Organization description

FIG. 2 is a perspective view of a mobile terminal or a portable terminal according to the present invention, as viewed from the front.

The disclosed mobile terminal 100 has a bar-shaped terminal body. However, the present invention is not limited thereto, and can be applied to various structures such as a slide type, a folder type, a swing type, and a swivel type in which two or more bodies are relatively movably coupled.

The body includes a case (a casing, a housing, a cover, and the like) which forms an appearance. In this embodiment, the case may be divided into a front case 101 and a rear case 102. [ A variety of electronic components are embedded in the space formed between the front case 101 and the rear case 102. At least one intermediate case may be additionally disposed between the front case 101 and the rear case 102. [

The cases may be formed by injection molding a synthetic resin, or may be formed to have a metal material such as stainless steel (STS) or titanium (Ti) or the like.

The display unit 151, the sound output unit 152, the camera 121, the user input units 130/131 and 132, the microphone 122, the interface 170, and the like may be disposed in the front body 101 have.

The display unit 151 occupies most of the main surface of the front case 101. A sound output unit 151 and a camera 121 are disposed in an area adjacent to one end of both ends of the display unit 151 and a user input unit 131 and a microphone 122 are disposed in an area adjacent to the other end. The user input unit 132 and the interface 170 may be disposed on the side surfaces of the front case 101 and the rear case 102. [

The user input unit 130 is operated to receive a command for controlling the operation of the portable terminal 100 and may include a plurality of operation units 131 and 132. The operation units 131 and 132 may be collectively referred to as a manipulating portion and may be employed in any manner as long as the user operates in a tactile manner.

The contents inputted by the first or second operation unit 131 or 132 may be variously set. 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, a related operation of the display unit 151 and the touch pad 135 will be described with reference to FIG.

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 as an entire area or may be divided into a plurality of areas and operated. 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 will be useful for editing the 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 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

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

The proximity sensor 141 may be configured to output different proximity signals according to the 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 having proximity sensors capable of sensing three proximity depths 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 contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is positioned apart from the touch screen by a distance d ₃ or more, it is recognized that the proximity touch is released.

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

On the other hand, an arrow or finger-shaped graphic for pointing a specific object or selecting a menu in 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.

Hereinafter, a three-dimensional image display method of a mobile terminal and a structure of a display unit therefor, which can be applied to embodiments of the present invention, will be described.

Hereinafter, a three-dimensional image display method of a mobile terminal and a structure of a display unit therefor, which can be applied to embodiments of the present invention, will be described.

The stereoscopic image implemented on the display unit 151 of the mobile terminal can be roughly divided into two categories. The criterion for this classification is whether or not different images are provided in both eyes.

First, we describe the first stereoscopic image category.

The first category is monoscopic in that the same image is provided in both eyes, which is advantageous in that it can be implemented as a general display unit. More specifically, the controller 180 arranges a polyhedron generated through one or more points, lines, faces, or a combination thereof on an imaginary three-dimensional space, and displays the image viewed at a specific time on the display unit 151 . 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. In other words, the two eyes of a person see different plane images when they see the same thing 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. This binocular disparity will be described in more detail with reference to FIG.

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

In FIG. 5, it is assumed that the hexahedron 510 is placed on the front face lower than the eye level and viewed from the naked eye. In this case, a left-eye plane image 520 in which only the top, front, and left sides of the hexahedron 510 are visible in the left eye. In addition, a right-eye plane image 530 in which only the top, front, and right sides of the hexahedron 510 are visible in the right eye.

If the object is not an object in front of the actual eye but the left eye plane image 520 is in the left eye and the right eye plane image 530 is in the right eye, the person can feel as if he is actually seeing the cube 510.

As a result, in order for the stereoscopic image of the second category to be implemented in the mobile terminal, the left eye image and the right eye image of the same object, which are viewed with a time lag, should be distinguished from each other through the display unit.

In this specification, in order to distinguish the two categories described above, the stereoscopic image of the first category is referred to as "2D stereoscopic image" for convenience, and the stereoscopic image of the second category is referred to as "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 electronically driving a blocking device provided between a display unit and a binocular to control the traveling direction of light, thereby achieving different images in both eyes.

The structure of the display unit 151 of the field barrier type for displaying the 3D stereoscopic image may have a structure in which switch liquid crystals are combined on a general display device. The optical parallax barrier provided in the switch liquid crystal is operated to control the traveling direction of light so that different light beams can be separated from the left and right eyes. Therefore, when an image in which the right eye image and the left eye image are combined is displayed on the display device, the user can see the image corresponding to each eye and feel as if the eye image is displayed in three-dimensional form.

