Kalman is not a detector by itself, but filter. And what you really detect is in fact not user movement but device movement which then you *assume* equals user moves (as usually phones do not move by itself). To make sure user really moves you may need additional location information. Of course once you have location accelerometer may become useless however since GPS drains battery badly I'd combine both and use triangulated provider instead, just to know user moved in given period of time and combined with your accelerometer readings that may lead somewhre. Note that user may move but not "wave" (i.e. using car) -- Regards, Marcin -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
