Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

In addition, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (an image at a reference time point and an image at an expansion point), sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

As described above, the image output through the display unit 651 can be seen overlapping with the general visual field. The mobile terminal 600 can provide an augmented reality (AR) in which a virtual image is superimposed on a real image or a background and displayed as a single image by using the characteristics of the display.

The camera 621 is disposed adjacent to at least one of the left eye and the right eye, and is configured to photograph a forward image. Since the camera 621 is located adjacent to the eye, the camera 621 can acquire a scene viewed by the user as an image.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different wireless interfaces and / or physical layers. For example, wireless interfaces that can be used by a communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA) ), Universal mobile telecommunication systems (UMTS) (in particular Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications May be included.

Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to all communication systems including an OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system as well as a CDMA wireless communication system.

A CDMA wireless communication system includes at least one terminal 100, at least one base station (BS) (also referred to as a Node B or Evolved Node B), at least one Base Station Controllers (BSCs) , And a Mobile Switching Center (MSC).

In this case, a combination of one BSC and at least one BS may be referred to as a "base station ". The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS may be referred to as a plurality of cell sites.

A broadcast transmission unit (BT) transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT.

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the mobile terminal 100. The satellite 300 aids in locating the mobile terminal 100. Useful location information may be obtained by two or more satellites. Here, the position of the mobile terminal 100 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.

The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.

The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP can transmit a location information request message to the Wi-Fi location server.

The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi location server through the mobile terminal 100 or may be transmitted from the wireless AP to the Wi-Fi location server.

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

1, the mobile terminal according to the present invention may include Bluetooth (registered trademarks), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Field Communication), and Wireless USB (Wireless Universal Serial Bus).

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (e.g., a SIM (Subscriber Identification Module) or a USIM (Universal SIM)), a Secure micro SD and a sticker, or a logical medium For example, embeded SE (Secure Element)). Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin. Cards such as credit cards, transportation cards, and access cards are mounted on the security module in the form of an applet, and the security module can store card information on the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage details, and the card information of the access card may include at least one of a name, a number (e.g., It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. At this time, the data received from the mobile terminal by the tag may be coded into a data exchange format (NFC Data Exchange Format) defined by the NFC Forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. If the data received from the tag is a smart poster type, the control unit executes a browser (e.g., an Internet browser), and if the data received from the tag is a text type, the control unit can execute the text viewer. When the data received from the tag is a URI type, the control unit executes the browser or makes a telephone call, and if the data received from the tag is a general control type, it can execute appropriate operations according to the control contents.

When the NFC module is operated in a peer-to-peer (P2P) mode, the mobile terminal can perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. For P2P communication, a connection can be created between the mobile terminal and another mobile terminal. At this time, the generated connection can be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are exchanged consecutively. Through P2P communications, data such as business cards, contact information, digital photos, URLs in electronic form, and setup parameters for Bluetooth and Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Upon receipt of the response signal corresponding to the connection request signal, the controller 409 controls the mobile terminal 100 to be connected to the mobile terminal 100. The airport robot 400 can recognize the current position of the airport robot 400 as the current position of the mobile terminal 100. [ Accordingly, the airport robot 400 transmits a route guidance request from its current position to the destination to the server 300, and can transmit the guidance information to the mobile terminal 100 based on the received route information. The user may enter the destination into the airport robot 400 and then move to the destination while viewing the route guidance information displayed in the augmented reality mode on the mobile terminal 100 of the user. Since the route guidance information is displayed in the augmented reality mode, the user can understand the route more easily than the conventional technique. A detailed explanation will be given later.

Although the method in which the airport robot 400 receives the destination input has been described above, according to another embodiment of the present invention, the mobile terminal 100 may receive the destination input. For example, it is possible to receive a destination input through an application installed in the mobile terminal 100.

Next, a method of receiving the destination input by the airport robot 400 according to the embodiment of the present invention will be described with reference to FIGS. 8 to 9. FIG.

8 is a view for explaining a method of receiving an input of a destination through a search screen displayed on an airport robot according to an embodiment of the present invention. According to an embodiment of the present invention, the display unit 405 may display a search screen 800 as shown in FIG. The search screen 800 according to an embodiment of the present invention may include at least one of a search tool bar 801 and a recommendation destination selection bar 802. [ The search toolbar 801 serves to receive a specific destination input. The recommendation destination selection bar 802 displays some of the various places in the airport to help search without having to input the destination directly. The destinations displayed in the recommendation destination selection bar 802 may include a destination having a large number of users' searches, a destination having difficulty in finding a location, and a recommendation destination based on a user's previous destination input.

