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 or absence of an object approaching a predetermined detection surface or an object existing nearby without mechanical contact by using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner area of the mobile terminal covered by the touch screen described above or in the vicinity of 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 capacitance type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. If the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of a conductive object as a change in electric field according to the proximity of the object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, an action of approaching a touch screen without contacting an object to recognize that the object is located on the touch screen is referred to as a "proximity touch", and the touch An act of actually touching an object on a screen is called a "contact touch". The location at which an object is proximity-touched on the touch screen means a location at which the object corresponds vertically to the touch screen when the object is proximity-touched. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) there is.

Meanwhile, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and proximity touch pattern detected through the proximity sensor 141, and furthermore, visual information corresponding to the processed data. It can be output on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) depending on whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor detects a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. detect

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or capacitance generated in a specific part into an electrical input signal. The touch sensor may be configured to detect a location, area, pressure upon touch, capacitance upon touch, and the like, at which a touch object that applies a touch to the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

As such, 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 then transmits corresponding data to the controller 180. Thus, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or the same control according to the type of the touch object that touches the touch screen (or a touch key provided other than the touch screen). Whether to perform different controls or the same control according to the type of the touch object may be determined according to an operating state of the mobile terminal 100 or an application program currently being executed.

The ultrasonic sensor may recognize location information of a sensing object by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generating source through information detected by the optical sensor and the plurality of ultrasonic sensors. The position of the wave generating source can be calculated using the property that light is much faster than ultrasonic waves, that is, the time for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the location of the wave generating source may be calculated by using light as a reference signal and a time difference between the arrival time of ultrasonic waves.

Meanwhile, looking at the configuration of the input unit 120, the camera 121 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. A photo sensor may be stacked on a display device, and the photo sensor is configured to scan a motion of a sensing target close to the touch screen. More specifically, the photo sensor scans the content placed on the photo sensor by mounting photo diodes and transistors (TRs) in rows/columns and using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing object according to the change in light, and through this, the location information of the sensing object can be obtained.

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 in the mobile terminal 100 or UI (User Interface) and GUI (GraPhic User Interface) information according to such execution screen information. .

Also, the display unit 151 may be configured as a 3D display unit that displays a 3D image. A 3D display method such as a stereoscopic method (glasses method), an auto stereoscopic method (non-glasses method), or a projection method (holographic method) may be applied to the 3D display unit.

According to the method of combining the left and right images into a 3D stereoscopic image, top-down method in which the left and right images are arranged up and down in one frame, left and right images in one frame L-to-R (left-to-right, side by side) method for arranging left and right images, checker board method for arranging pieces of left and right images in tile form, and left and right images in units of columns Alternatively, it is divided into an interlaced method that alternately arranges rows, and a time-sequential, frame-by-frame method that alternately displays a left image and a right image by time.

Also, the 3D thumbnail image may be generated as a single image by generating left and right image thumbnails from the left and right images of the original image frame, respectively, and combining them. In general, a thumbnail refers to a reduced image or a reduced still image. The generated left and right image thumbnails are displayed with a left and right distance difference on the screen by a depth corresponding to the parallax between the left and right images, thereby representing a three-dimensional sense of space.

A left image and a right image necessary for implementing a 3D stereoscopic image may be displayed on a stereoscopic display unit by a stereoscopic processing unit. The stereoscopic processing unit receives 3D images (images at a reference point and images at an extended point of view) and sets left and right images therefrom, or receives 2D images and converts them into left and right images.

The audio output unit 152 may output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like.

It is possible to generate various tactile effects, such as the effect of heat absorption and the effect of reproducing the feeling of coolness and warmth using an element capable of absorbing heat or generating heat.

The haptic module 153 not only transmits a tactile effect through direct contact, but also can be implemented so that a user can feel a tactile effect through a muscle sense such as a finger or an arm. Two or more haptic modules 153 may be provided according to the configuration of the mobile terminal 100 .

The glass-type mobile terminal 400 is configured to be worn on the head of the human body, and may include a frame part (case, housing, etc.) for this purpose. The frame portion may be formed of a flexible material so as to be easily worn. In this figure, it is exemplified that the frame unit includes a first frame 401 and a second frame 402 made of different materials. In general, the mobile terminal 400 may include features of the mobile terminal 100 of FIG. 1 or similar features thereto.

The frame part is supported on the head and provides a space in which various parts are mounted. As shown, electronic components such as a control module 480 and a sound output module 452 may be mounted on the frame unit. In addition, a lens 403 covering at least one of the left eye and the right eye may be detachably mounted on the frame unit.

The control module 480 controls various electronic components included in the mobile terminal 400 . The control module 480 may be understood as a component corresponding to the controller 180 described above. In this figure, it is exemplified that the control module 480 is installed on the frame part on one side of the head. However, the location of the control module 480 is not limited thereto.

