Description

Keyboard for a one handed}

The present invention relates to a computer keyboard in which one or more keys having the same function are arranged on a single keyboard, and more specifically, the first reduced-type first keyboard part is greatly reduced in the general keyboard (106-key type) state. And a second keyboard part which is completely symmetrical in terms of the arrangement of the reduced first keyboard part and the key, and then the computer keyboard is made by combining the two keyboard parts from side to side.

The general keyboard, which has become the main character input method in computer life, can be divided into four user groups according to its behavior. In the process of using the keyboard, each user group exposes the following inconveniences and problems.

(1) For normal (right-handed) two-handed users

The keyboard commonly used in computer life is called a normal keyboard or a standard keyboard. Needless to say, the general keyboard is designed for users with both hands, and both of them are right-handed among normal users. It is made on the basis of. Although the general keyboard is made for the right-handed person whose two hands are normal, the following problems are exposed.

First, the “Back Space” key is one of the most frequently used keys in a real hitter, so the fingering should be placed in the easiest position to respond to such usage, but in general keyboards the finger is placed. It is placed two steps up from the seat (the place where eight left and right fingers are removed from the keyboard), so the fingering itself is not natural and the key is often misplaced.

Secondly, the “Korean / English Mode Conversion” key is a function key that is frequently used in actual character input. In a general keyboard, this key is placed in an ambiguous position for both thumb and other fingers. Every time we make an event, we can't decide what to do.

Third, in the numeric key separately provided on the right side of the general keyboard, 10 numbers are arranged in a four-layer structure of 3 * 4 type, and the four-layer arrangement structure is in the order of increasing numbers from the bottom up. As such, the arrangement structure in which the numbers go up from the bottom to the top is a copy of the arrangement of the numeric keys of the electronic calculator. The arrangement of numbers in the keypad of the mobile phone, which is currently used, is in descending order from top to bottom. It is reversed. If the arrangement is reversed in the number input of the two most commonly used input means, it is obvious that an association resistance occurs in the brain every time the number key is pressed.

(2) When both hands are normal and inherently left-handed

Since the general keyboard is made based on the right-handed user, when the left-handed user is typing the general keyboard, there are some inconveniences in using the user rather than the right-handed user. (11% left-handed world average)

First, since the general keyboard is created based on the right-handed user, when the left-handed user presses the numeric keys arranged on the right side of the keyboard and the accompanying operation symbols (+,-, *, /), Will not be natural. In order to improve such a problem, there is a keyboard on the market that consists of moving only the numeric keys to the left side of the keyboard, and the keyboard is left-handed only, and other function keys (for example, arrow keys) are used for the right-handed user. Since the standard is used as it is, keyboards that move only the numeric keys to the left will eventually become incomplete left-handed.

Secondly, in the general keyboard, the direction keys arranged on the right side of the keyboard are also not naturally fingered to the left handed as in the case of the numeric keys.

(3) If the hands are normal but the user mainly uses one hand due to the nature of the work

With the development of the information society, the computer life itself has been settled in a very general form, which has led to the creation of many occupations and fields that rely solely on computers to handle their work. There are many people who are engaged in such occupations or tasks, because of the nature of their work, there is no reason to take a standing position in front of a computer and handle keys with both hands, but such users have the following inconveniences.

First, users who frequently enter numbers in business (financial, accounting, storage, and formula editors) use the numeric keys provided on the right side of the keyboard almost habitually when entering numbers. In the number plate, you must move your finger up and down, so you have to play your hands up and down very distractingly. In addition, whenever a user presses a (phone) phone, which is already a universal means of number entry, and a numeric key whose sequence is reversed, it is obvious that associative resistance occurs in the brain.

Secondly, a user who works professionally with a computer often has a repetitive input. In order to improve the efficiency of the repetitive input, a combination of two or three keys executes a function in a shortcut form. However, in the general keyboard, function keys are distributed in various places, and when combining multiple keys, both hands must be used to execute a desired function. In fact, due to the nature of the task, it is hard to be able to handle multiple keys with two hands while taking a stand position in the execution of a number of repetitive shortcut keys.

