Abstract

PURPOSE:To eliminate the manhours for checking and also, to decrease key input errors, and to prevent malfunction and abnormal operation of the system caused by the key input error by collating the input by a key to an error pattern until now at the time of key inputting, then raising warning. CONSTITUTION:The system is constituted of an input error deciding means (steps S1-S4) for checking a key input by referring to an error pattern storage part 4, and correcting automatically a correction instruction if any, a key input change history storage means 2 (steps S5, S6) for storing a change history in a change history storage part 5, when the key input is corrected, and an error pattern detecting means 3 (steps S7, S8) for monitoring the change history storage part 5 and registering an error pattern in the error pattern storage part 4, when the same change history reaches the prescribed number.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key input checking system, and more particularly to a key input checking system for checking and warning of key input errors that are likely to occur due to incorrect key presses.

0002

[Prior Art] Conventionally, in most cases, information indicated by key inputs from a keyboard (character codes, etc.) is passed to an information processing system without any checking, and is judged and processed as is. . Some information processing systems have a built-in process that converts key input (for example, Japanese conversion), and it functions as a check to ensure that if there is a mistake in key input, it will not be converted. Input is not checked.

[0003] There is also a method of determining whether a key input is appropriate for an information processing system by performing a numeric check or a limit check. For example, in the numeric check, it is checked whether the key input is a number or not, and if it is not a number, a warning is issued and the user is prompted to re-enter the key. In the limit check, it is checked whether the key input is from a specified range of keys, and if the key is outside the range, a warning is issued and the user is prompted to re-enter.

However, the numeric check is only applicable when the input is a number, and the limit check is only applicable when the input is limited to a specific key. Therefore, the only way to check when accepting unspecified key inputs is to display the input key input information on a screen and visually check it, or to print it out and then visually check it.

[0005]

[Problems to be Solved by the Invention] As mentioned above, conventional key input checking methods generally display the results of key inputs on the screen, except when limited to a specific range or application. Since this method relies solely on human intervention, in which the process is checked visually, there are many oversights, resulting in system malfunctions and a large loss of time required to perform the process again.

[0006] An object of the present invention is to provide a key input check method that can generate a warning for key input errors and also perform automatic correction.

[0007]

[Means for Solving the Problems] The key input check method of the present invention includes key input change history storage means for storing a history of changes in a change history storage unit when a key input is modified; An error pattern detection means that registers an error pattern when the same change is stored a predetermined number of times, and an input error detection unit that compares key input with the error pattern and generates an alarm when it matches, and corrects it if instructed. and means.

[0008]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a flowchart showing the processing procedure of an embodiment of the present invention.

The key input check method of this embodiment is shown in FIG.
As shown in the figure, the input error determining means 1 consists of steps S1 to S4, and checks and corrects the key input by referring to the error pattern storage section 4, and the step S5 and S6 consists of the input error determination means 1, which checks and corrects the key input by referring to the error pattern storage section 4, and includes steps S5 and S6, when the key input is corrected. It consists of a key input change history storage means 2 that stores the change history in the change history storage section 5, and steps S7 and S8.The change history storage section 5 is monitored, and when the same change history reaches a predetermined number, it is recognized as an error pattern. and an error pattern detecting means 3 which is registered in a pattern storage section 4.

When a key input is performed, the input error determining means 1 first temporarily stores the key input in a memory in step S1. This memory holds a fixed number of multiple key inputs in the order in which they were input. Next, in step S2, the stored key input string is compared with the error pattern registered in the error pattern storage unit 4, and it is determined whether the input key input string matches the error pattern. For example, in step S3, a warning is issued to the person who inputs the key. The warning may be issued by, for example, making a buzzer sound and highlighting the erroneously input characters on the display. On the other hand, when the key input person presses the correction key, the highlighted character is automatically corrected according to the error pattern in step S4. Therefore, the key input user does not need to return and correct the cursor position, and can continue to input the next key.

The key input change history storage means 2 stores the change history in the change history storage section 5 when a key input that has already been input is changed by a key input person. First, in step S5, it is determined by returning the cursor, and if there is a correction, in step S6, the key input strings before and after the correction are stored in the change history storage unit.
Store in. The target key input string is basically between two spaces, that is, one word. Note that what can be stored as a change history is limited to those that are within the range of the memory where the return for correction was previously stored in step S1.

The wrong pattern detection means 3 constantly monitors the change history storage section 5, and when the same change history reaches a certain number, it extracts the change history as an error pattern and registers it in the wrong pattern storage section 4. do. In principle, one word unit separated by a space is registered as an error pattern, but character strings shorter than one word including correction characters may also be extracted that have a certain number of characters or more.

[0014] For example, an inputter inputs "if" from the keyboard.
I mistakenly entered "ib" instead of "if" and then "if".
If the corrections are repeated, "ib→if" is registered in the error pattern storage unit 4 as an error pattern. If you make a similar input error next time, a warning will be issued when a space is entered after "ib" and "ib", the letter b will be highlighted and you will be asked to correct it. If the inputter is “ib”
” is a mistake in “if” and the correction is accepted, it is automatically corrected to “if”. This eliminates the need for the inputter to move the cursor back and input the correction, making it easier to overlook input errors. It is possible to prevent this and reduce the number of man-hours required for corrections.

[0015]

[Effects of the Invention] As explained above, the key input check method of the present invention compares the key input error pattern with the previous key input error pattern and issues a warning. It is possible to reduce input errors and has the effect of preventing malfunctions and abnormal operations of the information processing system due to key input errors.
