Battery-free eye-tracking glasses developed at Dartmouth College could create an even more realistic experience for augmented reality enthusiasts. The new technology improves player controls for gaming and allows for more accurate image displays.
High power consumption and cost have kept eye trackers out of current augmented reality systems. By using near-infrared lights and photodiodes, Dartmouth’s DartNets Lab has created an energy-efficient, wearable system that tracks rapid eye movements and allows hands-free input of system commands.
The glasses, which can also h...
