Referring to FIG. 1, the A/V input unit 120 is used to input an audio signal or a video signal and can include a camera 121 and a microphone 122. The camera 121 processes image frames of still images or moving images obtained by an image sensor in a video telephony mode or a photographing mode. The processed image frames can be displayed on a display module 151.
The image frames processed by the camera 121 can be stored in the memory 160 or transmitted to an external device through the radio communication unit 110. The mobile terminal 100 can include at least two cameras according to constitution of the terminal.
The microphone 122 receives an external audio signal in a call mode, a recording mode or a speed recognition mode and processes the received audio signal into electric audio data. The audio data can be converted into a form that can be transmitted to a mobile communication base station through the mobile communication module 112 and output in the call mode. The microphone 122 can employ various noise removal algorithms for removing noise generated when the external audio signal is received.
The user input unit 130 receives input data for controlling the operation of the terminal from a user. The user input unit 130 can include a keypad, a dome switch, a touch pad (constant voltage/capacitance), jog wheel, jog switch and so on.
As shown in FIG. 1, the A/V input unit 120 and the user input unit 130 can be realized as a single input unit 116. Various kinds of input data generated at the input unit 116 can be used to activate a handwriting input through a display unit 151 implemented in the form of a touch screen. The input data can comprise images received through the camera 121, voice of a user received through the microphone 122, and touch signals received through the display unit 151. However, the scope of the present invention is not limited to the above.
The sensing unit 140 senses the current state of the mobile terminal 100, such as open/close state of the mobile terminal 100, the position of the mobile terminal 100, whether a user touches the mobile terminal 100, the direction of the mobile terminal 100 and acceleration/deceleration of the mobile terminal 100 and generates a sensing signal for controlling the operation of the mobile terminal 100. For example, the sensing unit 140 can sense whether a slide phone is opened or closed when the mobile terminal 100 is the slide phone. Furthermore, the sensing unit 140 can sense whether the power supply 190 supplies power and whether the interface 170 is connected to an external device. The sensing unit 140 can include a proximity sensor.
The output unit 150 generates visual, auditory or tactile output and can include the display module 151, an audio output module 152, an alarm module 153 and a haptic module 154.
The display module 151 displays information processed by the mobile terminal 100. For example, the display module 151 displays UT or graphic user interface (GUI) related to a telephone call when the mobile terminal is in the call mode. The display module 151 displays a captured or/and received image, UI or GUI when the mobile terminal 100 is in the video telephony mode or the photographing mode.
The display module 151 can include at least one of a liquid crystal display, a thin film transistor liquid crystal display, an organic light-emitting diode display, a flexible display and a three-dimensional display.
Some of these displays can be of a transparent type or a light transmission type. This can be referred to as a transparent display. The transparent display includes a transparent liquid crystal display. The rear structure of the display module 151 can also be of the light transmission type. According to this structure, a user can see an object located behind the body of the mobile terminal 100 through an area of the body of the mobile terminal 100, which is occupied by the display module 151.
The mobile terminal 100 can include at least two display modules 151 according to constitution of the terminal. For example, the mobile terminal 100 can include a plurality of displays that are arranged on a single face at a predetermined distance or integrated. Otherwise, the plurality of displays can be arranged on different sides.
When the display module 151 and a sensor sensing touch (referred to as a touch sensor hereinafter) form a layered structure, which is referred to as a touch screen hereinafter, the display module 151 can be used as an input device in addition to an output device. The touch sensor can be in the form of a touch film, a touch sheet and a touch pad, for example.
The touch sensor can be constructed such that it converts a variation in pressure applied to a specific portion of the display module 151 or a variation in capacitance generated at a specific portion of the display module 151 into an electric input signal. The touch sensor can be constructed such that it can sense pressure of touch as well as the position and area of touch.
When touch input is applied to the touch sensor, a signal corresponding to the touch input is transmitted to a touch controller. The touch controller processes the signal and transmits data corresponding to the processed signal to the controller 180. Accordingly, the controller 180 can detect a touched portion of the display 151.
Referring to FIG. 1, the proximity sensor 141 can be located in an internal region of the mobile terminal, surrounded by the touch screen, or near the touch screen. The proximity sensor senses an object approaching a predetermined sensing face or an object located near the proximity sensor using electromagnetic force or infrared rays without having mechanical contact. The proximity sensor has lifetime longer than that of a contact sensor and has wide application.
The proximity sensor includes a transmission type photo-electric sensor, a direct reflection type photo-electric sensor, a mirror reflection type photo-electric sensor, a high-frequency oscillating proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, an infrared proximity sensor, etc.
A capacitive touch screen is constructed such that proximity of a pointer is detected through a variation in an electric field according to the proximity of the pointer. In this case, the touch screen (touch sensor) can be classified as a proximity sensor.
For convenience of explanation, an action of approaching the pointer to the touch screen while the pointer it not being in contact with the touch screen such that location of the pointer on the touch screen is recognized is referred to as “proximity touch” and an action of bring the pointer into contact with the touch screen is referred to as “contact touch” in the following description. A proximity touch point of the pointer on the touch screen means a point of the touch screen to which the pointer corresponds perpendicularly to the touch screen when the pointer proximity-touches the touch screen.
The proximity sensor senses proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch velocity, a proximity touch time, a proximity touch position, a proximity touch moving state, etc.). Information corresponding to the sensed proximity touch action and proximity touch pattern can be displayed on the touch screen.
The audio output module 152 can output audio data received from the radio communication unit 110 or stored in the memory 160 in a call signal receiving mode, a telephone call mode or a recording mode, a speech recognition mode and a broadcasting receiving mode. The audio output module 152 outputs audio signals related to functions (for example, a call signal incoming tone, a message incoming tone, etc.) performed in the mobile terminal 100. The audio output module 152 can include a receiver, a speaker, a buzzer, etc.
