Further,FIGS. 5A and 5B, andFIGS. 6A and 6B are diagrams illustrating screens that display representative information when scrolling content according to an exemplary embodiment of the present invention.
• With reference toFIG. 4, firstly, content is displayed on a display unit inoperation1010. Thecontroller110 of theelectronic apparatus100 displays the content on the display unit. Further, the content may be calendars executed in a calendar application, photographs executed in a gallery application, pages of a book executed in an e-book application, and list items included in a list view.FIGS. 5A and5B, andFIGS. 6A and 6B are diagrams illustrating examples in which theelectronic apparatus100 is a mobile device, and the content is a calendar executed in a calendar application. With reference toFIGS. 5A and 5B, andFIGS. 6A and 6B, thecontroller110 of the mobile device may display the content corresponding to the calendar executed in the calendar application on thedisplay unit190. In addition, the display unit may be formed to thetouch screen190. Accordingly, thecontroller110 executes the calendar application, and displays the calendar on thetouch screen190. With reference toFIG. 5A, acalendar200 resulted from a calendar application is displayed on thetouch screen190. For example, thecontroller110 may display atitle202, a month andyear204, and adate206 of the calendar application by executing the calendar application. In addition, thecontroller110 may display aschedule208 stored in thedate206. At this point, thecontroller110 may display thecalendar200 on the upper portion of thetouch screen190, and theschedule208 displays thecalendar200 on the lower portion of thetouch screen190. For example, thecontroller110 may display thecalendar200 corresponding to March, on thetouch screen190.
• Subsequently, a gesture of scrolling the content is detected inoperation1020. Thecontroller110 may detect the gesture of scrolling the content. At this point, the gesture may be a drag or a flick with respect to the content on the touch screen that forms the display unit. Further, the gesture may be a drag or a flick of a scroll bar.
• For example, as illustrated inFIG. 5B, the gesture may be a drag or aflick300 with respect to the content on the touch screen. That is, thecalendar200 corresponding to the content may be displayed on thetouch screen190, as described above. At this point, the gesture may be the drag or theflick300 with respect to the calendar. For example, as illustrated inFIG. 6B, the gesture may be the drag or theflick300 with respect to the calendar in an upward or downward direction.
• Subsequently, if the gesture is detected, scrolling of the content is started inoperation1030. Thecontroller110 may start to scroll the content, if the gesture is detected. For example, the gesture may be the drag or flick300 with respect to the calendar as illustrated inFIG. 5B. Accordingly, thecontroller110 may start to scroll the calendar if the gesture corresponding to the drag or theflick300 with respect to the calendar is detected.
• For example, if the drag or theflick300 with respect to the calendar in the upward direction is detected as illustrated inFIG. 5B, thecontroller110 may start to scroll the calendar as illustrated inFIG. 6A. At this point, the drag or theflick300 with respect to the calendar in the upward direction may be a gesture of displaying the next month of the calendar. Accordingly, thecontroller110 may start to perform scrolling to display the next month of the calendar, in response to the drag or theflick300 with respect to the calendar in the upper direction. For example, thecontroller110 may start to perform scrolling to display April corresponding to the next month of the calendar, in response to the drag or theflick300 with respect to the calendar in the upper direction as illustrated inFIG. 6A. Accordingly, thecontroller110 scrolls a calendar corresponding to March in the upper direction so that the calendar corresponding to March disappears, and simultaneously scrolls a calendar corresponding to April so that the calendar corresponding to April appears. For example, thecontroller110 scrolls the calendar corresponding to March in the upper direction so that the first to third weeks of March disappear, and simultaneously scrolls the calendar corresponding to April in the upper direction so that the first to third weeks of April appear, as illustrated inFIG. 6A.
• However, as the content is started to be scrolled, the content may not be easily recognized by the user due to the movement according to scrolling. That is, due to the movement according to scrolling the content, it may be difficult for the user to recognize what content is being displayed. For example, due to the movement according to scrolling the calendar, it may be difficult for the user to recognize which month the calendar displays as illustrated inFIG. 6A.
