Electronic device and method for unlocking the electronic device

摘要

In a method for unlocking an electronic device with a touch screen and a distance sensor, a triggering signal to unlock the electronic device is received. Objects within a predetermined distance of the distance sensor is determined. The touch screen is activated to display an unlocking area if no object is detected within the predetermined distance of the distance sensor. Touch signals are received from the unlocking area to determine whether an unlocking operation is performed. A time duration that the touch screen has been activated is calculated to determine whether the unlocking operation is performed within a preset time period from activation of the touch screen. The electronic device is unlocked if the unlocking operation is performed within a preset time period from activation of the touch screen, and a predetermined application is executed when the electronic device is unlocked.
