DLRC Eye Tracker

The Discovery Learning Research Center provides a remote eye tracking device that may be used in the development and evaluation of digital curricula and instructional materials. The equipment is located in the Hall for Discovery Learning Research and is available to Purdue faculty, staff and graduate students engaged in STEM-related learning research. The eye tracking device, a Tobii model TX300, is capable of providing information about the location, sequence, and duration of a participant’s gaze fixations. The Tobii TX300 allows subjects to have freedom of head movement so they may interact naturally with the system as they would with any computer.

Using the DLRC Eye Tracker

Training is required for faculty, staff, and graduate students prior to use of the eye tracker. A training fee will be charged. Training is requested via an online form.
