Well, they're not just tracking eyes: they are using eye position, focus, and gestures to control a user interface which is a bit different.
The moment the stuff you want to track (eyes) also makes the enviroment change (ui) stuff can get tricky.
Eye blinking also changes the way we perceive stuff. If we use our eyes to control a UI, blink events are also special because they usually happen when we have processed enough information from a scene (Walter Murch book: In the blink of an eye tells something about this from a filmmaker perspective).
So... not as easy as it looks at first sight (no joke intended ;-).
- chewxy 10y agoWhen I wrote EyeMap, it turned out humans blinked a lot more than I had anticipated. It wasn't much later until EyeMap had been shuttered before I read that same book. What I did was basically ignore the 5 or so frames where the eye was blinking because EyeMap's main purpose wasn't to be a UI - the button pressing bits are only for calibration purposes.