• Subsequently, representative information of the content is extracted inoperation1040. Thecontroller110 may extract the representative information of the content. At this point, thecontroller110 may extract information with the highest priority among plural items of information included in the content, as the representative information. At this point, the representative information may be fixed information, variable information, or user designated information. At this point, the fixed information refers to information of which the priority is fixed and does not change. In contrast, the variable information refers to information of which the priority can be changed. Further, the user designated information refers to information of which the priority is input by the designation of the user. Further, the fixed information may be a title, a tag, or a table of contents of the content. In addition, the variable information may be the number of views of the contents or the number of touch events.
• Thestorage unit175 may store plural items of information included in the contents. Further, thestorage unit175 may store priorities corresponding to respective plural items of information. At this point, thecontroller110 may extract the information with the highest priority among the plural items of information included in the content from thestorage unit175, as the representative information.
• For example, the calendar corresponding to the content may include the plural items of information corresponding to the month and year, the date, and the schedule. Further, the priorities corresponding to the month and year, the date, and the schedule that correspond to the plural items of information may be stored in thestorage unit175.

Accordingly, the representative information may be a month of the calendar with the highest priority. In addition, the priority may not be changed. Therefore, thecontroller110 may extract the month of the calendar with the highest priority among the plural items of information included in the calendar as the representative information. For example, April corresponding to the scrolled month of the calendar may be extracted as representative information of the calendar.
• Subsequently, the representative information of the content is displayed inoperation1050. Thecontroller110 may display the extracted representative information of the content on the display unit. At this point, the representative information may be displayed in a stopped manner. Accordingly, as described above, since the representative information is displayed in a stopped manner, the representative information may be easily recognized by the user, while it is difficult for the user to recognize the content due to the movement according to scrolling the content.
• For example, as illustrated inFIG. 6A, April corresponding to the month of the calendar which is extracted as representative information of the calendar may be displayed on thedisplay unit190. At this point, the April400 corresponding to the representative information may be displayed in awindow402 in a stopped manner. Accordingly, even if it is difficult to recognize what month the scrolled month corresponds to, due to scrolling the calendar, since the April400 corresponding to the representative information is displayed in a stopped manner, the user may easily recognize the scrolled month corresponds to April.
• Therefore, according to an exemplary embodiment of the present invention, when scrolling content, the user may instantly recognize what the currently scrolled content is about, by displaying the representative information of the content.
• Subsequently, scrolling the content is stopped inoperation1060. Thecontroller110 may stop scrolling the content. At this point, thecontroller110 enables the representative information to disappear. For example, as illustrated inFIG. 6B, thecontroller110 may stop scrolling the calendar corresponding to the content. That is, as illustrated inFIG. 6B, scrolling the calendar from the March204 to the April205 is stopped so that April is displayed on thedisplay unit190. At this point, as illustrated inFIG. 6B, the displayed “April” corresponding to the representative information may disappear. Further, aschedule209 for April 19 corresponding to the 19th day which is thedate206 of April is displayed as illustrated inFIG. 6B.

Further, the content may be photographs executed in a gallery application.FIGS. 7A and 7B, andFIGS. 8A and 8B are diagrams illustrating examples in which theelectronic apparatus100 is a mobile device, and the content is photographs executed in a gallery application. With reference toFIGS. 7A and 7B, andFIGS. 8A and 8B, thecontroller110 of the mobile device may display the content corresponding to the photographs executed in the gallery application on thedisplay unit190. Further, the display unit may be formed with thetouch screen190. Therefore, thecontroller110 may execute the gallery application, and display the photographs on thetouch screen190. With reference toFIG. 7A, aphotographs210 resulting from the execution of the gallery application are displayed on thetouch screen190. For example, thecontroller110 may display atitle212 of the gallery application and thephotographs210. At this point, thephotographs210 are orthogonally arranged with N rows and M columns in a grid form, and are displayed on thetouch screen190, as illustrated inFIGS. 7A to 8B. Further, thecontroller110 may display theschedule208 stored in thedate206.
• Subsequently, a gesture of scrolling the content is detected inoperation1020. Thecontroller110 may detect a gesture of scrolling the content. At this point, the gesture may be a drag or a flick with respect to the content on the touch screen forming the display unit. In addition, the gesture may be a drag or a flick of a scroll bar.
