Description

MOBILE TERMINAL AND METHOD FOR CONTROLLING THE SAME

Terminals may be divided into mobile/portable terminals and stationary terminals according to their mobility. Also, the mobile terminals may be classified into handheld terminals and vehicle mount terminals according to whether or not a user can directly 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. Specifically, in recent time, mobile terminals can receive broadcast and multicast signals to allow viewing of video or television programs.

As it becomes multifunctional, a mobile terminal can be allowed to capture still images or moving images, play music or video files, play games, receive broadcast and the like, so as to be implemented as an integrated multimedia player.

The mobile terminal 100 may be configured to utilize information obtained from sensing unit 140, and in particular, information obtained from one or more sensors of the sensing unit 140, and combinations thereof.

The output unit 150 may be configured to output various types of information, such as audio, video, tactile output, and the like. The output unit 150 may be shown having a display unit 151, an audio output module 152, a haptic module 153, and an optical output module 154. The display unit 151 may have an inter-layered structure or an integrated structure with a touch sensor in order to facilitate a touch screen. The touch screen may provide an output interface between the mobile terminal 100 and a user, as well as function as the user input unit 123 which provides an input interface between the mobile terminal 100 and the user.

The interface unit 160 serves as an interface with various types of external devices that can be coupled to the mobile terminal 100. The interface unit 160, for example, may include any of wired or wireless 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, and the like. In some cases, the mobile terminal 100 may perform assorted control functions associated with a connected external device, in response to the external device being connected to the interface unit 160.

The memory 170 is typically implemented to store data to support various functions or features of the mobile terminal 100. For instance, the memory 170 may be configured to store application programs executed in the mobile terminal 100, data or instructions for operations of the mobile terminal 100, and the like. Some of these application programs may be downloaded from an external server via wireless communication. Other application programs may be installed within the mobile terminal 100 at time of manufacturing or shipping, which is typically the case for basic functions of the mobile terminal 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the mobile terminal 100, and executed by the controller 180 to perform an operation (or function) for the mobile terminal 100.

The controller 180 typically functions to control overall operation of the mobile terminal 100, in addition to the operations associated with the application programs. The controller 180 may provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 1A, or activating application programs stored in the memory 170.

As one example, the controller 180 controls some or all of the components illustrated in FIGS. 1A according to the execution of an application program that have been stored in the memory 170. Also, the controller 180 may operate at least two components included in the mobile terminal in a combining manner to activate the application program.

The power supply unit 190 can be configured to receive external power or provide internal power, under the control of the controller, in order to supply appropriate power required for operating elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, and the battery may be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.

At least some of those components may be combined for operation to implement an operation, a control or a control method of the mobile terminal according to various embodiments disclosed herein. Also, the operation, the control or the control method of the mobile terminal may be implemented on the mobile terminal by activating at least one application program stored in the memory 170.

Hereinafter, prior to describing various exemplary embodiments implemented by the mobile terminal 100, each of the aforementioned components will be described in more detail with reference to FIG. 1A.

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 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), Enhanced Voice-Date 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) , LTE-advanced (LTE-A) and the like).

Examples of the wireless signals 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), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE) , LTE-advanced (LTE-A) 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 may include BLUETOOTHTM, 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. 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. If necessary, the location information module 115 may perform a function of another module of the wireless communication unit 110, in order to obtain data associated with a location of the mobile terminal in a replacing manner or an additional manner. The location information module 115 is a module used for acquiring a location (or a current location) of the mobile terminal, and may not be limited to a module which directly calculates or acquires the location of the mobile terminal.

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 processes an external audio signal into electric audio data. The processed audio data may be utilized in various manners according to a currently-executed function (or a currently-executed application program) in the mobile terminal 100. Meanwhile, 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 or a mechanical key (for example, 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 element, among others. As one example, the touch-sensitive input element may be a virtual key, a soft key or a visual 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 refers to 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 (or touch input) applied to the touch screen, such as the 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, which has been depicted as a component of the input unit 120, typically includes at least one of 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.

Also, 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.

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’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 alarm, 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 type, a hard disk type, a solid state disk (SSD) type, a silicon disk drive (SDD) type, 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.

As aforementioned, the controller 180 controls the operations associated with the application programs and typically controls 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.

Here, considering the mobile terminal 100 as at least one set, the terminal body may be understood as a conception referring to the set.

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 151a 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 121b or an audio output module 152b.

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 151a 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.

The mobile terminal 100 may include a display unit 151, first and second

audio output module

152a and 152b, a proximity sensor 141, an illumination sensor 142, an optical output module 154, first and

second cameras

121a and 121b, first and

second manipulation units

123a and 123b, a microphone 122, an interface unit 160, and the like.

