DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input / output device, and more particularly to a data input / output device for displaying a character corresponding to a key code input from a keyboard on an output device.

[0002]

2. Description of the Related Art Conventionally, when inputting data in a data input / output device of this kind, an operator accustomed to keyboard operation usually places each finger on a predetermined key which is a home position of the keyboard, and directly presses the key. Key input at high speed without looking. A so-called key input by blind touch is performed.

However, in such a high-speed input by blind touch, if the position of the operator's finger is shifted from the home position, characters different from intended characters may be continuously input. In correcting such erroneously input characters to correct characters, in the conventional data input / output device, the user must notice the erroneous input and then move the cursor to the start position of the erroneously input character to re-input the correct character. Therefore, there is a problem that operability is poor and character input cannot be performed efficiently.

[0004] An example of a data input / output device for converting and displaying characters with correct character keys by simple operation without re-inputting erroneously input characters as described above is disclosed in Japanese Patent Publication No. Sho 61-1986.
No. 41005.

The data input / output device described in this publication is a device for storing a code signal input from a keyboard in a memory and displaying characters corresponding to the code signal on an output device. A control circuit having a code signal conversion circuit for converting a code signal corresponding to a particular key group into a code signal corresponding to a key on the left of each key, a buffer memory for storing the input code signal, and an output And a display device as a device.

The code signal conversion circuit is provided with a conversion table having information on the character / code signal of the corrected character to be converted and the character / code signal of the converted character corresponding to the key on the left side thereof.

When an incorrect character is input by performing a key input with a blind touch in a state where each finger of the right hand of the operator is shifted to the right by one key from the home position, if the wrong character is input, the character input from the keyboard is incorrect. Is corrected as follows.

When the operator designates a display character to be converted displayed on the display device by a predetermined method, the code signal conversion circuit operates the code signal of the specified display character and the correction character arranged in the conversion table. The code signal of the display character stored in the buffer memory is sequentially converted into the code signal of the conversion character corresponding to the correction character, and the code signal of the conversion character is converted. Output sequentially to the display device. As a result, display characters erroneously input and displayed are sequentially corrected and displayed to the characters of the correct character key located on the left side.

[0009]

The conventional data input / output device for converting and displaying the erroneously input character to the character of the correct character key by a simple operation has the following problems. I was

The first problem is that when data is input from the keyboard by blind touch, if the finger is shifted left, up, or down from the home position, it cannot be converted to correct data. is there. The reason is,
This is because the above-described data input / output device has only a function of converting an input key into a key on the left side, and does not consider conversion on the right side and up / down.

A second problem is that, in order to convert a character code, the cursor is moved to the first position of a character string erroneously input by blind touch, and the conversion position is designated. Special key operations, such as pressing a special key for instructing conversion, are required, which complicates operability. The reason is,
In conventional data input / output devices, it is not possible to determine whether the operator is inputting data by blind touch.To convert the input data to the next key, specify the conversion position and perform conversion. This is because an instruction operation is required.

A third problem is that when the character code of the erroneously input character string is converted to the character code on the left, the character code is converted one character at a time by moving the cursor for each character to be converted. That is, efficient code conversion cannot be performed.

[0013] It is an object of the present invention to convert a character which is erroneously input and displayed on a keyboard in a state where each finger is shifted left and right and up and down from a home position into a character of a correct key by a simpler operation and display it. It is an object of the present invention to provide a data input / output device capable of performing such operations.

Another object of the present invention is to determine that a character which has been erroneously input has been input by a blind touch, so that an operation of designating each character to be converted one by one can be performed without performing an extremely simple operation. It is an object of the present invention to provide a data input / output device that converts a character code into a correct character code collectively only by an operation and enables efficient code conversion.

[0020]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a data input / output device according to an embodiment of the present invention.

