Title: Mobile terminal and control method therefor

Description:
TECHNICAL FIELD 
     The present invention relates to a mobile terminal capable of outputting prescribed information in response to a touch input received when the mobile terminal is in an idle state and a method of controlling therefor. 
     BACKGROUND ART 
     Generally, terminals can be classified into mobile/portable terminals and stationary terminals according to a presence or non-presence of mobility. And, the mobile terminals can be further classified into handheld terminals and vehicle mounted terminals according to availability for hand-carry. 
     Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs. 
     As the functions of the terminals are diversified, for example, the terminals are implemented in a form of a multimedia player equipped with complex functions such as capturing pictures or videos, playing music and video files, gaming, receiving broadcasting, and the like. 
     As functions of mobile terminals are diversified, various data can be handled by the mobile terminals. As a result, the importance of security of the mobile terminals is also increasing. As an example, in order to protect the privacy of a mobile terminal, it may set a password to the mobile terminal. The mobile terminal to which the password is set can make a user not to access data until the lock of the mobile terminal is cancelled via the password. 
     However, in this case, when the user intends to check simple information via the mobile terminal, if the mobile terminal asks the user to cancel the password, it may cause inconvenience of the user. Hence, the present invention proposes a mobile terminal capable of checking brief information provided by the mobile terminal by inputting a simple touch input to the mobile terminal in an idle state.

     [[UX Part Start]] 
     Referring still to  FIG. 1A , various components depicted in this figure will now be described in more detail. Regarding the wireless communication unit  110 , the broadcast receiving module  111  is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules  111  may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels. 
     The mobile communication module  112  can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like). Examples of wireless signals transmitted and/or received via the mobile communication module  112  include audio call signals, video (telephony) call signals, or various formats of data to support communication of text and multimedia messages. 
     The wireless Internet module  113  is configured to facilitate wireless Internet access. This module may be internally or externally coupled to the mobile terminal  100 . The wireless Internet module  113  may transmit and/or receive wireless signals via communication networks according to wireless Internet technologies. 
     Examples of such wireless Internet access include Wireless LAN (WLAN), Wireless Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), Worldwide Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like. The wireless Internet module  113  may transmit/receive data according to one or more of such wireless Internet technologies, and other Internet technologies as well. 
     In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module  113  performs such wireless Internet access. As such, the Internet module  113  may cooperate with, or function as, the mobile communication module  112 . 
     The short-range communication module  114  is configured to facilitate short-range communications. Suitable technologies for implementing such short-range communications include BLUETOOTH™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless USB (Wireless Universal Serial Bus), and the like. The short-range communication module  114  in general supports wireless communications between the mobile terminal  100  and a wireless communication system, communications between the mobile terminal  100  and another mobile terminal  100 , or communications between the mobile terminal and a network where another mobile terminal  100  (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks. 
     In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal  100 ) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the mobile terminal  100  (or otherwise cooperate with the mobile terminal  100 ). The short-range communication module  114  may sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal  100 . In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal  100 , the controller  180 , for example, may cause transmission of data processed in the mobile terminal  100  to the wearable device via the short-range communication module  114 . Hence, a user of the wearable device may use the data processed in the mobile terminal  100  on the wearable device. For example, when a call is received in the mobile terminal  100 , the user may answer the call using the wearable device. Also, when a message is received in the mobile terminal  100 , the user can check the received message using the wearable device. 
     The location information module  115  is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module  115  includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module  115  may alternatively or additionally function with any of the other modules of the wireless communication unit  110  to obtain data related to the position of the mobile terminal. 
     As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module. 
     The input unit  120  may be configured to permit various types of input to the mobile terminal  120 . Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras  121 . Such cameras  121  may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit  151  or stored in memory  170 . In some cases, the cameras  121  may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal  100 . As another example, the cameras  121  may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image. 
     The microphone  122  is generally implemented to permit audio input to the mobile terminal  100 . The audio input can be processed in various manners according to a function being executed in the mobile terminal  100 . If desired, the microphone  122  may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio. 
     The user input unit  123  is a component that permits input by a user. Such user input may enable the controller  180  to control operation of the mobile terminal  100 . The user input unit  123  may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the mobile terminal  100 , a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof. 
     The sensing unit  140  is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller  180  generally cooperates with the sending unit  140  to control operation of the mobile terminal  100  or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit  140 . The sensing unit  140  may be implemented using any of a variety of sensors, some of which will now be described in more detail. 
     The proximity sensor  141  may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor  141  may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen. 
     The proximity sensor  141 , for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor  141  can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor. 
     The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor  141  may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like). 
     In general, controller  180  processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor  141 , and cause output of visual information on the touch screen. In addition, the controller  180  can control the mobile terminal  100  to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch. 
     A touch sensor can sense a touch applied to the touch screen, such as display unit  151 , using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others. 
     As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit  151 , or convert capacitance occurring at a specific part of the display unit  151 , into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like. 
     When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller  180 . Accordingly, the controller  180  may sense which region of the display unit  151  has been touched. Here, the touch controller may be a component separate from the controller  180 , the controller  180 , and combinations thereof. 
     In some embodiments, the controller  180  may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal  100  or a currently executed application program, for example. 
     The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like. 
     If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller  180 , for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal. 
     The camera  121  typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor. 
     Implementing the camera  121  with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object. 
     The display unit  151  is generally configured to output information processed in the mobile terminal  100 . For example, the display unit  151  may display execution screen information of an application program executing at the mobile terminal  100  or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information. 
     In some embodiments, the display unit  151  may be implemented as a stereoscopic display unit for displaying stereoscopic images. A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like. 
     [[3D Start]] 
     In general, a 3D stereoscopic image may include a left image (e.g., a left eye image) and a right image (e.g., a right eye image). According to how left and right images are combined into a 3D stereoscopic image, a 3D stereoscopic imaging method can be divided into a top-down method in which left and right images are located up and down in a frame, an L-to-R (left-to-right or side by side) method in which left and right images are located left and right in a frame, a checker board method in which fragments of left and right images are located in a tile form, an interlaced method in which left and right images are alternately located by columns or rows, and a time sequential (or frame by frame) method in which left and right images are alternately displayed on a time basis. 
     Also, as for a 3D thumbnail image, a left image thumbnail and a right image thumbnail can be generated from a left image and a right image of an original image frame, respectively, and then combined to generate a single 3D thumbnail image. In general, the term “thumbnail” may be used to refer to a reduced image or a reduced still image. A generated left image thumbnail and right image thumbnail may be displayed with a horizontal distance difference there between by a depth corresponding to the disparity between the left image and the right image on the screen, thereby providing a stereoscopic space sense. 
     A left image and a right image required for implementing a 3D stereoscopic image may be displayed on the stereoscopic display unit using a stereoscopic processing unit. The stereoscopic processing unit can receive the 3D image and extract the left image and the right image, or can receive the 2D image and change it into a left image and a right image. 
     [[3D End]] 
     The audio output module  152  is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit  110  or may have been stored in the memory  170 . The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module  152  can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal  100 . The audio output module  152  may also be implemented as a receiver, a speaker, a buzzer, or the like. 
