Need to read android sensors really fast

Question

Issue:-

1. I am developing a application which needs a new acceleration datum every 5 millisecond.

My Approach:-

Answer 1

As I understand it, the accelerometer is very noisy and not suitable for fast operations. See the GoogleTech talk on sensor fusion at http://www.youtube.com/watch?v=C7JQ7Rpwn2k for a more authorative explanation and what you can do about it. Short explanation: Use the gyro for high speed events and the acceleromenter to correct the drift.
