<p>PURPOSE: A vibration sensing touch input detecting method is provided to detect the movement of touch signals by detecting the movement of touch points based on the frequency and amplitude of vibration. CONSTITUTION: Exclusive vibration frequency values of four or more vibration sensing sensors are stored(S510). The occurrence of initial touch signals is detected and recognized by using the variation of the vibration frequency values sensed by a vibration sensing sensor(S520). The movement of the touch signals is detected and recognized by comparing the variation values of the frequency and amplitude values sensed by two or more sensing sensors(S530). The vibration sensing sensors are embedded into inside touch screen apparatuses.</p> |
