FIG. 2 is a flowchart illustrating a method for processing an input in a portable device according to an embodiment of the present disclosure

Referring to FIG. 2, a controller 130 enters a message creation station state (1100). When a user input for creating a message through an input unit 110 or creation of the message is required according to driving of an application, an application, or a service, the controller 130 enters a message creation state.

The controller 130 can enter a message creation state according to driving an application such as mail transmission, character transmission, memo creation, and diary creation. The controller 130 can control the display unit 150 to display a message creation view according entering the message creation state. Referring to FIG. 3, the message creation view can include an information region 10, an input mode selection region 20, and an input region 30. The information region 10 is a region for displaying information on the message, and can include information on an application providing a message creation function and message information with a message title, and a message number. Further, the information region 10 can include an icon 11 indicating whether a file is attached and an icon for terminating creation of the message or transmitting terminated message. When the message is crated for transmitting a mail or a character, the information region 10 can include information about a transmitter and a receiver. The input mode selection region 20 is a region for receiving selection of the input mode, and can include an icon corresponding to at least one input mode provided for creating the message. In one embodiment of the present disclosure, the input mode selection region 20 can include a text input mode icon 21, a drawing input mode icon 22, an equation or drawing input mode icon 23. The input mode selection region 20 can include an icon capable of setting a message creation mode corresponding to each input mode. For example, the input mode selection region 20 can include a pen attribute selection icon, an eraser attribute selection icon, an image addition icon, and a file attaching icon.

The input region 30 is a region capable of receiving a user input, and can display contents of the created message simultaneously with input of the contents of the message. Next, the controller 130 determines whether an input is detected (1200).

If the user input is generated, the input unit 110 generates an input signal including input location information and transfers the input signal to the controller 130. The controller 130 can determine whether an input is detected according to whether an input signal is received from the input unit 110.

If the input is detected, the controller 130 determines whether the input is detected at an input region (1300).

The controller 130 determines whether an input is detected and a detected position of the input based on the input signal received from the input unit 110. The controller 130 can determine whether the input is detected on the message creation view and at which region of the message creation view the input is detected based on the determination result.

If the input is detected at the input region, the controller 130 determines an input mode (1400).

The controller 130 can determine an input mode based on the input mode setting state according to the user input, an input mode state set upon creation of a final message or an input mode setting state due to a default value. The controller 130 can receive selection of an input mode from the user through the input mode setting region 20. A method of setting an input mode by the user will be described later. According to one embodiment of the present disclosure, the input mode can include at least one of a text input, a drawing input, an equation input, and a drawing input.

Next, the controller 130 processes an input according to the input mode to create the message (1500). The controller 130 processes text, image, equation, or drawing corresponding to an input according to the input mode to create the message. Hereinafter, the following is a detailed embodiment which processes an input according to each input to create the message.

First Embodiment

Text Input Mode

If the input mode is a text input mode, the controller 130 processes text corresponding to the input to create a message.

In detail, referring to FIG. 4, the controller 130 determines whether the input mode is the text input mode (1511). If the input mode is the text input mode, the controller 130 can display a key pad (1512).

As shown in FIG. 5, the controller 130 can control the display unit 150 to display a key pad 40 for providing a text interface. The key pad 40 can be configured by at least one character, numeral, special symbol. The key pad 40 can be stored in the memory 140, can be stored upon manufacture of the portable device 100 or can be downloaded from a server. The key pad 40 can be configured by a format such as chunjiin or qwerty by a manufacturer or a provider of the key pad 40.

The controller 130 can control the display unit 150 to display the key pad 40 by applying a slide effect and an animation effect. For example, the controller 130 can display the key pad 40 by applying a slide effect slidably lifting upward. Next, the controller 130 can determine whether an input through the key pad is detected (1513). If the input signal is received from the input unit 110, the controller 130 can determine whether an input is detected through the key pad 40 based on an input signal. If the input through the key pad is detected, the controller 130 can process text corresponding to the input (1514).

