[0077] Hereinafter, prior to examining various embodiments implemented through the mobile terminal 100, the above-listed components are described in more detail with reference to FIG. 1.

[0078] First, in describing the wireless communication unit 110, the broadcast receiving module 111 of the wireless communication unit 110 may receive a broadcast signal and/or broadcast related information from an external broadcast management server through a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. At least two broadcast receiving modules for simultaneous broadcast reception for at least two broadcast channels or broadcast channel switching may be provided to the mobile terminal 100.

[0079] The mobile communication module 112 may transmit/receive a wireless signal to/from at least one of a base station, an external terminal, and a server on a mobile communication network established according to the technical standards or communication methods for mobile communication (for example, Global System for Mobile communication (GSM), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), and Long Term Evolution-Advanced (LTE-A)).

[0080] The wireless signal may include various types of data according to a voice call signal, a video call signal, or text/multimedia message transmission.

[0081] The wireless Internet module 113 refers to a module for wireless Internet access and may be built in or external to the mobile terminal 100. The wireless Internet module 113 may be configured to transmit/receive a wireless signal in a communication network according to wireless Internet technologies.

[0082] The wireless Internet technology may include Wireless LAN (WLAN), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), World Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), and Long Term Evolution-Advanced (LTE-A) and the wireless Internet module 113 transmits/receives data according at least one wireless Internet technology including Internet technology not listed above.

[0083] From the viewpoint that wireless Internet access by WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, and LTE-A is achieved through a mobile communication network, the wireless Internet module 113 performing wireless Internet access through the mobile communication network may be understood as one type of the mobile communication module 112.

[0084] The short-range communication module 114 may support short-range communication by using at least one of Bluetooth™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, and Wireless Universal Serial Bus (USB) technologies. The short-range communication module 114 may support wireless communication between the mobile terminal 100 and a wireless communication system, between the mobile terminal 100 and another mobile terminal 100, or between networks including the mobile terminal 100 and another mobile terminal 100 (or an external server) through wireless area networks. The wireless area networks may be wireless personal area networks.

[0085] Here, the other mobile terminal 100 may be a wearable device (for example, a smart watch, a smart glass, and an HMD) that is capable of exchanging data (or interworking) with the mobile terminal 100. The short-range communication module 114 may detect (or recognize) a wearable device around the mobile terminal 100, which is capable of communicating with the mobile terminal 100 Furthermore, if the detected wearable device is a device authenticated to communicate with the mobile terminal 100, the control unit 180 may transmit at least part of data processed in the mobile terminal 100 to the wearable device through the short-range communication module 114. Accordingly, a user of the wearable device may use the data processed in the mobile terminal 100 through the wearable device. For example, according thereto, when a call is received by the mobile terminal 100, a user may perform a phone call through the wearable device or when a message is received by the mobile terminal 100, a user may check the received message.

[0086] The location information module 115 is a module for obtaining the location (or the current location) of a mobile terminal and its representative examples include a global positioning system (GPS) module or a Wi-Fi module. For example, the mobile terminal may obtain its position by using a signal transmitted from a GPS satellite through the GPS module. As another example, the mobile terminal may obtain its position on the basis of information of a wireless access point (AP) transmitting/receiving a wireless signal to/from the Wi-Fi module, through the Wi-Fi module. If necessary, the position information module 115 may perform a function of another module in the wireless communication unit 110 in order to obtain data on the location of the mobile terminal substitutionally or additionally. The location information module 115 is a module for obtaining the position (or the current position) of the mobile terminal and is not limited to a module directly calculating and obtaining the position of the mobile terminal.

[0087] Then, the input unit 120 is used for inputting image information (or signal), audio information (or signal), data, or information inputted from a user and the mobile terminal 100 may include at least one camera 121 in order for inputting image information. The camera 121 processes image frames such as a still image or a video obtained by an image sensor in a video call mode or a capturing mode. The processed image frame may be displayed on the display unit 151 or stored in the memory 170. Moreover, a plurality of cameras 121 equipped in the mobile terminal 100 may be arranged in a matrix structure and through the camera 121 having such a matrix structure, a plurality of image information having various angles or focuses may be inputted to the input terminal 100. Additionally, the plurality of cameras 121 may be arranged in a stereo structure to obtain the left and right images for implementing a three-dimensional image.

[0088] The microphone 122 processes external sound signals as electrical voice data. The processed voice data may be utilized variously according to a function (or an application program being executed) being performed in the mobile terminal 100. Moreover, various noise canceling algorithms for removing noise occurring during the reception of external sound signals may be implemented in the microphone 122.

[0089] The user input unit 123 is to receive information from a user and when information is inputted through the user input unit 123, the control unit may control an operation of the mobile terminal 100 to correspond to the inputted information. The user input unit 123 may include a mechanical input means (or a mechanical key, for example, a button, a dome switch, a jog wheel, and a jog switch at the front, back or side of the mobile terminal 100) and a touch type input means. As one example, a touch type input means may include a virtual key, a soft key, or a visual key, which is displayed on a touch screen through software processing or may include a touch key disposed at a portion other than the touch screen. Moreover, the virtual key or visual key may have various forms and may be disposed on a touch screen and for example, may include graphic, text, icon, video, or a combination thereof.

