Description

Arrangement Structure and Character Input Method for One-hand Keyboard of Smartphone}

The present invention relates to an arrangement structure and a character input method of a smart phone keyboard that can be input with one hand thumb, and arranges the keyboards in an arc shape that is a shape of a thumb movement radius, and the configured keyboards are grouped and grouped based on characters in common. Thus, the first click selects and enters the grouped character folder, and the second click selects the character to be input from among the rearranged characters in the character folder, so that character input is performed through a relatively small number of keys. The present invention relates to a keyboard layout structure and a text input method that enables and reduces typos and fatigue when inputting text with one hand.

After the use of smartphones has been generalized, the screens of smartphones have been gradually increasing due to technological development and consumer demand. Due to this, the size of the device becomes uncomfortable for holding and writing with one hand. In general, the one-handed mode pushes the keyboard to the right or left to reduce the size of the keyboard so that it can be entered with one hand, but the size of the keys to be pressed is too small and the number of keys placed is frequent, resulting in frequent typos. In contrast, the thumb used for input has a circular line in a circular arc shape, whereas the arrangement of the keyboard is rectangular, so the one-handed mode is only an arbitrary device due to the inconvenience caused by this.

Conventional keyboards, which are traditionally Cheonji, have the advantage of being able to intuitively input vowels, so that characters can be input without going through a complicated understanding process, but there are disadvantages in that the number of clicks required to enter one vowel can be increased. For example, in order to write 'ㅙ', the number of clicks required for the qwery keyboard is 2, whereas the keyboard for heaven and earth must be pressed 5.

Korean Registered Patent No. 10-1851272 (registered on April 17, 2018; hereinafter referred to as 'Prior Art 1') presented a one-handed keyboard based on a smartphone. In the prior art document 1, the consonant input area and the vowel input area are separated within a range in which a thumb can reach the screen, and priorities are set according to the frequency of input. By reducing the user's fatigue, instead of giving the user an intuitive understanding of the character arrangement, it is difficult to learn the character arrangement from the beginning. In addition, the area where the finger is moved to input a character is limited by placing a letter in the area of the thumb, but in order to select a letter, one of the letters arranged in multiple rows is frequently folded or unfolded within the area of the thumb. There is a hassle to choose from, and the weakness of focusing on the thumb is inherent.

Korean Registered Patent No. 10-1169849 (registered on July 24, 2012; hereinafter referred to as 'Preceding Document 2') proposed a character display method. In the preceding document 2, in a character display method in which a character composed of consonants and vowels is arranged on a circumferential column divided at a predetermined interval, and a character indicated by a leader line drawn in a circumferential direction is selected from the center of the circumference, the character is determined according to the direction The characters were input according to the movement of the finger contact area to be placed and slided. However, since detailed movement is required in operation, a lot of effort is required until an unfamiliar user can naturally input text. In addition, although the number of clicks can be reduced in text input, the finger movement direction is from the center to the circumferential direction. Since the entire target is used, in the one-handed input method in which the input is performed while the hand is fixed, the movement of the finger is limited, and thus there is a difficulty in character input.

Accordingly, there is a need for a new type of keyboard arrangement that provides a one-handed text input method but minimizes thumb fatigue in the text input process.

Korean Registered Patent No. 10-1851272 (Registration on April 17, 2018): One-hand keyboard based on smartphone Korean Registered Patent No. 10-1169849 (Registration on July 24, 2012): Character display method

1 to 4, the one-handed keyboard arrangement structure according to an embodiment of the present invention,

In the one-key keyboard arrangement structure that appears on the screen of the smartphone 1 when inputting text, a group of characters classified into each divided region by being arranged along a path in which the tip of the thumb of the hand holding the smartphone is moved and divided into conformal multiples An arc type character input keypad (10) in which a folder is displayed or characters included in the selected group folder are arranged to be input by character selection; An enter key pad 20 disposed at a center of a call, which is an inner area of the arc character input keypad; Vertical function selection keypad 30, which is formed vertically on one side of the arc character input keypad and the enter key pad and is vertically divided to place special character / number transformation, Korean-English transformation, case transformation, space and backspace selection keys ; It is configured to include.

The arc-shaped character input keypad 10 is a keypad formed along a moving line where the thumb moves without bending when the user holds the smartphone with one hand and inputs it with the thumb.

