For example, the first operation unit 131 receives commands such as start, end, scroll, and the like, and the second operation unit 132 controls the size of the sound output from the sound output unit 152 or the size of the sound output from the display unit 151 To the touch recognition mode of the touch screen.

Front touch

Hereinafter, the operation of the display unit 151 and the touch pad 135 will be described with reference to FIG. 3.

3 is a front view of a portable terminal for explaining an operation state of the portable terminal according to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be referred to as a so-called " virtual keypad ".

3 illustrates inputting of a touch applied to the virtual keypad through the front surface of the terminal body.

The display unit 151 may operate in an entire area or may be operated in a divided manner. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. The output window 151a and the input window 151b are areas allocated for outputting or inputting information, respectively. In the input window 151b, a virtual keypad 151c is displayed in which a number for inputting a telephone number or the like is displayed. When the virtual keypad 151c is touched, numbers and the like corresponding to the touched virtual keypad are displayed on the output window 151a. When the first operation unit 131 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This may be useful for editing an image displayed on the display unit 151.

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be activation or deactivation of the display unit 151 or the touch pad 135, for example.

Proximity touch

The proximity sensor 141 described with reference to FIG. 1 will be described in more detail with reference to FIG. 4.

4 is a conceptual diagram illustrating a proximity depth of a proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger or pen approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen detects this and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a distance between the proximity touched pointer and the touch screen (hereinafter, referred to as “proximity depth”).

In FIG. 4, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a touch touch. When the pointer is positioned below the distance d ₁ on the touch screen, the pointer is recognized as a proximity touch of a first proximity depth. When the pointer is spaced apart from the distance d ₁ or more and less than d ₂ on the touch screen, the pointer is recognized as a proximity touch of a second proximity depth. When the pointer is spaced apart from the distance d ₂ or more and less than d ₃ on the touch screen, the pointer is recognized as a proximity touch of a third proximity depth. When the pointer is positioned at a distance of more than d ₃ from the touch screen, the proximity touch is recognized as released.

Accordingly, the controller 180 may recognize the proximity touch as various input signals according to the proximity depth and the proximity position of the pointer, and perform various operation control according to the various input signals.

Meanwhile, a graphic in the form of an arrow or a finger for pointing a specific object or selecting a menu on the display unit is called a pointer or a cursor. However, in the case of a pointer, it often means a finger or a stylus pen for a touch operation or the like. Therefore, in this specification, a graphic displayed on the display unit is referred to as a cursor, and a physical means for performing a touch, a proximity touch, and a gesture, such as a finger or a stylus pen, is referred to as a pointer.

First, the first stereoscopic image category will be described.

The first category is a method in which the same image is provided in both eyes (monoscopic), which can be implemented as a general display unit. More specifically, the controller 180 arranges a polyhedron generated through one or more points, lines, planes, or a combination thereof in a virtual three-dimensional space, and displays an image viewed from a specific viewpoint on the display unit 151. That's how. Therefore, the substantial part of such a stereoscopic image can be referred to as a planar image.

The second category is a stereo scopic method in which different images are provided in both eyes. It is a method using a principle of feeling a three-dimensional feeling when a human is looking at an object with the naked eye. That is, two eyes of a person see different plane images when viewing the same object by the distance between them. These different planar images are transmitted to the brain through the retina, and the brain fuses them to feel the depth and reality of the stereoscopic image. Therefore, binocular disparity due to the distance between the two eyes makes a sense of stereoscopic effect, and this binocular disparity becomes the most important element of the second category. Such binocular disparity will be described in more detail with reference to FIG. 5.

5 is a conceptual diagram for explaining the principle of binocular disparity.

In FIG. 5, it is assumed that the hexahedron 510 is visually placed in front of the eye level. In this case, the left eye planar image 520 showing only three surfaces of the top, front, and left sides of the hexahedron 510 is seen as the left eye. In addition, as the right eye, the right eye plane image 530 showing only three surfaces of the top, front, and right sides of the cube 510 is visible.

If the left eye plane image 520 is reached in the left eye and the right eye plane image 530 is reached in the right eye, even if the object is not an object in front of the eye, the person may feel as if the user actually sees the cube 510.

