A GPS (Global Position System) module 119 receives position information from a plurality of GPS satellites.

The A / V (Audio / Video) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 123. The camera 121 processes an image frame such as a still image or moving image obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display unit 151. [

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ The camera 121 may be equipped with two or more cameras according to the configuration of the terminal.

The microphone 123 receives an external sound signal by a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station via the mobile communication module 113 and output when the voice data is in the call mode. The microphone 123 may be a variety of noise reduction algorithms for eliminating noise generated in receiving an external sound signal.

The user input unit 130 generates key input data that the user inputs to control the operation of the terminal. The user input unit 130 may include a key pad, a dome switch, a touch pad (static / static), a jog wheel, a jog switch, a finger mouse, and the like. Particularly, when the touch pad has a mutual layer structure with the display unit 151 described later, it can be called a touch screen.

The sensing unit 140 senses the current state of the portable terminal 100 such as the open / close state of the portable terminal 100, the position of the portable terminal 100, Thereby generating a sensing signal. For example, when the portable terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. In addition, a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is coupled to an external device, and the like can be handled.

The output unit 150 is for outputting an audio signal, a video signal, or an alarm signal. The output unit 150 may include a display unit 151, an audio output module 153, and an alarm unit 155.

The display unit 151 displays and outputs the information processed by the portable terminal 100. For example, when the portable terminal 100 is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the portable terminal device 100 is in the video communication mode or the photographing mode, the photographed or received images can be displayed individually or simultaneously, and the UI and the GUI are displayed.

Meanwhile, as described above, when the display unit 151 and the touch pad have a mutual layer structure to constitute a touch screen, the display unit 151 can be used as an input device in addition to the output device. If the display unit 151 is configured as a touch screen, it may include a touch screen panel, a touch screen panel controller, and the like. In this case, the touch screen panel is a transparent panel attached to the outside, and can be connected to a bus inside the portable terminal. The touch screen panel keeps a watch on the contact result, and if there is a touch input, sends the corresponding signals to the touch screen panel controller. The touch screen panel controller processes the signals, and then transmits corresponding data to the controller 180 so that the controller 180 can determine whether the touch input has been made and which area of the touch screen has been touched.

In the detailed description of the present invention, when the user operates the touch input unit, the display unit 151 is described as a touch screen. At this time, the touch screen is given the same reference numerals as the display unit 151 . Therefore, in the detailed description of the present invention, the display portion and the touch screen can use the same reference numeral "151 ".

The display unit 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, And a display (3D display). There may be two or more display units 151 according to the implementation mode of the portable terminal 100. [ For example, the portable terminal 100 may include an external display unit (not shown) and an internal display unit (not shown) at the same time.

The audio output module 153 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 153 outputs sound signals related to functions performed in the portable terminal 100, for example, a call signal reception tone, a message reception tone, and the like. The sound output module 153 may include a speaker, a buzzer, and the like.

The alarm unit 155 outputs a signal for notifying the occurrence of an event of the portable terminal 100. Examples of events occurring in the portable terminal 100 include call signal reception, message reception, and key signal input. The alarm unit 155 outputs a signal for notifying the occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, the alarm unit 155 may output a vibration to notify it. Alternatively, when the key signal is input, the alarm unit 155 can output the vibration by the feedback to the key signal input. This vibration output allows the user to recognize the occurrence of an event. Of course, a signal for notifying the occurrence of an event may also be output through the display unit 151 or the sound output module 153.

The memory 160 may store a program for processing and controlling the control unit 180 and may store a function for temporarily storing input or output data (e.g., a phone book, a message, a still image, .

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM , And a ROM. ≪ / RTI > In addition, the portable terminal 100 may operate a web storage for storing the memory 150 on the Internet.

The interface unit 170 serves as an interface with all external devices connected to the portable terminal 100. Examples of the external device connected to the portable terminal 100 include a card socket such as a wired / wireless headset, an external charger, a wired / wireless data port, a memory card, a SIM / UIM card, / Output, Video I / O, and Earphone. The interface unit 170 receives data from the external device or receives power from the external device and transmits the data to each component in the portable terminal 100 so that data in the portable terminal 100 can be transmitted to the external device .