According to an embodiment of the present invention, options using intra-airport characteristics can be added when a destination is input. 9 is a diagram for explaining a method of receiving an option setting when a destination is input according to an embodiment of the present invention.

According to an embodiment of the present invention, the search screen 800 may further include an option setting bar 901 in addition to a search tool bar 801 and a recommendation destination selection bar 802. [

The option setting bar 901 plays a role of selecting a route among the various routes to the destination. For example, the option setting bar 901 may include a shortest route guidance item, a waypoint addition item, an automatic waypoint addition item, and a clear guidance item, but this is merely an example. The shortest route guidance item indicates the route that can move to the destination fastest. The additional route item is an item for receiving the intermediate destination directly from the user. The additional item of automatic stopover is an item to guide the route to the destination via recommended places by recommending the specific place using the characteristics in the airport when moving from the current location to the inputted destination. For example, when the user inputs the departure point as a destination at the entrance of the airport, the airport robot 400 can recommend a route from the entrance of the airport through the ticket ticket counter, roaming center, and drugstore to the departure station. This may have the effect of helping the user to hurry from the airport and not miss his / her tasks before departure. A clear route guidance item is an item that analyzes the population density of each area in the airport and recommends a route to a destination that is uncommon for people. The fact that the people in the airport are frequently moved and the burden of the people in the airport is large, and the possibility of analyzing the population density of each area through the cameras 500 installed in the airport, It is effective. In addition to the options described above, various options may be added using airport characteristics. In addition, items in the option setting bar 901 may be singly selected or plural selected.

6 will be described again.

As the airport robot 400 receives the destination input, the airport robot 400 and the mobile terminal 100 may be connected (S103).

The control unit 409 can transmit a connection request signal to the airport robot 400 as it receives the destination input. The wireless communication unit 110 may receive a connection request signal from the airport robot 400. The input unit 120 may receive a connection acceptance command or a connection refusal command in response to a connection request signal. The control unit 180 may transmit the received connection acceptance command or the connection rejection command to the airport robot 400. When the control unit 409 receives the connection acceptance command, the control unit 409 controls the connection with the mobile terminal 100. The airport robot 400 and the mobile terminal 100 may be connected via a Bluetooth or a short distance communication module, but the present invention is not limited thereto.

The airport robot 400 may transmit a route guidance request signal to a destination input from the current position to the server 300 (S105).

The airport robot 400 can identify the current position of the airport robot 400 as the position of the mobile terminal 100 when receiving the destination input.

The server 300 can determine the route from the current location to the destination (S107).

The server 300 can calculate various paths from the current position to the destination. The server 300 may determine any one of the calculated various paths as a path to guide the user. Alternatively, the server 300 may transmit all of the calculated various routes to the mobile terminal 100 through the airport robot 400. The user can directly check the various paths displayed on the mobile terminal 100 and select one of the paths.

Next, a method for the server 300 according to the embodiment of the present invention to determine the guiding path will be described with reference to FIGS. 10 to 12. FIG. 10 to 12 are views for explaining a method for determining a guide route to a destination according to an embodiment of the present invention.

According to an embodiment of the present invention, the server 300 may store the airport map 1000. [ The server 300 can calculate various paths from the current position of the airport robot 400 to the destination G based on the stored airport map 1000. [ The server 300 can determine the shortest path 1001 as a guiding path as shown in FIG. 10 among various paths. Alternatively, the server 300 can determine the route based on the option set at the destination input. For example, as shown in Fig. 11, an item of the route setting addition field may be selected in the option setting bar 901. Fig. The server 300 can receive the waypoint information from the airport robot 400. [ For example, if the server 300 receives the first intermediate point and the second intermediate point information together with the destination from the airport robot 400, the server 300 transmits the first intermediate point and the second intermediate point from the current position, It is possible to determine the route 1002 which is the fastest route to the destination G via the intermediate route as the guide route. 10 to 12 are merely illustrative.

6 will be described again.

The server 300 may transmit the determined route information to the airport robot 400 (S109).

The airport robot 400 may receive route information from the server 300. [

In addition, the wireless communication unit 110 may transmit a preview image related to the current position photographed through the camera 121 to the airport robot 400 (S111).

