Abstract:
Gaze tracking functionalities provide a new way of interacting with electronic devices. As things are now, they are often limited to one specific device and require proprietary hardware and software. We propose a solution for web applications to counteract those limitations. By using the latest web technologies, we ensure platform independence. Due to the design and modularity of our solution, gaze tracking solutions become interchangeable. Web applications can easily consume gaze data provided by a generic event-based web-interface. The main contribution of this work is a universal calibration and mapping functionality. The raw data of miscellaneous gaze trackers can be processed and trans-formed, so that the gaze points are stabilized and correctly mapped onto screen coordinates. In the present paper, we describe the three-layer-architecture we use. Our work shows how to combine recent web technologies and algorithms to supply gaze tracking functionalities in a generic way.
