Abstract: Disclosed herein is an apparatus for analyzing efficiency of virtual task performance of a user interacting with eXtended Reality (XR). The apparatus includes memory in which at least one program is recorded and a processor for executing the program. The program may perform generating user interaction feature information from sensor information of a virtual reality (VR) device, calculating the quality of experience of a user as the values of multiple experience indices based on the feature information by applying a machine-learning model, and evaluating an experience based on a result of mapping the values of the multiple experience indices to generated metrics in order to analyze the effectiveness of the VR experience of the user.