The arc-shaped character input keypad 10 has a fan shape formed at an angle of 90 degrees, and the horizontal surface and the vertical surface of the bottom surface are disposed on the bottom and left sides or the right side of the smartphone screen. The left or right arrangement of the arc-shaped character input keypad may be determined and displayed according to the touch position when the smartphone screen is first touched.

The arc-shaped character input keypad 10 is formed to be elongated along the line of the thumb, and is divided into a number of equal parts to display characters on the divided regions 11 to make selection. The division may be made as many as necessary, and when using a group folder as in the present invention, if the group folder is 5, it is divided into 5, and if the group folder is 6, it can be divided into 6 and provided.

In addition, after the group folder is selected, the arc type character input keypad is divided at equal intervals by the number of characters classified in the group folder, and the characters are arranged in each divided area.

In the arrangement of the keyboard, the size of the fan-shaped arc-shaped character input keypad is within a range not exceeding the movement of the thumb. In addition, the main feature of the present invention is that the arrangement of the keyboard is in the form of a fan so as not to deviate from the range in which the thumb moves. Includes variants.

For example, assuming that the fan is placed on the right screen, the area required for character input is placed along the edge of the fan, and the vertical bar is placed on the right or left for the functions for enter, space, hanyoung, and backspace. By forming the vertical function selection keypad in the form, it forms a shape that does not deviate from the fan shape as shown in FIG. 1.

In the keyboard layout of the present invention, unlike the existing keyboard layout that occupies the entire lower portion of the screen, it occupies a limited space for drawing a fan on the right or left side. There are many typos. In order to prevent this, it is necessary to increase the size of the key by reducing the number of keys. In the first selection, the group folder in which the characters are classified is selected by dividing the process in one character input into two selections. The characters contained within are rearranged on the keyboard, and by selecting the character to be input from among the characters in the group folder in the second selection, the number of keys required for character input can be reduced.

This is the same way, for example, in order to find a file in the computer's file explorer, first select the folder containing the file and then find the file in it again.

In the text input that requires two selections, slides are made to select, but the slide is made by touching, pushing, and releasing the thumb on the smartphone screen. Here, on the keyboard of the screen that has not been touched, a group folder containing characters is divided and arranged in the area of the arc character input keypad, and first, it touches the text area arranged at the edge of the fan, and the characters in this folder are displayed. To relocate, push to evenly relocate the characters, and release to determine the character to be finally entered.

The arc-shaped character input keypad 10 is formed along the outer side of the arc in the form of a fan, and on the inside, it is possible to select and provide one to three keypads frequently used for character input, including the enter-key pad 20. have. In addition, on one side of the fan bone shape, a vertical function selection keypad 30 in the form of a rod is arranged in a vertical direction that is vertical. The vertical function selection keypad is a space, backspace, Korean-English conversion, special alphanumeric conversion functional keypad is arranged, the arrangement order can be variously combined.

In addition, the character classification for grouping characters has a close relationship with the number of divisions of the arc-type character input keypad. In the embodiment of the present invention, only six are described. That is, the characters are classified into six groups, and six characters are arranged in each group.

The classification of Hangul is based on the similarity of the shape as the main criterion, so that the user can easily recognize it. The standard of classification is the shape of a letter, and the location and method of sounding are parallel. In Korean, there are 19 consonants and 10 vowels. Consonants are ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ, ㅊ, ㅋ, ㅌ, ㅍ, ㅎ, ㄲ, ㄸ, ㅃ, ㅆ, 모음, vowels are ㅏ, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ, ㅡ, ㅣ. At this time, 구성, ㄸ, ㅃ, ㅆ, ㅉ in the composition of consonants, that is, although the old sound can make 'ㄲ' twice as 'a', the reason why it is included in the configuration is the place to place characters in the composition of the key This is because the number of inputs required for character input increases as much as inputting the sound with two inputs without arranging the sound.

The consonants are classified as 'ㄱ' (ㄱ, ㄲ, ㅋ, ㅇ, ㅎ), 'b' (ㄴ, ㄷ, ㄸ, ㅌ, ㄹ), 'ㅁ' (ㅁ, ㅂ, ㅃ, ㅍ), 'ㅅ' (ㅅ, ㅆ, ㅈ, ㅉ, ㅊ) four. The reasons for this classification are as follows.