As a result, in order to implement the stereoscopic image of the second category in the mobile terminal, the left eye image and the right eye image, which have been viewed with the same object at a predetermined time, must be separated and reached through the display unit.

In the present specification, in order to distinguish the above two categories, for convenience, a stereoscopic image of the first category is referred to as a "2D stereoscopic image", and a stereoscopic image of the second category is referred to as a "3D stereoscopic image".

Next, an implementation method of the 3D stereoscopic image will be described.

As described above, in order to realize a 3D stereoscopic image, it is necessary that the right eye image and the left eye image are divided into two and reach the binocular. Various methods for this are described below.

1) parallax barrier method

The parallax barrier method is a method of controlling a light propagation direction by electronically driving a blocking device provided between a general display unit and both eyes so that different images may be reached in both eyes.

The structure of the view barrier type display unit 151 for displaying a 3D stereoscopic image may have a configuration in which a switch liquid crystal is combined on an upper portion of a general display device. By operating the optical parallax barrier provided in the switch liquid crystal it is possible to control the direction of the light to be separated so that different light reaches the left and right eyes. Therefore, when a combined image of the right eye image and the left eye image is displayed on the display device, the user's point of view of the image corresponding to each eye is felt as if displayed in three dimensions.

In addition, by controlling the parallax barrier electrically so that all the light is transmitted, separation of the light by the parallax barrier can be eliminated so that the same image can be seen by the left and right eyes. In this case, the same function as that of the general display unit may be performed.

On the other hand, a parallax barrier generally provides a 3D stereoscopic image based on one axis, but a parallax barrier capable of parallel movement in two or more axial directions according to a control signal of the controller 180 may be used.

2) Lens refraction method

The lens refraction method (lenticular) is a method using a lenticular screen provided between a display part and a binocular eye, and a method of refracting a traveling direction of light through lenses on a lenticular screen so that different images are reached in both eyes.

3) polarized glasses system

Polarized light is polarized so that the directions of polarization are orthogonal to each other to provide different images in both directions or in the case of the circular polarized light so that the directions of rotation are different from each other.

4) Active shutter method

As a type of glasses, the right eye image and the left eye image are alternately displayed at predetermined intervals through the display unit, and the user's glasses close the shutter in the opposite direction when the image in the corresponding direction is displayed, and the image in the corresponding direction is displayed in the corresponding direction. How to reach the eye. That is, the left eye image only reaches the left eye while the left eye image is displayed, and the left eye image reaches only the left eye while the right eye image is displayed.

For convenience of description, it is assumed that the mobile terminal mentioned below includes at least one of the components shown in FIG. 1. In particular, the mobile terminal to which the present invention is applicable includes a display unit capable of providing a 3D stereoscopic image to a user through at least one of the aforementioned 3D stereoscopic image implementation methods.

A mobile terminal according to an embodiment of the present invention may provide a stereoscopic user interface using a plurality of layers having different 3D depths in a virtual stereoscopic space.

First, a layer structure applied to embodiments of the present invention will be described with reference to FIG. 6.

6A to 6C each show an example of a layer arrangement structure applied to embodiments of the present invention.

Although the following display state diagrams including FIG. 6 are shown as planar images due to the limitation of the drawing, it is assumed that they represent stereoscopic images provided to the user in the above-described 3D stereoscopic image implementation.

First, referring to FIG. 6A, a total of three layers from layer 1 to layer 3 may be arranged in a stacked form at a predetermined interval in a virtual three-dimensional space. When the layers are implemented as 3D stereoscopic images through the display unit 151, the layer 1 is at the top of the user and has a low 3D depth so that the user feels close to the user. In addition, as layer 3 goes through layer 2, the height of placement gradually decreases, and deep 3D depth is felt to be far from the user.

In this layer structure, each layer may have a predetermined transparency. For example, if all layers are set to be translucent, the user can see the surface of each layer from layer 1 to layer 3. If only layer 2 is opaque, the user may see only the surface of layer 2 by passing through the surface of translucent layer 1 and translucent layer 1 and may not see layer 3.

Also, the layers may be changed in position and / or 3D depth through a predetermined command input through the user input unit. The command input for manipulating the layers may include a camera 121 for photographing the location of the pointer, a proximity sensor 140 for recognizing the proximity distance of the pointer, and a touch screen 151 for recognizing the contact touch and the proximity touch. Or the like). The case where the arrangement position of the layer is changed will be described with reference to FIGS. 6B and 6C.

