FIG. 1 shows the mobile terminal 100 having various components, but it is understood that implementing all of the illustrated components is not a requirement. Greater or fewer components may alternatively be implemented.
In the following description, the above elements of the mobile terminal 100 are explained in sequence.
First of all, the wireless communication unit 110 typically includes one or more components which permits wireless communication between the mobile terminal 100 and a wireless communication system or network within which the mobile terminal 100 is located. For instance, the wireless communication unit 110 can include a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, a position-location module 115 and the like.
The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast managing server via a broadcast channel.
The broadcast channel may include a satellite channel and a terrestrial channel.
The broadcast managing server generally refers to a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which is provided with a previously generated broadcast signal and/or broadcast associated information and then transmits the provided signal or information to a terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. If desired, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal.
The broadcast associated information includes information associated with a broadcast channel, a broadcast program, a broadcast service provider, etc. And, the broadcast associated information can be provided via a mobile communication network. In this case, the broadcast associated information can be received by the mobile communication module 112.
The broadcast associated information can be implemented in various forms. For instance, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H).
The broadcast receiving module 111 may be configured to receive broadcast signals transmitted from various types of broadcast systems. By nonlimiting example, such broadcasting systems include digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), the data broadcasting system known as media forward link only (MediaFLO®) and integrated services digital broadcast-terrestrial (ISDB-T). Optionally, the broadcast receiving module 111 can be configured suitable for other broadcasting systems as well as the above-explained digital broadcasting systems.
The broadcast signal and/or broadcast associated information received by the broadcast receiving module 111 may be stored in a suitable device, such as a memory 160.
The mobile communication module 112 transmits/receives wireless signals to/from one or more network entities (e.g., base station, external terminal, server, etc.). Such wireless signals may represent audio, video, and data according to text/multimedia message transceiving, among others.
The wireless internet module 113 supports Internet access for the mobile terminal 100. This module may be internally or externally coupled to the mobile terminal 100. In this case, the wireless Internet technology can include WLAN (Wireless LAN) (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), etc.
The short-range communication module 114 facilitates relatively short-range communications. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few.
The position-location module 115 identifies or otherwise obtains the location of the mobile terminal 100. If desired, this module may be implemented with a global positioning system (GPS) module.
Referring to FIG. 1, the audio/video (A/V) input unit 120 is configured to provide audio or video signal input to the mobile terminal 100. As shown, the A/V input unit 120 includes a camera 121 and a microphone 122. The camera 121 receives and processes image frames of still pictures or video, which are obtained by an image sensor in a video call mode or a photographing mode. And, the processed image frames can be displayed on the display unit 151.
The image frames processed by the camera 121 can be stored in the memory 160 or can be externally transmitted via the wireless communication unit 110. Optionally, at least two cameras 121 can be provided to the mobile terminal 100 according to environment of usage.
The microphone 122 receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition. This audio signal is processed and converted into electric audio data. The processed audio data is transformed into a format transmittable to a mobile communication base station via the mobile communication module 112 in case of a call mode. The microphone 122 typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.
The user input unit 130 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch, etc.
The sensing unit 140 provides sensing signals for controlling operations of the mobile terminal 100 using status measurements of various aspects of the mobile terminal. For instance, the sensing unit 140 may detect an open/close status of the mobile terminal 100, relative positioning of components (e.g., a display and keypad) of the mobile terminal 100, a change of position of the mobile terminal 100 or a component of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, orientation or acceleration/deceleration of the mobile terminal 100. As an example, consider the mobile terminal 100 being configured as a slide-type mobile terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device. And, the sensing unit 140 can include a proximity sensor 141.
The output unit 150 generates outputs relevant to the senses of sight, hearing, touch and the like. And, the output unit 150 includes the display unit 151, an audio output module 152, an alarm unit 153, a haptic module 154, a projector module 155 and the like.
The display unit 151 is typically implemented to visually display (output) information associated with the mobile terminal 100. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface (UI) or graphical user interface (GUI) which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display unit 151 may additionally or alternatively display images which are associated with these modes, the UI or the GUI.
The display module 151 may be implemented using known display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal 100 may include one or more of such displays.
Some of the above displays can be implemented in a transparent or optical transmittive type, which can be named a transparent display. As a representative example for the transparent display, there is TOLED (transparent OLED) or the like. A rear configuration of the display unit 151 can be implemented in the optical transmittive type as well. In this configuration, a user is able to see an object in rear of a terminal body via the area occupied by the display unit 151 of the terminal body.
At least two display units 151 can be provided to the mobile terminal 100 in accordance with the implemented configuration of the mobile terminal 100. For instance, a plurality of display units can be arranged on a single face of the mobile terminal 100 in a manner of being spaced apart from each other or being built in one body. Alternatively, a plurality of display units can be arranged on different faces of the mobile terminal 100.
In case that the display unit 151 and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) configures a mutual layer structure (hereinafter called ‘touchscreen’), it is able to use the display unit 151 as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, a touchpad or the like.
The touch sensor can be configured to convert a pressure applied to a specific portion of the display unit 151 or a variation of a capacitance generated from a specific portion of the display unit 151 to an electric input signal. Moreover, it is able to configure the touch sensor to detect a pressure of a touch as well as a touched position or size.
If a touch input is made to the touch sensor, signal(s) corresponding to the touch is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 180. Therefore, the controller 180 is able to know whether a prescribed portion of the display unit 151 is touched.
Referring to FIG. 1, a proximity sensor (not shown in the drawing) can be provided to an internal area of the mobile terminal 100 enclosed by the touchscreen or around the touchscreen. The proximity sensor is the sensor that detects a presence or non-presence of an object approaching a prescribed detecting surface or an object existing around the proximity sensor using an electromagnetic field strength or infrared ray without mechanical contact. Hence, the proximity sensor has durability longer than that of a contact type sensor and also has utility wider than that of the contact type sensor.
The proximity sensor can include one of a transmittive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, an infrared proximity sensor and the like. In case that the touchscreen includes the electrostatic capacity proximity sensor, it is configured to detect the proximity of a pointer using a variation of electric field according to the proximity of the pointer. In this case, the touchscreen (touch sensor) can be classified as the proximity sensor.
In the following description, for clarity, an action that a pointer approaches without contacting with the touchscreen to be recognized as located on the touchscreen is named ‘proximity touch’. And, an action that a pointer actually touches the touchscreen is named ‘contact touch’. The meaning of the position on the touchscreen proximity-touched by the pointer means the position of the pointer which vertically opposes the touchscreen when the pointer performs the proximity touch.
The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state, etc.). And, information corresponding to the detected proximity touch action and the detected proximity touch pattern can be outputted to the touchscreen.
