     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0058]    Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures. 
         [0059]      FIG. 1  is a block diagram schematically illustrating a user interface device according to an embodiment of the present general inventive concept. 
         [0060]    Referring to  FIG. 1 , the user interface device according to an embodiment of the present general inventive concept includes a command input unit  100 , a menu storage unit  110 , a display unit  130 , an icon storage unit  150 , and a control unit  170 . 
         [0061]    The command input unit  100  receives various kinds of commands from a user, and transfers the received commands to the control unit  170  to be described later. The command input unit  100  is provided with a human interface, such as a plurality of manipulation keys required for a user to search menus and enter signals corresponding to the command. The command input unit  100  may receive a user command transmitted from an external manipulation device and transfer the received user command to the control unit  170 , 
         [0062]    In the menu storage unit  110 , menus constituting a user interface and arrangement states of the menus are stored. Also, the structure of the user interface set by a setting command is stored in the menu storage unit  110 . In the icon storage unit  150 , one or more variously shaped prompt icons in the form of a circular plate, loop, and star, for example, to correspond to the menus are stored. 
         [0063]    The control unit  170  generates the user interface by combining the menus stored in the menu storage unit  110  with the prompt icons stored in the icon storage unit  150 . The generated user interface is displayed on the display unit  130 , and a user can search for a desired menu as the user views the user interface displayed on the display unit  130 . 
         [0064]    The control unit  170  may generate the user interface with a predetermined arrangement. If a user inputs a search command by manipulating a specified key in order to search for a desired menu, the control unit  170  controls the searched menu and the corresponding icon to be enlarged and displayed on the display unit. The control unit  170  may control a conspicuous image, such as a continuously glittering prompt icon, for example, to be displayed on one side of the searched menu. 
         [0065]    In addition, the control unit  170  adjusts a position of an upper menu being displayed on the display screen as the menu moves to sub-menus, and thus the user can be more fully aware of the progress of the selected menu. 
         [0066]    The implementation of the user interface as described above may be performed by a user interface (UI) generation unit (not illustrated) included in the control unit  170 . The user interface generation performed by the control unit  170  will be explained in more detail with reference to  FIGS. 2A to 5 . 
         [0067]      FIGS. 2A to 2D  are exemplary views illustrating the structure of a user interface displayable on a screen of a display device according to an embodiment of the present general inventive concept. 
         [0068]      FIG. 2A  shows a user interface in which upper menus (e.g., Photo, Music, Movie, DMB (digital multimedia broadcasting), and Settings) are arranged, for example, on a vertical line. Referring to  FIGS. 1 and 2A , when a user inputs a search command for menu search through the command input unit  100 , a first prompt icon  200  is displayed, preferably, but not necessarily, on one side of the menu that is being searched. The first prompt icon  200  is shown in  FIG. 2A , for example, as being displayed as a continuously glittering ray, and may take on other diverse forms such as a circular plate, loop, star, and so forth. The first prompt icons  200  are stored in the icon storage unit  150 , and the user can select and use the first prompt icon  200 . 
         [0069]    Referring to  FIG. 2B , with the movement of the first prompt icon  200 , the upper menus (e.g., Photo, Music, Movie, DMB, and Settings) are scrolled up and down for the case when the menus are aligned in a vertical pattern. Only the menu (e.g., Movie) selected by the selection command inputted by the user is displayed on the screen, and other menus (e.g., Photo, Music, DMB, and Settings), except for the selected menu (e.g., Movie), may disappear or be de-emphasized from the screen. At this time, the first prompt icon  200 ′ is displayed on one side of the selected menu with a reduced or altered state, for example, a fixed brightness, i.e., without continuously glittering. 
         [0070]    After the non-selected upper menus (e.g., Photo, Music, DMB, and Settings), are altered, sub-menus (e.g., Personal Movie, Animation, Action/SF, Drama, and The Last Movie) of the selected upper menu (e.g., Movie) are displayed, as shown in  FIG. 2C . 
