- (disclaimer: I don't know how the "Dreamlight" works).
- Rather than sense the physical movement, how about a simple EMG monitor
- that picks up muscle activity around the eye socket? This should suffice as
- an REM detector.
- Another idea I had based on readings in dream physiology would be to
- monitor the standard deviation of the respiratory rate. This would be
- cheaper. Don't how about how the accuracy would compare.
