1. A method for enabling projection of images from a 3D digital display, the method comprising:
obtaining face image data and eye region image data for a viewer within a field of view of at least one camera in proximity to a 3D-enabled digital display;
detecting face and eye landmarks for the viewer in one or more image frames based on the face image data;
determining head pose information based on the face image data and eye region image data;
determining eye tracking information for the viewer based on the face image data, eye region image data, and head pose information, the eye tracking information including:
a) a point of regard (POR) of each eye of the viewer;
b) eye state of each eye of the viewer;
c) gaze direction of each eye of the viewer;
d) eye region illumination information for each eye of the viewer; and
e) a position of each eye of the viewer relative to the 3D-enabled digital display;
receiving a visual blurring function for each eye of the viewer;
determining a count of projections and a three-dimensional distribution of the projections for each eye of the viewer based on the eye tracking information; and
determining a spatial blurring attribute for the number of projections for each eye of the viewer based at least in part on the received visual blurring function of the viewer.