(4) A user who is required to touch with only one of his right hand or left hand due to a physical disability

This group of users can use general or special keyboards according to their preferences and physical conditions.

 One of the two keyboards has the following problems.

First, when a one-handed user uses a general keyboard, the key layout of the general keyboard has a diagonal structure, which may be disadvantageous in determining the position of the key with eyes. The diagonal arrangement may have something to do with ease of fingering, but it has nothing to do with the movement of the eye. The diagonal arrangement that is commonly adopted in the key layout of general keyboards is not a problem for two-handed users who can type without looking at the keyboard, but for users who have no choice but to look at the keyboard, the position of the key is moved when moving on the keyboard. In the process of perception, disturbance of eyes occurs.

In addition, as users experience with both hands, if you execute a function by pressing a plurality of keys at the same time in the hotkey execution, such an operation is even less useful for a one-handed user.

Next, if a one-handed user uses a keyboard that has a special arrangement of keys (for exclusive use), the difference between the special keyboard and the normal keyboard will be different from the general format of the general keyboard. There will be many, and that will create many troublesome problems. In addition, the special keyboard can only be used by one-handed users, and it will be inevitable for the keyboard producers to produce a small amount, and the price of the keyboard becomes quite expensive.

The present invention solves the exposed part of the general key layout, which has been raised above, and then the left-handed person who has inherently disadvantageous conditions in terms of keyboard use compared to the right-handed person, and the physical reason or job. It is to provide a keyboard that can increase the input convenience for the one-handed users who are forced to handle the keyboard with only one hand in nature.

More specifically, the first object of the present invention is to provide a keyboard with an oblique array structure exposed as a problem in a key layout of a general keyboard and an arrangement of keys so that function keys having a high frequency of use are adapted to the frequency of use. There is.

The second object of the present invention is to provide a keyboard with high input convenience by optimizing a key arrangement structure for a left-handed user who has a relatively unfavorable typing condition compared to a right-handed user.

And the third purpose of the present invention, the user who is forced to touch with only one hand due to physical disabilities, and the one-handed user who uses only one hand due to the nature of the task in charge, The key is to provide a keyboard with a significant improvement in typing conditions so that the position of the key to be pressed is the shortest distance, so that all types of keys can be made within the range of the fingers of the keys arranged with the characters and the keys arranged with the functions. .

In order to solve the above technical problem, the one-handed user keyboard according to the present invention proposes the following solution in its configuration.

First, in the keyboard according to the present invention, the keys are arranged in perfect symmetry on the left and right sides of the keyboard.

Since the general keyboard is made for a user with both hands, the typing condition is very poor for a one-handed user, and the general keyboard is made for a right-handed user. It is. In order to improve the typing conditions that are disadvantageous for left-handed users and single-handed users, the keyboard according to the present invention arranges letter keys and function keys on one keyboard on the left and right sides of the keyboard, resulting in two keyboards on one keyboard. The keyboard was configured to be executed independently. By doing so, the right-hand side of the keyboard can be used by the right-handed user and the left-hand side of the keyboard by the left-handed user, so that there is no distinction between left-handed and right-handed. Thus, two groups of users who are heterogeneous in terms of other behaviours can share a keyboard.

Secondly, in the keyboard according to the present invention, the arrangement of the keys consists of a matrix structure.

If you use both hands on the keyboard, you will be able to hit the keyboard without looking at the keyboard because the key will match the ratio of three keys to one finger. Even if you're mastered, it's never easy to do it without seeing the keyboard. Therefore, the one-handed user has no choice but to determine the position of the key by shifting the line of sight. At this time, if the arrangement of the keys has a diagonal structure like a general keyboard, it is obvious that the line of sight is disturbed and the input efficiency is reduced. In order to solve such a problem, in the present invention, the diagonal key arrangement structure of the general keyboard is composed of a matrix.

Third, in the keyboard according to the present invention, a key assigned to a character and a key assigned to a function are arranged on both sides of the keyboard by at least one or more sets.