The airport robot 400 can receive a preview image related to the current position photographed through the camera 121 from the mobile terminal 100. [

The mobile terminal 100 may transmit the image photographed through the camera 121 to the airport robot 400 to inform the airport robot 400 of the current position of the user as the position of the mobile terminal 100 moves.

The airport robot 400 may update the guidance information based on the preview image received from the mobile terminal 100 and the route information received from the server 300 (S113).

The airport robot 400 may analyze the position of the mobile terminal 100 by analyzing the image received from the mobile terminal 100. Specifically, the controller 409 can obtain the current position of the mobile terminal 100 by comparing the image received from the mobile terminal 100 with the image related to the airport map. In addition, it may acquire not only the current position of the mobile terminal 100 but also the direction the mobile terminal 100 faces. In this way, the control unit 409 can acquire the current position, the moving direction, and the moving path of the mobile terminal 100.

The control unit 409 can update the guide information using the current position and route information of the mobile terminal 100 acquired through the received image. That is, the control unit 409 may update the guidance information related to the destination by reflecting the position of the mobile terminal 100 that changes as the position of the mobile terminal continuously changes.

The airport robot 400 may transmit the updated guidance information to the mobile terminal 100 (S115).

The guide information may include at least one of a current position of the mobile terminal 100, a position of a destination, a destination direction, and a distance from a current position to a destination.

The guide information may include a route from the current position of the mobile terminal 100 to the destination input to the airport robot 400 and at least one route included on the route. The waypoint can be determined by the frequency of the destinations input to the airport robot 400. For example, the destination most frequently input to the airport robot 400 may be included in the transit route.

The mobile terminal 100 may display the guidance screen on the display unit 151 based on the received guidance information (S117).

Specifically, the mobile terminal 100 may overlap the photographed image and the image related to the received guidance information and display the overlapping image on the display unit 151. Alternatively, the mobile terminal 100 may display on the display unit 151 at least one waypoint included in the movement path and the movement path.

The mobile terminal 100 may display the guide screen on the display unit 151 in the augmented reality (AR) mode by overlapping the received guide information with the preview image.

Next, with reference to FIG. 13 to FIG. 23, a method of guiding a destination in augmented reality mode according to an embodiment of the present invention will be described.

13 is a flowchart for explaining a method of guiding a destination in augmented reality mode according to an embodiment of the present invention.

The display unit 151 may display at least one destination icon by overlapping the preview image (S201).

The image associated with the guide information according to the embodiment of the present invention may include a destination icon, an arrow to guide the route, distance information, and the like.

The preview image may be an image showing the image to be photographed through the camera 121 in advance. Therefore, the preview image may include a real-world image. The display unit 151 may display at least one destination icon in an overlapped manner on the preview image. The at least one destination may include a destination previously input by the user, an intermediate waypoint, or a recommended waypoint.

Next, with reference to FIG. 14 to FIG. 17, a screen in which the display unit 151 according to the embodiment of the present invention overlaps and displays at least one destination icon on the preview image will be described.

FIG. 14 is a diagram for explaining a screen in which a display unit according to an embodiment of the present invention overlaps a preview image and one destination icon. FIG.

The route guidance information received by the wireless communication unit 110 may include one destination. The display unit 151 may display the first destination icon 1401 in an overlapped manner on the preview image 1400. The first destination icon 1401 may include a destination name. The first destination icon 1401 may be positioned in the direction of the destination on the preview image 1400. For example, the first destination icon 1401 may be located in the direction in which the destination is located even though the destination is not visible due to a building included in the preview image 1400. Further, the display unit 151 can further display the movement information 1410. [ The movement information 1410 may include at least one of a distance to the mobile terminal 100 and a destination, a travel distance of a route to the destination, and an estimated time. According to an embodiment of the present invention, movement information 1410 may be omitted.

15 is a view for explaining a screen in which a display unit according to the first embodiment of the present invention overlaps and displays a plurality of destination icons on a preview image.

The route guidance information received by the wireless communication unit 110 may include at least one waypoint and an input destination. Hereinafter, the destination is regarded as including both the stopover destination and the input destination. For example, the wireless communication unit 110 may receive route guidance information including four destinations. The display unit 151 may overlap and display the first destination icon 1401, the second destination icon 1402, the third destination icon 1403, and the fourth destination icon 1404 in the preview image 1400 . Each destination icon may include a destination name. Also, each destination icon may be located in a respective destination direction.