         [0071]    If the user proceeds to input a search command through the command input unit  100  for the menu search, a second prompt icon  250  is displayed on one side of the sub-menu selected among the sub-menus (e.g., Personal Movie, Animation, Action/SF, Drama, and The Last Movie), in a similar manner as the upper menus (e.g., Photo, Music, Movie, DMB, and Settings). Here, the user can set the second prompt icon  250  so that it is displayed with a form or size different from the first prompt icon  200 . The second prompt icon  250  may be smaller than or different from the first prompt icon  200 ′ in size or form. 
         [0072]      FIG. 2D  shows examples of the user interface according to an embodiment of the present invention. The background of the user interface and the form or arrangement of the menus as illustrated in  FIG. 2D  are stored in the menu storage unit  110 , and then changed and displayed on the screen according to the user&#39;s command. Also, the form of the prompt icons  200 ,  200 ′, and  250  are stored in the icon storage unit  150 , and then changed and displayed on the screen, together with the menus, according to the user&#39;s command. 
         [0073]      FIGS. 3A to 3D  are exemplary views illustrating a user interface displayable on a screen of a display device according to another embodiment of the present general inventive concept. 
         [0074]      FIG. 3A  illustrates a user interface, in which upper menus (e.g., Photo, Music, Movie, DMB, and Settings) are perspectively arranged on a first ring  300  having a perspective appearance. Icons corresponding to the perspectively arranged upper menus (e.g., Photo, Music, Movie, DMB, and Settings) are also three-dimensionally displayed on the screen. Referring to  FIGS. 1 and 3A , if a user inputs a search command for menu search through the command input unit  100 , the upper menus (e.g., Photo, Music, Movie, DMB, and Settings) are rotated around a center axis C, and the searched upper menu (e.g., Photo) is displayed on the screen, as illustrated in  FIG. 3A . That is, the searched upper menu (e.g., Photo) and the corresponding icon are displayed on the center axis C with an enlarged appearance compared to other upper menus, so that the searched upper menu and the corresponding icon appear to be in a position which is closest to the user. 
         [0075]    When the searched upper menu (e.g., Photo) with the corresponding icon is positioned on the center axis C, first sub-menus (e.g., User Folder, Daily, Weekly, Monthly, and Photo-list) are displayed at the forefront of the screen as illustrated, for example, in  FIG. 3B . That is, the size of the first ring  300  and the sizes of the upper menus (e.g., Photo, Music, Movie, DMB, and Settings) and corresponding icons arranged on the first ring  300  become smaller, and a second ring  330  having a perspective appearance of the first sub-menus is formed around the first ring  300 . 
         [0076]    The first sub-menus (e.g., User Folder, Daily, Weekly, Monthly, and Photo-list) are perspectively arranged on the second ring  330 . The first sub-menus (e.g., User Folder, Daily, Weekly, Monthly, and Photo-list) arranged on the second ring  330  may be rotated around the center axis C according to the user&#39;s search command, and the searched sub-menu (e.g., User Folder) with the corresponding first prompt icon  310  is displayed on the center axis C with an enlarged appearance compared to other first sub-menus. As illustrated in  FIG. 3B , the first prompt icon  310  may be displayed on the screen as a continuously glittering ray, for example. 
         [0077]    If the searched sub-menu (e.g., Monthly) is selected among the first sub-menus (e.g., User Folder, Daily, Weekly, Monthly, and Photo-list), second sub-menus (e.g., 2005.06˜2006.01) are displayed on the screen as illustrated in  FIG. 3C . That is, as the sizes of the first ring  300  and the second ring  330  become smaller, a third ring  370  having a perspective appearance is formed around the second ring  330 . 
