Meanwhile, the sensing unit 140 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a corresponding sensing signal. The control unit 180 may control the driving or operation of the mobile terminal 100 or may perform data processing, function or operation related to the application program installed in the mobile terminal 100 based on the sensing signal. 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 senses 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, do.

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, which touches the touch screen (or a touch key provided on the touch screen). Depending on the kind of the touch target object, whether to perform different controls or to perform the same control may be determined according to the current operating 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.

As shown in FIG. 18, the control system includes a mobile terminal 10, a plurality of reference devices 30, one or more electronic devices 50, and a DLNA source (Digital Living Network Alliance Source) in a room. Here, the mobile terminal 10 may be used as a DLNA control device, and the electronic device 50 may be used as a DMR (Digital Media Renderer). The DLNA source is a network technology standard for media transmission and control between terminals in the home. It uses Internet protocols such as HTTP, RTP / RSTP, etc. to share contents such as images, music and videos under WiFi, Ethernet and Bluetooth network environment. It provides a protocol that can be used. The DLNA source may comprise a data storage device that connects to the network, such as a NAS (Network Attached Storage) or a DMS (Digital Media Server).

7 to 9, the control unit 18 may register the electronic devices 50 as a DMR or a DMS, and may control the DMR and the DMS using any one of the control methods of FIGS. have.

19 and 20 are diagrams for explaining another example of the control method of the control system according to the present invention.

20, in the state where the mobile terminal 10, the plurality of reference devices 30, and the electronic device 50 are indoors and the remote control application included in the mobile terminal 10 is executed, The controller 18 adjusts the direction of the mobile terminal 10 or inputs the touch input (drag or flicking) to the display unit 15 so that the user faces the desired electronic device 50, From the memory (170) or the server (70) or measures the current position of the electronic device (50). The controller 18 uses the position and the direction of the mobile terminal 10 and the distance between the mobile terminal 10 and the electronic device 50 to measure the current position of the corresponding electronic device 50. [

The control unit 18 generates position information using the registered position or the measured current position of the electronic device 50 and transmits the generated position information to the corresponding electronic device 50. At this time, the control unit 18 can transmit the identification information of the electronic device 50 together with the position information.

Then, the electronic device 50 compares the position information transmitted from the control unit 18 with the measured position of the user through the wireless communication between the reference devices 30, and transmits the comparison result to the mobile terminal 10 Reply. Here, since the electronic device 50 has the IPS function, it is possible to measure its position through communication with the reference devices 30.

If the transmitted location information and the measured location are the same, the electronic device 50 responds to the mobile terminal 10 and executes a pairing procedure so that it can be controlled by the mobile terminal 10. On the other hand, if the transmitted location information differs from the measured location, the electronic device 50 does not respond to the mobile terminal 10.

21 is a view for explaining another example of the control method of the control system according to the present invention.

The control unit 18 can register a specific position in the indoor space and designate at least one of functions and applications of the electronic device 50 or the mobile terminal 10 in this specific position in the same manner as in Figs. have. The functions of the electronic device 50 or the mobile terminal 10 designated by the position of the indoor space can be registered in the map stored in the memory 17 or the server 70. [ For example, as shown in FIG. 21, a specific position around the TV may be designated as a movie mode execution position, or a sleep mode may be designated at a specific position around the illumination. In addition, a specific application (e.g., a calendar application) of the mobile terminal 10 may be designated to a calendar in the room. Here, the size of the specific location registered in the map can be changed / set by the user. For this, the controller 18 can provide a user interface for changing / setting the size of the designated specific location.

When the user directs the direction of the mobile terminal 10 toward the specific position of the indoor space or inputs a touch input (drag or flicking) to the display unit 15, the control unit 18 controls the mobile terminal 10 or And executes at least one of functions and applications of the electronic device 50 or the mobile terminal 10 specified at a specific location indicated by the touch input. Here, the controller 18 measures the current position of the mobile terminal 10 in the above-described manner to determine the specific position indicated by the mobile terminal 10 or the touch input, Determines the direction of the terminal 10 or the touch input, and then determines the specific position indicated by the mobile terminal 10 or the touch input.

If the mobile terminal 10 or the touch input is directed to a specific position around the TV, the control unit 18 can control the television to execute the movie mode. In addition, if the mobile terminal 10 or the touch input is pointing to a calendar in the room, the control unit 18 may execute the calendar application of the mobile terminal 10. [

22 is a view for explaining another example of the control method of the control system according to the present invention.

As shown in FIG. 22, the control system includes a mobile terminal 10, a plurality of reference devices 30, and one or more electronic devices 50 in the room. Here, the mobile terminal 10 may have a function of miracast that is connected to an electronic device based on Wifi-Direct. In addition, the electronic device 50 may have an IPS function. In this case, the mobile terminal 10 and the electronic device 50 can perform P2P pairing.

23 is a view for explaining another example of the control method of the control system according to the present invention.

The control unit 18 can register a specific position in a room in the same manner as in FIGS. 7 to 9 and designate an item frequently lost by the user at the specific position. For example, as shown in FIG. 23, after the position of the frequently lost object 53 is measured, it can be registered in the map stored in the memory 17 or the server 70.

Thereafter, when the frequently-lost object 53 is input to the mobile terminal 10, the control unit 18 informs the user of the specific position designated by the object 53. [

24 is a view for explaining another example of the control method of the control system according to the present invention.

The control unit 18 can register the position of each article in the shop in the same manner as in FIGS. The positions of the articles and the information about the articles can be registered in the map stored in the memory 17 or the server 70. [ Here, the information on the article includes information such as an article name, a price, a manufacturer, a manufacturing date, a sale / inventory quantity, and the like.

Thereafter, when the user adjusts the direction of the mobile terminal 10 so as to face the position of the article, the controller 18 displays information on the article on the display unit 15. In addition, it is also possible to display information on a plurality of articles at the same time by setting the scan beam of the mobile terminal 10 to be wide.

25 and 26 are diagrams for explaining a method of registering a position of a specific area in a room and generating a map relating to the specific area.

First, in a state where the application used to register the position of a specific area (e.g., the first and second areas) and to control the mobile terminal 10 is executed on the mobile terminal 10, (For example, a host or a manager) moves the mobile terminal 10 to a specific area located in the room (for example, a conference room). Here, the user may designate a desired area in the space as a specific area and approach the mobile terminal 10 to a distance smaller than a predetermined maximum allowable distance between the mobile terminal 10 and the specific area. 26, the control unit 18 sets the maximum allowable distance between the mobile terminal 10 and the specific area by the user. For this purpose, the controller 18 sets the maximum allowable distance on the display unit 15 / Offset < / RTI > In addition, the control unit 18 can set a virtual NFC tag in a specific area, designate a desired data or message in an NFC tag, and can change / set the size of a specific area according to a user's request. For this, the controller 18 may provide a user interface for setting a Tag and a user interface for changing / setting a size of a specific area.