The alarm module 153 outputs a signal for indicating generation of an event of the mobile terminal 100. Examples of events generated in the mobile terminal include receiving of a call signal, receiving of a message, input of a key signal, input of touch, etc. The alarm module 153 can output signals in forms different from video signals or audio signals, for example, a signal for indicating generation of an event through vibration. The video signals or the audio signals can be also output through the display module 151 or the audio output module 152.
The haptic module 154 generates various haptic effects that the user can feel. A representative example of the haptic effects is vibration. The intensity and pattern of vibration generated by the haptic module 154 can be controlled. For example, different vibrations can be combined and output or sequentially output.
The haptic module 154 can generate a variety of haptic effects including an effect of stimulus according to arrangement of pins vertically moving for a contact skin face, an effect of stimulus according to jet force or sucking force of air through a jet hole or a sucking hole, an effect of stimulus rubbing the skin, an effect of stimulus according to contact of an electrode, an effect of stimulus using electrostatic force and an effect according to reproduction of cold and warmth using an element capable of absorbing or radiating heat in addition to vibrations.
The haptic module 154 can not only transmit haptic effects through direct contact but also allow the user to feel haptic effects through kinesthetic sense of his fingers or arms. The mobile terminal 100 can include at least two haptic modules 154 according to constitution of the mobile terminal.
The memory 160 can store a program for the operation of the controller 180 and temporarily store input/output data (for example, phone book, messages, still images, moving images, etc.). The memory 160 can store data about vibrations and sounds in various patterns, which are output from when a touch input is applied to the touch screen.

The interface 170 receives data from the external devices or power and transmits the data or power to the internal components of the mobile terminal 100 or transmits data of the mobile terminal 100 to the external devices.
The interface 170 can include a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for connecting a device having a user identification module, an audio I/O port, a video I/O port, an earphone port, etc., for example.
An identification module is a chip that stores information for authenticating the authority to use the mobile terminal 100 and can include a user identify module (UIM), a subscriber identify module (SIM) and a universal subscriber identify module (USIM). A device (referred to as an identification device hereinafter) including the identification module can be manufactured in the form of a smart card. Accordingly, the identification device can be connected to the mobile terminal 100 through a card slot included in the interface 170.
So far, with reference to FIG. 1, structure of a mobile terminal 100 according to the present invention has been described. In what follows, characteristics of a mobile terminal 100 according to the present invention carrying out a memo function will be described in more detail.
FIG. 2 is a flow diagram illustrating a method for generating a memo file for a mobile terminal according to an embodiment of the present invention. In response to the user's operation, the controller 180 of the mobile terminal 100 activates a handwriting input function employing a touch screen 151 of the mobile terminal 100, S100. According to the present invention of this document, the user can perform a touch motion against the touch screen 151 by using his or her body part (e.g., a finger), a stylus pen, and the like. Furthermore, the user can perform a handwriting input motion through the touch screen 151.
If a handwriting input function is activated, the controller 180 deactivates the execution screen of a particular application displayed on the touch screen 151, S110. For example, while in the activation state, a touch on a particular area of the execution screen of a particular application causes a function corresponding to the particular area to be performed; however, in the deactivation state, a function corresponding to the particular area is not performed even if a touch is sensed on the particular area.
Here, a particular application may include an application for operating the mobile terminal 100 as well as an application for carrying out a particular function such as a phone application, a memo application, a web browsing application, and so on. Therefore, the execution screen of the particular application can correspond to an execution screen of an application for carrying out a particular function, a lock-screen (which is an execution screen of an operating application), a waiting screen, and so on.
FIG. 3 illustrates a procedure of a user's activating a handwriting input function of the mobile terminal 100 on a lock screen according to the method for generating a memo file illustrated in FIG. 2. FIG. 4 is a screen of the mobile terminal 100 with a handwriting input function activated according to the method for generating a memo file illustrated in FIG. 2.
With reference to FIG. 3, the user, touching a soft key 151A corresponding to a handwriting input function displayed in an indicator area, can activate a handwriting input function employing the touch screen 151. Though not shown in FIG. 3, the user can also activate a handwriting input function employing the touch screen 151 by pressing a hardware key included in the mobile terminal 100.
In what follows, with reference to FIG. 4, characteristics found on the screen 151 of the mobile terminal 100 will be examined when a handwriting input function is activated. If a handwriting input function employing the touch screen 151 is activated, the controller 180 decreases a transparency of an execution screen of the particular application, thereby changing the execution screen of the particular application into a translucent state. Then the user, checking that the execution screen of the particular application has been changed into a translucent state, can recognize that the execution screen of the particular application has been deactivated. It should be noted that the controller 180 does not perform a lock-release function for the mobile terminal 100 in the state of FIG. 3 even if the user performs a touch operation to release lock.
If a handwriting input function employing the touch screen 151 is activated, the controller 180 can display a message window 151B on the screen 151, inquiring whether to include an execution screen of the particular application at the time of creating a memo file. If the user touches a selection button 151B′ of the message window 151B, the controller 180 can generate a memo file by using at least part of the execution screen of the particular application. A method for generating a memo file by using an execution screen of a particular application will be described in detail with reference to FIGS. 23 to 38.
Also, if a handwriting input function employing the touch screen 151 is activated, the controller 180 can display a pop-up window 151C on the screen 151 of the mobile terminal 100 for a predetermined time, the pop-up window displaying a message that a character or an image can be input through handwriting since a handwriting input function has been activated.
In addition, if a handwriting input function employing the touch screen 151 is activated, the controller 180 can display a setting area 151D for selecting a style for a line generated through handwriting input on the screen 151 of the mobile terminal 100. At this time, the style of a line generated through handwriting input can include color, texture, thickness, transparency, and so on; but the scope of the present invention is not limited to the above.
