What is eye tracking?
Eye tracking is a non-invasive method used to measure where people look while performing different tasks. A small camera records eye movements and pupil size while you view information on a computer screen.
Before your visit
Please arrive a few minutes before your scheduled session.
If you normally wear contact lenses, you may wear them during the experiment.
If you wear glasses, you can usually participate, although some types of glasses may make eye tracking more difficult. If you have both glasses and contact lenses, we recommend wearing contact lenses if possible.
If you wear colored or cosmetic contact lenses, please let the researcher know before the session, as they may affect the quality of the recordings.
What happens during the experiment?
A researcher will explain the study and answer any questions you may have.
You will be seated comfortably in front of a computer monitor. Depending on the study, you may be asked to place your chin on a chin rest to help keep your head still during recording.
Before the experiment begins, the eye tracker will be calibrated. This usually involves looking at a series of dots on the screen.
During the experiment, a small camera located below the monitor will record your eye movements and pupil size while you complete the experimental tasks.
The eye tracker does not shine anything into the eye and does not touch your eyes.
After the experiment
The researcher will explain the purpose of the study and answer any remaining questions you may have.
