Gazetracker: software designed to facilitate eye movement analysis

The Eye-gaze Response Interface Computer Aid (ERICA) is a computer system developed at the University of Virginia that tracks eye movement. Originally developed as a means to allow individuals with disabilities to communicate, ERICA was then expanded to provide methods for experimenters to analyze eye movements. This paper describes an application called Gaze Tracker™ that facilitates the analysis of a test subject's eye movements and pupil response to visual stimuli, such as still images or dynamic software applications that the test subject interacts with (for example, Internet Explorer).
