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.

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, it is assumed that a mobile terminal to which the present invention is applicable has a touch screen.

Also, an arrow or finger graphic for pointing to a specific object or selecting a menu on the display unit 151 is generally referred to as 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 the present specification, the graphic displayed on the display unit 151 is referred to as a cursor to clearly distinguish the two, and a physical means capable of performing touch, proximity touch, and gesture such as a finger or a stylus pen is referred to as a pointer. It is called.

The user may change the position of the objects to suit their preferences through manipulation and touch of the menu.

Examples of the object include an object including an icon, a widget, a plurality of icons, or a plurality of widgets, and the present invention is not limited thereto and may be implemented in various forms.

In this case, in addition to managing each object individually, if a user can arrange and manage them in groups, greater convenience is provided to the user.

In other words, if individual objects are arranged in a stacked stack of three-dimensional objects, they occupy less area on the touch screen, which makes it possible to use other areas and manage related objects together. There is an advantage.

However, in order to create a three-dimensional object stack including a plurality of objects, when the distance difference between different objects is within a predetermined threshold distance, the shape is arranged up and down in the object stack. Since there is a problem in which the method of determining is not clearly presented, a method for conveniently determining this is required.

In the present invention, a function for providing an efficient user interface by displaying a touch area for determining the vertical position of each object in the object stack is provided. Hereinafter, various embodiments will be described in detail.

First Example

According to an embodiment of the present invention, when the distance difference between different objects among the plurality of objects displayed on the touch screen is within a preset threshold distance, the touch area is displayed, and the upper and lower positions of the plurality of objects through the touch area. When is determined, different display depths may be given to generate a stereoscopic object stack.

Hereinafter, for convenience of description, an object dragged by a user among a plurality of objects is referred to as a first object, and an object that is within a predetermined threshold distance from the first object is referred to as a second object.

In order to describe the above-described three-dimensional object stack in more detail with reference to Figure 4 will be described below.

4 is a diagram illustrating a three-dimensional object stack given a display depth according to an embodiment of the present invention.

In FIG. 4, it is assumed that the object is a layer object, and will be described below.

Referring to FIG. 4A, a total of three layer objects from layer 1 to layer 3 may be arranged in a stacked form at a predetermined interval in the three-dimensional space. When the layer objects are implemented in the three-dimensional structure through the touch screen, the layer 1 has the highest display depth so that the user feels the layer 1 at the top and close to the user. In addition, as the layer 3 passes through the layer 2, the placement height gradually decreases, and the display depth is deep so that the user feels far from the user.

In addition, the arrangement position and / or display depth of the layer objects may be changed through a predetermined touch input through the touch screen. Command input for manipulating the layer objects may be performed by a touch touch and a proximity touch through the touch screen 151.

As an example of changing the display depth of the above-described layer objects, it is possible to change the display depth through user manipulation.

More specifically, it is assumed that only the surface of the layer object having the display depth corresponding to the position of the layer 1 in the arrangement state of the layer objects as shown in FIG. 4B is clearly displayed. Further, it is assumed that the surface of layer objects (ie, layer 2 and layer 3) located at a display depth deeper than the position of layer 1 is covered by a layer object (ie, layer 1) located at a lower display depth.

Under this assumption, the display depth can be lowered to make it feel that all the layer objects are located closer to the user through a predetermined operation through the touch screen.

In this case, layer 2 has a display depth corresponding to the previous layer 1, and layer 3 has a display depth corresponding to the previous layer 2. Here, as shown, the surface of the layer 2 is most clearly displayed, and the surface of the layer 3 is covered by the surface of the layer 2.

Meanwhile, the layer 1 has a display depth lower than its previous position. In this case, the controller 180 may make the layer 1 transparent or translucent as the layer 1 moves away from the display depth of the layer 2.

Therefore, the first three-dimensional object stack composed of the first object and the second object can be provided to the user by the above method.

Reference is made to FIG. 5 to describe in more detail the contents of one embodiment of the present invention.

5 is a flowchart illustrating a method of determining a vertical position through a touch area when a distance difference between different objects is within a preset threshold distance in a user interface that can be implemented in a mobile terminal according to an embodiment of the present invention.

First, the user may enter the object location change mode to change the location of a plurality of objects displayed on the touch screen.

The object position change mode may be provided when the user manipulates a menu, and when the user enters the position change mode, the position of the object displayed on the touch screen may be changed by a user's touch of a specific pattern.

Examples of a touch input of a specific pattern for changing the position of the object may include dragging, long touch, proximity touch, long proximity touch, and multi-touch.

In the present specification, for convenience of description, the touch input of the specific pattern is referred to as the touch input of the first pattern.

In addition, assuming that the touch input of the first pattern is a drag, the contents of the present invention will be described below.

First, a first object of a plurality of objects may be dragged by a user so that a distance difference from the second object may be within a preset threshold distance (S510).

