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.
On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. 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 .
Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

A top-down method of arranging a left image and a right image in one frame according to a method in which a left image and a right image are combined into a three-dimensional stereoscopic image, A checker board system in which pieces of a left image and a right image are arranged in a tile form, a left-to-right (right-side) Or an interlaced method in which rows are alternately arranged, and a time sequential (frame-by-frame) method in which right and left images are alternately displayed in time.
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.

2 is a conceptual diagram for explaining another example of the mobile terminal 200 according to the present invention.
As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display, e-paper, and combinations thereof. In general, mobile terminal 200 may include features of mobile terminal 100 of Figures 1A-1C or similar features.
A typical flexible display refers to a sturdy display that is lightweight and does not break easily, such as paper, formed on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional flat panel display.
In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.
In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.
The flexible display unit 251 may be placed in a bent state (for example, a vertical state or a left-to-right bent state) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 may be deformed into a flat state (or a less bent state) or a more bent state.
Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

The deformation detecting unit may be provided in the flexible display unit 251 or the case 201 to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display unit 251 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformed flexible display unit 251 is restored, In addition, the flexible display unit 251 may be various information that can be detected due to the bending of the flexible display unit 251.
The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.
Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 that accommodates the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.
In addition, a battery (not shown) included in the mobile terminal 200 may be configured to be deformable together with the flexible display unit 251 due to an external force, taking into account the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.
The state change of the flexible display unit 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.
Meanwhile, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the dimension that the user mainly grasps and uses. These wearable devices include smart watch, smart glass, and head mounted display (HMD). Hereinafter, examples of a mobile terminal extended to a wearable device will be described.
The wearable device can be made to be able to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 can detect (or recognize) a wearable device capable of communicating with the mobile terminal 100. If the detected wearable device is a device authenticated to communicate with the mobile terminal 100, the control unit 180 may transmit at least a part of the data processed by the mobile terminal 100 to the wearable device 100 via the short- Lt; / RTI > Accordingly, the user can use the data processed by the mobile terminal 100 through the wearable device.

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).

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

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.

[ When the indoor positioning server 600 is implemented inside the mobile terminal 100, the wireless communication unit 610 may be implemented in the wireless communication unit 110 and the control unit 620 may be implemented in the controller 180, And the database 630 may be implemented in the memory 170. [0064]
Hereinafter, an example of the indoor positioning technique of the mobile terminal using the short-range communication according to the embodiment of the present invention will be described with reference to FIG. 5 and FIG. In FIG. 5, the triangulation method using the strength of a signal generated at an access point (AP) is taken as an example, but the scope of the present invention is not limited to this exemplary indoor positioning technique.
The AP 500 is a device that transmits or receives a radio signal for short-range communication. In the present specification, the term short-range communication refers to, for example, Wi-Fi, ZigBee, UWB, Wireless Local Area Network (WLAN), Bluetooth, WiMax, DTIM Traffic Indication Message) and a hot spot. In the present specification, however, it is assumed that the communication is short-distance communication using Wi-Fi.
The AP 500 transmits a radio signal including identification information of the AP and received signal strength indication (RSSI) information to the mobile terminal 100. The wireless signal may include other information besides the identification information and the RSSI information of the AP, but is not limited thereto. The identification information of the AP may include MAC address, SSID (Service Set IDentification), and the like as information necessary to identify each AP.

Specifically, the wireless communication unit 110, which receives the identification information and RSSI information of the AP from each of the APs 501, 502, and 503, may be the wireless Internet module 113 or the short-range communication module 114, The wireless communication unit 110 for transmitting the identification information and the RSSI information to the indoor positioning server 600 may be a mobile communication module 113, a wireless Internet module 113, or a local communication module 114.
The wireless communication unit 110 may periodically transmit the identification information of the mobile terminal 100 and the identification information and RSSI information of the received AP to the indoor positioning server 600 and may transmit the identification information of the AP 100 503 of the mobile terminal 100 only when it is determined that there is a change in the location of the mobile terminal 100 based on the identification information of the AP and the RSSI information received from the mobile terminal 100, To the indoor location server (600). The case where the position of the mobile terminal 100 is judged to be changed may mean a case where the identification information of the received AP changes or a value of the RSSI information of the AP changes (intensity of the signal).
The controller 620 of the indoor positioning server 600 receives the identification information of the mobile terminal 100, the identification information of the AP and the RSSI information from the mobile terminal 100 via the wireless communication unit 610, And performs the indoor positioning of the mobile terminal 100 based on the information stored in the database 630. The database 630 of the indoor positioning server 600 may store identification information and coordinate information of APs located in a specific building. The coordinate information of the AP may be a concept including the name of the building where each AP is located, the number of floors, the radar coordinate of each AP, and the like. The database 630 may also store information about the indoor map of the specific building, the number of layers of the specific building, the internal structure, and the like.

