Description

Key Arrangement For A Keyboard}, which is displayed in the order of the QWERTY keyboard layout,

More particularly, the present invention relates to an input device for an English input device, which is arranged in a matrix of a specific size so as to form a keyboard having a size enough to be easily touched or pressed by a user in a mobile phone or a smartphone, To an alphabetical alphabetical letter display board in which two alphabets are displayed and at least one alphabetic character plate is displayed in the order of the alphabetic alphabetic character arrangement in order to improve the typing speed and reduce the number of typing characters.

The English version of the English alphabet, which has 26 alphanumeric characters, has been developed from English typewriter to computer keyboard, mobile phone keyboard, and smartphone screen. Among these keyboard layouts, QWERTY keyboard is the most widely used keyboard layout among English keyboard layouts. FIG. 1 is a schematic diagram showing a QWERTY English input keyboard. This QWERTY keyboard was invented and patented by Christopher Scholl in the United States in 1868, and in 1873 he sold a patent on QWERTY keyboard to Remington. Remington then applied the QWERTY keyboard for the production of English typewriters and was judged to be inferior to the Dvorak keyboard that was adopted as a standard keyboard by the American National Standards Institute (ANSI) at the time. However, I got to prefer the keyboard.

The QWERTY keyboard is an arrangement of keyboards arranged so that the most frequently used alphabets are located farthest from each other. At that time, when English typewriters hit the adjacent keyboards successively, the problem of tangling the keyboard frequently occurred, and the keyboard layout to solve this was the QWERTY keyboard. Based on this, QWERTZ keyboard in Germany and AZERTY keyboard in France were produced.

However, when the QWERTY keyboard is implemented in a smartphone or a mobile phone, the size of the keyboard becomes too small. For a smartphone with a 5.5 inch screen, the width of the QWERTY keyboard is 0.6 cm, the length is 0.74 cm, the horizontal separation distance between the keyboards is 0.1 cm, and the vertical separation distance is 0.25 cm. Assuming that each keyboard shares the spacing between the keyboards as a touchable space, the touchable space for each keyboard is 0.8 cm in width and 1.24 cm in height, and the touchable space per keyboard of the QWERTY keyboard is 0.992 cm ² . It can be seen that the keyboard is implemented on the touch screen of the smartphone quite small compared to the keyboard size of the computer keyboard having the size of 1.5 cm x 1.5 cm and the width of 2.25 cm ² .

In the case where a keyboard is actually implemented such that it can be felt by a finger like a feature phone rather than being implemented on a touch screen, a lot of typos are not generated even if the size of the keyboard is small. In particular, In the case of a phone, since the bending of the keyboard can not be sensed with a finger, the user often touches the unintended keyboard, thereby increasing the occurrence of typos.

In order to overcome the small size of the keyboard in the smartphone, there has been an attempt to enlarge the screen width of the smartphone. However, when the screen of the smartphone, that is, the size of the liquid crystal, is large, it is inconvenient for the user to grasp with one hand, inconvenient to put in a pocket, and too heavy, which is disadvantageous for use by women or minors. As a result, attempts to widen the screen width of the smartphone have been discontinued, and the screen width of the smartphone has converged to 4.5 to 6 inches.

There has been an attempt to display a plurality of characters on a keyboard in order to increase the size of the keyboard in the existing smartphone screen. That is, in order to maximize the size of the keyboard in a smartphone or a mobile phone, a half-QWERTY keyboard that displays 2 to 4 alphabets on a keyboard has been developed, so that the first alphabet can be input by pressing the keyboard only once And the second keyboard is configured to input the keyboard by pressing the keyboard twice. 2 is a schematic diagram showing a half-QTY English input keyboard.

However, the following problems occurred in the half-QTY English input keyboard. First, if the alphabet with a high frequency of use is displayed on the second keyboard, you have to press the keyboard more than once when entering it. Second, if you want to input the first alphabet in two consecutive times, A problem of having to set a time interval, and thirdly, when the user desires to input a second alphabet, a problem that two first alphabets are input may occur when he / she is pressed slowly (consonant concatenation phenomenon). Due to these problems, the frequency of use of the alphabet which can be occupied by one touch (hereinafter referred to as the occupancy rate) is only 59.0353% based on the frequency of use of the English alphabet (Concise Oxford Dictionary, 11th edition revised, 2004).

Such a problem causes a problem in that the typing speed is decreased due to an increase in the number of users in a smart phone or a mobile phone, which can cut off communication on a social network and cause a frustration to the user. On the network, users are becoming increasingly impromptu thinking, wanting to respond more and more quickly, getting accustomed to the ongoing delivery and acceptance of information, and not expecting the virtue of patience for users. Therefore, a more efficient English input board is needed in smartphones and mobile phones.

