Description

[0001] The present invention relates to a QWERTY keypad, and more particularly,

The present invention relates to a QWERTY keypad to which a method of increasing the recognition accuracy according to the frequency of use of a key is applied. More particularly, the present invention relates to a QWERTY keypad, which includes (1) 2) "Analyze the characters entered by the user through the keypad and then calculate the probability through the frequency analysis matrix of the letter" and apply it to the keypad.

In particular, the present invention does not make a large difference in appearance from the conventional QWERTY keypad, and uses the frequency analysis table and the frequency analysis matrix of the first and second embodiments to create probabilities for the next key, And a method of increasing recognition accuracy by enlarging a shape and a recognition area of a corresponding high probability key in a line not influenced by another key.

BACKGROUND ART [0002] With the development of electric, electronic, computer and communication technologies, the use of smart phones is rapidly increasing in living with electronic devices. So it is the smartphone that can not be missed in all life. Smartphones are replacing every aspect of life and are expected to replace them in the future.

To use such a smartphone, it is necessary to transmit the input to the smartphone using an application called an application. The part receiving the input is constituted by dialing the keypad, and the shape of the keypad receiving the input is different for each communication device company.

(Patent Document 0001) 1. Korean Patent Laid-open Publication No. 10-2014-0112430 discloses a keypad for inputting four input characters vertically and horizontally, This reduces the likelihood of errors in keystrokes and increases the accuracy of key recognition. However, since the interface is different from the QWERTY keypad used in the past, the speed of input by the unfamiliar user is lowered.

(Patent Document 0002) 2. Korean Patent Registration No. 10-1249329 discloses a keypad for converting and inputting different characters due to a plurality of pressing of a key, and a small keypad implemented in a limited- . As in Patent Document 1, although the key recognition accuracy is improved through the modification of the keypad, there is a problem in that the improved part is not meaningful because it leads to a decrease in the input speed of the unfamiliar user due to the difference between the configuration and the interface with the existing QWERTY keypad Lt; / RTI >

(Patent Document 0003) 3. On the keypad circle for inputting the English sentence of Korean Patent Registration No. 10-1312875 and setting the priority order in descending order of occurrence frequency in units of English words after inputting and predicting the words In this paper, we propose a method to predict and translate English words in English. In this paper, we propose a method to predict English words in English. The problem is that the prediction is delayed, that it is applied to the existing mobile device, not the smartphone, and that the computer memory is much used because it is predicted only in English and the size of the storage for storing the priority is large.

1. Korean Patent Publication No. 10-2014-0112430 2. Korean Patent Registration No. 10-1249329 3. Korean Patent Registration No. 10-1312875

In order to improve the accuracy of the keypad of the smartphone, the present invention has been developed to solve the problems of the related art as described above. In order to increase the accuracy of the keypad of the smartphone, Display using finger When inputting touch input, it is used to store the probability information while changing the frequency probability of the key, so that the recognition accuracy is higher than that of the conventional keypad.

In addition, the present invention aims at maintaining the input speed improvement according to the user's familiarity and improving the key recognition accuracy by using a QWERTY of a familiar shape, rather than a complete modification of the keypad shape which is common to the existing patent documents.

In order to achieve the above object, the present invention has three components.

(1) operate the existing smartphone QWERTY keypad software as basic software,

(2) The probability of using the first, middle,

(3) Consistent with the usage probability of each consonant and vowel key obtained through the matrix obtained through the program analyzing the frequency of use information of each next key of the keypad used by the user, the physical recognition range of the keypad on the existing QWERTY keypad And the keypad shape is enlarged.

In the above (2), the "use frequency table of the Korean, English, and Korean characters used in the information retrieval" is based on the average frequency of Korean web pages, It is an informative table that obtains the probability of the middle and the end, and becomes an auxiliary means.

The matrix (3) obtained through the program for analyzing the frequency-of-use information of each of the following keys of the keypad used by the user is the main means of probability used to expand the N keys corresponding to the probability .

In addition, the configuration of the seconds, middle, and consonants used in the means of (2) and (3) presented above is composed of keys existing in the QWERTY keypad, and consonants are terminal sounds, ㄸ,, ㅎ, ㅎ and ㅎ, ㄸ, ㅃ, ㅆ, ㅉ and total vowels are short vowels and double vowels, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ, ㅠ (33) and (33) 33 matrices consisting of 33 (33) and (33) 33 matrices consisting of (1) and (2) (terminal sound + double consonant + short vowel + The element is characterized by a probability.

