  • San Francisco, told Mashable. “Even without that knowledge, however, I’ve been impressed with the application. It’s easy to use and appears to give me relatively clean feedback about my own sleep patterns…I think this app and others similar to it give people awareness of aspects of their lives that would be otherwise invisible to them.”

    " this algorithm determines a subject's sleep state by examining the ActiGraph activity over an 11 minute sliding window. For any given window, a "Sleep Score" (whether the person is asleep or not) can be determined by applying this formula. After selecting a sleep time (Time In Bed (TIB) and Time Out of Bed (TOB)) each minute of sleep data is analyzed this way"

  • Actigraphy is a non-invasive method of monitoring human rest/activity cycles.
  • determining sleep patterns and circadian rhythms
  • Actigraphs have a number of different ways of accumulating the values from the accelerometer in memory. ZCM (zero crossing mode) counts the number of times the accelerometer waveform crosses 0 for each time period. PIM (proportional integral mode) measures the area under the curve, and adds that size for each time period
  • ...3 more annotations...
  • TAT (time above threshold) uses a certain threshold, and measures the length of time that the wave is above a certain threshold. Literature shows that PIM provides most accurate measurements for both sleep and activity, though the difference with ZCM is marginal.
  • Fastest sample rate: 1-minute intervals provide adequate detail to measure sleep,
  • Weight: the heavier the actigraph, the more disruptive its use.
