Gaze tracking in multi-display environment

This paper presents the basic ideas of eye and gaze tracking in multiple-display environment. The algorithm for display detection and identification is described as well as the rules for gaze interaction in multi display environment. The core of the method is to use special LED markers and eye and scene tracking glasses. Scene tracking camera registers markers position which is then represented as a cloud of points. Analyzing the mutual positions of detected points the algorithm estimates screen/displays position. Display number is assigned based on special information marker. Described project shows the possibility of hands free interaction in MDE. It also presents how to register visual attention when information is dispersed on several screens.
