Two existing alarms that also work on this premise:
- One has a light that brightens over the course of an hour to simulate the sun rising. Supposedly the natural progression of brightness in your room will help set your internal clock (or something like that) [1]
- Some sort of monitor that you wear that monitors what phase of sleep you're in. You set the alarm to a certain time, and the alarm picks the right time to wake you up, depending on your sleep cycle. [2]
