Eye tracking has always been a tough problem. Multi-camera solutions existed in order to sense the position of the eyes in 3D space but in general watching where your peepers pointed was too hard for cellphones. Now researchers at MIT and the University of Georgia have created an eye-tracking system that depends on crowdsourced data.The team created a simple app that showed a dot on the screen and then asked if it was on the left or right side.
