Scroll Click

Current Designs' fMRI scroll click response device is useful in computer response tasks for 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.

The scroll wheel is a good choice for rating tasks with very little hand movement. Using the thumb, it turns back and forth, enumerating as a keyboard, sending outputs for upward rotations, wheel presses, and downward rotations. It is easy to use and fits nicely in different sized hands.

There is a less expensive, non-MR trainer available for this response pad for use outside the magnet room.

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. Examples of the interface and bundle are shown below in the Related Products section.
