Abstract:
A tactile presentation device is provided with: a glove worn on the hand of a user; polymer actuators attached to a base fabric of the glove; a control device which controls the polymer actuators; and an array of haptic stimulators driven by the polymer actuators. The tactile presentation device drives the haptic stimulators using the polymer actuators through the application of a voltage to the polymer actuators by means of the control device, and performs tactile presentation to the skin of the hand of the user by driving the haptic stimulators. The polymer actuators are capable of causing the haptic stimulators to be displaced by at least 100 μm when the frequency of the applied voltage is 1 to 30 Hz and more preferably 1 to 100 Hz.