It should be noted that a method for deactivating an activated handwriting input function can include a method of re-touching a soft key 151A corresponding to a handwriting input function while the handwriting input function is activated and a method of pressing a home button 151E, and a method of pressing a back key; but the scope of the present invention is not limited to the above.
As opposed to what are illustrated in FIGS. 3 and 4, if an execution screen of the particular application is updated according to an execution procedure, the controller 180 can update an execution screen of the particular application according to the execution procedure of the particular application while keeping the execution screen of the particular application in a deactivation state.
FIG. 5 is a procedure through which an execution screen of an SNS application deactivated upon activation of a memo function is updated according to the execution procedure of the SNS application. With reference to FIG. 5, as new messages are arriving, old messages move subsequently to a downward direction of a screen. Therefore, the user can check the execution procedure of an SNS application even while a handwriting input function is activated.
So far, it has been described with reference to FIGS. 3 to 5 that a handwriting input function of the mobile terminal 100 according to the present invention can be activated in a lock screen and an execution screen of a particular application. However, the handwriting input function of the mobile terminal 100 according to the present invention can be a function included in a memo application.
For example, if a handwriting input function is activated as a memo application is performed while an execution screen of the particular application is displayed on the touch screen 151, the user, checking the execution screen of the particular application being updated, may input handwriting through the touch screen 151, perform an editing function (e.g., copy, paste, cut, etc.) against the handwriting input, or open a memo file and perform an editing function against the memo file. At this time, the execution screen of a memo application can be regarded as a transparent or translucent virtual layer being formed on the execution screen of the particular application and blocking a response of the particular application according to a touch input. In other words, as long as the handwriting input function is activated, the controller 180 of the mobile terminal 100 can update the execution screen of the particular application while keeping the execution screen of the particular application in a deactivation state.
Again, with reference to FIG. 2, if the execution screen of the particular application is deactivated, the touch screen 151 receives handwriting input generated based on a touch input of the user S120. Then the controller 180 converts the received handwriting input into a memo file and store the memo file S130.
FIGS. 6 to 8 illustrate a procedure through which handwriting input received through a touch screen 151 is stored in the form of a memo file according to the method for generating a memo file illustrated in FIG. 2. More specifically, FIGS. 6 to 8 illustrate a procedure through which the controller 180 of the mobile terminal 100 converts handwriting input received being overlapped on a deactivated lock screen into an image file and generates a memo file including the converted image file.
As shown in FIG. 6, the user selects handwriting input 151G displayed on the screen 151 of the mobile terminal 100. Then the controller, as shown in FIG. 7, displays soft keys 151H1, 151 H2 intended to select storage space for a memo to be generated on the screen 151 of the mobile terminal 100. A first soft key 151H1 of the soft keys 151H1, 151H2 is a soft key intended to store the memo file to be generated into the storage space associated with a memo application while a second soft key 151H2 is a soft key for storing the memo file to be generated into clip board.
As shown in FIG. 7, if the user touches the first soft key 151H1, a memo file generated is stored in the storage space associated with the memo application. Then, as shown in FIG. 8, the user can check the generated memo file by activating a memo application in conjunction with the stored memo file. Referring to FIG. 8, it can be seen that a memo file including an image file 151I converted from handwriting input has been stored in the storage space associated with the memo application. FIG. 9 is a flow diagram illustrating one example of a method for generating a memo file for a mobile terminal according to the present invention illustrated in FIG. 2. In what follows, the method for generating a memo file will be described with reference to related drawings.
Handwriting input is received through a touch screen 151 while a handwriting input function is activated S120. If handwriting input is received through the touch screen 151, the controller 180 of the mobile terminal 100 determines whether the handwriting input can be converted to text S131. If it is found that the handwriting input cannot be converted to text, the controller 180 can convert the handwriting input into an image S132 and generate a memo file including the converted image and store the memo file into a storage unit 150.
If the controller 180 determines that the handwriting input can be converted to text, however, the controller 180 displays a pop-up window for deciding whether to convert the handwriting input into an image or text S133. In other words, if the handwriting input can be converted to text, the controller 180 displays a pop-up window for choosing a conversion scheme of the handwriting input. However, if it turns out such that conversion of the handwriting input into text is unattainable, the controller 180 does not display a pop-up window for the user's choosing a conversion scheme on the screen 151 of the mobile terminal 100.
Next, the controller 180 determines whether the user makes a choice for converting the handwriting input into text S134. If the user makes a choice for converting the handwriting input into an image through the pop-up window, the controller 180 converts the handwriting input into an image S132. However, if the user makes a choice for converting the handwriting input into text, the controller 180 can convert the handwriting input into text S135 and generate a memo file including the converted text and stored the memo file in a storage unit 150.
FIG. 9 illustrates a case where the controller 180 displays a pop-up window for choosing a conversion scheme of the handwriting input on the screen 151 in the case that handwriting input can be converted into text. However, depending on embodiments of the present invention, the controller 180 can convert the handwriting input directly into text without providing a pop-up window for choosing a conversion scheme of the handwriting input.
FIGS. 10 to 11 illustrate a procedure of generating a memo file including text 151K converted from handwriting input 151G according to a method for generating a memo illustrated in FIG. 9.
Referring to FIG. 10, it can be known that if the handwriting input 151G can be converted to text, the controller 180 of the mobile terminal 100 displays a pop-up window 151J for choosing a conversion scheme of the handwriting input on the screen 151. As shown in FIG. 10, while a pop-up window 151J is displayed, the user makes a choice to convert the handwriting input into text through the pop-up window 151J. Then the controller 180 converts the handwriting input into text and generates a memo file including converted text and stores the memo file. Then, as shown in FIG. 11, the user can check the memo file including the text 151K converted from the handwriting input by activating a memo application.
