Sleeptracker wake-up device monitors your sleep to make waking up easier

March 7, 2005 Sleeptracker looks like a wristwatch but it monitors the wearer's sleep patterns to detect the best possible wake-up times. Sleeptracker's alarm then goes off at the optimum moment during a pre-set, customised window of time, so that the wearer wakes up alert and energized. According to Sleeptracker's creator, Innovative Sleep Solutions, during a typical night, most people go through continuous cycles of sleep stages, progressing from deep sleep to almost-awake moments and back again. If their standard alarm happens to ring at an almost-awake moment, the person wakes feeling rested and refreshed. But as the cyclic pattern is only at an optimal state for waking a small percentage of the time, a standard alarm usually goes off during deeper sleep, so that those people wake up tired and groggy.