At least one of the azimuth, inclination and height of the mobile terminal 10 is preferably adjusted so that the mobile terminal 10 faces a specific area to be registered. When the top of the mobile terminal 10 faces a specific area Or another part of the mobile terminal 10 may be directed to a specific area.

The control unit 18 measures the position of the mobile terminal 10 through the short distance wireless communication between the reference devices 30 and the communication unit 11 and measures the position of the mobile terminal 10 toward the specific area using the sensing unit 14. [ (10) and measures the distance between the mobile terminal (10) and a specific area. Here, in order to measure the position of the mobile terminal 10 by the triangulation method, the controller 18 calculates the distance between the at least three reference devices 30, the speed and the frequency value of the radio wave for short- The distance between the devices 30 and the mobile terminal 10 can be measured and the position of the mobile terminal 10 can be measured using these values. In addition, it is also possible to measure the position of the mobile terminal 10 using another triangulation method. For example, the distance between the mobile terminal 10 and a specific region may be measured using an ultrasonic sensor included in the sensing unit 14, Can be measured.

Next, the controller 18 measures the position and direction of the mobile terminal 10 and the actual position of the specific region using the distance between the mobile terminal 10 and the specific region. Since the distance between the mobile terminal 10 and the specific area is measured in the direction of the mobile terminal 10 toward the specific area at the current position of the mobile terminal 10, the controller 18 determines the position of the specific area in three dimensions It is possible to measure by position. That is, the position of a specific region can be expressed by coordinates (coordinates on a two-dimensional plane) and a height (high and low) in a room. It is also possible for the server 70 to measure the actual position of the specific region by using the position and direction of the mobile terminal 10 and the distance between the mobile terminal 10 and the specific region instead of the mobile terminal 10.

Then, the control unit 18 generates positional information of the specific area, and transmits identification information (ID, etc.) of the specific area to the memory 17 or the server 70 together with the generated positional information. The location information and the identification information of the specific area thus transmitted are transmitted to the memory 17 or the server 70.

This process is repeated to transmit and store the location information and the identification information for each specific area (the first and second areas) in the room to the memory 17 or the server 70, and the control unit 18 or the server 70 May generate a map for a specific area using the stored location information and the identification information.

FIGS. 27 and 28 are diagrams for explaining an example of a system control method using the registered specific areas of FIGS. 25 and 26. FIG.

27, when the mobile terminal 10 of another user (for example, a guest) moves to the first area or passes through the first area, the mobile terminal 10 of the guest moves to the reference devices 30, And transmits position information indicating the measured position to the mobile terminal 10 or the server 70 of the host.

Then, the mobile terminal 10 or the server 70 of the host determines whether the mobile terminal 10 of the guest has moved to the second area based on the transmitted location information. If the mobile terminal 10 of the guest has not moved to the second area, the mobile terminal 10 or the server 70 of the host can determine the distance or proximity between the mobile terminal 10 of the guest and the second area ) Of the guest, and information for guiding the direction or route of the guest from the mobile terminal 10 to the second area.

When the mobile terminal 10 of the guest moves to the second area, the mobile terminal 10 or the server 70 of the host transmits data or a message specified in the virtual NFC tag of the second area, for example, The guest terminal 10 can control the guest's mobile terminal 10 to transmit data or a message asking the user to the mobile terminal 10 of the guest and display the transmitted data or message on the mobile terminal 10 of the guest. Here, the mobile terminal 10 or the server 70 of the host can store data or messages designated in each specific area.

Then, if the guest indicates the presence or absence by pressing the "Enter" button of his / her mobile terminal 10, the mobile terminal 10 or the server 70 of the host can determine whether or not the guest is present. As described above, by using the system shown in FIG. 27 to FIG. 28, it is possible to automatically confirm whether or not a guest is present and to perform an unattended guidance.

29 to 49, a mobile terminal according to an exemplary embodiment of the present invention may be provided with a method of providing a different graphic image according to a relationship with a device to be controlled, a position, a direction, and the like I will explain. Further, the mobile terminal in the present specification can be implemented, for example, as a mobile phone or a separate device. Therefore, it is not necessarily limited to a mobile phone.

When a device to be controlled is pointed by using a mobile terminal equipped with an IPS (Indoor Positioning System) and a 9-axis sensor, information on device-related icons, shape information, connection path information, Will be described. Therefore, the mobile terminal described in this specification may be referred to as an IPS controller.

In order to enhance the user's convenience, a protocol for distinguishing between LOS (Line Of Sight) mode and NLOS (Non Line Of Sight) mode is defined. Furthermore, a solution for preferentially selecting the devices corresponding to the specific location to which the mobile terminal belongs will be described in detail below.

29 illustrates a system including a mobile terminal and at least one server according to an embodiment of the present invention. It is also within the scope of the present invention that the management server 2920 and the smart home solution server 2930 are implemented as a single server.

The mobile terminal 2900 shown in Fig. 29 includes, for example, both an IPS (Indoor Positioning System) and a 9-axis sensor. More specifically, the 9-axis sensor includes, for example, a 3-axis gyroscope, a 3-axis acceleration sensor, and a 3-axis magnetic field sensor.

In addition, the mobile terminal 2900 can be positioned by communicating with the anchor devices 2910 installed therein. In a typical IPS, two anchor devices are required for two-dimensional position determination and three anchor devices are used for three-dimensional position determination.

Meanwhile, the location information of the mobile terminal 2900 and the location information of other devices installed in the room are managed by the smart home solution server 2930. In particular, the smart home solution server 2930 has smart device related information, legacy device related information, virtual device related information, and the like, and is capable of a web service. For example, the server 2930 can receive information on the specific legacy device through the web service if the information is not provided for the specific legacy device.

Further, the management server 2920 is designed to serve as a gate between the mobile terminal 2900 and the smart home solution server 2930. Of course, it is also within the scope of the present invention to design such a role to be directly handled by the anchor device 2910, the mobile terminal 2900, or the smart home solution server 2930.

FIG. 30 shows the smart home solution related server shown in FIG. 29 in more detail. Hereinafter, with reference to FIG. 30, the smart home solution server 2930 shown in FIG. 29 will be described in more detail.

The smart home solution server 3020 receives location information through direct communication with the mobile terminal 3000 or receives location information of the mobile terminal 3000 through the cloud server 3010. [ Further, the smart home solution server 3020 is designed to transmit the location information of the controllable devices located indoors to the mobile terminal 3000.

