TetraMouse models offer more built-in features at the lowest price of all mouth-operated mice.

The two TetraMouse models TMXS and the new TMXA2 consist of dual joysticks that may be operated using the lip, chin, tongue or fingers. The joystick on the right controls the mouse pointer movement and is also used to change settings when in program mode, while the left joystick provides up to 8 buttons (left, right, middle and mouse buttons 4 through 8), left, right and middle button click and hold (drag and drop) functions, scrolling and auto repeat scrolling, and user controlled programming functions. The TetraMouse TMXS and TMXA2 models are standard USB mice, which means they will work on any computer, AAC device, security system, or other device capable of supporting a USB mouse input.

Rectangular Housing with Flat Front



The new, non-toxic TPU (Thermoplastic Polyurethane) knobs feel like rubber. The flange at the base of the knobs help keep moisture from the breath from entering the holes for the joystick shafts, and because they push on and pull off, they are easy to change and they never come loose, unlike the older screw-on knobs that were difficult to tighten.