6B and 6C, only layer 1 and layer 2 exist, and layer 2 is assumed to have three sub-layers 610, 620, and 630 having the same size as layer 1 connected in a horizontal direction. In addition, it is assumed that layer 1 is transparent or translucent.

Referring to FIG. 6B, the layer 1 is a size corresponding to the entire screen on the display unit, and the sublayer 610 positioned in the middle of the layer 2 is visible through the layer 1 on the display unit at the user's viewpoint 650. . That is, the left sublayer 620 and the right sublayer 630 remain in the form of layer 2 in the virtual space. However, only the central sublayer 610 is displayed on the display unit.

In this case, the user may apply a predetermined input to change the arrangement state of the layer 2, that is, the area displayed on the display unit. For example, when the display unit is a touch screen and only the layer 2 can be moved in parallel through dragging or flicking (that is, a touch pattern inputted by touching a pointer in one direction and then flipping), the user may move to the left side. The flicking touch may be input in the direction so that the right sublayer 630 is displayed on the touch screen as shown in FIG. 6C. At this time, depending on the input for moving layer 2 in parallel (i.e. scrolling) (i.e., depending on the duration or input distance of dragging or flicking), layer 2 may move continuously, The sublayers may be moved in units of sublayers so that the sublayers are displayed. In the case of continuous movement, a portion of the right side of the center sublayer 610 and a portion of the left side of the right sublayer 630 may be simultaneously displayed on the display unit.

In addition, when an arbitrary layer is larger than the size corresponding to the entire screen of the display unit, the layer may not exist as a sublayer but exist as one layer.

In addition, the arrangement of the above-described sublayer is an example and the present invention is not limited thereto and may be applied to various sublayer arrangements. For example, each sublayer may be connected in a vertical direction or in a lattice form in the horizontal and vertical directions. Further, in the same layer, the sublayers may be spaced apart from each other by a predetermined interval without being connected in contact with each other.

In addition, the above-described sublayer may be an area including a preset number of icons, an area set by a user on an application execution screen, an area set by an application, or an area corresponding to one page of a document. The unit may be set to a size that can be displayed on one screen.

One or more icons may be disposed on each of the above-described layers. Here, one icon may represent one file or may perform a shortcut function for a specific file, an application, or a menu. In a stereoscopic user interface including a plurality of layers, a user frequently changes or positions such an icon, and thus a method for more conveniently performing the same is required.

Therefore, in the present embodiment, the 3D depth of the icon is changed in order to change the position or copy the icon located on an arbitrary layer (or sublayer), that is, move to a layer having a different 3D depth. Suggest a way to perform location changes. When this method is applied, the user can change the area displayed on the display unit from the existing layer and return the icon to the existing layer while moving the icon from one layer to another layer. It is convenient. This will be described with reference to FIG. 7.

7 is a flowchart illustrating an example of a method of changing a position of an icon according to an embodiment of the present invention.

In the present embodiment including FIG. 7, it is assumed that a stereoscopic 3D stereoscopic image is provided to a user through a display unit, and there are a plurality of layers including a layer having a reference 3D depth as a reference of the 3D depth. In addition, it is assumed that at least one icon exists in the layer having the reference 3D depth, and the layers except the layer having the reference 3D depth do not completely cover the layer having the reference 3D depth (ie, transparent or translucent).

Referring to FIG. 7, at least one icon may be selected as a predetermined command input through the user input unit 130 in a layer having a reference 3D depth (hereinafter, referred to as a “first layer” for convenience) among a plurality of layers. . In this case, when the display unit 151 is configured as a touch screen, a command for selecting an icon may be a touch input of a specific type such as long touch or multi touch (S701).

If the icon is selected by the user, the 3D depth of the selected icon may be changed to a 3D depth different from the first layer (S702).

Here, the change in the 3D depth of the selected icon may be regarded as the movement of the selected icon to the second layer having a different 3D depth than the first layer. In other words, when the icon moves each layer, it may mean that the icon is given the same 3D depth as the moved layer. The position where the moved icon is placed on the second layer is preferably a point corresponding to the point disposed on the first layer (ie, the same position when the user views through the display unit, but the 3D depth is changed). The selected icon may be arranged at a preset position in the second layer.