Meanwhile, the first controllable device 3030, the second device 3040, the third device 3050, the fourth device 3060, and the fifth device 3070 located indoors are also connected to the smart home solution server 3020 ), And is designed to transmit and receive location information.

Further, as shown in FIG. 30, in the middleware of the smart home solution server 3020, at least one data is managed. For example, it includes a list of controllable devices, function, location of each device, user information, service information, driver information, connection path information, and gateway information. Particularly, in the present invention, position information is grouped so that more precise control is possible. For example, not only the absolute location of the device being controlled but also the relative location (ex: living room, bed room, and kitchen) are designed to store in memory.

FIG. 31 shows the main components of the mobile terminal shown in FIG. 29 in detail. The main components of the mobile terminal 2900 shown in FIG. 29 will be described in detail with reference to FIG.

The location engine shown in FIG. 31 manages the position and direction information determined by the IPS (Indoor Positioning System) and the 9-axis sensor. In addition, position management manages position information of devices to be controlled and shape information of each device.

A device selection engine manages a scan zone and a LOS / NLOS mode selection related information for selecting a device to be controlled. Also, the device management includes information such as communication path information of each device or a device icon, and is applicable to a virtual object instead of the device.

Network management controls communication connection with anchor devices, gateways, cloud servers, etc., and controls the transmission / reception of data / commands with each device in conjunction with communication path information in the device management described above. .

Figure 32 shows the management server shown in Figure 29 in more detail. 32, the main components of the management server 2920 shown in FIG. 29 will be described in detail.

Communication with the location system 3210, the smart home solution server 3220 and the management server 3230 is performed via the connectivity module of the mobile terminal 3200. [

In particular, the management server 3230 includes an application, a device icon DB, a device mapping shape DB, a device connection path DB, and a location / configuration management DB. The application performs common web, media, and control functions.

The device icon DB (Device Icon DB) includes a graphic image of an icon identifying a device to be controlled. The Device Mapping Shape DB includes a graphic image for identifying a rough shape of a device to be controlled or a menu for controlling the device.

The Device Connection Path DB includes information on a communication method (e.g., a cloud, a gateway, an IR, an Alljoy, etc.) between a device to be controlled and a mobile terminal. Also, the Position & Configuration Management DB includes absolute / relative position information of the devices to be controlled.

Accordingly, when registering the position of the specific device to be controlled, the mobile terminal 3200 may download the shape-related graphic image of the specific device from the management server 3230, May be uploaded to the management server 3230. For example, in the uploading process, an image of a specific device taken by the mobile terminal 3200 may be used.

Further, since the icon of each device is stored in the management server 3230, when the mobile terminal 3200 points to a specific device, it is possible to display the corresponding icon through communication with the server 3230. [

Also, communication connection information between the device to be controlled and the mobile terminal is uploaded or downloaded between the mobile terminal 3200 and the management server 3230.

33 schematically shows a process of registering a location of a device located in a room using a mobile terminal according to an embodiment of the present invention. The mobile terminal 3310 and the management server 3330 shown in FIG. 33 include all or some of the functions of the above description. In order to apply an embodiment of the present invention, a process of registering a specific device to be controlled among the devices located in the room is required.

33, it is assumed that a mobile terminal 3310 according to an embodiment of the present invention and a specific device 3320 to be controlled are adjacent to each other. There is no restriction on the specific device 3320, and it is applicable even to a legacy device. The legacy device corresponds to, for example, an analog TV that does not have a communication function or is not a digital type.

At this time, as shown in Fig. 33, on the screen of the mobile terminal 3310, some information necessary for registration is displayed. For example, a device list for determining the type of the specific device 3320 to be controlled is output. If there is no information corresponding to the specific device 3320 in the list, the management server 3330 is designed to request related information. Further, the mobile terminal 3310 sets a separation distance for controlling the specific device 3320. However, if the distance exceeds the maximum range in which the mobile terminal 3310 can control the specific device 3320, a warning message for re-adjustment may be displayed.

When the input of the above two conditions (device identification information, controllable separation distance) is completed, the mobile terminal 3310 transmits the related information to the management server 3330. The management server 3330 accesses the internal DB to extract device mapping shape information, device icons, device communication connection path information, and the like. Then, the extracted information is transmitted from the management server 3330 to the mobile terminal 3310.

On the other hand, an arrow indicator is displayed on the top of the screen of the mobile terminal 3310 of FIG. For example, if the mobile terminal 3310 points to the device 3320 to be controlled, but is out of the controllable range, it may be used as an indicator to redirect the direction.

FIG. 34 is a diagram illustrating a case where devices to be controlled are present in different areas of a room. As described above, according to an embodiment of the present invention, the absolute position of each device located in a room can be determined using an anchor device (or a reference device and a naming card) to which an IPS is applied. Further, as shown in FIG. 30, information about the relative positions of the respective devices (for example, in the living room or inside the room) can also be shared.

For example, as shown in FIG. 34, the B device 3420 is located in the living room 3420 and the A device 3410 is located in the inside of the living room 3401. It is assumed that the A device 3410 or the B device 3420 is controlled by the mobile terminal 3400 according to an embodiment of the present invention.

If the relative location information of each device, which is one of the features of the present invention, can not be shared, the mobile terminal 3400 can determine that the A device 3410 and the B device 3420 are located in completely different zones none. In particular, when the A device 3410 and the B device 3420 are adjacent to each other, a problem is likely to occur. However, according to one aspect of the present invention, since the mobile terminal 3400 shares the relative location information, it is possible to control the B device 3420 located in the different area from the A device 3410 in the area where the mobile terminal 3400 is located . Solutions for solving the problem expected in Fig. 34 will be described later with reference to Fig. 35 and the like below.

Fig. 35 shows a first embodiment for overcoming the problem in the case of Fig. Figure 35 is an embodiment of the LOS (Line Of Sight) mode in the situation illustrated in Figure 34; More specifically, the LOS mode refers to a mode in which only a controllable device-related information visible to a user is provided by the mobile terminal according to an embodiment of the present invention, Only information on possible devices is provided by a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 35A, the mobile terminal 3500 according to an embodiment of the present invention and the A device 3510 to be controlled (pre-registered) are located in the same area. On the other hand, the B device 3520 is located in a different area from the A device 3510, and a wall exists between the A device 3510 and the B device 3520. Therefore, the B device 3520 can not be visually recognized from the viewpoint of the user holding the mobile terminal 3500. However, as described above, the mobile terminal 3500 can recognize both the A device and the B device by using the location information or the like, and can further recognize the relative positions of the respective devices 3510 and 3520 (e.g., ). In addition, both the A device 3510 and the B device 3520 can be recognized according to the pointing direction and the distance measurement of the mobile terminal 3500. [

However, since the LOS mode is assumed in FIG. 35, it is not necessary to display the B device in the invisible area to the user. 35 (b), the mobile terminal 3501 outputs only a graphic image necessary for controlling the A device 3510. [ Assuming that the A device 3510 is a TV, the graphic image 3501 shown in FIG. 35B includes options (ex: channel up / down, volume up / down Etc.).