The critical distance may be predetermined in design or arbitrarily changed by a user.

When the distance difference between the first object and the second object is within a predetermined threshold distance, the controller 180 displays a predetermined touch area on a partial area of the touch screen to determine a vertical position between the first object and the second object. (S520).

The predetermined touch area may be implemented through various effects including color, pattern of a texture of a surface, blinking, size change, and at least a part of shape change, and may be freely implemented in some or all areas of the touch screen. Can be. Details related to the predetermined touch area will be described later with reference to FIGS. 6 and 7.

If a predetermined touch area is displayed on the touch screen, the user may determine the vertical position of the first object and the second object (S530).

When the vertical position is determined by the user, the controller 180 stacks the stereoscopic object in a predetermined form by giving different display depths to the first object and the second object in the stereoscopic space according to the determined vertical position. By generating, it can be displayed on the touch screen (S540).

For convenience of description, in the present specification, a solid object stack composed of a first object and a second object is referred to as a first three-dimensional object stack.

Accordingly, the user may generate a first three-dimensional object stack in which a desired object is disposed up and down in accordance with his or her preference.

Meanwhile, when the distance difference between different objects is within a predetermined threshold distance, the touch area for determining the vertical position of the object will be described in more detail with reference to FIGS. 6 and 7.

6 is a diagram illustrating a method of determining an up and down position through a touch area according to an exemplary embodiment of the present invention.

First, referring to FIG. 6A, a user enters an object position change mode and drags a first object 612 of a plurality of objects displayed on a touch screen, so that the first object 612 is connected to the second object 611. The distance difference may be within a predetermined threshold distance.

In this case, as shown in FIG. 6B, the controller 180 displays a predetermined touch area 620 on a portion of the touch screen to determine the vertical position.

In FIG. 6B, the predetermined touch area 620 is positioned at the center of the first object and the second object. However, the touch area 620 is merely an example and may be variously implemented without any limitation in shape and size.

When the predetermined touch area 620 is displayed on the touch screen, the user may determine the vertical position of the first object 612 and the second object 611. In FIG. 6B, the user may determine the first object 612. The up-and-down position is determined so that is located below the second object 611.

When the top and bottom positions of the first object 612 and the second object 611 are determined, as shown in FIG. 6C, the first stereoscopic object stack under which the first object 612 is positioned below the second object 611 is shown. (stack) is created.

In addition, as described above, the predetermined touch region is not limited in shape and size, and a function of providing a user with a user interface through a touch region different from the predetermined touch region in FIG. 6 will be described with reference to FIG. 7. Explain.

7 is a diagram illustrating a method of determining a vertical position of a first object and a second object through a touch area different from the touch area of FIG. 6 according to an embodiment of the present invention.

Referring to FIG. 7A, the user may allow the distance difference between the first object 712 and the second object 711 to be within a preset threshold distance in the object position change mode.

When the distance difference between the first object 712 and the second object 711 is within a predetermined threshold distance, as shown in FIG. 7B, a predetermined touch area 720 is formed in a portion of the second object 711. Can be displayed.

In this case, the user may touch the left side or the right side based on the central axis 730 of the predetermined touch area 720, and the upper and lower positions of the first object 712 and the second object 711 may correspond to each other. Is determined.

In FIG. 7B, the user touches the left side based on the central axis 730, and in this case, a first stereoscopic object stack in which the position of the second object 711 is positioned above the first object 712 is generated. .

That is, as shown in FIG. 7C, the second object 711 moves downward on the left side, the right side rises on the upper side, and the first object 712 is disposed in an empty space, so that the second object 711 moves on the first side. A first stereoscopic object stack is created that is above the object 712.

Therefore, the user may be provided with an efficient user interface through the touch area for determining the vertical position of the object.

2nd Example

Meanwhile, according to another exemplary embodiment of the present disclosure, when the distance difference between the first object and the second object is within a preset threshold distance by a touch input of the first pattern, the first object is changed according to the position of the first object that is changed. It can be controlled so that the vertical position in the three-dimensional object stack (stack) is determined.

The first three-dimensional object stack described above is generated by determining up and down positions of different objects through a predetermined touch area.

However, a method of determining an up and down position according to the changed position of the first object based on the position of the second object without using the touch area will be described in detail with reference to FIG. 8.

Hereinafter, it is assumed that the touch input of the first pattern by the user is a drag.

8 is a diagram illustrating a method of determining an up and down position according to a dragged position when a position of an object dragged in a mobile terminal is within a preset threshold distance according to another embodiment of the present invention.

Referring to FIG. 8A, the user drags the first object 812 in the object position change mode to move the position of the first object within a preset threshold distance area.

