Abstract:
We propose a novel eye-tracking technology based on a micro-scanning mirror and linear array photodetector. We find the evidence that changes of the gaze position will cause the change of the reflected light path which can be a promising eye-tracking signature. We use this feature through a functional system called Scanning Micro-Mirror based Eye-tracking Technology to realize eye-tracking.
The key feature of our eye-tracking system is low power consumption, 264mW which is more than ten times lower than other widely used tracking technologies today, without compromise precision, 0.19º, and tracking speed, 60Hz.
The thesis mainly introduces our system design, related work comparison and experimental analysis. Also, state-of-the-art eye-tracking technology and various tracking principles are introduced.
