2A is a front perspective view of an example of a mobile terminal according to the present invention;

The disclosed portable terminal 1100 has a bar-shaped main 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 1101 and a rear case 1102. [ Various electronic components are embedded in the space formed between the front case 1101 and the rear case 1102. [ At least one intermediate case may be additionally disposed between the front case 1101 and the rear case 1102. [

The cases may be formed by injecting synthetic resin or may be formed of a metal material, for example, a metal material such as stainless steel (STS) or titanium (Ti).

The mobile terminal body, mainly the front case 1101, has a display unit 1151, an audio output unit 1152, a third camera 1121c, a user input unit 1130/1131, 1132, a microphone 1122, and an interface 1170. And the like can be arranged.

The display portion 1151 occupies most of the main surface of the front case 1101. A sound output unit 1151 and a camera 1121 are disposed in an area adjacent to one end of both ends of the display unit 1151 and a user input unit 1131 and a microphone 1122 are disposed in an area adjacent to the other end. The user input unit 1132 and the interface 1170 may be disposed on side surfaces of the front case 101 and the rear case 1102.

Contents input by the first or second operation units 1131 and 1132 can be variously set. For example, the first operation unit 1131 receives commands such as start, end, scroll, and the like, and the second operation unit 1132 receives a command to adjust the size of the sound output from the sound output unit 1152, The touch recognition mode can be activated or deactivated.

FIG. 2B is a rear perspective view of the portable terminal shown in FIG. 2A.

Referring to FIG. 2B, a third camera 1121c may be additionally mounted on the rear of the portable terminal body, that is, the rear case 1102. The third camera 1121c may be a camera having a photographing direction substantially opposite to the first and second cameras 1121a and 1121b and having the same or different pixels as the first and second cameras 1121a and 1121b. have.

The flash 1123 and the mirror 1124 may be further disposed adjacent to the third camera 1121c. The flash 1123 shines light toward the subject when the subject is photographed by the third camera 1121c. The mirror 1124 allows the user to see his / her own face or the like when the user wants to take a self picture (self-photographing) using the third camera 1121c.

The sound output module 1152 ′ may be further disposed on the rear surface of the portable terminal body. The sound output unit 152 ′ may implement a stereo function together with the sound output module 1152 (see FIG. 2A), and may be used to implement a speakerphone mode during a call.

In addition to the antenna for a call or the like, an antenna 1116 for receiving a broadcast signal may be additionally disposed on the side of the body of the portable terminal. The antenna 1116 constituting a part of the broadcast receiving unit 1111 (see FIG. 1) may be installed to be pulled out from the terminal body.

The terminal body is equipped with a power supply unit 1190 for supplying power to the portable terminal 1100. The power supply unit 1190 may be built in the terminal body or may be detachable from the outside of the terminal body.

The rear case 1102 may further include a touch pad 1135 for sensing a touch. The touch pad 1135 may be configured to be light transmissive for the display unit 1151. In this case, if the display portion 1151 is configured to output visual information from both sides (ie, in the direction of both the front and rear sides of the mobile terminal), the visual information may be recognized through the touch pad 1135. do. The information output on both surfaces may be controlled by the touch pad 1135.

Meanwhile, since a display dedicated to the touch pad 1135 is separately mounted, the touch screen may be disposed on the rear case 1102.

The touch pad 1135 operates in association with the display unit 1151 of the front case 1101. The touch pad 1135 may be disposed in parallel to the rear of the display unit 1151. The touch pad 1135 may have a size equal to or smaller than that of the display unit 1151.

Hereinafter, an operation method of the display unit 1151 and the touch pad 1135 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 1151. [ 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 1151 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 1151a and an input window 1151b are displayed at the top and bottom of the display unit 1151, respectively. The output window 1151a and the input window 1151b are areas allocated for outputting or inputting information, respectively. In the input window 1151b, a virtual keypad 1151c is displayed in which a number for inputting a telephone number or the like is displayed. When the virtual keypad 1151c is touched, a number or the like corresponding to the touched virtual keypad is displayed on the output window 1151a. When the first manipulation unit 1131 is operated, a call connection to the telephone number displayed on the output window 151a is attempted.

