Abstract: Most common eyetrackers today use corneal reflections to follow and record a person's gaze while looking at something within an accuracy of 5 mm. This technology offers standard communications to the disabled community, brings new objective measures to supplement traditional qualitative tests of customer engagement, and enables all users to interact with and control a computer by eye movement alone. This article presents the principles, advances, and future applications of eyetracking technology. [ABSTRACT FROM AUTHOR]
