I've had success using a digital band pass filter. Instead of fiddling with velocities, a band pass filter just looks at the power spectrum within a limited frequency range. I posted my code in the following thread:
http://groups.google.com/group/android-developers/browse_thread/thread/d61f7790afb3f8b6/770777368e823548?lnk=raot One problem with this particular example is that the center band of 3.6 Hz is too high. I think a center band of 1.8 Hz would work better. If I get some time, I'll try recomputing the cooefficients, but meanwhile you could also work out the math in the linked reference. The other improvement to my example code would be to detect shake on more than one axis. hth -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
