"EyePhone" lets users browse through mobile phone menus at the blink of an eye.
A team at Dartmouth College has now created an eye-tracking system that lets a user operate a smart phone with eye movement.
Mobile eye tracking could be useful for all mobile phone users, says Dartmouth professor Andrew Campbell, who led the development of the new system, called EyePhone. But so far, little work has been done on eye tracking on mobile phones. This isn't surprising--keeping track of a gaze via a mobile phone is much more challenging than on a desktop computer because both the user and the phone are moving, and the surrounding environment is so changeable.