In this case, the 3D depth (ie, 3D depth of the second layer) given to the selected icon is preferably lower than that of the first layer (ie, to be closer to the user). In addition, the selected icon may be additionally provided with a predetermined visual effect such as vibration, shaking, color change, or size change.

In addition, the icon may be separated from the first layer and moved to the second layer according to a touch type for selecting an icon, or may be additionally generated in the second layer while the icon remains in the first layer. In the former case, it can be seen that the icon is moved, and in the latter case, the icon is copied.

If the 3D depth applied to the icon selected from the user is changed, the user may move the selected icon and / or the first layer (S703).

The user may change the position of the icon on the second layer while maintaining a touch input for selecting the icon to move the icon. After the touch input for selecting the icon is released, the icon may be started on the second layer through the proximity touch (or the proximity touch after first selecting the icon through the proximity long touch). In this case, the user may change (ie, scroll) an area of the first layer displayed on the display unit through a touch touch (for example, dragging or flicking) instead of the proximity touch.

If a touch touch input is not applied to the icon moved to the second layer, an area of the first layer displayed on the display unit may be changed through a touch input input on the touch screen.

When the manipulation of the selected icon or the first layer (that is, the position change or the display area change) is completed, the user may restore the icon to the 3D depth of the existing first layer (S704). To this end, the user may apply a predetermined menu manipulation or touch input through the user input unit 130 or may allow a specific operation to be recognized by the sensing module 140. When the sensing module 140 is used, the user may position the selected icon to a reference 3D depth by shaking or tilting the mobile terminal.

Hereinafter, a method of moving an icon described with reference to FIG. 7 will be described with more specific examples.

8 illustrates an example in which a layer and an icon are disposed according to an embodiment of the present invention.

The following figures, including FIG. 8, conceptually illustrate a stereoscopic user interface including a plurality of layers. Such a stereoscopic user interface may be provided to a user through a display unit as a 3D stereoscopic image through a stereoscopic method.

Referring to FIG. 8, a layer having a reference 3D depth (ie, a first layer: layer1) is disposed in a form in which three regions, that is, sublayers 810, 820, and 830 are horizontally connected, and a total of six icons. There is a second layer (layer2) arranged in this predetermined shape and having a lower 3D depth than the first layer. At this time, it is assumed that the second layer itself is transparent. That is, it is assumed that the second layer is virtually preset to represent 3D depth, and is not visible to the user. In addition, it is assumed that the size of one sublayer of layer 1 and the area corresponding to layer 2 are displayed through the display unit. That is, when a user views the display unit, it is assumed that an arrangement state in which the intermediate sublayer 810 of the first layer is visible through the transparent second layer.

In this case, the first layer may be a main menu screen or an execution region of an application that provides an image in which files and the like are arranged in the form of icons, such as a file explorer.

Hereinafter, specific methods for moving an icon in the stereoscopic user interface structure as shown in FIG. 8 will be described. In the following drawings including FIG. 9, parts of the first layer except for an area currently displayed on the display unit may be partially omitted.

In the following embodiments including FIG. 9, it is assumed that the display unit is configured as a touch screen.

9A to 9E illustrate an example of a method of moving an icon by changing a layer display area of a reference 3D depth according to an embodiment of the present invention.

First, referring to FIG. 9A, a user inputs a touch input (eg, a long touch) to select a corresponding icon using the pointer 920 to move the message icon 910 of the first layer to the bottom of the phone icon. Can be added.

Accordingly, the message icon 910 may be moved to the second layer (that is, changed to the 3D depth corresponding to the second layer) as shown in FIG. 9B.

Thereafter, the user may apply a drag (or flicking) touch 930 input to the first layer through the pointer 920 to move the first layer to the left as shown in FIG. 9C. Accordingly, as shown in FIG. 9D, the icons except for the message icon 910 are moved to the left as shown in FIG. 9D, and a circular icon 950 located in the right sublayer of the first layer may be displayed.

When the user wants to move a message icon other than the first layer on the second layer, a proximity touch on the message icon may be used.

