Filtering out accelerometer noise

At one point, I thought about using the accelerometer and compass in the G1 to turn the phone into a gyromouse/Wiimote style thing. After playing around with the accelerometer and compass, I decided that they were a bit too noisy to do that easily, so I shelved it because of time constraints.

Well, googling around today, I found this article on Kalman filtering, which might help me to cut down on some of that noise.

Kalman Filtering

Maybe, if I can get that working, Wiimote-style pointing could find it’s way into RemoteDroid sometime in the future.
