Hereinafter, the components will be described in order.

The wireless communication unit 110 may include one or more components for wireless communication between the mobile terminal 100 and the wireless communication system or wireless communication between the mobile terminal 100 and a network on which the mobile terminal 100 is located. For example, the wireless communication unit 110 may transmit at least one of the broadcast reception module 111, the mobile communication module 112, the wireless Internet module 113, the short distance communication module 114, and the location information module 115 .

The broadcast receiving module 111 receives broadcast signals and / or broadcast-related information from an external broadcast management server through a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast management server may refer to a server for generating and transmitting broadcast signals and / or broadcast related information, or a server for receiving broadcast signals and / or broadcast related information generated by the broadcast management server and transmitting the generated broadcast signals and / or broadcast related information. The broadcast-related information may refer to a broadcast channel, a broadcast program, or information related to a broadcast service provider. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and a broadcast signal in which a data broadcast signal is combined with a TV broadcast signal or a radio broadcast signal.

Meanwhile, the broadcast related information may be provided through a mobile communication network, and in this case, it may be received by the mobile communication module 112.

The broadcast-related information may exist in various forms. For example, an EPG (Electronic Program Guide) of DMB (Digital Multimedia Broadcasting) or an ESG (Electronic Service Guide) of Digital Video Broadcast-Handheld (DVB-H).

The broadcast receiving module 111 receives broadcasting signals using various broadcasting systems. In particular, the broadcasting receiving module 111 may be a Digital Multimedia Broadcasting-Terrestrial (DMB-T), a Digital Multimedia Broadcasting-Satellite (DMB-S) Only Digital Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T), and the like. Of course, the broadcast receiving module 111 is configured to be suitable for all broadcasting systems that provide broadcasting signals as well as the digital broadcasting system described above. The broadcast signal and / or broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

In addition, the mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. Here, the wireless signal may include various types of data depending on a voice call signal, a video call signal, or a text / multimedia message transmission / reception.

The wireless Internet module 113 is for wireless Internet access, and may be embedded in a mobile terminal or externally. WLAN (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) and the like can be used as wireless Internet technologies.

The short-range communication module 114 is a module for short-range communication. Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, and the like can be used as the short distance communication technology.

The location information module 115 is a module for confirming or obtaining the location of the mobile terminal. One example is the GPS (Global Position System) module. The GPS module receives position information from a plurality of satellites. Here, the location information may include coordinate information indicated by latitude and longitude. For example, the GPS module can accurately calculate the current location according to the triangulation method by measuring the precise time and distance from three or more satellites and measuring three different distances. A method of obtaining distance and time information from three satellites and correcting the error by one satellite may be used. In particular, the GPS module can acquire latitude, longitude and altitude as well as three-dimensional velocity information and accurate time from the position information received from the satellite.

The A / V (Audio / Video) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes an image frame of a still image or a moving image obtained by the image sensor in a video communication mode or a photographing mode. Then, the processed image frame can be displayed on the display unit 151. [

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. The camera 121 may include two or more cameras according to the configuration of the terminal.

The microphone 122 receives an external sound signal by a microphone in a communication mode, a recording mode, a voice recognition mode, and the like and processes it as electrical voice data. The processed voice data may be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. The microphone 122 may have various noise elimination algorithms for eliminating noise generated in receiving an external sound signal.

The user input unit 130 generates input data for a user to control operation of the terminal. The user input unit 130 may include a key pad, a dome switch, a touch pad (static / static), a jog wheel, a jog switch, and the like. Particularly, when the touch pad has a mutual layer structure with the display unit 151 described later, it can be called a touch screen.

The sensing unit 140 senses the current state of the mobile terminal 100 such as the open / close state of the mobile terminal 100, the position of the mobile terminal 100, the presence of the user, the orientation of the mobile terminal, And generates a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141. This will be discussed later in connection with touch screens.

The interface unit 170 serves as an interface with all the external devices connected to the mobile terminal 100. For example, 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 an identification module, an audio I / O port, A video input / output (I / O) port, an earphone port, and the like may be included in the interface unit 170.

Here, the identification module is a chip for storing various information for authenticating the usage right of the mobile terminal 100, and includes a user identification module (UIM), a subscriber identity module (SIM) , A Universal Subscriber Identity Module (" USIM "), and the like. In addition, an apparatus having an identification module (hereinafter referred to as 'identification device') can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port.

The interface unit 170 receives data from an external device or receives power from the external device, transfers the data to each component in the mobile terminal 100, or transmits data of the mobile terminal 100 to an external device.

