DLRC Eye Tracker

The Discovery Learning Research Center offers a non-intrusive Tobii Technology TX300 eye tracking device that is available to researchers through a recharge center. The eye tracking device provides information about the location, sequence, and duration of a participant’s gaze fixations on stimuli displayed on a computer monitor screen. The Tobii TX300 is capable of measuring gaze location without contact with the participant allowing subjects freedom of head movement. The TX300 is equipped with Tobii Studio 3.2 software which accommodates various multimedia stimuli including images, text, videos, and web pages. The software package provides comprehensive data visualization, statistical metric calculation, and data export features.
