CMOS Image Sensor for High Speed and Low Latency Eye Tracking

Abstract

Eye tracking, or detecting where the user is looking at, is expected as a new type of user interfaces, with including the phenomenon of rapid eye movement, so called saccade. However, real-time tracking of saccade is difficult with the conventional image processing systems for their long processing time and latency against the speed of saccade. In this paper, we describe the design of the CMOS image sensor for eye tracking with high speed and low latency capability, as well as its evaluation results.
