This application claims priority under 35 U.S.C. §119 to Korean Application No. 10-2012-0081799, filed on Jul. 26, 2012, whose entire disclosure(s) is/are hereby incorporated by reference.
1. Field
The present invention relates to a terminal, and more particularly, to a terminal and method of sharing a handwriting therein. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for sharing a handwriting input applied to the terminal with an external terminal.
2. Background
Generally, terminals can be classified into mobile/portable terminals and stationary terminals. The mobile terminals can be classified into handheld terminals and vehicle mount terminals again according to possibility of user's direct portability.
As functions of the terminal are diversified, the terminal is implemented as a multimedia player provided with composite functions such as photographing of photos or moving pictures, playback of music or moving picture files, game play, broadcast reception and the like for example.
Moreover, the terminal expands its roles into a scheduler function for simple memo input and storage, schedule management and the like. Recently, in order to reinforce the scheduler function, a terminal tends to be designed for enabling a user to input a handwriting without activating an application separately.
However, a method of sharing a handwriting input applied to a terminal with an external device has not been developed yet. For instance, while a presentation is made in a seminar or the like, only a person, who is manipulating a computer provided to make the presentation, is able to apply a handwriting input to a presentation material. And, there is no way for other persons to apply a handwriting input to the presentation material. In case that a presentation listening person has an instant idea in the course of the presentation, it may cause a problem of an absence of a means or method for recording the instant idea.
Thus, the demand for effectively performing a handwriting input on an external terminal via a terminal is rising.
Accordingly, embodiments of the present invention are directed to a terminal and method of sharing a handwriting therein that substantially obviate one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a terminal and method of sharing a handwriting therein, by which convenience of user's manipulation is enhanced.
In particular, one object of the present invention is to provide a terminal and method of sharing a handwriting therein, by which a handwriting input can be performed on an external terminal using a terminal.
Another object of the present invention is to provide a terminal and method of sharing a handwriting therein, by which a handwriting input applied to an external terminal can be displayed.
Additional advantages, objects, and features of the invention will be set forth in the disclosure herein as well as the accompanying drawings. Such aspects may also be appreciated by those skilled in the art based on the disclosure herein.

First of all, the wireless communication unit 110 typically includes one or more components which permits wireless communication between the terminal 100 and a wireless communication system or network within which the 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 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 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 terminal 100 using status measurements of various aspects of the terminal. For instance, the sensing unit 140 may detect an open/close status of the terminal 100, relative positioning of components (e.g., a display and keypad) of the terminal 100, a change of position of the terminal 100 or a component of the terminal 100, a presence or absence of user contact with the terminal 100, orientation or acceleration/deceleration of the terminal 100. As an example, consider the terminal 100 being configured as a slide-type terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the 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 terminal 100. For instance, if the 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 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 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 terminal 100 in accordance with the implemented configuration of the terminal 100. For instance, a plurality of display units can be arranged on a single face of the 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 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.

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 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 terminal 100 in accordance with the corresponding configuration type of the terminal 100.
The projector module 155 is the element for performing an image projector function using the 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 terminal 100. And, it is understood that the projector module 155 can be provided to any portion of the 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 terminal 100. Examples of such data include program instructions for applications operating on the 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 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 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 terminal 100 or enables data within the 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 terminal 100 and can include User Identify Module (UIM), Subscriber Identity 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 terminal 100 via the corresponding port.
When the terminal 110 is connected to an external cradle, the interface unit 170 becomes a passage for supplying the 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 terminal 100. Each of the various command signals inputted from the cradle or the power can operate as a signal enabling the terminal 100 to recognize that it is correctly loaded in the cradle.
The controller 180 typically controls the overall operations of the 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.
The power supply unit 190 provides power required by the various components for the terminal 100. The power may be internal power, external power, or combinations thereof.

A handwriting input sharing method according to the present invention may be described in a manner of being categorized into a first sharing method in aspect of a touch input providing terminal and a second sharing method in aspect of a touch input receiving terminal. In particular, according to the first sharing method, the touch input providing terminal provides a touch input applied to a touchscreen of its own to an external terminal 200 and then controls a trace of the touch input to be displayed via the external terminal 200. And, according to the second sharing method, the touch input receiving terminal is provided with a touch input applied to the external terminal 200 and then displays a trace of the touch input on a touchscreen of its own.
In more particular, the handwriting input sharing method may be categorized into the first sharing method or the second sharing method depending on whether a touch input is inputted via a touchscreen of a terminal or an external terminal.

