Abstract: A method for offline-service multi-user interaction based on augmented reality (AR) includes scanning, by an AR client terminal of a user, an offline service label at an offline service site. Information of the offline service label is transmitted to a server terminal. Based on the information of the offline service label, the server terminal establishes a service group including the user and a second user that scanned the offline service label. In response to transmitting the information of the offline service label, service data is received from the server terminal. The service data includes information related to the user and information related to the second user. Based on the service data, a service interactive interface is outputted. The service interactive interface displays the information related to the user and the information related to the second user at a position corresponding to the offline service label in an AR scene.

Abstract: A smart meal ordering method comprises: conducting body sensing of a diner by a body sensing hardware of a smart meal ordering device; outputting a meal ordering interface by a display screen of a smart meal ordering device in response to sensing that the diner has taken a seat, and obtaining information of one or more dishes selected by the diner on the meal ordering interface; and in response to sensing that the diner has left the seat, sending a total price of the dishes and identification information of the smart meal ordering device to a server.

Abstract: In an implementation, one or more user interactions from a virtual reality (VR) device user for initiating a service in a VR scenario of a VR application are detected. One or more eye physiological characteristics of the VR device user are obtained for user identity authentication. The obtained one or more eye physiological characteristics are compared with one or more pre-stored eye physiological characteristics samples. The VR device user is authenticated if the one or more eye physiological characteristics match at least a portion of the one or more pre-stored eye physiological characteristics samples, and a server that provides and performs the service is communicated with.

Abstract: In an implementation, a virtual reality (VR) device includes a housing that has two openings. Each of the two openings hosts a camera lens and a nose groove. The VR device also includes one or more cameras distributed around each of the camera lenses for capturing one or more eye physiological characteristics of a VR device user.

Abstract: Responsive to receiving an indication of an input initiation, an input starting point and multiple virtual keys are presented in a virtual reality scenario. Each of the multiple virtual keys has at least one noninterfering path from the input starting point to each virtual key. The noninterfering path is not interfered by any other virtual keys. Displacement data of a focus of attention is received from sensing hardware. Responsive to determining that the focus of attention reaches the input starting point based on the displacement data, detection of a virtual key input is activated. Responsive to detecting that the focus of attention moves from the input starting point to a first virtual key, it is determined that the first virtual key is input; and the detection of the virtual key input is terminated.

Abstract: A virtual reality (VR) device presents a virtual element in a VR scenario of a VR application. An effective interaction region (EIR) of the virtual element is determined that the virtual element can effectively interact with. A trajectory of an operational focus of the VR application is determined based on a movement sensed by the VR device. The virtual element is selected if an interaction between the trajectory of the operational focus and the EIR satisfies one or more conditions for triggering a selection event of the virtual button.

Abstract: Interaction characteristics of a user interacting with a virtual reality (VR) terminal are obtained through preset sensing hardware in response to a request for execution of a target task requiring user identity verification. The obtained interaction characteristics of the user are compared with preset interaction characteristics of an authorized user of the VR terminal to verify identity of the user. The target task is executed and the user is authenticated as an identity-verified user of the VR terminal based on a successful user identity verification.

Abstract: A method for service control and user identity authentication includes recognizing a voice command of a virtual reality (VR) device user for initiating a service supported by a VR application, using a biometric sensor to collect one or more biometric characteristics of the VR device user, performing user identity authentication based on the collected one or more biometric characteristics, and communicating with a server that provides the service for performing the service if the user identity authentication is successful.

Abstract: Hand displacement data is received from sensing hardware and analyzed using a three-dimensional (3D) gesture recognition algorithm. The received hand displacement data is recognized as representing a 3D gesture. An operational position of the 3D gesture is calculated with respect to a 3D input graphical user interface (GUI). A virtual input element associated with the 3D input GUI and corresponding to the calculated operational position is selected. Input information corresponding to the selected virtual input element is read from the selected virtual element.
