To do this, they integrated a Tobii 1750 desktop eye tracker with Quake 2, Neverwinter Nights, and a flash adaptation of Missile Command called Lunar Command. A study was performed that indicates the use of direct feedback from eye movements can drastically increase the feeling of immersion (pdf) in the virtual world."