     A haptic module  153  can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module  153  is vibration. The strength, pattern and the like of the vibration generated by the haptic module  153  can be controlled by user selection or setting by the controller. For example, the haptic module  153  may output different vibrations in a combining manner or a sequential manner. 
     Besides vibration, the haptic module  153  can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like. 
     The haptic module  153  can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user&#39;s fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules  153  may be provided according to the particular configuration of the mobile terminal  100 . 
     An optical output module  154  can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal  100  may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. 
     A signal output by the optical output module  154  may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example. 
     The interface unit  160  serves as an interface for external devices to be connected with the mobile terminal  100 . For example, the interface unit  160  can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal  100 , or transmit internal data of the mobile terminal  100  to such external device. The interface unit  160  may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like. 
     The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal  100  and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal  100  via the interface unit  160 . 
     When the mobile terminal  100  is connected with an external cradle, the interface unit  160  can serve as a passage to allow power from the cradle to be supplied to the mobile terminal  100  or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle. 
     The memory  170  can store programs to support operations of the controller  180  and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory  170  may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen. 
     The memory  170  may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The mobile terminal  100  may also be operated in relation to a network storage device that performs the storage function of the memory  170  over a network, such as the Internet. 
     The controller  180  may typically control the general operations of the mobile terminal  100 . For example, the controller  180  may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition. 
     The controller  180  can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller  180  can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein. 
     The power supply unit  190  receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal  100 . The power supply unit  190  may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging. 
     The power supply unit  190  may include a connection port. The connection port may be configured as one example of the interface unit  160  to which an external charger for supplying power to recharge the battery is electrically connected. 
     As another example, the power supply unit  190  may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit  190  can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance. 
     Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof. 
     Referring now to  FIGS. 1B and 1C , the mobile terminal  100  is described with reference to a bar-type terminal body. However, the mobile terminal  100  may alternatively be implemented in any of a variety of different configurations. Examples of such configurations include watch-type, clip-type, glasses-type, or as a folder-type, flip-type, slide-type, swing-type, and swivel-type in which two and more bodies are combined with each other in a relatively movable manner, and combinations thereof. Discussion herein will often relate to a particular type of mobile terminal (for example, bar-type, watch-type, glasses-type, and the like). However, such teachings with regard to a particular type of mobile terminal will generally apply to other types of mobile terminals as well. 
     The mobile terminal  100  will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case  101  and a rear case  102 . Various electronic components are incorporated into a space formed between the front case  101  and the rear case  102 . At least one middle case may be additionally positioned between the front case  101  and the rear case  102 . 
     The display unit  151  is shown located on the front side of the terminal body to output information. As illustrated, a window  151   a  of the display unit  151  may be mounted to the front case  101  to form the front surface of the terminal body together with the front case  101 . 
     In some embodiments, electronic components may also be mounted to the rear case  102 . Examples of such electronic components include a detachable battery  191 , an identification module, a memory card, and the like. Rear cover  103  is shown covering the electronic components, and this cover may be detachably coupled to the rear case  102 . Therefore, when the rear cover  103  is detached from the rear case  102 , the electronic components mounted to the rear case  102  are externally exposed. 
     As illustrated, when the rear cover  103  is coupled to the rear case  102 , a side surface of the rear case  102  is partially exposed. In some cases, upon the coupling, the rear case  102  may also be completely shielded by the rear cover  103 . In some embodiments, the rear cover  103  may include an opening for externally exposing a camera  121   b  or an audio output module  152   b.    
     The cases  101 ,  102 ,  103  may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like. 
     As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal  100  may be configured such that one case forms the inner space. In this example, a mobile terminal  100  having a uni-body is formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface. 
     If desired, the mobile terminal  100  may include a waterproofing unit (not shown) for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window  151   a  and the front case  101 , between the front case  101  and the rear case  102 , or between the rear case  102  and the rear cover  103 , to hermetically seal an inner space when those cases are coupled. 
       FIGS. 1B and 1C  depict certain components as arranged on the mobile terminal. However, it is to be understood that alternative arrangements are possible and within the teachings of the instant disclosure. Some components may be omitted or rearranged. For example, the first manipulation unit  123   a  may be located on another surface of the terminal body, and the second audio output module  152   b  may be located on the side surface of the terminal body. 
     The display unit  151  outputs information processed in the mobile terminal  100 . The display unit  151  may be implemented using one or more suitable display devices. Examples of such suitable display devices include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, an e-ink display, and combinations thereof. 
     The display unit  151  may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units  151  may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces. 
     The display unit  151  may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit  151 , the touch sensor may be configured to sense this touch and the controller  180 , for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes. 
     The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window  151   a  and a display on a rear surface of the window  151   a , or a metal wire which is patterned directly on the rear surface of the window  151   a . Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display. 
     The display unit  151  may also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit  123  (see  FIG. 1A ). Therefore, the touch screen may replace at least some of the functions of the first manipulation unit  123   a.    
     The first audio output module  152   a  may be implemented in the form of a speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like. 
     The window  151   a  of the display unit  151  will typically include an aperture to permit audio generated by the first audio output module  152   a  to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window  151   a  and the front case  101 ). In this case, a hole independently formed to output audio sounds may not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal  100 . 
     The optical output module  154  can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit  154  to stop the light output. 
     The first camera  121   a  can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit  151  or stored in the memory  170 . 
     The first and second manipulation units  123   a  and  123   b  are examples of the user input unit  123 , which may be manipulated by a user to provide input to the mobile terminal  100 . The first and second manipulation units  123   a  and  123   b  may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units  123   a  and  123   b  may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like. 
       FIG. 1B  illustrates the first manipulation unit  123   a  as a touch key, but possible alternatives include a mechanical key, a push key, a touch key, and combinations thereof. 
     Input received at the first and second manipulation units  123   a  and  123   b  may be used in various ways. For example, the first manipulation unit  123   a  may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit  123   b  may be used by the user to provide an input to control a volume level being output from the first or second audio output modules  152   a  or  152   b , to switch to a touch recognition mode of the display unit  151 , or the like. 
     As another example of the user input unit  123 , a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal  100 . The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules  152   a  or  152   b , switch to a touch recognition mode of the display unit  151 , and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof. 
     The rear input unit may be located to overlap the display unit  151  of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body. 
     Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit  123   a  in the rear input unit. As such, in situations where the first manipulation unit  123   a  is omitted from the front side, the display unit  151  can have a larger screen. 
     As a further alternative, the mobile terminal  100  may include a finger scan sensor which scans a user&#39;s fingerprint. The controller  180  can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit  151  or implemented in the user input unit  123 . 
     The microphone  122  is shown located at an end of the mobile terminal  100 , but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds. 
     The interface unit  160  may serve as a path allowing the mobile terminal  100  to interface with external devices. For example, the interface unit  160  may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal  100 . The interface unit  160  may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage. 
     The second camera  121   b  is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit  121   a . If desired, second camera  121   a  may alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown. 
     The second camera  121   b  can include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera  121   b  is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities. 
     As shown in  FIG. 1C , a flash  124  is shown adjacent to the second camera  121   b . When an image of a subject is captured with the camera  121   b , the flash  124  may illuminate the subject. 
