That is, the scroll bar 350 of the present invention applies one scroll bar without selecting another button to select another viewable object at a higher level or another viewable object at the same level, You can scroll viewable objects at different levels depending on the position and the moved position of the slider.

Meanwhile, in the embodiment of the present invention, in order to scroll a viewable object of a specific item, that is, a lower level (level 4 in FIG. 2C), as a child element of the viewable object while scrolling a viewable object at a higher level, Selecting the item when the item is focused, or placing the position of the slider in the area where the viewable object of the current level is displayed. For example, the user can perform the selection of the item by dragging the slider.

Hereinafter, the operation using the user interface of the present invention will be described.

3A and 3B are views showing a schematic configuration of a scroll bar and an operation example thereof according to an embodiment of the present invention.

First, the shape of the scroll bar 350 of the present invention is configured to distinguish each level according to the multilevel. In addition, feedback information such as a vibration and an audio signal is generated with respect to a point where the level dividing line is covered by the user's hand or the like when the touch screen is operated, or the feedback information such as vibration and audio signal is generated through movement of the first hole 370 including the slider 360 So that it can notify the time when it crosses the dividing line. This will be described with reference to FIGS. 3A to 3B.

Referring to FIG. 3A, an example of the scroll bar 350 shown in FIG. 3A is an example of a form of a scroll bar capable of browsing two levels of levels. 3A, the section A is a scroll section of the viewable object currently displayed on the screen, and can be scrolled and browsed corresponding to the movement of the slider 360 in the scroll area. Section B shows an example in which the first hole 370 including the slider 360 is moved when the slider 360 is out of a preset limit. At this time, when the slider 360 is out of a specific section as in the B section, it can be switched to the upper level of the viewable object to scroll and browse. This will be described in detail with reference to FIG. 3B.

Referring to FIG. 3B, when the touch screen or the touch pad is used instead of the actual physical key, it may be difficult for the user to physically confirm the moment passing the level change section. Accordingly, when the user exceeds the set scroll level, the slider 360 is stopped by the section C. If the user further pulls the slider 360, the user moves the slider 360 to the finger contact point instantaneously. At this time, Signal, etc.) may be given to notify that the level interval has changed.

In addition, since the finger may clog the slider 360 in the case of an actual touch screen, it is difficult to visually recognize the pause in the C section. Thus, by allowing the first hole 370 of the scroll area including the slider 360 in the section D to perform an operation such as moving or pausing corresponding to the slider 360, the user visually changes the level You can check the section.

4A to 4D are views illustrating a user interface and operation according to an embodiment of the present invention.

4A to 4D are diagrams illustrating a scroll operation for a viewable object at a current level. That is, FIGS. 4A to 4D show the scroll operation for the viewable object currently displayed on the window.

4A to 4D, the position of the slider 360 in FIG. 4A may be located at the center of the first hole 370. FIG. When the user stops the control of the slider 360 (e.g., an operation such as releasing the hand after touching and dragging the slider 360) after the operation according to a user request, the slider 360 returns to the center position Home position).

4B to 4C, the scroll speed of the viewable object according to the movement of the slider 360 may be proportional to the distance moved by the user from the center portion. The control of such a slider 360 can be operated according to a user's control on an actual controller, a touch pad, or a touch screen.

The user can adjust the scrolling speed of the user arbitrarily starting from the initial position of the slider 360 (the middle portion of the first hole 370). That is, the scrollable object can be scrolled at a speed corresponding to the moving speed of the slider 360 by the user.

As shown in FIGS. 4B to 4C, when the slider 360 is downwardly moved by touching and dragging, the viewable object on the screen is scrolled up and the contents of the lower portion of the viewable object are displayed. At this time, the scroll speed of the viewable object may be proportional to the distance of the slider from the initial position of FIG. 4A.

4D, if it is assumed that the slider 360 is within the allowable range of the first hole 370 and the scroll of the viewable object is not completed, The scrolling operation can be performed at a preset maximum speed when reaching the end of the first hole 370. If the slider 360 is out of the range of the scroll region 320, the scroll operation may be performed according to the level change. 5 (a) to 5 (d).