Fig. 36 shows a second embodiment for overcoming the problem in the case of Fig. FIG. 36 is an embodiment of a Non Line Of Sight (NLOS) mode in the situation illustrated in FIG. More specifically, the NLOS mode herein refers to a mode in which a mobile terminal according to an embodiment of the present invention provides information not only to a controllable device visible to a user but also to devices not shown, The information related to the invisible devices as well as the controllable devices belonging to the same area as the mobile terminal is also provided by the mobile terminal according to an embodiment of the present invention.

As shown in FIG. 36 (a), the mobile terminal 3600 according to an embodiment of the present invention and the A device 3610 to be controlled (registered) are located in the same area. On the other hand, the B device 3620 is located in a different area from the A device 3610, and a wall exists between the A device 3610 and the B device 3620. Therefore, the user who holds the mobile terminal 3500 can not visually confirm the B device 3520, but may also need to control peripheral devices not belonging to the same area.

In contrast to Fig. 35, Fig. 36 needs to display even the B devices in the invisible area to the user since the NLOS mode is assumed. 36 (b), the mobile terminal 3601 outputs all of the graphic images necessary for controlling the A device 3610 and the B device 3620. [ Assuming that the A device 3610 is a TV and the B device 3620 is a refrigerator, the graphic image 3601 shown in FIG. 36B includes options (ex : Channel up / down, volume up / down), and options for controlling the refrigerator (ex: refrigerator power on / off, temperature control, etc.). That is, it is also possible to display an icon for identifying the device located on the path in the direction of the pointing direction of the mobile terminal, and further display the perspective view according to the distance between the mobile terminal 3600 and the A device and the B device, Belongs.

35 (a) and 35 (b), when the mobile terminal 3500 is set to correspond to the LOS mode entry and the action to make the mobile terminal 3500 horizontal with the ground, An action to be vertical may be set to correspond to the NLOS mode entry. It can be realized by using a 9-axis sensor or the like, and it is also within the scope of the present invention to implement it by motion, touch signal, key input or the like other than the rotation angle.

FIG. 37 shows a third embodiment for overcoming the problem in the case of FIG. Fig. 37 can be applied to the contents described in Fig. However, it is assumed that the specific area to which each of the A device and the B device shown in FIG. 37 (a) belong is not set.

37 (a), both the mobile terminal 3700 according to the embodiment of the present invention and the A device 3710 and the B device 3720 to be controlled are registered in the wall 3730 ). However, the mobile terminal 3700 can calculate the distance to each device based on the location information of each device.

At this time, FIG. 37 assumes the LOS mode, and the user of the mobile terminal 3700 may find it difficult to recognize a relatively distant B device, and may only want to control the A device (i.e., the closest device). 37B, the mobile terminal 3701 outputs only the graphic image necessary for controlling the nearest A device 3710. [

Fig. 38 shows a fourth embodiment for overcoming the problem of Fig. Fig. 38 can be applied to the contents described in Fig. However, it is assumed that the specific area to which each of the A device and the B device shown in FIG. 38A belong is not set.

As shown in FIG. 38A, both the mobile terminal 3800 according to an embodiment of the present invention and the A device 3810 and the B device 3820 to be controlled (pre-registered) ). However, the mobile terminal 3800 can calculate the distance to each device based on the location information of each device.

38 assumes the NLOS mode, and the user of the mobile terminal 3800 is not able to recognize the relatively far-located B device, but can also control the A device (i.e., the nearest device) as well as the relatively far- can do. Thus, as shown in Figure 38 (b), the mobile terminal 3801 outputs all of the graphical images required to control the nearest A device 3810 and the relatively farther B device 3820.

39 is a diagram for explaining a range in which a mobile terminal according to an embodiment of the present invention can select a device to be controlled and a range in which a device to be controlled can be recognized. As described above, according to an embodiment of the present invention, it is possible to select a specific device according to the pointing direction of the mobile terminal. Hereinafter, FIG. 39 is intended to define two ranges that the mobile terminal can recognize according to an embodiment of the present invention.

As shown in FIG. 39, the mobile terminal according to an embodiment of the present invention includes a range (a) for selecting a specific device and a range (b) for recognizing a device to be displayed on the screen of the mobile terminal .

Therefore, although an icon identifying a plurality of devices recognized in FIG. 39 (b) is displayed on the screen of the mobile terminal, it is a feature of the present invention that the specific device recognized in (a) is highlighted and displayed. This will be described later with reference to FIGS. 40 to 42. FIG.

FIG. 40 shows an example of a graphic image outputted by a mobile terminal according to an embodiment of the present invention when there are a plurality of devices to be controlled which can be recognized in FIG.

As shown in FIG. 40, the mobile terminal 4000 displays icons 4010, 4020, 4030, and 4040 that identify each of all the devices recognized in the range b of FIG. In particular, it is also possible to highlight and display the icon 4010 corresponding to the specific A device recognized in the range a in Fig. The icons may be stored in a management server or the like, or may correspond to image data photographed using a camera of a mobile terminal. Furthermore, the positions and sizes of the icons shown in FIG. 40 are designed in consideration of the difference in actual distance from the mobile terminal 4000 and the like.

FIG. 41 shows another example of a graphic image outputted by a mobile terminal according to an embodiment of the present invention when there are a plurality of devices to be recognized as control targets in FIG.

As shown in FIG. 41, the mobile terminal 4100 displays icons 4110 and 4120, which identify each of all devices recognized in the range b of FIG. In particular, it is also possible to highlight and display the icon 4110 corresponding to the specific A device recognized in the range a in Fig. Compared with FIG. 40, however, there is a difference that FIG. 41 shows icons of the same size without considering the actual positions of the respective devices. On the other hand, although not shown in Figs. 40 and 41, referring to the access history of the devices to be controlled, at least one of sizes or positions of icons (corresponding to each device) displayed on the mobile terminal is changed Are also within the scope of the present invention.

FIG. 42 shows another example of a graphic image output by the mobile terminal according to an embodiment of the present invention when there are a plurality of devices to be recognized as control targets in FIG. 40 actually represents the position of each device as realistically as possible, and Fig. 41 determines the size of each device evenly without any consideration.

