Hi!
First of all, congratulations for your project.
I'm developing a movement quantification system, with a 3-axis gyro and a 3-axis accelerometer.
In my first approach i'm only using the 3-axis acc to get the rotation using for that purpose the atan2 function and the acceleration vectors.
Two questions, did you test this approach? And a newbie one, how did you used the quaternions with the gyroscopes?
thanks in advance for your answer.
Regards
