Abstract
In the fMRI experiments, there is a need for the input device that has good operability. So, in this research, with due consideration for the operability in the MRI environment, we developed the five button switches whose exterior fit your hand, and two-dimensional joystick using gimbal mechanism. These one-handed controllers have good operability in the MRI environment because they were designed based on the sense of use in the mock-up of the MRI machine. And we confirmed that these one-handed controllers had no influence on MRI imaging, and functioned well in the MRI environment. It's hoped that these one-handed controllers are effectively-utilized in the various fMRI experiments.
