Abstract
Disclosed is a method of operating a stereoscopic image generating device communicating with a rendering server device including obtaining first tracking data by tracking a motion of a user during a reference time interval, obtaining second tracking data by tracking a viewpoint of the user during the reference time interval, providing the first tracking data to the rendering server device, receiving one or more focus image data corresponding to the first tracking data from the rendering server device, extracting one or more areas corresponding to the tracked viewpoint from each of the one or more focus image data based on the second tracking data, generating multifocal virtual reality (VR) image data by up-scaling the extracted one or more areas, and visually providing, by a display device of the stereoscopic image generating device, the multifocal VR image data to the user.
