System and method of recognizing a touch event on touch pad by measuring touch area of touch sensitive surface of the touch pad

摘要: System and method of recognizing a touch event on resistive pad having virtual keys are provided. The system includes sensitive unit in the pad; area calculation unit; microprocessor. In response to pressing one by an object, measures object key, is compared with predetermined value, generates signal if greater than transmitted microprocessor, after receiving signal, microprocessor key code corresponding being pressed, computer for further processing recognize event.