So far, a method for storing handwriting input received through a touch screen 151 into a memo file has been described with reference to FIGS. 2 to 11. The mobile terminal 100 according to the present invention, however, can convert the handwriting input into an image or text and store temporality the converted handwriting input into a clipboard instead of storing the handwriting input in a memo file. In what follow, an example of using handwriting input by storing the handwriting input into a clipboard will be described with reference to FIGS. 12 to 16.
FIG. 12 is a flow diagram illustrating a method for using handwriting input for the mobile terminal 100 according to an embodiment of the present invention. In what follows, a method for using the handwriting input will be described with reference to related drawings.
Handwriting input is received through a touch screen 151 while a handwriting input mode is activated S120. Then, the controller 180 of the mobile terminal 100 converts the handwriting input into text and/or image and stores the converted handwriting input in a clipboard S140. Depending on settings, the text and/or image can be stored automatically into the clipboard or stored into the clipboard according to the user's selection. A procedure through which the handwriting input is converted can be performed in the same manner as or in a way similar to the method described with reference to FIGS. 2 to 11; therefore, a detailed description thereof will be omitted. If the converted text and/or image is stored in the clipboard, the controller 180 carries out a particular application based on the user's operation S150. At this point, it is desirable for a particular application to be capable of carrying out functions of paste, delete, and copy against text, image, and so on. While the particular application is running, the controller 180 receives a long-touch from the user against an execution screen of the particular application S160. Here, the long-touch of the user corresponds to a right mouse click in a computer system.
If a long-touch against an execution screen of the particular application is received, the controller 180 displays a pop-up window for pasting an execution screen of the particular application with text and/or image stored in the clipboard S170. Next, if the user's touch is received against the pop-up window, the controller 180 performs pasting the stored text and/or image S180.
In the following, one example of a method for using handwriting input illustrated in FIG. 12 will be described with reference to FIGS. 13 to 16. FIGS. 13 to 16 illustrate a procedure of carrying out a method for using handwriting input illustrated in FIG. 12.
Referring to FIG. 13, the user touches a second soft key 151H2 while handwriting input 151G is displayed on the screen 151. Then, the controller 180 converts the handwriting input 151G into text and stores the converted text into a clipboard.
As shown in FIG. 14, while the converted text is stored in the clipboard, the user carries out a schedule application and makes a long-touch against the execution screen of the schedule application. Then, the controller 180, as shown in FIG. 15, displays a pop-up window 151M for pasting the text stored in the clipboard to the execution screen of the schedule application on the execution screen of the schedule application.
Next, as shown in FIG. 15, if the user touches an area of the pop-up window corresponding to a paste function, the controller 180 pastes the text 151K stored in the clipboard to the execution screen of the schedule application as shown in FIG. 16.
FIG. 17 is a flow diagram illustrating another example of a method for generating a memo file for the mobile terminal 100 according to the present invention illustrated in FIG. 2. More specifically, FIG. 17 is a flow diagram illustrating a method for generating a memo file by using all of handwriting input received through a touch screen 151 and an execution screen of a particular application displayed on the touch screen 151. In what follows, the method for generating a memo file will be described with reference to related drawings.
While a handwriting input mode is activated, handwriting input is received through a touch screen 151, S120. Then the controller 180 of the mobile terminal 100 extracts part of the handwriting input which can be converted into text S190.
Next, the controller 180 converts part of the handwriting input inconvertible to text into an image S200 whereas the part convertible to text is converted into text or image S210. A procedure of converting the part of handwriting input convertible to text into text or image can be performed in the same manner as or in a way similar to the method described with reference to FIGS. 2 to 11; therefore, a detailed description thereof will be omitted.
If conversion of the handwriting input into text and/or image is completed, the controller 180 generates a memo file including the converted text and/or image and stores the generated file S220.
In what follows, examples of the method for generating a memo file will be described with reference to FIGS. 18 to 22. FIGS. 18 to 22 illustrate procedures of generating a memo file according to a method for generating a memo file illustrated in FIG. 17.
With reference to FIG. 18, the user inputs handwriting to the screen 151 of a touch screen 151. Then the controller 180 extracts from the handwriting those parts convertible to text 151G, 151G1, 151G2 and regards the remaining part of the handwriting as the part 151G3 impossible for conversion to text.
FIG. 19 illustrates a case where the controller 180 converts the whole of handwriting input 151G, 151G1, 151G2, 151G3 into images 151I, 151I1, 151I2, 151I3 and generates a memo file based on the images converted.
FIG. 20 illustrates a case where the controller 180 converts only part 151G1 of those text convertible handwriting inputs 151G, 151G1, 151G2 into text; converts the remaining part 151G2, 151G3 into images; converts part 151G3 of handwriting input inconvertible to text into an image; and generates a memo file based on the above conversion.
Here, the part converted to text from among those text-convertible handwriting inputs 151G, 151G1, 151G2 may have been selected by the user. In other words, the controller 180 can convert at least part 151G1 of those convertible to text 151G, 151G1, 151G2 from among the handwriting input received 151G, 151G1, 151G2, 151G3 into text according to the user's selection.
FIG. 21 illustrates a case where the controller 180 converts text-convertible handwriting inputs 151G, 151G1, 151G2 into a plurality of text group 151K, 151K1, 151K2; converts the part 151G3 inconvertible to text into an image 151I3; and generates a memo file based on the above conversion. Also, it can be seen from the FIG. 21 that the controller 180 has generated a memo file by taking account of the position of handwriting.
Comparing FIGS. 21 and 22, the controller 180 may not consider the position of handwriting input at the time of converting handwriting input into text and/or image. At this time, as shown in FIG. 22, the user can selectively move a text group converted by taking the position of handwriting input into consideration.
In a method for generating a memo file and a method for using handwriting input in the mobile terminal 100 according to the present invention described above, considered was only the handwriting input obtained through a touch screen 100 by the user. However, the description below with reference to FIGS. 23 to 38 indicates that the mobile terminal 100 can perform a function similar to the method for generating a memo and the method for using handwriting input by using both handwriting input and the execution screen of a particular application displayed on a current touch screen 151.
