The present invention is a system for providing a virtual keyboard for a portable electronic device, and more particularly, a keypad for preventing a high typographical problem due to a small keypad itself in a mobile communication terminal having a display screen configured as a touch type and implementing a virtual keyboard in the display screen. A virtual keyboard providing system in which a keypad display is arranged in a space between strings while expanding an area.

The keyboard is an auxiliary device used to input characters from the PC. The keyboard is connected to the PC via a USB cable and provides the function to transmit the character input signal. According to the input method, there are query (qwerty) methods and the like. There are 101 types and 103 types according to the number of keyboards, and mechanical and membrane types are known according to the input method.

Due to the development of touch screen technology, the keyboard is being replaced by a pressure-sensitive and capacitive type. Especially in mobile communication terminals where it is important to reduce the size by emphasizing portability, the keyboard itself is eliminated and a virtual keyboard is implemented on the touch screen. There are many cases.

The virtual keyboard means that the keypad screen is provided within the touch screen and the user inputs the characters assigned to the keypad when the user touches an area assigned to each keypad. The virtual keyboard is also called a touch pad. It is frequently used in touch-type mobile communication terminals that provide a slim and clean image even without the mechanical keypad.

1 is a conceptual diagram illustrating a schematic configuration of a conventional virtual keyboard.

The portable electronic device to which the system according to the present invention is applied is mainly provided with a separate keyboard and input characters and a virtual keyboard only by a touch screen. In other words, a mobile communication terminal such as a smart phone, That is, it consists of a flat type, has a 3 to 5 inch touch display screen at the front and does not have a separate mechanical keypad, and various other portable electronic communication equipment such as game machines, PMPs, MIDs, PDAs. It can be understood as including all things, such as netbooks. That is, in the present invention, the portable electronic device is a generic name for various devices incorporating a keyboard and should not be limited to a specific type of electronic device.

First, prior to describing each configuration according to the present invention, the terms used in the present invention are defined as follows.

The character string means that a plurality of characters input through the virtual keyboard of the present invention form a specific column or row, and mainly refers to displaying a plurality of characters continuously as one line.

That is, in the case of horizontal writing which is generally used, one line of characters, that is, one line becomes a string, and in the case of vertical writing, a character combination consisting of one column becomes a string. In FIG. 3, a plurality of characters consisting of "4 days ... in a currency" forms four strings in a horizontal writing manner.

The character display area refers to a space in which the character string is visually displayed. Referring to FIG. 3, the character display area means a space in which four character strings are displayed.

Such strings generally have a space between the strings, which is also referred to as row spacing or column spacing, which is referred to herein as blank.

A blank is a space that is generally given to the viewer so that the character is too sticky to feel frustrated or unreadable. The present invention provides a feature of displaying a virtual keypad in this blank.

The virtual keyboard is provided as a plurality of keypads on a display screen, in particular, a screen consisting of a touch screen for inputting characters, and the virtual keypad is composed of a plurality of keys provided for inputting respective characters, and a character key is assigned to each keypad. Referring to FIG. 3, it can be seen that the virtual keypad is displayed in blanks, that is, blanks between strings.

The keypad column refers to a plurality of keypads displayed as one line between specific spaces, that is, strings, and may vary depending on Korean characters / special symbols / English, but generally 3 to 5 It consists of four rows.

The keypad area refers to an area that can recognize a character when the keypad responsible for inputting a specific character is pressed. Referring to FIG. 4, an area where each keypad can be recognized is displayed with a line border. Able to know.

A letter key is a visual representation of the input character that each keypad is responsible for. For example, if a particular keypad is responsible for the letter S, the letter key on that keypad is S. In other words, the keypad is S It can be described as having a function for inputting.

The character display area setting module 110 according to the present invention provides a function of setting an area in which a character input by a keypad forms a character string, that is, a user inputs a character through a virtual keypad of the present invention. When the input character is in charge of setting the space to be displayed.

The text display area setting module 110 allows the input text to be displayed with a specific pattern. For example, the text display area setting module 110 guides an area where the input text is continuously displayed, such as horizontal writing and vertical writing. Means that the user can predict it).

Here, the character display area is displayed as 1 line or 2 lines according to the number of strings, but since the virtual keypad according to the present invention has a characteristic of being located between strings, the string is at least 1 more than the number of virtual keypad columns. A large number, that is, n + 1 is made.