The display unit 451 may be implemented in the form of a head mounted display (HMD). The HMD type refers to a display method that is mounted on the head and shows an image directly in front of the user's eyes. When the user wears the glass-type mobile terminal 400, the display unit 451 may be disposed to correspond to at least one of the left eye and the right eye so as to provide an image directly in front of the user's eyes. In this drawing, it is exemplified that the display unit 451 is located in a portion corresponding to the right eye of the user so that an image can be output toward the user's right eye.

The display unit 451 may project an image onto the user's eyes using a prism. In addition, the prism may be light-transmitting so that the user can see the projected image and the general field of view (a range of the user's eyes) together.

As such, an image output through the display unit 451 may be displayed overlapping with a normal field of view. The mobile terminal 400 may provide Augmented Reality (AR), in which a virtual image is superimposed on a real image or a background and displayed as a single image, using the characteristics of the display.

The camera 421 is disposed adjacent to at least one of the left eye and the right eye, and is configured to capture a forward image. Since the camera 421 is positioned adjacent to the eye, the camera 421 may acquire a scene viewed by the user as an image.

In this drawing, the camera 421 is provided in the control module 480 as an example, but is not necessarily limited thereto. The camera 421 may be installed in the frame unit, or may be provided in plural to obtain a stereoscopic image.

The glass-type mobile terminal 400 may include user input units 423a and 423b manipulated to receive a control command. The user input units 423a and 423b may employ any tactile manner, such as a touch or a push, in which a user manipulates them while experiencing a tactile feeling.

When the sound output module 452 is implemented in a bone conduction manner, when the user wears the mobile terminal 400, the sound output module 452 adheres to the head and transmits sound by vibrating the skull.

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

First, communication systems may use different air interfaces and/or physical layers. For example, air interfaces usable by the communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), and Code Division Multiple Access (CDMA). ), Universal Mobile Telecommunications Systems (UMTS) (in particular, Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications (GSM), etc. this may be included.

Hereinafter, for convenience of description, the description will be limited to CDMA. However, it is obvious that the present invention can be applied to all communication systems including orthogonal frequency division multiplexing (OFDM) wireless communication systems as well as CDMA wireless communication systems.

The CDMA wireless communication system includes at least one terminal 100, at least one base station (Base Station, BS (which may also be referred to as Node B or Evolved Node B)), and at least one base station control unit (Base Station Controllers, BSCs). ), and a mobile switching center (MSC). The MSC is configured to connect with the Public Switched TelePhone Network (PSTN) and BSCs. BSCs may be connected in pairs with a BS through a backhaul line. The backhaul line may be provided according to at least one of E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs can be included in a CDMA wireless communication system.

Each of the plurality of BSs may include at least one sector, and each sector may include an omni-directional antenna or an antenna pointing in a specific direction radially from the BS. Also, each sector may include two or more antennas of various types. Each BS may be configured to support multiple frequency assignments, each of which may have a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. BSs may be referred to as Base Station Transceiver Subsystems (BTSs). In this case, one BSC and at least one BS may be collectively referred to as a "base station". A base station may also represent a "cell site". Alternatively, each of a plurality of sectors for a specific BS may be referred to as a plurality of cell sites.

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

In addition, a global positioning system (GPS) may be linked to the CDMA wireless communication system to determine the location of the mobile terminal 100 . The satellite 300 helps determine the location of the mobile terminal 100 . Useful location information may be obtained by less than or equal to two or more satellites. Here, the location of the mobile terminal 100 can be tracked using not only the GPS tracking technology but also all technologies capable of tracking the location. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 provided in the mobile terminal is for detecting, calculating, or identifying the location of the mobile terminal, and representative examples may include a GPS (Global Position System) module and a WiFi (Wireless Fidelity) module. If necessary, the location information module 115 may perform any function among other modules of the wireless communication unit 110 to obtain data on the location of the mobile terminal in substitution or addition.

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 3-dimensional current location information according to latitude, longitude, and altitude. can do. Currently, a method of calculating location and time information using three satellites and correcting an error in the calculated location and time information using another satellite is widely used. In addition, the GPS module 115 may calculate speed information by continuously calculating the current location in real time. However, it is difficult to accurately measure the position of a mobile terminal using a GPS module in a shaded area of a satellite signal, such as indoors. Accordingly, in order to compensate for GPS positioning, a WiFi Positioning System (WPS) may be utilized.

The WiFi Positioning System (WPS) is a mobile terminal 100 using a WiFi module provided in the mobile terminal 100 and a wireless AP (Wireless Access Point) that transmits or receives a wireless signal with the WiFi module. As a technology for tracking the location of, it means a location positioning technology based on WLAN (Wireless Local Area Network) using WiFi.

The Wi-Fi location tracking system may include a Wi-Fi positioning server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database storing arbitrary wireless AP information.

