How does eye tracking work?

Light from infrared cameras is directed toward the participant’s pupils, causing reflections in both the pupil and the cornea. These reflections, otherwise known as pupil center corneal reflections (PCCR), can provide information about the movement and direction of the eyes.

Academic researchers use information about eye movements and fixations to assess attentional processes, compare group behavior, measure stimuli-induced visual responses, and more.

Leading consumer brands use eye tracking to better understand customer experience and product performance by measuring visual attention to key messages in product advertisements, placement and branding, package design, and more.

A Complete Eye Tracking System: Hardware & Software

For high accuracy and precision eye tracking research that generates meaningful insights, you’ll need to think about which type of eye tracker is suited to your studies and how you will analyze the collected data with software. How these systems work together will dictate the quality of your findings.

Your eye tracking system setup may be screen based for stationary studies, glasses for ambulatory, or VR eye tracking in virtual environments. iMotions software is compatible with all three.

What is Gaze Mapping?

If you want to measure visual attention to specific elements in the real world across participants with eye tracking, iMotions provides a way for dynamic visual content to be represented by a static image – this is called gaze mapping.

• iMotions computer-vision algorithm identifies representations of the reference image (left) in the recording (right).
• The software corrects for differences in distance and angle across participants and maps the gaze onto the reference image.
