To save my hands from CTS (Capal Tunnel Syndrome), I want to have a mouse that uses an accelerometer, connected to any limb in the body, to replace the conventional mouse that you move with your hand.
In other words, I want a mouse that I can move with movements of my body that do not require me to move my hands away from my keyboard.
Did anyone make such a project? Is anyone selling such things? I could try to build this myself, but if someone already built one before, I prefer to rely on existing knowledge.
EDIT: What would be really nice is a link to a video of such a project that is built well enough to be used every day, not just a proof-of-concept.