The controller 180 typically controls the operation of the respective units to control the overall operation of the mobile terminal 100. For example, voice communication, data communication, video communication, and the like. In addition, the control unit 180 may include a multimedia playback module 181 for multimedia playback. The multimedia playback module 181 may be configured in hardware in the controller 180 or separately from software in the controller 180. [

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.

2 is a perspective view of a portable terminal according to an exemplary embodiment of the present invention. Referring to FIG. 2, the case of the present portable terminal 100 is formed by a front case 100A-1 and a rear case 100A-2. Various electronic components are incorporated in the space formed by the front case 100A-1 and the rear case 100A-2. At least one intermediate case may be additionally disposed between the front case 100A-1 and the rear case 100A-2. Such cases may be formed by injection molding of a synthetic resin, or may be formed of a metal material, for example, a metal material such as stainless steel (STS) or titanium (Ti).

The display unit 151, the first sound output module 153a, the first camera 121a, and the first user input unit 130a may be disposed in the main body, specifically, the front case 100A-1.

A second sound output module (not shown) may be additionally disposed in the front case 100A-1. The second acoustic output module may implement the stereo function together with the first acoustic output module 153a, and may be used for the talk in the speakerphone mode.

An antenna (not shown) for receiving broadcast signals may be disposed on one side of the front case 100A-1 in addition to an antenna for communication. The antenna may be installed to be able to be drawn out from the front case 100A-1.

The second user input unit 130b, the third user input unit 130, and the microphone 123 may be disposed on the side of the rear case 100A-2.

The display unit 151 includes a liquid crystal display (LCD), an OLED (Organic Light Emitting Diodes), and the like that visually express information. The display unit 151 may be constructed such that the touch pad is overlapped with the layer structure so that the display unit 151 operates as a touch screen so that information can be input by a user's touch.

The first acoustic output module 153a may be implemented in the form of a receiver or a speaker. The first camera 121a may be adapted to photograph an image or a moving image of a user or the like. The microphone 123 may be implemented in a form suitable for receiving voice, sound, etc. of the user.

The first to third user input units 130a, 130b, and 130c may be collectively referred to as a manipulating portion 130 and may be employed in any manner as long as the user operates the unit while giving a tactile impression.

For example, the user input unit 130 may be embodied as a dome switch or a touch pad capable of receiving a command or information by a push or touch operation of a user, or may be a wheel, a jog type, a joystick, Or the like. In terms of functions, the first user input unit 130a is for inputting a command such as start, end, and call, and the second user input unit 130b is for inputting an operation mode selection or the like. Also, the third user input unit 130c may operate as a hot-key for activating a special function in the portable terminal 100. [

3 is a schematic diagram illustrating a process of providing a real-time traffic information service using an extended reality function.

When the portable terminal 100 uses a map expressing a 2D or 3D terrain for the entire service target area, a separate application for expressing the transportation means on the map, and map data, the portable terminal 100 is provided with a large- Map information and applications should be installed. The augmented reality technology and the LBS (location based service) technology applied in the present invention use an image captured by the camera 121 as a background in place of the map data. Therefore, unlike a conventional real-time traffic information service method that requires map information and applications, it requires only a very small amount of data because it expresses the means of transportation on the background of low-capacity images picked up by the camera 121.

First, the user picks up one of a subway route map, a bus route map, a train route map, an airplane route map, and a ship route map using the camera 121 (1). The image captured by the camera 121 may be the entire route map or a part of the route map. The control unit 180 controls the wireless Internet module 115 to wirelessly transmit the image captured by the camera 121 to the traffic information providing system 200 (2).

The traffic information providing system 200 receives the image transmitted from the portable terminal 100 and acquires specific information from the received image to determine whether the user wants to see the traffic information. The specific information corresponds to the name of the station or area constituting the route map, and refers to the line connecting between stations (or areas) to determine the type and location of the vehicle for which the user wishes to receive the real-time traffic information service.

