Astyk Compact MRI Joystick

Compact, 2-Axis Fiber Optic Joystick

Works with both the 932 or 905 interfaces

All plastic construction


Astyk is a compact, 2-axis joystick with a high quality return-to-zero mechanism, with no buttons. 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. There is a less expensive, non-MR trainer available for this response pad for use outside the magnet room.

This device is a compact, 2-axis joystick with a high quality return-to-zero mechanism. Ballistic and fine finger movements can be recorded accurately with low force requirements and high responsiveness. The short shaft can be controlled well with a fingertip or thumb alone with very little or no movement of the wrist and arm. We developed this in response to customer requests for an smaller, lighter alternative to the Tethyx joystick (which is still often the better choice for VR navigation tasks, especially those requiring thumb or finger button activations) for motor neurophysiology tasks.

It is compact enough to be held in one hand for thumb use, rested on the leg, or positioned next to the leg.

    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 (BE-XX) 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.