On the other hand, Fig. 42 is an embodiment more suitable for user convenience. That is, as shown in FIG. 42, the mobile terminal displays the icon 4210 corresponding to the specific device recognized in the range a in FIG. 39 at a predetermined position. That is, although the actual position of each device is not considered, it is based on what is recognized in the range a in FIG. It is also within the scope of the present invention to design the predetermined position to be located at the center of the screen of the mobile terminal 4200, unlike FIG.

Furthermore, it is possible to design the icons 4230 and 4220 indicating other devices to remain in the inactive state so that the user can not select them. In addition, although it is possible to visually show that the specific A device 4210 has been selected, it is also possible to output audio data (alarm) or to cause the vibration to be executed, thereby informing the user that the specific A device 4210 has been selected There is a number.

It is also within the scope of the present invention to design not only the mobile terminal 4200 but also the selected A device 4210 itself to output the pad back signal, though it is not shown in FIG. For example, when the A device 4210 corresponds to a lamp, it is pre-set to blink temporarily.

FIG. 43 shows an example of a graphic image output by the mobile terminal according to an embodiment of the present invention when a plurality of devices to be controlled exist in the same area of a room.

In the previous figures 40 to 42, it has been described that the specific device recognized in the range a in FIG. 39 is highlighted and displayed. 43 and 44, it is also possible to output a graphic image irrelevant to that recognized in the range a of Fig.

As shown in FIG. 43 (a), the mobile terminal 4300 recognizes a plurality of devices 4310, 4320, and 4330. This is determined based on the range b described in FIG.

43 (b), the mobile terminal 4300 differentially displays the icons corresponding to the recognized devices. First, the C device 4331 corresponds to the device that the user has controlled immediately before, or corresponds to the device that accessed the most or the device that has controlled the longest time. On the other hand, the A device 4311 corresponds to the device that has accessed the second-most-frequently accessed device or the device that has been controlled for the second longest time. The B device 4321 corresponds to the device that has the least amount of time control or corresponds to the least accessed device. Namely, according to the above criterion, as shown in FIG. 43 (b), the size of the icon corresponding to each device is designed to be automatically changed differently.

Fig. 44 shows another example of Fig. In particular, FIG. 43 (a) is assumed.

44, the mobile terminal 4400 according to the embodiment of the present invention includes an icon 4431 for displaying the C device, an icon 4411 for displaying the A device, an icon (for displaying the B device 4421). This changes the display order according to the actual distance of the mobile terminal 4400 and each device.

45 shows an example of a graphic image outputted by the mobile terminal according to an embodiment of the present invention when there are devices to be controlled in different areas of the room (in particular, when height information is different) .

It is assumed that the mobile terminal 4500 is located in a two-story building, as shown in Figure 45 (a). A C device 4530 and a D device 4540 are located on the first floor and an A device 4510 and a B device 4520 are located on the second floor. As described above, since the three-dimensional position information of each device is recorded, the mobile terminal 4500 is also located on a different layer from the device located on the same layer as the mobile terminal 4500 through communication with the anchor device and the management server It is possible to distinguish devices. In particular, it is assumed that the mobile terminal 4500 exists on the second floor.

At this time, there are two ways in which the mobile terminal 4500 can display icons corresponding to controllable devices. One is the LOS mode and the other is the NLOS mode.

Particularly, Figure 45 (b) shows an embodiment of the LOS mode. The mobile terminal 4500 displays the A device correspondence icon 4511 and the B device correspondence icon 4521 that exist in the same layer as the second layer where the mobile terminal 4500 is located. Therefore, the user can use the mobile terminal 4500 to check and control only devices in his / her line of sight.

On the other hand, FIG. 45C shows an embodiment for the NLOS mode. That is, the mobile terminal 4500 displays not only the A device correspondence icon 4512 and the B device correspondence icon 4522 of the currently located layer (second layer) but also the C device correspondence icon 4532 of the other layer (first layer) D device corresponding icon 4542 is displayed. Accordingly, the user can use the mobile terminal 4500 to display not only the devices in his / Devices can also be identified and controlled.

FIG. 46 is a diagram for explaining a process of automatically correcting a position error in a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 46, the mobile terminal 4600 may generate a slight position error due to the movement of the user. A method of setting a scan zone of the mobile terminal 4600 in order to reduce the position error occurring as described above will be described.

A method of setting the scan zone according to Equations 1, 2, and 3 will be described.

1 은 커지고, 따라서, 이동 단말기와 가까이 있는 타겟을 포인팅할 경우, 회전각이 커져서 오류가 발생할 가능성이 높다.Here, De is a value fixed by an IPS (Indoor Positioning System) system. As r becomes shorter

1 becomes large, and therefore, When the target is pointed, the rotation angle becomes large and the error is likely to occur.

In order to solve such a problem, it is desirable to set the default scan width used for scanning of the mobile terminal to be equal to or larger than the position error of the IPS system. It is also preferable to set the position size of the target device to the default value. Therefore, even when there is an angle (angle) error, the case of mistaking the target device can be reduced. Furthermore, when there are a plurality of adjacent targets, the display is designed to be displayed on the screen of the mobile terminal.

FIG. 47 shows a scenario in which a mobile terminal according to an embodiment of the present invention is used indoors. FIG. 47 shows a method of controlling a plurality of devices located in a room using a mobile terminal.

It is assumed that there are three IPS anchor devices 4710 in the room. Accordingly, the position of the mobile terminal 4700 and the respective devices can be known in advance. For example, location information of a lamp, a TV, a refrigerator, a robot cleaner, an air conditioner, a washing machine, and the like is registered in advance using the mobile terminal 4700 and the IPS anchor devices 4710 and stored in a mobile terminal or a management server.

Furthermore, as described in the previous drawings, it is also possible to set a virtual object according to the position and direction (pointing) of the mobile terminal although it does not actually exist. For example, in the bedroom, information indicating that the mobile terminal 4700 has been pointed in a particular direction (e.g., direction to the ceiling) and corresponding commands (e.g., sleep mode 4730, light off) The light is automatically turned off when the mobile terminal 4700 points from the same location (bedroom) to the ceiling. In other words, there is no need to point to a light that is an actual device.

As another example, in the living room, information that the mobile terminal 4700 has been pointed in a particular direction (e.g., direction to the ceiling) and corresponding commands (e.g., virtual post-it mode 4720, When the mobile terminal 4700 is mapped and stored in advance in the management server, when the mobile terminal 4700 points from the same position (living room) to the ceiling, a certain message is automatically displayed. In other words, there is no need to check a certain message attached to the actual refrigerator in front of the refrigerator.

