DETAILED DESCRIPTION

Arrangements and embodiments may now be described more fully with reference to the accompanying drawings, in which exemplary embodiments may be shown. Embodiments may, however, be embodied in many different forms and should not be construed as being limited to embodiments set forth herein; rather, embodiments may be provided so that this disclosure will be thorough and complete, and will fully convey the concept to those skilled in the art.

A mobile terminal may be described below with reference to the accompanying drawings. In the following description, suffixes “module” and “unit” may be given to components of the mobile terminal in consideration of only facilitation of description and do not have meanings or functions discriminated from each other.

The mobile terminal may include a cellular phone, a smart phone, a laptop computer, a digital broadcasting terminal, personal digital assistants (PDA), a portable multimedia player (PMP), a navigation system and/or so on.

FIG. 1 is a block diagram of a mobile terminal according to an embodiment. Other embodiments, configurations and arrangements may also be provided.

As shown, the mobile terminal 100 may include a wireless communication unit 110 (or radio communication unit), an audio/video (A/V) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface 170, a controller 180, and a power supply 190. The components shown in FIG. 1 may be essential parts and/or a number of components included in the mobile terminal 100 may vary. Components of the mobile terminal 100 may now be described.

The wireless communication unit 110 may include at least one module that enables radio communication between the mobile terminal 100 and a radio communication system or between the mobile terminal 100 and a network in which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include a broadcasting receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short range communication module 114 (or local area communication module), and a location information module 115 (or position information module).

The broadcasting receiving module 111 may receive broadcasting signals and/or broadcasting related information from an external broadcasting management server through a broadcasting channel. The broadcasting channel may include a satellite channel and a terrestrial channel, and the broadcasting management server may be a server that generates and transmits broadcasting signals and/or broadcasting related information or a server that receives previously created broadcasting signals and/or broadcasting related information and transmits the broadcasting signals and/or broadcasting related information to a terminal.

The broadcasting signals may include not only TV broadcasting signals, radio broadcasting signals, and data broadcasting signals but also signals in the form of a combination of a TV broadcasting signal and a radio broadcasting signal. The broadcasting related information may be information on a broadcasting channel, a broadcasting program or a broadcasting service provider, and may be provided even through a mobile communication network. In the latter case, the broadcasting related information may be received by the mobile communication module 112.

The broadcasting related information may exist in various forms. For example, the broadcasting related information may exist in the form of an electronic program guide (EPG) of a digital multimedia broadcasting (DMB) system or in the form of an electronic service guide (ESG) of a digital video broadcast-handheld (DVB-H) system.

The broadcasting receiving module 111 may receive broadcasting signals using various broadcasting systems. More particularly, the broadcasting receiving module 111 may receive digital broadcasting signals using digital broadcasting systems such as a digital multimedia broadcasting-terrestrial (DMB-T) system, a digital multimedia broadcasting-satellite (DMB-S) system, a media forward link only (MediaFLO) system, a DVB-H and integrated services digital broadcast-terrestrial (ISDB-T) systems. The broadcasting receiving module 111 may receive signals from broadcasting systems providing broadcasting signals other than the above-described digital broadcasting systems.

The broadcasting signals and/or broadcasting related information received through the broadcasting receiving module 111 may be stored in the memory 160. The mobile communication module 112 may transmit/receive a radio signal to/from at least one of a base station, an external terminal and a server on a mobile communication network. The radio signal may include a voice call signal, a video telephony call signal or data in various forms according to transmission and reception of text/multimedia messages.

The wireless Internet module 113 may correspond to a module for wireless Internet access and may be included in the mobile terminal 100 or may be externally attached to the mobile terminal 100. Wireless LAN (WLAN or Wi-Fi), wireless broadband (Wibro), world interoperability for microwave access (Wimax), high speed downlink packet access (HSDPA) and so on may be used as a wireless Internet technique.

The short range communication module 114 may correspond to a module for short range communication. Further, Bluetooth®, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB) and/or ZigBee® may be used as a short range communication technique.

The location information module 115 may confirm or obtain a location or a position of the mobile terminal 100. The location information module 115 may obtain position information by using a global navigation satellite system (GNSS). The GNSS is a terminology describing a radio navigation satellite system that revolves around the earth and transmits reference signals to predetermined types of radio navigation receivers such that the radio navigation receivers can determine their positions on the earth's surface or near the earth's surface. The GNSS may include a global positioning system (GPS) of the United States, Galileo of Europe, a global orbiting navigational satellite system (GLONASS) of Russia, COMPASS of China, and a quasi-zenith satellite system (QZSS) of Japan, for example.