FIG. 23 is a flow diagram illustrating another example of a method for generating a memo file for the mobile terminal 100 according to the present invention illustrated in FIG. 2. More specifically, FIG. 23 is a flow diagram illustrating a method for generating a memo file by using both handwriting input received through a touch screen 151 and an execution screen of a particular application displayed on a touch screen 151. In what follows, a method for generating a memo file will be described with reference to related drawings.
In response to the user's operation, the controller 180 of the mobile terminal 100 activates a handwriting function which uses a touch screen 151 of the mobile terminal 100, S100. If a handwriting function is activated, the controller 180 deactivates the execution screen of a particular application displayed on a touch screen 151, S110.
After the execution screen of the particular application is deactivated, the touch screen 151 receives handwriting input generated based on the user's touch input S120. Then, the controller 180 generates a memo file including a capture image of the execution screen of the particular application and stores the memo files S230. At this time, the handwriting input received can be included in the memo file after being converted into text or image according to the description provided with reference to FIGS. 2 to 22. In what follows, examples of a method for generating a memo file illustrated in FIG. 23 will be described with reference to FIGS. 24 to 29.
FIGS. 24 to 27 illustrate one example of generating a memo file according to a method for generating a memo file illustrated in FIG. 23.
As shown in FIG. 24, if the user touches a soft key 151A corresponding to handwriting input, the controller 180 activates a handwriting input function and deactivates the execution screen 151N of a particular application. Next, the controller 180 can display a message window on the screen 151, inquiring whether to generate a memo file by using the execution screen 151N of the particular application.
If the user selects a selection button 151B′ of the message window, the selection button 151B′ is displayed as shown in FIG. 25. Then, the controller 180 can use both handwriting input received through the touch screen 151 and the execution screen 151N of the particular application for generating a memo file.
FIG. 25 illustrates that the user provides handwriting 151G′ overlapping the execution screen of the particular application and touches a first soft key 151H1 to store the handwriting. Then, as shown in FIG. 26, the controller 180 generates a memo file including both a capture image 151N′ of the execution screen of the particular application and the image 151I′ converted from the handwriting; and stores the memo file.
At this time, the capture image 151N′ of the execution screen of the particular application and the image 151I′ converted from handwriting input can be stored as a single combined image; as shown in FIG. 27, they can be included in the memo file while retaining the respective independence.
Referring to FIG. 27, it can be seen that if the capture image 151N′ of the execution screen of the particular application and the image 151F converted from the handwriting input are independent of each other, the user can select the image 151I′ converted from the handwriting input and move the selected image. Though not shown in the figure, the user can perform the function of copy, paste, and so on by selecting the image 151I′ converted from the handwriting input. This applies the same to the capture image 151N′ of the execution screen of the particular application.
FIGS. 28 to 29 illustrate another example of a procedure of generating a memo file according to a method for generating a memo file illustrated in FIG. 23.
FIG. 28 illustrates a case where the user inputs handwriting 151G overlapping the execution screen of the particular application and a first soft key 151H1 to store the handwriting input. Then, as shown in FIG. 29, the controller 180 generates a memo file including both the capture image 151N′ of the execution screen of the particular application and the text 151K converted from handwriting input; and stores the memo file. At this time, as described with reference to FIGS. 26 to 27, the handwriting input 151G can also be incorporated into a memo file in the form of being combined with a capture image 151N′ of the execution screen of the particular application or as an image independent of the capture image.
FIG. 30 is a flow diagram illustrating one example of a method for generating a memo file shown in FIG. 23. In what follows, the method for generating a memo file will be described with reference to related drawings.
While a handwriting input function is activated, handwriting input is received through a touch screen 151, S120. After handwriting is received, the controller 180 of the mobile terminal 100 selects part of an execution screen of a particular application displayed on the touch screen 151 in response to the user's operation S240.
If part of an execution screen of the particular application is selected, the controller 180 generates a memo file based on a capture image of part of an execution screen of the particular application and handwriting input overlapping the part of an execution screen of the particular application S250. At this time, the handwriting input overlapping the part of an execution screen of the particular application can be included into the memo file after being converted into text and/or image based on whether the handwriting input can be converted to text.
FIGS. 31 to 32 illustrate a procedure of generating a memo file including a capture image of part of the execution screen of a particular application according to a method for generating a memo file illustrated in FIG. 30.
FIG. 31 illustrates a case where the user inputs handwriting 151G′ to an execution screen 151N of the particular application and selects part of the execution screen 151N of the particular application by using a drag motion and touches a first soft key 151H1 for generating a memo file.
Referring to FIG. 31, it can be seen that the part not selected from the execution screen of the particular application is processed to be opaque. Therefore, the user can easily recognize the selected part from the execution screen 151N of the particular application. Also, referring to FIG. 31, it can be seen that the user can change a selected area by dragging the corner part of the selected area.
As shown in FIG. 32, if the user touches a first soft key 151H1, the controller 180 generates a memo file including a capture image 151N′′ for the part selected from an execution screen of the particular area and an image 151I′′ converted from the handwriting; and stores the memo file. Also, comparing FIGS. 26 and 32, the memo file illustrated in FIG. 32 has such a difference from that of FIG. 26 that the part of handwriting input not overlapping the selected area from an execution screen of the particular application has not been reflected for generation of a memo file.
FIG. 33 is a flow diagram illustrating one example of a method for generating a memo file illustrated in FIG. 23. In what follows, the method for generating a memo file will be described with reference to related drawings.
Handwriting input is received through a touch screen 151 while a handwriting input function is activated. If handwriting input is received, the controller 180 of the mobile terminal 100 selects part of an execution of a particular application displayed on the touch screen 151 in response to the user's operation S240.