Referring to FIG. 1, a data input / output device according to an embodiment of the present invention includes a keyboard 10 serving as an input device.
Key input counting means 11 operating under program control to count the number of key inputs per fixed time;
A key code analysis unit 12, a temporary display unit 13, a key code conversion unit 16, a key code storage unit 15 for storing a key code input from the keyboard 10, a key conversion information table 17, The display device 14 is provided.

The key code analysis means 12 is provided for the keyboard 1
The key code generated by the key input using No. 1 is written into the key code storage unit 15, the key code is analyzed and converted into the corresponding kana or kanji, and the converted data is not displayed by the temporary display unit 13. It is displayed on the display device 14 as fixed temporary data.

When the key code analyzing means 12 detects that the kana-kanji conversion key has been continuously pressed a predetermined number of times, the key code analyzing means 12 further calculates the number of key inputs per fixed time counted by the key input counting means 11. If the count value is equal to or more than the predetermined number, it is determined that the input has been performed by the blind touch, and the control is shifted to the key code conversion means 16.

That is, in the present embodiment, the transition to the key code conversion mode for the input key is instructed by continuously pressing the kana-kanji conversion key a predetermined number of times or more. Judgment as a blind touch input is a key code conversion start condition.

The number of consecutive presses of the kana-kanji conversion key is preset to a value such as "3". Also,
The criteria for determining a blind touch input are set in advance, for example, to three or more per second.

The key code conversion means 16 searches for a key input with the right hand (or left hand) by referring to the key conversion information table 17 in accordance with an instruction from the key code analysis means 12, and finds a key on the right (or left). All keys are converted to the keys on the upper and lower neighbors at once.

FIG. 2 is an explanatory diagram showing the arrangement state of each key on the keyboard 10 and which of the right and left hands is pressed when a key is input by a blind touch at the home position. Here, a range 21 indicated by "left" and a range 23 indicated by "right" indicate key ranges pressed by the left and right hands, respectively. In addition, "center (R /
L) "indicates a range in which both the left hand and the right hand may be pressed.

As shown in FIG. 3, the key conversion information table 17 indicates, for each data key 31 arranged on the keyboard 10, whether the normal operator determined based on FIG. Input information 32 indicating
(Left / right / center (L / R)) and converted character key information 33 indicating keys located on the keyboard on the left, right, upper and lower sides. This key conversion information table 17 is written in a storage device such as a read-only memory or a disk.

Next, the operation of the data input / output device configured as described above will be described in detail with reference to FIG.

When a key is input from the keyboard 10 (step 401), the key code analysis means 12 checks whether or not the kana-kanji conversion key has been pressed (step 402). If the kana-kanji conversion key is not pressed, key analysis (keyword conversion into Japanese) of the key data input by the key code analysis means 12 is performed (step 4).
06), the analyzed characters are temporarily displayed on the display device 14 in an undetermined state by the temporary display means 13 (step 40).
7).

Thereafter, if there is a confirmation instruction from the operator (step 408), the temporarily displayed characters are decided (step 409). If there is no confirmation instruction, key input is continued at step 401 without confirmation.

When the kana-kanji conversion key is pressed,
The key code analysis means 12 checks how many times the kana-kanji conversion key has been continuously pressed (step 403).

If the number of consecutive presses of the kana-kanji conversion key is equal to or less than the set value, key analysis (conversion from kana to kanji) is performed by the key code analysis means 12 in step 406.

In step 403, if the number of consecutive presses of the kana-kanji conversion key is equal to or greater than the set value, the key input counting means 11 refers to the number of key inputs per fixed time counted / stored, and If the number of inputs is equal to or greater than the predetermined number, it is determined that a key input has been made by blind touch (step 404), and the key code conversion means 16 is instructed to convert the key code.

