The QuadJoy may not be a computer accessory that everyone needs, but it’s most certainly one of the strangest that we’ve come across. Simply put, it’s a mouth-operated joystick that works exactly as it sounds.
The further you move the joystick, the faster the cursor moves, while mouse button activation can be made with the built in sip and puff switch, a switch with the external switch jack or manually with the actual mouse buttons for able body assistants. Switch users can use Quadjoy with External Switch Jack for mouse button activation. QuadJoy can be mounted to most flat surfaces and is assembled to mount on the right hand side of the user,” according to the company.