If the consonants are classified according to the location and method of sounding, consonants are divided into distinctive sounds such as' ㄱ ',' ㄲ ', and' ㅋ '. These are divided into' A, 된, ㅋ ',' c, respectively. Five distinctions are made, including 'ㅅ', with no harsh sounds such as, ㄸ, ㅌ ',' ㅂ, ㅃ, ㅍ ',' ㅅ, ㅆ, ', and' ㅈ, ㅉ, ㅊ ', classified here 'B, ㅁ, ㅇ, ㄹ, ㅎ', which is not possible, is distinguished because it is different from the above.

Consonants are divided into six categories if the above classification is used, but the configuration of the present invention requires reduction of this in order to arrange vowels because six letter keys have been used. So, the composition of 'ㅅ' and 'ㅈ' with similar shapes are merged into one, and 'b, ㅁ, ㅇ, ㄹ, ㅎ' is spread out and included in each category based on each sounding position. 'ㅇ' is included in 'ㄱ' because the sounding location is the same, and 'ㅎ' is included in 'ㅇ' because it is easy for users to recall. 'B, ㄹ' is included in 'c', where the sound location and the shape of the letter are similar, and 'ㅁ' is included in 'ㅂ' for the same reason. As a result, four classifications are created, and among them, the fastest consonants are selected in order of ㄱㄴㄷ, 'ㄱ' (ㄱ, ㄲ, ㅋ, ㅇ, ㅎ), 'ㄴ' (ㄴ, ㄷ, ㄸ, ㅌ, ㄹ ), 'ㅁ' (ㅁ, ㅂ, ㅃ, ㅍ), and 'ㅅ' (ㅅ, ㅆ, ㅈ, ㅉ, ㅊ).

The classification of vowels is divided into whether or not semi-vowels are included. At this time, the semi-vowel refers to the 'ㅣ' pronunciation that comes from the difference in pronunciation between 'ㅏ' and 'ㅑ', and is the concept of viewing 'ㅑ' as 'ㅣ' + 'ㅏ'. Based on this, it can be classified into two types: ㅏ '(ㅏ, ㅓ, ㅗ, ㅜ, ㅡ, ㅣ), and' ㅑ '(ㅑ, ㅕ, ㅛ, ㅠ). Since one stroke is added, it is easy to recognize the difference.

The classification of English is based on the order of ABC, but it is necessary to divide the characters into equal numbers in 26 alphabets and find a common point between each classified character. 'a' (a, b, c, d, e, f), 'g' (g, h, i, j, k), 'l' (l, m, n, o, p), 'q' (q, r, s, t, u), divided by 'v' (v, w, x, y, z). The criteria here are used when we write ABC, or when we write the alphabet normally. It is based on that. The reason why 'a' is grouped from a to f is that alphabets from 'a' to 'f' are mainly used for scoring in everyday life, so they are generally classified together and there is no sense of incongruity. It is classified, but each 'I, j', 'l, m, n', 'v, w', 'x, y, z' is written together in everyday life or written as an alphabet, and it is called as a single beat. There is a part where you can feel the sex, so there is no difficulty in dividing it into 5 pieces.

A method for inputting a text using the one-handed keyboard layout structure of the smart phone will be described.

First, a one-hand keyboard activation step is performed by touching a screen of a smartphone to display an arc type character input keypad, an enter key pad, and a vertical function selection key pad so that character input is performed. In this step, if a part requiring text input on a smartphone, for example, a message or SNS, is required for text input, each keypad is activated to be displayed on the smartphone screen.

At the same time, a step of displaying a group folder is performed by arranging a group folder grouped by classifying a plurality of characters in each divided area of the arc character input keypad.

Subsequently, a step of selecting any one of the plurality of group folders displayed on the smartphone screen is performed.

When the group folder is selected, the group folder disappears in the partition of the arc character input keypad, and individual characters included in the selected group folder are arranged in each partition to display individual characters.

In addition, when the individual characters displayed on the arc character input keypad are selected, a step of inputting them into the character box is performed.

Here, the step of selecting and inputting the individual characters may include: a sliding movement selection step of sliding the thumb in contact with the screen to a position where the desired individual character appears while the group folder is selected by touching the screen with the thumb; It can be made, including; a contact separation selection input step to release the screen contact at the desired individual character position so that the selection of individual characters is made. That is, character input is performed by selecting a group folder by a touch of a screen, moving to individual characters in a group folder by sliding movement, and selecting individual characters by releasing a finger from the screen.

In addition, during the character input process, you can enter the required character or shape by performing the steps of selecting one of the special character / number transformation, Korean-English transformation, case transformation, space, and backspace placed on the vertical function selection keypad. You can.
