{A KEYBOARD FOR REDUCING THE TOUCH / CLICK ERROR IN SMALL ELECTRONIC APPARATUS}

The present invention relates to a keyboard of a small electronic apparatus requiring a keyboard input such as a smart phone or the like.

In most office automation devices such as PCs, the input method of letters is QWERTY (or keyboard, hereinafter) for English characters, and it is a double-edited keyboard for Hangul. Since the English alphabets and Korean alphabets correspond to the same keyboard, they are described as a QWERTY keyboard.

As small electronic devices such as mobile phones have developed, various keyboard input methods have been developed for these devices. In the feature phone that is operated by pressing the mechanical button at the beginning, there was only a simple numerical keypad for simple input such as a telephone number. However, since the necessary functions such as inputting the name of the telephone book, transmission of a short message (text) . However, due to the characteristics of small devices, it is not possible to apply QWERTY keyboard. Therefore, various input methods unique to Hangul keyboard such as Cheonjiyin were developed. They have developed a algorithm that uses a limited number of keyboards and combines them, and has many advantages. However, there are some disadvantages that only one letter is required to be pressed several times. Hereinafter, these are referred to as a combination keyboard for the sake of convenience.

Since then, the number of letters input has been frequently used for functions such as long message transmission, e-mail transmission, SNS (social networking service) such as Twitter, and QWERTY keyboard is also used, Each has advantages and disadvantages and is currently used in coexistence.

The QWERTY keyboard is convenient for users who are familiar with automation devices such as PCs, but there are various inconveniences due to the arrangement of a large number of keyboards in a limited area in a miniaturized device such as a mobile phone. It is inconvenient to input and an area occupied by one keyboard is small, so that an error that a surrounding character is inputted rather than a character input (touch or click) frequently occurs.

The present invention is conceived to solve the above-mentioned problem of keyboard input error, and it is an object of the present invention to provide a keyboard layout capable of minimizing an input error while making use of a convenient function of a QWERTY keyboard in a small electronic apparatus such as a mobile phone, A method for inputting a keyboard is provided.

In order to achieve the above-mentioned object, in the present invention, it is possible to input a keyboard easily by enlarging the area occupied by one keyboard by reducing the number of horizontal arrangements of the keyboard and increasing the number of vertical arrangements.

According to the keyboard layout method disclosed in the present invention, when a miniaturized electronic device such as a mobile phone is used, it is possible to input Korean or English characters in a manner familiar to an office automation device such as a PC, There is an advantage that the user can quickly input letters.

Hereinafter, a processing procedure and an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiments of the present invention described below can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to enable those skilled in the art to more fully understand the present invention.

Most small electronic devices such as mobile phones have a rectangular shape with a different length and width. There are two behaviors that use this mode: landscape mode and portrait mode. FIG. 1 is an example of a landscape mode. In this mode, a QWERTY keyboard can be used relatively easily. 10 is a character display area and 11 is a keyboard display area. 2 is an example of a portrait mode, where 20 is a character display area and 21 is a keyboard display area. 1 and FIG. 2, it can be seen that the width of one keyboard is relatively large in the landscape mode, but the width of the screen is extremely reduced in the portrait mode. On the other hand, in the landscape mode, the height of the display area 10 becomes smaller than the height of the display area 20 of the vertical mode.

In terms of the usage patterns of electronic devices, landscape mode is mainly used in applications that do not use a keyboard such as a picture, a picture, a video display, a game, and the like, and a lot of characters such as a message writing, a memo writing, The application mainly uses portrait mode. That is, the basic mode of the portable device is the portrait mode. Therefore, there is a considerable inconvenience in using the vertical mode and switching to the landscape mode in order to use a large QWERTY keyboard.

Recently, portable electronic devices such as mobile phones have been increasing in size, but the proposition of portable devices that they should be easy to use in one hand has a limitation in enlargement. And the original QWERTY keyboard optimized for the position of the left and right fingers can not be realized in small handheld devices. Therefore, the present invention is advantageous in that it is possible to easily input a part of fingers (mainly a thumb) of the left and right without typing.

Figure 3 shows the entire configuration using one of the keyboard layouts disclosed in the present invention. 30 is a character display area, and 31 is a keyboard display area. The detailed arrangement of the keyboard will be described later. As the height of the keyboard display area 31 of the disclosed invention increases, the height of the display area 30 becomes smaller than the height of the display area 20 of the portrait mode of FIG. However, the height does not decrease more than the height of the display area 10 in the landscape mode of Fig. 1, and there is no practical problem. Although the present invention is characterized in the vertical mode, it is applicable not only to the vertical mode but also to the horizontal mode.

4 to 8 are representative examples of the keyboard layout disclosed in the present invention. The present invention is not limited to this example and includes similar arrangements that follow the following description.