In addition, by electrically controlling the parallax barrier so that light is totally transmitted, it is possible to eliminate separation of light due to the parallax barrier so that the same image can be seen on the right and left eyes. In this case, the same function as the general display unit can be achieved.

In general, a parallax barrier provides a 3D stereoscopic image with one axis as a reference, but a parallax barrier capable of moving in parallel 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, 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

Eye image is alternately displayed at a predetermined cycle through the display unit and the user's eyeglasses are arranged such that when the image in the corresponding direction is displayed, the shutter in the opposite direction is closed, To reach the eye. That is, during the time when the left eye image is displayed, the shutter of the right eye is closed to allow the left eye image to be reached only in the left eye, and the shutter of the left eye is closed during the time when the right eye image is displayed.

For convenience of explanation, it is assumed that the mobile terminal referred to below includes at least one of the components shown in FIG. In particular, the mobile terminal to which the present invention can be applied includes a display unit capable of providing a 3D stereoscopic image to a user through at least one of the 3D stereoscopic image realization methods described above.

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

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

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

The following display state diagrams including FIG. 6 are assumed to represent a stereoscopic image that is presented to the user in the above-described 3D stereoscopic image implementation method, though it is shown as a plane image at the representation limit of the drawing.

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

In this layer structure, a predetermined transparency can be set for each layer. For example, if all layers are set to be semi-transparent, the user will be able to see the surface of each layer from layer 1 to layer 3. If only layer 2 is opaque, the user can see only the surface of layer 2 and translucent layer 1 and translucent layer 1, and layer 3 may not be visible.

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

In FIGS. 6B and 6C, only layers 1 and 2 exist. In the layer 2, three sub-layers 610, 620 and 630 having the same size as the layer 1 are assumed to be connected in the horizontal direction. It is also assumed that layer 1 is transparent or translucent.

Referring to FIG. 6B, the layer 1 has a size corresponding to the entire screen on the display unit, and the sublayer 610 located 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 exist in the virtual space while maintaining the shape of the layer 2, but only the sublayer 610 at the center is displayed on the display portion.

At this time, the user can 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 a drag or flicking (i.e., a touch pattern input in a bouncing manner after touching the pointer in one direction) The right sub-layer 630 may be displayed on the touch screen as shown in FIG. 6C by inputting the flicking touch. At this time, the layer 2 may move continuously according to the input (i.e., according to the duration or the input distance of the drag or flicking) for moving the layer 2 in parallel (i.e., scrolling) It can also be moved in sublayer units so that sublayers are displayed. When continuously moving, a part of the right side of the middle sublayer 610 and a part of the left side of the right sublayer 630 may be simultaneously displayed on the display part.

In addition, if an arbitrary layer is larger than a size corresponding to the entire screen of the display unit, the layer may not be divided into sub-layers but may exist as one layer.

In addition, the above-described arrangement of the sublayers is illustrative, and the present invention is not limited thereto and can be applied to various sublayers. For example, each sublayer may be vertically connected, or may be connected in a lattice form in the horizontal and vertical directions. In addition, the sublayers may be arranged in a manner such that they are not connected to each other in the same layer but spaced apart from each other by a predetermined distance.

In addition, the above-mentioned sub-layer may be an area including a predetermined number of icons, an area set by a user on an application execution screen, an area set to an application specific area or an area corresponding to one page of a document, Can be set to a size that can be displayed in one screen through the unit.

One or more icons may be placed in each of the above-mentioned layers. Here, one icon represents one file, or can perform a shortcut function for a specific file, an application, or a menu. In a stereoscopic user interface including a plurality of layers, there is a need for a method in which the user often changes the position of the icon or performs copying frequently, thereby performing it more conveniently.

Accordingly, in the present embodiment, in order to change the position of an icon located on an arbitrary layer (or a sub-layer) or change the 3D depth of the corresponding icon in order to perform copying, that is, We propose a method to perform location change. When this method is applied, the user changes the area displayed on the display unit in the existing layer while moving the icon from the layer where the icon was previously disposed to another layer, and then returns the corresponding icon to the existing layer It is convenient to do. This will be described with reference to FIG.

7 is a flowchart showing an example of a method for changing the 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 a plurality of layers including a layer having a reference 3D depth serving as a reference of 3D depth exist. It is also assumed that at least one icon exists in a layer having a reference 3D depth, and that a layer other than a layer having a reference depth has a completely non-blocking (i.e., transparent or translucent) layer having a reference 3D depth.

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

When 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, when the 3D depth of the selected icon is changed, it can be seen that the selected icon moves to the second layer to which the 3D depth is different from the first layer. In other words, moving an icon to each layer can mean that the icon has the same 3D depth as the moved layer. The position where the moved icon is disposed in the second layer is preferably a point corresponding to a point disposed in the first layer before movement (i.e., the same position as the user views the display unit, but the 3D depth is changed) The selected icon may be arranged at a predetermined position in the second layer.