When the mobile terminal 4700 is pointing in one direction, both the air conditioner 4750 and the washing machine 4760 included in the scan zone can be recognized. Of course, since the washing machine 4760 is located in the room 2, not in the living room in which the mobile terminal 4700 is located, the user can not directly see it. However, since the mobile terminal 4700 has position information of the respective devices, It can be determined that not only the air conditioner 4750 but also a washing machine 4760 in another area exists in the scan zone.

FIG. 48 is a view schematically illustrating components of a mobile terminal according to an embodiment of the present invention. With reference to the previously described figures, those skilled in the art will be able to supplement the interpretation of FIG. 48, and it is obvious that the subject matter of the present invention is to deleting some modules and to implement the present invention.

48, the mobile terminal 4800 includes a communication module 4810, a memory 4820, a controller 4830, a sensing module 4840, a display module 4850, and the like.

The communication module 4810 initiates a communication connection with a plurality of reference devices for a location service, and the memory 4820 registers information for identifying a device to be controlled.

The controller 4830 determines whether or not at least one of the devices registered in the memory 4820 belongs to a specific group based on the position and orientation information of the mobile terminal 4800 and the location information of the device registered in the memory 4820 Generates a graphic image corresponding to one device, and the display module 4850 displays the generated graphic image in a predetermined area.

According to another embodiment, the controller 4830 maps devices belonging to a position corresponding to the direction information of the mobile terminal 4800 into a specific group. The direction information means, for example, a direction in which one side of the mobile terminal 4800 is pointing. Further, the specific group includes a first sub group to which devices belonging to a position corresponding to the position information of the mobile terminal belongs or a second sub group to which devices belonging to positions that do not correspond to the position information of the mobile terminal belong . For example, compartmentalized location information (e.g., a living room, a living room, a toilet, etc.) in a room may be used as group information.

According to another embodiment, when the first action of the mobile terminal is detected by the sensing module 4840, the controller 4830 regards only the first subgroup as the specific group, When the second action of the mobile terminal is detected by the controller 4840, the controller 4830 regards only the second subgroup as the specific group. The sensing module 4840 may be implemented as a 9-axis sensor, for example.

When there are a plurality of devices belonging to the specific group, the controller 4830 accesses the memory 4820 to obtain usage history information, and according to the acquired information, displays a graphic image corresponding to each device For example, change the size of the icon).

The communication module 4810 transmits at least one of ID or location information identifying the device to the server and receives at least one of an icon or a communication connection method indicating the device from the server. The server corresponds to, for example, the above-described management server.

The direction information of the mobile terminal 4800 may be designed to be determined according to a point where one side of the mobile terminal sensed by the sensing module 4840 points.

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

A method of controlling a mobile terminal according to an exemplary embodiment of the present invention includes starting communication connection with a plurality of reference devices for a location service (S4910), registering information for identifying a device to be controlled in a memory A graphic image corresponding to at least one device belonging to a specific group among the devices registered in the memory is generated based on the position / direction information of the mobile terminal and the position information of the device registered in the memory in step S4920 (S4930), and displaying the generated graphic image in a predetermined area (S4940).

According to another embodiment of the present invention, the generating step (4930) further includes mapping devices belonging to a position corresponding to the direction information of the mobile terminal to a specific group.

According to another embodiment of the present invention, when the first action of the mobile terminal is detected by the sensing module in the mobile terminal, only the first subgroup is regarded as the specific group, Module, when the second action of the mobile terminal is detected, the second subgroup is designed to be regarded as the specific group. 35 and 36 in detail.

According to another embodiment of the present invention, the step (S4920) of registering the device to be controlled in the memory includes transmitting at least one of the ID or location information identifying the device to the server, , An icon representing the device, or a communication connection scheme.

Meanwhile, the above-described technical contents in the previous drawings 1 to 49 are also applicable to the IPS (Indoor Positioning System) of the triangulation technique. For reference, the biggest disadvantage of the GPS (Satellite Positioning System) is that it does not work in a room that does not receive satellite signals. For example, if you have a smartphone with a built-in GPS function, you can go to the front gate of a large shopping mall, but you can not find a specific store or toilet in the shopping mall. In order to solve such a problem, the system introduced is an indoor positioning system (IPS).

IPS technologies using technologies such as UWB (Ultra WideBand), Wi-Fi, and Bluetooth have adopted a triangulation method for location measurement in most cases. The triangulation method is performed using an anchor device (or a reference device) serving as a position reference point and a mobile device to be measured.

Typically, three or more reference devices are required to be position reference points for two-dimensional position measurement, and four or more reference devices are required for three-dimensional position measurement.

However, in the case of applying the algorithm of Angle Of Arrival (AOA), at least two reference devices are required, and the present invention described later in FIG. Furthermore, even when there is one reference device, it is possible to set the origin reference device by pointing the mobile terminal toward the reference device.

On the other hand, the reference devices need to know their position coordinates with respect to the reference point so that the unique positional relationship between the mobile terminal and the reference device can be confirmed. Thus, according to the prior art, physical measurements have to be made to acquire the position information of each of the reference devices. The related problems will be described later in more detail in Fig. 50 and Fig.

On the other hand, according to the present invention to be described later in the specification, it is possible to set the position coordinates of the reference devices more quickly by using the six-axis or nine-axis sensor of the mobile terminal. 52 to 59 will be described later in detail.

50 is a diagram schematically showing an IPS (Indoor Positioning System) based on triangulation. 50 assumes that four reference devices (or anchors or anchor devices) are required for three-dimensional (3D) position measurements. Of course, as described above, for a two-dimensional (2D) position measurement, three reference devices are sufficient.

As shown in FIG. 50, the coordinates of the reference devices 5010, 5020, 5030, and 5040 used in the IPS must be determined in order to determine the location of the mobile terminal 5000 located at home. According to the related art, there is a problem in that a user or an expert must input position coordinate values after actually measuring the position of each of the reference devices.

For example, after the position of each of the reference devices is directly measured by a user or an expert, the position reference value (x1, y1, z1) of the first reference device 5010 is stored in the memory, (X3, y3, z3) of the third reference instrument 5030 is stored in the memory, and the position coordinates of the fourth reference instrument 5040 (x2, y2, z2) The coordinate values (x4, y4, z4) must be stored in memory. Therefore, there is a problem that accuracy is lowered and unnecessary time is required. Of course, each of the reference devices may be able to measure the distance by communicating with other reference devices, but also in this case. With reference to FIG. 51, description will be made in detail.

FIG. 51 is a view for explaining the conventional triangulation-based IPS problem shown in FIG. As described above, it is assumed that the distance between each reference devices is calculated by communication between the reference devices.