In the key code conversion means 16, of the key codes stored in the key code storage unit 15, the key input by the right hand (the input information 32 of the key conversion information table 17).
Is the key 31 which is “right” and “center”, the key is referred to the “right neighbor” (or “left neighbor”, “upper neighbor”, “ Below) "
(Step 40)
5). Similarly, if the key is a key input with the left hand (the input information 32 of the key conversion information table 17 is the key 31 that is “left” and “center”), the information of the key conversion information table 17 is referred to and the key is changed to “ Right next ”(or“ left next ”,“ top next ”,
Batch conversion into the conversion character key 33 of "lower neighbor" is performed.

The key data after the key code conversion is analyzed (such as kanji conversion) (step 406), and the analysis result is temporarily displayed on the output device 14 (step 407). Thereafter, if there is no confirmation instruction (step 408) and the kana-kanji conversion key is further input, it is determined in step 403 that the value is equal to or greater than the set value, and in step 404 it is determined that the input is a blind touch. A different conversion from the previous one is performed.

For example, if the previous conversion is a batch conversion of a key input with the right hand to a conversion character key of "right next", a batch conversion of a key input with the right hand to a conversion character key of "left next" is performed. Done. Similarly, when the kana-kanji conversion key is further input, another conversion is performed in step 405.

The order of the conversion in which the key code conversion is performed in step 405 is set in the key code conversion means 16 in advance. For example, the first time is input information 3
2 The “right” key is the “right next” converted character key, the second is the input information 32 “the right” key is the “left adjacent” converted character key, and the third is the input information 32 “left” key Is set to be converted to the conversion character key on the “left side”. If the conversion order is set in this way, the conversion contents are switched each time the kana-kanji conversion key is input.

Next, a specific operation of the data input / output device of the present invention will be described with reference to FIG. Here, for example, it is assumed that data is input by inputting “red flower” and Roman characters. Further, the key analysis means 12 shifts to a key conversion mode for correcting a key shift when the kana-kanji conversion key is continuously input three or more times, and the key input counting means 11 outputs the key input mode three or more times per second. It is determined that the key input by the operator has been performed by the blind touch when the key input of the key is counted.

It is assumed that the operator's right hand is shifted to the left by one key from the home position when making a key input on the keyboard 10. If both hands were correctly placed at the home position, the place where "AKAIHANA" was input in Roman characters, but "AJAUGABA" was input because the right hand was shifted to the left by one key.

When the first character "A" is input, it is not a kana-kanji conversion key, so that key analysis (kana conversion) is performed by the key code analysis means 12 in step 406.
"A" is temporarily displayed on the screen (step 407). Here, if the second character "J" is input without the confirmation instruction, the key analysis is performed in step 46 because the key is not a kana-kanji conversion key, and "AJ" is temporarily displayed on the screen. It is displayed (step 407).

When the third character "A" is input, it is analyzed together with the second character "J" in step 406, and is analyzed.
"Aja" is temporarily displayed on the screen (step 407).
In the same manner, "Ajaguba" is temporarily displayed on the screen in the same manner.

At this time, the operator notices an input error,
When the Kana-Kanji conversion key is pressed three times in succession, the first and second Kana-Kanji conversion keys are pressed.
Then, the process proceeds to step 406, where the analysis (kanji conversion) is performed, and the analysis result is provisionally displayed in step 407.

By operating the kana-kanji conversion key for the third time, the process proceeds from step 403 to step 404, and it is determined whether or not three or more key inputs are made per second by referring to the count value of the key input counting means 11. Check (step 404). If three or more key inputs are made per second, it is determined that the input is a blind touch input, and step 4 is performed.
The process proceeds to the key conversion process 05.

In step 405, first, all the keys (keys corresponding to "right" and "center" in the input information 32) input by the right hand are collectively converted into converted character keys corresponding to "right next".

More specifically, based on the key data (AJAUGABA) stored in the key code storage unit 15, a key input by the right hand, that is, a key conversion information table 17
Is searched for a key whose input information 32 is "right" and "center", and is converted into a key stored in the "right neighbor" of the converted character key 33 at once.

