Abstract
The purpose of this research is to invent the device that capable of obtaining visual information without direct touching the object. In this paper, we describe the prototype device consisted of a microcontroller, vibrator and distance measurement sensor. Frequency changes appropriately to distances to a target pointing the device at. Using obtainable distance and position of hand by moving the device, target's position is perceptible for user. In addition, user can consider a mental map and recognize target's shape without direct touch.
