Description

Technical Field [0001] The present invention relates to a touch-screen input terminal,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyboard and an input method for inputting English alphabets of a portable terminal, and more particularly, to a keyboard and a keyboard for inputting English alphabets of a portable terminal, and more particularly to a keyboard, a tablet PC, a smart phone, a PDA, The present invention relates to an English keyboard and its input method for a portable terminal that can easily and quickly input English alphabets in various portable terminals using the portable terminal. Such a small keypad is widely used not only for a conventional short message (SMS) input but also for various kinds of data processing using a memo, a tweeter, a portable information device, and the like. It is a situation.

The present invention relates to a method of inputting characters in a portable terminal, and more particularly, to a method of inputting a character by displaying a virtual keypad on a display unit in a portable terminal having a touch screen, The present invention relates to a keyboard for inputting characters in a portable terminal having a touch screen for inputting characters in a case where a plurality of characters are allocated, and an input method thereof.

The English alphabet has 26 characters, but it is limited in size. In the case of a smartphone having 12 (3x4) key configuration, it is difficult to input it.

The input method of the English alphabet can be roughly classified into a method of arranging three or four characters redundantly in one key (a multi-tap method) and a QWERTY keyboard of a computer keyboard. Among them, the multi-tap method has a disadvantage in that the number of times of pressing is increased in the case of the characters arranged in order because the plural characters are arranged in one key redundantly.

Especially, the multi-tap method is arranged in a simple lexicographic order irrespective of the frequency of use, and there is a problem in that a button must be pressed several times in order to input a frequently used character. In addition, if you need to input characters repeatedly arranged in the same character or one key, you have to move the cursor to the next character after the cursor blinks 3 times regardless of the skill of the user, If the timing is not correct, an error may occur in which other characters of the same string are input.

On the other hand, in the case of the QWERTY system, since 26 keys are arranged on a narrow keyboard, the size of one key is too small, and the interval between the keys is narrow. Also, in a smartphone with a small size, when using a QWERTY keyboard, you can not use all the fingers as you would with a computer. Even if you hit it with both hands, you can only use two fingers. The difficulty of inputting these characters ultimately hinders the miniaturization of the device.

For reference, Korean Patent Registration No. 11682113 by the present applicant is a method of inputting Korean (English) numbers and becomes a mother of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a keyboard and an input method for English input using a touch screen of a terminal of the present invention will be described in detail with reference to the accompanying drawings.

According to an aspect of the present invention, an English input keyboard using a touch screen of a portable terminal will be described. The terminal is intended for mobile phones having a relatively small input and display area, but it is not limited to such and includes various portable terminals using a touch screen such as a keyboard for a computer input, a tablet PC, a PDA, navigation, MP3, IPTV and a kiosk can do. It is equipped with a microprocessor, memory, and input / output interface for input / output to / from the touch screen on any device. Accordingly, the keyboard of the present invention is displayed on the touch screen according to a predetermined algorithm in the memory, and input is also performed through the touch screen.

Hereinafter, referring to the accompanying drawings, a keyboard for English input using a touch screen of a terminal according to the present invention has a structure composed of 13 keys in total using mappings including yin and yang five lines.

Specifically, the keyboard structure of the present invention has three rows and three rows as shown in the figure, and the internal key 14 (four keys) in four directions around the center key 12 of the second row and the second row ) Are combined to form a total of five (5) five-keyed keys and eight (8) external keys 16 to form the Yin-Yang chain.

The overall configuration of the keyboard is such that four internal keys 14 are disposed on the outside of the center key 12, which is one of the five keys, and 13 foreign keys 16 are disposed on the outside of the internal key. Key.

According to the detailed configuration of the present invention, the letters constituting the English words are sorted according to the five-syllable five-line key according to the five-syllable five-letter key, and then the letters are arranged in the keys according to their characteristics as much as possible.

In general, consonants belong to Yin and Yang, and these Yin and Yang are expanded into two phases through two changes. Thus, the 21 sounds representing the consonants are arranged in the center key 12 among the eight keys and the five keys.

In English, there are five vowels in total, and these vowels are uniformly arranged in the second column including the central key.

According to the detailed configuration of the present invention, when the consonants are arranged in the center key 12 and the eight foreign keys 16, three concentric arrangements are arranged in the first and third columns, This is because the combination with the auxiliary key is considered. This is because when you use a smartphone, you usually use two thumbs to enter, so you have to place a large number of consonants in the first and third rows near the thumbs of both hands.

