Accelerometer vs. Gravity and LinearAcceleration

omri

Hi,

What is the difference between the accelerometer and the gravity/linearAcceleration data?

Should it not be the same thing but for different axes?

The same question goes for gyroscope data and Euler angles: the Euler angles are just the measure of the integral gyroscope change in time?

Am I missing something here?

Thanks!

Accelerometer data is composed of both gravity and linear acceleration.

Yes but gyroscopes are noisy. Using only gyroscope data to approximate orientation will result in noticeable errors.