The audio output module 152 functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode and the like to output audio data which is received from the wireless communication unit 110 or is stored in the memory 160. During operation, the audio output module 152 outputs audio relating to a particular function (e.g., call received, message received, etc.). The audio output module 152 is often implemented using one or more speakers, buzzers, other audio producing devices, and combinations thereof.
The alarm unit 153 is output a signal for announcing the occurrence of a particular event associated with the mobile terminal 100. Typical events include a call received event, a message received event and a touch input received event. The alarm unit 153 is able to output a signal for announcing the event occurrence by way of vibration as well as video or audio signal. The video or audio signal can be outputted via the display unit 151 or the audio output unit 152. Hence, the display unit 151 or the audio output module 152 can be regarded as a part of the alarm unit 153.
The haptic module 154 generates various tactile effects that can be sensed by a user. Vibration is a representative one of the tactile effects generated by the haptic module 154. Strength and pattern of the vibration generated by the haptic module 154 are controllable. For instance, different vibrations can be outputted in a manner of being synthesized together or can be outputted in sequence.
The haptic module 154 is able to generate various tactile effects as well as the vibration. For instance, the haptic module 154 generates the effect attributed to the arrangement of pins vertically moving against a contact skin surface, the effect attributed to the injection/suction power of air though an injection/suction hole, the effect attributed to the skim over a skin surface, the effect attributed to the contact with electrode, the effect attributed to the electrostatic force, the effect attributed to the representation of hold/cold sense using an endothermic or exothermic device and the like.
The haptic module 154 can be implemented to enable a user to sense the tactile effect through a muscle sense of finger, arm or the like as well as to transfer the tactile effect through a direct contact. Optionally, at least two haptic modules 154 can be provided to the mobile terminal 100 in accordance with the corresponding configuration type of the mobile terminal 100.
The projector module 155 is the element for performing an image projector function using the mobile terminal 100. And, the projector module 155 is able to display an image, which is identical to or partially different at least from the image displayed on the display unit 151, on an external screen or wall according to a control signal of the controller 180.
In particular, the projector module 155 can include a light source (not shown in the drawing) generating light (e.g., laser) for projecting an image externally, an image producing means (not shown in the drawing) for producing an image to output externally using the light generated from the light source, and a lens (not shown in the drawing) for enlarging to output the image externally in a predetermined focus distance. And, the projector module 155 can further include a device (not shown in the drawing) for adjusting an image projected direction by mechanically moving the lens or the whole module.
The projector module 155 can be classified into a CRT (cathode ray tube) module, an LCD (liquid crystal display) module, a DLP (digital light processing) module or the like according to a device type of a display means. In particular, the DLP module is operated by the mechanism of enabling the light generated from the light source to reflect on a DMD (digital micro-mirror device) chip and can be advantageous for the downsizing of the projector module 151.
Preferably, the projector module 155 can be provided in a length direction of a lateral, front or backside direction of the mobile terminal 100. And, it is understood that the projector module 155 can be provided to any portion of the mobile terminal 100 according to the necessity thereof.
The memory unit 160 is generally used to store various types of data to support the processing, control, and storage requirements of the mobile terminal 100. Examples of such data include program instructions for applications operating on the mobile terminal 100, contact data, phonebook data, messages, audio, still pictures, moving pictures, etc. And, a recent use history or a cumulative use frequency of each data (e.g., use frequency for each phonebook, each message or each multimedia) can be stored in the memory unit 160. Moreover, data for various patterns of vibration and/or sound outputted in case of a touch input to the touchscreen can be stored in the memory unit 160.
The memory 160 may be implemented using any type or combination of suitable volatile and non-volatile memory or storage devices including hard disk, random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, multimedia card micro type memory, card-type memory (e.g., SD memory, XD memory, etc.), or other similar memory or data storage device. And, the mobile terminal 100 is able to operate in association with a web storage for performing a storage function of the memory 160 on Internet.
The interface unit 170 is often implemented to couple the mobile terminal 100 with external devices. The interface unit 170 receives data from the external devices or is supplied with the power and then transfers the data or power to the respective elements of the mobile terminal 100 or enables data within the mobile terminal 100 to be transferred to the external devices. The interface unit 170 may be configured using a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for coupling to a device having an identity module, audio input/output ports, video input/output ports, an earphone port and/or the like.
The identity module is the chip for storing various kinds of information for authenticating a use authority of the mobile terminal 100 and can include User Identify Module (UIM), Subscriber Identify Module (SIM), Universal Subscriber Identity Module (USIM) and/or the like. A device having the identity module (hereinafter called ‘identity device’) can be manufactured as a smart card. Therefore, the identity device is connectable to the mobile terminal 100 via the corresponding port.
When the mobile terminal 110 is connected to an external cradle, the interface unit 170 becomes a passage for supplying the mobile terminal 100 with a power from the cradle or a passage for delivering various command signals inputted from the cradle by a user to the mobile terminal 100. Each of the various command signals inputted from the cradle or the power can operate as a signal enabling the mobile terminal 100 to recognize that it is correctly loaded in 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 voice calls, data communications, video calls, etc. The controller 180 may include a multimedia module 181 that provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180, or implemented as a separate component.
Moreover, the controller 180 is able to perform a pattern recognizing process for recognizing a writing input and a picture drawing input carried out on the touchscreen as characters or images, respectively.

FIG. 2A is a front perspective diagram of a mobile terminal according to one embodiment of the present invention.
The mobile terminal 100 shown in the drawing has a bar type terminal body. Yet, the mobile terminal 100 may be implemented in a variety of different configurations. Examples of such configurations include folder-type, slide-type, rotational-type, swing-type and combinations thereof. For clarity, further disclosure will primarily relate to a bar-type mobile terminal 100. However such teachings apply equally to other types of mobile terminals.
Referring to FIG. 2A, the mobile terminal 100 includes a case (casing, housing, cover, etc.) configuring an exterior thereof. In the present embodiment, the case can be divided into a front case 101 and a rear case 102. Various electric/electronic parts are loaded in a space provided between the front and rear cases 101 and 102. Optionally, at least one middle case can be further provided between the front and rear cases 101 and 102 in addition.
The cases 101 and 102 are formed by injection molding of synthetic resin or can be formed of metal substance such as stainless steel (STS), titanium (Ti) or the like for example.

FIG. 2B is a perspective diagram of a backside of the terminal shown in FIG. 2A.
Referring to FIG. 2B, a camera 121′ can be additionally provided to a backside of the terminal body, and more particularly, to the rear case 102. The camera 121 has a photographing direction that is substantially opposite to that of the former camera 121 shown in FIG. 21A and may have pixels differing from those of the firmer camera 121.
Preferably, for instance, the former camera 121 has low pixels enough to capture and transmit a picture of user's face for a video call, while the latter camera 121′ has high pixels for capturing a general subject for photography without transmitting the captured subject. And, each of the cameras 121 and 121′ can be installed at the terminal body to be rotated or popped up.
