in the process of e-commerce live broadcast. The information about the related items that the cooperative merchant needs to upload may include an item name, an item header image, and an associated video, etc.
Compared with a single item object, the combined item object realizes aggregation of multiple item objects indicating the same item category. The combined item object can make up for applicable region limitations of the single item object and the items that are more applicable or interested may displayed to audience users in different regions, for example, hotpot coupons that are more in line with tastes are displayed to audience users in different regions. Referring to
At S202, in response to a triggering operation of the interaction operation control, a target sub-item object matching specified geographic information of an audience terminal is determined from the at least two sub-item objects.
In the embodiment of this specification, the trigger operation of the interaction operation control indicates that the basic information of the sub-items needs to be viewed. The trigger operation of the interaction operation control may include but are not limited to, a clicking operation, a sliding operation, a gesture operation, an expression trigger operation, a voice trigger operation, and the like. The combined item object includes at least two sub-item objects of the same category. The sub-item object that matches the specified geographic information of the audience terminal may be one sub-item object, two sub-item objects, or multiple sub-item objects determined from the sub-item objects indicating the same item category in the combined item object. When the sub-item object matching the specified geographic information of the audience terminal is determined from the combined item object, it can be determined according to applicable geographic information carried by the sub-item object in the combined item object. The applicable geographic information may come from applicable region conditions of the cooperative items indicated by the sub-item object (for example, the applicable region for the applicable region conditions of the cooperative item 1 is region A), or may also come from a recommended usage region of the cooperative item indicated by the sub-item object (for example, the recommended usage region of the cooperative item 2 is region B; when the cooperative item 2 is a ski cap, the region that is inconvenient to carry out skiing is a region that is not recommended for the cooperative item 2).
The following may introduce how to determine the target sub-item object in combination with two types of the specified geographic information of the audience terminal.
1) The specified geographic information is current geographic information of the audience terminal, in response to the trigger operation of the interaction operation control, determining the target sub-item object matching the specified geographic information of the audience terminal from the at least two sub-item objects includes the following steps at S301-S303 as shown in
At S301, applicable geographic information corresponding to each of the at least two sub-item objects is obtained.
At S302, target applicable geographic information matching the specified geographic information is determined from the applicable geographic information corresponding to each of the sub-item objects.
At S303, a sub-item object corresponding to the target applicable geographic information is determined as the target sub-item object.
The current geographic information can be obtained by the audience terminal with the help of a location based service (LBS), and the current geographic information may be positioning information obtained based on the global positioning system (GPS), positioning information obtained based on the wireless communication technology (Wi-Fi), and positioning information obtained based on the Internet protocol address (IP address). The current geographic information may be in the form of geographic coordinates, region labels (such as labels for city A, labels for northern regions), and the like. Alternatively, the current geographic information may also come from the region and city that the audience user fills in the user profile.
The Applicable geographic information may be used as a necessary parameter for the sub-item object when constructing a combined item object. The applicable geographic information of the sub-item object may come from the applicable region conditions of the sub-items provided by the cooperative merchants. The applicable geographic information may be in the form of region labels.
For example, the applicable geographic information of the sub-item object 4 in the combined item object B is city A, the applicable geographic information of the sub-item object 5 is city B, and the applicable geographic information of the sub-item object 6 is city C. The current geographic information as the specified geographic information of the audience terminal is {aaa˜bbb in east longitude, ccc˜ddd in north latitude}. When the specified geographic information of the audience terminal falls within a geographic coordinate range of city A, then city A is the target applicable geographic information, the sub-item object 4 is the target sub-item object. Correspondingly, the audience terminal displays the item basic information of the sub-item object 4 as the target sub-item object.
The sub-item object that matches the current geographic information can be enjoyed by the audience user after purchase, and are more suitable for personal living habits of the audience user. Displaying the item basic information of the sub-item object matching the current geographic information to the audience user can improve the accuracy of displaying the items for sale to the audience user. Especially for local daily items (such as consumption coupons for restaurant merchants, consumption coupons for entertainment merchants, etc.), such items often need to be consumed in stores after purchase. In other words, such items have geographical restrictions on their usage, e.g., there is no merchant store that serves the type of items in certain regions, or the same merchant has configured different restrictions for this type of items in different regions. The audience users in the live broadcast room can be from different regions, and displaying the basic item information of the sub-item objects that match the current geographic information to the audience users may avoid displaying items with geographic usage restrictions to the audience users, may provide the audience users with a personalized, high-quality shopping environment in the live broadcast room with low interference information content, thus realizing the function of accurately selling cross-region consumption coupons in a cross-region live broadcast.
Further, the audience terminal can skip the display of the combined item object, so that the sub-item objects that match the current geographic information are directly displayed. The audience terminal can detect the content information of the anchor explaining for the items according to the live video transmitted by the server in real time, and then determine the combined item object according to the explained content information, so as to request the server for data to be loaded for the item basic information of the sub-item objects that match the current geographic information (in the combined item object) or to query the data to be loaded from data pre-stored locally.
2) The specified geographic information is geographic information indicated by the trigger operation, in response to the trigger operation of the interaction operation control, determining the target sub-item object matching the specified geographic information of the audience terminal from the at least two sub-item objects includes the following steps at S401-S403.
