Mouth Joystick

An assistive input device controlled by the user's mouth, lips, or tongue that functions as a pointer or gamepad joystick. The user moves a small stick held between the lips to direct cursor or on-screen movement; selection is typically triggered by a sip-and-puff switch, chin switch, or dwell. Mouth joysticks are used by people with high-level spinal cord injury, quadriplegia, ALS, severe cerebral palsy, and other conditions that preclude hand use. Modern variants integrate with PCs, tablets, powered wheelchairs, and game consoles; accessibility design should ensure that interfaces are fully navigable without requiring two-handed or precise-pointing input.