• For example, as illustrated inFIG. 7B, the gesture may be a drag or aflick310 with respect to the content on the touch screen. That is, thephotographs210 corresponding to the content may be displayed on thetouch screen190, as described above. At this point, the gesture may be the drag or theflick310 with respect to the photographs. For example, as illustrated inFIG. 7B, the gesture may be the drag or theflick310 with respect to the photographs in the left or right direction.
• Subsequently, if the gesture is detected, scrolling the content is started inoperation1030. If the gesture is detected, thecontroller110 may start to scroll the content.

At this point, the representative information may be fixed information. At this point, the fixed information refers to information of which the priority is fixed and does not change. Further, the fixed information may be a title, a tag, or a table of contents of the content.
• The plural items of information included in the content are stored in thestorage unit175. Further, thestorage unit175 may store priorities corresponding to the respective plural items of information. At this point, thecontroller110 may extract information with the highest priority among the plural items of information included in the content from thestorage unit175, as the representative information.
• For example, the photographs corresponding to the content may include the plurality items of information corresponding to images, photographers, captured dates, and tags. Further, priorities of the images, the photographers, the captured dates, and the tags corresponding to the plural items of information may be stored in thestorage unit175. The tags may be information attached to the image. For example, the tags may be names of events generated with respect to the photographs. For example, if the photographs are captured during a travel in Australia, the tags may be “Travel AU”. In addition, the representative information may be fixed information. Further, the fixed information may be tags of the content. Accordingly, the representative information may be a tag of the photograph with the highest priority. In addition, the priority may not change. Accordingly, thecontroller110 may extract the tag of the photograph with the highest priority among the plural items of information included in the photographs, as the representative information. For example, the “Travel AU” corresponding to the tags of the scrolled photographs may be extracted as the representative information of the photographs.
• Subsequently, the representative information of the content is displayed inoperation1050. Thecontroller110 may display the extracted representative information of the content on the display unit. At this point, the representative information may be displayed in a stopped manner. Accordingly, as described above, since the representative information is displayed in a stopped manner, the representative information may be easily recognized by the user, while it is difficult for the user to recognize the content due to the movement according to scrolling the content.
• For example, as illustrated inFIG. 8A, the ‘Travel AU’410 corresponding to the tags of the photograph extracted as the representative information of the photographs may be displayed in awindow412 on thedisplay unit190. At this point, the ‘Travel AU’410 corresponding to the representative information may be displayed in a stopped manner. Accordingly, even if it is difficult to recognize the scrolled photographs due to scrolling the photograph, the ‘Travel AU’410 corresponding to the representative information is displayed in a stopped manner, so that the user may easily recognize that the scrolled photographs correspond to photographs captured during the travel in Australia.
• Therefore, according to an exemplary embodiment of the present invention, when scrolling the content, the representative information of the content is displayed, so that the user may instantly recognize what the currently scrolled content is about.
• Subsequently, scrolling the content is stopped inoperation1060. Thecontroller110 may stop scrolling the content.

• However, as scrolling the content starts, it may be difficult for the user to recognize the content due to the movement according to scrolling. That is, due to the movement according to scrolling the content, it may be difficult for the user to recognize what content is being displayed. For example, as illustrated inFIG. 12A, due to the movement according to scrolling the list items, it may be difficult for the user to recognize what book page is being displayed.
• Subsequently, representative information of the content is extracted inoperation1040. Thecontroller110 may extract the representative information of the content. At this point, thecontroller110 may extract a list item with the highest priority among the plurality of list items included in the content, as the representative information. Further, the priority may be determined based on the number of views of the contents or the number of touch events. Further, thestorage unit175 may store the plurality of list items included in the content. Further, the priorities included in the respective list items may be stored in thestorage unit175. Accordingly, thecontroller110 may extract the list item with the highest priority among the plurality of list items included in the content from thestorage unit175, as the representative information.
• For example, as illustrated inFIG. 11A, thecontroller110 may display the plurality oflist items230 found by anInternet search engine232 on thedisplay unit190, as a list view. In addition, thecontroller110 may extract a list item with the highest priority among the plurality oflist items230 as the representative information. Further, the priority may be determined, for example, by the number of views of the content. For example, if the number of views of the list item corresponding toNews 20 is the largest, the priority of the list item corresponding toNews 20 may be determined to be the highest. Accordingly, thecontroller110 may extract the list item corresponding toNews 20, as representative information.