A global positioning system (GPS) module is a representative example of the location information module 115. The GPS module may calculate information on distances between one point or object and at least three satellites and information on a time when distance information is measured and apply trigonometry to the obtained distance information to obtain three-dimensional position information on the point or object according to latitude, longitude and altitude at a predetermined time.

A method of calculating position and time information using three satellites and correcting the calculated position and time information using another satellite may also be used. Additionally, the GPS module may continuously calculate a current position in real time and calculate velocity information using the location or position information.

The A/V input unit 120 may input (or receive) an audio signal and/or a video signal. The A/V input unit 120 may include a camera 121 and a microphone 122. The camera 121 may process image frames of still images or moving images obtained by an image sensor in a video telephony mode or a photographing mode. The processed image frames may be displayed on a display 151, which may be a touch screen.

The image frames processed by the camera 121 may be stored in the memory 160 or may be transmitted to an external device through the wireless communication unit 110. The mobile terminal 100 may also include at least two cameras 121.

The microphone 122 may receive an external audio signal in a call mode, a recording mode and/or a speech recognition mode, and the microphone 122 may process the received audio signal into electric audio data. The audio data may then be converted into a form that can be transmitted to a mobile communication base station through the mobile communication module 112 and output in the call mode. The microphone 122 may employ various noise removal algorithms (or noise canceling algorithm) for removing or reducing noise generated when the external audio signal is received.

The user input unit 130 may receive input data for controlling operation of the mobile terminal 100 from a user. The user input unit 130 may include a keypad, a dome switch, a touch pad (constant voltage/capacitance), a jog wheel, a jog switch and/or so on.

The sensing unit 140 may sense a current state of the mobile terminal 100, such as an open/close state of the mobile terminal 100, a position of the mobile terminal 100, whether a user touches the mobile terminal 100, a direction of the mobile terminal 100, and acceleration/deceleration of the mobile terminal 100, and the sensing unit 140 may generate a sensing signal for controlling operation of the mobile terminal 100. For example, in an example of a slide phone, the sensing unit 140 may sense whether the slide phone is opened or closed. Further, the sensing unit 140 may sense whether the power supply 190 supplies power and/or whether the interface 170 is connected to an external device. The sensing unit 140 may also include a proximity sensor 141. The sensing unit 140 may sense a motion of the mobile terminal 100.

The output unit 150 may generate visual, auditory and/or tactile output, and the output unit 150 may include the display 151, an audio output module 152, an alarm 153 and a haptic module 154. The display 151 may display information processed by the mobile terminal 100. The display 151 may display a user interface (UI) and/or a graphic user interface (GUI) related to a telephone call when the mobile terminal 100 is in the call mode. The display 151 may also display a captured and/or received image, a UI or a GUI when the mobile terminal 100 is in the video telephony mode or the photographing mode.

The display 151 may include at least one of a liquid crystal display, a thin film transistor liquid crystal display, an organic light-emitting diode display, a flexible display and/or a three-dimensional display. The display 151 may be of a transparent type or a light transmissive type. That is, the display 151 may include a transparent display.

The transparent display may be a transparent liquid crystal display. A rear structure of the display 151 may also be of a light transmissive type. Accordingly, a user may see an object located behind the body (of the mobile terminal 100) through the transparent area of the body of the mobile terminal 100 that is occupied by the display 151.

The mobile terminal 100 may also include at least two displays 151. For example, the mobile terminal 100 may include a plurality of displays 151 that are arranged on a single face at a predetermined distance or integrated displays. The plurality of displays 151 may also be arranged on different sides.

When the display 151 and a sensor sensing touch (hereafter referred to as a touch sensor) form a layered structure that is referred to as a touch screen, the display 151 may be used as an input device in addition to an output device. The touch sensor may be in the form of a touch film, a touch sheet, and/or a touch pad, for example.

The touch sensor may convert a variation in pressure applied to a specific portion of the display 151 or a variation in capacitance generated at a specific portion of the display 151 into an electric input signal. The touch sensor may sense pressure of touch as well as position and area of the touch.

When the user applies a touch input to the touch sensor, a signal corresponding to the touch input may be transmitted to a touch controller. The touch controller may then process the signal and transmit data corresponding to the processed signal to the controller 180. Accordingly, the controller 180 may detect a touched portion of the display 151.