A flash 123 and a mirror 124 are additionally provided adjacent to the camera 121′. The flash 123 projects light toward a subject in case of photographing the subject using the camera 121′. In case that a user attempts to take a picture of the user (self-photography) using the camera 121′, the mirror 124 enables the user to view user's face reflected by the mirror 124.
An additional audio output unit 152′ can be provided to the backside of the terminal body. The additional audio output unit 152′ is able to implement a stereo function together with the former audio output unit 152 shown in FIG. 2A and may be used for implementation of a speakerphone mode in talking over the terminal.
A broadcast signal receiving antenna 124 can be additionally provided to the lateral side of the terminal body as well as an antenna for communication or the like. The antenna 124 constructing a portion of the broadcast receiving module 111 shown in FIG. 1 can be retractably provided to the terminal body.
A power supply unit 190 for supplying a power to the terminal 100 is provided to the terminal body. And, the power supply unit 190 can be configured to be built within the terminal body. Alternatively, the power supply unit 190 can be configured to be detachably connected to the terminal body.
A touchpad 135 for detecting a touch can be additionally provided to the rear case 102. The touchpad 135 can be configured in a light transmittive type like the display unit 151. In this case, if the display unit 151 is configured to output visual information from its both faces, it is able to recognize the visual information via the touchpad 135 as well. The information outputted from both of the faces can be entirely controlled by the touchpad 135. Alternatively, a display is further provided to the touchpad 135 so that a touchscreen can be provided to the rear case 102 as well.
The touchpad 135 is activated by interconnecting with the display unit 151 of the front case 101. The touchpad 135 can be provided in rear of the display unit 151 in parallel. The touchpad 135 can have a size equal to or smaller than that of the display unit 151.
Interconnected operational mechanism between the display unit 151 and the touchpad 135 are explained with reference to FIG. 3A and FIG. 3B as follows.
FIG. 3A and FIG. 3B are front-view diagrams of a terminal according to one embodiment of the present invention for explaining an operational state thereof.
First of all, various kinds of visual information can be displayed on the display unit 151. And, these information can be displayed in characters, numerals, symbols, graphics, icons and the like.
In order to input the information, at least one of the characters, numerals, symbols, graphics and icons are represented as a single predetermined array to be implemented in a keypad formation. And, this keypad formation can be so-called ‘soft keys’.
FIG. 3A shows that a touch applied to a soft key is inputted through a front face of a terminal body.
The display unit 151 is operable through an entire area or by being divided into a plurality of regions. In the latter case, a plurality of the regions can be configured interoperable.
For instance, an output window 151a and an input window 151b are displayed on the display unit 151. A soft key 151c representing a digit for inputting a phone number or the like is outputted to the input window 151b. If the soft key 151c is touched, a digit corresponding to the touched soft key is outputted to the output window 151a. If the first manipulating unit 131 is manipulated, a call connection for the phone number displayed on the output window 151a is attempted.
FIG. 3B shows that a touch applied to a soft key is inputted through a rear face of a terminal body. If FIG. 3A shows a case that the terminal body is vertically arranged (portrait), FIG. 3B shows a case that the terminal body is horizontally arranged (landscape). And, the display unit 151 can be configured to change an output picture according to the arranged direction of the terminal body.
FIG. 3B shows that a text input mode is activated in the terminal.
An output window 151a′ and an input window 151b′ are displayed on the display unit 151. A plurality of soft keys 151c′ representing at least one of characters, symbols and digits can be arranged in the input window 151b′. The soft keys 151c′ can be arranged in the QWERTY key formation.
If the soft keys 151c′ are touched through the touchpad (cf. ‘135’ in FIG. 2B), the characters, symbols and digits corresponding to the touched soft keys are outputted to the output window 151a′. Thus, the touch input via the touchpad 135 is advantageous in that the soft keys 151c′ can be prevented from being blocked by a finger in case of touch, which is compared to the touch input via the display unit 151. In case that the display unit 151 and the touchpad 135 are configured transparent, it is able to visually check fingers located at the backside of the terminal body. Hence, more correct touch inputs are possible.
Besides, the display unit 151 or the touchpad 135 can be configured to receive a touch input by scroll. A user scrolls the display unit 151 or the touchpad 135 to shift a cursor or pointer located at an entity (e.g., icon or the like) displayed on the display unit 151. Furthermore, in case that a finger is shifted on the display unit 151 or the touchpad 135, a path of the shifted finger can be visually displayed on the display unit 151. This may be useful in editing an image displayed on the display unit 151.
To cope with a case that both of the display unit (touchscreen) 151 and the touchpad 135 are touched together within a predetermined time range, one function of the terminal can be executed. The above case of the simultaneous touch may correspond to a case that the terminal body is held by a user using a thumb and a first finger (clamping). The above function can include activation or deactivation for the display unit 151 or the touchpad 135.
FIG. 4 is a flowchart for a method of controlling a mobile terminal according to the present invention.
Referring to FIG. 4, the controller 180 activates a 1st application file via a specific application [S410]. In this case, application files including the 1st application file may mean files that can be activated via the specific application. The touchscreen 151 may display a 1st file image corresponding to the 1st application file in a single view state [S420]. Subsequently, the touchscreen 151 may receive a pinch-in touch gesture from a user in the single view state [S430]. In response to the reception of the pinch-in touch gesture, the controller 180 may be able to enter a multi-view state for displaying a plurality of file images [S440].
After the step S440, a specific file image is selected from the plurality of file images and may then switch to the single view state. In particular, the touchscreen 151 may receive a selection of a specific file image selected from a plurality of file images displayed in the multi-view state [S450]. Subsequently, the controller 180 activates a specific application file corresponding to the selected specific file image and may then control the specific file image to be displayed in the single view state [S460].
Meanwhile, the terminology called ‘single view state’ mentioned in the specification may mean a state in which a single image is displayed on the touchscreen 151. For example, when a music A file is played via a music play application, if a single view state is entered, a music A image (album A image) related to the music A file may be displayed on the touchscreen 151. On the other hand, the terminology called ‘multi-view state’ mentioned in this specification is conceptionally opposite to the single view state and may mean a state in which a plurality of images are displayed on the touchscreen 151. For instance, when a music play application is activated in the same manner of the above example, if a multi-view state is entered, a plurality of images including a music A image (album A image) related to a music A file, a music B image (album B image) related to a music B file, and a music C image (album C image) related to a music C file, and the like may be displayed on the touchscreen 151 together.
According to the present invention, various control operations may be activated in the mobile terminal 100 in response to a pinch-in touch gesture or a pinch-out touch gesture. In the following description, the pinch-in touch gesture and the pinch-out touch gesture are explained.
