Using accelerometer to calculate speeds

Question

I\'ve been doing a bit of research on a problem we are trying to solve. I think this is the best approach but please add in your opinions

We are trying to calculat

Answer 1

Interesting application.

You are missing an important point. You either have to implement the so-called sensor fusion yourself or use the sensor fusion provided on the platform you are using. Both Android and iPhone have one.

The TYPE_LINEAR_ACCELERATION (Android, SensorManager) or userAcceleration (iPhone) should be sufficient for you.

As for the linked PDF, don't try integrating the acceleration, you will get very poor results. Even though that answer is about position, the velocity will already be inaccurate. I would try the GPS instead.
