Hi!
To investigate the impact of gaze-based game interaction on the phenomenon called presence we, the glab (games lab) of the University of Applied Sciences Upper Austria, created 2 game prototypes with two Tobii eye-trackers (Tobii EyeX and REX).
You can see the results in this short video:

Prototype 1: Fractile, 3D Game; Game Engine: Unity; Tracker: Tobii EyeX
Prototype 2: Limus and the Eye of the Beholder; 2D Game; Game Engine Construct 2; Tracker: Tobii REX
The prototypes were evaluated during the GameStage Expo 2014 in Linz – things worked really well – thanks Tobii! Results: coming soon!
All the best,
Michael
