I am looking at using the accelerometer as an input channel for controlling a game on the Blackberry. However, I only want to respond to it when the user makes a violent motion to the left or the right.
So my question is: what is the range of input to expect from a user holding the device in their hands and what threshold should I set to be sure I don’t respond to normal movement during play?
I did accordingly to Marc’s answer and I wrote a test that gave me the range of input. Each x, y, and z axis can have a value of -1048 to 1048 (as fas as I can tell). There is additional information on how to use the AcceleratorSensor to read these values and what they mean in the 4.7 API documentation.
After further testing on the device I figure that a variation of +/- 1000 in any direction within 50ms was enough to separate normal movement from a shake.