First of all, the pinch-in/out touch gesture may basically mean a touch gesture performed in a manner of touching two touch points on the touchscreen 151 and then increasing or decreasing a relative distance between the two touch points. In doing so, the touch gesture of decreasing or increasing the relative distance between the two touch points may include a flicking touch gesture performed in a manner of flicking a finger or a drag touch gesture performed in a manner of pulling or pushing the touch points.
Although the terminology ‘pinch in/out’ is usable to represent the corresponding touch gesture as a pinching action. The present invention may be non-limited by such a pinch action as the pinch-in/out action. And, all kinds of touch gestures of increasing or decreasing a relative distance between two touched points may be applicable to the present invention.
If the controller 180 receives the pinch-in/out touch gesture, the controller 180 may be able to perform a control operation corresponding to the received pinch-in/out touch gesture. In accordance with the meaning indicated by the two touch points by the pinch-in/out touch gesture, a different control operation may be performed. For instance, in case that two touch points by a pinch-in/out touch gesture belong to a specific icon displayed on the touchscreen 151, a target of a control operation by the pinch-in/out touch gesture may include the specific icon. Optionally, a control operation can be performed irrespective of locations of touch points. For instance, in response to a pinch-in/out touch gesture performed by a user in a manner of touching two random points on the touchscreen 151, it may be able to control a whole image displayed on the touchscreen 151 to be reduced/enlarged.
According to the present invention, there may exist various kinds of control operations by pinch-in/out touch gestures. With reference to FIGS. 5 to 8, an operation of switching to a multi-view state in the course of activating an application is described as one example of the control operation by the pinch-in/out touch gesture. With reference to FIG. 9 and FIG. 10, an operation of changing a hierarchical structure of images (icons or file images) is described as another example of the control operation by the pinch-in/out touch gesture. With reference to FIG. 11 and FIG. 12, an operation of changing information displayed on an icon displayed on a home screen or activating an application corresponding to an icon is described as a further example of the control information by the pinch-in/out touch gesture.
In the following description, embodiments according to the follow of the mobile terminal controlling method described with reference to FIG. 4 are explained with reference to FIGS. 5 to 8.
FIGS. 5 to 8 show examples of a control operation by a pinch-in/out touch gesture, in which control operations of switching a single view state to a multi-view state by a pinch in touch gesture in the course of activating a specific application are shown.
FIG. 5 is a diagram for one example of a multi-view state switching operation in association with a music application in response to a pinch-in touch gesture according to the present invention.
Referring to FIG. 5 (a), while the controller 180 activates a music application for playing a specific music file, the touchscreen 151 may display a music image related to the active specific music file. Referring to the drawing, a 1st album image 530a related to an album having the specific music file belong thereto is being displayed on the touchscreen 151. In doing so, the 1st album image 530a is displayed in a single view state on the touchscreen 151. If a pinch-in touch gesture for decreasing a relative distance between two touch points 510a and 510b is received from a user via the touchscreen 151, the controller 180 may recognize the received pinch-in touch gesture as a user command for switching to a multi-view state.
Hence, the controller 180 may be able to switch to the multi-view state for displaying the 1st album image 530a of the currently active specific music file and other album images on the touchscreen 151.
Referring to FIG. 5 (b), in response to the pinch-in touch gesture, a plurality of the album images 530a to 530f including the 1st album image 530a related to the currently active specific music file may be displayed on the touchscreen 151 in the multi-view state.
In doing so, if the user continues the pinch-in touch gesture for decreasing the relative distance between the two touch points 510a and 510b, it may be able to reduce a plurality of the album images in the multi-view state. Optionally, if the user continues the pinch-in touch gesture, it may be able to reduce the 1st album image 530a related to the active music file only among a plurality of the album images in the multi-view state.
Meanwhile, if the single view state is switched to the multi-view state, an active status of the corresponding specific music file may be displayed on the album image. For instance, referring to FIG. 5 (b), if the single view state of displaying the 1st album image 530a only is switched to the multi-view state in response to the pinch-in touch gesture, the 1st album image 530a in the multi-view state may represent an active status (e.g., information on a track number in the album) of the corresponding specific music file at the timing point of the pinch-in touch gesture. In the drawing, the 1st album image 530a represents ‘7’ as the information on the track number in the album. Moreover, after an active status of a specific music file, which was active right before initiation of a pinch-in touch gesture, has been exactly analyzed, the specific music file of the active status can be saved in the memory 160. Hence, if the corresponding specific music file is selected again, it may be able to resume the specific music file in continuation with the previously active point.
Referring to FIG. 5(c), a plurality of the album images 530a to 530e in the multi-view state are reduced in response to the pinch-in touch gesture. While the pinch-in touch gesture is continuing, the album images in the multi-view state are reduced, whereby more album images may be displayed on the touchscreen 151.
Meanwhile, since a plurality of the album images 530a to 530e are displayed in the multi-view state, in order to discriminate the music file activated right before the initiation of the pinch-in touch gesture and the 1st album image 530a related to the corresponding music file from the rest of the album images 530b to 530e, an outline of the 1st album image 530a may be highlighted or shaded.
Referring to FIG. 5 (c), a touch gesture 540 is performed to select a specific album image 530b from a plurality of album images 530a to 530e displayed on the touchscreen 151.
Referring to FIG. 5 (d), in response to the selection of the specific album image 530b, the controller 180 may be able to activate a specific music file related to the specific album image 530b. Moreover, the controller 180 switches to the single view state to control the touchscreen 151 to display the specific album image 530b only. Moreover, when the specific music file is activated, the controller 180 may control the specific music file saved in the memory 160 to be played in a manner of starting with a most recently played portion of the specific music file.
Meanwhile, when the pinch-in touch gesture is continuing in the multi-view state, the controller 180 may control the corresponding music application to be ended.
FIG. 6 is a diagram for one example of a multi-view state switching operation in association with a word processor application in response to a pinch-in touch gesture according to the present invention.
Referring to FIG. 6 (a), a specific word file is created by activating a word processor application. As a state of creating a specific word file, the touchscreen 151 may display a 1st word file image 630a in a single view state. In doing so, the 1st word file image 630 may represent a state in which an ongoing word file currently created by a user keeps changing bit by bit. In particular, the word file image is the image that represents a word file activated by the word processor application.
In doing so, if a pinch-in touch gesture is performed to decrease a relative distance between two touch points 610a and 610b, the controller 180 may switch to a multi-view state in which several word file images are displayable for the word processor application.
Referring to FIG. 6 (b), in response to the pinch-in touch gesture, a plurality of file images 630a and 630b are displayed on the touchscreen 151. A creation window for creating a new word file or a 3rd word file image 630c may be displayed on the touchscreen 151 as well as the 1st word file image 630a related to the previously created word file shown in FIG. 6 (a) and the 2nd word file image 630b related to another word file.
