In present study, we developed a tactile speed patterns presentation device that is capable of perform the tactile speed perception and discrimination experiments. It can serve to determining the underlying central neural mechanisms that contribute to tactile speed perception and discrimination. The device consists of two dots stimulus discs, one stepping motor, one motor controller and one computer. We used energy from the stepping motor to rotate the dots stimulus discs to present the different tactile speeds. The information related to rotating speed and time will be recorded with the computer. Then, five healthy subjects were asked to conduct a tactile speed estimation experiment using present device. The results indicated that the subjects underestimate the perceived tactile speed compare to the standard speed.