If the layer selected by the selection signal does not coincide with the positioned layer, the controller 180 maps the selected layer and the positioned coordinate value and stores the mapped coordinate value in the memory 170 (S765). That is, since the layer positioned in the specific building where the open space exists may be different from the layer where the mobile terminal 100 is located, the controller 180 repeats the above process to accumulate empirical data, It is possible to reduce the error of the positioning.
As a result of performing indoor positioning of the mobile terminal 100 based on information received from the APs 500 and information stored in the memory 170 at the mobile terminal 100, ) Is located, the layer positioned is the third layer, and the coordinate values positioned by the mobile terminal 100 are (X1, Y1, Z1). However, when the layer mapped to the coordinate values (X1, Y1, Z1) in the memory 170 is not the third layer but the second layer, the mobile terminal 100 calculates the coordinates (X1, Y1, Z1) The layer where the mobile terminal 100 is located is the second layer and when the result of the indoor positioning is outputted, the layer where the mobile terminal 100 is located is the second layer, not the third layer You can tell the user. As described above in connection with FIG. 14, when the controller 180 constructs this empirical data in the memory 170, the user can obtain the result of accurate indoor positioning There is an advantage to inform.
Hereinafter, with reference to FIG. 15 to FIG. 17, it is assumed that the mobile terminal 100 according to the movement of the user is located after the layer in which the mobile terminal 100 is currently located is determined according to the above- A method of detecting the transformation of a layer will be described.
In this specification, a method of utilizing a barometer as an environmental sensor included in the sensing unit 140 is proposed as a method of sensing the conversion of a layer in which the mobile terminal 100 is located. The barometer is a sensor for measuring the atmospheric pressure. It is assumed that the memory 170 stores information about the heights corresponding to the pressure values measured through the barometer. According to the embodiment, the barometer provided in the sensing unit 140 may output an altitude corresponding to the pressure value instead of the pressure value as a measured value.
FIG. 15 is a flowchart for explaining an example of a method of detecting a layer change of the mobile terminal 100 according to an embodiment of the present invention.
The control unit 180 of the mobile terminal 100 measures the atmospheric pressure through the barometer (S801). In one example, the control unit 180 can control the barometer to measure the atmospheric pressure when a selection signal for selecting a specific layer through the above-described GUI is sensed. In this embodiment, it is assumed that the specific layer is the second layer.
16 is a view for explaining an example of a pressure value measured through a barometer.
The pressure value measured through the barometer may indicate a fluctuation rather than a constant value. Also, the waveform of the fluxing may change at irregularity due to the influence of weather, humidity, temperature, and the like.
The controller 180 may use an average value of the pressure values belonging to the interval in which the deviation is less than a predetermined level among the pressure values measured through the barometer for a predetermined time. For example, among the pressure values shown in Fig. 16, an average value of the pressure values belonging to the first section, in which the deviation indicates a predetermined degree or less, can be used in this embodiment. The pressure values belonging to the second section, in which the deviation indicates a predetermined degree or more, may be a pressure value measured through the barometer in an unstable state, for example, when the user of the mobile terminal 100 is moving between layers.
Referring again to FIG. 15, the control unit 180 determines whether the pressure value measured in step S801 is greater than or equal to a first pressure value (for example, a pressure value Average value), the first altitude corresponding to the first pressure value is detected (S802). In the memory 170, altitude information corresponding to the pressure value is stored. In this embodiment, it is assumed that 5 m is detected as the first altitude corresponding to the first pressure value. The first altitude may not exactly coincide with the altitude at the current position of the mobile terminal 100 due to weather, humidity, temperature, and the like.
The control unit 180 detects a first height difference between the selected layer and another adjacent layer (S803). In the memory 170, information on the height of each of the plurality of layers of the specific building or the height difference between two adjacent layers may be stored.
17 is a view for explaining an example of information on heights of a plurality of layers of a specific building stored in a memory of a mobile terminal according to an embodiment of the present invention.
The memory 170 may store height information for each of a plurality of layers of a particular building or may store information about a height difference between two adjacent ones of the plurality of layers. In the present embodiment, it is assumed that the specific building is made up of four layers in total, and the height of each layer is stored in the memory 170. In one example, the height of the first layer is 0m, the height of the second layer selected by the user is 3.5m, the height of the third layer is 6m, and the height of the fourth layer is 10m.
Referring again to FIG. 15, the control unit 180 detects a first height difference between the selected layer and another adjacent layer based on the height information of the plurality of layers of the specific building stored in the memory 170 (S803). For example, 2.5 m as the height difference between the selected second layer and the adjacent third layer can be detected, and 3.5 m as the height difference between the selected second layer and the adjacent first layer can be detected.
Then, the control unit 180 controls the barometer to re-measure the atmospheric pressure periodically or non-periodically (S804). Step S804 does not necessarily have to be performed after step S803, but may be performed at any step after step S801.
The control unit 180 detects the second altitude corresponding to the re-measured second pressure value (S805). The second pressure value may be an average value of pressure values belonging to a section having a deviation of less than a predetermined degree among the pressure values measured through the barometer for a predetermined time, as described above with reference to FIG. The control unit 180 can repeatedly perform step S805 until the difference between the second altitude and the first altitude corresponds to the detected first height difference (2.5 m or 3.5 m).
