From my experiments I would guess the Tinkerforge IMU2 Brick doesn't have linear accelerator sensors that are accurate enough for me to reliably detect movement, am I correct?
I created a simple Unity3D project to move and rotate a cube on screen. The rotation sensitivity was excellent, but the linear acceleration wasn't reliable enough to detect how much I had moved, when I had moved the brick back to its original position etc.
So can't LinearAcceleration be used for this purpose, and what can it be used for?
