PORTABLE ELECTRONIC DEVICE AND UNLOCKING METHOD BY ELECTRONIC COMPASS
First Claim
1. A portable electronic device, comprising:
- a storage unit;
a display unit;
at least one processor;
an electronic compass operable to detect a rotation direction and a rotation angle of the portable electronic device by calculating an included angle of the electronic device with the Earth'"'"'s magnetic field relative to the North Pole;
one or more programs that are stored in the memory and are executed by the at least one processor, the one or more programs comprising;
a setup module operable to set a predetermined rotation direction and a predetermined rotation angle;
a receiving module operable to receive the rotation direction and the rotation angle of the portable electronic device detected from the electronic compass and to save the rotation direction and the rotation angle in the storage unit;
a checking module operable to determine whether the rotation direction and the rotation angle stored in the storage unit change within a predetermined time period;
a determination module operable to determine whether the rotation direction and the rotation angle are the same as the predetermined rotation direction and the predetermined rotation angle if the rotation direction and the rotation angle do not change within the predetermined time period; and
an unlocking module operable to control the least one processor to unlock the portable electronic device if the rotation direction and the rotation angle are the same as the predetermined rotation direction and the predetermined rotation angle.

Abstract
A method uses an electronic compass to unlock a portable electronic device. A user can rotate the portable electronic device to set a predetermined rotation direction and a predetermined rotation angle of the portable electronic device for unlocking of the portable electronic device. In an unlock procedure, the electronic compass detects the rotated portable electronic device and outputs detected information of the portable electronic device. If the rotation direction and the rotation angle of the portable electronic device are the same as the predetermined rotation direction and the predetermined rotation angle of the portable electronic device, the locked portable electronic device is unlocked.
