CYL Joystick Fiber Optic Response Pad with No Buttons

All plastic construction


Current Designs' fMRI CYL Joystick is non-magnetic, non-electronic, and entirely made out of plastic, so will not add noise to the images or raise safety concerns in the MR/MEG room or similarly demanding environments.

This joystick closely resembles the Tethyx joystick, but has a cylindrical shaft rather than the ergonomic Tethyx shaft. This joystick has no buttons. Note: because it is less popular, it may not be in stock and can take extra time to deliver.

X,Y Range Features

Tethyx is normally provided with a square range of motion covering approximately +/- 15 degrees in X and Y, but a removable plastic plate in the bottom cover makes it easy to change this range for different task needs. For example, a circular range might be better for some task, or possibly a straight line in only X or only Y would be better. Please get in touch to let us know if you are looking for a particular range.

Return to Zero

An internal non-magnetic spring forces the shaft back to its vertical resting position when released.

What Else Is Needed

This handheld response device needs an electronic interface to function -- that converts the optical signals to standard computer interfacing signals. In most cases you will also need a long optical fiber extension bundle to allow this device to be used at a distance from the interface unit. The required interface and compatible bundles are shown below in the Related Products section.

This item contains no metal, nothing electronic, and nothing magnetic. It can be used safely in the magnet room.
