Understand that the accelerometer shows force in 3 directions. When the phone isn't moving, it will have 9.8m/s2 (gravity) reading on it. You can use that to figure out exactly where the phone is pointed. You can get 3 vectors to show the angle of X,Y and Z relative to gravity if you use arctan(r0,r1) arctan(r1,r2) arctan(r0,r2) where r0, r1 and r2 are the first 3 values of accelerometer readings. This is all the information I can give you because after that, it's all clever programming to make good use of these numbers and that is application- specific.
