Abstract

A portable electronic device includes a three-axis acceleration sensor, a touch-sensing module, a processor, and a display screen. The three-axis acceleration sensor outputs a first sensing signal according to the state of motion. The touch-sensing module generates a touch-sensing signal according to the touch action of a touching object. The processor receives the first sensing signal and the touch-sensing signal, executes the user interface, and determines that the portable electronic device is in a state of motion when the first sensing signal is greater than a predetermined threshold. When the portable electronic device is in a state of motion, the processor continuously receives the touch-sensing signal and the user interface is in a normal mode rather than a call mode for longer than a predetermined time, the processor controls the display screen to decrease the brightness for entering a safe operation mode.
