(a) The tactile pattern delivery device used in the fMRI experiment. During the experiment, the hands of subject were fixed on the device by a hand fix block, and the index fingers of subject were fixed by the index finger holder and index finger platelet. In addition, the subjects were able to do the “Press, Release” procedure smoothly due to a plastic spring as shown in (1) (2) and (3). (b) The hand position and tactile pattern contact location on the finger tap. For the angle pattern: the imaginary bisector of angle is perpendicular to the centre line of finger. For the MSC pattern: the raised lines were parallel to the long axis to the finger.