At S401, applicable geographic information corresponding to each of the at least two sub-item objects is obtained.
At S402, target applicable geographic information matching the specified geographic information is determined from the applicable geographic information corresponding to each of the sub-item objects.
At S403, a sub-item object corresponding to the target applicable geographic information is determined as the target sub-item object.
The geographic information indicated by the trigger operation indicates that geographic information dimension of the items to be viewed is limited when the audience user chooses to view the items. In an embodiment, the geographic information indicated by the trigger operation may be determined by detecting geographic information where the trigger operation is located. The geographic information indicated by the trigger operation may be in the form of geographic coordinates, region labels (such as labels for city A, labels for northern regions), and the like. For the steps at S402-S403 here, reference may be made to the above steps at S302-S303, which may not be elaborated here.
The sub-item objects that match the geographic information indicated by the trigger operation satisfies real-time demand of the audience users when selecting the items to check based on the trigger operation, and improves convenience of the audience users to check the items in the geographic information dimension. Especially for local daily items (such as consumption coupons for restaurant merchants, consumption coupons for entertainment merchants, etc.), such items often need to be consumed in stores after purchase. In other words, such items have geographical restrictions on their usage. The audience users in the live broadcast room can be from different regions, such as, business travelers, people planning to travel, etc. This can improve the convenience and efficiency of viewing and purchasing local lifestyle items in the destination.
At S203, basic item information corresponding to the target sub-item object is displayed on the item display interface.
In the embodiment of this specification, the item display interface on the audience terminal displays the basic item information corresponding to the target sub-item object. The item basic information of the sub-item object may include a first type of item basic information and a second type of item basic information. The first type of item basic information may include but is not limited to at least one of an item brand, an item name, an item image, an item video and the like. The second type of item basic information may include but is not limited to at least one of an item price, an item stock keeping unit (SKU), applicable city information, applicable store information, in-store consumption guidance information, and the like.
As shown in
In an implementation, as shown in
At S501, the item basic information corresponding to the target sub-item object is displayed on an association interface of the item display interface.
The association interface of the item display interface can be a secondary page of the item display interface. At this time, the efficiency of switching from the item display interface as a primary page to the secondary page is relatively high. The association interface may also be a page whose dependence on the running environment is lower than dependence of the item display interface on the running environment, which can reduce the overhead of running resources and ensure the reliability and stability of the system performance.
In an example, the first type of item basic information corresponding to the target sub-item object may be displayed in the first preset area of the association interface. The first type of item basic information includes at least one of an item brand, an item name, an item image and an item video. The second type of item basic information corresponding to the target sub-item object may be displayed in the second preset area of the association interface. The second type of item basic information includes at least one of an item price, an item SKU, applicable city information, applicable store information and in-store consumption guidance information.
Here, the above-mentioned description may be referred, the “item SKU” can be a number of remaining saleable coupons for the A brand hotpot coupons, e.g., 100; the “applicable city information” can be “A city”; the “applicable store information” can be the “A store”. When there are multiple pieces of item basic information of the sub-item object, the item basic information are divided to the first type of item basic information and the second type of item basic information. The first type of item basic information may be displayed in one place of the first preset area, which can be distinguished from the second preset area where the second type of item basic information is displayed. In this way, it can improve convenience for the audience users to find a target in the association interface and thus improve the operation efficiency of learning about and buying items during the e-commerce live broadcast process.
For “displaying the item basic information of the target sub-item object”, display sequence information indicated by the trigger operation may be determined first; the item basic information corresponding to the target sub-item object is then displayed on the association interface based on the display sequence information. The audience users may select a limitation to the display sequence information of the sub-items to be viewed. For example, after selection of the audience user, the sub-items are displayed in a sequence of “low price first” or in a sequence of “sales volume first”. When the number of target sub-item objects is one, the item basic information of the target sub-item object can be directly displayed. When the number of target sub-item objects is greater than or equal to 2, a display reference item may be first determined based on the display sequence information, for example, the display reference item “item price” for display sequence information corresponding to “low price first”. The items price of each target sub-item object is determined based on the item basic information of each target sub-item object, and the item basic information of the target sub-item objects are then ranked in an ascending order of item prices for display.
The target sub-item object is displayed according to the display sequence information indicated by the trigger operation, which satisfies real-time demand of the audience user when selecting the items to view based on the trigger operation. The top item displayed according to the display sequence information may fall into an interested range of audience users, which can improve the efficiency of audience users in finding suitable items and improve the shopping experience of audience users in the live broadcast room.
With the method for displaying item information according to the above-mentioned embodiment, sub-item objects that match the specified geographic information of the audience terminal may be displayed to the audience when a certain item category is explained in the live broadcast room, so as to avoid that the item objects displayed to audiences are not applicable or audiences are not interested in these item objects, thus realizing accurate display of the items to be sold. In this way, the sub-item objects with different applicable region conditions can be constructed as combined item objects according to the indicated item categories, so that the sub-item objects with different applicable region conditions can be displayed in the live broadcast room at the same time, thus improving the experience of audiences viewing the e-commerce live broadcast and shopping in the live broadcast room, and improving a traffic utilization rate of the live broadcast room.