     As shown in  FIG. 1B , the second audio output module  152   b  can be located on the terminal body. The second audio output module  152   b  may implement stereophonic sound functions in conjunction with the first audio output module  152   a , and may be also used for implementing a speaker phone mode for call communication. 
     At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module  111  may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover  103 , or a case that includes a conductive material. 
     A power supply unit  190  for supplying power to the mobile terminal  100  may include a battery  191 , which is mounted in the terminal body or detachably coupled to an outside of the terminal body. The battery  191  may receive power via a power source cable connected to the interface unit  160 . Also, the battery  191  can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance. 
     The rear cover  103  is shown coupled to the rear case  102  for shielding the battery  191 , to prevent separation of the battery  191 , and to protect the battery  191  from an external impact or from foreign material. When the battery  191  is detachable from the terminal body, the rear case  103  may be detachably coupled to the rear case  102 . 
     An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal  100  can also be provided on the mobile terminal  100 . As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal  100  may be provided. The cover or pouch may cooperate with the display unit  151  to extend the function of the mobile terminal  100 . Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen. 
     For clarity, assume that the mobile terminal according to the present invention includes at least one of the configuration elements shown in  FIGS. 1 a  to 1 c   . For example, it may assume that the mobile terminal according to the present invention includes a camera  121 , a sensing unit  140 , a display unit  151 , a memory  170 , and a controller  180  among the configuration elements shown in  FIGS. 1 a    to  1   c.    
     In the following, assume that the display unit  151  corresponds to a touch screen. If the display unit  151  corresponds to a touch screen, the display unit  151  can function not only as an input device for receiving a touch input but also as an output device for outputting information. 
     If the display unit  151  corresponds to a touch screen, a touch input of various types can be received via the display unit  151 . For example, a touch input touching the display unit  151  one time, a long touch input touching the display unit  151  for more than prescribed time, a touch input tapping the display unit  151  more than a prescribed count, a drag or flicking input for moving a pointer touching the display unit  151  in a prescribed direction, and the like can be received via the display unit  151 . 
     A touch input rubbing the display unit  151  can be received via the display unit  151  (hereinafter, the touch input rubbing the display unit  151  is referred to as a rubbing touch). If a pointer touching the display unit  151  is sensed and a movement of the pointer satisfies a prescribed condition, the controller  180  can recognize it as a rubbing touch is inputted. 
     For example,  FIG. 2  is a diagram for explaining an input condition of a rubbing touch. In  FIGS. 2 ( a ) and ( b ) , an oval indicates a position at which a pointer is touched and a dotted line and an arrow indicate a moving path of a pointer touching the display unit  151 . 
     If the display unit  151  corresponds to a touch screen, a touch pad can be attached to the other side of the display unit  151 . A plurality of sensing points  210  (or, touch sensors) may exist on the touch pad and the controller  180  can recognize a touch position of a pointer based on a sensing signal sensed at each sensing point. 
     As shown in  FIG. 2 ( a ) , if a maximum moving distance (d1) of a pointer rubbing the display unit  151  is equal to or greater than a first reference value (r1) (i.e., a maximum distance between a plurality of sensing points at which a touch of the pointer is sensed), or as shown in  FIG. 2 ( b ) , if the count (N1) of moving back and forth of a pointer is equal to or greater than a predetermined count (R1), the controller  180  can determine it as a rubbing touch is received. Or, if a movement of a pointer satisfying the conditions shown in  FIGS. 2 ( a ) and ( b )  is sensed, the controller  180  can determine it as a rubbing touch is received. 
     In the example shown in  FIG. 2 ( a ) , if the maximum moving distance of the pointer is too long (e.g., if the moving distance of the pointer is equal to or greater than a second reference value), the controller may determine it as a rubbing touch is not inputted. 
       FIG. 3  is a diagram for explaining an input condition of a rubbing touch. When a first region  310  and second region  320  surrounding the first region (yet, the second region  320  does not include the first region  310 ) are set on a touch pad, if a pointer moves back and forth on the second region  320  to repeatedly touch and release the second region while consistently touching the first region  310 , the controller  180  can determine it as a rubbing touch is inputted. For example, as shown in  FIGS. 3 ( a ) to ( c ) , if an action of touching the first region  310  and the second region  320  at the same time-&gt;touching the first region  310 -&gt;touching the first region  310  and the second region  320  at the same time is repeated more than a prescribed count in a manner that the pointer is dragged, the controller  180  can determine it as a rubbing touch is inputted. 
       FIGS. 3 ( a ) to ( c )  show a case that a plurality of sensing points exist on the first region  310  and the second region  320 . Unlikely, a single sensing point may exist on the first region  310  and the second region  320 . 
     When the first region  310  and the second region  320  are configured, the controller  180  may consider a moving trajectory of a pointer touching the display unit  151 . For example, if the pointer is dragged to a second point from a first point on the display unit  151 , the first region  310  can be configured between the first point and the second point and the second region  320  can be configured at the outside of the first point and the second point. 
       FIG. 4  is a diagram for explaining an input condition of a rubbing touch. The controller  180  can configure a first region  410 , a second region  420 , and a third region  430  surrounding the second region  420 . If a touch of a pointer touching the first region  410  is maintained, a touch and release on the second region  420  is repeated more than a prescribed count, and the third region  430  is not touched, the controller  180  can determine it as a rubbing touch is inputted. 
     As an example, as shown in  FIGS. 4 ( a ) to ( c ) , if a pointer touches the third region  430  in the middle of moving back and forth on the second region  420  on the basis of the first region  410  (refer to  FIG. 4 ( c ) ), the controller  180  can determine it as a rubbing touch is not inputted. 
     As a different example, although the third region  430  is touched, if the third region  430  is touched as many as a count equal to or less than a prescribed count, or if a touch count of the third region  430  is less than a touch count of the second region  420 , the controller  180  can determine it as a rubbing touch is inputted. 
     Although a mobile terminal is in an idle state, the controller  180  can receive a touch input touching the display unit  151 . In this case, the idle state may correspond to a state that the mobile terminal is not used. In order to reduce unnecessary power consumption, the display unit  151  can maintain an off state (or inactivate state) in the idle state of the mobile terminal. In this case, the off state of the display unit  151  corresponds to a state that a light for lighting the display unit  151  is turned off. Information or a graphic image is not outputted on the display unit  151  in the off state of the display unit  151 . Although the display unit  151  is in the off state, a touch panel maintains an active state to sense a touch input touched on the display unit  151 . Yet, when the mobile terminal is in the idle state, a period of activating a sensing point on a touch pad may be longer than a period when the mobile terminal is not in the idle state. 
     On the contrary, a state that the display unit  151  is turned on (or, activated state) corresponds to a state that a light for lighting the display unit  151  is turned on. In the state that the display unit  151  is turned on, information or a graphic image can be outputted according to a control of the controller  180 . 
     If the idle state of the mobile terminal ends, the display unit  151  may enter a semi active state. The semi active state may correspond to a state that a part of the display unit  151  is turned off and the rest of the display unit is turned on. In this case, information or a graphic image is not outputted on a part where the display unit  151  is turned off. Yet, information or a graphic image can be outputted on a part where the display unit  151  is turned on. 