If part of the execution screen of the particular application is selected, the controller 180 extracts the area not included in the part of an execution screen of a particular application S260 and determines whether the handwriting input not included in the selected part of an execution screen of the particular application can be converted into text S270.
If handwriting input not included in the part of an execution screen of a particular application is inconvertible to text, the controller 180 performs image conversion for the handwriting input excluding the handwriting input not included in the part of an execution screen of the particular application S280.
However, if handwriting input not included in the part of an execution screen of a particular application is convertible to text, the controller 180 converts handwriting input not included in the part of an execution screen of a particular application into text S290 and include the converted text in a memo file being generated. In what follows, examples of a method for generating a memo file illustrated in FIG. 33 will be described with reference to FIGS. 34 to 37. FIGS. 34 to 35 illustrate one example of carrying out a method for generating a memo file shown in FIG. 33.
FIG. 34 illustrates a case where the user selects part of an execution screen 151N of a particular application while handwriting input 151G′ is displayed on a screen of the mobile terminal 100 being overlapped with the execution screen of the particular application. Then, handwriting input 151G′ is classified into the portion 151G′1 overlapping the selected part of the execution screen of the particular application and that 151G′2 not overlapping the selected part of the execution screen of the particular application. While the handwriting input 151G′ is classified accordingly, the user touches a first soft key 151H1 for generating a memo file.
Then, referring to FIG. 35, it can be known that the controller 180 of the mobile terminal 100 generates a memo file including a capture image 151N′′ for the selected part of the execution screen of the particular application and an image 151I′2 converted from handwriting input 151G′1 being overlapped with the selected part of the execution screen of the particular application; and stores the generated memo file. The above indicates that since the portion 151G′2 of handwriting input not overlapping the selected part of the execution screen of the particular application is inconvertible to text, the corresponding portion is excluded at the time of conversion to image.
FIGS. 36 to 37 illustrate another example of carrying out a method for generating a memo file illustrated in FIG. 33.
FIG. 36 illustrates a case where the user selects part of an execution screen 151N of a particular application while handwriting input 151G′ is displayed on a screen of the mobile terminal 100 being overlapped with the execution screen of the particular application. Referring to FIG. 36, the handwriting input 151G does not overlap the selected part of the execution screen of the particular application. Under the above state, the user touches a first soft key 151H1 to generate a memo file.
Referring to FIG. 37, then, it can be known that the controller 180 of the mobile terminal 100 generates a memo file including a capture image 151N′′ for the selected part of the execution screen of the particular application and text 151K converted from handwriting 151G1; and stores the generated memo file. The above indicates that since the handwriting input 151G can be converted to text, the handwriting input 151G has been converted into text and included in a memo file even though the handwriting input 151G does not overlap the selected part of the execution screen of the particular application. Different from the illustration of FIGS. 36 to 37, at the time of generating a memo file, the controller 180 may not consider handwriting input convertible to text, not overlapping the selected part of the execution screen of the particular application.
FIG. 38 illustrates a procedure of setting a style for handwriting input in response to a user's operation. More specifically, FIG. 38 illustrates a procedure of changing the color of a line displayed on the screen 151 at the time of the user's handwriting input.
With reference to the setting area 151D illustrated in FIG. 38, it can be seen that the mobile terminal 100 illustrated in FIG. 38 can display handwriting according to the color selected by the user among four colors. Also, if the user selects a particular color displayed in the setting area 151d, the color of a line displaying handwriting can be changed accordingly.
Though not shown in the figure, the mobile terminal 100 according to the present invention can provide a setting area for selecting thickness, texture, transparency, and the like of the line generated through handwriting input. Furthermore, the mobile terminal 100 can provide a setting area for selecting font, size, color, and thickness of text when handwriting input is converted to text.
FIG. 39 is a flow diagram illustrating a method for generating a memo file according to another embodiment of the present invention. More specifically, FIG. 39 is a flow diagram illustrating a method for selecting items displayed on the screen 151 of the mobile terminal 100 and generating a memo file by using the selected items. In what follows, the method for generating a memo file will be described with reference to related drawings.
The controller 180 of the mobile terminal 100 displays a plurality of items on the screen 151, S300. While the plurality of items are displayed on the screen 151, if the user selects a particular item and activates a memo function S310, the controller 180 deactivates the function corresponding to each of the plurality of items S320.
For example, if a particular item displayed on the screen 151 is an item linked to a particular web site and a memo function is activated, the controller 180 does not perform the operation linking to the predetermined web site even if the user selects the particular item. This is because the link function of the particular item with a memo function activated has been deactivated.
If the plurality of items correspond to the items included in an execution screen of a particular application, the controller 180 can update the execution screen (namely, a plurality of items) of the particular application according to the execution procedure of the particular application while keeping the execution screen of the particular application (in other words, a plurality of items) in a deactivated state.
Meanwhile, activation of selection of a particular item and a memo function can be performed at the same time; or the memo function can be activated after the particular item is selected. Also, the particular item can be selected after the memo function is activated.
After selection of a particular item and activation of a memo function are performed, the controller 180 converts the selected item into image or text S330 and generates a memo file including the converted image or text; and stores the generated memo file. As described above, whether to convert the selected item into a memo file including text or image can be determined based on the convertibility of the selected item into text. According to a method for generating a memo file illustrated in FIG. 39, the memo file generated can also be stored into at least one of storage space associated with a memo application and a clipboard.
FIGS. 40 to 43 illustrate a procedure of carrying out one example of a method for generating a memo file illustrated in FIG. 39.
FIG. 40 illustrates a case where the user make a long-touch on a description part 151Y of a particular product corresponding to an image 151X of the particular project from among a plurality of items displayed on a screen, the controller 180 of the mobile terminal 100 selects the description part 151Y of the particular product. With reference to FIG. 41, it can be known that the description part 151Y of the particular product has been selected and the selected part is displayed with a dark color.
