capture an image of a face of a user viewing a display device;
identify a light source in the image;
divide the face of the user into regions;
identify light reflecting off the face of the user;
compare a light measurement from a first region to a light measurement in a second region to identify a direction of light reflecting off the face of the user;
determine a signature of the light in the image by:
positively weighting a light measurement from the light source;