     For clarity, a state that the mobile terminal is deviated from the idle state is referred to as a normal state. In the normal state, the display unit  151  can maintain a state that the entire display unit is activated or a state that a part of the display unit is activated. 
     As mentioned in the foregoing description, a mobile terminal according to the present invention can receive a touch input of various types in an idle state. The present invention intends to propose various methods of operating the mobile terminal via a rubbing touch when the mobile terminal is in the idle state. In the following, each of embodiments is explained as a separate category. Yet, it is apparent that each of the embodiments can be applied to a single mobile terminal. 
     In the following, the mobile terminal according to the present invention is explained in detail. 
     &lt;Information Display&gt; 
       FIG. 5  is a flowchart for a method of operating a mobile terminal according to the present invention. Assume that the mobile terminal is initially laid in an idle state. 
     Referring to  FIG. 5 , if a rubbing touch is received via the display unit  151  [S 501 ], the controller  180  switches the mobile terminal into a normal state and controls prescribed information to be outputted via a position at which the rubbing touch is received [S 502 ]. In this case, the information outputted via the display unit  151  can include weather information, time information, date information, or event information (In this case, an event can include message reception, e-mail reception, occurrence of an unanswered call, and the like.). 
     For example,  FIG. 6  is a diagram for an example of outputting prescribed information via a display unit. As shown in the example of  FIG. 6 ( a ) , if a touch input rubbing the display unit  151  is received, as shown in  FIG. 6 ( b ) , the controller  180  can control prescribed information to be outputted.  FIG. 6 ( b )  shows an example that weather information  610  is outputted in response to a rubbing touch. 
     The controller  180  can control the prescribed information to be outputted at a position at which the rubbing touch is received. Moreover, the controller  180  can configure at least one of a horizontal length and a vertical length of the prescribed information in accordance with a moving length of a pointer, which have inputted the rubbing touch horizontally or vertically. 
     For example, as shown in  FIG. 6 ( a ) , if a maximum moving length of a pointer, which has moved vertically to input a rubbing touch, corresponds to d1, the controller  180  can control a vertical length of the displayed information  610  to be configured by d1 as well. 
     The controller  180  can control prescribed information to be outputted while turning on the whole of the display unit  151 . Or, the controller  180  can control a region on which the prescribed information  610  is to be outputted to be turned on only among the entire region of the display unit  151 . In this case, the controller  180  can control the remaining region to maintain an off state. 
     The controller  180  can control the prescribed information  610  to be outputted only when the pointer, which has inputted the rubbing touch, touches the display unit  151 . Specifically, if the pointer, which has inputted the rubbing touch, touches the display unit  151 , as shown in the example of  FIG. 6 ( b ) , the controller  180  controls the prescribed information to be outputted. If the pointer, which has inputted the rubbing touch, is released from the display unit  151 , as shown in the example of  FIG. 6 ( c ) , the controller can control the prescribed information not to be outputted. In this case, the controller  180  turns off the display unit  151  and can control the mobile terminal to enter an idle state. 
     When the prescribed information is outputted, if the pointer is dragged to the outside of a region on which the prescribed information is outputted, the controller  180  can control other information to be outputted. 
     For example,  FIG. 7  is a diagram for an example of changing outputted information. 
     If a rubbing touch is inputted, the controller  180  can control first information  710  to be outputted in response to the rubbing touch.  FIG. 7 ( a )  shows an example that weather information is outputted in response to the rubbing touch. In this case, if a pointer moves to the outside of a region on which the first information  710  is outputted, the controller  180  stops outputting the first information  710  and can control second information  720  to be outputted. 
     For example, if the pointer moves to the outside of the region on which the weather information  710  is outputted, as shown in the example of  FIG. 7 ( b ) , the controller  180  stops outputting the weather information  710  and can control time information  720  to be outputted. 
     In this case, a position at which the second information  720  is outputted can be determined based on a position to which the pointer is dragged. For example, referring to  FIG. 7 , as the pointer is dragged to the right side of the weather information  710 , the time information  720  is outputted at the right side of the weather information  710 . 
     &lt;Playing Multimedia File&gt; 
       FIG. 8  is a flowchart for a method of operating a mobile terminal according to the present invention. Assume that the mobile terminal is initially laid in an idle state. 
     Referring to  FIG. 8 , if a rubbing touch is received via the display unit  151  [S 801 ], the controller  180  can control a play button for playing a multimedia file to be outputted near a position to which the rubbing touch is inputted [S 802 ]. In this case, the multimedia file can include a music file or a video file. The music file or the video file may correspond to a file stored in the memory  170  or a server. 
     If a pointer is dragged onto the play button [S 803 ], the controller  180  can play the multimedia file [S 804 ]. An example of playing the multimedia file is explained in detail with reference to  FIG. 9  in the following. 
       FIG. 9  is a diagram for an example of playing a multimedia file. 
     If a rubbing touch is received, as shown in the example of  FIG. 9 ( a ) , the controller  180  can control a play button  910  for playing a multimedia file to be outputted at a position to which the rubbing touch is inputted or a position near the position to which the rubbing touch is inputted.  FIG. 9 ( a )  shows an example of outputting the play button  910  at the position near the position to which the rubbing touch is inputted. 
     Subsequently, as shown in the example of  FIG. 9 ( b ) , if the pointer touching the display unit  151  is dragged onto the play button  910 , the controller  180  can control the multimedia file to be played. In this case, the multimedia file may correspond to a most recently listened multimedia file by a user or a multimedia file selected by the user in advance. 
     If the pointer deviates from the play button [S 805 ], the controller  180  can stop playing the multimedia file [S 806 ]. 
     In this case, although the pointer has deviated from the play button, if the pointer is still touching the display unit  151 , the controller  180  can control the mobile terminal to maintain a normal state. On the contrary, if the touch of the pointer, which has deviated from the play button, is released from the display unit  151 , the controller  180  can control the mobile terminal to reenter an idle state. 
     In particular, the controller  180  can control the mobile terminal to maintain the normal state only when the pointer touches the display unit  151 . 
     For example, as shown in the example of  FIG. 9 ( c ) , although the pointer has deviated from the play button  910 , if the pointer is still touching the display unit  151 , the controller  180  can stop playing the multimedia file, whereas the display unit  151  can continuously maintain the on state. 
     Although a touch of the pointer is released from the display unit  151 , the controller  180  can control the multimedia file to be continuously played according to a configuration of a user. 
     For example,  FIG. 10  is a diagram for a different example of playing a multimedia file. 
     If a play button  1010  is touched, the controller  180  can start to play the multimedia file. If the playback of the multimedia file starts, as shown in the example of  FIG. 10 ( a ) , the controller  180  can control a full screen button  1020  for watching the multimedia file in full screen and a continuous play button  1030  for continuously playing the multimedia file although the play button  1010  is not touched to be outputted. 