The controller 130 can determine a text corresponding to the input. The controller 130 can determine a location in which the input is generated based on the input signal to extract a text corresponding to the input location. If the text corresponding to the input location is extracted, the controller 130 can process the input detected through the key pad 40 as a text corresponding to the input. For example, when the input is detected on the key pad 40 of FIG. 5 and a text corresponding to the input location is ‘H’, the controller 130 can process the input ‘H’.

After that, the controller 130 can insert the processed text into the message (1515).

The controller 130 can insert the processed text into the message to create the message. In this case, the controller 130 can control the display unit 150 to display the created message on the input region 30. For example, if the processed text is an ‘H’, the controller 130 can insert the ‘H’ into the message to create the message, and display the ‘H’ on the input region 30. The controller 130 can arrange and insert the text suited to the size and the format of the input region 30. The controller 130 can process a text corresponding to the input to create the message while the input through the key pad 40 is repeatedly detected. Referring to FIG. 5, the controller 130 can process the repeated detected input as the text to create a message as text input contents 31 with “Happy birth day”.

While the message is created in the text input mode, when an input of changing the input mode is detected or the input is detected at a region other than the key pad 40, the controller 130 can control the display unit 150 to hide the display key pad. In this case, the controller 130 can control the display unit 150 to hide the key pad 40 by applying a slide effect and an animation effect. For example, if the input is detected at the input region 30 other than the key pad 40, the controller 130 can hide the key pad 40 by applying a slide effect slidably downing to a bottom of the view and disappearing.

While the message is created in the text input mode, when an input changing the input mode or when the input is detected at a region other than the key pad 40, the controller 130 can control the display unit 150 to scroll a message including text input contents 31 in a predetermined direction. The controller 130 can hide some of created input contents by scrolling the message in a predetermined direction, thereby enlarging a blank for creating an additional message in the input region 30.

Second Embodiment

Drawing Input Mode

If the input mode is a drawing input mode, the controller 130 process an input as an image to create a message. In detail, referring to FIG. 6, the controller 130 determines whether the input mode is a drawing input mode (1521). If the input mode is the drawing input mode, the controller 130 can display an input window for drawing input (1522).

As shown in FIG. 7, the controller 130 can control the display unit 150 to display an input window 50 for providing a region to which drawing can be input.

The input window 50 can include an edge line for setting a region to which the drawing can be input. The input window 50 can include an icon capable of terminating a drawing mode.

In one embodiment of the present disclosure, the input window 50 can have a fixed size and form. The input window 50 can have a fixed size and form which are not changed according to a display direction of a view. For example, referring to FIG. 7, an input window 50 when the portable device 100 displays a view in a portrait mode and an input window when the portable device 100 displays the view in a landscape mode can have the same size and form. In this case, a view display direction is switched in a state that the input window 50 is fixed, a blank 90 displayed on the display unit 150 of the portable device 100 can be processed as a dead space.

Next, the controller 130 can process an input detected through a drawing input window as an image (1523). As shown in FIG. 7, the controller 130 can detect a drawing input 51 through the input window 50, and generate an image configured by input tracks of the detected drawing input 51.

The controller 130 can generate an image with respect to the entire region of the input window 50. In one embodiment of the present disclosure, the controller 130 can generate an image except for a blank region in which an input with the entire region of the input window 50 is not detected. For example, referring to FIG. 7, the controller 130 can detect the drawing input 51 through the input window 50. Further, the controller 130 can generate an image based on a region in which the drawing input 51 is detected except for a blank region among the entire region of the input window 50. The blank region can be excluded in the step of inserting a message. That is, the controller 130 can generate an image with respect to the entire region of the input window 50, and remove the blank region in which an input is not detected from the entire region of the image. As shown in FIG. 8, a message including drawing input contents 32 can be created by inserting an image from which the blank is removed in the message.

