Eye trackers

Eye trackers add substantial power to your lab set-up. They produce gaze path 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 as well as portable set-ups, we can help you find the eye tracker that works best for you. Noldus will assist you in the process from start to finish, including lab installation, training your team and setting up experiments, and creating custom scenarios.


  • See what your test participant is looking at, and is not looking at, or missing during interaction.
  • 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.
  • Benefit from a completely integrated system.
You can sync multiple data streams, including your eye-tracking data, with Noldus' tools.


A head mounted eye- and gaze tracker consists of lightweight glasses with a built-in eye tracker and video camera. It allows your test participant to move and look around freely, while you, the researcher, get to see a complete video of your test participant’s view with gaze point overlay. Due to their sleek and subtle design, eye-tracking glasses are ideal for everyday activities like walking around in a shopping mall.

In The Observer XT you can easily mark interesting events and import eye tracking data such as number of blinks, fixations, pupil dilation, and gaze position. These parameters supply a wealth of information related to mental load, attention, arousal, and eye position of your test participant, making 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 and desktop eye tracker

We also offer computer-monitor eye trackers that monitor the test participant’s gaze on a computer screen. Built into or attached to computer monitors, these hands-free devices are widely used for Human-Computer Interaction research, usability testing, psycholinguistics, medical simulation, and market research. While all computer-monitor eye trackers can do screen capture and overlay the gaze track, some trackers even allow you to see this data in real time. After importing the videos to The Observer XT, you can analyze the test participant’s views as behavioral data, and synchronize this information with manually recorded behavior, physiological data, and facial expressions.

Remote and flexible eye tracking

If you are interested in your test participant’s response to marketing stimuli like posters and product displays, you can use a remote, contact-free eye tracker. This setup provides you with data such as area of interest, pupil dilation, number of blinks, and gaze position. The gaze path can also be overlaid on a picture.

Integrated system

The Observer XT is a multi-functional tool: Ideal for video analysis, recording behavioral context, and synchronization of eye movements and behavior. Use the Observer XT to combine all your videos with data gathered using other software or hardware such as FaceReader, uASQ, or physiological equipment. No manual synchronization required – a Noldus setup allows you to com¬plete your studies accurately and efficiently without needing to worry about integration. DriveLab is an example of a completely integrated system combining video recording, eye tracking, and simulator data.