         [0078]    The second sub-menus (e.g., 2005.06˜2006.01) are perspectively arranged on the third ring  370 . The second sub-menus (e.g., 2005.06˜2006.01) may be rotated around the center axis C according to the user&#39;s search command, and the searched second sub-menu (e.g., 2005.06) and the corresponding second prompt icon  350  are displayed on the center axis C, with an enlarged appearance compared to other second sub-menus and may also be given the attribute, of a continuously glittering ray, for example. 
         [0079]    Here, the icons corresponding to the first sub-menus (e.g., User Folder, Daily, Weekly, Monthly, and Photo-list) and the second sub-menus (e.g., 2005.06˜2006.01) represent styles or shapes of light, which may have diverse forms such as a circular plate, loop, star, and so forth. The icons having diverse forms as described above are stored in the menu storage unit  150 , and the user can select and use the stored icons. 
         [0080]    As illustrated in  FIG. 3C , the respective menus are arranged similar to that of planets revolving round a fixed star, or some variation thereof. Specifically, the upper menus, the first sub-menus, and the second sub-menus are respectively arranged on the first ring  300 , the second ring  330 , and the third ring  370 , which have a common center, and thus the user can quickly confirm the position of the selected menu with respect to the other various menu items. The background of the menus, font and the form of the prompt icon, for example, can be changed according to the user&#39;s desire. 
         [0081]      FIG. 3D  illustrates three dimensional user interface actually implemented on the display screen in accordance with the structures as illustrated in  FIGS. 3A to 3C . The background of the menus, font and the form of the prompt icon, as illustrated in  FIG. 3D , can be changed according to a user&#39; command. 
         [0082]      FIGS. 4A to 4E  are exemplary views illustrating the structure of a user interface according to still another embodiment of the present general inventive concept. A 
         [0083]      FIG. 4A  shows a user interface, in which upper menus (e.g., Photo, Music, Movie, Sharing, and Settings) and their corresponding icons are arranged on a ring  400 . The menu (e.g., Music) searched in accordance with a search command is positioned in a place S where a vertical axis L and a horizontal axis W meet each other, and the searched upper menu (e.g., Music) with the corresponding icon is displayed with a size larger than those of other non-searched menus (e.g., Photo, Movie, Sharing, and Settings) and their corresponding icons. 
         [0084]    When the user selects the searched menu (e.g., Music), the vertical axis L is moved to the left and all the upper menus (e.g., Photo, Music, Movie, Sharing, and Settings) are moved to the left, as illustrated, for example, in  FIG. 4B . After the movement of the upper menus, first sub-menus (e.g., Best Music, Music list, Artists, and Album) of the selected upper menu (e.g., Music) are arranged on the horizontal axis W. 
         [0085]    In accordance with the user&#39;s search command, the searched first sub-menu (e.g., Best Music) among the first sub-menus (e.g., Best Music, Music list, Artists, and Album) is displayed with a more conspicuous attribute, for example with an increased size, brightness, and/or darkness than of the other non-searched menus (e.g., Music list, Artists, and Album), and thus the user can visually confirm the selection of the menu being searched as well as easily view the location of the nearby menus/sub-menus. 
         [0086]    Referring to  FIG. 4C , second sub-menus (e.g., Blue, Dream, Jackson, Ash, and John) of the menu (e.g., Album) selected among the first sub-menus (e.g., Best Music, Music list, Artists, and Album) are arranged along a first arc C 1 . The searched menu (e.g., Jackson) among the second sub-menus (e.g., Blue, Dream, Jackson, Ash, and John) is positioned on the horizontal axis W, and a preview image that corresponds to the searched menu (e.g., Jackson) is displayed on the right part of the screen. 