When the first layer is moved as much as desired, the user inputs a command for moving the message icon 910 back to the first layer (for example, when the sensing unit 140 is used, shaking the mobile terminal or applying a message on the message icon). Losing long touch, etc.).

Accordingly, as illustrated in FIG. 9E, the message icon 910 may be moved back to the first layer. In detail, when a command for moving the selected icon from the second layer to the first layer is input, the icon may be moved to a point on the first layer corresponding to the point located in the second layer. In other words, the user is shown that the icon is vertically down. If another icon exists in a position where the corresponding icon is to be vertically lowered, an empty space is made by automatically changing the position of another existing icon to another point, and the icon may be moved in the created space. Alternatively, the icon moved from the second layer may be automatically moved to an empty space on the first layer.

With the method described above with reference to FIG. 9, the user can freely change the area of the first layer displayed on the display unit while moving the icon to change the position arranged on the first layer to the second layer. It is convenient to move from to back to the first layer.

In FIG. 9, the 3D depth of the selected icon is lowered, but the 3D depth of the icons except for the selected icon may be deeper. This will be described with reference to FIG. 10.

10A to 10E illustrate an example of an icon moving method by changing an icon position of a reference 3D depth in a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 10A, a second layer is positioned at a reference 3D depth, and four kinds of icons are arranged in a predetermined shape on the second layer. Also, a first layer provided with a 3D depth deeper than the second layer is located. In addition, it is preferable that the layer 2 is transparent or semitransparent so that an icon moving to the layer 1 can be seen.

In this case, the user may apply a long touch input to the icon 1010 with the pointer 1020 to move the message icon 1010.

Accordingly, as shown in FIG. 10C, icons except for the message icon 1010 may move to the first layer. In this case, the user may feel that icons except for the message icon are away from the user.

Thereafter, as shown in FIG. 10D, the user moves the message icon 1010 to a desired position by using the pointer 1020 and then sends a command (for example, shaking the mobile terminal) to reposition the icons except for the message icon 1010. Input can finish changing the icon position as shown in Figure 10e.

If an icon other than the selected icon is moved to the first layer, a touch input applied to the touch screen is not applied to the selected icon, but may be changed to change the display area of the first layer. In this case, the position of the selected icon on the second layer may be changed through the proximity touch input. This will be described with reference to FIGS. 10F to 10I.

10F to 10I illustrate an example of an icon moving method by changing a layer position in a mobile terminal according to an embodiment of the present invention.

First, referring to FIG. 10F, the basic layer structure is similar to that of FIG. 10A, but sublayer 1 1050 and sublayer 2 1060 exist in the second layer. In this case, four icons are disposed in sublayer 1 1050 and two icons are disposed in sublayer 2 1060. The sublayer 2 1060 is spaced apart from the right side of the sublayer 1 1050, and it is assumed that an area corresponding to the first layer and an upper virtual space thereof is displayed through the display unit. It is also assumed that the first layer itself is independent of transparency, but the second layer itself is transparent or translucent. Accordingly, in the situation of FIG. 10F, the user views the sublayer 1 through the display unit.

As the message icon 1010 is selected in FIG. 10F as shown in FIG. 10F, all icons except the message icon 1010 are moved to the first layer in the second layer. At this time, only three icons except for the message icon are shown away from the icons disposed on the sublayer 1 1050, but the icons of the sublayer 2 1060 also move to the layer 1 in the virtual space.

In this case, as described above, the touch input applied to the touch screen after the icon except for the selected icon 1010 is moved to the first layer is not applied to the selected icon 1010 and is displayed on the display unit. This is the input for movement.

Therefore, as the user applies a dragging or flicking touch input to the left through the touch screen, the icons located in the first layer move together to the left as shown in FIG. 10H. Accordingly, the two icons arranged in the sublayer 2 1060 appear to have a deeper 3D depth than the message icon on the display unit, and the three icons shown below the message icon in FIG. 10G are not visible.

Thereafter, the user may finish changing the icon position as shown in FIG. 10I by inputting a command (eg, shaking the mobile terminal) to reposition the icons except for the message icon 1010.

Meanwhile, according to another aspect of the present embodiment, a plurality of icons may be selected from a layer having a reference 3D depth.

Hereinafter, a method of selecting a plurality of icons will be described with reference to FIGS. 11 to 12.

