Eye trackers add substantial power to your lab set-up. They produce gaze video and large quantities of rich data, all related to attention and emotion. Take advantage of our experience and knowledge: as we often integrate eye trackers into lab set-ups. We can help you find the eye tracker that works best for you.

• See what your test participant is looking at.
• Get rich, quantitative and reliable data for attention, mental load, and arousal.
• Combine eye tracking videos and other sources like FaceReader™ or data acquisition systems with The Observer^® XT.

Head mounted eye tracker
A head mounted eye tracker consists of a lightweight cap with a built-in eye tracker and video camera. It allows your test participant to move and look around freely, while you are getting a complete movie of your test participant’s view with a gaze point overlay.
In The Observer XT you can easily code the video and data for blinks, fixations, pupil dilation and gaze position. These parameters tell you everything about mental load, attention, arousal, and eye position of your test participant. This makes the head mounted eye tracker very useful, not only in Human-Factors research in the aviation and automotive industry, but also in military training, behavior studies in simulated environments, and consumer research.

Computer-monitor eye tracker
We also offer computer-monitor eye trackers that track the test participants gaze on a computer screen. They are contact free, and built into or attached to computer- monitors. This makes them very suitable for Human-Computer Interaction research, usability testing, and market research. Some computer-monitor eye trackers even allow you to see in real time what your test participant is looking at. They all make screen captures with a gaze overlay that are suitable for video analysis in The Observer XT. Moreover, you can easily import the test participant’s views as behavioral data, and integrate this information with manually recorded behavior.

Desktop eye tracker
If you are interested in your test participant’s response to physical objects such as posters and brochures, you can use our contact free desktop eye tracker. It provides you with data such as area of interest views, pupil dilation, blinks, and gaze position. The gaze path can also be overlaid on a picture. Unlike our other eye trackers, the desktop eye tracker does not produce a video.

Modular system
Are you planning to apply both head mounted and contact free eye tracking? We offer you a modular system which consists of a base unit for acquisition and analysis, and exchangeable tracking devices. This will greatly reduce the cost of your total set-up. The Observer XT is suitable for video analysis, for recording behavioral context, and for joint analysis of eye movements and behavior.
