That is, mobile service providers are currently using wireless Internet services, short message services (SMS), multimedia messaging services (MMS), images, as well as space- and time-independent calls. , Various services such as multimedia services such as video and digital broadcasting are provided through a mobile terminal.

Such mobile terminals, in addition to the basic functions of making a call with a general subscriber or another mobile subscriber through a base station (BS) while arbitrarily moving in a mobile communication service area, manage personal information, exchange information with a computer, and the Internet. It has additional functions such as performing the same data connection. In recent years, portable terminals having improved performances such as transmission and reception of images or videos, MP3 player functions, camera functions capable of taking pictures, and digital broadcast reproduction functions have appeared on the portable terminals.

Until recently, portable terminals have undergone many changes and developments in form and function. For example, in the form, it ranges from a bar type terminal to a flip type, a folder type, a dual folder type, and a slide type terminal. In addition, the functions range from simple telephone transmission / reception functions to games, video on demand (VOD), electronic dictionaries, near field communication, MP3 playback, and digital broadcast playback.

As described above, the portable terminal includes various functions in addition to the basic call function. In order to operate the functions of the portable terminal, a keypad may be used as a predetermined user interface unit. However, as the functions of the mobile terminal become more complicated and diverse, the number of keypads is increasing, and the arrangement of the keypads is also becoming more complicated. This complex and increasing keypad as much as the above function limits the use of the portable terminal for the older generation insensitive to the use of the machine.

In addition, while the function of the portable terminal frequently used by the user is different, the function of the keypad of the portable terminal is uniform at the time of production, which may cause a lot of inconvenience to the user. In addition, portable terminals are typically convenient for right-handed users. This can cause a great deal of inconvenience when a few left-handed users or a user needs to change directions.

For example, the user may take a picture in the horizontal direction without taking a picture in the general vertical direction. That is, although the picture may be taken in the normal vertical direction, the portable terminal may be rotated by 90 degrees to take the picture in the horizontal direction.

In step S419, the control unit displays the multimedia playback screen displayed in step S401 in the changing portrait mode. An embodiment thereof is shown in FIG. 7.

As illustrated in FIG. 7, when a touch event occurs only by a part of an input unit in a current user use mode (eg, a landscape mode), the controller determines that the touch event is changed to a portrait mode and uses the user. In addition to changing the mode to portrait mode, the current screen orientation is rotated by 90 degrees. In this case, when a touch event in a clockwise / counterclockwise direction occurs in the portrait mode, the controller changes the portrait mode to a landscape mode (eg, a left hand mode, a right hand mode) according to the touch event in the clockwise / counterclockwise direction. It is desirable to.

On the other hand, if the touch event does not occur in step S403 proceeds to step S405 to determine any event (eg, multimedia playback end) and performs the corresponding operation. For example, if it is determined that the event is an end of the multimedia playback and display in progress (or the end of the function operation of the portable terminal, etc.) in step S401, the controller proceeds to step S407 to the random event. Accordingly, the multimedia playback and display are terminated, and the current user use mode is saved.