Since the general keyboard was created based on the right-handed user among the users with normal two-handed hands, it is possible to use only one-handed (naturally born) users, physically impaired, or inevitably with one hand. The one-handed users who work frequently are relatively disadvantageous to the right-handed people in terms of typing conditions. In order to improve such a problem, the keyboard according to the present invention is configured such that at least one or more keys (characters, Korean, English, numbers, symbols) or functions assigned to one keyboard are arranged. That way, regardless of where the left-handed or one-handed user's hand is placed on the keyboard, the position of the current typing finger and the next key you want to press is the shortest possible distance. It is possible to make a deal.

Fourth, in the keyboard according to the present invention, the function keys included in the left portion of the keyboard and the postal portion of the keyboard are configured to share both keyboard portions.

In the keyboard according to the present invention, the left and right keyboard parts are completely symmetrical, and the left and right keyboard parts constitute one independent keyboard, and the function keys shared by the two keyboards are arranged in the center portion where the two keyboard parts are combined, so that both keyboards are used with one hand only. Conditions that can be reached will be established. As a result, the keyboard according to the present invention is to make a key for both sides to share the function keys arranged at the center of the two keyboard parts in a state where there is no distinction between the right-handed user and the left-handed user (the two are integrated into one). . If you do so, you will be able to hit the other side with only one hand, and eventually the left-handed and one-handed keyboards will be integrated into one keyboard.

According to the one-handed user keyboard according to the present invention, in the state where the left side and the post of the keyboard have a symmetrical structure, two sets of common letter keys are arranged in the left and right sides, so that a left-handed user and a right-handed user can share a single keyboard. Since the arrangement of keys arranged with general characters has a matrix structure, the one-handed user moves the eyes and does not disturb the eyes when judging the position of the keys. The function keys are configured in a form shared by the left and right sides, so that users who are in any other typing condition can be used regardless of whether they are left- or right-handed user groups. At least one character key (Korean, English, numbers, symbols) and function keys on a keyboard Arranged so that the fingering distance from the location of the user's finger to the next key is the shortest distance, so that any type of keystroke within the range of the finger's range of all character and function keys, even for single handed users It becomes possible.

In this case, the left-handed user and the right-handed user can use a single keyboard according to the present invention, so that the distinction between the left-handed keyboard and the right-handed keyboard is eliminated. Since any type of gun can be made to the location, the result is that the keyboards of left-handed, right-handed, and one-handed users are integrated into a single model.

In the following paper, we will describe one-handed users who are relatively inferior to left-handed users in terms of typing conditions. The reason for describing one-handed users as a priority is that left-handed keyboards (two-handed) are better in terms of typing than one-handed ones, and they are based on one-handed users with less typing. This is because other user groups having better circumstances can be considered to be included in the typing condition of the one-handed user group.

Hereinafter, with reference to the accompanying drawings will be described in more detail the structure and the embodiment of the keyboard according to the present invention. In describing the embodiments, in view of the fact that the field of the computer keyboard to which the present invention belongs is very generalized, the descriptions of the known technologies will be omitted. This is to more clearly convey the gist of the present invention by omitting unnecessary description of the technical contents.

1. Miniature Keyboard  Configuration

1 is a view for explaining the membership of the reduced keyboard in the keyboard according to the present invention, the key and the total number of keys and the arrangement of keys in the keyboard according to the present invention is shown in contrast with the key It can be seen that both differ in terms of how to arrange the keys on the keyboard and the total number of keys.

Since the general keyboard was originally made based on the right-handed user among the users with both hands, the disadvantage of the typing condition for the left-handed or one-handed user is inevitable. In order to solve such an original problem, the number of keys should be optimized for left-handed and one-handed users, and function keys (such as Scroll Lock and Pause Break), which are not used in general keyboards (106-key type), are assigned to other function keys. It is possible to construct a reduced size keyboard unit which reduces the number of keys by merging or integrating overlapping symbol keys (operation symbols of the right numeric key unit) into one.

