Hello people,
I ran a few experiments on calculating displacement using the accelerometers only, and to no surprise the reading, and the calculated displacement never matched the actual displacement, I suspect due to noise.
I tried to remove as much noise as possible by moving the watch stationary, vertically up a wall to a height, and then back down again to the start position.
Has anyone use the filter features in the Math class with success to filter accelerometer noise?
And, it looks like the IIR filter is or can be setup similarly to a Kalman filter since it has fed forwards filters?
Has anyone used it like this, or am I better off just setting up a stand alone Kalman?
Initially I am hoping to remove the higher frequency noise, but possibly also minor hand motion in a later step