As shown in Tables 1 and 2, the frequency of use of each alphabet may vary depending on the irradiation range. In one embodiment of the present invention, based on Oxford dictionary data, calculation of occupancy rate is also calculated based on Oxford dictionary data.

Because smart phones have limited space, key size and space allocation are very important. Hereinafter, the alphabet display order, the matrix size, the number of alphabets, the method of selecting the first alphabet and the second alphabet, the function keys, and the like will be described in accordance with an embodiment of the present invention.

Alphabetical display order of English alphabet

According to an embodiment of the present invention, at least one alphabetic character plate may be provided, and such character plate is defined as a single character plate. The first alphabet may be displayed on such a single keyboard. A keyboard that is not a single keyboard may be displayed with a first alphabet and a second alphabet. The alphabetical letter input panel according to an embodiment of the present invention can display the first alphabet in the order of the QWERTY English alphabet. According to this, there is an effect that the readability of the user is improved, and accordingly, the user's adaptation time of the keyboard is shortened.

Matrix Size of English Input Keyboard

The matrix size of the English input device according to an embodiment of the present invention may be arranged in a 3x7 array. Compared to the existing half-QWERTY keyboard with 3x5 array, the keyboard size is smaller than the QWERTY keyboard, although the size of the keyboard is smaller than the half-QHTY. According to the embodiment of the present invention, when the English input device is composed of 3 × 7, it can be confirmed that the width of the keyboard of the QWERTY keyboard is twice as large as that of the keyboard. This is close to the width of the keyboard of the computer keyboard, which is not inconvenient for the user to touch.

When the alphabetical input keypad is composed of 3 × 8, the width of the keyboard is less than twice the keyboard width of the QWERTY keyboard, thereby causing a problem that the existing QWERTY keyboard has a problem.

When the alphabetical letter input panel is composed of 3 × 6, the width of the keyboard is sufficient, but the occupancy rate occupied by the first alphabet is lowered to 90% or less. Also, when the alphabet input board is composed of 3 x 6, it is very difficult to configure it as an array of QWERTY keyboards.

When the English alphabetical keypad is composed of two lines, the width of each keypad is shortened, making it difficult to touch or press the keyboard. This is because fingers are longer than horizontal and vertical.

When the English alphabetical keypad is composed of four lines, the length of the entire keyboard layout becomes long, and the fingering distance of the user becomes long. This is because the user prefers to move only the finger while the hand is fixed when touching or pressing the keyboard.

Number of keyboards

With respect to the number of keyboards in the English input device, the English input device according to an exemplary embodiment of the present invention sticks to a 3 x 7 array, and in order to prevent user mislabeling, The number may be 17 to 21, preferably 19 to 20. At this time, since the number of alphabets used in the English alphabets is limited to a total of 26, one or two alphabets can be displayed on at least one alphabetic keyboard of the alphabetic alphabetic character plate. The number of keyboards means the number of English keyboards, and various function keys can be additionally provided in English keyboards.

Method for selecting first alphabet and second alphabet through use frequency

Regarding the alphabet displayed on each keyboard, when two alphabets are displayed on one keyboard, one can be displayed as the first alphabet and the other as the second alphabet. Only the first alphabet is displayed on the single keyboard. In case of the first alphabet, the corresponding keyboard is pressed once (one touch). In the case of the second alphabet, the corresponding keyboard is pressed twice (double-touch) or input using the second key, which is a function key described below. With respect to which alphabet of each alphabet is the first alphabet or the second alphabet, the frequency of use of each alphabet is determined.

According to an embodiment of the present invention, the upper frequency of use frequency can be represented by the first alphabet. In this case, you can change the frequency of use, h, and frequency of use in Wikipedia letter data to reflect both Oxford dictionary data and Wikipedia letter data. That is, one embodiment of the present invention is an ideal alphabet input board constituted by considering Oxford dictionary data as a basic arrangement and supplementing the Wikipedia letter data. In Wikipedia letter data, the h alphabetic rate is significantly higher than the Oxford dictionary data, so if the first letter h is excluded, it leads to a low share according to the Wikipedia letter data. Therefore, in order to prevent loss due to h, which is generated based on Oxford dictionary data, it is possible to change d to the first alphabet by changing the order of h and frequency of use.