[0090] Moreover, the sensing unit 140 may sense at least one of information in a mobile terminal, environmental information around a mobile terminal, and user information and may then generate a sensing signal corresponding thereto. On the basis of such a sensing signal, the control unit 180 may control the drive or control of the mobile terminal 100 or may perform data processing, functions, or operations relating to an application program installed in the mobile terminal 100. Representative sensors among various sensors included in the sensing unit 140 will be described in more detail.

[0091] First, the proximity sensor 141 refers to a sensor detecting whether there is an object approaching a predetermined detection surface or whether there is an object around by using the strength of an electromagnetic field or infrared, without mechanical contact. The proximity sensor 141 may disposed in an inner area of a mobile terminal surrounded by the touch screen or around the touch screen.

[0092] Examples of the proximity sensor 141 may include a transmission-type photoelectric sensor, a direct reflective-type photoelectric sensor, a mirror reflective-type photoelectric sensor, a high-frequency oscillation-type proximity sensor, a capacitive-type proximity sensors, a magnetic-type proximity sensor, and an infrared proximity sensor. If the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of an object by changes in an electric field according to the proximity of the object having conductivity. In this case, the touch screen (or a touch sensor) itself may be classified as a proximity sensor.

[0093] Moreover, for convenience of description, an action for recognizing the position of an object on the touch screen as the object is close to the touch screen without contacting the touch screen is called “proximity touch” and an action that the object actually contacts the touch screen is called “contact touch”. A position that an object is proximity-touched on the touch screen is a position that the object vertically corresponds to the touch screen when the object is proximity-touched. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). Moreover, the control unit 180 processes data (for information) corresponding to a proximity touch operation and a proximity touch pattern, detected through the proximity sensor 141, and furthermore, may output visual information corresponding to the processed data on the touch screen. Furthermore, according to whether a touch for the same point on the touch screen is a proximity touch or a contact touch, the control unit 180 may control the mobile terminal 100 to process different operations or data (or information).

[0094] The touch sensor detects a touch (or a touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods, for example, a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method.

[0095] For example, the touch sensor may be configured to convert a pressure applied to a specific portion of the touch screen or changes in capacitance occurring at a specific portion into electrical input signals. The touch sensor may be configured to detect a position and area that a touch target applying a touch on the touch screen touches the touch sensor, a pressured when touched, and a capacitance when touched. Here, the touch target, as an object applying a touch on the touch sensor, may be a finger, a touch pen, a stylus pen, or a pointer, for example.

[0096] In such a manner, when there is a touch input on the touch sensor, signal(s) corresponding thereto are sent to a touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the control unit 180. Therefore, the control unit 180 may recognize which area of the display unit 151 is touched. Herein, the touch controller may be an additional component separated from the control unit 180 or may be the control unit 180 itself.

[0097] Moreover, the control unit 180 may perform different controls or the same control according to types of a touch target touching the touch screen (or a touch key equipped separated from the touch screen). Whether to perform different controls or the same control according to types of a touch target may be determined according to a current operation state of the mobile terminal 100 or an application program in execution.

[0098] Moreover, the above-mentioned touch sensor and proximity sensor are provided separately or combined and may thus sense various types of touches, for example, short (or tap) touch), long touch, multi touch, drag touch, flick touch, pinch-in touch, pinch-out touch, swipe touch, and hovering touch for the touch screen.

[0099] The ultrasonic sensor may recognize position information of a detection target by using ultrasonic waves. Moreover, the control unit 180 may calculate the position of a wave source through information detected by an optical sensor and a plurality of ultrasonic sensors. The position of the wave source may be calculated by using the property that light is much faster than ultrasonic wave, that is, a time that light reaches an optical signal is much shorter than a time that ultrasonic wave reaches an ultrasonic sensor. In more detail, the position of the wave source may be calculated by using a time difference with a time that ultrasonic wave reaches by using light as a reference signal.

[0100] Moreover, the camera 121 described as a configuration of the input unit 120 may include at least one of a camera sensor (for example, CCD and CMOS), a photo sensor (or an image sensor), and a laser sensor.

[0101] The camera 121 and the laser sensor may be combined to detect a touch of a detection target for a three-dimensional image. The photo sensor may be stacked on a display device and is configured to scan a movement of a detection target close to the touch screen. In more detail, the photo sensor mounts a photo diode and a transistor (TR) in a row/column and scans content disposed on the photo sensor by using an electrical signal changing according to an amount of light applied to the photo diode. That is, the photo sensor may calculate the coordinates of a detection target according to the amount of change in light and through this, may obtain the position information of the detection target.

[0102] The display unit 151 may display (output) information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program running on the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information according to such execution screen information.

[0103] Additionally, the display unit 151 may be configured as a three-dimensional display unit displaying a three-dimensional image.

[0104] A three-dimensional display method, for example, a stereoscopic method (a glasses method), an autostereoscopic (no glasses method), a projection method (a holographic method) may be applied to the three-dimensional display unit.

[0105] The sound output unit 152 may output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception or call mode, a recording mode, a voice recognition mode, or a broadcast reception mode. The sound output unit 152 may output a sound signal relating to a function (for example, a call signal reception sound and a message reception sound) performed by the mobile terminal 100. The sound output unit 152 may include a receiver, a speaker, and a buzzer.
