  • Can be used with screens up to 32"
  • Modular design (monitor, projection screen, real world ...)

This unique new technology solves eye tracking‘s tolerance-to-head-motion challenge once and for all. The EyeFollower accommodates all natural head motions e.g. during computer operation. The user can sit back, sit up, slouch down, move side to side, reach over to the mouse, operate the keyboard, and move close to the screen to examine a display at close range.

Unmatched head motion volume - unlimited freedom

Unlike other eye tracking device, the EyeFollower uses 2 additional cameras to track the movements of your head. If you turn it or move it away, the device detects it and follows your movements precisely. Your pupils stay in focus.

Automatic eye acquisition

The EyeFollower automatically locates the eyes when the user enters the work-space, and it rapidly re-acquires the eyes when he returns his attention to the screen after turning his head away.

Enhanced focusing technology

4 Camera Tracking

The system uses special cameras to track the head position and adjust the eye tracking cameras to the subject‘s eyes.

High accuracy

The EyeFollower achieves its highly accurate < 0.4-degree gaze point tracking accuracy throughout the whole operational head range. Even with high computer processing loads, the system samples data at a constant 120 Hz.

Binocular eye tracking

The EyeFollower tracks both eyes over the full range of head motion to enhance accuracy.

Easy calibration

The hands-free calibration is fast, easy to operate, and long-lasting. The calibration can be saved and reused when working with the same subject again.


The EyeFollower may be used with a wide variety of computer monitors, with a projection screen, with stereoscopic displays, or in a real-world, 3-dimensional setting with no monitor at all. 3-dimensional gazepoints are available for real or simulated 3D environments.