As shown in FIG. 1, in the general keyboard and the reduced type keyboard, the correspondence relation between the keys is 26 letters, 10 upper number keys, and 12 Fn (n = 1 ~ 12) keys. It is accommodated almost in its original shape, and the numeric keys arranged at the bottom right of the general keyboard and the accompanying operation symbols (+,-, *, /) are accommodated at the bottom of the reduced keyboard part, but the general character keys are not out of the horizontal width arranged. Are arranged without. In this way, the width was reduced from 10 keys to 22 keys in the general keyboard and became 12 keys, and the vertical width increased from 2 keys to 6 keys in the general keyboard to 8 keys. Therefore, the reduced size of the keyboard portion as a whole, the vertical width is increased by 2 keys as the width is reduced by 10 keys, the number of keys reduced by the type of keys is shown in [Table 1].

[Table 1] shows how the number of keys is reduced by type of keys. In the 106 key type of the general keyboard, all 24 keys are reduced, and a reduced size keyboard part composed of 82 keys is formed. The form is a way to make up for the left-handed and one-handed users to make up for the disadvantages in terms of typing.

2. Symmetrical array structure

2 is a view showing the symmetrical structure of the left and right keyboard portion in the keyboard according to the present invention, the first reduced type keyboard portion (hereinafter referred to as the first keyboard portion), and the first keyboard portion and the key keyboard and the arrangement of the key completely The second reduced type keyboard part (hereinafter referred to as the second keyboard part), which is symmetrical, is further configured, and then the two keyboard parts are combined to the left and right to form a completed keyboard.

As shown in FIG. 2, in the basic concept of the configuration of the keyboard according to the present invention, 26 general letter (Korean and English) keys normally provided on the general keyboard are divided into a pair of first and second keyboard portions, respectively. Numeric keys arranged on top of the general keyboard and numeric keys separately provided on the right side of the keyboard are divided into one by one, respectively, and a plurality of special character keys are arranged on the first and second keyboard portions. Each of them is arranged in pairs, and twelve Fn (n = 1 ~ 12) keys are arranged in a pair of first and second keyboard portions, respectively. Here, the letters or function keys arranged in a pair of first and second keyboard portions are arranged so as to be symmetrical in terms of their arrangement.

Since 12 Fn (n = 1 ~ 12) keys are less frequently used than other function keys, it is not necessary to arrange two sets on one keyboard to achieve symmetrical structure. It is more useful to arrange at the center of. In addition, if you arrange a set of 12 Fn keys into the center of the keyboard, a space will appear on the left and right sides of the Fn key, and the shortcut keys (save, copy, paste, cut, print, and close the window) will be assigned to the first and second keyboards. It is possible to arrange one piece for each division.

On the other hand, in the keyboard according to the present invention can put the second array type in the general character key arrangement portion to be executed in the selective mode. As shown in FIG. 8, in the Korean second arrangement type, a general character is placed on a general character key, and in the first line, (M / ㅈ)-(L / c)-(D / ㅅ)-(Z / ㅂ) -(Q / q)-(J / v, v)-(B / v, v)-(P / v, v)-(G / v, v)-(K / v)} The second line contains {(N / ㄱ)-(R / b)-(T / ㅇ)-(S / ㄹ)-(H / ㅁ)-(U / TT, ㅠ)-(A / ㅓ, ㅕ)- (E / ㅣ)-(O / ㅏ, ㅑ)-(I / ㅡ)} and the third line contains {(F / ㅊ)-(V / ㅌ)-(X / ㅋ)-(C / ㅎ)-(space)-(Y / ㅚ, ㅟ)-(W / ㅘ, ㅙ)}

As another example, as shown in FIG. 9, in the English second array type, the general characters are arranged in the general character key, the first line is arranged in the order of {MLDZQJBPGK}, and the second line is arranged in the order of {NRTSHUAEOI}. , On the third line, {FVXC- (space) -YW}.

The general character array format adopted by the general keyboard and the optional array format shown above are written together on the keyboard as a relationship between the basic type and the user selection type, and when one of the two array types becomes the basic type, the other type is configured to be the user selection type. .

