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 visual information may be displayed on the display 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 1151 may operate in the 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 1151a and an input window 1151b are displayed on the upper and lower portions of the display 1151. The output window 1151a and the input window 1151b are areas allocated for output or input of information, respectively. The input window 1151b outputs a virtual keypad 1151c in which numbers for inputting a telephone number or the like are 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 an image displayed on the display 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.

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

Hereinafter, a method of expressing a 3D image of a mobile terminal and a display unit therefor that 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. In more detail, the controller 1180 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 1151. 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. 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. Such binocular disparity will be described in more detail with reference to FIG. 4.

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

In FIG. 4, it is assumed that the hexahedron 410 is viewed from the naked eye in front of the eye level. In this case, the left eye planar image 420 is seen in which only three surfaces of the top, front, and left sides of the hexahedron 410 are visible. 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 the present specification, in order to distinguish the above two categories, for convenience, a stereoscopic image of the first category is referred to as a "2D stereoscopic image", and a stereoscopic image of the second category is referred to as a "3D stereoscopic image".

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

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

1) parallax barrier method

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

This will be described with reference to FIG. 5.

FIG. 5 is a conceptual diagram illustrating a method of implementing 3D stereoscopic images 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 using the switch liquid crystal 1151b to control the traveling direction of the light as shown in FIG. 5A to separate the light to reach the left and right eyes. Therefore, when the combined image of the right eye image and the left eye image is displayed on the display device 1151a, the user's point of view of the image corresponding to each eye is felt as if displayed in three dimensions.

In addition, by controlling the parallax barrier 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 a 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 aforementioned 3D stereoscopic image implementation methods.

The present invention is to provide a user with a more convenient three-dimensional user interface, in particular to provide an interface using a plurality of layers.

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

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

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

6A to 6C, the following display state diagrams are shown as planar images due to the limitation of the drawing, but it is assumed that the 3D stereoscopic image is provided to the user in the above-described 3D stereoscopic image implementation manner.

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

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, as the layer 3 passes through the layer 2, the placement height is gradually lowered, and the deep 3D depth is felt to be far from the user.

These layers may be changed in position and / or three-dimensional depth through a predetermined command input through the user input unit. 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 user manipulation.

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

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, layer 2 has a three-dimensional depth corresponding to layer 1 in FIG. 6A, and layer 3 has a three-dimensional depth corresponding to layer 2 in FIG. 6A. Here, since only the surface of the layer located at the depth of layer 1 of FIG. 6A is clearly displayed, as shown in FIG. 6B, the surface of layer 2 is most clearly displayed, and the surface of layer 3 is covered by the surface of 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 layers, the state becomes the same as that of FIG. 6A. If the three-dimensional depth of all the layers is lowered, both layer 1 and layer 2 become transparent or translucent and layer 3 The surface of can be clearly displayed.

Hereinafter, in the present specification, the three-dimensional depth such that the surface of the layer positioned at the corresponding depth, such as the three-dimensional depth of the layer 1, in FIG.

Meanwhile, FIG. 6C illustrates a specific example in which layer 2, not layer 1, is represented as a transparent layer in FIG. 6B.

In addition, 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 having horizontal relations are mapped to layer 1 and layer 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 menu and the lower menu.

A method of selecting a menu list through manipulation of a layer in the mapping relationship as illustrated in FIG. 7 will be described with reference to FIG. 8.

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.

Since the basic assumptions of FIGS. 8A and 8B are similar to those of FIG. 6A, redundant descriptions are omitted for simplicity of the specification.

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

Referring to FIG. 8A, the menu icons (i.e., messages, phone book, internet and control panel) mapped to Layer 1 are clearly displayed, with Layer 1 positioned at the reference depth, and Layer 2 and Layer 3 cover 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 is lower than the reference depth and becomes translucent, and as the layer 2 is located at the reference depth, menu icons mapped to the layer 2 (ie, game, music play, dictionary, and alarm) This can be displayed clearly. The surface of layer 3 is hidden by layer 2 and may still be invisible.

