Description of Operation
DynoStorm uses the accelerometers built-in to your Blackberry Storm to measure G-forces acting on the phone. Just as you feel pushed-back in your seat under quick acceleration, the device is able to “feel” the acceleration of the car. The measured G-forces are fed into a vehicle dynamics model, which is used to determine the motion of the vehicle, taking into account the action of the suspension and other factors. This then allows DynoStorm to compute the rate of acceleration, and from this a current speed and distance travelled.