• Further, the representative information may be variable information. At this point, the variable information refers to information of which the priority can be changed. That is, the priority of the representative information can be changed, since the number of views of the content or the number of touch events can be consistently updated. For example, if the representative information is the number of views corresponding to the variable information, a list item that has the largest number of views may be changed depending on the update of the number of views. Accordingly, thecontroller110 may extract the representative information by charging the priority depending on the updated number of views.
• Subsequently, the representative information of the content is displayed inoperation1050. Thecontroller110 may display the extracted representative information of the content on the display unit. At this point, the representative information is displayed in a stopped manner. Accordingly, as described above, since the representative information is displayed in a stopped manner, the representative information may be easily recognized by the user, while it is difficult for the user to recognize the content due to the movement according to scrolling the content.
• For example, as illustrated inFIG. 12A, thecontroller110 may displayNews 20 corresponding to the list item extracted as the representative information as “News 20 title”430 in awindow432 on thedisplay unit190. At this point, the “News 20 title”430 corresponding to the representative information is displayed in a stopped manner. Accordingly, as the list items are scrolled, even if it is difficult to recognize the scrolled list items, since the “News 20 title”430 corresponding to the representative information is displayed in a stopped manner, it is possible to provide the user with the representative information among the currently scrolled list items. Accordingly, the user may recognize representative information with the largest number of views among the plurality of currently scrolled list items. Therefore, when scrolling the content, the user may recognize the representative information in addition to the scrolling function.
• Therefore, according to another exemplary embodiment of the present invention, when scrolling the list items corresponding to the content, it is possible to display and provide the representative information of the list items in addition to the scrolling function.
• Subsequently, scrolling the content is stopped inoperation1060. Thecontroller110 may stop scrolling the content.

Accordingly, thecontroller110 may load the priorities stored in thestorage unit175 and may extract a list item with the highest priority as representative information.
• For example, as illustrated inFIG. 13A, thecontroller110 may display the plurality oflist items240 displayed on thestock application242 on thedisplay unit190, as a list view. In addition, thecontroller110 may extract a list item with the highest priority among the plurality oflist items230, as the representative information. In addition, the priority may be determined by the user designation. For example, if the priority of a list item corresponding to Stock11 is designated to be the highest by the user, thecontroller110 may extract the list item corresponding to Stock11 as representative information.
• Subsequently, representative information of the content is displayed inoperation1050. Thecontroller110 may display the extracted representative information of the content on the display unit. At this point, the representative information is displayed in a stopped manner. As described above, since the representative information is displayed in a stopped manner, the representative information may be easily recognized by the user, while it is difficult for the user to recognize the content due to the movement according to scrolling the content.
• For example, as illustrated inFIG. 14A, thecontroller110 may displayStock11 corresponding to the list item extracted as the representative information in awindow442 on thedisplay unit190 as “Stock11: Samsung”440. At this point, the “Stock11: Samsung”440 corresponding to the representative information may be displayed in a stopped manner. Accordingly, as the list item is scrolled, even if it is difficult to recognize the scrolled list item, the “Stock11: Samsung”440 corresponding to the representative information is displayed in a stopped manner so that the representative information among the currently scrolled list items may be provided with the user. Accordingly, the user may recognize the representative information with the highest priority designated by the user among the currently scrolled list items. Accordingly, when scrolling the content, the user may recognize the representative information in addition to the scrolling function.
• Therefore, according to another exemplary embodiment of the present invention, when scrolling the list items corresponding to the content, it is possible to display and provide the representative information of the list items in addition to the scrolling function.
• Subsequently, scrolling the content is stopped inoperation1060. Thecontroller110 may stop scrolling the content. At this point, thecontroller110 may enable the displayed representative information to disappear. For example, as illustrated inFIG. 14B, thecontroller110 may stop scrolling the list items corresponding to the content. That is, as illustrated inFIG. 14B, scrolling list items to a list item corresponding to Stock33 stops and the list items to the list item corresponding to Stock33 are displayed on thedisplay unit190. At this point, as illustrated inFIG. 14B, the “Stock11: Samsung”440 corresponding to the displayed representative information may disappear.