When the difference between the second altitude and the second altitude corresponds to the detected first height difference (2.5 m or 3.5 m), the controller 180 determines the other layer as a layer where the mobile terminal 100 is located (S806). That is, it can detect that the layer where the mobile terminal 100 is located has been converted. If the difference between the second altitude and the second altitude corresponds to 2.5 m, the controller 180 can determine that the mobile terminal 100 is located in the third layer, and if the difference between the second altitude and the second altitude is 3.5 m, the controller 180 can determine that the mobile terminal 100 is located in the first layer. In this embodiment, it is assumed that the mobile terminal 100 is located in the third layer after the layer conversion is detected.
According to the embodiment, the control unit 180 repeatedly performs step S805 until the value obtained by adding the detected first height difference to the first altitude becomes the second altitude, and in step S806, If the detected first height difference plus the first altitude corresponds to the second altitude, the other layer may be determined as the layer where the mobile terminal 100 is located.
The control unit 180 performs the indoor positioning again based on the information corresponding to the APs located in the third layer (S807). The control unit 180 receives information corresponding to the APs located in the third layer from the identification information and RSSI information of the AP received from the in-building APs 500 through the wireless communication unit 100, The mobile terminal 100 can perform the indoor positioning of the mobile terminal 100 again.
Then, the control unit 180 outputs the result of the re-performed indoor positioning to the display unit 151 (S808).
18 is a view for explaining an example of a screen displayed on the display unit when a conversion of a layer in which a mobile terminal is located is detected according to an embodiment of the present invention.
Referring to FIG. 18 (a), when the layer on which the mobile terminal 100 is currently positioned is determined as the second layer according to the description of FIGS. 8 to 14, An indicator 811 corresponding to the coordinate value positioned by the mobile terminal 100 is displayed.
15, when the layer where the mobile terminal 100 is located is detected to be converted and then the indoor positioning is performed again, as shown in FIG. 18 (b) An indicator 821 corresponding to the coordinate value repositioned as the mobile terminal 100 is located on the indoor map 820 of the third layer, which is the floor where the mobile terminal 100 is currently located, is displayed.
Although the position of the mobile terminal 100 is changed from the second layer to the third layer in FIG. 15, the position of the mobile terminal 100 may be continuously changed from the third layer to another layer , The control unit 180 controls the operation of the mobile terminal 100 based on the pressure value measured through the barometer, height information of a plurality of layers of a specific building stored in the memory 170, and altitude information corresponding to the measured pressure value Layer conversion can be continuously detected.
According to the present embodiment, the user can accurately grasp the layer where the user is located in the specific building including the open space, and can precisely grasp the layer in which the user is located and the position in the layer . According to the present embodiment, there is an advantage that precise guidance including layer movement can be performed, particularly in a large shopping mall or a department store including an open space.
15 to 18 illustrate a method of sensing layer conversion in the mobile terminal 100 itself. However, in the mobile terminal 100, the pressure value measured by the barometer or the altitude information corresponding to the pressure value may be transmitted to the outside It is also possible to detect the layer change of the mobile terminal 100 in the external location server 600 by transmitting the location change to the location server 600. [
FIG. 19 is a view for explaining an example of a method of indoor positioning of a mobile terminal using local area communication according to an embodiment of the present invention.
When the location coordinate server 600 locates the mobile terminal 100 as a result of performing the indoor positioning of the mobile terminal 100, the location server 600 searches the location information of the mobile terminal 100, Can be determined to be located in the first layer. Here, the location location server 600 may be implemented inside the mobile terminal 100 or may be implemented outside the mobile terminal 100. That is, when the positioned coordinate value is located on the open space of the specific building, it is not necessary to take a step for knowing the layer of the mobile terminal 100 according to the description of FIGS. 8 to 14 to be.
According to the embodiment, when the positioning server 600 performs the indoor positioning of the mobile terminal 100 and the positioned coordinate value is located in the first area Q1 of the open space of the specific building, The mobile terminal 100 may perform the step of knowing the layer of the mobile terminal 100 according to the above description with reference to Figs. 8 to 14 without determining that the mobile terminal 100 is located in the first layer. The first area Q1 may correspond to an outer space of the open space of the specific building. When the coordinate value positioned in consideration of the error of the indoor positioning is located outside the open space of the specific building, the layer in which the mobile terminal 100 is actually positioned may not be the first layer. As a result of performing the indoor positioning of the mobile terminal 100 in the location server 600, it is possible to determine whether the coordinate value of the second area is located inside the first area Q1 in the open space of the specific building (Q2), it can be determined that the mobile terminal 100 is located in the first layer. 15 to 18 may be applied after the mobile terminal 100 is determined to be located in the first layer in this manner.
According to at least one of the embodiments of the present invention described above, the object of the present invention is to provide a mobile terminal that can accurately position a mobile terminal even when a user moves between layers in a building in which an open space including a plurality of floors such as a large shopping mall or a department store exists It is possible to provide an indoor positioning method that enables the user to know the location of the user.
