Description

[0001] The present invention relates to a key character key spacing control method,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for preventing a typographical error occurring when a character is input through a keyboard on a touch screen, and more particularly, &Lt; / RTI >

Various kinds of portable communication terminals have been developed in order to provide wireless communication in which various information is supplied in real life as industrial technology is developed.

In an initial portable communication terminal, a keypad for inputting characters and a liquid crystal screen for outputting characters are separately provided. When a user presses a character input button formed on a keypad, characters are input in a manner that characters are displayed on a liquid crystal screen.

However, as a touch screen technology in which a keypad function is simultaneously output on a liquid crystal screen has been commercialized, a portable communication terminal equipped with a touch screen has become widespread. Also, various types of computer terminal devices other than a portable communication terminal, Devices are being applied gradually.

In addition, since the communication terminal is designed to be small in size in order to allow the user to easily carry it in the case of the touch screen mainly used in the portable communication terminal, a plurality of input buttons constituting the keypad outputted to the touch screen are formed in a small size .

However, in the case of a touch screen applied to a portable communication terminal, since the input button of the keypad is formed in a small size, when the sensing means is different from the contact means contacting the input button and the user's skill level There is a problem that a touch signal is applied to an input button adjacent to the specific character on the keypad instead of an input button of a specific character to be input by the user.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for correcting a typo caused by erroneous touch of an adjacent character key by adjusting a character key interval on a keyboard displayed on a touch screen .

According to an aspect of the present invention,

A keyboard character key spacing adjusting method for improving a typographical error caused by erroneously touching an adjacent character key when a character is input using a keyboard displayed on a touch screen,

A typing occurrence determining step of determining whether or not a typo is generated in a character input through the keyboard;

If it is judged that an error has occurred in the erroneous erroneous judgment process, the interval between the character key (erroneous character key) corresponding to the character with the erroneous character and the character key (erroneous character key) corresponding to the erroneous character A clear key interval adjustment process for adjusting a clear key interval;

And a control unit.

Here, if the input character is deleted by the delete key, and then a new character is input, the character key corresponding to the deleted character and the character key of the newly input character are compared with each other on the keyboard Or not.

Here, the character key interval adjustment process adjusts the clearance interval according to the frequency of occurrence of a typo for the corresponding otal character key.

Here, in the character key interval adjustment process, in addition to adjusting the clearance interval in correspondence with the frequency of occurrence of a typo for a corresponding typewriter character key, in addition to the occurrence of the typewriter character key and the typewriter character The positions of the remaining character keys except for the key are shifted to the opposite side margins by an interval corresponding to the margin margin.

The keyboard character key spacing adjusting method according to the present invention improves the error caused by erroneously touching an adjacent character key by adjusting a character key interval when an error occurs due to an adjacent character key on a keyboard displayed on a touch screen .

FIG. 2 is a flowchart illustrating a method of adjusting a keyboard character key interval according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view illustrating a method of adjusting a keyboard character key interval according to the present invention.

FIG. 1 (a) shows a conventional arrangement of a touch key character key.

The touch keyboard 100 shown in FIG. 1 may be displayed on a touch screen (not shown) to accept a character input by a touch.

(a), the touch keyboard 100 includes a plurality of character keys 102 arranged in a matrix, and a margin 104 is formed on both sides of each row.

(a), the alphabet key 106 and alphabet key 108 are arranged with an interval of t, and the margin 108 has an interval of b.

it is assumed that an error has been generated by the 'h' character key 106 and the 'ㅗ' character key 108 in FIG. For example, supposing that the user inputs a character 'heh', the character key 108 is mistakenly touched to touch the character key 108 instead of the character key 106. In this case, 'ㅎ' is referred to as a typographical character, and 'ㅗ' is referred to as a typographical character. A typographical character is a character that can not be properly input due to a certain winin, mainly a wrong touch. On the other hand, the ota induction character is a character which is mistakenly touched due to a habitual factor, and which is to be deleted by a delete key and replaced by a correct character.

(b) and (c) show the states in which the character key interval is adjusted in the occurrence of the error, (b) corresponds to the case where the occurrence frequency of the error is low, and (c) corresponds to the case where the occurrence frequency of the error is large.

(here, the character key 106 corresponding to the omitting character (here) and the character unit corresponding to the ota causing character (here, character corresponding to the character here) in the case of (b) and (c) (T2> t1) in the case of (c) is larger than that in (b), that is, the frequency of occurrence of the error It can be seen that the interval between the character key corresponding to the typed character and the character key corresponding to the typed character (hereinafter referred to as the clearance interval) is widened.

On the other hand, in the case of (b) and (c), the margin interval is adjusted, and the position of the other character keys in the row to which the typed character key and the typed character key belong are also moved toward the edge. 104 are adjusted (b2 > b1).

FIG. 2 is a flowchart illustrating a method of adjusting a keyboard character key interval according to the present invention.

Referring to FIG. 2, the method of adjusting the keyboard character key interval according to the present invention includes a key generation determination process S202 and a key key interval adjustment process S204.

Here, if a character inputted through the keyboard is deleted by a delete key and then a new character is inputted, a character key corresponding to the deleted character and a character key corresponding to the newly inputted character are displayed on the keyboard It is determined whether or not these keys are adjacent keys.

Erroneous characters are erased by the delete key and replaced with the correct characters. Accordingly, by detecting the operation of the delete key and the input of a new character thereafter, it is possible to determine whether or not an error has occurred.

However, there is a need for a method to judge this by deleting by deletion key and then inputting a new character to be executed, not necessarily for correction of typo (for example, when erasing an unwanted phrase and writing new one) Do.

In the present invention, when a new input is performed immediately after deletion and deletion among adjacent character keys on the keyboard, it is judged that a typo caused by the adjacent character key has occurred. This determination method is suitable for most typos that occur when a character is input using a keyboard displayed on a touch screen.

That is, when the adjacent character keys are erroneously input due to the thickness of the finger, the angle formed by the finger and the touch screen when the finger is touched on the touch screen, and not the correct character keys, The new character will be input by touching the character key next to the character key corresponding to the erroneously input character (typographical character key).

In the present invention, in order to correspond to a typo generated by the adjacent character keys, the possibility of typing is reduced by adjusting the interval between the adjacent character keys, i.e., the typed character key and the typed character key.

In addition, the interval between the typed character key and the typed character key is adjusted, and the position of the other character keys in the line to which the typed character key and the typed character key belong are shifted to the opposite sides to further reduce the possibility of typing .

In the key key interval adjustment process S204, if it is determined in step S202 that an error has occurred due to the adjacent character key, the interval (clearance interval) between the typed character key and the typographical character key is adjusted.

The adjustment of the clearance interval is as shown in FIGS. 1 (b) and 1 (c).

Here, as shown in Figs. 1 (b) and 1 (c), it is preferable to adjust the clearance interval in accordance with the occurrence frequency of the typographical character key. Here, the occurrence frequency of the typo can take into account the occurrence rate of the typo and the rate of the occurrence of the relative typos.

Here, the consideration of the relative rate of occurrence of a typo refers to performing the adjustment of the key spacing with respect to the highest occurrence rate of the typo when a typo occurs in various places.

Considering the rate of occurrence of a typo means that the character key interval is narrowed when the rate of occurrence of the typo is lowered.

In the character key interval adjustment process (S204), in addition to adjusting the clearance interval in accordance with the occurrence frequency of the misfit for the corresponding misfit character key, in addition to the misfit character key and the misfit character It is preferable to move the position of the remaining character keys except for the key to the both side margins by an interval corresponding to the margin margin.
