Fiber Optic Finger Stick	Joystick with Grip	The change is easily made.

Current Designs' Fiber Optic Joystick is designed to give a joystick/game controller option for use in special environments like MRI or MEG where metal or electronics could hinder data acquisition, degrade image quality, or pose safety risks. The all-plastic joystick works on light signals from our electronic interface which is placed outside the magnet or MEG room. A complete system includes the joystick handheld, an interface and the removable fiber optic bundle.

Fiber optic joystick system includes the electronic interface, 12-fiber bundle, and the joystick.

The joystick produces movement whenever it is moves away from the center, so it is less easily controlled.
There is a short initialization period when it is turned on when the joystick should be stationary. There is a good
neutral spot which will roduce no movement. The buttons are just like those on our button boxes.

The trackball only produces movement when it is turned, so it is more easily controlled. It does require a light touch
and should be used before the task. The buttons are less definite than the joystick buttons.

Generally, the joystick works better as a game controller and the trackball works better as a mouse.
