Claim 18:
19. A method to determine a target point of regard associated with a user of a display, the method comprising:
receiving a target image data associated with the user from a camera coupled with the display, wherein the target image data includes a target eye patch image data associated with the user;
determining, using a convolutional neural network, the target point of regard associated with the target image data based on:
the target eye patch image data,
a plurality of aggregated gaze reference vectors, and
a plurality of reference image data associated with the user, the plurality of reference image data respectively associated with the plurality of aggregated gaze reference vectors,

wherein the target point of regard is determined within a predetermined threshold;
mapping the target point of regard onto the display;
determining a first blink associated with the target eye patch image data of the user, and a second blink associated with the target eye patch image data of the user;
determining a time difference between one or more of the following: a beginning of the first blink and a beginning of the second blink, an end time of the first blink and an end time of the second blink, and/or a first time during the first blink and a first time during the second blink;
determining a blink rate using the time difference; and
determining a probability of a blink during an image capture, based on the blink rate.