The controller 130 can temporarily or permanently store the generated image in the memory 140. The controller 130 can store the generated image associated with the message, and can store a drawing order of the image, information on a drawing track, and an attribute of an applied drawing pen during drawing. Information of an image stored in the memory 140 can be used to edit the generated image.

Next, the controller 130 can insert the generated image into the message (1524). The controller 130 can insert the processed image into the message to create the message. In this case, the controller 130 can control the display unit 150 to display the created message on an input region 30. The controller 130 can arrange and insert the image suited to the size and a format of the input region 30. The controller 130 can attach the generated image to the message as a file, and accordingly display an icon indicating that the file is attached to the message.

In one embodiment of the present disclosure, while creating the message in a drawing input mode, when an input changing an input mode is detected, an input of an icon for terminating a drawing input mode is detected, or the input is detected at a region other than the input window 50, the controller 130 can insert the generated image in the message.

While creating the message in a drawing input mode, when an input changing an input mode is detected or the input is detected at a region other than the input window 50, the controller 130 can control the display unit 150 to scroll a message with drawing input contents in a predetermined direction. The controller 130 hides some of input contents in an input region by scrolling the message in a predetermined direction, thereby enlarging a blank for creating an additional message in the input region 30.

Third Embodiment

Equation/Drawing Input Mode

If the input mode is an equation or drawing input mode, the controller 130 processes the input as an equation or a drawing to process the message. In detail, the controller 130 determines whether the input mode is an equation or drawing input mode (1531).

In one embodiment of the present disclosure, when the input mode is the equation or drawing input mode or selection for the equation or drawing input mode is detected, the controller 130 can display a menu capable of selecting one of an equation and a drawing (1532).

For example, referring to FIG. 10, the controller 130 can detect selection for the equation or drawing input mode through an equation or drawing input mode icon 23. Accordingly, the controller 130 can display a menu 24 capable of selecting one from the equation input mode and the drawing input mode.

If an input selecting one from the equation and the drawing is detected through the menu 24, the controller 130 can perform an operation corresponding to one of the equation input mode and the drawing input mode.

Next, the controller 130 can display an equation or drawing input window (1533). The controller 130 can control the display unit 150 to display the equation input window or the drawing input window in response to selection of the equation or drawing input mode.

As shown in FIG. 11 or 12, the, controller 130 can control the display unit 150 to display an equation input window or a drawing input window for providing a region capable of an equation or a drawing. The equation input window and the drawing input window can include a result display region 61 displaying a result in which an input is processed and an equation input region 62 capable of inputting the equation.

After that, the controller 130 can process an input detected through the equation or drawing input window as the equation or the drawing (1534).

As shown in FIG. 11, the controller 130 can detect an equation input 63 through an equation input region 62 of the equation input window, and can search a character corresponding to the detected equation input 63. For example, if an input “x” is detected through the equation input region 62, the controller 130 can search a character corresponding to the input. The controller 130 can analyze a track and a form of the input “x”, search a character corresponding thereto, and determine “x” as a character corresponding to the input. The controller 130 can process the input as a searched character according to a search result. The controller 130 can display equation input contents 64 configured by processed characters on a result display region 61.

Further, as shown in FIG. 12, the controller 130 can detect a drawing input 65 through a drawing input region 62 of a drawing input window, and search an image corresponding to the detected drawing input 65. The controller 130 can analyze a track and a form of an input to search a corresponding image from an image database. The image database is configured by the user or a manufacturer of the portable device 100, and can include at least one image corresponding to a predetermined input.

The controller 130 can process the input as a searched image according to the search result. The controller 130 can display drawing input contents 66 according to the processed image on a result display region 61.

The controller 130 can temporarily or permanently store the processed equation or drawing in the memory 140. The controller 130 can store the processed equation or drawing associated with the message, and information on an input order. Information stored in the memory 140 can be used to edit the equation or the drawing.