3. Matrix Structure of Plain Character Keys

3 is a view for explaining that the general character key is a matrix (checkerboard) arrangement structure in the keyboard according to the present invention, unlike the general keyboard has a diagonal (upper left line) arrangement structure, In the keyboard, you can see that the vertical and horizontal lines are made like a checkerboard.

The letters (Hangul, English, numbers, symbols) of the common keyboard are arranged with the upper and lower lines arranged opposite to each other, whereas the keyboard according to the present invention has a matrix structure. When the arrangement of the keys forms a straight line up, down, left, and right like the keyboard according to the present invention, the one-handed users who need to check the position of the keys with their eyes, the phenomenon that their eyes are momentarily disturbed when the eyes are moved on the keyboard Not only disappear, but also has the effect of shortening the distance to move one eye.

4. Left and right Keyboard  Shared key area

4 is a view for explaining that the central portion of the keyboard in the keyboard according to the present invention is a shared key area, the keys belonging to the portion of the left and right keyboards combined in the state that the left and right keyboards are completely symmetrical in the arrangement of the keys, the left and right keyboards It shows a wealth sharing area.

As shown in FIG. 4, in the shared key area, a character mode (eg, Korean / English) conversion key, CapsLock key, Tap key, BackSpace key, Enter key, Shift key, PageUp / Down key, Home / End key, and direction key Is placed. In this case, virtually all of the key function keys are placed in the shared area in the center of the keyboard. Thus, since there is an area shared by the left and right keyboard parts on one keyboard, the right-handed and left-handed one-handed users You will have the conditions to share the keyboard.

Meanwhile, in the keyboard according to the present invention, special characters are arranged in two forms, one of which is a type in which only special characters are arranged alone, and the other is in a format in which common characters are written together in a key. If special characters are combined with regular characters, they are arranged one by one key. If only special characters are arranged, two by one key. When only special characters are arranged, the operation symbols (+,-, *, /, =) related to the numeric input should be arranged in the format immediately adjacent to the numeric keys, so that the general character keys and the numeric keys will be shared.

5. One-handed  Of your Fingering

5 is a view for explaining the ease of fingering of a one-handed user in the keyboard according to the present invention, it is shown that the key keys can be easily keyed by using the left and right thumb.

As shown in FIG. 5, in the keyboard according to the present invention, not only the shared key area of the central part of the keyboard, but also other function keys are disposed within a range in which a thumb can be easily pressed. Therefore, no matter which position the one-handed user's hand is in, the position of the current key and the next key are the shortest distances. Form keystroke is possible.

Furthermore, as shown in [Table 2], the keyboard according to the present invention has many keys having the same function than the general keyboard, so that the structure best suits the one-handed user's keystroke behavior.

In the keyboard according to the present invention, not only the number of keys is increased, but also the input efficiency is increased by shortening the distance from the current finger position to the next function key. For example, when using only one hand in one of the keyboards on the left and right sides, the space key, the back space key, the shift key, and the enter key, which are most used in the actual batter, are arranged at least two or more fingers at the current position. Even if you move a little, up, down, left, or right, you can enjoy the desired key.

What's more, when two or more function keys are combined using only one hand to perform a shortcut function, you can naturally press two different keys together. For example, if you need to press two different function keys at the same time, such as Ctrl-Alt, Ctrl-Shift, Ctrl-Enter, Shift-Enter, Ctrl-direction keys, etc. The distance between the function keys is so short that you can easily execute the shortcut function with just one hand.

On the other hand, if you look at the arrangement of the numeric keys, the numeric keys are arranged in two places. One is arranged in direct connection on the normal character key. (+,-, *, /) Are arranged in immediate neighboring form.

On the other hand, in the arrangement of the numeric keys according to the present invention, two types of arrangement methods are taken as in the general keyboard, and the numeric keys arranged at the bottom right of the keyboard are composed of two rows and five columns. The arithmetic symbols (+,-, *, /) and the minor symbols (dots, commas) directly related to the numeric input are arranged to be directly connected to the numeric keys, and the numbers and the mathematical symbols are placed within the left and right width ranges where the character keys are arranged.

