Applications of a miniature pin-array tactile module for a mobile device

Tactile sensation in the mobile device has been generated by vibration motors because of the size and the power consumption of a tactile module. However, the vibration motor is not enough to provide detail texture or small-scale shape. Therefore, we developed a miniature pin-array tactile module which can be embedded into a mobile device using the elastic and the electromagnetic force. In this paper, the various applications of the pin-array tactile module in the mobile device are presented. The pin-array tactile stimulating system plays important roles such as a braille display, a various alarming system, walking aid.