16 is a view for explaining a screen in which a display unit according to a second embodiment of the present invention overlaps a plurality of destination icons on a preview image.

The wireless communication unit 110 may receive route guidance information including four destinations as in the example of FIG. The display unit 151 may overlap and display the first destination icon 1401, the second destination icon 1402, the third destination icon 1403, and the fourth destination icon 1404 in the preview image 1400 . At this time, the display unit 151 may include the distance order information in each destination icon. Specifically, the display unit 151 assigns numbers to destinations in descending order of distance, and displays the assigned numbers on each destination icon. For example, referring to FIG. 16, 'G' of the first destination icon 1401 indicates the final destination, '3' of the second destination icon 1402 indicates the third waypoint, and third destination icon 1403 '2' of the fourth destination icon 1404 indicates the second stopover point, and '1' of the fourth destination icon 1404 indicates the first stopover point. At the same time, 'G' of the first destination icon 1401 is the farthest destination from the current location, '3' of the second destination icon 1402 is the destination located third far from the current location, '2' of the fourth destination icon 1403 may indicate that the destination is the second farthest from the current location, and '1' of the fourth destination icon 1404 is the closest destination from the current location.

17 is a view for explaining the operation of arranging the stopping route during route guidance according to the embodiment of the present invention.

The wireless communication unit 110 may receive route guidance information including at least one waypoint and an input destination. The user may want to delete some of the waypoints included in the route guidance information. In this case, the user can issue a specific waypoint deletion command.

The control unit 180 may receive a command to add or delete destinations displayed on the display unit 151. [ For example, the control unit 180 may add a waypoint by receiving a waypoint input through a separate menu (not shown). As another example, as shown in FIG. 17, the control unit 180 can delete the waypoint by receiving a command to drag and drop to the outside of the screen by selecting the waypoint to be deleted. The control unit 180 may not display the third way icon 1403 on the display unit 151 upon receiving the waypoint deletion command. In addition, the controller 180 can change the distance order information of the waypoint and display it by receiving the waypoint editing command.

13 is described again.

The control unit 180 may set the movement path to the closest destination as the current movement path (S203).

This is to help the user to move to the destination entered via the nearest waypoints from the current location. Accordingly, the user can reduce the spatial and temporal wastes as much as possible and can move to the destination.

The control unit 180 can determine whether the direction of the mobile terminal 100 is the same as the direction of the current movement path through the preview image (S205).

The control unit 180 can know the direction of the mobile terminal 100 through the preview image. Specifically, the control unit 180 may control the wireless communication unit 110 to transmit the preview image to the airport robot 400. The airport robot 400 can know the location of the preview image in the airport by using the shops, structures, and the like included in the received preview image. The airport robot 400 may transmit information indicating the position corresponding to the preview image to the mobile terminal 100. [ The control unit 180 can determine the direction of the mobile terminal 100 using the received information. The control unit 180 may determine whether the direction of the mobile terminal 100 is the same as the direction of the current movement path.

If it is determined that the direction of the mobile terminal 100 does not coincide with the direction of the current movement path (S207), the control unit 180 displays a guide indicating that the direction of the mobile terminal 100 coincides with the direction of the current movement path (S209).

The control unit 180 may determine whether the direction of the mobile terminal 100 coincides with the direction of the current movement path. In this way, the control unit 180 can determine whether the current moving route is included in the preview image. If the control unit 180 determines that the current moving route is not included in the preview image, the controller 180 may display a guide for directing the mobile terminal 100 toward the current moving route. Next, with reference to FIG. 18, a guide for indicating the direction of the mobile terminal 100 according to an embodiment of the present invention coincides with the direction of the current movement path.

18 is a view for explaining a guide for indicating a direction of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 18, the control unit 180 may guide the user to a position corresponding to the fourth destination icon 1404. At this time, the preview image 1400 may not include the path that the user should currently move. For example, the fourth destination icon 1404 should be positioned on the preview image 1400 in the direction of the fourth destination, but the mobile terminal 100 may be oriented in the other direction, Direction may not be included. In this case, the fourth destination icon 1401 may be positioned at the edge of the preview image 1400. Specifically, when the fourth destination icon 1404 is positioned at the upper right, it indicates that the mobile terminal 100 should be rotated rightward and then moved forward. If the fourth destination icon 1401 is positioned at the upper left, If the fourth destination icon 1401 is located at the bottom right, it indicates that the mobile terminal 100 should be rotated right and then backward. If the fourth destination icon 1401 is located at the bottom If it is positioned on the left side, it can indicate that the mobile terminal 100 should be rotated leftward and then backward.

