Self-made mobile gaze tracking for group studies

Abstract

Mobile gaze tracking does not need to be expensive. We have a self-made mobile gaze tracking system, consisting of glasses-like frame and a software which computes the gaze point. As the total cost of the equipment is less than thousand euros, we have prepared five devices which we use in group studies, to simultaneously estimate multiple students' gaze in classroom. The inexpensive mobile gaze tracking technology opens new possibilities for studying the attentional processes on a group level.
