Description

[0001] MOBILE TERMINAL AND METHOD FOR CONTROLLING THE SAME [0002]

The present invention relates to a mobile terminal and a control method thereof. More particularly, the present invention relates to a mobile terminal to which a case having a polio cover is coupled, and a control method thereof.

A terminal can be divided into a mobile terminal (mobile / portable terminal) and a stationary terminal according to whether the terminal can be moved. The mobile terminal can be divided into a handheld terminal and a vehicle mounted terminal according to whether the user can directly carry the mobile terminal.

The functions of mobile terminals are diversified. For example, there are data and voice communication, photographing and video shooting through a camera, voice recording, music file playback through a speaker system, and outputting an image or video on a display unit. Some terminals are equipped with an electronic game play function or a multimedia player function. In particular, modern mobile terminals can receive multicast signals that provide visual content such as broadcast and video or television programs.

Such a terminal has various functions, for example, in the form of a multimedia device having multiple functions such as photographing and photographing of a moving picture, reproduction of a music or video file, reception of a game and broadcasting, etc. .

In recent years, a touch sensor has been added to a display unit to merely have an input function as well as an output function, thereby increasing the size of the display unit and minimizing other input means. In addition, in order to increase the size of the display unit, the thickness of the case protecting the periphery of the display unit is minimized, and the size and thickness of the case are reduced

Such a mobile terminal has a problem of being vulnerable to an external shock and uses a case to protect the mobile terminal. The case covers not only the bumper type that protects the side surface of the mobile terminal but also the rear cover type that covers the back surface of the mobile terminal but also the display portion on the front side when not in use, There is also a case of folio type.

On the other hand, in recent years, there have been many cases in which handwriting is performed on a mobile terminal using a stylus pen. However, if the mobile terminal does not have a structure capable of inserting the stylus pen, there is a disadvantage that it is highly likely to be lost because the user must carry the stylus pen directly.

Recently, the mobile terminal recognizes the operation of subtracting the stylus pen from the mobile terminal as a specific input, and automatically executes the memo application to provide convenience to the user. However, this convenience is disadvantageous in that it can be applied only to a mobile terminal capable of inserting a stylus pen therein.

Therefore, there is an urgent need to develop a mobile terminal and its control method solving the problems of the mobile terminal of the related art.

The present invention is directed to solving the above-mentioned problems and other problems. SUMMARY OF THE INVENTION It is an object of the present invention to provide a stylus pen detachable to a case coupled to a mobile terminal.

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 uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

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

In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system) can be applied.

Generally, 3D stereoscopic images consist of left image (left eye image) and right image (right eye image). A top-down method of arranging a left image and a right image in one frame according to a method in which a left image and a right image are combined into a three-dimensional stereoscopic image, A checker board system in which pieces of a left image and a right image are arranged in a tile form, a left-to-right (right-side) Or an interlaced method in which rows are alternately arranged, and a time sequential (frame-by-frame) method in which right and left images are alternately displayed in time.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (an image at a reference time point and an image at an expansion point), sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

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 mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output unit 152 also outputs sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The audio output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 153 may be vibration. The intensity and pattern of the vibration generated in the haptic module 153 can be controlled by the user's selection or the setting of the control unit. For example, the haptic module 153 may synthesize and output different vibrations or sequentially output the vibrations.

In addition to vibration, the haptic module 153 may be configured to perform various functions such as a pin arrangement vertically moving with respect to the contact skin surface, a spraying force or suction force of the air through the injection port or the suction port, a touch on the skin surface, And various tactile effects such as an effect of reproducing a cold sensation using an endothermic or exothermic element can be generated.

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

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the mobile terminal 100. The satellite 300 aids in locating the mobile terminal 100. Useful location information may be obtained by two or more satellites. Here, the position of the mobile terminal 100 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

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

The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.

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

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

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

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

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

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

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

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

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

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

As shown in FIG. 1A, a mobile terminal according to the present invention includes Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC Field Communication), and Wireless USB (Wireless Universal Serial Bus).

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (e.g., a SIM (Subscriber Identification Module) or a USIM (Universal SIM)), a Secure micro SD and a sticker, or a logical medium For example, embeded SE (Secure Element)). Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin. Cards such as credit cards, transportation cards, and access cards are mounted on the security module in the form of an applet, and the security module can store card information on the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage details, and the card information of the access card may include at least one of a name, a number (e.g., It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. At this time, the data received from the mobile terminal by the tag may be coded into a data exchange format (NFC Data Exchange Format) defined by the NFC Forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. If the data received from the tag is a smart poster type, the control unit executes a browser (e.g., an Internet browser), and if the data received from the tag is a text type, the control unit can execute the text viewer. When the data received from the tag is a URI type, the control unit executes the browser or makes a telephone call, and if the data received from the tag is a general control type, it can execute appropriate operations according to the control contents.

When the NFC module is operated in a peer-to-peer (P2P) mode, the mobile terminal can perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. For P2P communication, a connection can be created between the mobile terminal and another mobile terminal. At this time, the generated connection can be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are exchanged consecutively. Through P2P communications, data such as business cards, contact information, digital photos, URLs in electronic form, and setup parameters for Bluetooth and Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Preset  Condition Satisfied  Occation, Preset  How to display an application's run screen

According to an embodiment of the present invention, the controller 180 may control the display unit 151 to display an execution screen of a predetermined application when a preset condition is satisfied. This will be described with reference to Figs.

