On the other hand, 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 sensing signal corresponding thereto. The controller 180 may control the driving or operation of the mobile terminal 100 or perform data processing, function, or operation related to an 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 or absence of an object approaching a predetermined detection surface or an object existing in the vicinity without mechanical contact using the force of an electromagnetic field 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 type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, and an infrared proximity sensor. When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of an object having conductivity by a change in an 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, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. 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.) have. Meanwhile, the controller 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 printed on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor receives 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 a change in capacitance occurring in a specific part of the touch screen into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, an electrostatic capacitance at the time of touch, etc. in which a touch object applying a touch on 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, a signal(s) corresponding thereto is sent to the touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the controller 180 . Accordingly, the controller 180 can know which area of the display unit 151 has been touched, and the like. 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 may perform the same control according to the type of the 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 the touch object may be determined according to the current operating state of the mobile terminal 100 or a running application program.

On the other hand, the above-described touch sensor and proximity sensor independently or in combination, a short (or tap) touch on the touch screen (short touch), long touch (long touch), multi touch (multi touch), drag touch (drag touch) ), flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch, etc. It can sense touch.

The ultrasonic sensor may recognize position information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the position of the wave source through information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source may be calculated using the property that light is much faster than ultrasonic waves, that is, the time at which light arrives at the optical sensor is much faster than the time at which ultrasonic waves reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference from the time that the ultrasonic wave arrives using light as a reference signal.

On the other hand, the camera 121 as seen in 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 target for a 3D stereoscopic image. The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the motion of the sensing target close to the touch screen. More specifically, the photo sensor mounts photo diodes and transistors (TRs) in rows/columns and scans the contents placed on the photo sensors 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 target according to the amount of change in light, and through this, location information of the sensing target 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 the execution screen information. .

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

A three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glassesless method), or a projection method (holographic method) may be applied to the stereoscopic display unit.

In general, a 3D stereoscopic image consists of a left image (image for left eye) and a right image (image for right eye). Depending on the method in which the left and right images are merged into a 3D stereoscopic image, a top-down method in which the left and right images are placed up and down in one frame, and the left and right images in one frame L-to-R (left-to-right, side by side) method, which arranges the pieces of the left and right images in tiles Alternatively, it is divided into an interlaced method in which rows are alternately arranged, and a time sequential (frame by frame) method in which a left image and a right image are displayed alternately by time.

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

The left image and the right image necessary for realizing the 3D stereoscopic image may be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (a reference view image and an extended view image) and sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

The sound 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.

In addition, electronic paper is a display technology to which the characteristics of general ink are applied, and may differ from the conventional flat panel display in that it uses reflected light. Electronic paper can change information by using a twisted ball or by using electrophoresis using a capsule.

In a state in which the flexible display unit 251 is not deformed (eg, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display unit 251 becomes a flat surface. In a state deformed by an external force from the first state (eg, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As shown, the information displayed in the second state may be visual information output on the curved surface. Such visual information is implemented by independently controlling the emission of sub-pixels arranged in a matrix form. The unit pixel means a minimum unit for realizing one color.

Here, the information related to the deformation may be a direction in which the flexible display unit 251 is deformed, a deformed degree, a deformed position, a deformed time, and an acceleration at which the deformed flexible display unit 251 is restored. In addition, it may be various pieces of information detectable due to the bending of the flexible display unit 251 .

It is possible to generate a control signal to control the function of

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 accommodating the flexible display unit 251 . The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251 .

In addition, a battery (not shown) included in the mobile terminal 200 may also be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251 . In order to implement the battery, a stack and folding method in which battery cells are stacked upward may be applied.

In this drawing, although the camera 421 is exemplified that the control module 480 is provided, the present invention is not limited thereto. The camera 421 may be installed in the frame unit, or a plurality of cameras 421 may be provided to obtain a stereoscopic image.

The glass-type mobile terminal 400 may include user input units 423a and 423b operated to receive a control command. The user input units 423a and 423b may be adopted in any manner as long as they are operated in a tactile manner, such as by touch or push, while the user feels a tactile feeling. In this figure, it is exemplified that the frame unit and the control module 480 are provided with user input units 423a and 423b of push and touch input methods, respectively.

In addition, the glass-type mobile terminal 400 may include a microphone (not shown) that receives sound and processes it into electrical voice data and a sound output module 452 that outputs sound. The sound output module 452 may be configured to transmit sound in a general sound output method or bone conduction method. When the sound output module 452 is implemented in a bone conduction method, when the user wears the mobile terminal 400, the sound output module 452 is in close contact with the head and vibrates the skull to deliver sound.

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

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

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

The CDMA wireless communication system includes at least one terminal 100, at least one base station (Base Station, BS (also referred to as Node B or Evolved Node B)), and at least one base station controller (Base Station Controllers, BSCs). ), and a mobile switching center (MSC). The MSC is configured to be connected to a 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, and xDSL. Accordingly, a plurality of BSCs may 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 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 multiple frequency assignments, and each of the multiple frequency assignments may have a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency allocation may be referred to as a CDMA channel. BSs may be referred to as Base Station Transceiver Subsystems (BTSs). In this case, the one BSC and the at least one BS may be collectively referred to as a hoe 誰仄. A base station may also refer to 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 broadcast transmitter (BT) transmits a broadcast signal to the terminals 100 operating in the system. The broadcast reception module 111 shown in FIG. 1A is provided in the terminal 100 to receive a broadcast signal transmitted by BT.