Hereinafter, as illustrated in FIGS. 1B and 1C, description will be given of the exemplary mobile terminal 100 in which the front surface of the terminal body is shown having the display unit 151, the first audio output module 152a, the proximity sensor 141, the illumination sensor 142, the optical output module 154, the first camera 121a, and the first manipulation unit 123a, the side surface of the terminal body is shown having the second manipulation unit 123b, the microphone 122, and the interface unit 160, and the rear surface of the terminal body is shown having the second audio output module 152b and the second camera 121b.

However, those components may not be limited to the arrangement. Some components may be omitted or rearranged or located on different surfaces. For example, the first manipulation unit 123a may be located on another surface of the terminal body, and the second audio output module 152b may be located on the side surface of the terminal body other than the rear surface of the terminal body.

The display unit 151 outputs 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.

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 151a and a display on a rear surface of the window 151a, or a metal wire which is patterned directly on the rear surface of the window 151a. 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 123a.

The first audio output module 152a may be implemented in the form of a receiver for transferring call sounds to a user’s ear and the second audio output module 152b may be implemented in the form of a loud speaker to output alarm sounds, multimedia audio reproduction, and the like.

The window 151a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152a 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 151a 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 alarm, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller 180 can control the optical output module 154 to stop the light output.

The first camera 121a 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

123a and 123b 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

123a and 123b 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

123a and 123b 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 123a as a touch key, but possible alternatives include a push (or mechanical) key, a touch key, and combinations thereof.

Input received at the first and

second manipulation units

123a and 123b may be used in various ways. For example, the first manipulation unit 123a 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 123b 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

152a or 152b, 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

152a or 152b, 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.

When the rear input unit is provided on the rear surface of the terminal body, a new type of user interface using this can be implemented. Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123a in the rear input unit. As such, in situations where the first manipulation unit 123a 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’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 121b 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 121a.

The second camera 121b 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 121b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.

A flash 124 is shown adjacent to the second camera 121b. When an image of a subject is captured with the camera 121b, the flash 124 may illuminate the subject.

The second audio output module 152b can be located on the terminal body. The second audio output module 152b may implement stereophonic sound functions in conjunction with the first audio output module 152a, 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 (see FIG. 1A) 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.

Hereinafter, description will be given of related embodiments of a control method which can be implemented in the mobile terminal having such configuration with reference to the accompanying drawings. It will be understood by those skilled in the art that the present invention can be specified into other specific forms without departing from the spirit and essential features of the present invention.

As illustrated In FIG. 2, a keyword which is spoken (said) by a user with applying a preset gesture and a voice control command including the keyword are received from the user through the input unit 120 (S210).

In detail, the preset gesture may be various types of touches, such as 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. Or, the preset gesture may be an input applied by a mechanical key (or a push key) such as a home key or a back key.

The voice control command is a voice command for executing a specific control operation, and may include the keyword. The keyword refers to a word for extracting core data corresponding thereto.

For example, a user may speak a voice control command such as “Place a call to A.” Here, while speaking the keyword “A,” the user may apply a long touch to a specific icon.

In response to the input of the keyword spoken with applying the preset gesture and the voice control command including the keyword, core data corresponding to the keyword is extracted on the basis of relevant data that is detected in relation to the keyword (S220).

The relevant data may be data that is stored by the user in relation to the keyword and history data of events generated in a terminal 100.

In detail, the history data of the events refers to a list of events generated in the terminal for a preset time. For example, the history data of the events may include data transmitted and received in the terminal 100 for a preset time, data stored through a specific application, a user’s control command input under a specific situation, and the like.

The core data corresponding to the keyword may be defined as data that is extracted through an analysis of user intent on the basis of the relevant data.

For example, the user may input a voice control command, such as “Place a call to A” by applying a touch input to a specific icon while speaking a keyword “A.” Accordingly, the controller 180 may extract “B” as a real person indicated by “A” on the basis of previously transmitted and received messages and the like. That is, B is the core data corresponding to A.

Next, the extracted core data is output on the display unit 151 (S230).

For example, in response to an input of a first recipient, which is spoken by the user with applying a preset gesture, and a voice control command for communication with the first recipient, the controller 180 may extract data associated with a second recipient corresponding to the first recipient as the core data, on the basis of relevant data that is detected in relation to the first recipient, and control the display unit 151 to output the extracted data associated with the second recipient.

