I hadn't seen that, it answers my exact question. :S Thanks though!

comment Calculating pitch and roll with accelerations greater than +/- 1g
Well, you'll have to make some assumptions. You could assume that gravity is in the same direction as the current acceleration. You could assume that the device is level. You could assume any number of things. You're simply trying to calculate too many unknowns from your known variables. Your problem is underspecified.

You can't determine whether an object is stationary or not using only an accelerometer, so you have to either assume it is or assume it isn't.

comment Calculating pitch and roll with accelerations greater than +/- 1g
As I said on Stack Overflow, there's no way to tell how strongly you're being influenced by gravity, and in what direction. The only data you have is acceleration relative to the device orientation, which isn't enough to determine anything related to gravity. Unless you can disprove General Relativity.

The problem is, you will have no idea which direction g is in, and so you'll have to guess (and probably guess wrong).

@CURIE What are you asking? I don't understand your comment.