For example, when the image transmitted from the portable terminal 100 has names such as Apgujeong, Shinsa, Jamwon, and Express Bus Terminal and each name is connected by a single line, If the name of the station is listed in the image, in the order of "Western Transportation Origin - New Vicinity. Sungsigo Entrance - Myongji College - Hong Eun 2 dong Community Center - Culture Village Hyundai Apartment - Sangmyung University Entrance - Shinhyo Dong - Jongno 1 Ga" If so, it can be judged to be a bus route map.

That is, since the reverse names of the buses, the railways, the aircraft, and the vessels are different from each other in name and arrangement order, the traffic information providing system 200 can grasp the type of traffic information service desired by the user through the images.

The traffic information providing system 200 may transmit the real time traffic information directly to the mobile terminal 100 after selecting the type of traffic information to be provided to the user or may request real time traffic information from a separate service system providing real time traffic information , And after acquiring the data to the portable terminal 100. At this time, the traffic information providing system 200 may provide the portable terminal 100 with location information for each transportation means, type of transportation means, additional information about the transportation means, and icons for the transportation means.

Here, the traffic information providing system 200 may be configured to have both map information and traffic information, or may be configured to rely on an external service system (not shown) as either map information or traffic information. For example, the traffic information providing system 200 can acquire bus traffic information in the Seoul area from an external service system such as Seoul Bus Information System (SABIS).

The portable terminal 100 displays an image captured by the camera 121 on the display unit 151 and displays the type of transportation means transmitted by the traffic information providing system on the background of the image displayed on the display unit 151, Displays the location information of the transportation means. That is, the portable terminal 100 does not need a large-capacity map information to provide real-time traffic information to the user, nor does it need to install a separate application for displaying the map information on the display unit 151.

4 is a flowchart illustrating a method of controlling a mobile terminal according to an exemplary embodiment of the present invention.

First, the control unit 180 acquires an image of the route map captured by the camera 121 (S301), controls the wireless Internet module 115 to transmit the image captured by the camera 121 to the traffic information providing system 200 (S302). The traffic information providing system 200 analyzes the image provided from the portable terminal 100 to identify the type and area of the transportation means the user desires to view the real time traffic information, Time traffic information including additional information on the mobile terminal 100 to the mobile terminal 100.

Next, the controller 180 acquires the real-time traffic information transmitted by the traffic information providing system 200 through the wireless Internet module 115 (S303), and displays the image captured by the camera 121 on the touch screen 151 As a background image (S304).

Next, the controller 180 overlays and displays the real-time traffic information obtained from the traffic information providing system 200 on the background image (S305). At this time, the transportation means displayed on the background image may be any one of a vehicle, a subway, an aircraft, and a vessel, and the transportation means is preferably represented by an icon. The icon may be provided to the portable terminal 100 in the traffic information providing system 200 or may be expressed using an icon provided in the portable terminal 100 itself.

Next, the controller 180 determines whether a touch input is generated on the touch screen 151 (S306). When there is a user-selected transportation means among the transportation means displayed on the touch screen 151, the controller 180 displays additional information on the user-selected transportation means on the touch screen 151 (S307). The additional information includes unique information of the transportation means, for example, a bus number when the transportation means is a bus, a time required for the transportation means to reach the current position based on the user's current position, a moving direction, weather, traffic congestion, The average speed of the means, and the like. Likewise, when the transportation means is a train, it may be a train number, a direction of travel, and a scheduled arrival time. Here, the transportation means exemplifies a bus and a train, but is equally applicable to an aircraft or a ship. The transportation time, the moving direction, the weather information, the moving direction, the traffic congestion degree, May be displayed as additional information.

Here, the current position of the user may be acquired through the GPS module 119 incorporated in the mobile terminal 100 of the user, or may be acquired by using any one of the position information recognized by the base station when the mobile communication module 113 communicates with the base station Lt; / RTI >

FIG. 5 shows a reference drawing for an example in which a background image is displayed on a screen, and FIG. 6 shows a reference drawing for an example in which a transportation means and additional information are displayed in a background image.