However, when there is no coordinate information of the reference devices, there is a problem that the direction in which the reference devices are located can not be accurately known from the position of the mobile terminal. In particular, since the position of the reference device and the position of the mobile terminal become relative positions, the image formed by the reference devices by the distance information is actually the same as in FIG. 51 (a) or formed by the mirror plane (b).

Further, when there is no coordinate value of each reference device, the mobile terminal can not determine the second angle formed with the first angle and the x-axis that the mobile terminal makes with the z-axis, and also the rotation information according to the first angle and the second angle There is a problem that it can not be judged.

Due to the above-described problems, there is a strong demand for a solution capable of easily and quickly setting the location information of the reference devices in the IPS environment by non-experts. Hereinafter, this will be described later with reference to Figs. 52 to 59.

52 is a block diagram illustrating a mobile terminal according to another embodiment of the present invention.

As shown in FIG. 52, the mobile terminal 5200 is designed to communicate with the position calculation module 5210 and the IPS reference devices 5220. The location calculation module 5210 calculates the location of the mobile terminal 5200 and the reference devices 5220 in the IPS environment and may be implemented as an independent entity such as a gateway or a server, Or may be included in the mobile terminal 5200.

The mobile terminal 5200 according to another embodiment of the present invention includes a user interface 5201, an anchor position configuration module 5202, an IPS module 5203, a motion blending module 5204, and the like. The IPS module 5203 includes, for example, UWB, Bluetooth, WiFi, and the like. The motion mixing module 5204 is composed of, for example, a six-axis sensor or a nine-axis sensor. The 6-axis sensor includes an acceleration sensor for recognizing the motion in the space and a geomagnetic sensor for detecting the direction. The 9-axis sensor includes not only the characteristics of the 6-axis sensor but also the tilt sensor.

The geomagnetic sensor is designed, for example, to recognize the azimuths of north, south, east and west, and the tilt sensor is designed to recognize the mobile terminal being turned or laid down, and the acceleration sensor is designed to recognize shaking or moving the mobile terminal .

Thus, it is possible for the mobile terminal 5200, including the modules shown in Figure 52, to calculate the location of the reference devices 5220. [ The reference devices 5220 can communicate with each other and can perform distance measurement between TOA (Time Of Arrival), TOF (Time Of Flight) and RSSI. 52 will be described with reference to the flowchart of FIG. 53. FIG.

Meanwhile, the TOA (Time Of Arrival) and the triangulation method described in this specification will be described in more detail as follows.

The TOA method is a method of measuring the propagation time between the mobile device and the fixed device to obtain the distance. TOA can be calculated synchronously or asynchronously. In synchronous mode, the receiver and beacon are synchronized in time, and the beacon sends a signal to the receiver, recording the absolute current time. Since the time is synchronized between the receiver and the beacon, the receiver can measure the reception time of the signal and obtain an absolute time to reach the signal during the beacon and reception period. Therefore, the distance from the known signal transmission rate and signal arrival time can be obtained. In the asynchronous mode, there is no need to synchronize the time between the receiver and the beacon. The beacon records the current time and immediately signals the receiver. The receiver sends back the signal received from the beacon back to the beacon. If the receiver has a constant delay to send the signal back to the beacon, the beacon can calculate the distance between the beacon and the receiver from the difference between the transmission time and the reception time of the signal and the delay time at the receiver. TWR is a technique that enables round-trip time-of-flight (TOF) measurements of signals between two asynchronous receivers.

TWR distance measurement technology is a technique to measure the distance from the transmitter through the radio wave transmission time and the propagation velocity arriving at the receiver. It is a distance measurement technique with higher accuracy than conventional RSSI-based technology, based on actual RF propagation, which is about 900,000 times faster than ultrasound velocity. The above-described techniques can be applied between reference devices or between a reference device and a mobile terminal.

The position estimation by the triangulation method is a method of estimating the position of the mobile terminal by calculating the distance between three or more reference points (reference device or anchor device) already known coordinates and the mobile terminal. The distance between the reference point and the mobile terminal is calculated using a propagation characteristic value such as RSSI.

53 is a flowchart showing a control method of a mobile terminal according to another embodiment of the present invention. 53 describes a method for more accurately calculating the positions of the reference devices which have not been confirmed in the previous FIG. Particularly, step B shown in FIG. 53 is a main feature of the present invention, and it is another feature of the present invention to improve the technical effect of the present invention by adding step C and the like.

First, the main steps (steps A, B, and C) shown in FIG. 53 will be outlined as follows.

The step A shown in FIG. 53 is a step of finding the distance between the reference devices shown in FIG. Each of the reference devices can measure the distance between the reference devices via Time Of Flight (TOF) or RSSI algorithms. After step A is completed, a polyhedron composed of the reference devices is determined as shown in (b) of FIG.

53 is a step for removing the image by the mirror plan shown in FIG. 51 and finding the rotation angles of the respective reference devices with respect to the horizontal plane and the magnetic north direction in the gravity direction. The step B may be implemented using a six-axis sensor or a nine-axis sensor of the mobile terminal.

If the resultant value of step B shown in FIG. 53 is within a predetermined error range, step C may be omitted. However, step C is a step for more accurately correcting the rotation angle with respect to the horizontal plane in the gravity direction. For example, if the distance between each reference device is too far away, or if each reference device is not within the LOS (Line Of Sight) range, then step C is needed to compensate for the accuracy of step B.

53, the order of operations is not limited to the alphabetical order, and it is naturally also within the scope of the present invention to modify the order in some order. Each of the steps shown in FIG. 53 will be described in more detail below.

As shown in FIG. 53, it is assumed that a plurality of reference devices in the home are installed (S5310). The network is set up so that each of the reference devices and the mobile terminal can communicate with each other (S5320).

Step A (S5330) shown in FIG. 53 includes steps S5331 and S5332, which will be described in more detail with reference to FIG. The mobile terminal (IPS Mobile Device) executes the anchor location configuration function (S5331). The anchor position configuration function corresponds to a command for obtaining coordinate values of reference devices. Further, the reference device (or the anchor device) measures the distance through communication with each other (S5332).

Step B (S5340) shown in FIG. 53 includes steps S5341, S5342, S5343, and S5344, and will be described in more detail below with reference to FIG. An arbitrary reference device is selected using the mobile terminal (S5341). The mobile terminal is pointed to the direction in which the reference device selected in step S5341 is located (S5342).

At this time, the mobile terminal stores the distance between the mobile terminal and the reference device in the memory by using the TOF or RSSI algorithm, and further stores the information sensed by the 6-axis sensor or the 9-axis sensor in the memory (S5343 ). That is, it is possible to obtain the direction-related information of each of the reference devices based on the information sensed by the six-axis or nine-axis sensor of the mobile terminal and the distance information.