     Referring to the example shown in  FIG. 10 ( a ) , if the full screen button  1020  is touched, as shown in the example of  FIG. 10 ( b ) , the controller  180  can control the multimedia file to be played in full screen. If the full screen button  1020  is retouched while the multimedia file is played in full screen, as shown in the example of  FIG. 10 ( a ) , the controller  180  can control the multimedia file to be outputted via a partial region of the display unit  151  again. 
     If the pointer touching the play button  1010  is dragged onto the full screen button  1020  or a different pointer touches the full screen while the play button  1010  is touched by the pointer, the controller  180  can control the multimedia file to be played in full screen. 
     Referring to the example shown in  FIG. 10 ( a ) , if the continuous play button  1030  is touched, as shown in  FIG. 10 ( c ) , although the touch of the pointer is released from the display unit  151 , the controller  180  can control the multimedia file to be continuously played. 
     In this case, the touch input touching the play button  1010  can be inputted by dragging the pointer touching the play button  1010  to the continuous play button  1030  or touching the continuous play button  1030  by a different pointer while the play button  1010  is touched. 
     If the continuous play button  1030  is touched, although the pointer does not touch the display unit  151 , the controller  180  can control the multimedia file to be continuously played. In this case, the controller  180  outputs a stop button  1040  for stopping the playback of the multimedia file. If the sop button  1040  is touched, the controller can stop playing the multimedia file. 
     For example,  FIG. 11  is a diagram for explaining an example of stopping the playback of a multimedia file. 
     If a continuous play button  1110  is touched, although a pointer does not touch the display unit  151 , the controller  180  can play a multimedia file. If the continuous play button  1110  is touched, as shown in the example of  FIG. 11 ( a ) , the controller  180  can output a stop button  1120  for terminating the playback of the multimedia file via the display unit  151 . 
     If the stop button  1120  is touched, the controller  180  can stop playing the multimedia file. When the playback of the multimedia file is stopped, as shown in the example of  FIG. 11 ( b ) , the controller  180  can control the mobile terminal to enter an idle state. 
     In particular, if the touch of the pointer is released from the display unit  151  before the continuous play button  1110  is selected, the mobile terminal enters the idle state. Yet, if the stop button  1120  is selected after the continuous play button  1110  is selected, the mobile terminal can enter the idle state. 
     &lt;Checking Message&gt; 
       FIG. 12  is a flowchart for a method of operating a mobile terminal according to the present invention. Assume that the mobile terminal is initially laid in an idle state. And, assume that a new event has occurred in the mobile terminal. In this case, the event can include message reception, e-mail reception, occurrence of an unanswered call, and the like. 
     Referring to  FIG. 12 , if a rubbing touch is received via the display unit  151  [S 1201 ], the controller  180  can control an icon for checking an event to be outputted [S 1202 ]. In this case, the icon may correspond to an icon of an application capable of checking detail contents of an event. For example, if a text message is received in the mobile terminal, the icon outputted by the rubbing touch may correspond to an icon of a text message application. An example of outputting an icon is explained with reference to  FIG. 13  in the following. 
       FIG. 13  is a diagram for an example of outputting an icon for checking an event. As shown in  FIG. 13 ( a ) , if a touch input rubbing the display unit  151  is received, as shown in the example of  FIG. 13 ( b ) , the controller  180  can control an icon for checking an event to be displayed.  FIG. 13 ( b )  shows the example that a text message icon  1310  for checking a text message, an instant message icon  1320  for checking an instant message, and an unanswered call icon  1330  for checking an unanswered call are outputted. 
     If a pointer touching the display unit  151  is dragged onto a displayed icon [S 1203 ], the controller  180  can control detail content of an event to be outputted [S 1204 ]. 
     For example,  FIG. 14  is a diagram for an example of outputting detail content of an event. 
     If a pointer touching the display unit  151  is dragged onto the text message icon  1410 , as shown in the example of  FIG. 14 ( a ) , the controller  180  can control a pop-up window  1415  including detail content of a received text message to be outputted via the display unit  151 . 
     If the pointer is dragged to the instant message icon  1420  from the text message icon, as shown in the example of  FIG. 14 ( b ) , the controller  180  can control a pop-up window  1425  including detail content of a received instant message to be outputted via the display unit  151 . 
     If the pointer is dragged to the unanswered call icon  1430  from the instant message icon, as shown in the example of  FIG. 14 ( c ) , the controller  180  can control a pop-up window  1435  including detail content of an unanswered call to be outputted via the display unit  151 . 
     In the examples shown in  FIGS. 13 and 14 , the controller  180  can control a region on which an application icon or detail information of an event is outputted to maintain on state and control the remaining region to maintain off state. 
     In addition, in the examples shown in  FIGS. 13 and 14 , if a touch of the pointer is released from the display unit  151 , the controller  180  can stop outputting an icon or detail information. While the output of the icon or the detail information is stopped, the controller  180  can configure the mobile terminal to enter an idle state. In particular, the controller  180  can control the mobile terminal to maintain the normal state only when the pointer touches the display unit  151 . 
     Unlikely, if the pointer is dragged to detail content of an event from a specific icon or the touch of the pointer is released from the display unit  151  after the pointer is dragged to the detail content of the event [S 1205 ], the controller  180  can execute an application corresponding to the selected event [S 1206 ]. 
     For example,  FIG. 15  is a diagram for an example of executing an application in response to a selected event. 
     As shown in the example of  FIG. 15 ( a ) , if a pointer touching a text message icon  1510  is dragged to a pop-up window  1520  including detail content of a text message, the controller  180  can execute a text message application. In this case, as shown in the example of  FIG. 15 ( b ) , the controller  180  can control message content transceived with a counterpart (i.e., a counterpart who has sent the message) to be outputted while executing the text message application. 
     Although it is not depicted, if the pointer is dragged to a pop-up window including detail content of an instant message from an instant message icon, the controller  180  can execute an instant message application. In this case, the controller  180  can control a conversation window with a counterpart (i.e., a counterpart who has sent the instant message) to be outputted while executing the instant message application. 
     Although it is not depicted, if the pointer is dragged to a pop-up window including detail content of an unanswered call from an unanswered call icon, the controller  180  can execute a call application. In this case, the controller  180  can control a telephone number of a counterpart (i.e., a counterpart who has made the unanswered call) to be inputted to a dial screen of the call application. By doing so, a user can easily make a call to the person who has made the unanswered call. 
     &lt;Flash On/Off&gt; 
       FIG. 16  is a flowchart for a method of operating a mobile terminal according to the present invention. Assume that the mobile terminal is initially laid in an idle state. 
     Referring to  FIG. 16 , if a rubbing touch is received via the display unit  151  [S 1601 ], the controller  180  can control a flash button for turning on a flash to be outputted [S 1602 ]. If the pointer is dragged to the flash button, the controller  180  can turn on the flash [S 1604 ]. 
     If the pointer deviates from the flash button [S 1605 ], the controller  180  can turn off the flash [S 1606 ]. 
     In this case, although the pointer has deviated from the flash button, if the pointer is still touching the display unit  151 , the controller  180  can control the flash button to be continuously outputted via the display unit  151 . Unlikely, if the touch of the pointer, which have deviated from the flash button, is released from the display unit  151 , the controller  180  can configure the mobile terminal to enter an idle state while turning off the display unit  151 . 