6. In case of array of normal characters Example

FIG. 6 is a view showing an arrangement area of general characters in a keyboard according to the present invention, in which general characters are arranged in a basic array unit, an expansion array unit, and a variable array unit according to the number of general character keys typically provided in a corresponding language. It can be shown.

Computer keyboards were originally designed in the United States, which means that 26 letters of the alphabet are primarily arranged in the basic type in any type of character in the world, and the letters are somehow stitched and aligned to the English basic type. However, if the local keyboard fails to assign all 26 keys with alphabetical letters arranged in the English alphabet, it expands to the upper numeric key area or expands to the variable array part and allocates the remaining general letters anyway.

As shown in [Table 3], in the keyboard according to the present invention, in the language in which the national characters can be assigned to 26 keys in which the English alphabet is arranged, the general characters are assigned to only one basic arrangement unit (FIG. 7A), and up to 40 basic characters are used. Allocating to the array portion and the expansion array portion (Fig. 7b), if there are more than 40, the general character is allocated to all three places, the basic array portion, the expansion array portion and the variable array portion (Fig. 7c).

As shown in [Table 3] above, there are English, Korean, Chinese (Roman food), and Japanese (Roman input method) as well as English. French, Arabic, Russian, Chinese (Taiwan major sign), etc. are used as the allocation area up to the array part, and Japanese (Hiragana) is used for the language used as the allocation area up to the basic array part, the extended array part, and the variable array part. Way), Thai, and Hindi.

In the keyboard according to the present invention, the expansion arrangement is provided in the upper numeric key region will be described with reference to FIG. 7B. As shown in FIG. 7B, the keyboard according to the present invention shows that characters over the basic 26 keys may be arranged in the upper numeric key arrangement portion, wherein the characters extended to the upper numeric key arrangement area in the keyboard according to the present invention. First of all, I'll explain the difference between arranging the characters and arranging extended characters in the upper numeric key area.

In general keyboards, the extended characters are arranged together with numbers (array), but in the keyboard according to the present invention, the extended characters are arranged purely without placing numbers in the upper numeric key area. Then, not only is the arrangement itself felt concise, but the input efficiency is much higher. The reason for the higher input efficiency is that, in the case of numbers and extended characters, as in the general keyboard, when you enter a character placed in the extended area, you must hold down the Shift key and press the key where the character is placed. However, in the keyboard according to the present invention, since the numbers are not arranged in the numeric key area, the characters arranged on the corresponding keys are input at one stroke. That is, in the general keyboard, the characters arranged in the extended area are inputted only when two keys are pressed together. However, in the keyboard according to the present invention, the numbers are not arranged in the upper numeric key area. Will be.

In the keyboard according to the present invention, since the general characters are arranged only up to the extended array portion, the variable array portion becomes blank. Shortcut function keys such as Save, Copy, Paste, Cut, Cut, and Close may be variably arranged in a blank key.

The general characters are arranged in the variable array units provided on the left and right sides of the keyboard with reference to FIG. 7C. The variable array part is where Fn (n = 1 ~ 12) keys are arranged in the reduced keyboard part, and the Fn (n = 1 ~ 12) keys, which are less frequently used compared to other keys, need to be placed on one keyboard. As a result of gathering and arranging 12 Fn (n = 1 ~ 12) keys into the center of the keyboard, there is no reason for the punishment, and there is a space on the left and right sides of the keyboard. Will be.

Since Fn (n = 1 ~ 12) is less frequently used than other keys, it is not necessary to have two sets and arrange them on the left and right plates, so two sets of Fn (n = 1 ~ 12) keys It is integrated into one and moved to the center of the keyboard to secure space on the left and right sides of the keyboard, and to use the space as a variable array.

Languages that require regular characters to be assigned to the variable array include Japanese (Hiragana), Thai, Hindi, and Bengali. These languages have too many alphabets to input, so when you arrange common characters on the keyboard, At least 40 keys are required.
