Meet the Eye Cam

Columbia University researchers have devised a “corneal imaging system” that captures and analyzes images reflected from the cornea of the eye.
It uses a high-resolution digital camera to photograph the eye and software to calculate the viewer’s “gaze direction” to identify what they are actually looking at in a scene.
This corneal reflection shows that the person is facing two people but only looking at the one on the right
Possible uses include security, studies of human reactions, responsive computer interfaces (eye gaze replacing the mouse), and compositing for digital moviemaking.
It’s also possible to play back a digitally recorded scene and view what you missed if you had focused your vision in a different direction.