       FIG. 17  is a diagram for an example of turning on/off a flash. 
     If a rubbing touch input is received via the display unit  151 , as shown in the example of  FIG. 17 ( a ) , the controller  180  can control a flash button  1710  to be outputted. If a pointer touching the display unit  151  is dragged to the flash button  1710 , as shown in the example of  FIG. 17 ( b ) , the controller  180  can control the flash to be turned on. 
     In the example shown in  FIG. 17 , the controller  180  can control a region on which the flash button  1710  is to be outputted to maintain on state and control the remaining region to maintain off state. 
     Subsequently, if the pointer deviates from the flash button  1710 , the controller  180  can turn off the flash. In this case, if the touch of the pointer is released from the display unit  151 , as shown in the example of  FIG. 17 ( c ) , the controller  180  can control the mobile terminal to enter an idle state while turning off the flash. 
     &lt;Capturing Picture&gt; 
       FIG. 18  is a flowchart for a method of operating a mobile terminal according to the present invention. Assume that the mobile terminal is initially laid in an idle state. 
     Referring to  FIG. 18 , if a rubbing touch is received via the display unit  151  [S 1801 ], the controller  180  can control a camera button for activating a camera  121  to be outputted [S 1802 ]. If a pointer is moved to the camera button  121  [S 1803 ], the controller  180  activates the camera  121  and can control a preview image to be outputted via the display unit  151  [S 1804 ]. 
     In this case, the preview image may correspond to an image inputted in real time via the camera  121  before a picture or a video is captured. 
     If the preview image is outputted, the controller  180  can control a shutter button (or capturing button) to be additionally outputted [S 1804 ]. If a pointer is dragged onto the shutter button [S 1805 ], the controller  180  can control the camera  121  to capture a picture [S 1806 ]. 
     For example,  FIG. 19  is a diagram for an example of capturing a picture. 
     If a rubbing touch is received, as shown in an example of  FIG. 19 ( a ) , the controller  180  can control a camera button  1910  for activating a camera  121  to be outputted. In this case, the controller  180  can control a region on which the camera button  1910  is outputted to maintain on state and control the remaining region to maintain off state among the entire region of the display unit  151 . 
     If the pointer is dragged onto the camera button  1910 , the controller  180  activates the camera  121 , and as shown in the example of  FIG. 19 ( b ) , the controller can control a preview image  1920 , which is inputted in real time via the camera  121 , to be outputted. 
     In this case, the controller  180  can control a shutter button  1930  to be outputted together with the preview image  1920 . If the pointer is dragged onto the shutter button  1930 , the controller  180  can control the camera  121  to capture a picture. In this case, the controller  180  can capture a picture after performing auto focusing on a specific subject. 
     If a picture is captured, as shown in the example of  FIG. 19 ( c ) , the controller  180  can control the captured picture to be outputted via the display unit  151  [S 1807 ]. 
     In the example shown in  FIG. 19 , if a touch of the pointer is released from the display unit  151 , the controller  180  deactivate the camera  121  and can control the mobile terminal to enter an idle state. In particular, the controller  180  can control the mobile terminal to maintain the normal state only when the pointer touches the display unit  151 . 
     If prescribed time elapses after the captured picture is outputted [S 1810 ], the controller  180  stops outputting the captured picture and can control the preview image to be outputted again [S 1811 ]. 
     Meanwhile, if a touch input for dragging the pointer onto a picture, which is outputted via the display unit  151 , is received before prescribed time elapses [S 1808 ], the controller  180  can control the captured picture to be continuously outputted [S 1809 ]. In this case, although the touch of the pointer is released from the display unit  151 , the controller  180  can control the picture to be continuously outputted via the display unit  151 . 
       FIG. 20  is a diagram for an example of outputting a preview image or a captured picture. 
     If a picture is captured, as mentioned earlier with reference to  FIG. 19  ( c ), the controller  180  can control the captured picture to be outputted via the display unit  151 . 
     In this case, when prescribed time elapsed after the picture is captured, if an additional touch input of a predetermined type (e.g., a touch input for dragging a pointer onto the captured picture  2010 ) is not received, as shown in the example of  FIG. 20 ( a ) , the controller  180  stops outputting the captured picture  2010  and can control a preview image  2020  to be outputted. 
     Meanwhile, if an additional touch input of a predetermined type (e.g., a touch input for dragging a pointer onto the captured picture  2010 ) is received before prescribed time elapses, as shown in an example of  FIG. 20 ( b ) , the controller  180  can control the captured picture  2010  to be continuously outputted although the prescribed time elapses. 
     Unlike the example shown in  FIG. 20 , when a picture is captured, the controller  180  can control the captured picture to be outputted while a touch touching a shutter button is maintained. If the touch touching the shutter button is released, the controller  180  can controller  180  can control a preview image to be outputted. 
     For example,  FIG. 21  is a diagram for an example of outputting a preview image or a captured picture. 
     As shown in the example of  FIGS. 21 ( a ) and ( b ) , if a pointer is moved to a shutter button, the controller  180  captures a picture  2120  in response to the movement of the pointer and can control the captured picture  2120  to be outputted. 
     In this case, if a touch touched on the shutter button is maintained, the controller  180  can control the captured picture  2120  to be continuously outputted while the touch touched on the shutter button is maintained. 
     Meanwhile, if the pointer deviates from the shutter button, as shown in the example of  FIG. 21 ( c ) , the controller  180  stops outputting the captured picture  2120  and can control a preview image  2110  to be outputted. If a user drags the pointer onto the shutter button while the preview image  2110  is outputted, it may be able to capture a picture  2120  again. 
     &lt;Outputting List of Recently Executed Applications&gt; 
       FIG. 22  is a flowchart for a method of operating a mobile terminal according to the present invention. Assume that the mobile terminal is initially laid in an idle state. 
     Referring to  FIG. 22 , if a rubbing touch is received via the display unit  151  [S 2201 ], the controller  180  can control a list of recently executed applications to be outputted [S 2202 ]. 
     For example,  FIG. 23  is a diagram for an example of outputting a list of applications. 
     As shown in the example of  FIG. 23 ( a ) , if a touch input rubbing the display unit  151  is received, as shown in the example of  FIG. 23 ( b ) , the controller  180  can control a list of recently executed applications  2310  to be outputted.  FIG. 23 ( b )  shows an example that a text message application, an instant message application, a call application, a camera  121  application, a video application, and a map application are included in the list of recently executed applications. The controller  180  can control a region on which the application list is outputted to maintain on state and control the remaining region to maintain off state among the entire region of the display unit  151 . 
     In this case, the controller  180  may consider a case that a rubbing touch is received when the mobile terminal is laid horizontally (i.e., landscape mode) and a case that a rubbing touch is received when the mobile terminal is laid vertically (i.e., portrait mode). In the former case, the controller  180  outputs a list of applications operated in the landscape mode among the recently executed applications. In the latter case, the controller  180  outputs a list of applications operated in the portrait mode among the recently executed applications. In this case, the controller  180  can determine whether the mobile terminal is laid in horizontally or vertically based on a signal sensed by the sensing unit  140 . 