As shown in FIG. 41, if the user touches a soft key 151A for activating a memo function while the description part 151Y of the particular product has been selected, the controller 180 activates a memo function and deactivates a function corresponding to each of the plurality of items.
As shown in FIG. 42, the controller 180 displays on the screen 151 a pop-up window 151J for determining whether to store the description part of the selected particular product into text or image. This is because the description part 151Y of the particular product has an attribute which enables the description part to be converted into text.
FIG. 42 illustrates a case where the user selects the description part 151Y of the particular product to be converted into text. As shown in FIG. 43, then the controller 180 converts the description part 151Y of the particular product into text and generates a memo file including the converted text 151Y′.
It should be note that depending on embodiments of the present invention, different from the procedures of FIGS. 40 to 41, the user can also obtain the same result as the performance result of procedures illustrated in FIGS. 40 to 41 by activating a memo function by making a touch on a soft key 151A intended for activating a memo function and selecting the description part 151Y of the product.
Meanwhile, since the method for generation a memo file illustrated in FIG. 39 generates a memo file other than handwriting, a screen in which items are displayed doesn't have to be implemented in the form of a touch screen. If a screen for displaying items is not implemented as a touch screen, the user can select an item displayed on the screen by using a mouse, a remote controller, and the like; and operate a soft key displayed on the screen. This applies the same to a method for generating a memo file illustrated in FIG. 47.
FIGS. 44 to 46 illustrate a procedure of carrying out another example of a method for generating a memo file illustrated in FIG. 39.
FIG. 44 illustrates a case where if the user makes a long-touch on an image 151X of a particular product from among a plurality of items displayed on a screen, the controller 180 of the mobile terminal 100 selects the image 151X of the particular product. With reference to FIG. 45, it can be known that the image 151X of the particular product has been selected and the selected part is displayed with a dark color.
As shown in FIG. 45, the user touches a soft key 151A for activating a memo function while the image 151A of the particular product is selected. Then, as shown in FIG. 46, the controller 180 converts the image 151X of the particular product into an image and generates a memo file including the converted image 151X′.
FIG. 47 is a flow diagram illustrating a method for generating a memo file according to yet another embodiment of the present invention. In what follows, the method for generating a memo file will be described with reference to related drawings.
The controller 180 of the mobile terminal 100 displays a plurality of items on the screen 151, S300. While the plurality of items is displayed in the screen 151, the controller 180 activates a memo function in response to the user and deactivates a function corresponding to each of the plurality of items S340.
After a memo function is activated, the controller 180 selects a particular area of the screen 151 based on the drag motion of the user against the screen S350. Next, the controller 180 can convert an item included in the particular area into image or text S360 and generate a memo file including the converted image or text.
As described above, whether to convert an item into text and/or image can be determined based on convertibility of the selected item into text and a generated memo file can be stored at least one of storage space associated with a memo application or a clipboard.
FIGS. 48 to 50 illustrate a procedure of carrying out a method for generating a memo file illustrated in FIG. 47.
FIG. 48 illustrates a case where the user touches a soft key 151A for activating a memo function. Then the controller of the mobile terminal 100 activates a memo function and deactivates a function corresponding to each of the plurality of items. Next, the user selects a particular area 151Z displayed on the screen 151 by applying a drag motion. Then the controller 180, as shown in FIG. 48, converts an image 151X of a particular product included in the particular area selected 151Z and the description part 151Y of a particular product into image or text.
Referring to FIG. 49, it can be known that the controller 180 generates a memo file including an image 151X′ converted from the image of a particular product included in the particular area 151Z and text 151Y′ converted from the description part of a particular product included in the particular area 151Z.
Also, referring to FIG. 50, it can be known that the controller 180 can generate a memo file including a capture image 151Z′ for the particular area 151Z.
FIG. 51 is a flow diagram illustrating a method for generating a memo file according to still another embodiment of the present invention. In what follows, the method for generating a memo file will be described with reference to related drawings.
The controller 180 of the mobile terminal 100 displays a plurality of items on a touch screen 151, S300. While the plurality of items are displayed on a touch screen 151, the controller activates a memo function in response to the user's operation and deactivates a particular function corresponding to each of the plurality of items S370.
If handwriting input provided by the user through the touch screen 151 is received after a memo function is activated S380, the controller 180 searches for an item corresponding to the received handwriting input from among the plurality of items and displays the search result on the touch screen 151, S390.
If the user selects for a searched item displayed on the touch screen 151, the controller 180 converts the selected item into a memo file and stores the memo file S395. As described above, whether to convert the selected item into text and/or image can be determined based on convertibility of the selected item into text and a generated memo file can be stored in at least one of storage space associated with a memo application and a clipboard.
FIGS. 52 to 57 illustrate a procedure of searching for an item displayed on a touch screen 151 based on handwriting input received through the touch screen 151 and storing the searched item in the form of a memo file according to a method for generating a memo file illustrated in FIG. 51.
FIG. 52 illustrates a case where the user touches a soft key 151A for activating a memo function. Then the controller 180 of the mobile terminal 100 activates a memo function and deactivates a function corresponding to each of the plurality of items. Next, the user enters handwriting of “stripe” through the touch screen 151 and touches a search soft key 151P.
Then, the controller 180, as shown in FIG. 53, displays a pop-up window 151Q for determining the scope of a search for the contents corresponding to the received handwriting input on the touch screen 151.
Referring to FIG. 53, the object of contents search corresponding to the received handwriting input may be an application running in a current mobile terminal 100, a storage unit 160 of the mobile terminal 100, worldwide web, and the like. However, the scope of the present invention is not limited to the object mentioned above. For example, the item can be searched in other electronic devices including a server of a network to which the mobile terminal 100 is connected, another mobile terminal, personal computers, and the like.