In addition to the input methods disclosed in the above embodiments, the display 1151 or the touch pad 1135 may be configured to receive a touch input by scrolling. The user can move a cursor or a pointer located on an object displayed on the display unit 1151, for example, an icon or the like, by scrolling the display unit 1151 or the touch pad 1135. [ In addition, when a finger is moved on the display 1151 or the touch pad 135, a path in which the finger moves may be visually displayed on the display 1151. This may be useful for editing the image displayed on the display unit 1151. [

In response to the display 1151 (touch screen) and the touch pad 1135 being touched together within a predetermined time range, one function of the terminal may be executed. 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. For example, the function may include activation or deactivation of the display 1151 or the touch pad 1135.

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 method of expressing a 3D image of a mobile terminal and a display unit therefor which can be applied in embodiments of the present invention will be described.

The stereoscopic image implemented on the display unit 1151 of the mobile terminal can be largely classified into two categories. The criterion for this classification is whether or not different images are provided in 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 1180 arranges a polyhedron generated through one or more points, lines, surfaces, or a combination thereof on a virtual three-dimensional space, and displays the image viewed from a specific point on the display unit 1151 . 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.

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

In FIG. 4, it is assumed that the hexahedron 410 is placed at the front lower than the eye level and viewed with the naked eye. In this case, a left-eye plane image 420 in which only the top, front, and left sides of the hexahedron 410 are visible in 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 410 is visible.

If the left eye plane image 420 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 actually an object in front of the eye, the person may feel as if the user actually sees the cube 410.

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 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 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.

FIG. 5 is a conceptual diagram illustrating a method of implementing 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 1151 for displaying 3D stereoscopic images may have a configuration in which the switch liquid crystal 1151b is combined with a general display device 1151a. The optical parallax barrier 500 may be operated by using the switch liquid crystal 1151b to control the traveling direction of the light as shown in FIG. 5A so that different lights reach the right and left eyes. Therefore, when an image in which the right eye image and the left eye image are combined is displayed on the display device 1151a, the user can see an image corresponding to each eye and feel as if the eye image is displayed as a three-dimensional image.

In addition, by controlling the parallax barrier 500 by the switch liquid crystal to electrically transmit all the light as shown in FIG. It may be. In this case, the same function as that of the general display unit may be performed.

5 illustrates that the parallax barrier moves in parallel in one axial direction, but the present invention is not limited thereto, and 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. 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.

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, it is assumed that the mobile terminal to which the present invention is applicable includes a touch screen capable of providing a 3D stereoscopic image to a user through at least one of the 3D stereoscopic image realization methods described above.

The present invention is intended to provide a more convenient stereoscopic user interface to a user, and more particularly to provide an interface using a plurality of layers.

The layer is a plane having a predetermined size, and its shape and size can be variously implemented. For example, it may be implemented as a shape such as a rectangle, a circle, a rhombus, and the like, and the size may be implemented in a part or whole area corresponding to the entire size of the display part.

A plurality of layers are displayed in three dimensions will be described in detail with reference to Figs. 6A to 8B.

6A-6C illustrate display state diagrams of a stereoscopic user interface that may be implemented in accordance with one embodiment of the present invention.

The following display state diagrams including FIGS. 6A to 6C are shown as a plane image at the representation limit of the drawing, but it is assumed that the stereoscopic image is provided to a user in the 3D stereoscopic image implementation described above.

Referring to FIG. 6A, a total of three layers from Layer 1 to Layer 3 may be stacked in a three-dimensional space at a predetermined interval.

When the 3D stereoscopic image is implemented through the touch screen, the layers have a low 3D depth so that the layer 1 is located at the top and is close to the user.

In addition, the arrangement height gradually decreases from Layer 2 to Layer 3, and has a deep three-dimensional depth to be felt far from the user.

These layers can be changed in placement position and / or three-dimensional depth through predetermined command input through the user input. Command input for manipulating the layers may be performed by a touch touch and a proximity touch through the touch screen 151.

