filtering in an even simpler way which is by using ramping ramp speed play with this value until satisfied const float kFilteringFactor 0.1f last result storage keep definition outside of this function eg. in wrapping object float accel 3 acceleration.x .y.. from the sensor result.x .y .z is the filtered result high pass filter to eliminate gravity accel 0 acceleration.x kFilteringFactor accel 0 1.0f kFilteringFactor accel 1 acceleration.y kFilteringFactor accel 1 1.0f kFilteringFactor accel 2 acceleration.z.. .z is the filtered result high pass filter to eliminate gravity accel 0 acceleration.x kFilteringFactor accel 0 1.0f kFilteringFactor accel 1 acceleration.y kFilteringFactor accel 1 1.0f kFilteringFactor accel 2 acceleration.z kFilteringFactor accel 2 1.0f..