According to the detailed configuration of the present invention, consonants repeatedly arranged on the same key are arranged in order according to the frequency of use. This is to reduce the number of input strokes by first sorting the most used characters. The second most frequently used character is arranged second, and the third most frequently used character is inputted easily.

In addition, in consideration of the correlation between characters in the use of characters, both hands can be alternately used for inputting, or the fingering distance can be minimized. For example, when consonants such as t and h, s and t, n and g are consecutively input, the fatigue of the finger is increased when the input is continuously performed by one hand.

According to Samuel Morse who invented the Morse code, E is the most used in the English alphabet, followed by T, A, I, N, O, S, H, R, D, L, U, Followed by C followed. Most of these frequently used alphabets are arranged first in each key, so that the main alphabet can be input with a single touch. Followed by the second and third digits in the order of decreasing frequency.

Particularly, the vowels E, A, and I having the greatest frequency of use can be easily and quickly input by disposing the vowels E, A, and I in the central key and the internal key of the second row, which can be accessed most quickly. The consonant T is arranged in the second column of the first column because the words starting with T are the most common and the most frequently used consonants. The semi-consonant W also includes the vowel character, so that it is arranged along with the vowel in the center key 12.

By placing the consonants mainly in the external keys 16 and arranging the vowels mainly in the second row, when the input is performed with the thumb of both hands, in most cases, in most cases, the thumb is not moved horizontally but diagonally (diagonally) It is much easier to enter the body structurally because it moves in the form of. And there is an advantage that the finger can easily memorize from simple finger movement through repetitive input.

By using this keyboard repeatedly by the users, it helps to learn English more easily because it can understand the meaning of the invisible hieroglyphs of English alphabets and at the same time have a relationship between each alphabet .

According to the detailed configuration of the present invention, two keys 1, 2, and 3 are distributed and arranged in six keys including 0, the internal key 14 and the second row first and third columns in the center key 12 And numbers from 4 to 9 are arranged in the remaining keys. Place 0 in the middle key (12) in the middle of the five-way key, because 0 means the middle of the five-way street, which serves as a channel for communication with the third party (1,2,3). The number 1 to 3 is arranged in the internal key 14 on the right key and in the first row and the third row of the second row because the three characters represented by the numbers 1, 2, and 3 are deeply involved in the communication process. Numbers from 4 to 9 can be arranged in various forms to match the changes in the communication process of the four elephants in the remaining keys.

According to another aspect of the present invention, there is provided a method of inputting English into a touch screen of a terminal using the keyboard, The first arranged letter (alphabet) in a singly arranged letter (alphabet) or a duplicate arranged key is pressed once by the corresponding key, and the second arranged letter in a duplicate arranged key is pressed once The second set of auxiliary keys on the rear inner key 14 is pressed once and the third arranged character is pressed on the corresponding one of the two auxiliary keys on the inner key 14 And the input is continuously pressed.

By doing so, all characters can be input by touching the key within three times. In particular, in case of a character having a high frequency of use, the input can be performed quickly because the input is performed by one touch.

In particular, in order to input the second and third arranged letters (alphabets) of the redundantly arranged keys, a combination of the corresponding key and the auxiliary key on the internal key 14 is used to input the same character If you need to input repeatedly arranged characters in one key, you can eliminate the disadvantage that the cursor has to blink 3 times and move the cursor to the next character regardless of the skill of the user.

The two keys on these internal keys (14) are designated as auxiliary keys for input, the characters arranged on the left are input in combination with the right auxiliary key on the internal key and the characters arranged on the right are combined with the left auxiliary key on the internal key This not only allows you to use both hands equally, but also allows quick input.

According to the detailed configuration of the present invention, a user can directly register a word or an idiom with the combination of one of the auxiliary keys for two inputs on the internal key 14 and any one of the keys on the external key 16, These registered words or boilerplate can be directly called and input by the user when input is needed later. This allows long words or phrases to be entered with just four touches.

For example, if you register the frequently used greeting "Good morning." In advance as a boilerplate, you can enter it in only four. In particular, by providing two channels of words and boilerplate, users can easily and quickly input not only words and phrases that are frequently used, but also long phrases.

In the input method using the words or the above-mentioned basic phrases, not only the words and the phrases registered directly by the user of the mobile phone terminal, A method in which at least one of a set word or a boilerplate, a word frequently used by a user, or a boilerplate is mounted in advance in a memory and is loaded in accordance with an algorithm determined in a main input part of the keyboard, .

It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
