I looked like a comatose Robocop.
Both WakeMate and FitBit, worn on your wrist during sleep, use motion-sensing technology
(accelerometry) similar to what's found in a Nintendo Wii controller. The data are interpreted
using actigraphy algorithms, which are used to determine whether someone is awake or in one
of the various stages of sleep. WakeMate features an alarm clock that can be set to wake you
during speci c "arousal points" in REM sleep (ostensibly to minimize grogginess) up to 30
minutes before a chosen wake time.
The Zeo, in contrast, uses a headband that measures electrical patterns generated in the brain.
It also has an alarm clock intended to wake you during periods of most elevated brain activity
to minimize grogginess.
The first attempts to track and fix things were not encouraging.
