Such broadcast systems may include Digital Multimedia Broadcasting-Terrestrial (DMB-T), Digital Multimedia Broadcasting-Satellite (DMB-S), Media Forward Link Only (MediaFLO), Digital Video Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T) and the like. Of course, the broadcast receiving module 111 may be configured to be suitable for every broadcast system transmitting broadcast signals as well as the digital broadcasting systems.
Broadcast signals and/or broadcast associated information received via the broadcast receiving module 111 may be stored in a memory 160.
The mobile communication module 112 transmits and receives wireless signals to and from at least one a base station, an external terminal and a server on a mobile communication network. Here, the wireless signals may include audio call signals, video call signals, or various formats of data according to the transmission and reception of text/multimedia messages.

Referring to
The image frames processed by the camera 121 may be stored in the memory 160 or transmitted to an external device through the wireless communication unit 110. Furthermore, the user's location information or the like may be produced from image frames acquired from the camera 121. Two or more cameras 121 may be provided according to the use environment.
The microphone 122 receives an external audio signal through a microphone in a phone call mode, a recording mode, a voice recognition mode, and the like, and processes the audio signal into electrical voice data. The processed voice data may be converted and outputted into a format that is transmittable to a mobile communication base station through the mobile communication module 112 in the phone call mode. The microphone 122 may implement various types of noise canceling algorithms to cancel noise generated in a procedure of receiving the external audio signal.
The user input unit 130 may generate input data to control an operation of the terminal. The user input unit 130 may be configured by including a keypad, a dome switch, a touch pad (pressure/capacitance), a jog wheel, a jog switch, and the like.
The sensing unit 140 detects a current status of the mobile terminal 100 such as an opened or closed configuration of the mobile terminal 100, a location of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, an orientation of the mobile terminal 100, an acceleration/deceleration of the mobile terminal 100, and the like, so as to generate a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is a slide phone type, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include sensing functions, such as the sensing unit 140 sensing the presence or absence of power provided by the power supply unit 190, the presence or absence of a coupling between the interface unit 170 and an external device.
The output unit 150 is configured to generate an output associated with visual sense, auditory sense or tactile sense, and may include a display unit 151, an audio output module 153, an alarm unit 154, a haptic module 155, and the like.
The display unit 151 may display (output) information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphic User Interface (GUI) associated with a call. When the mobile terminal 100 is in a video call mode or image capturing mode, the display unit 151 may display a captured image and/or received image, a UI or GUI.
The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and an e-ink display.
Some of those displays may be configured with a transparent or optical transparent type to allow viewing of the exterior through the display unit, which may be called transparent displays. An example of the typical transparent displays may include a transparent LCD (TOLED), and the like. Under this configuration, a user can view an object positioned at a rear side of a mobile terminal body through a region occupied by the display unit 151 of the mobile terminal body.
Two or more display units 151 may be implemented according to a configured aspect of the mobile terminal 100. For instance, a plurality of the display units 151 may be arranged on one surface to be spaced apart from or integrated with each other, or may be arranged on different surfaces.
Furthermore, the display unit 151 may be configured with a stereoscopic display unit 152 for displaying a stereoscopic image.
Here, stereoscopic image indicates a 3-dimensional stereoscopic image, and the 3-dimensional stereoscopic image is an image for allowing the user to feel the gradual depth and reality of an object located on the monitor or screen as in a real space. The 3-dimensional stereoscopic image may be implemented by using binocular disparity. Here, binocular disparity denotes a disparity made by the location of two eyes separated from each other, allowing the user to feel the depth and reality of a stereoscopic image when two eyes see different two-dimensional images and then the images are transferred through the retina and merged in the brain as a single image.
A stereoscopic method (glasses method), an auto-stereoscopic method (no-glasses method), a projection method (holographic method), and the like may be applicable to the stereoscopic display unit 152. The stereoscopic method primarily used in a home television receiver and the like may include a Wheatstone stereoscopic method and the like.
The examples of the auto-stereoscopic method may include a parallel barrier method, a lenticular method, an integral imaging method, and the like. The projection method may include a reflective holographic method, a transmissive holographic method, and the like.