According to an embodiment of the present invention, the frequency of use frequency can be represented by the second alphabet. For example, at least one of the alphabets with a frequency of use of 2% or less can be selected and displayed in the second alphabet. Based on the Oxford dictionary data, alphabets with a frequency of use of 2% or less are f, y, w, k, v , x, z, j, q, and based on the Wikipedia letter data, the alphabet of less than 2% of usage frequency will be y, p, b, v, k, j, x, q, z. The common alphabets are y, k, v, x, z, j, q. An alphabet of less than 2% of the frequency of use referred to in one embodiment of the present invention may be selected on the basis of Oxford dictionary data, may be selected based on Wikipedia letter data, and may be less than 2% Usage frequency in alphabet and Wikipedia letter data may be selected by intersection or union of alphabet less than 2%.

The second alphabet may be displayed in a smaller size than the first alphabet, may be displayed in superscript or subscript, and may be displayed so as to highlight differences in sensation, such as different colors, even if they are displayed in the same size.

Function key

A function key according to an embodiment of the present invention may include a second key, a shift key, and an Alt key.

Regarding the second key, the second key is a function key for inputting the second alphabet. FIG. 9 illustrates an English input device according to a fourth embodiment of the present invention. The second key according to an embodiment of the present invention may be disposed on one side of the English keyboard as shown in FIG. When a key board on which the second alphabet is displayed together with the second key is pressed, the second alphabet is input. Also, when the second key is pressed, the second alphabet is inputted even when the key plates sequentially displayed with the second alphabet are pressed. If the second key is pressed for this purpose, the second mode may be configured to enter the second mode in which the second alphabet is input for only one key. After entering the second mode and inputting the second alphabet, the user may enter the basic mode again to input the first alphabet. At this time, when the key board having only one alphabet is pressed with the second key, the displayed alphabet may be inputted. Further, when a symbol or a numeral is displayed on a keypad on which the second alphabet is not displayed, it is also possible to input a symbol or a numeral by the second key.

The second alphabet may be input when the second alphabet is displayed twice, or two first alphabets displayed may be inputted. However, the English alphabet input board according to an embodiment of the present invention is configured to input the second alphabet only when the second key is used, and when the second alphabet is displayed twice, the first alphabet displayed is input So that the user can input the English alphabet as quickly as possible. Thus, it is possible to eliminate the consonance phenomenon of consonants, which is a problem in the conventional Half-Qwerty.

The English input device according to an embodiment of the present invention overcomes the existing half-QTY alphabetic keypad in the occupancy rate occupied by the first alphabetic character, and shows efficiency not to be compared by the second key.

With respect to the shift key, the shift key is a function key for entering an uppercase alphabet. The shift key according to an embodiment of the present invention may be disposed on one side of the English keyboard. If you press a keyboard with a shift key and a specific alphabet, the uppercase alphabet is entered. Also, if you press the shift key and then sequentially press a key that has a specific alphabet, the upper case alphabet of the alphabet is also entered. If the shift key is pressed for this purpose, it can be configured to enter an upper-case letter mode in which an upper-case alphabet is input for only one letter. After entering an upper case letter mode and inputting an upper case letter alphabet, the user may enter the basic mode again to input a lower case letter. Also, for convenience of the user, if the shift key is pressed twice, the uppercase letter mode can be maintained. If the shift key is pressed three times, the held uppercase letter mode can be released.

In relation to the Alt key, the Alt key is a function key for entering a symbol or number. According to an embodiment of the present invention, each keypad may be displayed with a different symbol or number, and the Alt key according to an embodiment of the present invention may be disposed at one side of the English keyboard. If you press a keyboard with a specific symbol or number with the Alt key, the corresponding symbol or number is entered. Also, if you press the Alt key and then sequentially press the keyboard with a specific symbol or number, the corresponding symbol or number will be entered. If the Alt key is pressed for this purpose, it can be configured to enter the symbol number mode in which only one digit is inputted. After entering the symbol number mode and inputting one symbol or number, it is possible to enter the basic mode again and input a lower case alphabet. Also, for convenience of the user, if the Alt key is pressed twice, the symbol number mode can be configured to be maintained, and if the Alt key is pressed three times, the symbol number mode that has been held can be released.

Example

FIG. 3 is a schematic diagram of an alphabetical input board in which the number of alphabetical letters of the alphabetical alphabetical alphabetical board is 19, excluding the function keys, according to the first embodiment of the alphabetical alphabetical arrangement according to the first embodiment of the present invention. In the case of the smartphone of the 5.5-inch screen, as shown in the figure, it may be constituted by 3 rows and 7 columns of keyboards, each of the keyboards may have a width of 0.73 cm and a length of 1.00 cm. 0.3 cm, and the vertical separation distance may be 0.3 cm. Assuming that each keyboard shares the separation distance between the keyboards as a touchable space, the touchable space per keyboard is 1.33 cm in width and 1.60 cm in height, and the touchable space per keyboard of the QWERTY keyboard is 2.128 cm ² . According to the first embodiment of the present invention, the touchable space per keyboard is 2.128 cm ² , which is close to the keyboard width of the keyboard, so that it can be seen that it is configured to sufficiently cover the width of the finger end.