The proximity sensor 141 (of the sensing unit 140) may be located in an internal region of the mobile terminal 100, surrounded by the touch screen, and/or near the touch screen. The proximity sensor 141 may sense an object approaching a predetermined sensing face or an object located near the proximity sensor 141 using an electromagnetic force or infrared rays without having mechanical contact. The proximity sensor 141 may have a lifetime longer than a contact sensor and may thus have a wide application in the mobile terminal 100.

The proximity sensor 141 may include a transmission type photo-electric sensor, a direct reflection type photo-electric sensor, a mirror reflection type photo-electric sensor, a high-frequency oscillating proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and/or an infrared proximity sensor. A capacitive touch screen may be constructed such that proximity of a pointer is detected through a variation in an electric field according to the proximity of the pointer. The touch screen (touch sensor) may be classified as a proximity sensor 141.

For ease of explanation, an action of the pointer approaching the touch screen without actually touching the touch screen may be referred to as a proximity touch and an action of bringing the pointer into contact with the touch screen may be referred to as a contact touch. The proximity touch point of the pointer on the touch screen may correspond to a point of the touch screen at which the pointer is perpendicular to the touch screen.

The proximity sensor 141 may sense the proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch velocity, a proximity touch time, a proximity touch position, a proximity touch moving state, etc.). Information corresponding to the sensed proximity touch action and proximity touch pattern may then be displayed on the touch screen.

The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal receiving mode, a telephone call mode or a recording mode, a speech recognition mode and a broadcasting receiving mode. The audio output module 152 may output audio signals related to functions, such as a call signal incoming tone and a message incoming tone, performed in the mobile terminal 100. The audio output module 152 may include a receiver, a speaker, a buzzer, and/or the like. The audio output module 152 may output sounds through an earphone jack. The user may hear the sounds by connecting an earphone to the earphone jack.

The alarm 153 may output a signal for indicating generation of an event of the mobile terminal 100. For example, an alarm may be generated when receiving a call signal, receiving a message, inputting a key signal, and/or inputting a touch. The alarm 153 may also output signals in forms different from video signals or audio signals, for example, a signal for indicating generation of an event through vibration. The video signals and/or the audio signals may also be output through the display 151 or the audio output module 152.

The haptic module 154 may generate various haptic effects that the user can feel. One example of the haptic effects is vibration. An intensity and/or pattern of vibration generated by the haptic module 154 may also be controlled. For example, different vibrations may be combined and output or may be sequentially output.

The haptic module 154 may generate a variety of haptic effects including an effect of stimulus according to an arrangement of pins vertically moving against a contact skin surface, an effect of stimulus according to a jet force or sucking force of air through a jet hole or a sucking hole, an effect of stimulus of rubbing the skin, an effect of stimulus according to contact of an electrode, an effect of stimulus using an electrostatic force, and an effect according to a reproduction of cold and warmth using an element capable of absorbing or radiating heat in addition to vibrations.

The haptic module 154 may not only transmit haptic effects through direct contact but may also allow the user to feel haptic effects through a kinesthetic sense of the user's fingers or arms. The mobile terminal 100 may also include a plurality of haptic modules 154.

The memory 160 may store a program for operations of the controller 180 and/or temporarily store input/output data such as a phone book, messages, still images, and/or moving images. The memory 160 may also store data about vibrations and sounds in various patterns that are output from when a touch input is applied to the touch screen.

The memory 160 may include at least a flash memory, a hard disk type memory, a multimedia card micro type memory, a card type memory, such as SD or XD memory, a random access memory (RAM), a static RAM (SRAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), a programmable ROM (PROM) magnetic memory, a magnetic disk and/or an optical disk. The mobile terminal 100 may also operate in relation to a web storage that performs a storing function of the memory 160 on the Internet.

The interface 170 may serve as a path to external devices connected to the mobile terminal 100. The interface 170 may receive data from the external devices or power and transmit the data or power to internal components of the mobile terminal 100 or transmit data of the mobile terminal 100 to the external devices. For example, the interface 170 may include a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for connecting a device having a user identification module, an audio I/O port, a video I/O port, and/or an earphone port.

The interface 170 may also interface with a user identification module that is a chip that stores information for authenticating authority to use the mobile terminal 100. For example, the user identification module may be a user identify module (UIM), a subscriber identify module (SIM) and/or a universal subscriber identify module (USIM). An identification device (including the user identification module) may also be manufactured in the form of a smart card. Accordingly, the identification device may be connected to the mobile terminal 100 through a port of the interface 170.

