Abstract
An electronic device includes a touch-screen, an infrared emitter, an infrared sensor and a control module. The touch-screen is configured for displaying a interface with various touchable items. The infrared emitter is configured for emitting infrared light. The infrared sensor is configured for receiving reflected infrared light, and for generating an electrical signal according to the reflected infrared light. The control module is configured for receiving the electrical signal and determining whether the value of the electrical signal is higher than a standard value. If the value of the electrical signal is higher than the standard value, the control module is further configured for invoking the touch interface on the touch-screen.
