WEARABLE DEVICE FOR CHANGING FRAME RATE ASSOCIATED WITH FOVEATED RENDERING ACCORDING TO MOVEMENT SPEED OF GAZE POSITION AND METHOD THEREOF

Abstract: according to an embodiment, a wearable device obtains information with respect to a gaze position by using at least one sensor. the wearable device, based on identifying a movement speed of the gaze position slower than a reference speed using the information, obtains a plurality of first images corresponding to a display area of the display system. the wearable device obtains a second image corresponding to a foveated area that is specified within the display area based on the gaze position. the wearable device performs foveated rendering with respect to a screen to be displayed through the display area by combining the second image to each of the plurality of first images that is upscaled based on a size of the display area.
