A pin-array tactile display is developed as a method of presenting tactile sensations that we experience when we stroke our fingers on the surface of objects. Important requirements for pin-array tactile displays include the frequency response up to 300 Hz, the high pin density, the independent controllability of each pin, the compact size, and the light weight. While it is essential for wearable devices, especially from the viewpoint of portability and usability, to be small and lightweight, the high-frequency response and high pin density often result in a larger size of a device. In this paper, we propose a pin-array tactile display using Shape-Memory Alloy (SMA) actuators arranged in high density, which is characterized by the high-frequency response, the independent controllability of pins, and the compactness. The performance of the device is evaluated by user experiments to examine the relationship between the control parameters and the presented tactile sensations.
