Abstract: A service providing method implemented by a service system that includes a service server and a service intermediate terminal for providing application program interface (API) services, the service providing method includes: transmitting service usage specification data for input to a large language model (LLM) operating on a service request terminal to enable the LLM to generate a service request that includes identification data indicating a target API service to be accessed and input data for accessing the target API service, and transmit the service request to the service intermediate terminal, the target API service being one of the API services; and upon receiving the service request from the service intermediate terminal, accessing, by the service intermediate terminal, the target API service according to the identification data and inputting the input data to the target API service, so as to provide services.

Abstract: A method for providing a set of augmented reality (AR) operating instructions for operating an apparatus, the apparatus having a two-dimensional (2D) barcode disposed thereon. The method is implemented using an AR device and includes steps of: capturing an image of the 2D barcode to obtain three-dimensional (3D) animation data associated with the AR operating instructions; obtaining a location of the 2D barcode and an orientation of the 2D barcode based on the image of the 2D barcode, the location of the 2D barcode being defined with respect to a 3D coordinate system using the AR device as a spatial anchor, the orientation indicating a direction in which the 2D barcode faces with respect to the 3D coordinate system; and presenting the AR operating instructions based on the location of the 2D barcode, the orientation of the 2D barcode and the 3D animation data.

Abstract: A method for displaying a virtual image to a user is implemented by a computing device. The method includes to first obtain an initial position of the user, and define a reference point at the initial position of the user. Then, the computing device obtains a user position of the user, and determines whether a distance between a position of the reference point and the user position is greater than a threshold. If the distance is greater than the threshold, the computing device moves the position of the reference point to a reference position that is at most the threshold away from the user position. Finally, the computing device obtains a display position as a relative position based on the position of the reference point, and displays the virtual image at the display position.

Abstract: A method for providing service-related data includes: obtaining header information associated with a merchant based on registration information associated with the merchant, the registration information at least including a location of the merchant; based on product data associated with the merchandise, obtaining merchandise-related data associated with a merchandise provided by the merchant; obtaining content information based on the product data and the merchandise-related data; generating the service-related data using the header information and the content information; and transmitting the service-related data to a server as an entry of to-be-searched service-related data to enable the server to store the entry of to-be-searched service-related data in a data storage.
