SmartFall Detector

Krish Munot

This is the design document for AngelHack:

Our application tackles the problem of an unattended aging user being unable to contact help during an immediate fall or severe injury.

• Our design aims at contacting an emergency member under two conditions:
  
  1. If the user is unable to verify their condition after eight (8) minutes upon an immediate fall
     
  2. If the phone is left unintended for a user-set number of hours

Fall Detection

• Accelerometer Detects Fall: Prompts "Trigger Message"
• 180 Seconds (Inactivity): Phone vibration, audio alarm, 'flash' screen
• 300 Seconds (Inactivity): Increase all alerts
• 480 Seconds (Inactivity): Send picture, audio, and location data to contacts
  • Emergency contacts alerted

Immobilized Detection

• If mobile phone detects no activity for a user-defined number of hour(s)
• 180 Seconds (Inactivity): Phone vibration, audio alarm, 'flash' screen
• 300 Seconds (Inactivity): Increase all alerts
• 480 Seconds (Inactivity): Send picture, audio, and location data to contacts
  • Emergency contacts alerted
