Watch Dog

Watch Dog is a safety app created during HACKISU along with 3 other members. It's designed to detect if its user is in distress or under attack. The inspiration behind this app was a recent fatal attack on a fellow ISU student while they were alone. Our goal was to create an app which could sense signs of distress, and alert emergency contacts, record video/audio evidence, or sound an alarm to scare off an attacker.

My part in this project was sensing signs of distress. I did this by developing an algorithm to use a phone's accelerometer to detect if the phone is falling, as well as using a seperate library to read audio inputs to see if the user said phrases like "Help me".
