Haven't tried anything like this recently so I was curious how accurate it was.

I am impressed but there is some delay and lagging behind when moving the phone.

I'm using a low pass filter on the raw sensor data to minimize any jittery input.
The code I'm using is as follows:
alpha = 0.1;
output = previous_output + alpha * (new_input-previous_output);
Complementary filters works well enough and is very simple to implement even if you're a noob (e.g., high pass on accelerometer and low pass on gyro).

Worked pretty well!