Here, the relevant data may include data stored by the user in relation to the first recipient, an ID of a chat counterpart registered in a messenger application, data transmitted and received through the messenger application, and the like.

The controller 180 may also execute a control operation for communicating with the second recipient, in response to a user input which is applied to confirm that the extracted data associated with the second recipient corresponds to the first recipient.

In another example, in response to an input of a first schedule, which is spoken by the user with applying a preset gesture, and a voice control command for transmitting a message relating to the first schedule to the first recipient, the controller 180 may extract a second schedule corresponding to the first schedule as the core data on the basis of relevant data that is detected in relation to the first schedule, and control the display unit 151 to output the extracted second schedule.

Here, the relevant data may include data, which has been stored in a schedule management application in correspondence with the first recipient or the date of the first schedule.

The controller 180 may also transmit a message relating to the second schedule to the first recipient, in response to a user input which is applied to confirm that the extracted second schedule corresponds to the first schedule.

In another example, the controller 180 may control the display unit 151 to output a message transmission history indicating that a message relating to the first schedule has been transmitted to the first recipient.

In another example, the controller 180 may extract the core data corresponding to the keyword upon the input of the voice control command, on the basis of a connection or disconnection between the terminal 100 and an external device, a level of external noise sensed in the terminal 100, a place where the terminal is currently present, a time when the voice control command is input, whether or not the user is holding (gripping, grasping) the terminal 100, and the like.

As aforementioned, in response to the input of the first recipient, which is spoken with applying the preset gesture, and the voice control command for communication with the first recipient, the controller 180 may extract the data associated with the second recipient corresponding to the first recipient as the core data, on the basis of relevant data that is detected in relation to the first recipient, and control the display unit 151 to output the extracted data associated with the second recipient.

For explaining this embodiment, it is assumed that A is stored as B in a phonebook of the terminal 100. That is, the different terms, names, or letters refer to actually the same person. For example, A is a name and B is a nickname.

As illustrated in FIG. 3, after activating a voice recognition mode, a user may speak a voice control command such as “Place a call to A” with applying a long touch input to a specific icon 310 while speaking a keyword “A” (first recipient).

Responsive to this, contents (text) 320 spoken by the user may be output on a screen 151, and the keyword may be output in a highlighting manner. For example, the keyword “A” may be output with a different color or font or underlined.

Meanwhile, the controller 180 may search for a phonebook. When A is not included in the phonebook according to the search result, the controller 180 may search for IDs registered in a messenger application. Accordingly, when A is searched for from the IDs registered in the messenger application, the controller 180 may then search for the same phone number as a phone number of A among phone numbers stored in the phonebook, so as to confirm that the phone number of A has been stored as a phone number of B in the phonebook. The controller 180 may thusly extract B as data corresponding to A, namely, can recognize that A and B are the same person.

In another example, the controller 180 may search for whether or not there is a person corresponding to A from data transmitted and received through the messenger application. In detail, when there is data in which B is called A among data transmitted to B, the controller 180 may extract B as the data corresponding to A.

In this manner, when B is extracted as the data corresponding to A, a message window 330 for asking whether or not to place a call to A may be output. Also, data 340 corresponding to A may be output. The data 340 may include a name (B) corresponding to A, a phone number of B corresponding to A, and the like.

In another example, when external devices are recognized near the terminal 100, the name (B) corresponding to A may be output for a short term of time. That is, only A may be output on the screen 151 after B is shown for a short term of time.

Afterwards, when the user who has recognized that A and B are the same person inputs a voice command or applies a touch input for confirming that A and B correspond to each other, a call is placed to the phone number of B stored in the phonebook. Accordingly, a screen 350 of dialing the phone number of B may be output, and a recipient may be indicated with A or B.

In another example, when a plurality of persons have been searched for as corresponding to A, a person who has transmitted and received a call or message the most recently may be extracted as data corresponding to A. Or, a screen for selecting one of the plurality of persons may be output.

According to the embodiment illustrated in FIG. 3, it can be derived that the user has spoken the voice control command to place a call to A but a control operation actually desired by the user is to place a call to B. Thus, a control operation based on an analysis of such user intent may be executed in the terminal 100.

That is, according to the related art, in order to place a call to A (B) by inputting a voice control command, the user should speak to place the call to B. In this instance, it is known to outside that A has been stored as B in a phonebook. On the contrary, according to the present invention, the fact that A has been stored as B in the phonebook cannot be known to outside.

Meanwhile, in response to an input of a first schedule, which is spoken with applying the preset gesture, and a voice control command for transmitting a message relating to the first schedule to a first recipient, the controller 180 may extract a second schedule corresponding to the first schedule as the core data on the basis of relevant data that is detected in relation to the first schedule, and control the display unit 151 to output the extracted second schedule.