In general, a 3-dimensional stereoscopic image may include a left image (image for the left eye) and a right image (image for the right eye). The method of implementing a 3-dimensional stereoscopic image can be divided into a top-down method in which a left image and a right image are disposed at the top and bottom within a frame, a left-to-right (L-to-R) or side by side method in which a left image and a right image are disposed at the left and right within a frame, a checker board method in which the pieces of a left image and a right image are disposed in a tile format, an interlaced method in which a left and a right image are alternately disposed for each column and row unit, and a time sequential or frame by frame method in which a left image and a right image are alternately displayed for each time frame, according to the method of combining a left image and a right image into a 3-dimensional stereoscopic image.
For 3-dimensional thumbnail images, a left image thumbnail and a right image thumbnail may be generated from the left and the right image of the original image frame, and then combined with each other to generate a 3-dimensional stereoscopic image. Typically, thumbnail denotes a reduced image or reduced still video. The left and right thumbnail image generated in this manner are displayed with a left and right distance difference on the screen in a depth corresponding to the disparity of the left and right image, thereby implementing a stereoscopic space feeling.
A left image and a right image required to implement a 3-dimensional stereoscopic image are displayed on the stereoscopic display unit 152 by a stereoscopic processing unit (not shown). The stereoscopic processing unit receives a 3D image to extract a left image and a right image from the 3D image, or receives a 2D image to convert it into a left image and a right image.
On the other hand, when the display unit 151 and a touch sensitive sensor (hereinafter, referred to as a “touch sensor”) have an interlayer structure (hereinafter, referred to as a “touch screen”), the display unit 151 may be used as an input device in addition to an output device. The touch sensor may be implemented as a touch film, a touch sheet, a touch pad, and the like.
The touch sensor may be configured to convert changes of a pressure applied to a specific part of the display unit 151, or a capacitance occurring from a specific part of the display unit 151, into electric input signals. The touch sensor may be configured to sense not only a touched position and a touched area, but also a touch pressure at which a touch object body is touched on the touch sensor. Here, the touch object body may be a finger, a touch pen or stylus pen, a pointer, or the like as an object by which a touch is applied to the touch sensor.
When there is a touch input to the touch sensor, the corresponding signals are transmitted to a touch controller. The touch controller processes the signal(s), and then transmits the corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched.
Referring to
The proximity sensor 141 may include an optical transmission 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 so on. When the touch screen is implemented as a capacitance type, the proximity of an object having conductivity (hereinafter, referred to as a “pointer”) to the touch screen is sensed by changes of an electromagnetic field. In this case, the touch screen (touch sensor) may be categorized into a proximity sensor.
Hereinafter, for the sake of convenience of brief explanation, a behavior that the pointer is positioned to be proximate onto the touch screen without contact will be referred to as a “proximity touch”, whereas a behavior that the pointer substantially comes in contact with the touch screen will be referred to as a “contact touch”. For the position corresponding to the proximity touch of the pointer on the touch screen, such position corresponds to a position where the pointer faces perpendicular to the touch screen upon the proximity touch of the pointer.
The proximity sensor 141 senses a proximity touch, and a proximity touch pattern (e.g., proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch moving status, etc.). Information relating to the sensed proximity touch and the sensed proximity touch patterns may be output onto the touch screen.
When the stereoscopic display unit 152 and a touch sensor are configured with an interlayer structure (hereinafter, referred to as a “stereoscopic touch screen”) or the stereoscopic display unit 152 and a 3D sensor for detecting a touch operation are combined with each other, the stereoscopic display unit 152 may be used as a 3-dimensional input device.
As an example of the 3D sensor, the sensing unit 140 may include a proximity sensor 141, a stereoscopic touch sensing unit 142, a ultrasound sensing unit 143, and a camera sensing unit 144.
The proximity sensor 141 measures a distance between the sensing object (for example, the user's finger or stylus pen) and a detection surface to which a touch is applied using an electromagnetic field or infrared rays without a mechanical contact. The terminal may recognize which portion of a stereoscopic image has been touched by using the measured distance. In particular, when the touch screen is implemented with a capacitance type, it may be configured such that the proximity level of a sensing object is sensed by changes of an electromagnetic field according to the proximity of the sensing object to recognize a 3-dimensional touch using the proximity level.
The stereoscopic touch sensing unit 142 may be configured to sense the strength or duration time of a touch applied to the touch screen. For example, stereoscopic touch sensing unit 142 senses a user applied touch pressure, and if the applied pressure is strong, then the stereoscopic touch sensing unit 142 recognizes it as a touch for an object located farther from the touch screen.
