Abstract

Disclosed is a virtual keyboard. When a keyboard for inputting a character is called in a character input space included in an execution screen of an application installed in an electronic device, a virtual keyboard is displayed on an execution screen and text is entered on the virtual keyboard. The virtual keyboard is displayed on at least two edges of an application execution screen.

Description

Virtual keyboard for touch screen {VIRTUAL KEYBOARD FOR TOUCH SCREEN}

The present invention relates to a touch screen. More specifically, it relates to a method of inputting text on a virtual keyboard on a touch screen.

BACKGROUND A touch-sensitive display or touch screen is a well-known technology. BACKGROUND Touchscreens are used in many electronic devices to display graphics and text and to provide a user interface through which a user interacts with the device. The touchscreen detects and responds to a touch on the touchscreen. The electronic device may display one or more soft keys, menus, and other user interface objects on the touch screen. The user may interact with the device by touching the touch screen at a location corresponding to the user interface object to be interacted with.

The present invention provides a more efficient text input method. More specifically, Hangul can be efficiently input using a virtual keyboard displayed on at least two edges.

According to an embodiment of the present invention, a method for inputting text in an electronic device implemented as a computer is provided.

The method includes: displaying a virtual keyboard on the execution screen when a keyboard for inputting characters is called in a character input space included in an execution screen of an application installed in an electronic device; and inputting text into the virtual keyboard. and the virtual keyboard may be displayed on at least two edges of the application execution screen.

According to the present invention, it is possible to input Hangul more efficiently. Specifically, all Hangul characters can be input with 2 or 3 strokes.

In addition, English and Korean or numbers and Korean can be input without changing the keyboard.

In addition, since the virtual keyboard occupies less space, space utilization can be increased, and typing errors can be reduced by providing a more intuitive virtual keyboard.

4 illustrates a smartphone with a pop-up virtual keyboard according to an embodiment of the present invention.
FIG. 5 illustrates an extension of the virtual keyboard according to the embodiment of FIG. 3 .

1 and 2 show the conventionally used virtual keyboards for inputting Hangul. Conventional virtual keyboards commonly pop up from the bottom of the screen, occupying about half of the screen. Accordingly, there is a disadvantage in that the displayed web page or image must be covered. Also, since the keyboard layout is not very intuitive, it is common to make errors in the input process.

3 is a block diagram illustrating an example of components that a processor of an electronic device may include according to an embodiment of the present invention. As components, the processor 212 of the electronic device may include a keyboard display control unit 310 , a search result display control unit 320 , and an input control unit 330 as shown in FIG. 3 . Depending on the embodiment, components of the processor 212 may be selectively included or excluded from the processor 212 . In addition, according to an embodiment, the components of the processor 212 may be separated or combined to express the functions of the processor 212 .

The processor 212 and components of the processor 212 may control the electronic device to provide the virtual keyboard of the present invention. For example, the processor 212 and components of the processor 212 may be implemented to execute instructions according to the code of the operating system included in the memory 211 and the code of at least one program.

Here, the components of the processor 212 are the processor 212 that is executed by the processor 212 according to a command provided by a program code stored in the electronic device (eg, a command provided by a keyboard application driven in the electronic device). may be expressions of different functions of For example, the keyboard display controller 310 may be used as a functional expression of the processor 212 that controls the electronic device according to the above-described command so that the electronic device displays the virtual keyboard on the screen of the electronic device. The processor 212 may read a necessary command from the memory 211 in which the command related to the control of the electronic device is loaded. In this case, the read command may cause the keyboard display controller 310 to display the virtual keyboard on the execution screen of the application calling the virtual keyboard.

4 illustrates a smartphone with a pop-up virtual keyboard according to an embodiment of the present invention. When a text input window appears in the process of surfing a web page or sending and receiving text, a virtual keyboard may pop up on both edges by touching the Korean language selection button. A virtual keyboard for inputting consonants may be displayed on a left edge of the screen, and a virtual keyboard for inputting vowels may be displayed on a right edge of the screen. After the virtual keyboard pops up, text may be input by touching a desired character or by scrolling in a direction indicated by an arrow to select a desired character and then touching.

Hangul is composed as follows.

<Consonants (19)>

a, ㄲ, b, c, ㄸ, d, ㅁ, f, ㅃ, s, ㅆ, ㅇ, ㄱ, tt, ch, ㅋ, t, p, heh (first sound)

<vowel letters (21)>

a, ㅐ, ㅑ, ㅒ, ㅓ, ㅔ, ㅑ, ㅖ, ㅗ, ㅘ, ㅙ, ㅚ, ㅛ, TT, ㅝ, ㅞ, ㅟ, ㅠ, ㅡ, ㅢ, ㅣ (

In addition, there are the following overlapping supports.

<Overlay>

ㄳ, ㄺ, ㄻ, ㄼ, ㄽ, ㅄ

As shown in FIG. 4 , by arranging consonants on the left and vowels on the right in the same order as in actual writing, it is possible to more intuitively grasp the position of a character. In addition, the virtual keyboard occupies less space and does not interfere with a web page or image being displayed on the screen.

FIG. 5 illustrates an extension of the virtual keyboard according to the embodiment of FIG. 4 . By scrolling the left virtual keyboard to the left, the backrest can be displayed. Through this arrangement, the number of inputs (strokes) can be reduced and input errors can be reduced.

For example, when “none” is inputted, the conventional virtual keyboard shown in FIG. 1 performs a total of 11 times (ㅇ+ㅓ+f+o+ㅅ+ㅡ+b+b+l+c+a), as shown in FIG. The conventional virtual keyboard (so-called Cheonjiin) requires input (strokes) of a total of 13 times (ㅇ+. In contrast, if the virtual keyboard of the present invention is used, a total of 10 inputs can be made. In addition, typing can be done quickly with both hands, and typing errors can be reduced.

The arrangement of consonants/vowels is not limited to those shown in FIGS. 4 and 5 . For example, the arrangement of consonants, vowels, double vowels, or diphthongs may be different.

In addition, languages other than Korean may be appropriately combined/transformed.

As described above, although limited embodiments and drawings have been described, a person skilled in the art can make various modifications and variations from the above description. For example, the described techniques are performed in an order different from the described method, and/or the described components of the system, structure, apparatus, circuit, etc. are combined or combined in a different form than the described method, or other components Or substituted or substituted by equivalents may achieve an appropriate result. Therefore, other implementations, other embodiments, and equivalents to the claims are also within the scope of the following claims.

212: processor
310: keyboard display control unit
320: search result display control unit
330: input control