Referring to FIG. 6 (b), each of a plurality of the word file images 630a and 630b may be able to represent whether the word file related to the corresponding word file image has been saved. In the drawing, the 1st word file image 630a uses the indication ‘∘’ to indicate that the related word file has not been saved, while the 2nd word file image 630b uses the indication ‘•’ to indicate that the related word file has been saved.
Another pinch-in touch gesture is shown in FIG. 6 (b). If the pinch-in touch gesture is performed once more in the multi-view state shown in FIG. 6 (b) or is continuing, the state shown in FIG. 6 (c), or optionally, the state shown in FIG. 6 (d) may be entered.
First of all, FIG. 6 (c) shows that summary information on each of the word file images is provided as the pinch-in touch gesture is continuing in the multi-view state. Each of the word file images 630a and 630b may be able to emphasize the summary information on the corresponding word file while the multi-view state continues. For instance, a content of a corresponding word file can be provided in summary to a user in a manner that a head line or title of the corresponding word file gradually appears in response to the pinch-in touch gesture.
Referring to FIG. 6 (d), as the pinch-in touch gesture is continuing in the multi-view state, it can be observed that a list view state is entered to display a list 640 of the word files. In particular, the continuation of the pinch-in touch gesture in the multi-view state enables the controller 180 to switch to the list view state.
In case that the 2nd word file image 630b is selected in FIG. 6 (c), it may be able to display the 2nd word file image 630b on the touchscreen 151 in the single view state shown in FIG. 6 (e). Moreover, it may be able to activate the word file related to the 2nd word file image 630b via the word processor application.
According to the above description, in case that the pinch-in touch gesture continues in the multi-view state shown in FIG. 6 (b), the summary information display operation shown in FIG. 6 (c) or the list view state display operation shown in FIG. 6 (d) is performed. For another instance, in case that the pinch-in touch gesture continues in the multi-view state shown in FIG. 6 (b), the summary information display operation shown in FIG. 6 (c) may be performed. If the pinch-in touch gesture continues in FIG. 6 (c), it may be able to switch to the list view state shown in FIG. 6 (d).
FIG. 7 is a diagram for one example of a multi-view state switching operation in association with an image editing application in response to a pinch-in touch gesture according to the present invention.
Referring to FIG. 7 (a), as an image editing application is activated, a specific image file may be edited. In doing so, the touchscreen 151 may display a 1st image 720a related to the specific image n a single view state. In doing so, if a pinch-in touch gesture for decreasing a relative distance between two touch points 710a and 710b is performed, the controller 180 may switch the single view state to a multi-view state for displaying several images for the image editing application.
Referring to FIG. 7 (b), in response to the pinch-in touch gesture, a plurality of images 710a and 710b are displayed on the touchscreen 151. When the multi-view state is entered in response to the pinch-in touch gesture, the relative distance between the two touch points 710a and 710b decreases and a size of the 1st image 710 decreases in proportion to the relative distance. In particular, if the relative distance between the two touch points 710a and 710b decreases in response to the pinch-in touch gesture, the 1st image 710a displayed in the single view state on the touchscreen 151 shown in FIG. 7 (a) is correspondingly displayed in a manner that the size of the 1st image 710a is decreased.
Referring to FIG. 7 (c), a plurality of images 720a and 720b are displayed in the multi-view state in response to the pinch-in touch gesture. A creation window for creating a new image or a 3rd image 720c is displayed as well as the 1st image 720a related to the image filed edited in FIG. 7 (a) and the 2nd image 720b related to another image file.
In association with FIG. 7 (c), each of a plurality of the images 720a and 720b may be able to indicate whether its corresponding image file is saved. In the drawing, the 1st image 720a may use an indication ‘•’ to indicate that the related image file is saved. And, the 2nd image 720 may use an indication ‘∘’ to indicate that the related image file is not saved.
In FIG. 7 (c), shown is a touch gesture for selecting the 2nd image 720b from a plurality of the images 720a and 720b displayed in the multi-view state. After a specific image has been selected in the multi-view state, the controller 180 switches the multi-view state to a single view state and may then control the selected image on a full screen.
Referring to FIG. 7 (d), the 2nd image 720b selected in response to the selection action shown in FIG. 7C is displayed in the single view state on the touchscreen 151. In doing so, the 2nd image 720b may be displayed in the previous state for editing the 2nd image.
In association with FIG. 7, the exact state of the ongoing job in case of the initiation of the pinch-in touch gesture in the course of displaying an image in the single view state can be held as it is. And, an image file related to this image in the edited state can be exactly saved in the memory 160.
FIG. 8 is a diagram for one example of a multi-view state switching operation in association with an internet application in response to a pinch-in touch gesture according to the present invention.
Referring to FIG. 8, after a specific site has been accessed by activating an internet application, if a pinch-in touch gesture is performed in the course of displaying an image of the corresponding site, other site images may be displayed. And, another site image may be displayed in response to a selection action or gesture.
Referring to FIG. 8 (a), after an internet application has been activated, a specific site is accessed. And, a 1st site image 820b corresponding to the specific site is displayed in a single view state on the touchscreen 151. In doing so, a pinch-in touch gesture may be performed to decrease a relative distance between two touch points 810a and 810b. While the specific site image 820b is displayed via the internet application, if such a pinch-in touch gesture as shown in the drawing is received, the controller 180 may switch to a multi-view state and may display other site images.
Referring to FIG. 8 (b), a plurality of site images 820a to 820c may be displayed in the multi-view state on the touchscreen 151. And, the site image 820a and 820c related to other sites previously activated via the internet application may be displayed as well as the 1st site image related to the activated site.
In response to a pinch-in touch gesture, the touchscreen 151 may display the 1st site image 820b in a manner of decreasing a size of the 1st site image 820b. In dong so, the size of the 1st site image 820b may be determined in a manner of depending on positions of two touch points 810a and 810b according to the pinch-in touch gesture.
Meanwhile, the reduced 1st site image 820b may represent summary information on the corresponding site on its front surface in response to the pinch-in touch gesture. In particular, as soon as the pinch-in touch gesture is performed on the 1st site image 820b, the information on the corresponding site, i.e., the summary information on the 1st site image 820b (e.g., ‘Naver is my competitive power’) may be briefly represented by the 1st site image 820b. 
Referring to FIG. 8 (c), in response to the ongoing pinch-in touch gesture in the state shown in FIG. 8 (b), a plurality of the image sites 820a to 820c are displayed in equal size in the multi-view state. As mentioned in the foregoing descriptions with reference to FIGS. 5 to 7, if another site image is selected in the multi-view state shown in FIG. 8 (c), the multi-view state can be switched to the single view state and the selected site image can be displayed on the touchscreen 151.
In the following description, an operation of changing a hierarchical structure of images (e.g., icons, file images, etc.) displayed on the touchscreen 151 by a different control operation in response to a pinch-in/out touch gesture is explained with reference to FIG. 9 and FIG. 10.
