METHOD FOR SENSING PRESSURE BY TOUCHING

摘要

PURPOSE: A touch pressure measurement method is provided to supply the same effect with only an existed speaker and microphone and software, thereby reducing expenses. CONSTITUTION: A sound wave is generated through an output unit of a terminal. The sound wave is received through an input unit of the terminal. Pressure intensity applied to the terminal is measured by measuring a change of the sound wave inputted to the input unit. [Reference numerals] (AA,HH) Start; (BB) Generating a sound wave; (CC) Inputting a sound wave; (DD) No; (EE) Touching a touch screen; (FF) Yes; (GG) Expressing the intensity of touch according to the value of a sound wave
