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