FPS models:
Both the Original and FPS models use the same software and internal electronics. The difference is the joystick gimbal. The joystick gimbal in the Original model is the same part used in ordinary game controllers connected to an aluminum rod to which the mouthpiece is attached. An extra spring is used to help hold up the weight of the mouthpiece and Lip button assembly and stiffen the movement.
In the FPS model, a larger and and more accurate joystick module is used. The centering mechanism is different and provides a more definite feel to the center position which aids the user in precise aiming. The FPS gimbals use ball bearings for the axes and magnetic Hall Effect sensors for the position sensing. This eliminates the two main sources of wear in the Original model and gives very smooth movement.
The FPS model requires more strength in the user’s lips to move. While not an issue for someone with a spinal cord injury, a user with a disability that affects the strength of the muscles in their lips may be better suited for the Original model. In the Original model, the spring and lip button assembly can be removed for users that have difficulty moving the joystick, giving it a very light feel. This is not an option with the FPS model.
The FPS mouthpiece connections use Luer fittings that can be used with Hydrophobic Syringe Filters for multi-user applications.
 Center Mouthpiece Hole Luer Fitting Connection for center hole tube. Compatible with Luer Syringe filters for multi-user applications.