As an example of changing the three-dimensional depth of the above-described layers, it is possible to change the three-dimensional depth through a user operation.

More specifically, it is assumed that only the surface of the layer of three-dimensional depth corresponding to the position of the layer 1 in the arrangement state of the layers as shown in FIG. 6A is displayed clearly.

Further, it is assumed that the surfaces of layers (ie, layer 2 and layer 3) located deeper than the position of layer 1 are covered by layers located at lower three-dimensional depths (ie layer 1).

Under this assumption, as shown in FIG. 6B, the 3D depth may be lowered to make it feel that all the layers are located closer to the user by the predetermined operation through the touch screen.

In this case, the layer 2 has the three-dimensional depth corresponding to the layer 1 in FIG. 6A, and the layer 3 has the three-dimensional depth corresponding to the layer 2 in FIG. 6A. 6A, the surface of the layer 2 is most clearly displayed, and the surface of the layer 3 is hidden on the surface of the layer 2 .

Meanwhile, the layer 1 has a three-dimensional depth lower than its position in FIG. 6B. In this case, the controller 180 may make the layer 1 transparent or translucent as it moves away from the three-dimensional depth of the layer 2.

Through the operation of the mobile terminal described above, the user can clearly see the surface of the layer 2 without disturbing the layer 1.

If the user again deepens the three-dimensional depth of all the layers, the state will become as shown in FIG. 6A again. If the three-dimensional depths of all the layers are made lower, both the layer 1 and the layer 2 become transparent or translucent, So that the surface of the wafer W can be clearly displayed.

Hereinafter, in this specification, the three-dimensional depth at which the surface of the layer positioned at the corresponding depth, such as the three-dimensional depth of the layer 1 in FIG. 6A, appears clearly without discriminating the other clear layers is referred to as a "reference depth" for convenience.

6C shows a specific example in which the layer 2, not the layer 1, is expressed as a transparent layer in FIG. 6B.

A specific example in which the operation of the stereoscopic user interface described in Fig. 6 is applied to the menu operation of the mobile terminal will be described with reference to Figs. 7 to 8B.

7 illustrates an example in which a stereoscopic user interface that can be implemented according to an embodiment of the present invention is divided into layers.

Referring to FIG. 7, menus of horizontal relations are respectively mapped to layers 1 and 2, respectively. In other words, the menus mapped to the layer 1 and the layer 2 are menus that can be selected independently of each other, not the upper menus and the lower menus.

A method of selecting a menu list through manipulation of layers in the mapping relation as shown in FIG. 7 will be described with reference to FIG.

8A and 8B are display conceptual diagrams illustrating an example of menu selection through a stereoscopic user interface that may be implemented according to an embodiment of the present invention.

The basic assumptions of FIGS. 8A and 8B are similar to FIG. 6A, so that duplicate descriptions are omitted for simplicity of the description.

However, as shown in FIG. 7, icons corresponding to the menus mapped to the respective layers are displayed on the surfaces of the respective layers.

Referring to FIG. 8A, the menu icons (i.e., message, telephone directory, Internet, and control panel) mapped to the layer 1 are displayed clearly with the layer 1 positioned at the reference depth, and the layers 2 and 3 are displayed on the layer 1 The surface is invisible.

Here, the user may arrange the layer 2 as the reference depth by lowering the three-dimensional depth of the entire layers (ie, appearing to be close to the user) through a predetermined manipulation.

Accordingly, as shown in FIG. 8B, the layer 1 becomes lower in depth than the reference depth, becomes semi-transparent, and the menu icons (i.e., game, music reproduction, dictionary and alarm) mapped to the layer 2 as the layer 2 is located at the reference depth, Can be displayed clearly. The surface of layer 3 may be hidden from layer 2 and still not visible.

In the above-described three-dimensional stereoscopic layer structure, the whole may be displayed on the touch screen, but one layer may be displayed on the entire area of the touch screen.

On the other hand, a general off-line lecture has a disadvantage in that it causes discomfort due to visual field shift and fatigue accompanied by alternating textbooks on the front blackboard, lecturer, and desk.

