Design and implementation of gaze tracking headgear for Nvidia 3D Vision®

The usage of Nvidia 3D Vision^® is increasing rapidly, ranging from gaming to research purposes. However, researchers in human computer interaction and virtual reality are constrained by hardware configuration since current commercial gaze tracking systems are not specifically designed to be used with Nvidia 3D Vision^®. In this paper, we present a novel prototype of gaze tracking headgear which can be used appropriately with Nvidia 3D Vision^®. We explain design consideration and detail implementation of our gaze tracking headgear. We also evaluate our gaze tracking system by measuring gaze accuracy on stereoscopic display. Experimental result shows that the average gaze estimation error is less than one degree visual angle.
