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.

Abstract: Disclosed is an apparatus and method of generating a VR sickness prediction model. A method of generating a VR sickness prediction model according to the present disclosure includes: displaying virtual reality content on a display unit; detecting first VR sickness information of a user who experiences the virtual reality content using a sensor; determining second VR sickness information using a user input that is input from the user in response to a request for inputting a degree of VR sickness for the virtual reality content; performing machine learning based on supervised learning using VR sickness-inducing factors for the virtual reality content, the first VR sickness information, and the second VR sickness information; and determining a correlation between the VR sickness-inducing factors and a list of VR sickness symptoms on a basis of the performed machine learning.

Abstract: Provided is a method of generating multi-view immersive content. The method includes obtaining a multi-view background image from a plurality of cameras arranged in a curved shape, modeling the obtained multi-view background image to generate a codebook corresponding to the multi-view background image, obtaining a multi-view image including an object from the plurality of cameras and separating a foreground and a background from the obtained multi-view image by using the generated codebook, and synthesizing the object included in the separated foreground with a virtual background to generate multi-view immersive content.