         [0087]    If the searched menu (e.g., Jackson) is selected, then as shown in  FIG. 4D , third sub-menus (e.g., 1. Ready, Get Set, Go!; 2. Super fantastic; 3. Everything is OK; 4. April Funk (june mix); 5. Bike; 6. Ready, Get Set, Go!; 7. Heavy Sun Heavy Moon) are arranged along a second arc C 2 . If the sub-menu (e.g., 3. Everything is OK) is positioned on the horizontal axis W and selected, then fourth sub-menus (shown in  FIG. 4D  as symbols corresponding to: Reverse skip; Reverse; Play/Pause; Stop; Fast Forward; and Forward skip, (e.g., |                    ,                              ∥, ▪,                    ,                     |, +) are displayed along a second arc C 3 . The searched menu (e.g.,          ∥) among the fourth sub-menus (e.g., |                    ,                              ∥, ▪,                    ,                     |, +) is positioned on the horizontal axis W, and if the menu (e.g., ≮ ∥) is selected according to the selection command, an explanation or status of the sub-menu item (e.g., Play/Pause) is displayed, and the selected sub-menu in the next upper menu (e.g., 3. Everything is OK) is activated or operated on by the current sub-menu item (e.g., played or paused). While  FIG. 4D  shows the menus and sub-menus in the context of a music player with some of the menus/sub-menus operating only as informational nodes (e.g., Artist&#39;s name, Album name, etc.) segueing into other menus/sub-menus, and some of the menus/sub-menus operating as a functional menu (e.g., play function/pause function, etc.), alternative information-functions-operations may be implemented, according to design preference and to the capabilities of the electronic appliance. 
         [0088]      FIG. 4E  illustrates an example of another user interface according to an embodiment of the present general inventive concept in which the horizontal axis W and the vertical axis L have been modified. The menu (e.g., Music) searched according to the search command is positioned in a place S where the vertical axis L and the horizontal axis W meet each other, and the searched menu (e.g., Music) and the corresponding icon are displayed with a modified attribute (e.g., size is enlarged) to those of the non-searched menus (e.g., Photo, Movie, Sharing, and Settings) and to the corresponding icons. The sub-menus selected according to the user&#39;s command are displayed on the user input  405  in a manner similar to those discussed above. 
         [0089]      FIG. 5  is an exemplary view illustrating a setting menu to change a design of a user interface according to an embodiment of the present general inventive concept. 
         [0090]    Referring to  FIG. 5 , a configuration or setting menu (e.g., GUI Customizing) to change the design or layout of the user interface is included in a system setting menu (e.g., System Setting) of a setting menu (e.g., Setting). The user can additionally change the visual appearance of the menus/sub-menus of the user interface as well as the font, style, size of characters, colors, etc., that constitute the menus, through the setting menu (e.g., GUI Customizing). 
         [0091]    It should be appreciated that the menu arrangement can be changed to an arrangement on a vertical line or a curve, and the form of the icon corresponding to the menu can be changed as well. In addition, the glittering prompt icons  200  and  250 , as described above with reference to  FIGS. 2A to 2C , can be set to be in the form of a circular plate, loop, star, and so forth. Such settings are not limited to those as illustrated in  FIGS. 2A to 2C , but can be applied to other embodiments of the present general inventive concept. 
         [0092]    Exemplary embodiments, processes and procedures of the present general inventive concept can be software implementable as a program/instruction/code in resident memory or in removable memory, such as computer readable recording media, which can be implemented in various electronic appliances. Examples of the computer-readable recording medium can be magnetic storage media (e.g., ROM, floppy disks, hard disks, etc.), optical recording media (e.g., CD-ROMs, or DVDs), and storage media such as RAM, Flash, Secure Digital, Memory Stick®, etc. The computer-readable recording medium can also be distributed over network coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. Also, functional programs, codes, and code segments for accomplishing embodiments of the present general inventive concept can be easily construed by programmers skilled in the art to which the present general inventive concept pertains. 
         [0093]    As described above, according to various exemplary embodiment of the present general inventive concept, the user interface is implemented enabling a user to easily find the position of a selected menu, and thus the user can easily manipulate the functions of electronic appliances. In addition, the user interface is implemented with a greater degree of customability, and thus it can prevent the user from feeling bored from use of the electronic appliances. 
         [0094]    Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