The interface 170 may also be a path through which power from an external cradle is provided to the mobile terminal 100 when the mobile terminal 100 is connected to the external cradle or a path through which various command signals input by the user through the cradle are transmitted to the mobile terminal 100. The various command signals or power input from the cradle may be used as signals for confirming whether the mobile terminal 100 is correctly set in the cradle.

The controller 180 may control overall operations of the mobile terminal 100. For example, the controller 180 may perform control and processing for voice communication, data communication and/or video telephony. The controller 180 may also include a multimedia module 181 for playing multimedia. The multimedia module 181 may be included in the controller 180 or may be separated from the controller 180.

The controller 180 may perform a pattern recognition process capable of recognizing handwriting input or picture-drawing input applied to the touch screen as characters or images. The power supply 190 may receive external power and internal power and provide power required for operations of the components of the mobile terminal 100 under control of the controller 180.

According to hardware implementation, embodiments may be implemented using at least one of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, and/or electrical units for executing functions. Embodiments may be implemented by the controller 180.

According to software implementation, embodiments such as procedures or functions may be implemented with a separate software module that executes at least one function or operation. Software codes may be implemented according to a software application written in an appropriate software language. The software codes may be stored in the memory 160 and executed by the controller 180.

FIG. 2A is a front perspective view of a mobile terminal (or a handheld terminal) according to an embodiment.

The mobile terminal 100 may be a bar type terminal body. However, embodiments are not limited to a bar type terminal and may be applied to terminals of various types including slide type, folder type, swing type and/or swivel type terminals having at least two bodies that are relatively movably combined.

The terminal body may include a case (a casing, a housing, a cover, etc.) that forms an exterior of the mobile terminal 100. In this embodiment, the case may be divided into a front case 101 and a rear case 102. Various electronic components may be arranged in the space formed between the front case 101 and the rear case 102. At least one middle case may be additionally provided between the front case 101 and the rear case 102.

The cases may be formed of plastics through injection molding or made of a metal material such as stainless steel (STS) or titanium (Ti).

The display 151, the audio output unit 152, the camera 121, the user input unit 130/131 and 132, the microphone 122 and the interface 170 may be arranged (or provided) in the terminal body, and more specifically may be arranged (or provided) in the front case 101.

The display 151 may occupy most of the main face of the front case 101. The audio output unit 152 and the camera 121 may be arranged in a region in proximity to one of both ends of the display 151 and the user input unit 131, and the microphone 122 may be located in a region in proximity to another end of the display 151. The user input unit 132 and the interface 170 may be arranged (or provided) on sides of the front case 101 and the rear case 102.

The user input unit 130 may receive commands for controlling operation of the mobile terminal 100, and may include a plurality of operating units 131 and 132. The operating units 131 and 132 may be referred to as manipulating portions and may employ any tactile manner in which a user operates the operating units 131 and 132 while having tactile feeling.

The first and second operating units 131 and 132 may receive various inputs. For example, the first operating unit 131 may receive commands such as start, end and scroll and the second operating unit 132 may receive commands such as control of a volume of sound output from the audio output unit 152 or conversion of the display 151 to a touch recognition mode.

FIG. 2B is a rear perspective view of the mobile terminal (shown in FIG. 2A) according to an embodiment.

Referring to FIG. 2A, a camera 121′ may be additionally attached to the rear side of the terminal body (i.e., the rear case 102). The camera 121′ may have a photographing direction opposite to that of the camera 121 (shown in FIG. 2A) and may have pixels different from those of the camera 121 (shown in FIG. 2A).

For example, it may be desirable that the camera 121 has low pixels such that the camera 121 may capture an image of a face of a user and transmit the image to a receiving part in case of video telephony while the camera 121′ has high pixels because the camera 121′ captures an image of a general object and does not immediately transmit the image in many cases. The cameras 121 and 121′ may be attached (or provided) to the terminal body such that the cameras 121 and 121′ may rotate or pop-up.

A flash bulb 123 and a mirror 124 may be additionally provided in proximity to the camera 121′. The flash bulb 123 may light an object when the camera 121′ takes a picture of the object. The mirror 124 may be used for the user to look at his/her face in the mirror when the user wants to self-photograph himself/herself using the camera 121′.

An audio output unit 152′ may be additionally provided on the rear side of the terminal body. The audio output unit 152′ may achieve a stereo function with the audio output unit 152 (shown in FIG. 2A) and may be used for a speaker phone mode when the terminal is used for a telephone call.

