Why is nobody making a mouse with a motion sensor!? All the mice Clem could find online use optical sensors, so he asks the question: why not use an IMU (inertial measurement unit) as a way to track the movement of a mouse in space? Armed with a PCB he made in KiCad and great ambitions, he soon encounters the truth: it's really hard! The math is challenging, and the outcome would barely be usable, but Clem also learns that building a 3D air mouse this way would be quite easy.
