In the event of a vehicular accident, there are many scenarios in which the occupants become incapacitated and unable to call for assistance. There exist systems, e.g., OnStar, that currently provide accident detection and roadside assistance services. However, the cost of these proprietary systems and their availability for all vehicular models limit their use.
Project FrogStar provides for accident detection and emergency responder notification in an inexpensive and highly available system. The primary FrogStar system components include a smartphone, a single-board computer, and Texas Instruments SensorTags placed inconspicuously around a vehicle. The single-board computer monitors the TI SensorTags, via Bluetooth low energy, obtaining accelerometer and gyroscope data needed to detect accidents. The smartphone provides the means for emergency notification and, when utilizing its own sensors, allows for redundancy in accident detection.