A broadcasting signal receiving antenna may be additionally attached (or provided) to the side of the terminal body in addition to an antenna for telephone calls. The antenna constructing a part of the broadcasting receiving module 111 (shown in FIG. 1) may be set in the terminal body such that the antenna may be pulled out of the terminal body.

The power supply 190 for providing power to the mobile terminal 100 may be set in the terminal body. The power supply 190 may be included in the terminal body or may be detachably attached to the terminal body.

A touch pad 135 for sensing touch may be attached to the rear case 102. The touch pad 135 may be of a light transmission type, such as the display 151. In this example, if the display 151 outputs visual information through both sides thereof, the visual information may be recognized (or determined) by the touch pad 135. The information output through both sides of the display 151 may be controlled by the touch pad 135. Otherwise, a display may be additionally attached (or provided) to the touch pad 135 such that a touch screen may be arranged (or provided) even in the rear case 102.

The touch pad 135 may operate in connection with the display 151 of the front case 101. The touch pad 135 may be located in parallel with the display 151 behind the display 151. The touch panel 135 may be identical to or smaller than the display 151 in size.

FIG. 3 is a view for explaining a proximity depth of a proximity sensor.

As shown in FIG. 3, when a pointer (such as a user's finger) approaches the touch screen, the proximity sensor located inside or near the touch screen may sense the approach of the pointer, and may output a proximity signal.

The proximity sensor may be constructed such that the proximity sensor outputs a proximity signal according to a distance between the pointer approaching the touch screen and the touch screen (referred to as “proximity depth”).

The distance in which the proximity signal is output when the pointer approaches the touch screen may be referred to as a detection distance. The proximity depth may be determined by using a plurality of proximity sensors having different detection distances and by comparing proximity signals respectively output from the proximity sensors.

FIG. 3 shows a section of the touch screen in which proximity sensors capable of sensing three proximity depths may be provided. Proximity sensors capable of sensing less than three or more than four proximity depths may be provided in the touch screen.

More specifically, when the pointer completely contacts the touch screen (D0), it may be recognized as contact touch. When the pointer is located within a distance D1 from the touch screen, it may be recognized as a proximity touch of a first proximity depth. When the pointer is located in a range between the distance D1 and a distance D2 from the touch screen, it may be recognized as a proximity touch of a second proximity depth. When the pointer is located in a range between the distance D2 and a distance D3 from the touch screen, it may be recognized as a proximity touch of a third proximity depth. When the pointer is located greater than the distance D3 from the touch screen, it may be recognized as cancellation of the proximity touch.

Accordingly, the controller 180 may recognize the proximity touch as various input signals according to proximity distance and proximity position of the pointer with respect to the touch screen, and the controller 810 may perform various operation controls according to the input signals.

FIG. 4 is a flowchart illustrating operations of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 4, the controller 180 of the mobile terminal 100 according to an embodiment of the present invention may display an object (S10).

The object may be displayed on the display 151 and visually recognized by a user. There may be various objects. For example, an object can be a video and/or a still image captured by the camera 121, or a video and/or a still image acquired from an external device. Otherwise, the object may be content generated by the user of the mobile terminal 100. That is, the object may be a figure, a picture, a character or the like input by the user.

An object may be displayed on the display 151 on the basis of operation of the user and/or control operation of the controller 180. For example, the user can select content and display the selected content on the display. At the instant the content is displayed, the content can be regarded as a visually recognizable object.

When the object is displayed, a first touch applied to the object may be acquired (S20).

The first touch may be a touch operation performed on the displayed object. For example, the first touch can be an operation of touching an area in which the object is displayed with a finger. In this case, the touch operation may be an operation of touching a point in the area in which the object is displayed and holding the touch.

The first touch may be a series of touch operations simultaneously or sequentially performed. For example, when a plurality of objects are displayed, the first touch can be operations of touching a first object with a first finger and touching a second object with a second finger while maintaining the touch applied to the first object. Otherwise, the first touch can be an operation of touching the second object within a predetermined time after touch of the first object is ended.

A second touch applied to the display 151 may be acquired (S30).

The second touch may be different from the first touch. For example, the second touch can be a touch operation performed on the outside of the area in which the object is displayed. The second touch may be various types of touch operations. For example, the second touch can include short touch applied to a specific point, long touch applied to a specific point, drag touch, flicking touch, double touch applied to a specific point, double touch simultaneously applied to two points.

Display of the object may be changed according to the attribute of the object and the attribute of the second touch (S40).

The controller 180 can change display of the object. For example, the controller 180 can change at least one of the position, size and color of the object. Otherwise, the controller 180 can cancel display of the object.