11A to 11C each show an example of a form of selecting a plurality of icons in a multi-touch manner according to another aspect of an embodiment of the present invention.

In FIG. 11, the stereoscopic user interface structure of FIG. 8 is assumed.

First, referring to FIG. 11A, a user may multi-touch an icon located between two touch points by using two pointers 1110 and 1120 to generate two touch points with the display unit. When the user wants to select a plurality of icons, multi-touch may be sequentially applied to each icon. When the method is applied, the touch input for selecting the icon in the first layer is distinguished from the touch input for moving the icon moved to the second layer on the second layer.

Also, as illustrated in FIG. 11B, a plurality of icons may be selected at one time through multi-touch. That is, all of the icons located in the space 1130 between the two pointers 1110 and 1120 may be selected at once. The result is shown in FIG. 11C.

12A to 12C each show an example of a form of selecting a plurality of icons according to another aspect of an embodiment of the present invention by a menu manipulation method.

In FIG. 12, the basic stereoscopic user interface structure is assumed to be similar to that of FIG. 8.

Referring first to FIG. 12A, a menu area is provided at one edge of a first layer that is given a reference 3D depth and includes a plurality of icons, and the menu area includes a check menu 1210, a 3D depth change menu 1220, and the like. An icon selection menu 1230 is included.

In this case, the user may select the check menu 1210 to select a plurality of icons in the first layer. After the check menu 1210 is selected, visual effects in the form of a check 1250 may be applied to the icons 1240 and 1260 to which a touch input is applied by a user as shown in FIG. 12B.

When all of the icons for changing the 3D depth are selected, the user may operate the 3D depth changing menu 1220 to move all the checked icons to the second layer as shown in FIG. 12C.

If any icon is selected by the user after the similar icon selection menu 1230 is operated, icons having the same characteristics as the icon selected by the user may be selected together. Here, the same personality may mean that the nature of the indication target of the icon is the same. For example, when an icon indicating a document file is selected after the similar icon selection menu 1230 is operated, an icon indicating all document files of the corresponding layer may be selected at a time.

The method for changing the layer area displayed on the display unit or changing the position of the selected icon after the plurality of icons are selected and the 3D depth is changed through at least one of the methods described with reference to FIGS. In one embodiment of may follow the methods described above.

Next, a command input method for repositioning the 3D level of the selected icon in addition to the method of using the sensing module 140 will be described with reference to FIG. 13.

13A and 13B illustrate a command input method for reverting the 3D level of an icon whose 3D level is changed to before the change in the mobile terminal according to one embodiment of the present invention, respectively.

First, in FIG. 13A, it is assumed that two icons on the left side are selected by the user and moved from the first layer to the second layer through any one of the aforementioned methods. In this case, when a touch area of more than a predetermined area is detected on the touch screen, the selected icons may move back to the first layer. To this end, the user may touch the three fingers 1310 to the touch screen at the same time. Accordingly, the selected icons can be moved to the first layer at one time.

In this case, when a touch input having a touch area having a predetermined area or more exists (eg, double tapping) a plurality of times within a predetermined time, icons moved to the second layer may be selectively moved to the first layer. That is, when a touch input with a predetermined area or more is detected on the touch screen a plurality of times within a predetermined time, a predetermined visual effect (for example, translucent) is applied to icons existing in the second layer as shown in FIG. While the visual effect is valid, only the icon receiving a touch input from the user may be selectively moved to the first layer.

Meanwhile, a menu manipulation method may be used as shown in FIG. 12 to select a plurality of icons to be moved to the first layer. That is, a user selects a check menu and selects (ie, gives a check mark) from icons to be moved to the first layer, and then moves the checked icons to the first layer by manipulating the 3D level change menu. Can be.

Although the present invention has been described on the assumption of a three-dimensional user interface composed of two rectangular layers and four icons, this is merely an example, and the present invention is not limited to the arrangement, number and shape of layers and icons. In addition, icons may be replaced with other selectable and movable / copyable objects such as thumbnails, figures, text, menu buttons, and the like.

Further, according to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

A mobile terminal having a display unit capable of displaying a stereoscopic image as described above is not limited to the configuration and method of the above-described embodiments, but the embodiments may be modified in various ways. All or some of these may optionally be combined.
