Use of eye tracking to adjust region-of-interest (roi) forcompressing images for transmission

A system, comprising:

• a processor;
• a memory;
• and
• computer-readable instructions embodied in the memory, the computer-readable instructions being configured to implement a method when executed, the method comprising:
• analyzing gaze tracking data representing a user's gaze with respect to one or more images transmitted to a user to determine one or more regions of interest;
• determining one or more gaze tracking parameters from the gaze tracking data including determining whether a saccade or blink is occurring or about to occur in the user's vision;
• generating adjusted foveation data 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, wherein each region of interest includes a foveal region;
• and
• adjusting compression of the one or more transmitted images so that fewer bits are needed to transmit data for portions of an image outside the one or more regions of interest than for portions of the image within the one or more regions of interest, wherein adjusting compression of the one or more transmitted images includes decreasing a size of the foveal region for a subset of the one or more images that are presented to the user during the saccade or blink.

A non-transitory computer-readable medium having computer-readable instructions embodied therein, the computer-readable instructions being configured to implement a method when executed, the method comprising:

• analyzing gaze tracking data representing a user's gaze with respect to one or more images transmitted to a user to determine one or more regions of interest;
• determining one or more gaze tracking parameters from the gaze tracking data including determining whether a saccade or blink is occurring or about to occur in the user's vision;
• generating adjusted foveation data 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, wherein each region of interest includes a foveal region;
• and
• adjusting compression of the one or more transmitted images so that fewer bits are needed to transmit data for portions of an image outside the one or more regions of interest than for portions of the image within the one or more regions of interest, wherein adjusting compression of the one or more transmitted images includes decreasing a size of the foveal region for a subset of the one or more images that are presented to the user during the saccade or blink.
