Development of a mobile tablet PC with gaze-tracking function

Abstract

In the near future, interfaces for personal information devices with large touch screens that are capable of processing different types of information in a more intuitive manner will become indispensable. In this study, we developed "MobiGaze.PC," a system that can achieve stable gaze tracking on a mobile tablet PC. Users can interactively acquire information using both the touch screen and gaze tracking on a mobile device. First, we created the hardware setup using a tablet PC, cameras, and other apparatus. Next, we developed a method of detecting the eye area using a Purkinje image, and the position of the center of the pupil and the Purkinje image in low resolution. We then performed experiments to evaluate the accuracy of these methods. Finally, we developed a number of multimodal applications of the proposed system. © 2013 Springer-Verlag Berlin Heidelberg.