As an embodiment of the present invention, when the user inputs the shape of the keypad, the existing QWERTY keypad is used as it is, and the difference is obtained by integrating the means (2) and (3) N is extracted so that the number of keys on the keypad does not exceed the area of the other key, thereby showing the extent of the physical recognition area of the smartphone electronic device and the change in the expansion of the keypad key.

The present invention can be applied to a conventional QWERTY keypad by analyzing (1) "Korean alphabet consonant used in information retrieval, use frequency table for each character of a vowel" (2) "character inputted by a user through a keypad, One matrix "to calculate the probability of the next character. The smartphone keypad, which predicts the next character and increases the accuracy of the key by increasing the recognition area of the key so that it does not exceed the key of the other character .

Since the interface is configured using the existing QWERTY keypad, the probability of typos that can be pushed to another key due to the small size of each key is prevented from being confused with the user's viewpoint. The number N of keys to be increased to the next key by the number N of keys to be enlarged set by the user is enlarged to indicate the shape of the key, so that the error rate can be reduced.

And since the smartphone users who use a small display are provided with the next all-key enlargement, it is possible to see the key I want to input in a quick and detailed way.

Since the prediction unit is not a word but a collection key unit, it is possible to predict the input before completion of the input more than one word, It has the effect of saving computer memory when implementing base storage.

In particular, since the key to be used by the user can be seen first through the prediction keys provided by the present invention, such as the auto-completion technique or the related keyword search technique used in the Internet portal site, only the N expanded keys are searched So that the time is shortened.

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.

The drawing of the present invention relates to a configuration of a QWERTY keypad (FIG. 1) responsive to an actual key input, a basic view of the QWERTY keypad (FIG. 2) For example,

In order to carry out the internal function of the present invention, it is necessary to analyze the characters used by the user through the keypad, such as "usage frequency analysis table for each Korean character consonant and vowel used in information search" And the table for analyzing the frequency of the next letters "(FIG. 5)

In the final configuration, the flow chart of the keypad initialization, input and termination processes of the present invention is shown in FIG. 6.

In the description of the present invention, the basic configuration of the QWERTY keypad (FIG. 2) constitutes the present invention, but the difference is that when the input is received through the touch display, the probabilities of FIGS. A point where a high probability key is enlarged and applied to the corresponding key of the keypad,

And is used internally to analyze the user's keypad input habits and to enlarge the keypad with the necessary probability for the next all-key per user. It should be understood, however, that such expressions are not intended to limit the scope of the present invention to a single keypad, but to all keypads to which the principles are applicable.

As shown in FIG. 2, the character key is basically in response to a basic QWERTY keypad as shown in FIG.

The features of the present invention are listed as follows.

1) Do not use existing QWERTY keypad to confuse users.

Since the existing QWERTY keypad configuration is used as it is, there are advantages that are different from other keypad inventions.

When the configuration environment is changed, there is a disadvantage that the user has to adapt and recognize the keypad according to the environment of the keypad, and to master the usage method, and there is a disadvantage that the probability of typo is increased and the input speed is lowered. However, Can be advantageous in that it does not confuse input.

2) By marking the next key, it is possible to see and input correctly.

Using the table in Figs. 2 and 3, we predict the key following the input key because we have a probability. From the user's point of view, it provides an environment that can quickly input even a few keys.

The principle of probability will be described below after explaining all the features of the present invention.

3) Provide large keys to users with poor eyesight and those who are not skilled at typing.

For users with poor eyesight and lack of proficiency in input, the use of the conventional QWERTY keypad is a small key, so it is necessary to input one by one when inputting. However, a small keypad causes a decrease in input speed. I did not use the QWERTY keypad because I use a keypad with a different shape of the shape. In order to solve this problem, the convenience of the user is provided by expanding the next key.

4) Improve the lack of key recognition accuracy on small display smart phones.

If the smart phone is small, the display is also proportionally smaller. And because the physical condition of the user (for example, large-handed users) is disadvantageous to the input, there may be inconvenience to the user using the small display. This problem is solved by enlarging the recognition range as much as the recognition range of the key predicted by the present invention and the recognition range of the key that is not predicted beyond the recognition range of the unexpected key, It provides convenience for users who use small smartphones and small keypads to lower key mislabeling and improve recognition accuracy.

