Ever wonder if you're getting enough rest, or if you're waking up during prime deep sleep? Dream Recorder, which is being marketed as the "first software dream catcher," monitors your sleep states by detecting your motions with an enhanced night vision mode for iSight cameras.
Dream Recorder wakes you up at the best moment of your morning sleep cycle, and provides dream feed-back and voice recording capabilities. Apparently, body motions are related to the sleep phases. They occur before and after dreams and are almost absent during deep sleep phases. You awaken for very short instants during the night, without even noticing. Dream recorder uses this motion profile to reconstruct the sleep cycles.
