Is it possible to combine an Accelerometer and Digital Compass to get a fine Gyroscope?

Question

I want to make an app that need to use Gyroscope Sensor

However, due to cheap android phone didn't provide this sensor but it still have accelerometer and digital-compass in itself.

As far as I know.. Since, accelerometer can detect 3 axis of our phone. When compare to Gyroscope, only the thing they lack is they can't detect if user rotate their phone without changing their pose. That's why I need to use digital compass to get the north direction to solve this problem.

So, I would like to know is it possible to just use only these 2 sensors to make a gyroscope sensor work-like? Anyone ever try? Is it actually work?

Thanks

Answer 1

It is not clear why your app needs gyroscopes. I assume that you want to track the orientation of the phone.

You can track the phone orientation reasonably well with the accelerometer, compass and a low-pass filter. It lags a bit but it works, I have impleneted that for the Shimmer platform. See also my answer here with the link to a demonstration video.
