“Collision Watch is an application that runs in the background of Android mobile devices, constantly monitoring the device’s GPS, accelerometer, and movement patterns. When the system detects a significant number of indicators that suggest the owner has been in a vehicle crash (a sharp shift in motion while driving, perhaps), the device initiates a series of notifications to primary contacts and emergency services. Having collected data on the conditions leading up to the incident, the service delivers information to emergency responders that helps establish context and potential needs.”
