Lightweight wearable eye tracking system
*Developed with the support of PUPIL LABS in Germany.
ViewTracker3 is a new eye tracking measurement system with a light-weight headset that adopted USB3.0 for its interface.
Three small digital cameras are mounted, and the data of the field of vision and the movement of pupils of both eyes are obtained.
The gaze data will be measured in real time.
Captured images can be transported and saved to Windows computers by USB 3.0 cable.
Small pupil cameras allow the eye tracking measurement for the downward gaze, and the posture and the position of the cameras can be flexible.
For a user wearing glasses, this headset can be wearable under their own glasses and corrective lenses are not necessary.
