The Sleep Sensei

A device to help users fall asleep using calming breathing training.

Features

  • Creates a pattern of light that you match your breathing to
  • Breathing rate is decreased during coaching session, so this helps ease you into sleep faster
  • The maximum brightness can be adjusted on-the-fly
  • 4 built-in profiles
  • The initial breath length, final breath length, and session duration are adjustable for all 4 profiles
  • Profile modifications are saved to the device's non-volatile memory
  • One-button/knob operation

How to Use

  • Set up the Sleep Sensei on a night stand or table next to your bed.
  • Turn on the sleep coach and adjust its angle to either shine in your eyes or on a wall or ceiling.
  • Chose a profile and start a sleep coaching session
  • Follow the pattern of light with your breathing (brighter = inhale, dimmer = exhale)
  • Fall asleep faster!

Kickstarter

The Sleep Sensei is on Kickstarter!

Study

I have been conducting a study to collect data on the Sleep Coach to see if it actually helps users fall asleep.

So far I have had great success with the Sleep Sensei. I'm always looking for more study participants!
