Recognizing Gaze Direction with Machine Learning

In Technology Review:

Virtual Eyes Train Deep Learning Algorithm to Recognize Gaze Direction

Gaze estimation is a classic problem of machine vision, which can now be solved by one computer training another.

Eye contact is one of the most powerful forms of nonverbal communication. If avatars and robots are ever to exploit it, computer scientists will need to better monitor, understand, and reproduce this behavior.

But eye tracking is easier said than done. Perhaps the most promising approach is to train a machine-learning algorithm to recognize gaze direction by studying a large database of images of eyes in which the gaze direction is already known.  ... "