The mobile terminal 100 accessing the wireless AP may transmit a location information request message to a Wi-Fi location determination server.

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

Based on the location information request message of the mobile terminal 100, the information of the wireless AP extracted is MAC Address, SSID (Service Set IDentification), RSSI (Received Signal Strength Indicator), RSRP (Reference Signal Received Power), RSRQ ( Reference Signal Received Quality), channel information, privacy, network type, signal strength (Signal Strength), and noise strength (Noise Strength).

As described above, the Wi-Fi positioning server may receive information on the wireless AP connected to the mobile terminal 100 and extract wireless AP information corresponding to the wireless AP the mobile terminal is accessing from a pre-built database. At this time, the information of arbitrary wireless APs stored in the database includes MAC address, SSID, channel information, privacy, network type, latitude and longitude coordinates of the wireless AP, building name where the wireless AP is located, number of floors, indoor detailed location information (GPS coordinates) available), AP owner's address, phone number, and the like. In this case, in order to remove mobile APs or wireless APs provided using illegal MAC addresses during the positioning process, the Wi-Fi positioning server may extract only a predetermined number of wireless AP information in order of highest RSSI.

Thereafter, the Wi-Fi positioning server may extract (or analyze) location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. The location information of the mobile terminal 100 is extracted (or analyzed) by comparing the included information with the received wireless AP information.

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

The Cell-ID method is a method of determining the location of a wireless AP having the strongest signal strength among information of surrounding wireless APs collected by a mobile terminal as the location of the mobile terminal. It has the advantages of simple implementation, no extra cost, and quick acquisition of location information. However, it has the disadvantage of low positioning accuracy when the installed density of wireless APs is low.

The fingerprint method is a method of selecting a reference location in a service area, collecting signal strength information, and estimating a location through signal strength information transmitted from a mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to make a database of propagation characteristics in advance.

The triangulation method is a method of calculating the position of a mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminal. In order to measure the distance between a mobile terminal and a wireless AP, signal strength is converted into distance information, or the time at which a wireless signal is transmitted (Time of Arrival, ToA) or the time difference between a signal is transmitted (Time Difference of Arrival, TDoA) , angle of arrival (AoA) at which the signal is transmitted, and the like can be used.

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

In addition to the listed methods, various algorithms may be used as a method for extracting (or analyzing) location information of a mobile terminal.

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

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

1, the mobile terminal according to the present invention includes Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), wireless USB (Wireless Universal Serial Bus), and other short-distance communication technologies may be applied.

Among them, the NFC module provided in the mobile terminal supports non-contact short-range wireless communication between terminals at a distance of around 10 cm. The NFC module may operate in one of card mode, reader mode, and P2P mode. In order for the NFC module to operate in a 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 universal integrated circuit card (UICC) (eg, a subscriber identification module (SIM) or a universal SIM (USIM)), a secure micro SD, and a sticker, or a logical medium embedded in a mobile terminal ( For example, it may be an embedded secure element (SE). Data exchange based on SWP (Single Wire Protocol) may be performed between the NFC module and the security module.

When the NFC module is operated in a card mode, the mobile terminal can transfer stored card information to the outside like a conventional IC card. Specifically, when a mobile terminal storing card information of a payment card, such as a credit card or bus card, is brought close to a fare payment machine, mobile short-distance payment can be processed, and the mobile terminal storing card information of an access card is authorized for access. When approaching the machine, access approval process may be started. Cards such as credit cards, transportation cards, and access cards are loaded in the security module in the form of an applet, and the security module can store card information about the loaded card. Here, the card information of the payment card may be at least one of a card number, balance, and usage history, and the card information of the access card may be at least one of the user's name, number (eg, the user's student number or employee number), and access history. can be one

When the NFC module operates in a reader mode, the mobile terminal can read data from an external tag. At this time, data received by the mobile terminal from the tag may be coded in an NFC Data Exchange Format (NFC Data Exchange Format) defined by the NFC forum. In addition, the NFC Forum defines 4 record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. When the data received from the tag is a smart poster type, the controller executes a browser (eg, an internet browser), and when the data received from the tag is a text type, the controller executes a text viewer. When the data received from the tag is a URI type, the control unit executes a browser or makes a phone call, and when the data received from the tag is a general control type, it can execute an appropriate operation according to the control content.

When the NFC module is operated in a peer-to-peer (P2P) mode, a mobile terminal can perform P2P communication with another mobile terminal. In this case, Logical Link Control Protocol (LLCP) may be applied to P2P communication. A connection may be created between a mobile terminal and another mobile terminal for P2P communication. At this time, the created 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 continuously exchanged. Through P2P communication, data such as electronic business cards, contact information, digital photos, URLs, and setup parameters for Bluetooth and Wi-Fi connections can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used for exchanging small-sized data.
