TOUCH SENSOR SYSTEM USING OF TOUCH POINT VIBRATION

摘要

PURPOSE: A touch sensor system using a vibration of a hit point is provided to accurately and quickly check the position of a hit point on a touch plate and be applied to various devices using a simple and easy structure. CONSTITUTION: First and second sensor bars(11,12) include a lattice composed of piezoelectric materials. A touch plate includes the first and the second sensor bars in the vertical and horizontal sides. A signal processing unit(30) is connected to the first and the second sensor bars to receive an electric signal. A hit point calculating unit(40) calculates a touch position on the touch plate from the electric signal. The hit point calculating unit includes a storage unit storing information about the lattice and a lattice information analyzing unit calculating the position of a hit point based on the information stored in the storage unit.