Next, the controller 130 can insert the processed equation or drawing into the message (1535). The controller 130 can insert the processed equation or drawing into the message to create the message. In this case, the controller 130 can control the display unit 150 to display the created message on the input region 30. The controller 130 can arrange and insert the equation or the drawing suited to the size and a format of the input region 30.

The message created according to one embodiment of the present disclosure includes at least one input content processed in at least one input mode. Referring to FIG. 13, the message can include at least one of text input contents 31 processed in a text input mode, drawing input contents 32 in a drawing input mode, and equation/drawing input contents 33 processed in the equation/drawing input mode.

When the input is not detected on the input region, the controller 130 determines whether the input is detected in the input mode selection region (1600).

The controller 130 determines whether the input is detected and a detected position of the input based on an input signal received from the input unit 110. The controller 130 can determines whether the input is detected in a message creation view and at which region of the message creation view the input is detected. The controller 130 determines whether the input is detected in an input mode selection region 20 of the message creation view.

When the input is detected in the input mode selection region, the controller 130 sets an input mode according to the input (1700).

The controller 130 determines an input mode corresponding to the detected position of the input to set the input mode. For example, if an input with respect to a text input mode icon 21 is detected on the input mode selection region 20 of FIG. 3, the controller 130 can set the input mode as a text input mode, and perform an operation for processing a text input.

When the input is not detected on the input mode selection region, the controller 130 can perform an operation corresponding to the input (1800).

The controller 130 can determine whether a storage or transmission request occurs (1910). The controller 130 can determine whether a storage or transmission request of the message created according to the user input occurs.

If the storage or transmission request occurs, the controller 130 generates and stores or transmits message data to other portable devices (1920).

If the message storage request occurs, the controller 130 stores the message in the memory 140. In this case, the controller 130 can store meta data including information on at least one input mode with respect to input contents of a message associated with the message.

If the message transmission request occurs, the controller 130 can control the communication unit 110 to transmit the message to another portable device. In this case, the controller 130 can transmit meta data associated with the message together with the message to another portable device. The another portable device having simultaneously receiving the meta data and the message can edit the message according to the same input mode as that of the portable device transmitting the message using the meta data.

FIG. 14 is a flowchart illustrating a method for editing a message according to an embodiment of the present disclosure.

Referring to FIG. 14, the controller 130 determines whether input contents of the message are selected (2100). The controller 130 can control the display unit 150 to display the message including the input contents processed in the at least one input mode. Further, if an input signal is received from the input unit 110 so that an input is detected, the controller 130 determines whether the input is an input selecting input contents included in the message based on the input signal. For example, referring to FIG. 15, the controller 130 can detect an input for selecting drawing input contents from the input contents of the message.

If the input selecting the message input contents is detected, the controller 130 determines an input mode corresponding to the input contents (2200).

The controller 130 determines an input mode in which input contents are created based on meta data stored associated with the message. For example, as shown in FIG. 5, if the drawing input contents 32 are selected, the controller 130 can determine the drawing input mode as an input mode corresponding to the drawing input contents 32 based on the meta data stored associated with the drawing input contents 32.

Next, the controller 130 performs an operation for editing input contents corresponding to the input mode (2300).

The controller 130 can control the display unit 150 to display an edit view corresponding to the input mode in order to edit the input contents. The controller 130 can display input contents on the edit view and edit the input contents according to the user input. The controller 130 can remove or correct the input contents in an input order according to meta data associated with the input contents.

For example, as shown in. FIG. 15, if the drawing input contents 32 are selected, the controller 130 can process an edit input of the user as an image according to the drawing input mode.

The method for processing an input in a portable device and a portable device thereof according to the present disclosure can create contents corresponding to various input modes as one message without view switch according to an input mode during creation of the message.

The method for processing an input in a portable device and a portable device thereof according to the present disclosure allow a user to input contents according to various input modes while confirming created message contents to easily create and edit the message.

Although the present disclosure has been described with an embodiment, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
