The Bit

A tongue IO device

The goal of this project is to create a new input device that allows the user to control a mouse with a small sensor placed on the roof of the mouth. I imagine this HCI will benefit those who have poor/nonexistent use of their fingers or those who need to use their hands elsewhere at the same time they control a mouse.

I have assembled a functional prototype that includes a bite force sensor to activate tracking (with light pressure) and to detect clicks (firm pressure). All design details will be made available. My goal is 100% open source and open hardware.”