In this specific example, "J", "U", "
The input information 32 of “G” and “B” is “right” or “center”, and these are respectively input to the “right” keys “K”, “I” and “
By converting the data into "H" and "N", the key data is converted into the key data "AKAIHANA" to be originally input, and in step 406 "Japanese red" is converted into Japanese and temporarily displayed on the screen. When the operator determines that the conversion has been correctly performed by looking at the temporarily displayed characters, the operator instructs confirmation, and the conversion is completed.

If the desired data is not obtained by one conversion, the Kana-Kanji conversion key is pressed again to convert a key entered with the right hand to a key located on the “left side” or with the left hand. The entered key is converted into a key located on the “right side” or “left side”.

When converting a key input with the right hand to a key on the right side, the input information 32 of the key conversion information table 17 is changed from the key "right" or "center" to the key "right next" of the conversion character key 33.
Convert to the key stored in. Similarly, when converting to the key on the left, the key on the “right” is converted to the key on the left, and when converting to the key on the upper and lower sides, the keys on the “right” and “center (R)” are changed. Convert to the key "upper neighbor" or "lower neighbor".

When a key input with the left hand is converted into a key on the right, input information 3 in the key conversion report table 17 is used.
2 converts the "left" key into a key stored "right next" to the conversion character key 33. Similarly, when converting to the left adjacent key, the "left" or "center" key is converted to the "left adjacent" key, and when converting to the upper and lower adjacent keys, "left" and "center (L)" Is converted to an “upper neighbor” or “lower neighbor” key.

In the above embodiment, the key code conversion mode is entered when the kana / kanji conversion key is continuously pressed a predetermined number of times or more. However, a special key for key code conversion is used. , And by pressing the key code conversion key, the mode can be shifted to the key code conversion mode. The operation in this case is shown in the flowchart of FIG.

In FIG. 5, when a special key code conversion key is pressed (step 502) and it is determined that the input is a blind touch input (step 503), a key code conversion process is performed (step 504). The processing in other steps is the same as each step in FIG.

Next, a second embodiment of the present invention will be described with reference to FIG. In the data input / output device illustrated in FIG. 6, a conversion order information storage unit 50 that stores conversion order information indicating a key code conversion order is added to the configuration illustrated in FIG. The other components are the same as those shown in FIG. 1 and will not be described.

The conversion order information storage unit 50 is constituted by a rewritable storage device, and a key input by either hand at the time of key code conversion ("right neighbor", "left neighbor", "upper neighbor"). , And "lower neighbor"), the conversion order information indicating the priority in which the conversion is performed is stored. When a key code conversion instruction is given, key code conversion means 1
Reference numeral 6 refers to the information in the conversion order information storage unit 50 and executes the conversion of the key code in accordance with the conversion content having the higher priority.

By providing the conversion order information storage unit 50 for storing such conversion order information, if conversion order information is created and stored in accordance with the habit of key input by the operator, more efficient operation can be achieved. Batch conversion of key codes becomes possible.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments.

[0057]

As described above, according to the data input / output device of the present invention, first, even when the finger is shifted left or right or up and down from the home position when inputting data from the keyboard by blind touch. Thus, there is an effect that the data can be collectively converted into correct data without re-inputting. The reason is that, for each key, input information indicating which hand is to be used for input, and converted character key information of the keys located on the left, right, up, down, and right for each key are set as a table, and the table is referred to collectively. This is because conversion has been made possible.

Second, characters which have been erroneously input by a simple operation of simply pressing a specific key can be collectively corrected to a correct character without performing a troublesome operation such as specifying each character to be converted one by one. Efficient code conversion to code conversion is realized. The reason is that it automatically determines whether or not data is being input by blind touch, and in the case of blind touch input, converts key shifts in a batch by a very simple operation of pressing a specific key. Because we made it possible.

Third, erroneously input characters can be collectively converted into a correct character code by the same operation as a normal kana-kanji conversion instruction, so that more efficient code conversion can be performed.