Further, there is still a problem that a user has to check the display portion of the terminal and the textbook on the desk and the note to be written, even if lectures are taken using the mobile terminal.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an apparatus and method for simultaneously displaying moving picture information, teaching material information, and note information by using a plurality of three-dimensional layers having a 3D depth on a virtual three- And a method of controlling the mobile terminal.

That is, the present invention outputs moving picture information using a first layer, outputs textual material information using a second layer, and when a specific command is input, it is a transparent layer and at least a part of the first layer and the second layer And a method for outputting note information using a third layer displayed in a superimposed manner.

Hereinafter, for convenience of explanation, it is assumed that various pieces of information can be output through the plurality of three-dimensional layers.

9A to 9D are views showing a concrete example of simultaneously outputting moving picture information, teaching material information, and note information by using a plurality of three-dimensional layers.

Referring to FIG. 9A, a conventional example in which the moving picture information 1000 is represented through the mobile terminal 1100 is shown.

As described above, in the case of FIG. 9A, the user must alternately check the display portion of the terminal, the textbook on the desk and the note to be written.

9B shows an example in which the moving picture information 1000 is displayed at the upper end of the mobile terminal 1100 and the textbook information 2000 is displayed at the lower end of the mobile terminal 1100. [

In the case of FIG. 9B, although the user can check the moving picture information 1000 and the textbook information 2000 at the same time as in FIG. 9A, there is still a problem that a note to be written must be checked separately.

9C proposed by the present invention, the moving picture information 1000 and the textbook information 2000 are simultaneously displayed through the mobile terminal 1100, and the note information 3000 is displayed in the form of a transparent layer So that the textbook information 2000 is displayed on at least a part of the textbook information 2000.

When the contents of the present invention proposed in FIG. 9C are applied, video lectures and textbooks can be learned in a given field of view. Therefore, the user can change the gaze of the textbooks Learning deterioration due to fatigue occurring in the form is prevented.

In addition, video lectures and textbooks are solved in one direction of the learner 's gaze, so concentration is improved and learning efficiency is improved.

In addition, the textbook information (2000) at the bottom can be used by learner or lecturer to maximize the utilization of the textbook.

Further, the note information 3000 can be created, modified and deleted by the user. That is, as the moving picture information 1000 is reproduced, the user generates the note information 3000 through an action of underlining a corresponding area of the textbook information 2000, highlighting with a highlight pen, , Modify, and delete.

The note information 3000 may be generated through the user input unit 1130. If the display unit 1151 is a touch screen, the note information may be generated by a user directly inputting a touch on the touch screen.

However, the above-described creation, modification, and deletion of the note information 3000 is merely an example of application of the present invention, and the note information 3000 can be generated through a variety of actions. For example, when the sensing unit 1140 of the mobile terminal 1100 includes a gyro sensor, the control unit 1100 may generate and modify the note information 3000 using the motion information of the mobile terminal 1100 acquired through the gyro sensor , A deletion action may be performed

Therefore, the learning effect can be raised by generating the user-only note information 3000 optimized for the moving picture information 1000 and the textbook information 2000. The textbook information 2000 and the note information 3000 can be displayed in the resolution or Density (1: 1) according to the screen density (screen density). Therefore, it is also possible to accurately map words and sentences close to the position of the correction and the position of the correction.

FIG. 9D shows a more specific form of the invention shown in FIG. 9C proposed by the present invention.

9D, the moving picture information 1000 and the textbook information 2000 are simultaneously displayed through the mobile terminal 1100 and the note information 3000 is displayed in a transparent layer form so as to completely overlap with the textbook information 2000 .

At this time, the transparency of the displayed note information 3000 can be modified according to the user's operation.

Hereinafter, a specific implementation method of the present invention will be described with reference to FIG.

FIG. 10 is a flowchart for explaining a method of simultaneously outputting moving picture information, teaching material information, and note information, in accordance with the present invention.

Referring to FIG. 10, a first layer and a second layer arranged in a predetermined shape with a 3D depth on a virtual three-dimensional space may be displayed (S1100).

