1. A method of adapting a display, comprising:

  • collecting image data at a frame rate with a video image sensor;

    presenting output on a display screen, the output including one or more frames of the image data;

    tracking a gaze pattern of a user viewing the display screen output;

    mapping the gaze pattern to physical locations of the display screen;

    determining, based on the mapping, a sub-region of the display screen being attended to by the user, the determining performed while collecting additional frames of image data with the video sensor, and performed periodically at a frequency below the frame rate, or in response to an indication the user blinked, or a gaze shift is above a threshold;

    transmitting the additional frames of the image data to the computing platform with a greater bit rate for a first portion of each additional frame of the image data corresponding to the attended sub-region than for a second portion of each additional frame of the image data corresponding to the unattended sub-region;

    assembling, with a computing platform, the first and second portions of the additional frames into reconstructed image data frames; and

    updating the output on the display screen with the reconstructed image data frames.