The QWERTY keyboard of the portable device places ten keyboards in the width direction, usually due to space constraints (Figs. 1 and 2). The keyboard layout disclosed in the present invention divides an arrangement of one row of conventional QWERTY keyboard into two rows of arrangements 43 and 44 as shown in FIG. 4A. A feature of the present invention is here and thus increases the lateral size of the individual keyboards. The number of individual keyboards in one line is six in the example of FIG. 4, but is not limited thereto. The total number of lines in the vertical direction increases to seven lines in four lines (Figs. 1 and 2), so that the vertical length (height) occupied by the keyboard increases (31) and the height of the display area decreases (30).

There are two ways to rearrange the original QWERTY keyboard into 2 lines: 5 - 5 keyboard layouts for the first and second lines (5-5 layouts), 6 layouts: 4 layouts (6-4 layouts), 4 There are many ways to do this: six (four to six). In the present specification, not all of them are enumerated, they are all included in the present invention. 4A shows an embodiment of a 6-4 arrangement. Instead of dividing one line of the existing QWERTY keyboard into halves, you can use two left-handed keyboards on the left (position 40) (three positions 43) and two keys left (position 40) And the right-handed key board is placed on the right side (the position of 42), three on the top, and two on the bottom.

The area 41 in FIG. 4A serves to increase the convenience of using the left hand and right hand simultaneously by slightly opening the gap between the left (position 40) keyboard and the right (position 42) keyboard. 45 means shift, and 46 means backspace. When the shift key 45 is input in the keypad of FIG. 4A, the keypad of FIG. 4B is switched. The keyboard of FIG. 4B corresponds to a corresponding position of a conventional QWERTY keyboard in which a phoneme and a phonetic keyboard are disposed. The keyboard of FIG.

Fig. 5 shows various modified embodiments of the 6-4 arrangement and the 4-6 arrangement, wherein Figs. 5A to 5D show the 6-4 arrangement and Figs. 5E to 5I show the 4-6 arrangement. 6 shows an embodiment of the 5-5 arrangement. 6A and 6B are similar to the 6-4 arrangement in which consonants are arranged on the right side of the vowels on the left side, but the positions of the boundaries (60 and 61 in FIG. 6A) do not coincide. The 5-5 arrays are more advantageous in prevention of typos because they can increase the width of the individual keyboards as the number of vertical lines is equal to 7 lines as compared with 6-4 arrays. In the arrangement of FIG. 6C, five keyboards on the left side of the existing QWERTY keyboard are arranged on the first line, and five keyboards on the right side are arranged on the next line.

From the viewpoint of a user who is accustomed to using a conventional QWERTY keyboard, the arrangement of FIG. 4 is advantageous among the various methods of FIGS. 4 and 5. In FIG. 4A, the keyboards 'C', 'A', 'K' and 'K' are reversed relative to the horizontal position of the existing keyboard, but they are located close to each other. have.

The conventional QWERTY keyboard can be a little awkward when it is divided into two lines by one line, but when it is mastered, convenient and efficient input is possible, and the user who is familiar with the existing QWERTY keyboard is more advantageous. First of all, the big advantage is that the area occupied by each keyboard becomes larger, so that the probability of typos is greatly reduced and the sentence can be effectively generated.

In FIG. 7, an alphabetic character layout of an English QWERTY keyboard is arranged at a corresponding position in the same manner as in FIG. When the shift 70 is inputted in the English lower-case letter key plate of FIG. 7A, it is converted to the English upper-case letter key plate of FIG. 7B.

FIG. 8 shows the keyboard arrangement of numbers and various symbols. When the shift 80 is input from the keyboard of FIG. 8A, the keyboard is switched to the keyboard of FIG. 8B. The assignment of letters to each keyboard of numbers and symbols can be varied, so it is not limited to the example of FIG. Since the code input is not frequent, in the example of FIG. 8, more characters can be input even in a vacant space for the convenience of inputting in the Korean or English character keyboard of FIG. 4 or FIG.

Although an English keyboard and a Hangul keyboard have been disclosed as embodiments of the present invention, it is also included in the present invention to use a keyboard layout similar to the present invention for other languages.

The keyboard layout according to an embodiment of the present invention as shown in FIGS. 4 to 8 is a touch screen type electronic apparatus in which a keyboard layout is implemented on a screen, and a keyboard layout in which individual keyboard layouts are mechanically protruded or planar, The present invention is similarly applied to a keyboard operating as a keyboard.

While the present invention has been described with reference to specific embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover many modifications and equivalent arrangements included within the spirit and scope of the appended claims, It is possible to carry out the modification by branching, and this also belongs to the present invention.
