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 present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive 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 explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected 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. Further, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor applies 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 portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

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 the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

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

On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, 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 object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position 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 user interface (UI) and graphical user interface (GUI) information according to the execution screen information. .

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and the right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail refers to a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated as described above are displayed with a left and right distance difference on the screen by a depth corresponding to the parallax of the left image and the right image, thereby representing a three-dimensional space.

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

The MSC is configured to connect with the Public Switched Telephone Network (PSTN) and BSCs. The BSCs may be connected to the 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 omnidirectional antenna or an antenna pointing in a radial direction from the BS. In addition, each sector may include two or more antennas of various types. Each BS may be configured to support a plurality of frequency assignments, and the plurality of frequency assignments may each have a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sectors and frequency assignments may be called a CDMA channel. BSs may be called Base Station Transceiver Subsystems (BTSs). In such a case, one BSC and at least one BS may be collectively called a conference. The base station may also indicate “cell site”. Or, each of the plurality of sectors for a particular BS may be called a plurality of cell sites.

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

In addition, a satellite positioning system (Global Positioning System, GPS) for identifying the position of the mobile terminal 100 may be linked to the CDMA wireless communication system. The satellite 300 helps to locate the mobile terminal 100. Useful location information may be obtained by up to two or more satellites. Here, the location of the mobile terminal 100 may be tracked using all the technologies capable of tracking the location as well as the GPS tracking technology. In addition, 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 used to detect, calculate, or identify the location of the mobile terminal. Examples of the location information module 115 may include a Global Position System (GPS) module and a Wireless Fidelity (WiFi) module. If necessary, the location information module 115 may perform any function of other modules of the wireless communication unit 110 to substitute or additionally obtain data regarding the location of the mobile terminal.

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

The Wi-Fi Positioning System (WPS) uses a WiFi module provided in the mobile terminal 100 and a wireless access point (AP) for transmitting or receiving a wireless signal with the WiFi module. As a technology for tracking the location of a, it refers to a WLAN (Wireless Local Area Network) based location positioning technology using WiFi.

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

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

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

Based on the location information request message of the mobile terminal 100, the extracted information of the wireless AP is MAC Address, Service Set IDentification (SSID), Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), RSRQ ( It may be at least one of Reference Signal Received Quality, Channel Information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi location server receives the information of the wireless AP connected to the mobile terminal 100, and extracts the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from a pre-established database. At this time, the information of any wireless AP stored in the database is MAC address, SSID, channel information, Privacy, Network Type, latitude and longitude coordinates of the wireless AP, building name, floor number, indoor detailed location information (GPS coordinates) Available), the AP owner's address, telephone number, and the like. In this case, in order to remove the wireless AP provided by the mobile AP or the illegal MAC address in the positioning process in the positioning process, the Wi-Fi positioning server may extract only a predetermined number of wireless AP information in the order of high RSSI.

Thereafter, the Wi-Fi location server may extract (or analyze) location information of the mobile terminal 100 using at least one piece of wireless AP information extracted from a 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) the location information of the mobile terminal 100, a cell-ID method, a finger print method, a triangulation method, a landmark method, or the like may be utilized.

The Cell-ID method is a method of determining the location of a mobile AP having the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. The simple implementation, no additional cost, and quick location information can be obtained. However, the low installation density of the wireless AP reduces the positioning accuracy.

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

The triangulation method calculates the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. In order to measure the distance between the mobile terminal and the wireless AP, the signal strength is converted into distance information, a time of arrival of a radio signal (ToA), a time difference of transmission of a signal (Time Difference of Arrival, TDoA) , Angle of signal transmission (Angle of Arrival, AoA) may 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 methods listed, various algorithms may be utilized 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, the mobile terminal 100 can obtain the location information.

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

As described above with reference to FIG. 1A, a mobile terminal according to the present invention includes Bluetooth ( ^TM ), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and NFC (Near). Short-range communication technologies such as field communication and wireless universal serial bus (USB) may be applied.

Among these, the NFC module provided in the mobile terminal supports contactless short-range wireless communication between terminals at a distance of about 10 cm. The NFC module may operate in any one of a card mode, a reader mode, and a 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) (for example, 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 SE (Secure Element). Data exchange based on a single wire protocol (SWP) may be performed between the NFC module and the security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside like a conventional IC card.

Specifically, when the mobile terminal storing the card information of the payment card such as a credit card or bus card is close to the toll payment machine, the mobile short-range payment can be processed, and the mobile terminal storing the card information of the access card is approved for access. Close to the flag, the approval process can be started. Cards such as credit cards, transportation cards, and access cards are mounted in a security module in the form of an applet, and the security module may store card information about the mounted 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 include at least one of a user's name, number (eg, student's student number or company number), and access history. It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. In this case, the data received by the mobile terminal from the tag may be coded in a data exchange format (NFC Data Exchange Format) determined by the NFC forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four record type definitions (RTDs) such as smart poster, text, uniform resource identifier (URI), and general control. If the data received from the tag is a smart poster type, the controller may execute a browser (eg, an Internet browser). If the data received from the tag is a text type, the controller may execute a text viewer. When the data received from the tag is a URI type, the controller executes a browser or makes a phone call, and when the data received from the tag is a general control type, the controller can execute an appropriate operation according to the control content.

When the NFC module is operated in a peer-to-peer mode, the mobile terminal may perform P2P communication with another mobile terminal. In this case, LLCP (Logical Link Control Protocol) may be applied to P2P communication. A connection may be created between the mobile terminal and another mobile terminal for P2P communication. In this case, the generated connection may be classified 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 available distance of NFC communication is short, the P2P mode may be effectively used for exchanging small data.
