I've heard of some folks suggesting this, but not of anyone that has actually tried.
The first thing you would likely need is a 'sensor fusion' algorithm that can use gyro/accelerometer/magnetometer values and get a good idea about XYZ values.
Realistically you'd probably be better sending the raw sensor data from the Puck to a PC, and doing the sensor fusion there - because if you know a Puck is attached to a certain joint then those restrictions could actually help with the reliability of the data since it'll give more of a clue to where the Puck actually is.

Thank you so much! I’ll let you know more if I’ll be able to succeed. Actually we would like to integrate the bangle 2 too. Is it feasible in case to provide the Puck with a small motor for vibration alerts?

The Puck does have a 'FET' output pin which provides a higher powered output, so you could attach a (small) motor between the
3V
pin and that, but the CR2032 battery doesn't provide much power. You could always add a bigger battery as well but then the whole thing starts to get quite large!
Hi guys,
I'm trying to use acc and gyro data to reconstruct a human manikin of the user, have you ever tried to do something similar or do you have any suggestion?
Thanks in advance!