When the distance difference between the second object 811 and the dragged first object 812 is smaller than the threshold distance, as illustrated in FIG. 8B, the controller 180 may be generated according to the current position of the first object 812. Up and down positions of the first object 812 and the second object 811 in the first stereoscopic object stack may be determined.

That is, the first stereoscopic object stack depends on whether the position of the first object 812 is located above or below the X axis 820 at the current location of the second object 811. The up and down position in the inside is determined.

More specifically, referring to FIG. 8B, when the first object 812 is positioned above the X axis 820, the first stereoscopic object with the first object 812 disposed above the second object 811. The stack is created. On the contrary, when the first object 812 is positioned below the X axis 820, a first stereoscopic object stack in which the first object 812 is disposed below the second object 811 is generated. do.

Therefore, the user does not use a predetermined touch area for determining the vertical position between the first object and the second object constituting the first three-dimensional object stack, but based on the X axis of the position of the second object. Since the position of the object can be used to determine the vertical position in the first three-dimensional object stack, a more convenient user interface can be provided.

Third Example

According to another embodiment of the present invention, when the second object is a three-dimensional object stack in which at least one or more objects having different display depths are arranged in a predetermined form, the predetermined object is arranged in a space where the first object is to be arranged. Visual effects can be displayed.

In the above-described method of generating the first object stack, it is assumed that the first object and the second object are composed of one object.

However, when the second object is not a single object but is a three-dimensional object stack in which a plurality of objects having different display depths are arranged in a predetermined form, the first three-dimensional object stack in which the first object is generated The problem is that the user cannot clearly see what position is placed within the.

Therefore, in the present exemplary embodiment, a function of displaying a predetermined visual effect in a space where the first object is disposed in the first stereoscopic object stack to be generated may be provided to the user in advance to indicate the position where the first object is to be placed. have.

This will be described below with reference to FIG. 9.

Hereinafter, in order to prevent confusion with the generated first stereoscopic object stack, the stereoscopic object stack of the second object in which a plurality of objects having different display depths are arranged in a predetermined form is referred to as a second stereoscopic object. This is called a stack.

FIG. 9 is a diagram illustrating that a predetermined visual effect is displayed in a space in which a first object is to be arranged when the second object is a three-dimensional object stack. Referring to FIG.

Referring to FIG. 9A, the second object 911 has a second stereoscopic object stack including a plurality of objects. In this case, the user may drag the first object 912 in the object position change mode so that the distance difference from the second object 911 is within a threshold distance.

When the distance between the first object 912 and the second object 911 is within a preset threshold distance, the controller 180 may control the first object 912 and the second object 911 as illustrated in FIG. 9B. The predetermined visual effect 920 may be displayed in a space where the first object 912 is to be disposed in the first stereoscopic object stack to be generated.

As an example of this predetermined visual effect, the color or pattern of the texture of the object surface may be changed. However, this is merely an example, and the visual effects of the present invention are not limited thereto, and may be implemented as various effects including blinking, size change, and at least some shape change.

In addition, the user may change the position of the first object 912 to be arranged in the first stereoscopic object stack to be generated, and corresponding visual effects may be arranged and displayed in another space.

This will be described in detail with reference to FIG. 10. FIG. 10 is a diagram illustrating that a predetermined visual effect is changed corresponding to a direction in which a user drags a first object according to another embodiment of the present invention.

First, referring to FIG. 10A, a predetermined visual effect 1020 is displayed in a space to be disposed in a first stereoscopic object stack in which a first object 1012 is generated.

In this case, as shown in FIG. 10B, when the user drags the first object 1012 downward, the position of the predetermined visual effect 1020 is also moved downwardly corresponding to that shown in FIG. 10A.

On the contrary, as shown in FIG. 10C, when the user drags upward with respect to the first object 1012, the position of the predetermined visual effect 1020 displayed is correspondingly moved up than the position indicated in FIG. 10A.

Therefore, even when the second object 1011 is the second three-dimensional object stack, the user can change the space in which the first object 1012 is to be arranged, and select a space to be arranged through the predetermined visual effect 1020. It can be clearly recognized visually.

On the other hand, when the distance difference with the first object is within the critical distance, the second object, which is the second three-dimensional object stack, is unfolded in a two-dimensional form and displayed on the touch screen to provide visual convenience to the user. Can be.

This will be described with reference to FIG. 11.

FIG. 11 is a diagram illustrating that a second object, which is a three-dimensional object stack, is arranged in a predetermined two-dimensional form according to another embodiment of the present invention.

Referring to FIG. 11A, the second object 1111 has a second three-dimensional object stack including a plurality of objects, and the user drags the first object 1112 in the object position change mode to the second object. The distance difference from 1111 can be within a critical distance.

When the distance difference between the first object 1112 and the second object 1111 is within a threshold distance, as shown in FIG. 11B, the controller 180 may access the second object 1111 which is a three-dimensional object stack. Each of the included objects may be disposed in a two-dimensional plane and displayed on the touch screen.

