Abstract

The present invention relates to information input using a keyboard in an information processor such as a computer. More particularly, the present invention relates to a method of inputting a shift key, a Ctrl key, an Alt key, and the like. Since it is designed to input other keys together while pressing by hand, the input operation is inconvenient. Therefore, it is an object of the present invention to provide a method for inputting separately sequentially like a general key.

To do this, create a global variable to remember the input state of the Shift key, save it in the global variable if the Shift key is input, check the value of the global variable when the key is entered, and use the key value as it is if there is no Shift key input. If there is a key input, change the key value to the upper code code value, then initialize the global variable value to no input state and cycle to the key input standby state. Enter the code.

The messages of Ctrl and Alt can be handled in the same way, and they can be entered separately in order to perform various shortcut functions.

Therefore, in the present invention, after inputting the Shift key, Ctrl key, Alt key, etc., the user can input another key in the state of releasing the key, and thus the input operation is easy. Can be doubled.

The present invention relates to information input using a keyboard provided in an information processor such as a computer. In particular, a shortcut key input method using the Ctrl and Alt keys of a keyboard provided in an information processor such as a computer and a method of inputting a upper letter using the Shift key are provided. It is about.

There are 47 keys for character input on keyboards such as computers.

Basic characters that can be input alone without using the SHIFT key are all 47 characters, which alone is not enough for character input.

Many of these characters cannot be placed on the keyboard, because Roman characters alone have 27 lowercase letters, 27 uppercase letters, and hundreds of numbers, punctuation marks. Therefore, the letters, numbers, symbols, etc., which have a high frequency, are placed by two letters, such as basic letters and upper letters per key, and the upper letters are typed by typing the letter keys together while pressing the Shift key.

In this method, you must hold down the Shift key with one hand each time you input a frequently used upper letter, so the key operation rhythm is broken, the input time is delayed, and especially one hand can be used. The input operation is more inconvenient for the disabled.

In addition, when selecting various functions of a program by using a shortcut, it is a method of pressing other keys while pressing the control key (Ctrl) and the menu key (Alt).

In this way, the method of inputting other keys together while pressing the key must be defined as plural strokes.In general, the method of inputting one by one key sequentially is defined as a single stroke, and the Ctrl, Alt, and Shift keys are used in plural strokes. Keys are defined as new keys.

In addition, a key value generated by inputting by a separate method is defined as a basic key value, and a key value generated by inputting by a plurality of methods is defined as an extension key value.

Shift key, Ctrl key, Alt key, etc. are placed on the left and right sides of the keyboard, and two keys are provided for each type. However, the keyboard can be used only as a message of the same type without distinguishing the left and right keys. The number of messages in is small.

In general, the Ctrl and Alt keys are used as shortcuts for performing specific functions by entering them together with other keys in a plural form. In a program with many functions, the Ctrl and Alt keys are used to assign shortcut keys. The number of messages is insufficient, and the upper letter input by using the Shift key can specify only one set of characters, so it is insufficient to indicate the characters and symbols that should be used daily.

This disadvantage is because the change key must be selected from the two keys on the left and right sides according to the position of the key input together.

Despite the inconvenience of the key operation, the reason for using such a plurality of other methods is that the user needs to transmit hundreds of messages to the information processor for text input and data processing, but the number of keys provided on the keyboard is 103, which is absolutely insufficient. This is to generate more information (extension key value) other than the default key value.

The present invention facilitates key operation by allowing the key to operate in a separate way to solve the above problems, and accordingly by using the left and right side of the key to separate the message and the message that can be input from the keyboard Its purpose is to eliminate the message shortage on the keyboard, which is the default input device.

In order to achieve the above object, the present invention creates a global variable in the memory 14 to store the input state of the shift key, and when the shift key is pressed, the fact that the input is stored in the global variable, and the general key is entered, the global variable. If there is no Shift key input, the input key message is used as it is.If the Shift key is pressed, the input key message is converted to the upper code code value, and the global variable is initialized to 0 without input. Cycles through the process of waiting for a keystroke.