The ultrasound sensing unit 143 may be configured to sense the location of the sensing object using ultrasound.
For example, the ultrasound sensing unit 143 may be configured with an optical sensor and a plurality of ultrasound sensors. The optical sensor may be formed to sense light, and the ultrasound sensor may be formed to sense ultrasound waves. Since light is far faster than ultrasound waves, the time for light to reach the optical sensor is far faster than the time for ultrasound waves to reach the ultrasound sensor. Accordingly, the location of the wave generating source may be calculated using a time difference between the light and ultrasound waves to reach the optical sensor.
The camera sensing unit 144 may include at least one of a camera 121, a photo sensor, and a laser sensor.
For example, the camera 121 and laser sensor may be combined to each other to sense a touch of the sensing object to a 3-dimensional stereoscopic image. Distance information sensed by the laser sensor is added to a two-dimensional image captured by the camera to acquire 3-dimensional information.
For another example, a photo sensor may be deposited on the display element. The photo sensor may be configured to scan the motion of the sensing object in proximity to the touch screen. More specifically, the photo sensor is integrated with photo diodes and transistors in the rows and columns thereof, and a content placed on the photo sensor may be scanned by using an electrical signal that is changed according to the amount of light applied to the photo diode. In other words, the photo sensor performs the coordinate calculation of the sensing object according to the changed amount of light, and the location coordinate of the sensing object may be detected through this.
The audio output module 153 may output audio data received from the wireless communication unit 110 or stored in the memory 160, in a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode, and so on. The audio output module 153 may output audio signals relating to the functions performed in the mobile terminal 100 (e.g., sound alarming a call received or a message received, and so on). The audio output module 153 may include a receiver, a speaker, a buzzer, and so on.
The alarm 154 outputs signals notifying occurrence of events from the mobile terminal 100. The events occurring from the mobile terminal 100 may include call received, message received, key signal input, touch input, and so on. The alarm 154 may output not only video or audio signals, but also other types of signals such as signals notifying occurrence of events in a vibration manner. Since the video or audio signals can be output through the display unit 151 or the audio output unit 153, the display unit 151 and the audio output module 153 may be categorized into part of the alarm 154.
The haptic module 155 generates various tactile effects which a user can feel. A representative example of the tactile effects generated by the haptic module 154 includes vibration. Vibration generated by the haptic module 154 may have a controllable intensity, a controllable pattern, and so on. For instance, different vibration may be output in a synthesized manner or in a sequential manner.
The haptic module 155 may generate various tactile effects, including not only vibration, but also arrangement of pins vertically moving with respect to a skin being touched, air injection force or air suction force through an injection hole or a suction hole, touch by a skin surface, presence or absence of contact with an electrode, effects by stimulus such as an electrostatic force, reproduction of cold or hot feeling using a heat absorbing device or a heat emitting device, and the like.
The haptic module 155 may be configured to transmit tactile effects through a user's direct contact, or a user's muscular sense using a finger or a hand. The haptic module 155 may be implemented in two or more in number according to the configuration of the mobile terminal 100.
The memory 160 may store a program for processing and controlling the controller 180. Alternatively, the memory 160 may temporarily store input/output data (e.g., phonebook, messages, still images, videos, and the like). Also, the memory 160 may store data related to various patterns of vibrations and sounds outputted upon the touch input on the touch screen.
The memory 160 may be implemented using any type of suitable storage medium including a flash memory type, a hard disk type, a multimedia card micro type, a memory card type (e.g., SD or DX memory), Random Access Memory (RAM), Static Random Access Memory (SRAM), Read-Only Memory (ROM), Electrically Erasable Programmable Read-only Memory (EEPROM), Programmable Read-only Memory (PROM), magnetic memory, magnetic disk, optical disk, and the like. Also, the mobile terminal 100 may operate in association with a web storage which performs the storage function of the memory 160 on the Internet.
The interface unit 170 may generally be implemented to interface the mobile terminal with external devices connected to the mobile terminal 100. The interface unit 170 may allow a data reception from an external device, a power delivery to each component in the mobile terminal 100, or a data transmission from the mobile terminal 100 to an external device. The interface unit 170 may include, for example, wired/wireless headset ports, external charger ports, wired/wireless data ports, memory card ports, ports for coupling devices having an identification module, audio Input/Output (I/O) ports, video I/O ports, earphone ports, and the like.