5A to 5D are diagrams illustrating a user interface and operation according to an embodiment of the present invention.

5A to 5D illustrate an operation of switching to a viewable object at a higher level than the viewable object displayed on the window and scrolling the viewable object.

5A and 5B, when the slider 360 is out of the scrollable range of the currently displayed viewable object as shown in FIGS. 5A and 5B, the upper level of the viewable object is changed, The menu list corresponding to the level of the menu which is the parent element of the object can be displayed. For example, when the slider is out of the allowable range, the viewable object, which is a child element of 'Anya' in FIG. 5A, is changed from the current level of the viewable object to a higher level during scrolling, A list of menus (Beatles, Cranberries, etc.) existing on the same level as the level of the menu can be displayed. At this time, it is possible to output the visual, tactile, and auditory feedback information defined by the user when the slider 360 is out of the allowable range.

If the user continuously scrolls the slider 360 beyond the limit range and scrolls to the last content of the viewable object, the next viewable object having the same level as the viewable object (e.g., 'Beatles' Is continuously displayed, and it is possible to continuously perform scrolling on the next viewable object. That is, other viewable objects that are on the same level as the upper level menu (e.g., Anya) to which the currently displayed viewable object belongs and that are child elements of the menu (e.g., Beatles) . That is, the viewable object that is on the same level as the viewable object of the current level but belongs to another group can be continuously scrolled.

5B and 5D, when the slider 360 is out of the limit of the first hop 370 even after the user receives the feedback information, the upper level of the viewable object (E.g., Anya) corresponding to the menu and a list of other menus (Beatles, Cranberries, etc.) existing on the same level as the menu. At this time, the switching and display of the upper level may be displayed while gradually covering the lower-level viewable object displayed previously as shown in FIG. 5B.

As shown in FIGS. 5C and 5D, when the menus of the completely upper level completely form the normal list of the general form, they are scrolled at a preset minimum speed. When the user continuously moves the slider 360 down in the high level scroll operation, the menus of the upper level constituting the menu list are scrolled up and other menus on the lower side are displayed in the screen.

6 is a diagram illustrating an operation for directly entering a higher level using a user interface according to an embodiment of the present invention.

Referring to FIG. 6, when an attempt is made to directly enter the upper level of the viewable object displayed on the current screen, an input event (touch or tab, etc.) is displayed on any one of the upper and lower switching areas 380 So that it is possible to switch directly to the higher level.

For example, as shown in FIG. 6, when the upper switching region 380 is touched, a list of menus existing on the same level as the menu corresponding to the upper level of the current level (e.g., Anya) is displayed. At this time, the menus of the list may be displayed in the order of the set order.

When the complete menu list is formed, the menu list of the upper level can be scrolled. At this time, since the scroll is not a scrolling operation by the slider 360, an acceleration according to the input event occurrence time (e.g., a touch time) may be applied instead of the scroll speed by the slider 360. [

7A to 7G are views illustrating an example in which a multi-level scroll bar according to an embodiment of the present invention is applied to an application program.

Particularly, the embodiments of FIGS. 7A to 7G show a case where the scroll bar of the present invention is applied during music playback using a music playback application program.

7A to 7G, if the application program supports a multilevel scroll bar, the scroll bar of the present invention may be displayed as a viewable object (a specific music file playback status screen) together with the application program and execution, Lt; / RTI > Particularly, Figs. 7A to 7G show an example in which the scroll bar of the present invention is a horizontal scroll bar.

Next, in the period of FIG. 7B and FIG. 7C, in response to the movement of the slider 360, the music file is moved to a specified time area of the music file track in progress. This corresponds to the function of forward and backward, and the speed of the forward / backward word can be adjusted in proportion to the moving distance of the slider 360.

Next, when the slider 360 is moved to the area of FIG. 7D, that is, when the slider 360 reaches the limit of the first hole 370 and the user continuously scrolls, Similarly, playback of the next music file on the same level as the current music file level can be performed immediately.

