Sleep Tracking Device Videos

---

This video demonstrates a full use case cycle, from setting the device up for a night's sleep, up until the 'wake-up stage'.

• Alarm time is inputted
• A 'wake window' is inputted - a duration of time up until the alarm time that the user is happy to be woken up during. The device will wake up the user at the optimal point during this part of the user's sleep cycle. (The 'wake window' is hard coded to 40 secs for the purpose of the demo.)
• Sensitivity (for the microphone) is inputted
• The program is then started: the algorithm executes as normal, interpreting background noise as movement, and eventually performing the 'wake-up stage'.
• Once the device decides to wake the user up, a light gradually brightens, imitating a sunrise.
• An alarm is eventually played to wake up the user, if the light did not succeed.
• Sleep data is then processed and stored on the device.

This video demonstrates sending the 'sleep data' from video 1 to the program that I made for the device.

• Device is set up to start 'listening' for a connection
• The program connects to the device via the 'Retrieve' button on the GUI. The connection is set up over my WiFi network, as the device uses a Raspberry Pi. 
• Sleep records are then automatically sent to the program, from the device.
• The sleep data is then processed by the program, so that the user's movements throughout the night can be displayed graphically.
• The 'sleep data' from video 1 is then displayed (i.e. the background noise picked up, interpreted as movements).
• The connection with the device is terminated.
