Abstract: A method for estimating a three-dimensional (3D) hand pose in an augmentation system is provided. The augmentation system receives a camera focal length and camera images from a device with a single RGB camera, outputs a 3D hand pose estimation result by performing hand bounding box detection and hand landmark detection from the camera images using one machine learning model, and augments the 3D hand pose estimation result on a display.

Abstract: Provided is a method and device for outputting a large-capacity 3D model for an augmented reality (AR) device. A method of outputting a large-capacity 3D model for an AR device includes generating a multi-texture and a 3D mesh based on a multi-view image, generating a 3D model using the multi-texture and the 3D mesh, and transmitting, to the AR device, an image of the 3D model in a view, to which a camera of the AR device is directed, according to camera movement and rotation information of the AR device, and the AR device outputs the image in the view, to which the camera is directed.

Abstract: A computing device adapts an interface for extended reality. The computing device collects user information and external environment information when a user loads a virtual interface to experience extended reality content, and selects a highest interaction accuracy from among one or more interaction accuracies mapped to the collected user information and external environment information. The computing device determines content information mapped to the highest interaction accuracy, and reloads the virtual interface based on a state of the virtual interface that is determined based on the determined content information.
