DETAILED DESCRIPTION OF EMBODIMENTS
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. Exemplary embodiments are described below by referring to the figures.
FIG. 1 is a block diagram of a portable terminal according to an exemplary embodiment. Referring to FIG. 1, the portable terminal may comprise a contents creator 110, a tag generator 120, a storage unit 130, a controller 140, a main display unit 150, and a plurality of buttons 160. The controller 140, the main display unit 150, and the buttons 160 may be included in a portable terminal (portable device) such as a mobile phone, digital camera, portable media player (PMP), or a personal digital assistant (PDA), whereas the contents creator 110, the tag generator 120, and the storage unit 130 may be embedded in the portable terminal or externally provided (e.g., connected to the portable terminal over a network). For the convenience of description, however, the contents creator 110, the tag generator 120, and the storage unit 130 are embedded in the portable terminal.
The contents creator 110 creates contents that can be reproduced by the portable terminal. Examples of contents are photos, video, music, and the like. When contents are created, the contents creator 110 controls the operation of the tag generator 120.
The tag generator 120 generates one or more tags that match the contents created by the contents creator 110. Tags are information being considered keywords of the contents.
The tag generator 120 can generate a tag that is thought of by a user (e.g., contents creator) who operates the portable terminal, according to the operation of buttons. The tag generated by the tag generator 120 is a word that is considered by a creator of the contents to be a keyword of contents. The tag is generally information determined subjectively based on the contents creator.
The tag generator 120 can automatically generate a tag according to a predetermined process irrespective of a user's intention. For example, the tag generator 120 can generate a tag indicating the date on which contents are created or a tag indicating its position coordinate found through a global positioning system (GPS) of the portable terminal including the contents creator 110. In this regard, the user is not aware of the generation of the tag.
The storage unit 130 matches the contents created by the contents creator 110 and the one or more tags generated by the tag generator 120, and stores the matched contents and tags. In the present exemplary embodiment, a tag of the contents is a tag matching the contents.
In this way, the storage unit 130 can store a plurality of pieces of contents and a plurality of tags matching the contents. In this regard, the storage unit 130 may store arrangement information necessary for arranging the plurality of tags. There are various types of arrangement information. For example, the arrangement information can be information indicating that a plurality of tags are arranged in alphabetical order, or in order of generation. The storage unit 130 can store a plurality of pieces of arrangement information.
The controller 140 can provide the main display unit 150 with a plurality of prepared tags and a plurality of pieces of prepared arrangement information and provide the buttons 160 with one or more pieces of prepared contents, or provide the main display unit 150 with prepared contents and provide the buttons 160 with one or more prepared tags. As indicated above, the prepared tags are stored in the storage unit 130, and the prepared arrangement information is stored in the storage unit 130. The controller 140 reads the at least one tag, arrangement information, or contents from the storage unit 130 to provide the buttons 160 with them.
The main display unit 150 corresponds to a main window of the portable terminal. The buttons 160 correspond to sub windows of the portable terminal. The main display unit 150 and the buttons 160 have a display function. The buttons 160 includes a first button 160-1, a second button 160-2, . . . and an Nth button 160-N (N is an integer greater than 2). The portable terminal can include the buttons 160 having the display function and a button (not shown) having no display function as well.
The operation of the main display unit 150 and the buttons 160 will now be described in more detail.
The main display unit 150 arranges the plurality of prepared tags according to a predetermined standard, and displays the arranged tags. In more detail, the main display unit 150 arranges the plurality of prepared tags based on the prepared arrangement information, and displays the arranged tags. The arrangement information provided by the controller 140, i.e., the arrangement information on which the main display unit 150 is based, may be selected by the user from the arrangement information stored in the storage unit 130. If the storage unit 130 stores both “arrangement information indicating that the plurality of tags are arranged in alphabetical order” and “arrangement information indicating that the plurality of tags are arranged in the order of their generation”, the user who prefers the plurality of tags arranged in alphabetical order to the plurality of tags arranged in the order of their generation can properly operate the buttons of the portable terminal to instruct the main display unit 150 to be based on the “arrangement information indicating that the plurality of tags are arranged in alphabetical order”.
