touch screen multi touch

touch screen multi touch. The received waveform attenuates a gap corresponding to the signal blocked by the finger. To calculate the gap position, you must touch the coordinate controller to analyze the attenuation of the received signal and determine the X coordinate from the gap position . After that, the same process of the Y axis determines the Y coordinate of the touch point . In addition to the X and Y coordinates that general touch screens can respond to , the surface acoustic wave touch screen also responds to the third axis Z coordinate, which can sense the user's touch pressure value. The principle is calculated from the attenuation at the received signal attenuation.
