Interesting. Could an external stimulus trigger a subconscious blink?
you could set something up where a water gun squirts you on a random interval between 2-5 minutes. heh i think i would kill someone if they did that to me.
The web app can trigger a notification if your blinks / minute drop too low. Only challenge is modern browsers throttle websites that aren't visible, so the blink counting gets messed up.
E.g. let your app give a signal (e.g. beep or buzz) every 30 seconds if you don't blink. Then train yourself to blink if you hear the signal.
Edit: Yes, it can be done: https://en.wikipedia.org/wiki/Eyeblink_conditioning
