Abstract
A portable electronic device adapted to change its operation mode is disclosed. When a rotation of the portable electronic device is detected, the operation mode is changed according to the angle of rotation, and a user interface corresponding to the changed operation mode is output by a display unit. This method intuitively changes the mode based on a rotation of the device without requiring a complicated and unnecessary key input, and provides a more convenient and faster user interface.
