lullaby sleep tracking systemSleep tracking is an innovative concept and now days there are different types of sleep tracking devices available. Gadgets shaped like headsets, bracelets, and thumb drives (like the ZeoBasis, or Fitbit) even under-mattress sensor pads that will track a whole constellation of sleep indicators—body temperature, movement, electrical activity in your brain are at offer in the open markets.

Recently an advancement has been achieved by the prototype tracker built at the University of Washington which goes one step further.

It doesn’t just show when you weren’t resting well, it helps you understand why your Zs were thrown off. It tracks your sleeping environment, picking up things like room temperature, ambient light intensity, background noise—and matches those up with biological sleep signs mapped by the wrist-worn Fitbit. An IR camera takes a photograph of the sleeping subjects every 15 seconds, adding a staggered video log to sleep data being collected. Over a morning cup of coffee, on a tablet app, a user can flick through data gathered the previous night.

The sleep tracker was tested with four randomly recruited people for about two weeks, setting it up on bedside tables in their rooms. The designers of the device thought hard about privacy concerns when they designed the setup. The testers could review and delete sections of footage that they didn’t want seen, or private conversations they didn’t want heard. They could also turn the device off if they didn’t want to be recorded at any time.

More than a dozen samples collected were analysed and revealed different findings . One user discovered the frequency of his snoring habit and another saw how often she turned over in her sleep. In a third instance, one user was able to pin down the moments during his sleep cycle when he started sleepwalking.

While other devises including the Fitbit or Zeo focus on gathering biological data, the Lullaby’s comprehensive tracking ability makes it more comfortable as this kind of technology gets ever-more advanced.