     For example,  FIG. 24  is a diagram for an example of outputting a list of recently executed applications in a portrait mode and a landscape mode. 
     If a touch input rubbing the display unit  151  is received in a state that the mobile terminal is laid vertically (i.e., portrait mode), among the recently executed applications, the controller  180  can control a list  2410  of applications executed in the portrait mode to be outputted.  FIG. 24 ( a )  shows an example that a text message application, an instant message application, and a call application are outputted as the list of recently executed applications. 
     If a touch input rubbing the display unit  151  is received in a state that the mobile terminal is laid horizontally (i.e., landscape mode), among the recently executed applications, the controller  180  can control a list  2420  of applications executed in the landscape mode to be outputted.  FIG. 24 ( b )  shows an example that a camera  121  application, a video application, and a map application are outputted as the list of recently executed applications. 
     If a pointer is dragged onto an item among the list of applications [S 2203 ], the controller  180  can control a preview of an application corresponding to the selected item to be outputted [S 2204 ]. In this case, the preview may correspond to a screen which is expected to be outputted when the application corresponding to the selected item is executed. The preview may correspond to a screen outputted at the time of terminating an application. 
     For example,  FIG. 25  is a diagram for an example of outputting a preview. 
     If a pointer touching the display unit  151  is dragged onto an application item among a list of applications, the controller  180  can output a preview of an application corresponding to the selected application item. For example, as shown in the example of  FIG. 25 ( a ) , if the pointer is dragged onto a video application, as shown in the example of  FIG. 25 ( b ) , the controller  180  can control a preview  2510  of the video application to be outputted. 
     In this case, the preview of the video application may correspond to a screen which is outputted at the time of terminating the execution of the video application. 
     In the examples shown in  FIGS. 23 to 25 , if a touch of the pointer is released from the display unit, the controller  180  stops outputting a list of applications or a preview of an application and can configure the mobile terminal to be in an idle state. In particular, the controller  180  can control the mobile terminal to maintain the normal state only when the pointer touches the display unit  151 . 
     Meanwhile, if the pointer is dragged to the preview or a touch of the pointer, which is dragged to the preview, is released from the display unit  151  [S 2205 ], the controller  180  can control a corresponding application to be executed [S 2206 ]. 
     For example,  FIG. 26  is a diagram for an example of executing an application. 
     If an item is selected from a list of applications, as mentioned earlier in  FIG. 26 ( a ) , a preview of the selected item can be outputted.  FIG. 26 ( a )  shows an example that a preview  2610  of a video application is outputted. 
     In this case, if a pointer is dragged into the preview of the video application from the item indicating the video application, the controller  180  can control the video application to be executed.  FIG. 26 ( b )  shows an example that a playback screen for playing a multimedia file, which is played at the time of terminating the video application, is outputted according to the execution of the video application. 
     &lt;Outputting Quick Setting Menu&gt; 
       FIG. 27  is a flowchart for a method of operating a mobile terminal according to the present invention. Assume that the mobile terminal is initially laid in an idle state. 
     Referring to  FIG. 27 , if a rubbing touch is received via the display unit  151  [S 2701 ], the controller  180  switches the mobile terminal into a normal state and can control a setting menu for controlling a setting of the mobile terminal via the display unit  151  to be outputted [S 2702 ]. The setting menu can include a button for turning on/off various communication modules (e.g., Wi-Fi, Bluetooth, NFC, etc.) mounted on the mobile terminal, a button for turning on/off airplane mode, a button for turning on/off a power saving mode, a button for controlling a vibration mode or a sound mode, and the like. 
     If a pointer is dragged onto a button of the setting menu or prescribed time elapses after the pointer is dragged onto a button [S 2703 ], the controller  180  can control a setting value corresponding to the selected button [S 2704 ]. 
     For example,  FIG. 28  is a diagram for an example of outputting a setting menu. 
     If a touch input rubbing the display unit  151  is received, as shown in the example of  FIG. 28 ( a ) , the controller  180  can control a setting menu  2810  for controlling a setting value of the mobile terminal to be outputted.  FIG. 28 ( a )  shows an example that the setting menu  2810  includes a button  2811  for controlling on/off of a Bluetooth module, a button  2813  for controlling on/off of a Wi-Fi module, a button  2815  for controlling on/off of a power saving mode, a button  2817  for controlling on/off of an airplane mode, and a button  2819  for controlling on/off of an NFC module. In this case, among the entire region of the display unit  151 , the controller  180  can control a region on which the setting menu  2810  is outputted to maintain on state and control the remaining region to maintain off state. 
     If prescribed time elapses after the pointer is dragged onto a button, the controller  180  can control a setting value corresponding to the selected button to be changed. 
     For example, as shown in the example of  FIG. 28 ( b ) , if the pointer is dragged onto the button  2811  for controlling on/off of the Bluetooth module and a touch touched on the button for controlling on/off of the Bluetooth module is maintained for more than prescribed time, as shown in the example of  FIG. 28 ( c ) , the controller  180  can control a setting value for the Bluetooth module to be changed.  FIGS. 28 ( b ) and ( c )  show an example that the Bluetooth module is changed to on state from off state. 
     In the example shown in  FIG. 28 , if a touch of the pointer is released from the display unit  151 , the controller  180  can configure the mobile terminal to be in an idle state. In particular, the controller  180  can control the mobile terminal to maintain the normal state only when the pointer touches the display unit  151 . 
     &lt;Outputting Handler for Displaying Graphic Object&gt; 
     Referring to  FIGS. 5, 8, 12, 16, 18, 22, and 27 , if a rubbing touch is received, a prescribed graphic object is outputted via the display unit  151  in response to the rubbing touch. As mentioned earlier with reference to the drawings, the graphic object can include prescribed information (e.g., weather information or date information), an application icon for checking an event, a prescribed button (e.g., a camera button, a flash button, etc.), a list of applications, a setting menu, and the like. 
     Unlike the example, if a rubbing touch is received, the controller  180  may output a handler for outputting a graphic object. If a user input for selecting the handler is received, the controller  180  can control the graphic object to be outputted. 
     For example,  FIG. 29  is a diagram for an example of outputting a handler. 
     If a touch input rubbing the display unit  151  is received, as shown in an example of  FIG. 29 ( a ) , the controller  180  can control a handler  1910  for outputting a graphic object to be outputted. In this case, the handler may correspond to a predetermined image object or a part of a graphic object to be outputted in the future. 
     Subsequently, if a pointer is dragged towards the handler  2910  or the pointer is dragged onto the handler  2910 , as shown in an example of  FIG. 29 ( b ) , the controller  180  can control a graphic object to be outputted. 
       FIG. 29 ( b )  shows the example that weather and time information  2920  are outputted according to the pointer which is dragged to a position near the handler  2910 . 
     Unlike the example shown in  FIG. 29 ( b ) , if the pointer is dragged to the position near the handler, an application icon for checking an event, a flash button, a camera button, a list of applications, a setting menu, and the like can be outputted. 
     If a touch of the pointer is released from the display unit  151 , as shown in an example of  FIG. 29 ( c ) , the controller  180  can configure the mobile terminal to be in an idle state. 