The space providing module 120 provides a function of giving a space for displaying a virtual keypad between spaces (character display area) for the character string set by the character display area setting module 110. It is responsible for giving a space formed between strings to provide a smooth recognition.

The blanks provided by the blank grant module 120 may be processed by the vertical and horizontal lengths, that is, the size, by the blank control module 170 to be described later.

The keypad area partition module 130 provides a function of partitioning the entire display screen of the portable electronic device with a plurality of keypads in charge of a character (Korean, English, numbers, special symbols, etc.) to be inputted, and known virtual As shown in FIG. 4, the entire area of the display screen is partitioned according to the keypad number or arrangement as shown in FIG. to provide.

Here, the keypad area partition module 130 is set so that one keypad area necessarily includes a blank (meaning a part of blank space provided in a bar type below a string) provided between strings. In other words, each keypad area is configured to include a part of the character display area and a blank provided at the bottom thereof.

The letter key display module 140 provides a function of displaying a specific letter key that the corresponding keypad is in a position corresponding to a blank of the individual keypad areas set in the keypad area partition module 130.

That is, the character key display module 140 is to play a role of visually displaying each keypad, in particular, a character key that is used for text input by each keypad in a space consisting of 2 to 5 lines provided between character strings.

The character input module 150 provides a function of inputting a character through a virtual keypad. In other words, the character input area 150 allows a user to press a virtual keypad so that a user inputs a value for a character key in charge of the corresponding keypad, that is, a specific character. It provides a premise that allows input characters to be displayed in.

In this case, the character input module 150 includes a cursor function blocking unit 151. That is, the cursor function blocking unit 151 may provide a function of preferentially recognizing a user's touch signal as a virtual keypad input command when the virtual keypad is exposed between character strings by the character key display module 140. In other words, in the case of a keypad provided in a touch screen, when a character touches a string portion displaying an input character when the character is input, the cursor moves to the touch position. This means that the function of moving the cursor is blocked by the cursor function blocking unit 151.

That is, since the keypad area of the present invention overlaps the already displayed character string area (character display area), when a touch occurs in the overlapping area, the function of moving the cursor to the corresponding touch area and the keypad input function collide with each other or overlap each other.

Therefore, in order to prevent such a problem, in the character input situation including the state where the virtual keypad is exposed, only the character input function by touching the virtual keypad is blocked while the other functions including the cursor movement function are blocked in the cursor function blocking unit 151. It is to provide a function to process the active.

In addition, the character input module 150 includes an activation selection unit 152, which moves the cursor to a character that is already entered and displayed in a character string that is already input and needs to be corrected while the character is being input while the virtual keypad is exposed. It is used to move, and has an activation icon on one side of the display screen to provide a function of activating a cursor movement function when clicked.

In other words, if you click on the activation icon and the virtual keypad is exposed, if you touch a specific position where a character string is displayed by prioritizing the cursor movement function over the character input function, the cursor is positioned instead of the character key assigned to that area. It provides the ability to move to.

When the specific location is touched by the activation selection unit 152, the character assigned to the location is input or the cursor is moved to select a function of moving the cursor.

By the above-described basic configuration, the system according to the present invention is arranged so that the character key display indicating whether the keypad is in charge of inputting the character is not so large in the space provided between the strings to separately install the keyboard display area on the display screen. This prevents the keyboard area itself from being reduced, but the keypad area assigned to input specific characters to the corresponding character keys is divided by using the entire display area to expand the area where the keypad can be recognized and to make typing errors. Properties can be provided to significantly reduce the occurrence.

In other words, the keypad area display is implemented by exposing to the spaces between the strings, but the actual keypad area is expanded to use a wider area. In order to overcome the inconvenience, only the character key display indicating which character input the keypad is responsible for is provided in the space provided between the strings to provide the characteristics to fully utilize the display screen space.

Referring back to FIG. 4, it can be seen that the system according to the present invention includes the keypad area display module 160.

The keypad area display module 160 provides a function of visually showing the area occupied by one keypad. In general, the keypad area is displayed only in a space provided between strings, but the actual keypad size is not limited to a blank area level. Because it extends to an area, this wider keypad area is shown to the user, thereby reducing the psychological pressure on the user to press the keypad formed between the strings and providing a factor that allows the user to press the keypad more comfortably.