The interface unit 170 may be a path through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle, Various command signals may be transmitted to the mobile terminal. The various command signals or the power source input from the cradle may be operated as a signal for recognizing that the mobile terminal is correctly mounted on the cradle.

The output unit 150 is for outputting an audio signal, a video signal, or an alarm signal. The output unit 150 may include a display unit 151, an audio output module 152, and an alarm unit 153.

The display unit 151 displays and outputs information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or GUI (Graphic User Interface) related to the call is displayed. If the mobile terminal 100 is in the video communication mode or the photographing mode, the captured image and / or the received image or UI and GUI are displayed.

Meanwhile, as described above, when the display unit 13 and the touch pad have a mutual layer structure to form a touch screen, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display 3D display). Some of these displays can be configured to be transparent so that they can be viewed from outside. This may be referred to as a transparent display. A typical example of the transparent display is a transparent organic light emitting diode (TOLED) or the like. There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, the mobile terminal 100 may include an external display unit (not shown) and an internal display unit (not shown) at the same time.

The touch screen may be configured to detect not only the touch input position and area but also the touch input pressure.

Meanwhile, the proximity sensor 141 may be disposed inside or near the touch screen. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. Therefore, the proximity sensor 141 has a considerably long life span and its utilization is also significantly higher than that of the contact-type sensor.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

Among them, the operation principle of the high-frequency oscillation type proximity sensor will be described. In the oscillation circuit, when the high frequency of the stationary wave is oscillated, the oscillation amplitude of the oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface, These changes are converted into electrical signals to detect the presence or absence of the sensing object. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

The proximity sensor 141 may be configured so as to detect the proximity of the pointer with the change of the electric field along the proximity of the pointer if the touch screen is electrostatic.

Accordingly, when the pointer is not actually touched on the touch screen but is located close to the touch screen, the position of the pointer and the distance between the pointer and the touch screen can be detected. Hereinafter, for the sake of convenience of description, the act of allowing the pointer to be located on the touch screen to recognize that the pointer is positioned on the touch screen is referred to as "proximity touch ", and a pointer The actual touching action will be referred to as "contact touch. &Quot; In addition, a position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects proximity touches and proximity touch patterns (e.g., proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, and the like) , And may output information corresponding to the detected proximity touch operation and the proximity touch pattern on the touch screen.

The sound output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, and a broadcast reception mode. The sound output module 152 outputs an acoustic signal related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of the event include a call signal reception, a message reception, a key signal input, a touch input, and the like. The alarm unit 153 outputs a signal for informing occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, the alarm unit 153 can output a vibration to notify it. Alternatively, when the key signal is inputted, the vibration can be outputted as the feedback to the key signal input. The user can recognize the occurrence of an event through the vibration output as described above. Of course, a signal for notifying the occurrence of an event may also be output through the display unit 151 or the sound output module 152.

The memory 160 may store a program for processing and control of the controller 180 and may have a function for temporarily storing input / output data (e.g., a phone book, a message, a still image, . ≪ / RTI > In addition, the memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory) SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory) A storage medium of at least one type of a disk, an optical disk, and the like. In addition, the mobile terminal 100 may operate a web storage for storing the memory 150 on the Internet.

The controller 180 typically controls the overall operation of the mobile terminal. For example, voice communication, data communication, video communication, and the like. In addition, the control unit 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented in the control unit 180 or may be implemented separately from the control unit 180. [

The controller 180 may perform a pattern recognition process for recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.

[ Similarly, the PSTN 290 connects to the MSC 280, the MSC 280 connects to the BSCs 275, and the BSCs 275 communicate with the BSs 270 ).

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. An aspect of the present invention is to implement a mobile terminal that adds directionality to vibration.

A first embodiment of the present invention relates to a method of applying vibration to motion picture reproduction.

FIG. 5 is a flowchart showing the vibration control according to the first embodiment of the present invention, and FIG. 6 is an illustration of the vibration control UI according to the first embodiment.

The present invention determines whether to activate the vibration mode (set or not) prior to moving picture playback as shown in FIG. 6A). And, when activating the vibration mode, set the mode type of vibration. (S10 & S20) For example, any one of various modes such as an action mode, a sports mode, a drama mode, a concert mode, a game mode, and an FX mode is selected.