Alternatively, when scrolling is continued in the area of FIG. 7D, a list of music files of child elements corresponding to the same level as the current music file and designated as a group in the upper level menu, which is the parent element of the current music file, Can be displayed and scrolled. That is, as shown in FIGS. 7D and 7E, a list of music files belonging to a high level menu (for example, Abba) of the current music file is displayed while being scrolled.

7E, when the slider 360 moves away from the limit of the first hole 370, the slider 360 is moved to a position corresponding to the upper section scroll do. Thus, a list of menus existing on the same level as the high level menu of the current music file is displayed. In addition, in response to the scrolling of the slider 360, the list of menus is scrolled as shown in FIGS.

Meanwhile, in FIGS. 3A to 7G, a scroll bar browsing the two-step level of the present invention has been described. However, the present invention may include a scroll bar capable of three levels of browsing, as shown in FIG. 2C or FIG. 8, for example. At this time, it is preferable to apply the scroll bar of three or more stages to a larger device.

FIG. 8 is a diagram illustrating an application example of a user interface according to the embodiment of FIGS. 7A to 7G.

8, the scroll bar of the present invention is applied to a music playback application program as in the embodiments of FIGS. 7A to 7E. In particular, FIG. 8 illustrates an example in which a progress bar provided in the music playback application program is combined with the scroll bar to browse three levels.

Referring to FIG. 8, the slider 360 of the present invention may include a progress bar 365. Thus, the forward / backward word of the currently playing music file can be controlled by the progress bar 365.

First, when the progress bar 365 reaches the set range within the slider 360, as indicated by reference characters A and B, as described above, It is possible to reproduce another music file or to display and scroll the list of music files existing on the same level. Also, as shown in C, when the progress bar 365 moves out of the set limit range of the slider 360, the list display of the menus existing on the same level as the next level menu of the current music file, Can be performed.

Next, when the slider 360 moves to reach the limit range of the first hole 370 as shown by reference symbol D, a list of menus existing on the same level as the upper level menu of the next higher level menu Display and scroll can be performed.

As shown in FIG. 8, by controlling the forward / backward word of the current music file using a progress bar in the application program, it is possible to control the upper level or the index list.

Meanwhile, the scroll bar of three or more stages according to the embodiment of the present invention may operate the control operation only in one linear direction, or may be divided into upper, lower, left, and right operations.

9 is a diagram illustrating an example of another structure for controlling a scroll bar according to an embodiment of the present invention.

First, the control using the scroll bar of the present invention allows the user to directly control the scroll bar on the touch screen through an input event. 9, the user may control the operation of the scroll bar by the touch pad 400 formed on the input unit or the like corresponding to the scroll bar.

In addition, the control of the scroll bar may be controlled by applying it to a physical key, or a virtual key corresponding to the scroll bar may be indirectly controlled by mapping to a navigation key or the like.

10A and 10B are views illustrating a method of browsing a menu of a tree structure using a user interface according to an embodiment of the present invention.

10A and 10B, the controller of the portable terminal displays an arbitrary viewable object according to a user request (step 1001), and can check whether an event is generated (step 1003). The event includes an input event as described above, and FIGS. 10A and 10B illustrate a case where the event is a search event occurring in a scroll bar.

As a result of the check, if an event occurs in the scroll bar, the controller determines the occurrence position of the event (step 1005). That is, the controller may determine whether the event occurs in a scroll region of the scroll bar or in a scroll region of the scroll bar.

At this time, if the event is an event occurring in the switching area (operation 1007), the controller may switch to a higher level corresponding to the event occurrence location and display the corresponding viewable object (operation 1009). For example, in response to the event, the upper level menu of the viewable object displayed on the current screen is entered, and a list of menus existing on the same level as the upper level menu can be displayed. Thereafter, the controller may proceed to step 1035 described below. At this time, the user can control the level switching by touching or tabping the switching area.