In this method, after the Shift key is released, the first letter immediately after the hand is released is entered as an upper letter.

Therefore, it is not necessary to press and hold the Shift key until the character key is entered when entering the upper letter.

The method of converting the key value generated by inputting the key to the code value of the upper letter assigned to each key is as follows.

In the case of Roman letters, the code value difference between the upper and lower case is constant, so the uppercase letters are the corresponding lowercase letters when 32 is added to the code values, and the lowercase letters are the uppercase codes when 32 is subtracted from the code values. Since the difference in the character code value is different, convert the code value of the character corresponding to the basic character as shown in Table 1 according to the individual character.

In Table 1 below, the basic character line indicates the character array according to the ASCII code table used as a standard, and the character string indicates the character corresponding to the key of each basic character.

For example, if the character code value is 61 (=), the code value is changed to 43 (+). If the code value is 47 (/), the code value is converted to 63 (?). Just convert it to a code value.

An alternative is to use arrays, which are created in the same order as the corresponding character lines in Table 1 and stored in memory.

To convert to a code character value, read the value into the position (address) of the character string 1 by subtracting 33 from the key value.                         

Since the first 0 address of the first letter array is arranged in order from the letter corresponding to the character code value 33, the value stored in the array of the position minus 33 from the key value becomes the code value of the character corresponding to the character.

The method of changing the code value corresponding to the key message value can be obtained by making a function and executing it in a part of processing a message generated when a key is input or other necessary place.

In addition, in order to use a set of character sets in addition to the basic uppercase letter 1 on the keyboard, as shown in Table 2, the uppercase letter 2 array is created and stored in the memory in the order corresponding to the basic character line. The character array is an example and can be defined differently by the user.

When the left shift key is input using the above-described character array, the upper letter 1 array is used. When the right shift key is input, the upper letter 2 array is referred to.

If the same method is applied to the Ctrl key and the Alt key, various shortcut functions can be executed as in the conventional method.

To cancel the new key after inputting it, reset the global variable to 0 in the part that handles the cancel key message.

In the related art, a key input generated by the keyboard 11 is classified and used in the data processing unit 13 by inputting a new key in a plurality of other methods. By using the key value, the data processing unit 13 checks the variable of the memory 14 that stores the input state of the change key immediately before, converts the default key value to upper letter, or processes the hotkey function, and then stores the change key input state. By initializing the variables (99) and circulating the way to the input standby state (1), it is characterized by being able to input all keys including the new key in a standalone manner.

Hereinafter, described in detail by the accompanying drawings as follows.

When a key is typed on the keyboard 11, a message that a key is pressed and a key value are generated and transmitted to the data processing unit 13. The data processing unit analyzes the message and the key value and stores the message and key value in the memory 14, or performs a designated shortcut function. The processing portion is displayed on the display unit 15.

The data processing unit 13 has a function of calculating a key value and the like and reading and writing data such as a key value into a memory, and the memory 14 has a function of storing data.

The present invention utilizes this function of the information processor, and as a basic operation, creates a B variable in the memory 14 to comprehensively store the input state of the three change keys, and inputs the S variable and the Ctrl key as variables to store the Shift key input state. The C variable to store the state and the A variable to store the Alt key input state are created in the memory 14, and all of them are initialized to 0, which is the non-input state.

These variables are made into global variables in the memory so that the data processing unit 13 always saves or reads the input state of the new key.

To convert the keyboard's basic letters to upper letters, create the upper letter 1 array and the upper letter 2 array in the order shown in Table 2, and save them in memory at the beginning.

In order to input the new key in a stand-alone manner in which the new key is sequentially input like the general key, the processing method when the new key is input in the part of receiving and processing the key input message of the data processing unit 13 and immediately before the new key is input The key value is divided into four cases: key input processing in the basic state without a key, key input processing with a shift key input immediately before, and key input processing with a Ctrl or Alt key input immediately before. Should be handled.