On the other hand, the identification module may be configured as a chip for storing various information required to authenticate an authority to use the mobile terminal 100, which may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), and the like. Also, the device having the identification module (hereinafter, referred to as “identification device”) may be implemented in a type of smart card. Hence, the identification device can be coupled to the mobile terminal 100 via a port.
Furthermore, the interface unit 170 may serve as a path for power to be supplied from an external cradle to the mobile terminal 100 when the mobile terminal 100 is connected to the external cradle or as a path for transferring various command signals inputted from the cradle by a user to the mobile terminal 100. Such various command signals or power inputted from the cradle may operate as signals for recognizing that the mobile terminal 100 has accurately been mounted to the cradle.
The controller 180 typically controls the overall operations of the mobile terminal 100. For example, the controller 180 performs the control and processing associated with telephony calls, data communications, video calls, and the like. The controller 180 may include a multimedia module 181 which provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180 or as a separate component.
Furthermore, the controller 180 can perform a pattern recognition processing so as to recognize writing or drawing input carried out on the touch screen as text or image.
Furthermore, the controller 180 may implement a lock state for limiting the user's control command input to applications when the state of the mobile terminal satisfies a preset condition. Furthermore, the controller 180 may control a lock screen displayed in the lock state based on a touch input sensed through the display unit 151 in the lock state.
The power supply unit 190 receives external and internal power to provide power required for various components under the control of the controller 180.
Various embodiments described herein may be implemented in a computer or similar device readable medium using software, hardware, or any combination thereof.
For hardware implementation, it may be implemented by 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 electrical units designed to perform the functions described herein. In some cases, such embodiments may be implemented in the controller 180 itself.
For software implementation, the embodiments such as procedures or functions described in the present disclosure may be implemented with separate software modules. Each of the software modules may perform at least one function or operation described in the present disclosure.
Software codes can be implemented by a software application written in any suitable programming language. The software codes may be stored in the memory 160 and executed by the controller 180.
Next, a communication system that can be implemented through the mobile terminal 100 according to the present disclosure will be described.
First, referring to
Hereinafter, for the sake of convenience of explanation, the description disclosed herein will be limited to CDMA. However, it is apparent that the present invention may be also applicable to all communication systems including a CDMA wireless communication system.
As illustrated in
Each of the plurality of BSs 270 may include at least one sector, each sector having an omni-directional antenna or an antenna indicating a particular radial direction from the base station 270. Alternatively, each sector may include two or more antennas with various forms. Each of the BSs 270 may be configured to support a plurality of frequency assignments, each frequency assignment having a particular spectrum (for example, 1.25 MHz, 5 MHz, etc.).
The intersection of a sector and frequency assignment may be referred to as a CDMA channel. The BSs 270 may also be referred to as Base Station Transceiver Subsystems (BTSs). In this case, the term “base station” may collectively refer to a BSC 275, and at least one BS 270. The base stations may also indicate “cell sites”. Alternatively, individual sectors for a specific BS 270 may also be referred to as a plurality of cell sites.
As illustrated in
In addition,
During the operation of a wireless communication system, the BS 270 may receive reverse-link signals from various mobile terminals 100. At this time, the mobile terminals 100 may perform calls, message transmissions and receptions, and other communication operations. Each reverse-link signal received by a specific base station 270 may be processed within that specific base station 270. The processed resultant data may be transmitted to an associated BSC 275. The BSC 275 may provide call resource allocation and mobility management functions including the systemization of soft handoffs between the base stations 270. Furthermore, the BSCs 275 may also transmit the received data to the MSC 280, which provides additional transmission services for interfacing with the PSTN 290. Furthermore, similarly, the PSTN 290 may interface with the MSC 280, and the MSC 280 may interface with the BSCs 275. The BSCs 275 may also control the BSs 270 to transmit forward-link signals to the mobile terminals 100.
Next, a method of acquiring the location information of a mobile terminal using a WiFi (Wireless Fidelity) positioning system (WPS) will be described with reference to
The WiFi positioning system (WPS) 300 refers to a location determination technology based on a wireless local area network (WLAN) using WiFi as a technology for tracking the location of the mobile terminal 100 using a WiFi module provided in the mobile terminal 100 and a wireless access point 320 for transmitting and receiving to and from the WiFi module.