As shown in FIG. 53, the user selects an application running in a current mobile terminal 100 as an object of contents search corresponding to the received handwriting. Then, the controller 180, as shown in FIG. 54, searches for an item corresponding to the received handwriting input of ‘stripe’ from among a plurality of items included in an execution screen of the application and displays the search result on the touch screen 151. In other words, the touch screen 151 shows a searched item 151R including the received handwriting input of ‘stripe’ from the plurality of items.
Different from what is illustrated in FIG. 53, if multiple items are searched, the controller 180 can display the search result for the multiple items on the touch screen 151. At this time, the controller 180, according to an embodiment of the present invention, can collect searched items and display the items on the touch screen 151. FIG. 55 illustrates a case where the user selects an area 151R′ including an item 151R including the received handwriting input of ‘stripe’ by using a multi-touch drag and touches a first soft key 151H1 for generating a memo file. Then, the controller 180, as shown in FIG. 56, displays a pop-up window 151J for selecting a conversion scheme for handwriting input on the touch screen 151. Different from what is illustrated in FIG. 55, the user, after an item is searched, can reduce the area forming the basis for generating a memo file.
FIG. 56 illustrates a case where the user selects an area and uses the selected area 151R′ for storing a memo comprising text and image through the pop-up window 151J. Then, the controller 180, as shown in FIG. 57, can store the selected area 151R′ in the form of a memo file comprising a cushion image 151R′1 and text of ‘yellow stripe’ 151R′2. Though the corresponding examples are not shown in the figure, as described above, whether to convert the item selected through a method for generating a memo file illustrated in FIG. 52 into text and/or image can be determined based on convertibility of the selected item into text; and the generated memo file can be stored in at least one of storage space associated with a memo application and a clipboard.
According to a method for generating a memo file described with reference to FIGS. 52 to 57 above, the item corresponding to received handwriting input can be an item including characters recognized by the received handwriting input. However, the scope of the present invention is not limited to the above description.
According to an embodiment of the present invention, the item corresponding to the received handwriting input can be an item including meaning of a recognized character by the received handwriting input. For example, if a character string ‘pink’ is recognized from the received handwriting input, the controller 180 can search for an item with a ‘pink’ color from among multiple items displayed on a touch screen 151 as an item corresponding to the received handwriting input. Also, if a character string of ‘stripe’ is recognized from the received handwriting input, the controller 180 can search for an item with a ‘stripe’ pattern from among multiple items displayed on a touch screen 151 as an item corresponding to the received handwriting input.
According to another embodiment of the present invention, an item corresponding to the received handwriting input can be searched by a figure recognized from the received handwriting input. For example, if a heart shape is recognized from the received handwriting input, the controller 180 can search for an item with a heart shape as the item corresponding to the received handwriting input.
FIG. 58 is a flow diagram illustrating a method for using handwriting input according to an embodiment of the present invention. In what follows, the method for using handwriting input will be described with reference to related drawings.
The controller 180 of the mobile terminal 100 activates a handwriting input function of a touch screen 151 based on the user's operation S400. If the handwriting input function of the touch screen 151 is activated, the controller 180 can deactivate a particular function corresponding to at least one item displayed in an area intended as a handwriting input area. According to an embodiment of the present invention, the handwriting input area can correspond to the entire touch screen 151 or part of the touch screen 151.
In other words, when a handwriting input function of the touch screen 151 is activated, even if the user touched an item displayed in a handwriting input area of the touch screen 151, the function corresponding to the item touched by the user is not performed. To be more specific, if an execution icon of a particular application is displayed in a handwriting input area of the touch screen 151 and the handwriting input function of the touch screen 151 is activated, the particular application is not performed even when the user touches the execution icon.
At this time, if an item displayed in a handwriting input area of the touch screen 151 is an item included in an execution screen of a particular application, the controller 180 can update the item according to the execution procedure of the particular application. For example, if the running application is a navigation application, the controller 180 can update the execution screen of the navigation application according to the procedure of guiding a path of the navigation application, though a touch function for the execution screen of the navigation application displayed in the handwriting input area may be deactivated.
If the execution screen of the navigation application is not displayed in the handwriting input area of the touch screen 151, the controller 180 may not deactivate the function corresponding to a touch on the execution screen of the navigation application. Then, the user of the mobile terminal 100 can control the execution of the navigation application through a touch motion as well as running a contents search by using handwriting input.
If handwriting input is received through the touch screen 151 after the handwriting input function of the touch screen 151 is activated S410, the controller 180 searches for the contents corresponding to the received handwriting input and displays the search result on the touch screen 151, S420. Here, the contents corresponding to the handwriting input can be searched inside the mobile terminal 100, namely, in the storage unit 160 of the mobile terminal 100. More specifically, the contents corresponding to the handwriting can be searched in the storage unit 160 corresponding to the application currently running in the mobile terminal 100.
Also, the contents corresponding to the handwriting input can be searched in a different electronic device on a network to which the mobile terminal 100 is connected in a wired/wireless manner. In other words, the controller 180 can search a server, another mobile terminal, or a PC on a network to which the mobile terminal 100 is connected in a wired/wireless manner for the contents corresponding to the received handwriting input. For example, the controller 180 can search the worldwide web to which the mobile terminal 100 is connected in a wired/wireless manner for the contents corresponding to the handwriting input.
If the contents corresponding to the received handwriting input have been searched and are displayed on the touch screen 151 and the searched contents are selected by the user's touch motion, the controller 180 displays a control area for carrying out a predetermined function corresponding to the attributes of the search contents S430. Then, the controller 180 performs a predetermined function in accordance to the attributes of the searched contents in response to the touch on the control area S440.
FIGS. 59 to 61 illustrate one example of a procedure through which the contents corresponding to handwriting input are searched according to a method for using handwriting input illustrated in FIG. 58.
