There are a lot of tricks people have come up with to minimize this noise using things like Weiner and Kalman filters. Third as you may have noticed the accelerometer reading is not constant. I don't simply mean that the values are.. But it means again that in the short run this adds noise to our system. If you use a good perdictive filter like a Kalman filter then it should be able to account for this but weaker filters may need some help. One way of doing this is to average..