The controller 180 may control the touchscreen 151 to output the same content of the external terminal 200 or may control the touchscreen 151 and the external terminal 200 to output different contents, respectively. In case that the touchscreen 151 and the external terminal 200 are set to output the same content, if a wireless network is established between the wireless communication unit 110 and the external terminal 200, the terminal 100 may be set to share a content saved in the memory 160 with the external terminal 200 or may be set to share a content saved in the external terminal 200 [S302]. On the other hand, if the touchscreen 151 and the external terminal 200 are set to output different contents, respectively, the above-mentioned step S302 may be skipped.
In particular, if a content provided by the terminal 100 is set to be shared with the external terminal 200, the controller 180 may control the content saved in the memory 160 to be provided to the external terminal 200. In doing so, the external terminal 200 displays the content received from the terminal 100 and may be then able to control the same content of the terminal 100 to be outputted.
On the other hand, if the content saved in the external terminal 200 is set to be shared with the terminal 100, the controller 180 may be able to control the wireless communication unit 110 to receive a content file from the external terminal 200. Once the wireless communication unit 110 receives the content from the external terminal 200, the controller 180 outputs the received content to the touchscreen 151, thereby controlling the terminal 100 and the external terminal 200 to output the same content.
Meanwhile, the contents mentioned in the above description may include various kinds of multimedia data used as backgrounds of handwriting inputs as image files, video files, e-book files, document files, broadcast data and the like.

In the examples mentioned in the above description, the terminal 100 establishes a wireless network with a single external terminal 200 only. Yet, it may be unnecessary for the terminal 100 and the external terminal 200 to perform one-to-one communication only. And, the terminal 100 may be able to configure a wireless network with a plurality of external terminals 200.
For instance, while the terminal 100 is configuring a wireless network with a first external terminal 200, if a second external terminal 200 makes a request for an access to the wireless network, the terminal 100 may accept or reject the request made by the second external terminal 200. A trace of a touch input from the second external terminal 200 is displayed on the first external terminal 200, the first external terminal 200 may display the results of the handwritings performed on the terminal 100 and the second external terminal. Hence, in order to prevent a handwriting action of a user of the terminal 100 from being interrupted, the access requested by the end external terminal 200 may need an approval of the first external terminal 200.
Once the second external terminal 200 is admitted into the wireless network, the controller 180 may display a content outputted via the second external terminal 200 or may be able to control the trace of the touch input to be further displayed on the second external terminal 200.
In case that the terminal 100 is set to share handwriting inputs, as mentioned in the foregoing description with reference to
In the following description, the second sharing method is described in detail with reference to the accompanying drawings.

If the external terminal 200, with which a content will be shared, is selected, referring to
Yet, it may be unnecessary for each of the touchscreen 151 and the external terminal 200 to output the same content. Even if the touchscreen 151 and the external terminal 200 output different contents, respectively, a handwriting result via the external terminal 200 may be outputted via the touchscreen 151. In case that the touchscreen 151 and the external terminal 200 output the different contents, respectively, the step S902 shown in
The controller 180 of the terminal 100 according to the present invention may be able to control an object, which represents the external terminal 200 forming a wireless network with the wireless communication unit 110, to be displayed via the touchscreen 151. Moreover, the controller 180 may be able to control an object representing the handwriting input authority granted external terminal 200 and an object representing the handwriting input authority non-granted external terminal 100 to be visually discriminated from each other. In this case, the object may include such an indicator capable of indicating a connection to the external terminal 200 as an icon, a cursor, an image, a text and the like. For clarity of the following description, assume that the object representing the external terminal 200 is displayed as an icon.
Referring to
In the example shown in
Moreover, while the wireless network is configured with the external terminal 200, the controller 180 may be able to control a real-time monitoring image of the external terminal 200 to be outputted via the touchscreen 151. By displaying the real-time monitoring image, a handwriting content drawn on the external terminal 200 is checked and outputs of the touchscreen 151 and the external terminal 200 can be compared to each other.
Referring to
Moreover, even if a handwriting is drawn on the handwriting input authority non-granted external terminal 200, a user may use a monitoring image of the corresponding external terminal 200 to check a prescribed content of the corresponding handwriting.
The controller 180 may be able to configure a monitoring image to compare screens before and after a handwriting activity through the external terminal 200. For instance, referring to
In case that a trace of a touch input applied to the external terminal 200 is displayed on the touchscreen 151 as well as on the external terminal 200, the controller 180 may be able to control a monitoring image not to be displayed on the touchscreen 151 while the trace of the touch input is being drawn. This is to prevent the trace of the touch input drawn on the touchscreen 151 from being blocked by the monitoring image.

