Enabling non-intrusive gaze interactions in existing computer games

Sammanfattning: Eye tracking have been around for many years now, but until recently the technology have been expensive and the performance too low for the mass market to pay any attention. But times are changing and the cost of eye trackers is going down and performance is getting better. Eye tracking will soon start appearing in more and more homes around the planet. With the advent of eye trackers in people‟s homes, it is time to start thinking about what users would want to use eye tracking for. A popular field that comes to mind is gaming. Adding eye tracking to games could change gaming significantly. Experiences could be enhanced and new genres created. A deep integration with the games would allow eye tracking to blend smoothly with the game; creating a natural and immersive experience. However, it will take a while for the game developers to make this come true. In the meantime something else is needed to fill the gap between now, when no game had eye tracking support, and the future when all games will have a deeply integrated eye tracking interaction. The product we came up with is a tool for non-intrusively integrating eye tracking into existing games. This means that the tool is able to add eye tracking support without the need to modify the game in any way.