Even in this case, a predetermined visual effect on which the first object 1112 is to be placed is displayed between the plurality of objects arranged in two dimensions, and the user can change the position of the first object 1112 more easily. Is provided.

In addition, the first object as well as the second object may be a stereoscopic object stack in which at least one or more objects having different display depths are arranged in a predetermined shape.

That is, when both the first object and the second object are a three-dimensional object stack, a problem is described, which will be described in detail with reference to FIG. 12.

12 is a diagram illustrating a case where a first object and a second object are a stereoscopic object stack in a mobile terminal according to another embodiment of the present invention.

Referring to FIG. 12A, unlike FIG. 10, the first object 1212 also has a stereoscopic object stack in which a plurality of objects have different display depths.

In this case, when the distance difference between the first object 1212 and the second object 1211 is within a threshold distance due to a user's manipulation, as shown in FIG. 12B, different depths of the second object 1211 may be set. The plurality of objects having a lower depth than the plurality of objects constituting the first object 1212 is disposed below the first object 1212 to generate a first three-dimensional object stack.

Here, although it is assumed that the second object 1211 is disposed at the bottom of the first object 1212 to generate a first three-dimensional object stack, the first object and the second object using the predetermined touch area described above. It is also possible to determine the up and down position of.

Accordingly, the user can easily create the first three-dimensional object stack even when the first object and the second object have the three-dimensional object stack.

Fourth Example

According to another embodiment of the present invention, the first stereoscopic object stack may be provided to the user as a stereoscopic 3D stereoscopic image.

Three-dimensional stereoscopic images implemented on the display unit 151 of the mobile terminal can be largely classified into two categories. The criterion of this division is whether different images are provided to both eyes.

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.

The first stereoscopic object stack described in the above-described embodiments of the present invention was a stereoscopic structure generated in a monoscopic manner belonging to the first category. However, the first stereoscopic object stack may be provided as a 3D stereoscopic image by a stereoscopic method belonging to the second category.

In this case, the aforementioned display depth may be implemented as a 3D depth.

Recently, as various 3D images can be implemented in a mobile terminal, a more convenient operation method through a 3D user interface is required. Therefore, a first stereoscopic object stack also needs to be provided to a user by a stereoscopic method. This is recognized.

Accordingly, the principle of binocular disparity, which is the most important element of the stereoscopic method, will be described in more detail with reference to FIG. 13.

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

In FIG. 13, assume a situation in which the cube 1310 is viewed with the naked eye in front of the eye level. In this case, the left eye planar image 1320 showing only three surfaces of the top, front, and left sides of the hexahedron 1310 is seen as the left eye. In addition, as the right eye, the right eye planar image 1330 showing only three surfaces of the top, front, and right sides of the cube 1310 is visible.

If the left eye plane image 1320 is reached in the left eye and the right eye plane image 1330 is reached in the right eye, even if the object is not actually an object in front of the eye, a person may feel as if the user actually sees a cube 1310.

As a result, in order to implement a stereoscopic image of a second category in a mobile terminal, the left eye image and the right eye image, which have been viewed with a certain parallax, must be separated and reached through the touch screen through the touch screen.

Next, a method of implementing a 3D stereoscopic image according to the second category will be described in detail.

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.

This will be described with reference to FIG. 14.

14 is a conceptual diagram illustrating a method of implementing a 3D stereoscopic image in a display barrier type display unit applicable to embodiments of the present invention.

The structure of the view barrier type display unit 151 for displaying a 3D stereoscopic image may have a configuration in which the switch liquid crystal 151b is combined with a general display device 151a. The optical parallax barrier 1400 may be operated using the switch liquid crystal 151b to control the traveling direction of the light as shown in FIG. 14A to separate the light to reach the left and right eyes. Therefore, when an image in which a right eye image and a left eye image are combined is displayed on the display device 151a, the image corresponding to each eye is seen from the user's point of view as if it is displayed in three dimensions.

In addition, as shown in FIG. 14B, the parallax barrier 1400 by the switch liquid crystal is electrically controlled so that all the light is transmitted, thereby eliminating separation of the light due to the parallax barrier so that the same image can be seen by the left and right eyes. It may be. In this case, the same function as that of the general display unit may be performed.

In FIG. 14, the parallax barrier is parallelly moved in one axial direction, but the present invention is not limited thereto, and a parallax barrier capable of parallel movement in two or more axial directions may be used according to a control signal of the controller 180. have.

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

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.

Accordingly, the first stereoscopic object stack may be provided to the user as a stereoscopic 3D stereoscopic image by the above-described method, so that a more convenient 3D user interface may be provided to the user.

Meanwhile, according to an embodiment of the present invention, the above-described method may be implemented as code that can be read by a processor in a medium in which a 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.
