Abstract

Systems and methods are disclosed for gaze tracking. A method includes receiving a video of a user taken by a front-facing camera of a device having a screen, receiving dimensions of the screen, parsing the video into a series of uniform-dimension video frame images, inputting the series of uniform-dimension video frame images to a pretrained artificial neural network, thereby extracting a plurality of features from the series of uniform-dimension video frame images to determine a set of internal spatial hierarchy features on each of the uniform-dimension video frame images, inputting each set of hierarchy features to a fully connected layer, the fully connected layer producing an intermediate physical estimate of the user's gaze location on the screen relative to the device camera in centimeters, determining a series of screen locations based on the intermediate physical estimate and the dimensions of the screen, and labeling the gaze location on the screen.