First of all, it may be able to adjust sizes of a plurality of images displayed on the touchscreen 151 in response to a pinch-in/out touch gesture. In doing so, if the pinch-in/out touch gesture exceeds a predetermined level, it may be able to display an image of a step above or below the predetermined level. For instance, while a plurality of file images are displayed on the touchscreen 151, assume a case that a pinch-in touch gesture for reducing an image is received. It may be able to decrease sizes of displayed file images within a prescribed range. If a pinch-in touch gesture continues over a specific level, it may be able to display a higher level image of the file images, e.g., a directory image. On the contrary, in case of a pinch out touch gesture, it may be able to display a lower layer image.
FIG. 9 is a diagram for an operation of changing a hierarchical structure of images displayed in response to user's continuous pinch-in touch gesture on a home screen image according to the present invention.
Referring to FIG. 9 (a), a single file image 910a is displayed on the touchscreen 151. In the drawing, while the file image 910a is displayed, a user performs a pinch-in touch gesture on the touchscreen 151 to decrease a relative distance between two touch points 905a and 905b. 
In case that a pinch-in touch gesture is performed on a whole region of the touchscreen 151, an image displayed on the touchscreen 151 may be displayed in a manner of being entirely reduced. In particular, the controller 180 recognizes that the relative distance between the two touch points 905a and 905b is decreased in response to the pinch-in touch gesture and may be then able to reduce the image displayed on the touchscreen 151.
Referring to FIG. 9 (b), the whole image is reduced in response to the pinch-in touch gesture shown in FIG. 9 (a). Although FIG. 9 (a) shows that the single file image 910a is displayed on the touchscreen 151 only, the touchscreen 151 may be able to display a plurality of images 910a to 910i in response to a user's pinch-in touch gesture.
Referring to FIG. 9 (b), the pinch-in touch gesture for decreasing the relative distance between the two touch points 905a and 905b keeps being performed on the touchscreen 151.
Referring to FIG. 9 (c), the touchscreen 151 displays a control operation of a next level in response to the pinch-in touch gesture. Although a plurality of the file images 910a to 910i are displayed on the touchscreen 151 shown in FIG. 9 (b), it may be able to change a hierarchical structure of the images displayed in response to a user's pinch-in touch gesture. In particular, the touchscreen 151 may be able to display a directory image 920a including a plurality of the file images 910a to 910i. In more particular, the file image display step of the lower layer step for displaying the file images 910a to 910i may be switched to the directory image display step of a middle layer step for displaying the directory images 920a to 920d in response to the pinch-in touch gesture.
Meanwhile, a timing point of changing a layer may be determined by a user or may be determined in advance by a manufacturer. Instead of increasingly reducing or enlarging sizes of images in response to a pinch-in touch gesture or a pinch-out touch gesture, once a specific interval is entered, it may be able to change a layer of images. And, the specific interval or timing point may be determined in advance.
Referring to FIG. 9 (c), another pinch-in touch gesture is performed on the touchscreen 151 again to decrease the relative distance between the two touch points 910a and 910b. 
Referring to FIG. 9 (d), the touchscreen 151 displays a next layer step in response to the pinch-in touch gesture shown in FIG. 9 (c). In case that the pinch-in touch gesture keeps being performed in FIG. 9 (c), the directory image 920a may be reduced. If the pinch-in touch gesture further keeps being performed, an application icon image 930a may be displayed as shown in FIG. 9 (d). In particular, in the middle layer step, the directory images 920a to 920d are displayed. If the pinch-in touch gesture continues, the middle layer step may be switched to a higher layer step, i.e., an application icon display step of displaying application icons 930a to 930d. 
For clarity of the following description, the directory images 920a to 920d may be explained as the images related to directory files executed in the word application related to the word application icon image 930a. 
In summary of the control operation shown in FIG. 9 (a) to FIG. 9 (d), in response to a user's continuous pinch-in touch gesture, an image on the touchscreen 151 is reduced and displayed, initially displayed file images are switched to directory images corresponding to upper layers of the file images, the upper layers of the file images are displayed, the directory images are switched to application icon images corresponding to higher layers of the directory images, and the application icon images are then displayed.
The operation of changing the hierarchical structure, as shown in FIG. 9 (a) to FIG. 9 (d), is applied in association with a photo image is described as follows.
First of all, if a pinch-in touch gesture is performed in a detail view state for displaying a single photo image on the touchscreen 151, the single photo image may be displayed in a manner of being reduced in size. If the pinch-in touch gesture keeps being performed in this state, the detail view state may be switched to a thumbnail view state in which a plurality of photo images are displayed as thumbnail images on the touchscreen 151. Subsequently, if the pinch-in touch gesture keeps being performed in this state, the thumbnail images may be displayed in the thumbnail view state in a manner that the thumbnail images are reduced in size and that the number of the thumbnail images increases. In particular, if the number of thumbnail images displayed in an initial thumbnail view state is 3*5, the number of thumbnail images may increase to 4*7 in response to the pinch-in touch gesture and may further increase to 5*9. If the pinch-in touch gesture keeps being performed in the thumbnail view state, the thumbnail view state may be switched to an album view state. Thus, if a pinch-in touch gesture is applied to a photo image, a size of an image may be decreased in response to the pinch-in touch gesture, a detail view state may be switched to a thumbnail view state, and the thumbnail view state may be switched to an album view state. On the contrary, if a pinch-out touch gesture is applied to a photo image, a size of an image may be increased in response to the pinch-out touch gesture, an album view state may be switched to a thumbnail view state, and the thumbnail view state may be switched to a detail view state.
In the drawings, referring to FIG. 9 (e) and FIG. 9 (f), in case that the pinch-in touch gesture keeps being performed on the touchscreen 151, a display region on the touchscreen 151 is reduced and the touchscreen 151 eventually enters a touch lock state.
Referring to FIG. 9 (e), as the ongoing pinch-in touch gesture shown in FIG. 9 (d) continues, a control operation is performed to have a display region of the touchscreen 515 limited to a specific region 940. In particular, all images displayed on the touchscreen 151 are displayed in a manner of being reduced.
Referring to FIG. 9 (f), in response to the continuous pinch-in touch gesture, the touchscreen 151 enters a touch lock state.
Regarding the changes of the display operations shown in FIGS. 9 (a) to 9 (f), the changes may be performed continuously. In particular, as the pinch-in touch gesture continues, icons may be reduced in size with continuity as well. Moreover, a switching to a directory image from a file image and a switching to an application icon image from the directory image may be consecutively changed.
