Here's what I mean by a baseline value: I'm using SensorManager.getOrientation() to determine the device's orientation. I am only concerned with the difference in orientation relative to a static orientation (which I'm referring to as the baseline value) at any given time. The baseline value could be hard-coded, but I'd like to have more flexibility and set this value based on the orientation of the device when the application is started.
The problem I'm facing isn't noise per se; the initial values I get from the sensor are consistently inaccurate, so I'm not sure how to obtain a baseline orientation.
