Can you do eye tracking on mobile devices? –

In addition to making existing applications of eye-tracking technology more accessible, the system could enable new computer interfaces or help detect signs of incipient neurological disease or mental illness.

We thought we should break this circle and try to make an eye tracker that works on a single mobile device, using just your front-facing camera. Khosla and his colleagues — co-first author Kyle Krafka of the University of Georgia, MIT professors of electrical engineering and computer science Wojciech Matusik and Antonio Torralba, and three others — built their eye tracker using machine learning, a technique in which computers learn to perform tasks by looking for patterns in large sets of training examples. Currently, Khosla says, their training set includes examples of gaze patterns from 1, mobile-device users.

Previously, the largest data sets used to train experimental eye-tracking systems had topped out at about 50 users.

Calling 50 people in itself is already a fairly tedious process. But we realized we could do this through crowdsourcing. In the paper, the researchers report an initial round of experiments, using training data drawn from mobile-device users.

To get a sense of how larger training sets might improve performance, the researchers trained and retrained their system using different-sized subsets of their data. Those experiments suggest that about 10, training examples should be enough to lower the margin of error to a half-centimeter, which Khosla estimates will be good enough to make the system commercially viable.

Correctly executing the tap ensures that the user has actually shifted his or her gaze to the intended location. The data set contains, on average, 1, images for each user.

Training modifies the settings of the individual processors so that a data item — in this case, a still image of a mobile-device user — fed to the bottom layer will be processed by the subsequent layers. Dark knowledge involves taking the outputs of a fully trained network, which are generally approximate solutions, and using those as well as the real solutions to train a much smaller network. With the reduced network, the eye tracker can operate at about 15 frames per second, which is fast enough to record even brief glances.

So something that will work on a device everyone has, that seems very compelling.