Although the pinch-in touch gesture for decreasing the relative distance between the two touch points 905a and 905b is described with reference to FIGS. 9 (a) to 9 (e), the description with reference to FIGS. 9 (a) to 9 (e) may be applicable to a pinch-out touch gesture for increasing the relative distance between the two touch points 905a and 905b. In general, in case of the pinch-out touch gesture, a function opposite to that of the pinch-in touch gesture may be performed.
In particular, in case that a pinch-out touch gesture is performed in the touchscreen lock state shown in FIG. 9 (f), a touchscreen unlock state shown in FIG. 9 (e) may be entered. If the pinch-out touch gesture continues in the state shown in FIG. 9 (e), the state shown in FIG. 9 (e) may be changed into the state shown in FIG. 9 (d) in a manner that an image region 940 is enlarged. If the pinch-out touch gesture still continues in the state shown in FIG. 9 (d) (i.e., higher layer step), the state shown in FIG. 9 (d) may be switched to the directory image display (i.e., middle layer step) shown in FIG. 9 (c).
If the layer structure is changed like the state shown in FIG. 9 (d) is changed into the state shown in FIG. 9 (c), a reference for determining a layer structure to be changed for a prescribed application icon image may be required. For instance, since a plurality of application icon images 930a to 930d are displayed in FIG. 9 (d), it may be necessary to determine a middle layer step for a prescribed application icon image in case of performing a pinch-out touch gesture. Hence, the controller 180 selects an application icon image displayed in a largest size on the touchscreen 180 and may be then able to switch to the middle layer step of the selected application icon image. Alternatively, a user directly selects a prescribed application icon image from a plurality of application icon images and may enable a middle layer step of the selected prescribed application icon image to be entered. This principle may be identically applicable to a case of switching directory images to file images.
Thus, if the pinch-out touch gesture keeps being performed, the states may be changed in order of FIG. 9 (f), FIG. 9 (e), FIG. 9 (d), FIG. 9 (c), FIG. 9 (b) and FIG. 9 (a), which is reverse to that of the pinch-in touch gesture.
FIG. 10 is a diagram for an operation of changing a hierarchical structure of a display image in response to user's continuous pinch-in touch gesture on a calendar display screen according to the present invention.
Referring to FIG. 10, through a pinch-in/out touch gesture, icons or images may be enlarged/reduced and each display step may be switched to a higher step or a lower step. For instance, considering a calendar display screen, when the touchscreen 151 displays a day state, if a pinch-in touch gesture is performed, the day state may be switched to a week state. Moreover, when the touchscreen 151 displays the week state, if a pinch-out touch gesture is performed, the week state may be switched to the day state.
Referring to FIG. 10 (a), as a calendar application is activated, a calendar display screen is displayed. In particular, the touchscreen 151 displays a day state image 1010 for a day in the calendar display screen. In doing so, if a pinch-in touch gesture for decreasing a relative distance between two touch points 1015a and 1015b is performed, the day state image 101 may be switched to a week state image 1020.
Referring to FIG. 10 (b), the day state image 1010 is reduced and the week state image 1020 is displayed. In doing so, if the pinch-in touch gesture keeps being performed, the day state image may be completely switched to the week state image 1020 for displaying the week state only, as shown in FIG. 10 (c). In case that the day state image 1010 is still displayed, as shown in FIG. 10 (b), information ‘D14’ indicating what date is the corresponding day may be displayed.
Referring to FIG. 10 (c), if the pinch-in touch gesture for decreasing the relative distance between the two touch points 1015a and 1015b in the displayed week state image 1020 is performed, the week state image 1020 may be switched to a month state image 1030.
Referring to FIG. 10 (d), in response to the pinch-in touch gesture, the week state image 1020 keeps being reduced and the touchscreen 151 displays the month state image. In doing so, if the pinch-in touch gesture continues, referring to FIG. 10 (e), the week state image 1020 disappears and the month state image 1030 is displayed. In doing so, the initial day state image 1010 may be highlighted and displayed in the month state image 1030.
Meanwhile, regarding the calendar application, the above description is made just on the assumption of the pinch-in touch gesture. Yet, the same description may apply to a pinch-out touch gesture. For instance, in response to the pinch-out touch gesture, a year state image may be switched to a month state image, the month state image may be switched to a week state image, and the week state image may be switched to a day state image.
In the following description, for another example of a control operation by a pinch-in/out touch gesture, an operation of changing information indicated by an icon displayed on a home screen and an operation of activating an application corresponding to an icon are explained with reference to FIG. 11 and FIG. 12.
FIG. 11 is a diagram for one example of an operation of changing information indicated by an icon displayed in a home screen image in response to a pinch-out touch gesture according to the present invention.
According to the present invention, a home screen image or information indicated by an icon may be changed using a pinch-out touch gesture. For instance, in case that a pinch-out touch gesture keeps being performed, a size of an icon displayed in a home screen image is increased and information indicated by a specific icon may be modified in response to the pinch-out touch gesture.
In particular, in case that a relative distance between two touch points is increased in response to a pinch-out touch gesture, an icon displayed in a home screen image may be displayed in a manner that a size of the icon is increased. In accordance with a progress level of the pinch-out touch gesture, an information on an application related to a specific icon is modified, the modified information may be represented by the specific icon, and the application related to the specific icon may be activated.
For instance, in accordance with a progress extent of a pinch-out touch gesture, a 1st step may be set to increase a size of a specific icon only in response to the pinch-out touch gesture. In a 2nd step next to the 1st step, an actual active state information of an application indicated by a specific icon may be displayed as well as a size of the specific icon is increased. In a 3rd step, if a size of an icon is increased over a predetermined level, an application indicated by the corresponding icon is actually activated and the touchscreen 151 may be set to display an active application image in a single view state.
Referring to FIG. 11 (a), a home screen image of the mobile terminal 100 is displayed on the touchscreen 151. In doing so, the home screen image may be displayed on the touchscreen 151 in a manner of including a plurality of icons 1110a to 1110e. Subsequently, a pinch-out touch gesture is performed in a manner of touching two specific points 1120a and 1120b of a specific icon 1110a among a plurality of the icons 1110a to 1110e and then increasing a relative distance between the touched two specific points 1120a and 1120b. In FIG. 11, the specific icon 1110a, which is a touch target of the pinch-out touch gesture, is the icon related to a message application.
Referring to FIG. 11 (b), as the pinch-out touch gesture is performed on the specific icon 1110a, the selected specific icon 1110a is displayed in a manner that its size is increased. In particular, if the relative distance between the two touch points 1120a and 1120b is increased in response to the pinch-out touch gesture, the selected specific icon 1110a is displayed in a manner that its size is increased. In doing so, sizes of the rest of the icons 1110b to 1110e may be increased as well as the size of the specific icon 1110a. Yet, the size of the specific icon 1110a, which is the target of the pinch-out touch gesture, is optionally increased only, while the sizes of the rest of the icons 1110b to 1110e remain intact.
