I think a combination of this and controlling an external light source could
manage to wake me up. No matter how loud the sound is, I would just
continue to sleep... ignoring the alarm. I hope this sleep pattern detection
is possible. If not, a mechanical lift under the top of the bed would help
(lifting the bed up to 80 deg so you get on your feat), but I can't afford it.

I hope there is somebody that can write an app for sleep state detection:)
