Description

Text Input Device in Mobile Phone {.}

The present invention relates to a proposed character input device in order to overcome the difficulty in entering characters due to the limitation of the number of buttons in a small device such as a mobile phone, and forms a basic form in the consonants and vowels of Korean characters, numbers and alphabets of English. After extracting a few basic sentence forms, it is possible to input the whole character by combining only the basic sentence forms, so that the input unit is composed only of the basic sentence forms. The present invention relates to a character input device using a basic sentence type for inputting a character.

In modern times, information communication devices such as mobile phones, pagers, small game consoles, and remote controllers are becoming smaller, and the number of input buttons is decreasing. However, as the function is improved in inverse proportion to the reduction in size, the necessity of inputting characters continues to increase. Therefore, because it is necessary to input several characters such as Korean, Arabic numerals and English with the limited input button, assign several characters to one button, and when selected, press it continuously to select the character and then press the cursor to input the next character. In order to overcome this problem, the present invention provides a basic sentence form that can best represent them from basic characters (Korean: consonants, vowels, English: alphabets, Arabic numerals, etc.). By extracting and reconstructing the characters by combining the basic sentence types, the character input device that can easily input all the numbers by sequentially inputting the basic sentence types as in a computer keyboard even with a limited input button (for example, a mobile phone). To propose.

For example, a mobile phone, which is a small, generalized product using a Korean input device, is described. For example, since only 10 text input keys are used, a plurality of consonants, vowels, and alphabets must be assigned to a single button. Therefore, the user selects one consonant, vowel, or alphabet to be input from the button and presses the button as many times as necessary to select one letter, then moves to the next space with the cursor movement key and selects the next letter in the same way as above. do. This method is very inconvenient because the user does not input the characters, but combines the characters one by one, making it difficult to input a large amount of characters because the input method is difficult and cannot input Korean and alphabet simultaneously. Character input is very inconvenient. In order to overcome this problem, each mobile communication company provides a text service. When the sender calls the operator and calls a character to be transmitted, the operator enters the text and receives the receiver.

In the mobile phone products of the parent company, we are trying to improve the efficiency of text input by adopting the input method of "Cheon, Ji, In", but this is also applied only to Korean vowels. Since it is necessary to input three times and the consonants are used as they are, there is no significant progress compared to the conventional input method.

Example of entering Korean vowels of a parent company

In case of inputting as above, in case of ㅑ, ㅕ, ㅛ, ㅠ, only one vowel should be pressed, and the cursor movement button must be pressed to input the next character.

The present invention proposes a Korean character input apparatus capable of inputting consonants, vowels, and numbers of Korean characters as a limited input means (for example, the number of input buttons) to overcome the above problems.

Therefore, the present invention proposes to extract a basic sentence type that can best represent the character from each basic character to input the Hangul with a limited input means (for example, a button), and only one basic sentence type is independent of each input button. By assigning to, it is proposed to arrange the input buttons so that the basic characters can be continuously inputted by sequentially pressing the buttons. In addition, the present invention forms a basic character (consonant or vowel) by combining the basic sentence in two in order to automatically recognize between the character and the character, a character input device that can be sequentially input characters without moving the cursor Suggest. In addition, the present invention proposes an arrangement of buttons for inputting Korean characters with a minimum combination of buttons by applying these character input devices to a mobile phone, and proposes a character input device capable of effectively inputting the above characters.

2-Configuration diagram of a character input device using a basic sentence

The configuration of the present invention is a basic sentence type extracted from a basic character (consonants and vowels of the Hangul), an input unit for inputting the basic sentence type, a character recognition unit recognized as a character as the input basic sentence, output to output the recognized character It consists of wealth. Since the input unit, the character recognition unit, and the output unit are almost similar to the functions of the input unit, character recognition unit, and output unit of the conventional character input apparatus, the description of the above parts is omitted, and the configuration of the basic sentence form which is a characteristic part of the present invention. And the relationship between basic sentence and basic character and character conversion relation.

First, the basic sentence extracted for each basic character and the combination of the original basic character are as follows.

Our Hangul consonants consist of a, b, c, d, k, k, k, k, k, k, k, k, k, h, vowels, k, k, k, k, k, k , TT, ㅠ, ㅡ, ㅣ, By suggesting a basic sentence type that best represents the consonants and vowels, and combining the two basic sentence types, a device for inputting basic characters is proposed.

Table 1 describes the contents of entering Korean consonants and vowels using basic sentences. In addition, it can be changed into various forms through the transformation and combination of basic sentences that can represent consonants and vowels.The basic sentence patterns can be extracted from the consonants and vowel forms, and they are combined twice to form consonants and vowels. It is to be included in the technical idea of the present invention to construct a character in the form as in 1).

Hereinafter, an input unit for inputting the basic sentences will be described. The input unit may be input by a hand or in various ways, and may also be various in kind, push, touch, click, hitting, etc. In the present invention, only the push type is mentioned, but the rest of the touch type is also applied. There will be no difficulty.

1 illustrates an example of button arrangement of a keypad related to an input device to which a basic sentence pattern is applied to a mobile phone. Figure 1. How to input Korean in Table 1 The consonant input unit and the vowel input unit are separately shown to distinguish the input of the consonant and the vowel. In Fig. 1, the consonant input unit is (1), (2), (3), (4), (5), (6), (8), and the vowel input unit is (5), (7), (8). , (9). (5) and (8) of the consonant input unit and the vowel input unit are configured to be overlapped, but the method of distinguishing is as follows.

-5 or 6 inputted in pairs with 7 or 9: recognized as vowel sentence

5 and 6 inputted in pairs with the consonant input unit: recognized as a consonant sentence type

As described in c) of Table 1, the consonants and vowels are always composed of two basic sentences when the consonants and vowels are inputted using the keypad of Fig. 1, so that characters can be entered as follows.

-In case of 'baby' input : consonants 1 (ㅇ), vowels 2 (ㅏ), consonants 3 (a), vowels 4 (ㅣ) are entered in the form of words and no cursor movement is required. .

-If you enter 'galchi' : consonants 1 (a), vowels 2 (ㅏ), consonants 3 (ㄹ). Words are formed by consonants 4 (vo) and vowel 5 (ㅣ), and no cursor movement is required.

-'Read' input : consonants 1 (ㅇ), vowels 2 (ㅣ), consonants 3 (ㄹ), consonants 4 (a), consonants 5 (a), vowels 6 (ㅗ) is entered into a separate cursor No moving work is required.

-If you enter 'previous' : consonants 1 (ㅇ), vowels 2 (ㅏ), consonants 3 (a), consonants 4 (a), vowels 5 (ㅏ) is entered as 'musicians'. Therefore, enter 'ah', move the cursor, and enter 'ka'.

In the above, consonants 3-> the third input means consonants

Vowel 4-> the fourth entry, meaning vowel.

That is, consonant n means consonant as the nth input without consonant vowel classification.

In the case of a separate cursor movement operation as described above, the average of 5% or less is very low, so that characters can be continuously inputted as if a character is input from a computer keyboard. FIG. 1 illustrates an example of an arrangement of a basic sentence type for Korean input, and may be arranged by modifying an order of the arrangement or a shape of the basic sentence type, which is naturally included in the technical idea of the present invention.

When the basic character is input in the basic sentence form as described above, it is expected to bring about a large change in the character input method of the mobile phone which is widely used because the Korean characters can be easily input from the limited input unit.