Hereinafter, it is assumed that the first layer outputs moving picture information and the second layer outputs teaching material information for the moving picture information for convenience of explanation.

However, the above contents are merely examples for applying the present invention, and various information such as video information, image information, and text information may be output through the first layer.

Similarly, video information, image information, text information, and the like may be output through the second layer.

In addition, the first layer and the second layer may be displayed completely separated from each other or at least partially overlapped.

For example, as described with reference to FIGS. 9C and 9D, the first layer and the second layer may be displayed in the separated areas by separating the entire area of the display 1151 at the same ratio.

As another example, a second layer may be displayed over a portion of the first layer or a second layer may be displayed in a partial region of the region of the first layer.

On the other hand, the textbook information 2000 output through the second layer may be a textbook automatically determined in correspondence with the textbook manually determined through the user input unit 1130 or the moving picture information 1000 output through the first layer .

In addition, a plurality of text materials, which are manually or automatically determined, may be stored in advance in the memory 1160 of the mobile terminal 1100.

In addition, the color of the textbook information 2000 may be changed according to at least one of the type of the moving picture information 1000 and the reproduction time.

Also, the position of the teaching material information 2000 may be changed according to at least one of the type of the moving picture information 1000 and the reproduction time.

When the first layer and the second layer are displayed on the display unit 1151, the moving picture information 1000 and the textbook information 2000 are simultaneously output as described above.

Thereafter, a command for outputting the note information 3000 through the user input unit 1130 may be input (S1200).

The command for outputting the note information 3000 may include a key button input, a selection command input of a predetermined menu, a command input through a predetermined operation, and the like.

In addition, when the display unit 1151 is a touch screen, the command for outputting the note information 3000 may be a touch input of a specific pattern to the touch screen. At this time, the touch input of the specific pattern to be applied may include a drag touch, a long touch, a proximity touch, a long proximity touch, a double touch, and a multi-touch.

In the past, there have been frequently used methods of lecturing on a reference book (teaching material) by writing a line or memo, or a separate handwritten note.

In contrast, the note information 3000 applied to the present invention is obtained by digitizing a conventional learning method written on a teaching material using a virtual area, and the third layer is implemented through a transparent layer, So that the user can directly create, modify and delete the corresponding contents. As a result, the convenience of the user can be greatly enhanced, and the learning efficiency can be increased.

When a command for outputting the note information 3000 is inputted, the controller 1180 controls the third layer, which is a transparent layer, to be overlaid on at least a part of the first layer and the second layer (S1300).

That is, the control unit controls the third layer, which is a transparent layer for outputting the note information 3000, to be overlaid on at least a part of the first layer or overlaid on at least a part of the second layer.

Particularly, in the present invention, it is assumed that the third layer, which is a transparent layer, is overlaid on at least part of the second layer, but the content of the present invention is not limited thereto.

Therefore, as shown in FIGS. 9C and 9D through the step S1300, the second layer and the third layer are overlapped with each other to simultaneously display the video information 1000 and the textbook information 2000 through the mobile terminal 1100. The note information 3000 is displayed to overlap at least a portion of the textbook information 2000 in the form of a transparent layer.

As a result, the traditional learning method of drawing a line and writing a note directly to the textbook was implemented digitally, so that the high efficiency from the learning of the form was inherited, the textbook was not damaged, Learning benefits in digital form have been added.

In addition, since the textbook information (2000) at the lower end is a part that can be written by the learner or lecturer, the effect of maximizing the utilization of the textbook is assured.

11 is a diagram for explaining a method of simultaneously outputting moving picture information, teaching material information, and note information when there is a touch input of a specific pattern.

FIG. 11 is intended to explain step S1200 described above in more detail.

In FIG. 11, the display unit 1151 is a touch screen, and the command for outputting the note information 3000 is a touch input of a specific pattern to the touch screen. At this time, I suppose.

Referring to FIG. 11, moving picture information 1000 is displayed on the first layer through the first layer, and text material information 2000 is displayed on the second layer. The user can now input the double touch 111 to a predetermined area of the touch screen.