3 is a flowchart illustrating a process of inputting and processing a key, in which the input standby 1 is waiting for a key input.

First, when a new key is input, if there is a key input (2), a key input message and information of the key value are transmitted to the data processing unit 13, and the new key is checked by checking whether the key value is a new or other general key. (3) If the key value is Shift key (51), save the S variable as 11, if the B variable is 0, save it as 11, if the Ctrl key (52) save the C variable as 21, and if the B variable is 0, 21 If the A key is 53, the variable A is saved as 31. If the variable B is 0, the value is saved as 31. In this case, if the B variable that comprehensively stores the input state of the break key is larger than 1, the other B key is input immediately before, so the B variable remains unchanged. The reason for this is to know the first type of new key through the B variable when two new combinations are used. These variables store the input state of the new key.

Second, the key input value processing method in the basic state without the previous input of the change key is, if there is a key input (2), check whether the key value is a change key or other general key, and if the general key (4), the change key input state If the value of B is stored and the value is 0 (61), since there is no input of the change key immediately before, the key value is processed as it is and the input wait state (1) is entered.

Third, the key input processing method with the shift key input immediately before is, if there is a key input (2), check whether the key value is a change key or other general key, and if the general key (4), check the B variable and check the B variable. Is 11 (71), just before the Shift key is input, check the C and A variables to see if the combination with the Ctrl or Alt key is used. If it is in combination with the Shift key and other change keys, it handles the shortcut function of Shift + Shft + Key value, and if both C and A variables are 0 (72), it uses the Shift key only shortcut to check which Shift key is entered. If the left shift key (74) converts the key value to the upper letter 1 (77) character array, and the right shift key (75) converts the key value to the upper letter 2 (78) character array and then B, S, C and A variables are all used once, so initialize them to 0 (99) and enter them. The power standby state (1).

Fourth, if the Ctrl key is input immediately before the key is input, the processing method is to check if the key input (2) is a change key or other general key, and if the general key (4), check the B variable. Is 21 (81), just before the Ctrl key has been input, check the S and A variables to see if the combination of the Shift and Alt keys is used. ), It is used in combination with other keyboard shortcuts, so it handles the shortcut key function (89) of Ctrl + keyboard + key value, and if both S and A variables are 0 (82), it is the Ctrl key shortcut. If the left Ctrl key (84) processes the shortcut key function 86 of the left Ctrl key + key value, and the right Ctrl key (85) processes the shortcut key function 87 of the right Ctrl key + key value, then the used B Variable, S variable, C variable, and A variable are all initialized to 0 (99) and are in the input standby (1) state. .

Fifth, when the Alt key is input immediately before the key input, the processing method is to check whether the key input (2) is a change key or other general key, and if the general key (4), check the B variable. Is 31 (91), there is an Alt key input right before, so check the S and C variables to see if the combination of Shift and Ctrl keys is used, whichever is greater than 1 (92) If it is used in combination with other change keys, it handles the shortcut key function (98) of Alt key + new key + key value, and if both S and C variables are 0 (93), it is the Alt key alone shortcut key. After confirming, if the left Alt key (94) processes the shortcut key function 96 of the left Alt key + key value, and if the right Alt key (95) processes the shortcut key function 97 of the right Alt key + key value, it is finished. B, S, C, and A variables are all initialized to zero (99) and enter the standby (1) state.

To cancel this after entering a new key, initialize all B, S, C, and A variables to 0 in the part that handles the cancel key message.

In order to achieve the object of inputting the new key in a standalone manner as described above, variables are stored in the memory 14 to store the input state of the new key as a basic operation and initialized. First, if a new key is entered Second, if a new key is entered immediately before the second key Fifth, in the case of key input in the state of inputting the key, the method of processing kit values by dividing into the case of key input in the state of pressing the Alt key immediately before is defined as pre-key reference processing and used for pre-key reference processing. Define a key as another key.