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, the general offline lectures have to alternate between the blackboard on the front, the lecturer and the desk to look at the textbooks caused by discomfort caused by shifting the view, there was a problem accompanied by fatigue.

In addition, even when taking a lecture using a mobile terminal, there is still a problem that a user must check by taking turns writing notes and textbooks on the display unit and the desk of the 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 video information using the first layer, textbook information using the second layer, and in the case of receiving a specific command, is a transparent layer and is applied to at least some of the first layer and the second layer. It is intended to provide a user with a method of outputting note information using a third layer that is overlaid.

Hereinafter, for convenience of description, it is assumed that various pieces of information may be output through the above-described plurality of three-dimensional layers.

9A to 9D illustrate a specific example of simultaneously outputting video information, textbook information, and note information using a plurality of three-dimensional layers.

First, referring to FIG. 9A, a specific example in which the conventional video information 1000 is expressed through the mobile terminal 1100 is illustrated.

As described above, in the case of FIG. 9A, the user should alternately check a textbook and a writing note on the display unit and the desk of the terminal.

Next, FIG. 9B illustrates an example in which the video information 1000 is displayed at the top of the mobile terminal 1100 and the teaching material information 2000 is displayed at the bottom of the mobile terminal 1100.

In the case of FIG. 9B, the user can simultaneously check the video information 1000 and the textbook information 2000, compared to FIG. 9A, but there is still a problem of separately checking the notes to be written.

Therefore, referring to the form of the invention shown in FIG. 9C proposed by the present invention, the mobile terminal 1100 simultaneously displays the video information 1000 and the textbook information 2000, and the note information 3000 is in the form of a transparent layer. In addition, at least part of the teaching material information 2000 is displayed to overlap.

When the contents of the present invention proposed in FIG. 9c are applied, the video lectures and textbooks can be learned within a given field of view. Deterioration of learning due to fatigue occurring in the form is prevented.

In addition, since video lectures and textbooks are solved from the learner's perspective in one direction, the concentration is improved and the learning efficiency is increased.

In addition, the textbook information 2000 at the bottom is a part that can be corrected by a learner or a lecturer, so the utilization of the textbook may be maximized.

In addition, note information 3000 may be generated, modified, or deleted by a user. That is, as the video information 1000 is played back, the user generates the note information 3000 by underlining the corresponding area of the textbook information 2000, highlighting with a highlighter, erasing the lined part, and the like. Can modify, delete.

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

However, the above-described generation, modification, and deletion of the note information 3000 is merely an example to which the present invention is applied, and the note information 3000 may be generated through more various actions. For example, when the sensing unit 1140 of the mobile terminal 1100 includes a gyro sensor, the note information 3000 is generated and modified using the motion information of the mobile terminal 1100 obtained through the gyro sensor. In some cases, the deletion may be performed.

Therefore, the user's note information 3000 optimized for the video information 1000 and the textbook information 2000 is generated, thereby increasing the learning effect, and the textbook 2000 and the note information 3000 areas have resolution or density. Mapping is precisely 1: 1 with (screen density), which ensures the ability to accurately map words, sentences, etc. that are close to the corrected location.

Figure 9d is a more detailed representation of the form of the invention shown in Figure 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 .

In this case, the transparency of the displayed note information 3000 may be modified according to a user's manipulation.

Hereinafter, with reference to FIG. 10, a specific implementation method of the present invention will be described.

10 is a flowchart illustrating a method of simultaneously outputting video information, textbook information, and note information in relation to the present invention.

Referring to FIG. 10, first, a step of displaying a first layer and a second layer having a 3D depth and disposed in a predetermined shape in a virtual stereoscopic space may be performed (S1100).

Hereinafter, for convenience of explanation, it is assumed that the first layer outputs video information and the second layer outputs textbook information on the video information.

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, and likewise, the video information, Image information, text information, and the like may be output.

In addition, the first layer and the second layer may be displayed to be completely separated from each other, or may be displayed so that at least some of them overlap.

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.