Thereafter, when a codec (CODEC) is executed for reproducing a moving image and a specific moving image is selected according to the input of the user, the controller 180 first checks the compression type of the selected moving image (S30 & S40) The control unit 180 extracts a motion vector from the specific video data of the moving picture, for example, from the B-frame (or P-frame) of the moving picture (S50) , And controls the vibration direction and intensity of the vibration elements according to the extracted motion vector. (S60) It is assumed that the vibration part according to the present embodiment includes four vibration elements.

MPEG-2 is an extension of MPEG-1 and is suitable for high-definition applications and TV broadcasting applications, unlike MPEG-1, which is suitable for playback on CD-ROMs. In the case of satellite broadcasts, MPEG-2 can encode five or more digital channels at the same bandwidth that one analog channel currently uses, without any loss of image quality.

6 (b) is a diagram showing vibration control of moving images using audio data.

As shown in FIG. 6B, the terminal according to the present invention can control the vibration of the terminal using PAM () data. The controller 180 detects palm (PAM) data of the stereo audio from the moving picture being reproduced by the codec and determines the direction and intensity of the vibration according to the detected palm (PAM) data.

When the user sets the stereo vibration, the controller 180 drives at least one or more vibration elements (e.g., two or more) to control the vibration of the elements according to the detected palm (PAM) data do. When the user sets the surround vibration, the controller 180 drives at least two or more vibration elements (e.g., three or more) to detect the vibration of the elements according to the detected palm data .

Vibration control using audio data and vibration control using video data may be selectively applied to the terminal or may be applied redundantly.

On the other hand, unlike MPEG-1, which is used in video or CD, and MPEG-2, which is used in broadcast or HDTV, MPEG-4 has started to be standardized with the aim of expanding its use to a low bit rate situation. As an encoding technology, H.263, which was standardized first, was constructed by adding several tools based on it. The difference from H.263 is that B frame is adopted in inter-frame prediction and AC / DC prediction of DCT coefficient is introduced. In the case of the MPEG-4 system, various objects (Objects) constituting one scene (or image) are separated and compressed, and the compressed information is transmitted.

FIG. 7 is a view showing a vibration setting screen of a moving picture according to the MPEG-4 system.

When a moving picture according to the MPEG-4 system (or H.264 system) is reproduced, the present invention can select an object to which vibration is applied, as shown in FIG. (S70)

If it is determined in step S40 that the selected moving picture conforms to the MPEG-4 scheme (or H.264 scheme), the user can select one of the objects appearing in the moving picture, A UI screen such as a bar is displayed.

When a specific object is selected on the UI screen, the controller 180 controls the vibration direction and the intensity of the vibration elements according to the motion of the selected object (e.g., a motion vector). (S80)

FIG. 8 is a diagram showing an example of a vibration control UI according to a second embodiment of the present invention, in which vibration control according to the present invention is applied to a game.

When the vibration control according to the present invention is applied to a game, the controller 180 controls the vibration elements similarly to the case of the MPEG-4 method (or the H.264 method). As shown in FIG. 8, the emerging characters of the game are listed, and the user sets a character to apply the vibration. And the mode type of vibration intensity and vibration (for example, action mode, sports mode, drama mode, concert mode, battle scene mode, and the like) are set.

In the UI of FIG. 8, when a character to be applied vibration is set, the controller 180 controls the vibration direction and the intensity of the vibration elements according to the motion of the selected character (e.g., motion vector).

FIG. 9 is a flowchart showing vibration control according to the third embodiment of the present invention, and FIG. 10 is an illustration of vibration control according to the third embodiment.

As shown in FIG. 9, when a predetermined image viewer is executed, the control unit 180 first sets a threshold value for image movement (hereinafter, referred to as a 'critical point 610'). (S210) At this time, setting the critical point 610 means not to give a specific value, but to allow the critical point 610 to act (activate) the image movement. For convenience of explanation, FIG. 10 shows a critical point on the screen.

10, the user views the images (image # 1, image # 2, image # 3, image # 4, ..., image #n) of the viewer screen 600 And moves to the side point 620 for image appreciation in the next step. The user moves the image (e.g., image # 2) through a predetermined touch operation (e.g., touch and drag or flicking).

When the image movement is started by the user's touch operation (e.g., touch and drag or flicking), the controller 180 detects the movement of the image and outputs the vibration. (S220)

The critical point 610 is a reference point for moving the image.

The user moves back to the original position or moves to the target point 620 depending on whether the moving image exceeds the critical point 610 by the touch operation of the user. That is, when the touch operation is performed while the user does not completely move the image, the image (image # 2) moves to the target point 620 when the collected point exceeds the critical point 610 . However, if the threshold point 610 is not exceeded, the image # 2 does not move to the target point 620. Image # 2 returns to the original position again.