Referring now to
In the example shown in
In order to display a trace of a touch input applied via the handwriting input authority granted external terminal 200, the wireless communication unit 110 may be able to receive a handwriting layer or coordinates information of the touch input from the external terminal 200. The controller 180 may control the handwriting layer received via the wireless communication unit 110 to be outputted via the touchscreen 151 or may control the touch input trace to be displayed on the touchscreen 151 in a manner that a point matching the coordinated information is visually identifiable. Moreover, in case that the external terminal 200 and the touchscreen 151 differ from each other in specifications, the controller 180 may be able to control a display size of the trace of the touch input received from the external terminal 200 to fit the specifications of the touchscreen 151 appropriately. For instance, if the size of the touchscreen 151 of the external terminal 200 is 1 inch and the size of the touchscreen 151 of the terminal 100 is 2 inches, the terminal 100 displays the trace of the touch input twice larger than the external terminal 200 does. In particular, the controller 180 may be able to adjust a display size of the handwriting result based on a ratio of resolution, screen size or the like between the external terminal 200 and the touchscreen 151.
Yet, in case that a touch input is applied to the handwriting input authority granted external terminal 200, it may be unnecessary for a trace of the touch input to be displayed via the touchscreen 151. In case that a user of the handwriting input authority grated external terminal 200 sets a handwriting input not to be shared, the controller 180 may control a trace of the touch input applied via the external terminal 200 not to be displayed on the touchscreen 151. For instance, as mentioned in the foregoing description with reference to
In case that a touch input is applied via the external terminal 200, the controller 180 may control an indicator to be outputted via the touchscreen 151 to indicate that the touch input is being applied to the external terminal 200 via the touchscreen 151.
Referring to
In the example shown in
In case that touch input traces from a plurality of external terminals are displayed on the touchscreen 151, the controller 180 may control the touch input traces to be displayed on the touchscreen 151 in a manner that different visual effects are given to a plurality of the external terminals 200, respectively. For instance, in case that a trace of a first touch input applied via a first external terminal 200 and a trace of a second touch input applied via a second external terminal 200 are displayed on the touchscreen, the controller 180 may control the trace of the first touch input and the trace of the second touch input to be displayed in a first color and a second color, respectively.
Referring to
Moreover, the controller 180 may be able to control colors of icons 1511 and 1513 representing the external terminals 200 to match the colors of the touch input traces displayed on the touchscreen 151, respectively. For instance, the icon 1511 representing the external terminal 200 named Jane may be displayed in the first color on the touchscreen 151 and the icon 1513 representing the external terminal 200 named Knoster may be displayed in the second color on the touchscreen 151.
Moreover, even if the touch input traces from a plurality of the external terminals 200 are displayed on the touchscreen 151, the controller 180 may be able to selectively display the touch input trace from at least one of a plurality of the external terminals 200 in response to a user input. For instance, in case that a trace of a first touch input inputted via a first external terminal 200 and a trace of a second touch input inputted via a second external terminal 200 are displayed on the touchscreen 151, the controller 180 may control either the trace of the first touch input or the trace of the second touch input to be displayed via the touchscreen 151 only by a user manipulation.
Referring to
For instance, referring to
The controller 180 may be able to selectively display at least one of a plurality of handwriting results displayed on the touchscreen 151, as shown in
Moreover, the controller 180 merges a content displayed on the touchscreen 151 with at least one of a plurality of the handwriting results and may then control the merged result to be saved.
Referring to
For clarity of the foregoing description, the terminal 100 in the first sharing method is assumed as the smart phone and the terminal 100 in the second sharing method is assumed as the smart TV. Yet, it may be unnecessary for the terminals 100 used by the first and second sharing methods to differ from each other. And, it is a matter of course that the terminals of the same kind can become the terminals 100 in the first and second sharing methods. Moreover, one terminal 100 is an entity of the first sharing method and may also become an entity of the second sharing method. In other words, the terminal 100 is a providing terminal that provides the external terminal 200 with a trace of a touch input and may also play a role as a receiving terminal that receives a trace of a touch input from the external terminal 200.
For instance, the controller 180 of the terminal 100 displays a trace of a touch input applied to the touchscreen 151 and may also control a trace of a touch input, which is applied to the external terminal, to be displayed at the same time. In particular, both of the trace of the touch input applied to the touchscreen 151 and the trace of the touch input applied to the external terminal 200 can be simultaneously displayed on the touchscreen 151. In doing so, referring to