Regarding the occupancy rate of the English input device board according to the first embodiment of the present invention, the occupancy rate is calculated on the basis of that shown in FIG. 3 as follows. In the Oxford dictionary data, w (1.2899%), e (11.1607%), r (7.5809%), t (6.9509%), u (3.6308% (5.7351%), d (3.3844%), f (1.8121%), g (2.4705%), h (3.0034% , the use frequency of b (2.0720%), n (6.6544%) and m (3.0129%) together shows the occupancy rate of 92.2632%. It can be seen that the English input device according to the first embodiment of the present invention is significantly improved as compared with the half Qwerty (59.0353%). The calculation of the occupancy rate may be derived by increasing or decreasing the frequency of use of the second alphabet at 100%.

In the English input device according to the first embodiment of the present invention, q, y, j, k, x, and v selected by the second alphabet are alphabets with a frequency of use of 2% or less. However, in relation to p selected by the second alphabet, the frequency of use of p is 3.1671%, which is the alphabet whose frequency of use exceeds 2%. In order to implement the QWERTY keyboard layout according to an embodiment of the present invention, p (3.1671%) which is less frequently used than the adjacent o (7.1635%) is represented by the second alphabet. A second key 10, an Alt key, a shift key, a backspace bar, a space bar, a HanYoung key, a symbol key, an enter key, and the like may be formed outside the English input device according to the first embodiment of the present invention.

With respect to the second, third, and fourth embodiments of the keyboard layout, the order of the first alphabet may be selected to match the order of the QWERTY keyboard, and the order of the second alphabet may be arranged in a more efficient order.

FIG. 4 is a schematic diagram of an alphabetical input board in which the number of alphabetical letters of the alphabetical alphabetical alphabetical board, excluding the function keys, is 19 according to the second embodiment of the alphabetic alphabetical arrangement according to the second embodiment of the present invention. It may be composed of the same number of keyboards and keyboard layout as the English input keyboard according to the first embodiment of the present invention. However, the order of the first alphabet w and the second alphabet q and the order of the first alphabet l and the second alphabet k may be reversed. That is, the second embodiment of the keyboard layout is one embodiment in which the first alphabet is always arranged to precede the second alphabet.

FIG. 5 is a schematic diagram of an English input keypad in which the number of alphabetical letters of the alphabetical alphabetical letterboard is 19, excluding the function keys, according to the third embodiment of the keyboard layout. It may be composed of the same number of keyboards and keyboard layout as the English input keyboard according to the first embodiment of the present invention. However, the second alphabet, x and v, may consist of the second alphabet of c, the second alphabet of b, and may be configured to precede each first alphabet.

It may be composed of the same number of keyboards and keyboard layout as the English input keyboard according to the first embodiment of the present invention. However, notwithstanding the principle of the present invention for arranging in the order of the QWERTY alphabetical letters, p can be expressed in the first letter in the third row and the first column. As the frequency of use of p is 3.1671%, it can be confirmed that the occupancy rate is improved to 95.4303%.

The second key, the shift key, and the alt key described above are simply terms for expressing their roles, and they can be represented by symbols such as arrows and can be defined by other terms. Although the present invention has been described above with reference to a smart phone, the present invention is not limited to a smart phone, and may be applied to a general mobile phone having a keypad. The English input device according to an embodiment of the present invention may include an array of mutually varying arrays of the arrays described above.

Also, if the alphabets are randomly displayed, it is difficult for the user to provide high readability. Therefore, according to an embodiment of the present invention, at least some of the keyboards may be configured in the order of the QWERTY keyboard. That is, each of the keyboards can be configured in the order of the QWERTY keyboards as long as the principle of displaying the first alphabet and the second alphabet is not affected. That is, the positions of the first alphabet and the second alphabet may be varied.

Alternatively, the vowel constituted by a, e, i, o, and u may be arranged in a row in the central row or central column of the keyboard, or may be constructed by driving the vowel on one side of the keyboard. In this case, the vowel may be composed of the first alphabet regardless of the frequency of use. When the vowels are constituted by the first alphabet and are arranged at one side of the keyboard, readability is improved.

As described above, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention.
