According to the description on page 18/115 of the "LSM6DS3TR-C.pdf", the x, y, z axis is following the principle of right-hand rule.
However, I just used
to get the corresponding acceleration values along the x,y,z axis to test 6 static poses of puck.js, i.e., +x, -x, +y, -y, +z, -z axis along with gravity direction. I got the coordinate system illustrated in the attached figure. This is not followed the right-hand rule. Is there something I missed?
