Sleep/Wake/Non-Wear Detetction (NonWearSleepWake):
The algorithm for sleep/wake detection uses acceleration data. It also can distinguish sleep from NonWearTime. The parameter can be calculated for an adjustable output interval. Internally the calculation occurs based on 30 s intervals.
The following table displays the relevant coding:
Lights out detection (LightsOut)
Using the sleep/wake detection in conjunction with the illumination allows the detection of the intention to go to sleep. This parameter displays when the participant turns the lights off to retire for the day in an adjustable output interval. For the calculation of this parameter, the ambient light signal of the LightMove 3 or LightMove 4 Sensor is required.