Finally, another feature of step B is step S5344. It is possible to estimate the positions of all the reference devices without repeating steps S5341 to S5343 for all the reference devices.

If the number of reference devices located in the home is an even number, repeat steps S5341 to S5343 only for the reference devices ((total number of reference devices / 2) + 1) or more reference devices, and perform the steps for the remaining reference devices no need. On the other hand, if the number of the reference devices located at home is an odd number, it is necessary to repeat steps S5341 to S5343 only for the reference devices (total number of reference devices / 2) or more and perform the steps for the remaining reference devices none. This is because it assumes that the distance information between the respective reference devices is already known.

Step C (S5350) shown in FIG. 53 will be described in more detail with reference to FIG. Step C may be understood as another embodiment of the present invention.

Based on the data collected through steps S5310 to S5350 described above, a position is set for each of the reference devices (S5360).

Further, the mobile terminal is positioned at a position in the vertical direction on the ground in any reference device. The distance between the reference device and the mobile terminal located on the ground is calculated, and an offset of the height of the reference device is applied (S5370). In this regard, it will be described in more detail below with reference to FIG.

The location information for each reference device determined through steps S5310 to S5370 is shared with other mobile terminals or devices through the location calculation module 5210 shown in Fig. 52 (S5380).

FIG. 54 is a view for supplementarily explaining step A shown in FIG.

As shown in FIG. 54A, before performing the step A of FIG. 53, since the reference device 5410 can not know the distance to other reference devices, the tetrahedron formed by the plurality of reference devices may be estimated at all I can not. Therefore, there is a problem that the mobile terminal 5400 can not know the position of the reference device at all.

On the other hand, when step A of FIG. 53 is performed, the reference device 5411 learns information on the relative distance with respect to other reference devices, as shown in FIG. 54 (b). Therefore, as shown in FIG. 54 (b), a virtual tetrahedron formed by the home reference device 5411 in which the mobile terminal 5401 is located is determined. However, at this time as well, the mobile terminal 5401 can accurately locate the reference device 5411 only by the distance information between the reference devices (i. E. No direction information because there is no information about the rotation) There is an unknown problem.

FIG. 55 is a view for supplementing the step B shown in FIG.

The step (a) in Figure 55 corresponds to the step (b) in Figure 54. That is, the reference device 5510 shown in FIG. 55A can know the distance to other reference devices, but the mobile terminal 5500 does not have direction information for each reference device.

55 (b), the mobile terminal 5501 points to an arbitrary reference device 5511, and uses the 6-axis / 9-axis sensor in the mobile terminal 5501 to measure the gravity direction and the magnetic north You can see the rotation status of the reference device relative to the direction. That is, the image is removed by the mirror plan shown in FIG.

Finally, as shown in (c) of FIG. 55, since the mobile terminal 5502 also has information on the direction as well as the distance to the reference device 5512, the image by the mirror plan shown in FIG. 51 There is an advantage that the actual object can be confirmed.

On the other hand, if the accuracy of the 6-axis or 9-axis sensor included in the mobile terminal 5502 is high, since the error is small, the image determined in Figure 55 (c) and the actual object are almost the same. However, when the accuracy of the information by the above-described six-axis or nine-axis sensor is relatively low, the image shown in Figure 55 (c) may be slightly rotated unlike the actual object. To solve such a problem, a process (step C of FIG. 53) described later in FIG. 56 is required.

56 is a view for supplementarily explaining the step C shown in Fig. As described above, when the error is over a predetermined range after performing the B step, it is designed to perform the C step.

56 (a) shows the state of (b) in FIG. 55, and it is assumed that the reference device 5610 and the mobile terminal can communicate with each other. 56 (b), the reference device 5611 maintains the fixed state, while the mobile terminal 5601 maintains the fixed height at the ground level, and further maintains the horizontal state Is designed. For example, when the mobile terminal 5601 forms an arbitrary plane (dotted line) as shown in Figure 56 (b), it must be parallel to the ground or the horizontal plane, so that the angles As shown in Fig. Therefore, the angles between the mobile terminal 5602 and the reference device 5612 are adjusted as shown in (c) of FIG.

That is, when the comparison between FIG. 56 (b) and FIG. 56 (c) is made, the closed curve formed by the mobile terminal is adjusted to be perfectly horizontal with the ground. Although the plane formed by the mobile terminal is shown as a closed curve of a quadrangle in FIG. 56, other shapes representing a horizontal plane can be modified and designed, and this also falls within the scope of the present invention.

FIG. 57 is a view for supplementing the step S5370 shown in FIG. Figure 57 (a) corresponds to Figure 56 (c). However, as shown in FIG. 57 (a), the mobile terminal 5700 is likely to collect data including a slight error with respect to the height information of the reference device 5710. In order to solve such a problem, Figure 57 (b) is presented.

That is, as shown in FIG. 57 (b), the mobile terminal 5701 is placed on the ground. In particular, the mobile terminal 5701 is positioned at a point where the reference device 5711 touches the ground vertically. Therefore, the distance between any specific reference device 5711 and the mobile terminal 5701 is measured, and an offset to the height from the ground is applied.

In the previous drawings, it is assumed that there are at least three or four reference devices. On the other hand, if there is only one reference device, the reference device is pointed by using the mobile terminal including the 9-axis sensor to record the reference device at a position relative to the magnetic field north direction on the basis of the mobile terminal, It can also be used in conjunction with other positioning systems, such as fingerprinting. Even when two reference devices exist, it can be implemented by applying an indoor positioning algorithm of the AOA (Angle Of Arrival) method.

Meanwhile, when a user having a terminal capable of communicating with the AP enters the environment in which the AP is installed, the fingerprint method confirms the signal strength from the AP and transmits a reference point (RP) Or a reference device), and estimates the RP having the most similar characteristics as the position of the user.

This method is divided into a training step in which the signal characteristics are acquired in a predetermined area and stored in the DB, and a positioning step in which the position of the object is determined based on the training step. There is a disadvantage in that it is necessary to set up a zone in advance of the positioning and to recognize the signal characteristics in each zone and then store it in the DB and perform this process every time the environment of the positioning zone is changed. However, Since the environmental information is reflected in the positioning, it is advantageous in that it is less constrained by the surrounding environment than the existing model-based positioning method and has excellent position accuracy.

The fingerprint data stored in the DB to determine the location using the fingerprint method may be divided into a deterministic fingerprint method and a stochastic fingerprint method, depending on which data is used or how the data is used in the positioning.