In the above-mentioned all key reference processing, the new key can be inputted as a single key, and general keys other than the three new keys can be used as other key functions.

76, 86, 87, 89, 98, 96, and 97 of FIG. 3 illustrate various functions corresponding to shortcut keys used in combination with a new key and another key.

For example, in the case of 86 showing the shortcut keys used in combination with the left Ctrl key, set the printer using the left Ctrl key and P, search using the left Ctrl key and Q, and use the left Ctrl key and L in combination. It indicates that the shortcut function has been assigned using the combination of the left Ctrl key and other keys, such as Find again.

<Example 1>

Among the hotkey functions 96 used as a combination of the left Alt key and another key, a new document creation function is performed with the left Alt key and the N key shortcut, and a document is saved with the left Alt key and the S key shortcut. If the program is to execute the function of creating a new document and saving the document, the function is executed according to the key value in the shortcut function (96).

That is, before the key input, all of the change key variables are 0, and when the left Alt key is input 53 in the input standby state (1), a message indicating that the key is pressed and the Alt key message are received by the data processor 14, the key message is processed. After saving 31 in the B and A variables of the memory, go to the input standby (1) state. Next, when N is input (4) from the keyboard, the previous change key input state is checked through the B variable of the memory. If the B variable is 31, the Alt key is immediately input (91), so if you check whether the combination with the other key is used (93,92), the S and C variables are all 0 (93). If you use the left Alt key (94), perform new document creation function assigned to the left Alt key and N key shortcut key (96) and initialize the variables. 99) and cycles to the input standby (1) state.

<Example 2>

As an example of the shortcut key (76) that uses three key combinations such as the Shift key, the Alt key, and the letter key, the three key combinations such as the Shift key, the Alt key, and the U key are underlined characters. If the combination of the key and the D key is a program that performs functions, etc., prepare and prepare each function that performs these functions first. Before the key input, the new key variables are all 0 and in the standby mode (1), when the Shift key is input (51) on the keyboard, the key processing message 14 and the Alt key message are received. 11 is stored in the B variable and S variable of the memory at the portion, and when the Alt key is input (53) to the next step, 31 is stored in the A variable of the memory and becomes the input standby (1) state.

The B variable is 11 when the Shift key is pressed and is not changed when the Alt key is pressed. Therefore, the variable B is first stored in the B variable.

In the next step, when the D key is input (4) in the input standby (1) state, the B key is 11 (71) and the shift key is first entered. If you check the use of the combination with the other change key (73) first, since the variable A is 31, you can see that the combination of the shift key and the Alt key is used. 76) It executes the function and initializes all the variables of the return key to 0 without input (99) and cycles to the input standby (1) state.

<Example 3>

In this embodiment, a method of inputting a upper letter first converts to a upper letter by inputting a general key and then a shift key.

Referring to FIG. 2, when the general key 4 is input in the input standby 1 state, the key value is stored in the memory, and then goes to the input standby 1 state. 51) If the left and right keys are pressed, the left shift key is used (55) to convert the previous memory value into the upper letter 1 (57) array value, and if the right shift key is used (56), the previous key is entered. After converting a memory value to an upper-order two (58) array value, a rearrangement operation (59) such as moving a memory position is performed, and the state is circulated to the input standby state (1).

As described above, the present invention provides a method for inputting information using a keyboard provided in an information processor such as a computer.

Entering a letter or shortcut menu is greatly simplified by allowing all keys to be input alone using the whole-key reference processing method. It is convenient for handicapped people with disabilities. Therefore, it is possible to use left and right shift key messages separately, so that an additional 47 character set of upper characters can be additionally designated. By using the shortcut key and the message required to perform a special function can be utilized twice as conventional.

In addition, if necessary, all the basic keys such as a and h can be used as other key functions, so it is easy to expand the number of messages.