If the preview image 1400 does not include the route to be currently traveled by the user, the control unit 180 displays the guide 1800 indicating that the direction of the mobile terminal 100 is directed toward the travel path The display unit 151 can be controlled. The display unit 151 can display the guide 1800 in an overlapping manner on the preview image 1400. The guide 1800 may include a message or image informing the user of the moving direction of the mobile terminal 100. [ The guide 1800 may continue to be displayed until the current movement path is included in the preview image 1400. [

13 is described again.

If it is determined that the direction of the mobile terminal 100 is the same as the direction of the current movement path (S207), the control unit 180 may display the overlapping guide information indicating the current movement route on the preview image (S211).

Next, referring to FIGS. 19 to 20, an operation of the display unit 151 according to an embodiment of the present invention to overlap and display guidance information on a preview image will be described.

19 to 20 are views for explaining an operation of overlapping and displaying guide information indicating a movement route on a preview image according to an embodiment of the present invention.

The control unit 180 may control the display unit 151 to display the guidance information 1900 indicating the movement path if the preview image 1400 includes the current movement path as shown in FIG. The display unit 151 may display the guidance information 1900 in an overlapped manner on the preview image 1400. [ The guide information 1900 may be information indicating in which direction to move. For example, the guidance information 1900 may include arrows as shown in Fig. The guidance information 1900 may include, in addition to arrows, a message indicating a movement direction and a movement distance. Further, the guide information 1900 is not limited to an arrow, and may be an image moving on a moving route.

Also, the controller 180 may control the display unit 151 to change the guide information 1900 according to the change of the preview image 1400. For example, as the user moves, the preview image 1400 will continue to change as shown in FIG. 19 through FIG. 20, and the movement path will also change as the preview image 1400 changes. Therefore, the control unit 180 can change and display the guide information 1900 so that the guide information 1900 changes according to the change of the preview image 1400.

13 is described again.

The control unit 180 can determine the current position (S213).

The control unit 180 can determine the current position through the preview image. The current position determination method based on the preview image is similar to the method of determining the direction of the mobile terminal 100 described in step S205.

According to one embodiment of the present invention, the control unit 180 can determine the current position at each time when the preview image is changed. According to another embodiment of the present invention, the control unit 180 may determine the current position every predetermined period.

The control unit 180 can determine whether the destination has been reached based on the current position (S215).

If it is determined that the destination has not been reached (S215), the control unit 180 can guide the route to the destination again (S205).

Alternatively, if it is determined that the destination has been reached (S215), the control unit 180 determines whether there is a next destination (S217). If there is a next destination, the route to the next destination can be reset to the current route (S219).

This allows the user to reach the destination via the waypoints.

FIG. 21 is a diagram for explaining a screen for resetting a movement path to a next destination according to an embodiment of the present invention to a current movement path. FIG.

As shown in FIG. 21, if it is determined that the destination corresponding to the current movement route has been reached, the destination icon 1404 corresponding to the current movement route may not be displayed on the display unit 151. In addition, the distance order information of the destination icon 1402 corresponding to the next destination can be changed and displayed first. At the same time, the guide 1800 can be displayed so that the mobile terminal 100 faces the next destination.

13 is described again.

If it is determined that there is no next destination (S217), the control unit 180 can terminate the connection with the airport robot 400 (S221).

The control unit 180 may determine whether the destination has been reached through the current location of the mobile terminal 100. [ The control unit 180 may control the wireless communication unit 110 to terminate the connection with the airport robot 400 when it is determined that the destination has been reached. This is because, when the user reaches the destination, the connection with the airport robot 400 is terminated, thereby preventing the airport robot 400 from being overloaded, .

The control unit 180 can terminate the route guidance.

22 to 23 illustrate a route guidance end screen according to an embodiment of the present invention. FIGS. 22 to 23 are views for explaining a screen at the end of a route wife according to an embodiment of the present invention.

When the controller 180 reaches the destination, the controller 180 may control the display unit 151 to display the destination icon 1401 at the destination position as shown in FIG. In addition, the control unit 180 may control the display unit 151 to display the route guidance message 2300 as shown in FIG.
