Development of Corneal Reflection-based Gaze Tracking System for Public Use

In this paper, we describe a corneal reflection-based gaze tracking system for public use. There are two problems to be solved when gaze tracking technologies are employed as the interaction mechanism for public display. One is to realize a personal calibration-free system. The other is the extension of the tracking range. We developed a personal calibration-free gaze tracking system at the Maritime Museum of Kobe University by using two calibrated cameras and multiple light sources. Furthermore, we are developing a system that changes lighted LEDs dynamically to estimate the gaze in a wide range.
