Abstract: An apparatus and method is provided for a mobile terminal with a rotating key having a plurality of dome switches on one side which can detect a contact signal when pressed and a plurality of contact surfaces on the other side which can detect the position of the rotating key in each direction of rotation. The apparatus and method for using the rotating key comprise the steps of detecting if the rotating key is turned or a dome switch is pressed in a menu selection mode; when the rotating key is turned, selecting a menu according to the direction of rotation; and when a dome switch is pressed, selecting a menu according to the pressed dome switch.

Abstract: An apparatus and method for displaying a picture in a mobile terminal is provided. The apparatus and method comprises a direction detecting section comprising at least one magnet fixed within the mobile terminal and a plurality of sensors for detecting the magnet in order to detect the direction in which the mobile terminal is turned and generate a first direction detecting signal, a second direction detecting signal, a third direction detecting signal, and a fourth direction detecting signal; a control section for outputting picture data in an upright direction when the first direction detecting signal is generated, in a direction turned 90° counter-clockwise when the second direction detecting signal is generated, in a direction turned 180° when the third direction detecting signal is generated, or in a direction turned 270° counter-clockwise when the fourth direction detecting signal is generated; and a display section for displaying the picture data.