At this time, it is preferable that the 3D depth (i.e., the 3D depth of the second layer) given to the selected icon is lower than the first layer (i.e., it is made closer to the user). In addition, a predetermined visual effect such as a semitransparent effect icon vibration (tremor), color change, or size change may be additionally given to the selected icon.

In addition, the icon may be separated from the first layer and moved to the second layer according to the touch type for icon selection, or may be additionally created in the second layer in a state where the icon remains in the first layer. In the former case, the icon is moved. In the latter case, the icon is copied.

When the 3D depth given to the icon selected by the user is changed, the user can move the selected icon and / or the first layer (S703).

The user can change the position of the icon on the second layer while maintaining the touch input for selecting the icon to move the icon. After the touch input for selecting the icon is released, the corresponding icon can be started on the second layer through the proximity touch (or by selecting the icon first through the proximity long touch and then touching the proximity). At this time, the user can change (i.e., scroll) the area of the first layer displayed on the display unit through the touching (e.g., dragging or flicking) rather than the proximity touching.

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

When the operation of the selected icon or the first layer (i.e., the change of the position or the change of the display area) is completed, the user can restore the icon to the 3D depth of the existing first layer (S704). For this purpose, the user may input a predetermined menu operation or touch input through the user input unit 130, or may allow the sensing module 140 to recognize a specific operation. When the sensing module 140 is used, the user can position the selected icon to the reference 3D depth by waving or tilting the mobile terminal.

Hereinafter, the icon moving method described with reference to FIG. 7 will be described in more detail.

FIG. 8 shows an example of a form in which layers and icons are arranged according to an embodiment of the present invention.

The following drawings including FIG. 8 conceptually show a stereoscopic user interface including a plurality of layers. Such stereoscopic user interface can be provided to a user through a display unit as a 3D stereoscopic image through a stereoscopic method.

8, a layer having a reference 3D depth (i.e., a first layer: layer 1) is arranged in the form of three zones, that is, sublayers 810, 820, and 830 horizontally connected to each other. And a second layer (layer 2) having a 3D depth lower than the first layer exists. At this time, it is assumed that the second layer itself is transparent. That is, the second layer is assumed to represent a preset 3D depth virtually and is not visible to the user. It is also 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 the user views the display portion, it is assumed that the transparent second layer is transparent and the intermediate sublayer 810 of the first layer is visible.

Here, the first layer may be a main menu screen, or may be an execution region of an application providing 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 icons in the stereoscopic user interface structure as shown in FIG. 8 will be described. In the following drawings including FIG. 9, a portion excluding a region displayed on the current display portion in the first layer may be partially omitted.

In the following embodiments including Fig. 9, it is assumed that the display unit is constituted by a touch screen.

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

9A, a user may touch a touch input (e.g., 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, .

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

9C, the user can input a drag (or flicking) touch 930 through the pointer 920 to the first layer to move the first layer to the left. Accordingly, the icons except for the message icon 910 in the first layer are shifted to the left on the display unit as shown in FIG. 9D, and a circular icon 950 located in the right sub-layer of the first layer can be displayed.

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

If the first layer has been moved by the desired amount, the user may enter a command to move the message icon 910 back to the first layer (e.g., when using the sensing unit 140, A lengthened proximity touch, etc.).

Accordingly, the message icon 910 may be moved to the first layer again as shown in FIG. 9E. Specifically, 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. That is, the icon appears to be vertically descending to the user. If another icon exists at a position where the icon is vertically lowered, the position of another existing icon is automatically changed to another point so that an empty space is created, and the corresponding icon can be moved to the created space. Alternatively, the icon moved from the second layer may be automatically moved to the 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 in a state where the icon to change the position disposed on the first layer is moved to the second layer, So that it can be moved to the first layer again.

In FIG. 9, the 3D depth of the selected icon is lowered. However, the 3D depth of the icon other than the selected icon may be deepened. This will be described with reference to FIG.

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

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

At this time, the user can apply the long touch input to the corresponding icon 1010 with the pointer 1020 as shown in FIG. 10B in order to move the message icon 1010.

Accordingly, icons other than the message icon 1010 can be moved to the first layer as shown in FIG. 10C. In this case, the user may feel that the icons other than the message icon are moving away from the user.

10D, the user moves the message icon 1010 to a desired position using the pointer 1020, and then transmits a command (e.g., a mobile terminal shake) for resetting the icons except for the message icon 1010 The icon position change can be completed as shown in FIG. 10E.