In addition, a global positioning system (GPS) for confirming the location of the mobile terminal 100 may be linked to the CDMA wireless communication system. The satellite 300 helps to determine the location of the mobile terminal 100 . Useful location information may be obtained by two or fewer or more satellites. Here, the location of the mobile terminal 100 may be tracked using not only the GPS tracking technology but also all techniques capable of tracking the location. 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 for detecting, calculating, or identifying the location of the mobile terminal, and representative examples thereof 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 the other modules of the wireless communication unit 110 to obtain data on the location of the mobile terminal as a substitute or additionally.

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

A WiFi positioning system (WPS) uses 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, the mobile terminal 100 As a technology for tracking the location of a wireless network, it refers to a wireless local area network (WLAN)-based positioning technology using WiFi.

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

The Wi-Fi positioning server extracts information on the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100 . Information on 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 wireless AP information is MAC Address, Service Set IDentification (SSID), Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), RSRQ ( Reference Signal Received Quality), channel information, Privacy, Network Type, signal strength, and noise strength may be at least one.

As described above, the Wi-Fi positioning server may receive information of a wireless AP connected to the mobile terminal 100 and extract wireless AP information corresponding to a wireless AP to which the mobile terminal is connected from a pre-established 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, the name of the building where the wireless AP is located, the number of floors, and detailed indoor location information (GPS coordinates). available), the AP owner's address, phone number, and the like. In this case, in order to remove a mobile AP or a wireless AP provided using an illegal MAC address in the positioning process, the Wi-Fi positioning server may extract only a predetermined number of wireless AP information in order of increasing RSSI.

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

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

The Cell-ID method is a method of determining the location of a wireless AP having the strongest signal strength among surrounding wireless AP information collected by the mobile terminal as the location of the mobile terminal. It has the advantages of being simple to implement, not requiring additional cost, and being able to quickly obtain location information, but has a disadvantage in that the positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method is a method of collecting signal strength information by selecting a reference position in a service area, and estimating the position 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 the mobile terminal and the wireless AP, the signal strength is converted into distance information, the time at which a wireless signal is transmitted (Time of Arrival, ToA), and the time difference of the signal is transmitted (Time Difference of Arrival, TDoA) , the angle at which the signal is transmitted (Angle of Arrival, AoA), etc. 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 enumerated methods, 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, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may acquire location information by being connected to at least one wireless AP. In this case, 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.

1A, in the mobile terminal according to the present invention, Bluetooth ^TM , RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near) Field Communication), a short-distance communication technology such as Wireless USB (Wireless Universal Serial Bus) may be applied.

Among them, 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 the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a 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 the 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 card mode, the mobile terminal may transmit stored card information to the outside like a traditional IC card.

Specifically, when a mobile terminal that stores card information of a payment card, such as a credit card or a bus card, is brought close to a payment machine, a mobile short-distance payment can be processed, and the mobile terminal that stores card information of the access card is approved for access Approaching the flag, the access approval process can begin. 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 may 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 is at least one of a user's name, number (eg, user's student number or company number), and access details. can be one

When the NFC module is operated in the reader mode, the mobile terminal may read data from an external tag. In this case, data received by the mobile terminal from the tag may be coded in a 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. 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 controller executes a browser or makes a call, and when the data received from the tag is a general control type, an appropriate operation may be executed according to the control content.

When the NFC module operates in a peer-to-peer (P2P) mode, the mobile terminal may perform P2P communication with another mobile terminal. In this case, a Logical Link Control Protocol (LLCP) may be applied to P2P communication. For P2P communication, a connection may be created between a mobile terminal and another mobile terminal. In this case, the generated connection may 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 the like and setup parameters for Bluetooth and Wi-Fi connection may be exchanged. However, since the available distance of NFC communication is short, the P2P mode may be effectively utilized for exchanging small-sized data.

Furthermore, when the specific Aquino 2611 is clicked three times, the cursor is designed to be displayed again instead of the aforementioned figures.

27 to 31 are diagrams for explaining a third additional function provided by a mobile device according to an embodiment of the present invention. The third additional function provides a function of adding an underline to the file being presented. In particular, regardless of the vertical position change of the mobile device, only position information according to the horizontal position change is transmitted to the display device, so that the position of the underline is not changed even if the user moves the mobile device vertically by mistake.

As shown in FIG. 27 , it is possible to move the position of the cursor from the first point 2710 to the second point 2720 through the motion of the mobile device. However, there is a need for a user to highlight a corresponding area by displaying an underline connecting the corresponding points. To implement this, as shown in FIG. 28, when the auto shape button is touched for a preset time (ex: 1 second), other parts are disabled while sub-icon lists 2811, 2812, 2813 is displayed. In this case, two embodiments may be considered as a method of selecting a sub icon for an underline. First, as shown in FIG. 29, the sub icon 2910 for the underline may be selected by dragging 2920 from the initial point, or as shown in FIG. 30, simply touching the same sub icon 3010 without dragging. It is also possible

Accordingly, as shown in FIG. 31 , the underline starts from the last point 3110 where the cursor was displayed, and the underline 3121 ends when the touch on the specific sub icon 2910 or 3010 ends ( 3120 ). ). Of course, as another embodiment, it is also possible to design the underline to be continuously drawn according to the degree of movement of the mobile device. There are technical effects that can increase

32 is a diagram for explaining a fourth additional function provided by a mobile device according to an embodiment of the present invention. The fourth additional function relates to a method of notifying another function while using the mobile device as a pointing device.

When a text message is received from another mobile phone while using the mobile device as a pointing device, as shown in FIG. 32 , the screen 3220 for the pointing device is maintained and only a simple notification 3210 for message reception is displayed. It has the advantage of being able to quickly check whether a text message has been received while minimizing the interruption to the text message. In the prior art, there was a problem in that an existing function was stopped and a pop-up alarm was generated.