On the other hand, the mobile terminal 100 may display visual information (or screen information, hereinafter “screen information”) on the display unit 151. The screen information may include at least one of text data and image data. Furthermore, the mobile terminal 100 may be coupled to an external device (for example, earphone) through the interface unit 170. However, when the user wants to execute an application (for example, music play application) associated with an external device coupled to the interface unit 170 in a state that he or she views the screen information, several steps of processes may be carried out to execute an additional application, thereby causing inconvenience that several seconds are consumed.
Accordingly, hereinafter, a mobile terminal 100 capable of enhancing the user's convenience when performing a multitasking function and a control method thereof will be described with reference to the accompanying drawings.
Referring to
The interface unit 170 may be formed to be detachable with respect to an external device. The interface unit 170 may include at least one port configured to be detachable with respect to an external device. For example, the interface unit 170 may include a port configured to be detachable with respect to an earphone connector, a port configured to be detachable with respect to a USB connector, a port configured to withdraw a DMB antenna, and the like. The earphone connector and USB connector may transfer a voltage generated from the earphone and external electronic device, respectively, to the body of the mobile terminal 100 through the port.
The sensing unit 140 may sense whether the external device is coupled to or separated from a port. Furthermore, the sensing unit 140 may sense that the external device is withdrawn from a port. The sensing unit 140 may transfer a sensing result to the controller 180.
Next, the process (S120) of displaying graphic data corresponding to the sensing result on the display unit 151 is carried out.
Specifically, when the external device is coupled to or separated from any one of the at least one port, the controller 180 may display graphic data indicating that the external device is coupled thereto or separated therefrom in a region adjacent to the port on the display unit 151.
The controller 180 may display graphic data to be overlapped with screen information previously displayed on the display unit 151. Meanwhile, the controller 180 may generate a new region while allowing at least part of the screen information previously displayed on the display unit 151 to disappear, and display the graphic data in the generated region.
For example, when an earphone connector is coupled to an earphone port, the controller 180 may display graphic data (for example, an image having the shape of an earphone connector) indicating that an earphone is connected thereto in a region adjacent to the earphone port. Accordingly, an emotional effect indicating that an earphone connector is coupled to an earphone port may be provided to the user.
Then, the process (S130) of displaying at least one execution menu on the display unit 151 to execute a function associated with the sensing result is carried out.
When a predetermined period of time has passed in a state that graphic data is displayed on the display unit 151, the controller 180 may allow the graphic data to disappear, and display at least one execution menu in a region from which the graphic data disappears. Here, the execution menu may include an icon corresponding to an application associated with the sensing result.
The controller 180 may recommend at least one application based on at least one of the type of the external device and whether or not it is coupled to the external device. The controller 180 may display an icon corresponding to the recommended application as an execution menu.
Then, though not shown in the drawing, when any one icon is selected from the execution menu, the controller 180 may execute an application corresponding to the selected icon, and display the execution screen of the application on the display unit 151.
On the other hand, though not shown in the drawing, the number of applications recommended based on at least one of the type of the external device and whether or not it is coupled to the external device is one, the controller 180 may immediately execute the recommended application without displaying the execution menu 252 on the display unit 151.
Furthermore, though not shown in the drawing, the foregoing embodiment may be applicable even when the external device is separated from the port. Meanwhile, a graphic image indicating that the external device is separated therefrom may be displayed on the display unit 151 when the external device is separated therefrom in a state that the execution menu is displayed on the display unit 151, and there may be no change in screen information displayed on the display unit 151 when the external device is separated therefrom in a state that the execution menu is not displayed on the display unit 151.
As described above, according to the present disclosure, when the mobile terminal 100 is coupled to an external device (for example, earphone) through the interface unit 170, graphic data indicating that it is coupled to the external device may be displayed on the display unit 151. Accordingly, emotional pleasure may be provided to the user.
Furthermore, according to the present disclosure, an execution menu may be displayed on the display unit 151 to execute a function associated with the external device. Accordingly, an application associated with the external device may be immediately executed based on the user's selection. In other words, an entry path for executing a function associated with the external device may be provided with a unified control action in a state that any screen information is displayed on the display unit 151. Accordingly, the user may use a function associated with the external device even without performing a complicated manipulation during the multitasking process. As a result, it may be possible to enhance the user's convenience.
