Abstract
Gaze tracking data representing a user's gaze is analyzed to determine one or more regions of interest. One or more gaze tracking error parameters are determined from the gaze tracking data including a rate of rotation of a user's eye with respect to one or more axes. An error in a fixation of the user's eye on a particular region of interest is determined. Adjusted foveation data is determined representing an adjusted size and/or shape of one or more regions of interest in one or more images to be subsequently presented to the user based on the one or more gaze tracking parameters. The one or more transmitted images are selectively compressed so that fewer bits are needed to transmit data for portions of an image outside the one or more regions interest than for portions of the image within the one or more regions of interest.
