Abstract
A method executes an altimeter function to unlock a portable electronic device. A user can move the portable electronic device in an up-down direction to set a predetermined changed height for unlocking the portable electronic device. In an unlock procedure, an altimeter detects a changed height of the portable electronic device and outputs detected information of the portable electronic device. If the changed height is the same as the predetermined changed height, the locked portable electronic device is unlocked.

4. An computer-implemented method for unlocking a portable electronic device, the portable electronic device comprising a storage unit, a display unit and at least one processor, the method comprising:
-
detecting a height of the portable electronic device; receiving the height and saving it as an original height to the storage unit; detecting the height of portable electronic device by an altimeter continually; receiving the detected height from the altimeter, calculating a changed height by the processor and saving the changed height to the storage unit; determining whether the changed height stored in the storage unit changed within a predetermined time period; determining whether the changed height is the same as a predetermined changed height if the changed height changed within the predetermined time period; and unlocking the portable electronic device if the changed height is the same as the predetermined changed height. - View Dependent Claims (5, 6, 7, 8)