If the event is an event that controls the movement of the slider in the scroll area (operation 1007), the controller processes the scroll operation of the viewable object in response to the movement of the slider. In addition, the controller checks the scroll level according to the movement of the slider (Step 1011). At this time, the user can control the movement of the slider by a touch & drag operation.

Next, the controller determines whether the tm crawl level reaches a predetermined threshold (step 1013). If the scroll level does not reach the limit, the controller proceeds to step 1023 to continue the scroll operation of the viewable object in response to the slider control.

On the other hand, if the scroll level reaches the limit range, the scroll operation of the viewable object can be controlled corresponding to the scroll level (Step 1015). For example, at the scroll level of the limit range, the scroll speed of the viewable object can be increased.

Next, the controller can check whether there is a level change request during the scroll of the viewable object (step 1017). That is, it can be determined whether there is a request to switch to a higher level than the level of the current viewable object. In step 1017, the level change request determination may determine whether an event occurs in the scroll region of the scroll bar or whether the slider is out of the limit range. In the following description, step 1017 is a step of checking whether or not an event of the switching area is generated.

If the level change request is detected (step 1017), the control unit determines that it is a higher level entry (step 1019), switches to the corresponding upper level according to the level change request, and displays the viewable object corresponding to the higher level (Step 1021). Then, the controller displays the viewable object according to the switching, scrolls the viewable object at the higher level in response to a user request, outputs a viewable object according to a specific item selection of the viewable object, And processing the corresponding operation according to whether or not it is possible.

Next, in operation 1023, the controller may scroll the viewable object and display the corresponding display in response to the slider control of the user in step 1027. In step 1023,

Next, the controller may check whether the contents of the viewable object reach the last time during the scroll (Step 1025). For example, if the viewable object is a specific document composed of text, it can check whether the last line of the last page of the document is reached. In addition, when the viewable object is a music file, it is possible to check whether play of the music file is ended.

Next, if the content of the viewable object is not the last, the controller may proceed to step 1017 and repeat the above process. On the other hand, if the control unit detects that the content of the viewable object has reached the last time, it can determine whether there is a level change request corresponding thereto in step 1027. In step 1027, the level change request determination may determine whether an event occurs in the scroll region of the scroll bar or whether the slider is out of the limit range. In the following description, step 1027 is a step of determining whether or not the slider is out of the limit range.

If the level change request is not received, the controller proceeds to step 1037 and performs a corresponding operation according to a user request. On the other hand, if there is a level change request, the control unit can output feedback information to the user (Step 1028). That is, the control unit may provide feedback information, such as outputting a vibration or outputting a set audio signal, in order to notify the user that level switching is performed at a time point when the slider deviates from the preset limit range.

At this time, the controller may output the feedback information while stopping the slider in the limit range when the level change occurs. Thereafter, when the control of the slider beyond the limit range is continuously performed by the user even after the output of the feedback information, the controller may cause the slider to momentarily move to the point where the user's event occurs.

Next, if there is a level change request continuously after outputting the feedback information, the controller can check whether there is a next viewable object existing on the same level as the current level of the currently displayed viewable object (Step 1029 ).

If there is no next viewable object on the same level, the control unit switches to a higher level to which the viewable object belongs and displays a list of menus that exist on the same level as the higher level menu and the higher level menu (Step 1033).

On the other hand, if there is a next viewable object on the same level, the controller can extract the contents of the next viewable object and display the contents of the other viewable object on the screen (Step 1031). The control unit may process the scroll of the next viewable object according to the control of the slider of the user, and may perform an operation corresponding to the steps described above.

Next, the controller may check whether the event is ended during the scroll control described above (step 1035). That is, the controller can check whether the operation such as the scroll control according to the user request is ended as described above. Such a termination may be an end of event input by the user, and may be a request to end display of the viewable object, an end of the scroll control operation according to the execution of the function of the specific viewable object, and the like. At this time, when the event ends, the control unit may terminate the above-described procedure, and if the event is not terminated, the corresponding operation corresponding to the scroll bar control of the present invention as described above may be performed (Step 1037) .