Here, the relevant data may include data, which is stored in a schedule management application in correspondence with the first recipient or the date of the first schedule.

For explaining the embodiment, it is assumed that a schedule (second schedule) to go and play with A this evening has been stored in a schedule management application.

As illustrated in FIG. 4, after activating a voice recognition mode, a user may input a voice control command “Send a message to A to do homework together this evening,” with applying a long touch input to a specific icon 310 while speaking “Homework this evening” (first schedule) as a keyword.

Accordingly, contents 410 spoken by the user may be output on the screen 151, and the keyword may be output in a highlighting manner. For example, the keyword “Homework this evening” may be output with a different color or font or underlined.

In the meantime, the controller 180 may extract a second schedule to go and play with A this evening, from a schedule planned to do something with A or a schedule for this evening, stored in a schedule management application, chat messages transmitted and received with A through a messenger application, and the like, (i.e., relevant data detected in relation to a first schedule).

In this manner, when “Go and play this evening” (second schedule) is extracted as data corresponding to “Homework this evening” (first schedule), a message window 420 may be output to ask whether or not to send a message to A to go and play together this evening. Afterwards, when the user touches a send icon 430 for selection, the message to go and play this evening may be sent to A.

In another example, when a plurality of schedules corresponding to “Homework this evening” are searched for, a screen for selecting one of the plurality of schedules may be output.

In another example, the derived result (second schedule) may also be output through a voice along with the message window 420. In detail, when the user is wearing a headset, a voice “Do you want to send a message to A to ask for going and playing this evening?” may also be output. However, in a speaker mode, only a voice such as “Do you want to send a message like this?” may be output.

According to the embodiment illustrated in FIG. 4, the user has spoken the voice control command for transmitting the message to A to do homework together this evening. However, it can be derived that the user actually intends to transmit a message to go and play this evening to A , and thus a control operation based on an analysis of the user intent may be executed in the terminal 100.

That is, according to the related art, when the user desires to send a message to A to go and play this evening through an input of a voice control command, such schedule with A may be known to outside. However, according to the present invention, by speaking another schedule (the first schedule) to do homework this evening, the user can avoid a schedule to go and play with A this evening (the second schedule) from being known to outside due to the input of the voice control command. Simultaneously, a message relating to the real schedule (the second schedule) can be sent to A.

In an embodiment continued from FIG. 4, the controller 180 may control the display unit 151 to output a message transmission history indicating that the message relating to the first schedule has been sent to the first recipient.

FIGS. 5 and 6 and 6 are conceptual views illustrating a screen output on a user terminal in relation to the embodiment of FIG. 4. FIG. 7 is a conceptual view illustrating a screen output on a terminal of a counterpart in relation to the embodiment of FIG. 4.

As an embodiment continued from FIG. 4, referring to FIG. 5, a message window 500 for notifying that the message to do homework together this evening has been sent to A may be output on the screen 151. That is, the message to go and play together has actually been sent to A, but contents 500 that the user has actually spoken may be stored in the message transmission history.

Also, according to the embodiment of FIG. 4, the message to go and play together this evening is sent to a terminal 100-2 of A from the user’s terminal 100-1. However, referring to FIG. 6, it may be output on the user’s terminal 100-1 that a message 600 to do homework together this evening has been sent to A. Accordingly, the schedule (second schedule) to go and play with A this evening may be avoided from being recorded in the message transmission history.

On the other hand, referring to FIG. 7, the terminal 100-2 of A may output a message 700 to go and play together this evening, sent from the user, namely, the actually-received message.

As another example, the user may directly store relevant data for analyzing a keyword, namely, relevant data for analyzing user intent.

FIG. 8 is a conceptual view illustrating an embodiment of storing related data for analyzing user intent.

As illustrated in FIG. 8, B, C and D may be stored as data related to A. For example, A, B, C and D may be names, nicknames and the like of the same person. That is, even when the user has spoken one of A, B, C and D as the aforementioned keyword, the input voice control command may be executed by considering A, B, C and D as the same person. In detail, a phone number, an email and an ID of a messenger or SNS application belonging to A may also be recognized as data for B, C and D.

In an embodiment for storing the relevant data, when the user speaks B after touching a tag add icon 810, B 820 may be added as tag information relating to A. Here, an indicator 822 indicating that the tag information has been input through a voice may be output.

