Preliminary Evaluation of High Speed and Low Latency Eye Tracker using Custom CMOS Image Sensor

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 a high speed and low latency eye tracking camera using a custom designed CMOS image sensor, as well as its evaluation results and design of the improved CMOS image sensor.