The present invention can apply the acceleration motion mechanism (acceleration mechanism) to the movement of the image returning to the original position and the movement of the image moving to the target point 620 after the user has performed the touch operation . The acceleration motion technique is an animation technique applying a physical motion law of acceleration and reverse acceleration so that movement of a selected object on a UI has a feeling of realism when a GUI (Graphic User Interface) is implemented.

In step S220, the controller 180 outputs vibration from the moment the movement of the image # 2 is sensed, and gradually outputs the intensity of the vibration gradually toward the critical point 610 (S230 & S240) The strongest intensity vibration is output at the moment of passing the critical point 610, and the intensity gradually weakens from the moment of passing the critical point 610. By implementing the intensity of the vibration to be proportional to the distance of the image and the critical point 610, the present invention can be applied to a case where the image moves in the opposite direction of the critical point 610 at the position where the image was originally located, (S230 & S250)

Since the intensity of the vibration is gradually and weakly output from the moment of passing the critical point 610, the user according to the present invention can grasp the critical point 610 only by the intensity of the vibration transmitted through the touch, Can be collected. When the user takes a touch at a point beyond the critical point 610, the image automatically moves to the target point 620. [

Fig. 11 is an example of vibration control using two vibration elements as another embodiment of Fig. 10; Fig.

The control unit 180 of the present embodiment drives the vibration elements 650 and 660 at two points as shown in FIG. 11 instead of setting the critical point 610 when a predetermined image viewer (Image Viewer) is executed .

10, the controller 180 drives the vibration elements 650 and 660 when the user moves the image # 2 to the side point 620 for the next image appreciation.

The control unit 180 detects the movement of the image by the touch operation (e.g., touch and drag or flicking) of the user and detects the movement of the first vibration element 650 and the second vibration element The vibration of the vibration element 660 is driven at different intensities. The intensity of the first oscillation element 650 is controlled to be strong and the intensity of the second oscillation element 660 is controlled to be weak so that the user who has moved the image will gradually feel a weaker oscillation toward the target point 620.

FIG. 12 is a flowchart showing vibration control according to a fourth embodiment of the present invention, and FIGS. 13 to 15 are illustrations of vibration control according to the fourth embodiment. The mobile terminal according to the present embodiment constitutes a vibrating element as shown in FIG.

When a predetermined image viewer (e.g., a camera album) is executed in the terminal (S310), the controller 180 first selects a specific image according to the user's input (S320) Display the image on the screen and wait for user input.

Thereafter, when an input instructing enlargement (or zoom-in) of the image is received from the user, the controller 180 drives the third oscillator 670 as shown in FIG. (S330 & S340) At this time, the controller 180 controls the third oscillating element 670 so that the oscillation is radially transmitted from the center of the screen to the outside.

15, the controller 180 drives the first oscillation element 650 and the second oscillation element 660 (S330 & S350). If the input is instructed by the user, At this time, the vibrations generated by the first and second vibration elements 650 and 660 are radially transmitted from the outer periphery to the center of the screen.

The controller 180 controls the drive of the corresponding vibration element so that the user can continue to feel the vibration while the user is inputting an image enlargement (or reduction) button (e.g., software key, hardware button, etc.) .

16 is an exemplary view showing enlargement and reduction of an image by multi-touch input.

This embodiment can deliver a more realistic feel to the user when enlarging (or reducing) the image with multi-touch input. While enlarging or reducing the image with multi-touch, the user can sense that the intensity of the vibration of the screen changes.

FIG. 17 shows a method of changing the intensity of vibration according to the magnification (or reduction) of an image as another embodiment of FIG.

Each time the image enlargement (or zoom-in) button is input, the controller 180 increases the intensity of the vibration in stages. Further, each time the image reduction (or zoom-out) button is input, the controller 180 decreases the intensity of the vibration in stages.

The vibration control according to each embodiment of the present invention can be implemented as a computer-readable code on a medium on which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of the computer-readable medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . The computer may include a controller 180 of the mobile terminal.

As described above, the mobile terminal according to the present invention adds directionality to the vibration by using at least one vibration element, so that the user can transmit the tension or mobility of the moving picture (or game) screen as it is.

Further, the present invention can provide users with synoptic effects by visual, auditory, and tactile sense by stimulating the tactile sense by the directional vibration.