     &lt;Controlling Setting Value&gt; 
     As mentioned earlier in the introduction part, the mobile terminal according to the present invention can receive a touch input touching the display unit  151  in an idle state. Hence, if a touch input of a predetermined type is received via the display unit  151 , the controller  180  can control the mobile terminal to switch to a normal state from the idle state. 
     For example, if a touch input tapping the display unit  151  two times is received or a touch pattern tapping the display unit  151  is matched with a predetermined password, the controller can control the mobile terminal to deviate from the idle state. 
     In this case, if a touch input rubbing the display unit  151  is received, the controller  180  can control a button for determining whether or not the idle state of the mobile terminal is terminated by a touch input tapping the display unit  151  to be outputted. 
     If it is determined as the idle state of the mobile terminal is not terminated by the touch input tapping the display unit  151 , although the touch input tapping the display unit  151  is received, the controller  180  can control the mobile terminal to maintain the idle state. 
     For example,  FIG. 30  is a diagram for an example of outputting a button for controlling a setting value of a mobile terminal. 
     If a touch input rubbing the display unit  151  is received, as shown in an example of  FIG. 30 ( a ) , the controller  180  can control a setting button  3010  capable of determining whether or not the idle state of the mobile terminal is terminated by tapping the display unit  151  to be outputted. 
     Subsequently, if a pointer is dragged to the setting button  3010  or the pointer, which is dragged to the setting button  3010 , touches the setting button  3010  for more than prescribed time, the controller  180  can control a setting value to be changed. 
     For example,  FIGS. 30 ( a ) and ( b )  shows an example that a setting value is changed to ‘disable’ (i.e., non-permit) from ‘enable’ (i.e., permit). 
     If the setting value corresponds to ‘enable’, the controller  180  can control the idle state of the mobile terminal to be terminated in response to a tapping input of a predetermined type tapping the display unit  151  (e.g., a touch input tapping the display unit  151  two times or a tapping input of a pattern matched with a predetermined password). 
     On the contrary, if the setting value corresponds to ‘disable’, although a tapping input of a predetermined type tapping the display unit  151  is received, the controller  180  can control the mobile terminal to maintain the idle state. 
     &lt;Commonly Applied Item&gt; 
     According to the aforementioned embodiments, if a touch of a pointer is released from the display unit after the rubbing touch is inputted, the mobile terminal reenters an idle state. Meanwhile, although the touch of the pointer is released from the display unit, the controller  180  can control a graphic object to be continuously outputted for prescribed time. If the pointer retouches the display unit  151  within the prescribed time, the controller can control the graphic object to be continuously outputted. If a touch input touching the display unit  151  is not received within the prescribed time, the controller can control the mobile terminal to enter the idle state. 
     Moreover, according to the aforementioned embodiments, a rubbing touch is inputted when the mobile terminal is in the idle state. Yet, although a rubbing touch is inputted when the mobile terminal is in a normal state, it may be able to perform the same operation. 
     In case of using a rubbing touch, a user can conveniently operate the mobile terminal by a hand holding the mobile terminal. In this case, the controller  180  can control a graphic object to be outputted via the display unit only when a touch input rubbing the display unit  151  using a finger of a hand holding the mobile terminal is received. For example, when a user holds the mobile terminal by a right hand, if a touch input rubbing the mobile terminal using a finger (e.g., a thumb of a right hand) of the right hand is received, the controller can control a graphic object to be outputted. Yet, if a touch input rubbing the mobile terminal using a finger (e.g., a thumb of a left hand) of the left hand is received, the controller can omit the output of the graphic object. 
     In this case, the controller  180  can check a position of a hand holding the mobile terminal bases on a signal sensed by the sensing unit  140  (e.g., grip sensor) and can also determine whether or not a rubbing touch is inputted by a finger of the hand holding the display unit  151  based on a moving trajectory of a pointer rubbing the display unit  151 . 
     For example,  FIG. 31  is a diagram for explaining an example of determining a position of a finger according to a moving trajectory of a pointer. Assume that a thumb rubs the display unit  151 . In this case, as shown in an example of  FIG. 31  ( a ), if a moving trajectory of a pointer is inclined in a clockwise direction, the controller  180  can determine it as a rubbing touch is inputted by a finger of a right hand. On the contrary, as shown in an example of  FIG. 31 ( b ) , if a moving trajectory of a pointer is inclined in an anticlockwise direction, the controller  180  can determine it as a rubbing touch is inputted by a finger of a left hand. 
     According to the aforementioned embodiments, it is explained as a graphic object is outputted via the display unit  151  in response to a rubbing touch. Yet, a graphic object can also be outputted in response to a touch input of a form different from the rubbing touch. For example, a graphic object can be outputted on the display unit  151  based on a touch input tapping the display unit  151  for more than a prescribed count, a drag input following a prescribed trajectory, and the like. 
     A graphic object can be outputted on the display unit  151  not only by a touch input but also by a gesture input using a mobile terminal or a push input pushing a button. 
     According to the aforementioned embodiments, such a graphic object as a button is outputted via the display unit  151 . Although the button has a closed outline such as a circle or a box in general, it is not mandatory. For example, as shown in the example of  FIG. 23 , each of items constructing a list can be regarded as a button as well. Moreover, a text not having a closed outline can be used as a button as well. In particular, a button described in the present invention may correspond to a common name of an object selected (touched) by a user to perform a specific action. In particular, the aforementioned icon can also be regarded as a sort of a button capable of being used by a user. 
     According to a part of the aforementioned embodiments, for clarity, it is explained as such a graphic object as an icon is outputted via the display unit  151 . Yet, the icon can be replaced with a graphic object (e.g., text) of a different form capable of being selected by a user. 
     As mentioned earlier in the introduction part, the aforementioned embodiments can be applied to a single mobile terminal. For example, the controller  180  can divide the display unit  151  into a plurality of virtual regions and may be then able to control a graphic object to be outputted according to a region on which a rubbing touch is received. 
     For example, if a rubbing touch is inputted on a first region of the display unit  151 , as mentioned earlier with reference to  FIG. 5 , the controller can control prescribed information to be outputted. If a rubbing touch is inputted on a second region of the display unit  151 , as mentioned earlier with reference to  FIG. 8 , the controller can control a play button for playing a multimedia file to be outputted. 
     As a different example, the controller  180  can control a plurality of graphic objects to be outputted at the same time in response to a rubbing touch. 
     For example, if a rubbing touch is inputted, the controller  180  can output the prescribed information mentioned earlier in  FIG. 5  and the play button mentioned earlier in  FIG. 8  at the same time. 
     According to one embodiment of the present invention, the aforementioned method (operation flowchart) can be implemented with a code readable by a processor in a program (or application) or a recording media in which the program is recorded. The examples of the recording media readable by the processor may include a ROM, a RAM, a magnetic tape, a floppy disc, an optical data storing device and the like. And, implementing in a form of a carrier wave such as a transmission via the internet and the like is also included. 
     The aforementioned mobile terminal  100  is not restricted by the configuration and the method of the aforementioned embodiments. In order to make various variations from the embodiments, all or a part of the embodiments can be selectively combined.