5) Prediction through the control unit The number of representations N of the next key to be represented can be selected and updated via a document containing user-written text when desired.

Since the number of expressions N of the next key to be predicted can be selected by pressing the control unit, it is possible to select the number of keys to be expressed by pressing and pressing. Therefore, The probability of the predicted key can be updated according to the input habit of the keypad created by the user.

The configuration of the present invention consists of a three-part character key, a function key and a control key using a QWERTY keypad as a basic configuration. The character key is composed of a Hangul character provided by a QWERTY keypad. A key for inputting special characters and symbols, a number of predictable characters N, a control key for updating the prediction probability, and a space and an enter for spacing. If you press the Shift key on the corresponding keyboard and short vowel,,,, ㄷ, ㅅ, ㅐ, ㅔ key, the character consonant and the double vowel ㅃ, ㅉ, ㄸ, ㄲ, ㅆ, ㅒ,

In the layout of the basic configuration, a character key is entered from the first line to the third line, the first key on the left side of the third line is the Shift key, the last key on the right side is the Backspace, and the fourth line is the symbol key, Depending on the configuration of Enter, character keys and vowels can be positioned in a total of N rows, with the arrangement being selected through translation in the basic form of the qwerty keypad.

Hereinafter, the process of applying the software to the keypad will be described in time sequence using the configuration and features of the present invention.

As a practical example, a case of inputting "I" as shown in FIG. 1 will be described.

Once "b" is entered, the top N probabilities for the next all key for each letter organized in the internal program are selected.

The principle of selecting N is as follows: (1) "Hangul consonant used in information retrieval, vowel frequency table for each vowel (figure 4) and (2)" The user analyzes the characters input through the keypad, Quot; matrix of frequency analysis of FIG. 5 "(FIG. 5) to obtain N high-probability keys with high probability.

Here, (1) "the frequency of use analysis table for each Korean consonant and vowel in the information retrieval" (Figure 4) is to apply the probability found in the table immediately,

(2) "Describes the principle of analyzing the character input by the user through the keypad to determine the probability of the next frequency matrix of the letter" (FIG. 5). The QWERTY input that the user has used in the past, for example, analyzes the chat with the file of the document or the written document. Suppose the content is entered as "Goodbye". Let 's classify "goodbye" as first, middle, and last. "ㅇ, a, b, b, ㅕ, ㅇ".

In the matrix of FIG. 5, the consonants that can be directly input on the QWERTY keypad are terminal sounds A, B, C, D, K, F, G, Y, G, , ㅃ, ㅆ, ㅉ. The total consists of 14 pieces and the vowels are composed of short vowels and double vowels, ㅑ, ㅓ, ㅕ, ㅗ, ㅛ, ㅜ,,,,, ㅐ, ㅒ, ㅔ, 되어 A 33 * 33 matrix consisting of 33 points (1) and (2) of (terminal sound + double consonant + short vowel + double vowel) is constituted and as shown in FIG. And each element is the frequency of the next key.

Express the process of applying.

Find the column 'a' in row 'ㅇ', increase frequency 1, find column 'b' in row 'a', and increase frequency 1. Likewise, find the column 'b' in row 'b', increase frequency 1, find column 'b' in row 'b', increase frequency 1, find column 'o' in row ' .

The resulting array after the above process is shown in FIG.

With the array thus generated, the probability of FIG. 3 that is different from the probability of FIG. 4 and the probability of FIG. 4, that is, the probability of FIG. 3, is obtained by combining the probabilities at a ratio of 1-n: n (1 means 100% The next key is selected.

Quot; I " as shown in Fig. 1, which is an actual example again.

Based on the probability array generated at the end of the above process, each key is predicted to come to the next N, and the key is enlarged as shown in FIG. (However, assuming that the next syllable of '' (space) 'is not predicted, all keypad letters remain initialized as shown in Fig. 2 until' '(space)' is input.

As described above, the present invention is not limited to the above-described embodiment, and it is also possible to provide a visual effect through enlarging the size of the key of the prediction key corresponding to the probability of each key, even though the input of 33 letters in the QWERTY keypad is not visible The display provides an enhanced QWERTY keypad interface with physical effects that increase the recognition probability by widening the physical recognition range to the same extent as the expanded keypad key.