If the tags stored in the storage unit 130 cannot be displayed on the main display unit 150 at the same time, the main display unit 150 can first display some of the tags, and, if the user operates a button such as a direction key, it can then display the other tags. The direction key can be a button 160-n (n is an integer 1≦n≦N) having the display function, or a button having no display function.
If the main display unit 150 displays the plurality of tags, the user may select a “tag that is supposed to be included in specific contents to be searched among the prepared contents” from the displayed tags. To this end, the user can operate the button such as the direction key. Even if the user does not select a tag from the displayed tags, one of the displayed tags, e.g., a first tag of the displayed tags, is set as default.
When the main display unit 150 displays the plurality of tags, the buttons 160 displays one or more pieces of contents having “a tag selected from the displayed tags” among the plurality of pieces of prepared contents. In this regard, the main display unit 150 and the buttons 160 may simultaneously operate. If the button 160-n displays a photo, the photo is displayed in the form of a thumbnail image. If the button 160-n displays video, a still image of the video is displayed in the form of the thumbnail image. If the button 160-n displays music, information, e.g., a title of the music, on the music is displayed.
If the plurality of contents displayed on the buttons 160 does not include content that the user is searching for, the user operates the button such as the direction key to select a tag other than the currently selected tag. In this regard, the buttons 160 displays one or more pieces of contents having the “tag” selected by the user among the plurality of pieces of prepared contents. As mentioned above, when the main display unit 150 displays the plurality of tags based on the arrangement information that the user prefers, the user may select a tag to be displayed closest to the currently selected tag.
If the plurality of contents displayed on the buttons 160 includes content for which the user searches, the user operates a button on which the contents are displayed to select the contents. In this regard, the main display unit 150 does not display the tags any longer but displays an enlarged version of the contents for which the user searches. At the same time, the buttons 160 does not display the contents any longer but displays one or more tags of the contents for which the user searches.
Thereafter, if the user selects a tag from the tags displayed on the buttons 160, the main display unit 150 does not display the contents any longer but displays the plurality of tags including the tag selected by the user among the plurality of prepared tags, and the buttons 160 does not display the tags any longer but displays one or more pieces of contents having the tag selected by the user among the plurality of pieces of prepared contents.
The operations of the controller 140, the main display unit 150, and the buttons 160 may be initiated when the user who searches for one of the contents stored in the storage unit 130 using the portable terminal operates a search instruction button (not shown) of the portable terminal, and terminated when the user does not operate a button of the portable terminal after a predetermined threshold time has elapsed. The search instruction button (not shown) can be a button having the display function such as the button 160-n or a button having no display function.

The plurality of prepared tags are arranged according to arrangement information on which the main display unit 230 is based. Since the tag “sea” is selected, the buttons 240 can display 12 pieces of contents having the tag “sea” among a plurality of pieces of prepared contents.
Likewise, referring to FIG. 2B, if the tag “food” is selected, the buttons 240 can display 12 pieces of contents having the tag “food” among the plurality of pieces of prepared contents.
If a button 250 displays contents for which the user searches, the user can operate the button 250 to select the contents. In this regard, referring to FIG. 2C, the main display unit 230 displays an enlarged version of the contents selected by the user, and the buttons 240 displays one or more tags (food, Japan, Appetizers, and kanbariya) of the contents selected by the user.
The user can search contents relating to the selected contents while seeing the main display unit 230 and the buttons 240. For example, if the selected contents are a photo of food the user had while the user traveled in Japan, the user accidentally wants to see a photo relating to the photo of food among photos taken at that time and searches for the photo.
The user selects the tag “Japan” from the tags shown in FIG. 2C. Referring to FIG. 2D, the main display unit 230 displays a plurality of tags including the tag “Japan” among the plurality of prepared tags, and the buttons 240 display 12 pieces of contents having the tag “Japan” among the prepared tags. If a button 260 displays content that is the photo for which the user is searching, the user operates the button 260 to select the photo. The main display unit 230 displays an enlarged version of the photo, and the buttons 240 display one or more tags of the photo.
