Trackball Fiber Optic Response Pad for computer research tasks in fMRI and MEG

For the 932 and Birch interfaces

All plastic construction


Current Designs' fMRI trackball is the perfect choice for a wide range of computer response tasks used in the human brain mapping project. It 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.


  • Handheld for the FIU-932 and Birch interfaces
  • Two axis encoder control
  • Two (2) side buttons
  • Overall dimensions: 4 x 5.75 x 1.75 in. (10 x 15 x 4 cm)
  • Wide variety of outputs available for Windows, Mac and Linux computers, including several USB and serial modes.
  • 10 ft (3 m) long fiber pigtailed connector
  • Special calibration mode for the trackball.

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 bundle options 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.
