This would be a device for those who are physically paralyzed from the neck down or do not have motor functions in the arms and wrist.  Essentially, this would be a hat that can sense tilt of a person’s head using an accelerometer and send commands to a computer via USB to control a cursor similar to a joystick.   To click, the user bites down on a force sensor located in the person’s mouth.  The accommodating circuitry would be sewn to a hat of the user’s choice.

Some challenges one may encounter when pursuing this project include the accuracy of movements, calibration, and sensitivity to small head movements.