For another example, the second layer may be displayed overlapping the partial region of the first layer, or the second layer may be displayed within the partial region of the region of the first layer.

The textbook information 2000 output through the second layer may be a textbook determined manually through the user input unit 1130 or a textbook automatically determined corresponding to the video information 1000 output through the first layer. .

In addition, a plurality of textbooks, which are determined manually or automatically, 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 and playback time of the video information 1000.

In addition, the position of the textbook information 2000 may also be changed according to at least one of the type and playback time of the video information 1000.

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

Thereafter, a command for outputting note information 3000 may be input through the user input unit 1130 (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 preset operation, and the like.

However, the four methods described below are merely examples for implementing the present invention, and it is obvious that the contents of the present invention can be realized through other forms.

The four methods proposed by the present invention are market model sharing service (first method), SNS and related community distribution service (second method), content selling service (third method), and direct file transfer service (fourth method). .

Hereinafter, the first to fourth methods will be described in detail.

1st way

The first method proposed by the present invention is a market model sharing service.

The market model sharing service is a format in which a user and / or a producer directly uploads the first information 4000 and another user (consumer) downloads the first information 4000.

At this time, the user and the producer who uploaded the first information 4000 may share the revenue with each other.

FIG. 17 illustrates a specific example of a smart learning market service in a method of easily sharing note information with another external device in relation to the present invention.

The market model sharing service disclosed in FIG. 17 registers lecture videos (1000, a), textbook information (2000, b), and note information (3000, c), which are created by a user based on smart learning software, and is used among other users. It shows the production / sales / consumer market service model that can be downloaded and used.

That is, in FIG. 17, the sharing of user-generated content is established as a market through an internal app and an external service.

Referring to FIG. 17, contents (a), (b), and (c) of a user-produced lecture may be produced through in-app software (S1710).

Next, the produced lecture can be posted on the server configured by the operator (S1720).

The publishing method applied to S1720 may include a smart learning internal publishing method and a method of making user-generated content into a PC.

If the smart learning internal posting method is applied, others may download the user-written lectures (a), (b), and (c) (S1730). Step S1730 may be paid, through which revenue can be generated.

Thereafter, the other user purchases the lectures (a), (b), and (c) produced by the user A, and may download and use them (S1740).

On the other hand, when the smart learning internal publishing method is applied, the details of the market may be linked with a separate service (S1750).

Finally, both the smart learning internal publishing method and the method of using the user-generated content as a PC are proceeding to settle lecture profits (S1760).

When the contents of the present invention described with reference to FIG. 17 are applied, it is possible to implement an integrated learning platform in which production / sale / consumption / settlement is performed at one time, content cost is reduced, and various contents are secured.

Referring to FIG. 18, the smart learning market service described in FIG. 17 is classified by using a consumer use (product) type and a producer sale & registration form.

First, looking at the type of consumer use (goods), the whole type is shown. In the entire type, a video (a), a textbook (b), and a note (c) are all selected, and the content producer means the first normal production.

Next, the basic type may include a video (a) and a textbook (b) without having to make a note.

In addition, the basic two types represent a case where a note is used as a textbook in a form including a video (a) and a note (c). That is, it shows the learning form that can be performed without the textbook.

In addition, the single type refers to a form that includes only the video (a) to buy and take only the video alone.

On the other hand, producer sales & registration forms are videos (a), textbooks (b), notes (c) in the form of individual registration, sales and registration on the basis of the individual, but packaged in the actual implementation of the service to sell according to product type or freely It means the form which is constituted.

2nd way

The SNS & related community distribution service directly distributes the first information 4000 produced by the users (producers and consumers). The first information 4000 may be easily shared through the SNS & related community distribution service.

3rd way

The third method proposed by the present invention is a content selling service. The content selling service is a sharing service in which an operator sells the corresponding learning output directly. The first information 4000 may be easily shared through the content selling service.

4th way

The fourth method proposed by the present invention is a direct file movement sharing service. The direct file movement sharing service refers to a method in which a user directly transfers generated first information to each other.
