At this month’s 2012 International CES technology conference in Las Vegas, NV, EyeTech Digital Systems (Mesa, AZ, USA) took the wraps off two new eye tracking systems that are both based around a proprietary USB camera.
The new VT2 Mini is the smallest eye tracker developed by EyeTech. The portable system magnetically attaches to any laptop or desktop computer screen and is designed for short distance tracking.
The VT2 XL, on the other hand, is larger in size and designed for long-distance tracking -- up to 10 ft away -- and as such is more suited for TVs and larger computer monitors.
EyeTech Digital Systems VT eye trackers operate at speeds upwards of 100 Hz, are accurate within +/-0.5 degrees, and can tolerate head movement.
