The fiber optic joystick was purchased from Current Designs.  The fiber optic joystick is constructed of all plastic, working entirely on light. The response device connects to the electronic interface using the removable fiber optic bundle. The complete system includes the joystick, the interface, removable fiber optic bundle, and power supply and computer cables.  The system can also interface with any of the other response box designs available from Current Designs.  For example, SLEIC has also purchased two four-button response boxes from Current Designs, compatible with the same interface as the joystick.
