I think interfering with a biological necessity that is there to maintain eye health probably isn't a good candidate for HID input. I suspect the user would end up with very dry eyes, as they subconsciously/consciously refrained from blinking, even if it were only long blinks (which I do often if my eyes feel the need).

Now I could see a wink working! Left wink, right wink. And, with a wink, you don't lose tracking during the action (just half the signal).

This is built for accessibility for people with extreme impairments. Think quadriplegic, ALS, nervous system disorders, etc.

Talk about eye health...are there any studies of long term IR exposure on the eyes? (I am assuming they are using IR sensors.)

It's unclear why an iPhone would be worse than a 60W light bulb, or the sun, both of which emit so much IR you can feel the heat with your hands.

Why not double blink? Or a flare of the nose?