In another example, when the user inputs C after touching the tag add icon 810, C 830 may be added as the tag information relating to A. Here, an indicator 832 indicating that the tag information has been input through a text may be output.

In another example, when the controller 180 extracts D as the same person as A, D 840 may be added as the tag information relating to A. Here, an indicator 842 indicating that the tag information has been stored through an automatic extraction may be output. In detail, when the user places a call to A and A is called D by the user, D may be stored as the tag information relating to A.

The relevant data illustrated in FIG. 8 may be stored into a separate category, or may be the same data as data in the phonebook. That is, the tag information B, C and D may be stored in the phonebook.

Meanwhile, the controller 180 may extract the core data corresponding to the keyword upon the input of the voice control command, on the basis of a connection or disconnection between the terminal 100 and an external device, a level of external noise sensed in the terminal 100, a place where the terminal is currently present, a time when the voice control command is input, whether or not the user is holding (gripping, grasping) the terminal 100, and the like.

As illustrated in FIG. 9, when the user speaks “Volume” while watching a video, the terminal 100 may measure a level of ambient noise through the microphone 122 or the like. Here, the user may also apply a preset specific gesture simultaneously when speaking “Volume.” For example, the user may speak “Volume” while applying a proximity touch input obscuring a video playback screen 910.

Accordingly, when the level of the ambient noise of the terminal 100 is over a preset reference value, the volume of the video increases and a volume-up menu 920 is output. A degree of increasing the volume of the video may be differently set depending on the level of the ambient noise. For example, a higher volume may be set for the video with respect to the higher level of the ambient noise.

On the other hand, when the level of the ambient noise of the terminal 100 is lower than the preset reference value, the volume of the video decreases and a corresponding volume-down menu 930 is output. Similarly, the degree of decreasing the volume of the video may be differently set depending on the level of the ambient noise. For example, a lower volume may be set for the video with respect to the lower level of the ambient noise.

As illustrated in FIG. 10, a user may input a voice “A” after activating a voice recognition mode. Here, the user may speak “A” while applying a long touch input to a specific icon 1010.

Upon the input of the voice “A,” if the terminal 100 is in a state of being connected to a headset or an earphone, a music playback application may be executed and a music content A may be played back on the terminal 100. That is, a playback screen 1020 of the music content A is output on the screen 151.

However, when the terminal 100 is not in the state of being connected to the headset or the earphone, an Internet application may be executed on the terminal 100 and a screen 1030 may be output to show a search result of the music content A.

As illustrated in FIG. 11, a user may speak a name of an application desiring to execute, for example, “Email.” Here, the user may also apply a preset specific gesture while speaking “Email.” For example, the user can speak “Email” while applying a proximity touch input which obscures a home screen 1110.

Accordingly, when a place where the terminal is currently present is an office or a current time zone is a daytime, an email execution screen 1120 relevant to business affairs may be output. On the other hand, when a place where the terminal is currently present is another place, such as a home, other than the office or a current time zone is a nighttime, a personal email execution screen 1130 may be output.

As aforementioned, the representative example of the module for acquiring the position (or the current position) of the mobile terminal 100 is the GPS module or the WiFi module. For example, when the mobile terminal 100 uses the 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 100 uses the Wi-Fi module, a position of the mobile terminal 100 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. If necessary, the location information module 115 may perform a function of another module of the wireless communication unit 110, in order to obtain data associated with a location of the mobile terminal 100 in a replacing manner or an additional manner. The location information module 115 is a module used for acquiring a location (or a current location) of the mobile terminal 100, and may not be limited to a module which directly calculates or acquires the location of the mobile terminal.

As illustrated in FIG. 12, a user may input a voice “A” after activating a voice recognition mode. The voice “A” may be a name of a person which is stored in a phonebook of the terminal 100. Here, the user may speak “A” while applying a long touch input to a specific icon 1210.

Upon the input of the voice “A,” if the user is not holding the terminal 100, an execution screen 1220 of a message application to write a message to A may be output. On the other hand, when the user is holding the terminal 100, a call may be placed to A and a corresponding dialing screen 1230 may be output. Meanwhile, a gyro sensor or an acceleration sensor may be used to determine whether or not the user is holding the terminal 100.

The present invention can be implemented as computer-readable codes in a program-recorded medium. The computer-readable medium may include all types of recording devices each storing data readable by a computer system. Examples of such computer-readable media may include hard disk drive (HDD), solid state disk (SSD), silicon disk drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage element and the like. Also, the computer-readable medium may also be implemented as a format of carrier wave (e.g., transmission via an Internet). The computer may include the controller 180 of the mobile terminal. Therefore, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