In detail, the keypad area display module 160 includes a color display unit 161 and a line display unit 162.

The color display unit 161 displays individual keypad areas in different colors. For example, when one of the keypad colors is red, the keypad adjacent to the right is set to orange. To give it color. In this case, in order to prevent the character string from being visually degraded due to the color of the keypad area, that is, the problem of not being easily seen, the color of the keypad area is preferably made of light saturation in pastel tones, and furthermore, it is possible to set the transparency control.

The line display unit 162 displays a line that can be visually visible at the boundary line in the keypad area as shown in FIG. 4, and this line also enables the transparency control setting to prevent the string from being heavily hidden.

The blank adjustment module 170 according to the present invention is to adjust the size of the blank in which the letter key is displayed, and is largely composed of a manual adjustment interface 171 and an automatic adjustment interface 172.

The manual adjustment interface 171 refers to adjusting the size of the blank by the user's selection. In this case, the size of the character key is correspondingly adjusted according to the size of the blank.

That is, of course, the character key area displayed in the blank is smaller than the keypad area. However, when the size of the character key is to be increased in order to provide the user's psychological stability, the space between the strings is increased by touch or numerical adjustment method. Provides a foundation for typing characters more stably.

The automatic adjustment interface 172 automatically adjusts the size of the blank and the character key in consideration of the user's finger thickness, touch tendency, touch position, etc. Specifically, the touch area detector 173 and the area calculator 174, an automatic adjustment unit 175.

The touch area detecting unit 171 provides a specific keypad area to the user to detect a location area that the user generally presses.

At this time, the keypad area is provided with a state where a string is displayed and a state where the string is displayed, respectively, so as to grasp the user's touch tendency when the string is displayed (that is, the degree of psychological pressure felt by the user when the string is displayed). It is possible to do so.

The area calculator 172 calculates a position or an area within the keypad area of the touch area detected by the touch area sensor 171.

That is, to determine whether the user is biased in the upward direction when the user presses a letter key, or whether the touch area is relatively wide. Through this, a touch for inputting a general user's text through a touch position or a touch area is provided. Make sure you understand your disposition.

The automatic control unit 173 automatically blanks and texts according to the propensity of the user to touch a text in a situation such as when the keypad area is given with a text key and a text string through the area calculator 172. Function to adjust the key size.

The blank control module 170 increases or decreases the size of the blank so that the size of the text key can be displayed according to the user's characteristics. For example, when the text key is increased, the input text displayed in the text string becomes smaller and the space between the text strings increases. The character recognition may be a bit uncomfortable, but it may be useful when the character key is reduced by enlarging the character key area, and when the character key is reduced, the opposite characteristic may be provided.

Cursor position adjustment module 180 according to the present invention is because the character keys are displayed between the character strings in accordance with the characteristics of the present invention when the user presses the character key bar is located around the input character, according to the characteristics of the user It is to provide a function of positioning the input position, that is, the position of the cursor near a specific string.

In detail, the cursor position adjusting module 180 includes a cursor position setting unit 181, a cursor position fixing unit 182, and a character string moving unit 183.

The cursor position setting unit 181 provides a function of setting the cursor position according to the user's selection. For example, a user who prefers to position the cursor position at the lowermost string when the string is displayed in multiple lines. Sets the cursor position so that the cursor position is near the bottom of the character string, and a user who prefers to position the cursor position in the middle line of the character string sets the cursor position to that portion.

That is, the cursor position setting unit 181 provides a function of setting a cursor position by receiving a selection from a user by providing a selection window as a cursor position on a separate control window such as the top, middle, and bottom of the character string.

The cursor position fixing unit 182 provides a function of fixing the cursor when inputting a character at the cursor position selected by the cursor position setting unit 182.

The character string moving unit 183 is inevitably executed in conjunction with the cursor position fixing unit 182, and when the cursor position is fixed by the cursor position fixing unit 182, the input character is automatically pushed upward. Provides the ability to be moved.

The cursor position control module 180 provides convenience for selecting and specifying an appropriate cursor position when the user complains of inconvenience, such as hiding an input character when inputting a keypad located between characters.

As described so far, the configuration and operation of the virtual keyboard providing system for a portable electronic device according to the present invention has been expressed in the above description and drawings, but this is merely an example, and the spirit of the present invention is not limited to the above description and the drawings.