4 is a flowchart illustrating an example of displaying an execution screen of a predetermined application when a preset condition is satisfied in a mobile terminal according to an embodiment of the present invention. Hereinafter, it is assumed that the case having the polio cover is coupled to the mobile terminal.

According to an embodiment of the present invention, the stylus pen 300 may be removably attached to the case 200 by a magnetic force.

Specifically, magnets may be embedded in the case 200 and the stylus pen 300. The stylus pen may be engaged with the case by attraction of a magnet incorporated in the case and the stylus fan. Also, the stylus fan 300 may be separated from the case 200 by an external force.

Meanwhile, according to an embodiment of the present invention, the controller 180 may recognize whether a predetermined condition is satisfied (S410).

The predetermined condition may be satisfied when the polyo cover covers the front portion of the mobile terminal and the stylus pen is separated from the case.

A method of recognizing whether or not the predetermined condition is satisfied by the control unit 180 will be described below.

First, the control unit 180 can recognize whether the stylus pen 300 is separated from the case 200 through the hall sensor provided in the mobile terminal 100. Here, Hall sensor is a sensor that detects the direction and magnitude of a magnetic field by using a hall effect in which a voltage is generated in a direction perpendicular to a current and a magnetic field when a magnetic field is applied to a conductor through which current flows.

More specifically, when the stylus pen 300 is detached from the case 200, at least one of the magnitude of the magnetic field sensed by the hall sensor and the direction of the magnetic field is changed can do. In this case, the control unit 180 can recognize that the stylus pen 300 is separated from the case 200 through the hall sensor. However, the method of recognizing whether the stylus pen 300 is separated from the case 200 is not limited thereto, and the control unit 180 may be configured such that the stylus pen 300 is connected to the case 200 through various embodiments. It can be recognized whether or not it has been separated from the < / RTI >

According to an embodiment of the present invention, the control unit 180 may use at least one of the proximity sensor, the illuminance sensor, and the hall sensor so that the polyo cover of the case 200 covers the front portion of the mobile terminal 100 Or not.

A proximity sensor may be disposed on the front side of the mobile terminal 100. Accordingly, the proximity sensor can recognize whether or not the polyo cover 220 covers the front surface of the mobile terminal 100.

An illuminance sensor may be disposed on the front surface of the mobile terminal 100. Accordingly, when the ambient light sensor detects that the ambient light has been reduced to a predetermined level or less, the controller 180 can recognize that the polyo cover 220 covers the front portion of the mobile terminal 100. When the ambient light sensor detects that the ambient light exceeds a predetermined level, the controller 180 can recognize that the polyo cover 220 does not cover the front surface of the mobile terminal 100. [

A magnet may be disposed on the polio cover 220. When the polio cover 220 covers the front surface of the mobile terminal 100, at least one of the magnitude of the magnetic field sensed by the hall sensor and the direction of the magnetic field may be changed by a magnet disposed on the polio cover 220 have. The controller 180 may recognize that the polio cover 220 covers the front portion of the mobile terminal 100 when the change of the magnetic field is sensed through the hall sensor.

However, the present invention is not limited to the above-described embodiments. That is, the control unit 180 controls the front cover of the mobile terminal 100, It is possible to recognize whether or not it is covered.

If the predetermined condition is not satisfied (S410: No), the controller 180 may recognize whether the predetermined condition is satisfied at a predetermined time interval (for example, 5 seconds).

On the other hand, if the predetermined condition is satisfied (S410: Yes), the controller 180 may control the display unit S420 to display an execution screen of a predetermined application. Here, the predetermined application may be an application using the stylus pen 300. For example, the predetermined application may be an application that performs a memo function.

For example, when the predetermined condition is satisfied, the controller 180 may control the display unit 151 to display the execution screen of the predetermined application on the entire screen or a part of the screen.

Alternatively, when the predetermined condition is satisfied while the first execution screen of the specific application is being displayed, the control unit 180 displays the first execution screen on the first area and displays the execution screen of the preset application And to control the display unit 151 to display the second execution screen on the second area. However, in this case, the second area may be an area other than the first area, the size of the first execution screen may be changed according to the first area, 2 < / RTI > area. And, the first execution screen can be displayed in the first area, and the second execution screen can be displayed in the second area.

As another example, when the predetermined condition is satisfied while the first execution screen of the specific application is being displayed, the control unit 180 may control the display unit to display a pop-up window on a part of the first execution screen have. The control unit 180 may control the display unit 151 to display an execution screen of the predetermined application in the pop-up window.

Meanwhile, according to the embodiment, the controller 180 may control the display unit 151 to display the execution screen of the predetermined application when the preset condition and the additional condition are satisfied. Here, the additional condition may be satisfied when the case 200 is coupled to the mobile terminal 100 through the sensing unit 140 and the user recognizes that the mobile terminal 100 is held by his or her hand.

A method for recognizing whether or not the additional condition is satisfied is as follows.

The sensing unit 140 may sense information such as a motion and a tilt of the mobile terminal 100. Then, the controller 180 can recognize whether the user holds the mobile terminal 100 in his / her hand through the sensed information.

On the other hand, the case 200 may have a built-in magnet. The control unit 180 recognizes the change of the magnetic field through the hall sensor and recognizes whether the case 200 is coupled to the mobile terminal 100. [

According to the related art, there is no technology for automatically executing a memo application by interlocking the stylus pen 300, which is not inserted in the mobile terminal 100, with the mobile terminal 100. However, according to the above-described embodiment, there is an effect that the memo application can be automatically executed using the stylus pen 300 not inserted in the mobile terminal.
