Anyone tried something like the
Tobii Eyex or the
Steelseries Sentry (I believe Tobii collaborated with Steelseries on it) or even just a webcam with appropriate software as a pointing device? The basic idea seems really interesting to me, I imagine you could even use eye gestures for actions.
I'm worried about the accuracy, at least with these cheaper alternatives. It can't be anywhere close to the level a modern mouse is can it? Also no idea about what kind of tools currently exist for translating the input to the cursor movements.
