Eye Tracking for Mobile Control

Dartmouth College researchers have created EyePhone, an eye-tracking system
that enables users to operate smartphones using their eyes. Dartmouth
professor Andrew Campbell says his research team found that keeping track of
a gaze using a mobile phone is much more difficult than on a desktop computer
because both the user and the phone are moving, and the surrounding
environment is so changeable. "Existing algorithms were highly inaccurate in
mobile conditions - even if you are standing and there's a small movement in
your arm, you'd get a large amount of blurring and error," Campbell says. The
researchers developed an algorithm that learns to identify a user's eye under
different conditions. EyePhone goes through a learning phase, in which the
system is trained to identify a person's eye at varying distances and under
different lighting. A user calibrates the system by taking a picture of the
left or right eye both indoors and outdoors. Campbell says the system is 76
percent accurate in daylight while the user is standing still and 60 percent
accurate when a person is walking.