First, referring to FIG. 5, there is shown a screen 400 on which a route map of the transportation means picked up by the camera 121 is displayed. In FIG. 5, an image obtained by capturing only a part of a subway route map by the user is displayed on the screen 400, and the captured image is expressed around the male area, the irrigation area, and the Nakseongdae area. This means that the user inquires traffic information around an area corresponding to an image taken in the entire route map area.

If the entire subway map is photographed, it may be easy to grasp the real-time traffic situation of the entire subway. Instead, the subway should be displayed in a very small area in the limited area of the screen 400. Conversely, if the user picks up only the area he needs, the route map displayed on the screen 400 and the icon of the transportation means will be enlarged and displayed in a size that is easy to identify. Furthermore, since the route map captured by the user corresponds to the route map frequently accessed by the user, it is very convenient to intuitively understand real-time traffic information.

Next, referring to FIG. 6, it can be seen that icons 451 and 455 for the transportation means change over time with the captured image as the background. When the touch input is applied to any one of the icons for the transportation means 451, the control unit 180 overlaps the touch screen 151 with the additional information 52 for the icon 451 to which the touch input is applied. The figure shows an example in which the train number 4984, the direction of travel (shrine -> Nyukseongdae), estimated arrival time calculated based on the current position of the user, and additional information 52 indicating the circulation train are displayed.

Here, it is preferable that the icon selected by the user's touch input, or the transportation means approaching the user's current position is emphasized and processed. The current position of the user may be acquired through the GPS module 119 by the control unit 180 or may be obtained by requesting current position information from the base station when the mobile communication module 113 and the base station communicate with each other. The color, brightness, size, and thickness of the outline of the transportation means selected by the user's touch input are preferably differentiated from other icons (e.g., 455). For example, the colors of the user-selected icons may be brightened, bold outlined, colors may be expressed in primary colors, or icons may be enlarged to distinguish them from other icons 455.

7 is a view for explaining an operational process of the portable terminal according to the present invention.

7, the control unit 180 of the portable terminal 100 of the present invention acquires an image of a public transportation route map imaged by the user through the camera 121 and transmits an image of the public transportation route map to the touch screen 151 ). At this time, the control unit 180 transmits the image captured using the wireless Internet module 115 to the traffic information providing system 200, and transmits traffic information corresponding to the route map captured in the image from the traffic information providing system 200 .

The traffic information providing system 200 analyzes the image transmitted by the wireless Internet module 115 and refers to the text displayed on the public transportation route map included in the image and the relationship between texts to determine the type of public transportation desired by the user And transmits to the wireless Internet module 115 traffic information based on the type of the identified mass storage box and the center of the image acquired from the wireless Internet module 115.

The control unit 180 displays the icon 510 for the transportation means on the image displayed on the touch screen 151 by referring to the traffic information obtained from the traffic information providing system 200. [ The control unit 180 continuously receives the traffic information of the traffic information providing system 200 through the wireless Internet module 115 and moves the icon 510 from the image in real time by referring to the received traffic information. Accordingly, the user can acquire and use the traffic information for the desired transportation means in real time.

In FIG. 7, the user may apply a touch input to the icon 510 displayed on the touch screen 151. When the user applies a touch input, the touch screen 151 displays additional information for the vehicle corresponding to the icon 510. [ 7, the additional information includes the train car number, the driving direction, the expected arrival time, and the like. The expected arrival time is determined based on the current position of the portable terminal 100 obtained through the GPS module 119 And the time distance between the portable terminal 100 and the train.

In FIG. 7, the icon 510 displayed on the touch screen 151 has the form of a train. The icon having the form of a train may be displayed by the flash player, or the control unit 180 may change the position of the stopped image according to the passage of time. The icon 510 may be stored in the memory 160 or may be provided to the wireless Internet module 115 in the traffic information providing system 200.