The specific icon 1110a shown in FIG. 11 (b) differs from the former specific icon 1110a shown in FIG. 11 (a). In particular, the former specific icon 1110a shown in FIG. 11 (a) represents simple information indicating that the number of received messages is 3 in the message application, but the latter specific icon 1110a shown in FIG. 11 (b) may actually represent a content of one of the received messages. In particular, the information represented via the specific icon 1110a may be changeable as well as the display size of the specific icon 1110a is increased.
Referring to FIG. 11 (c), if the pinch-out touch gesture continues, the specific icon 1110a represents a changed information. In particular, a content of another received message of the message application related to the specific icon 1110a can be represented by the specific icon 1110a as well as the size of the specific icon 1110a is increased.
Referring to FIG. 11 (d), if the pinch-out touch gesture further continues, the message application indicated by the specific icon 1110a may be actually activated. And, an active screen image of the message application may be displayed on a full screen of the touchscreen 151 in a single view state. Hence, it may be able to display an active operation of the message application on the full screen of the touchscreen 151. In doing so, a reference for actually activating the message application in response to the pinch-out touch gesture may be variously set to one of a case that the size of the icon 1110a displayed on the touchscreen is equal to or greater than a predetermined level, a case that a relative distance between two touch points of the pinch-out touch gesture is equal to or greater than a predetermined level, and the like.
Referring to FIG. 11 (e), after the message application has been activated, an initialized state is shown. In comparison with FIG. 11 (a), FIG. 11 (e) shows a state that the indication of the received messages has disappeared from the specific icon 1110a as several messages of the message application has been checked in response to the pinch-out touch gesture.
Meanwhile, when a pinch-out touch gesture is performed, a different control operation may be performed in association with whether a user releases his fingers from the touchscreen 151. For instance, after a pinch-out touch gesture has been initiated, if the user keeps touching the touchscreen 151, the icon display state shown in one of FIGS. 11 (a) to 11 (c) may be displayed on the touchscreen 151. Yet, if the user releases his fingers from the touchscreen after the initiation of the pinch-out touch gesture, the application activated state may be displayed on the touchscreen 151, as shown in FIG. 11 (d).
FIG. 12 is a diagram for another example of an operation of changing information displayed on an icon displayed on a home screen image in response to a pinch-out touch gesture according to the present invention.
With reference to FIG. 11, an operation of changing an information represented by a single icon 110a in response to a pinch-out touch gesture is described. Yet, with reference to FIG. 12, an operation of changing an information represented by each of several icons by increasing sizes of the several icons simultaneously in response to a pinch-out touch gesture shall be described as follows.
Referring to FIG. 12 (a), a plurality of icons 1210a to 1210d and the like configuring a home screen are displayed on the touchscreen 151. And, a pinch-out touch gesture for increasing a relative distance between two touch points 1210a and 1210b corresponding to a specific region is shown in the drawing. Comparing FIG. 12 with FIG. 11, the pinch-out touch gesture shown in FIG. 11 (a) is the touch gesture performed on the two touch points 1120a and 1120b of the specific icon 110a, while the pinch-out touch gesture shown in FIG. 12 (a) is the touch gesture performed on the two touch points 1210a and 1210b of a random specific region on the touchscreen 151 rather than the specific icon 1220a. 
Referring to FIG. 12 (b), a plurality of the icons 1210a to 1210d are displayed in a manner that sizes of a plurality of the icons 1210a to 1210d are increased in response to the pinch-out touch gesture performed on the specific region. Moreover, applications respectively related to a plurality of the icons 1210a to 1210d may be activated and each of a plurality of the icons 1210a to 1210d may be able to represent an information on each of the applications. For instance, the 1st icon 1220a relates to a message application, the 2nd icon 1220b relates to a document application, the 3rd icon 1220c relates to an internet application, and the 4th icon 1220d relates to a call application. Hence, as the relative distance between the two touch points is increased in response to the pinch-out touch gesture, each of the icons may represent the corresponding application information as soon as sizes of the icons are increased.
In the drawing, the 1st icon 1220a may represent the information on an active state of the message application and the 3rd icon 1220c may represent the information on an active state of the internet application. In particular, recent state information on the application represented by each of the icons in response to the pinch-out touch gesture may be schematically checked.
In FIG. 12 (b), a user may be able to change the information indicated by each of the icons. The active state information on a specific icon may be changeable, as shown in the drawing, while a plurality of the icons represent active state information on a plurality of applications, respectively. For instance, when the 1st icon 1220a is selected and touch-scrolled, other message contents of a text message application may be checked. In doing so, the unselected 3rd icon 1220c may be maintained as it is.
Moreover, in case of attempting to check a state of each application in further detail, it may be able to directly activate the corresponding application by selecting each icon.
Referring to FIG. 12 (c), a user performs an action to select the 1st icon 1220a from a plurality of the icons 1220a to 1220d. Referring to FIG. 12 (d), as the 1st icon 1220a is selected, an active image 1240 of a message application related to the 1st icon 1220a may be displayed on a full screen of the touchscreen 151 in a single view state.
FIG. 13 is a diagram for an operation of enlarging an icon temporarily in association with an initiation of a pinch-in/out touch gesture according to the present invention.
According to the present invention, in case of attempting to enlarge or reduce an icon by a pinch-in/out touch gesture, a target (e.g. an icon, an image, etc.) to be enlarged or reduced may have a size too small to select two touch points. Hence, the present invention temporarily increases a size of the icon to enlarge or reduce prior to the pinch-in/out touch gesture, more particularly, the pinch-out touch gesture, thereby facilitating a user to touch the corresponding icon.
Referring to FIG. 13, a plurality of icons 1310a to 1310d are displayed on the touchscreen 151.
Referring to FIG. 13 (b), if a specific icon 1310a among the icons 1310a to 1310d is slightly touched, a size of the touched icon 1310a may be increased. Hence, a user performs a pinch-out touch gesture by multi-touching two points belonging to the enlarged icon 1310a, thereby further enlarging the corresponding icon.
Referring to FIG. 13 (c), the size of the specific icon 1310a is increased in response to the pinch-out touch gesture.
According to one embodiment of the present invention, the above-described methods can be implemented in a program recorded medium as computer-readable codes. The computer-readable media include all kinds of recording devices in which data readable by a computer system are stored. The computer-readable media include ROM, RAM, CD-ROM, magnetic tapes, floppy discs, optical data storage devices, and the like for example and also include carrier-wave type implementations (e.g., transmission via Internet).
Accordingly, embodiments of the present invention provide various effects and/or features.
First of all, a mobile terminal according to the present invention switches an active application file into another application file using a user-friendly pinch-in/out touch gesture.
Secondly, a mobile terminal according to the present invention facilitates a specific application to be quickly activated using a pinch-in/out touch gesture performed on a touchscreen.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions.