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

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

Referring to FIG. 10F, the basic layer structure is similar to FIG. 10A, but sublayer 1 1050 and sublayer 2 1060 exist in the second layer. At this time, four icons are arranged in the sublayer 1 1050 and two icons are arranged in the sublayer 2 1060. It is assumed that the sublayer 2 1060 is disposed on the right side of the sublayer 1 1050 and the area corresponding to the first layer and the virtual space above the first layer 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. Therefore, in the situation of FIG. 10F, the user sees the sublayer 1 through the display unit.

In the layer structure shown in FIG. 10F, all the icons except the message icon 1010 in the second layer are moved to the first layer as the message icon 1010 is selected as shown in FIG. 10g. At this point, only the three icons except for the message icon among the icons arranged in the sublayer 1 1050 are displayed at the user's point of view, but the icons of the sublayer 2 1060 are also moved to the layer 1 in the virtual space.

At this time, the touch input, which is applied to the touch screen after the icon other than the selected icon 1010 is moved to the first layer, is not applied to the selected icon 1010 but is displayed on the first layer It becomes an input for movement.

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

Then, the user can input an instruction for re-setting the icons except for the message icon 1010 (for example, waving the mobile terminal) to finish changing the icon position as shown in FIG. 10I.

On the other hand, according to another aspect of this embodiment, a plurality of icons can 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.

11A to 11C show an example of a mode for 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.

Referring to FIG. 11A, a user can select an icon positioned between two touch points using multi-touch using two pointers 1110 and 1120 so that a display unit and two touch points are generated. When a user desires to select a plurality of icons, a multi-touch can be sequentially applied to each icon. When the present method is applied, there is an effect that the touch input for selecting the icon on the first layer is different from the touch input for moving the icon moved on the second layer on the second layer.

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

12A to 12C each show an example of a form in which a plurality of icons are selected in a menu operation manner according to another aspect of an embodiment of the present invention.

It is assumed that the basic stereoscopic user interface structure in Fig. 12 is similar to Fig.

Referring to FIG. 12A, a menu region is provided at one edge of a first layer having a reference 3D depth and including a plurality of icons. The menu region includes a check menu 1210, a 3D depth change menu 1220, And an icon selection menu 1230 are included.

At this time, the user can select the check menu 1210 to select a plurality of icons from the first layer. After the check menu 1210 is selected, a check 1250 visual effect may be given to the icons 1240 and 1260 to which the touch input is applied from the user, as shown in FIG. 12B.

When all the icons to be changed in the 3D depth are selected, the user can manipulate the 3D depth change menu 1220 as shown in FIG. 12C to move all of the checked icons to the second layer.

If an icon is selected from 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 person indicated by the icon has the same personality. For example, if an icon indicating a document file is selected after the similar icon selection menu 1230 is operated, an icon indicating all the document files of the corresponding layer may be selected at a time.

A method of changing the layer area displayed on the display unit or changing the position of the selected icon after the 3D depth is changed by selecting a plurality of icons through at least one of the methods described with reference to FIGS. Lt; / RTI > may follow the methods described above in one embodiment of < RTI ID = 0.0 >

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

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

13A, it is assumed that two icons on the left side are selected from the user and moved from the first layer to the second layer through any one of the methods described above. At this time, if the touch area of a predetermined area or more is sensed on the touch screen, the selected icons may move back to the first layer. To this end, the user may simultaneously contact three touching screens 1310 with the touch screen. The icons thus selected can be moved to the first layer at a time.

In this case, when a touch input having a touch area of a predetermined area or more exists a plurality of times within a predetermined time (for example, double tapping), the icons moved to the second layer can be selectively moved to the first layer. That is, when touch input over a certain area is detected a plurality of times within a predetermined time on the touch screen, a predetermined visual effect (for example, translucency) is given to the icons existing in the second layer as shown in FIG. 13B, Only the icon that receives the touch input from the user can be selectively moved to the first layer while the visual effect of the first visual effect is valid.

On the other hand, in order to select a plurality of icons to be moved to the first layer, a menu operation method may be used as shown in FIG. In other words, the user selects the check menu and selects the icons to be moved to the first layer from the second layer (i.e., checkmarking), and then operates the 3D level change menu to move the checked icons to the first layer .

Although the present invention has been described on the assumption that a stereoscopic user interface composed of two rectangular layers and four icons is used, the present invention is not limited to the layout structure, number and type of layers and icons. In addition, the icon may be replaced with other selectable and moveable / copyable objects such as thumbnails, graphics, 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 the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal having the display unit capable of displaying the stereoscopic image as described above can be applied to the configuration and method of the embodiments described above in a limited manner, All or a part of the above-described elements may be selectively combined.
