Description

Smart Input System for Characters And Numbers In A On-screen or Digital Keypad}

The present invention relates to the character input system of all electronic terminals (mobile phones, PDAs, electronic notebooks, navigation, etc.) and includes the character input technology fields of all electronic terminals, including the input technology field found in general mobile phones.

Background art can be divided into three categories. 1) QWERTY keyboard method with PC-keyboard environment; 2) mobile phone type using 3x4 keypad in telephone; And 3) there are significant differences between the two methods in the total number and arrangement of keys.

1) It is applied to mobile phones or small devices because it is the keyboard that is most familiar to PC users worldwide, but at least 30 keys are required. Therefore, small devices have various problems when applied to analog or digital keypads. First, the size of a single key is difficult to press, thus increasing the rate of typos. Second, even if the key layout is already memorized in the head, both hands are placed on the keyboard, but since the speed and skill of the PC keyboard can be reproduced, it is difficult to use both hands in small portable electronic devices. 8 There is no room for a finger, so the advantage of the familiar key layout is not effective. Third, even when using one hand / finger, the moving distance between keys is long and the moving method is complicated, which makes the user more uncomfortable.

2) If your PC has a QWERTY keyboard, small electronics such as mobile phones have a 3x4 (12) key input method using the numeric keypad. In English, it is divided into 2, 9, ABC, DEF, GHI, JKL, MNO, PQRS, TUV, WXYZ and it is inconvenient but unified. In Korea, QZ, ABC, DEF, GHI, While JKL, MNO, PRS, TUV, and WXY are unified, there are various input methods for each Korean manufacturer, which causes inconvenience to adapt to new input method when purchasing devices of other manufacturers. Representative commercial Hangul input methods include Samsung Electronics' Cheonjiin input method, Pantech's SK2 input method, LG's EZ input method, Motorola input method, and dozens of other patents. The most common of these is that the vowel zone and the consonant zone can be clearly separated on the keypad so that one straight line (or one broken line) can be divided. [Fig. 5] Otherwise, the input method of the same key mixed with the letter (eg, Lee Wan-soo's unified keyboard, or the best Korean dial (see Fig. 5), Seo Jung-hyun's input method, Hur Tae-ho's input method, etc.) Although ambiguity is not resolved, it causes confusion and inconvenience for the user. Common inconveniences of commercialized input methods include ambiguity in combining double vowels, double consonants, lattice sounds (Samsung's SK2 input method, such as double consonants (ㄲ, ㅃ, ㅉ, ㄸ). , ㅆ etc.), the same key must be entered three times in succession, ㄽ / ㅀ ambiguity resulting from the same key arrangement of 과 and ,, ㄼ / ㄿ ambiguity resulting from the same key arrangement of ㅂ and ㅍ Etc.-> To solve this problem, we added the time difference input method to recognize the characters that have been input so far after a certain time and move on to the next.) There are many problems, such as LG's EZ input method. In addition, the English input method is similar to the general input method used in the English-speaking language, so inconveniences in using it continue to exist.

3) There have been various attempts to break out of the above two methods, by extending the existing numeric keypad horizontally to add more keys (such as one-handed keyboard or CrossDial), or by tying the existing QWERTY keypad two horizontally by two characters to keep 14 keyboards (three stages). Typical methods include placing up to five keys per line, geometrical keypad shapes (eg, circular, honeycomb), and placing all keys even when the number of keys increases. There is also a moa key method (see Fig. 6) that displays only consonants by using the features of the touch screen. The vowel input window is displayed in anticipation of the vowel input after the consonant is input. The disadvantages are that it is inconvenient to get used to, and it may be problematic to be used in common with a dialing interface (3x4 array), and it is difficult to manipulate and store a complex vowel, such as a double vowel.

The following methods are frequently used to generate consonants. Among the consonants, ㅋ, ,, ㅌ, ,, ㅎ are considered to be lattice sounds of ,, ,, ,, ㅂ, ㅇ, and they are combined by inputting the key twice or adding a stroke addition key. , ㅉ, ㄸ, ㅃ, and ㅆ are regarded as a consonants or twin consonants of ,, ,, ,, ㅂ, 각각, respectively, and are combined by inputting the corresponding key twice or three times or by adding the consonant keys. LG's EZ input method and Motorola input method use the addition key or the double consonant key. The last possible consonants ㄳ, ㄵ, ㄶ, ㄺ, ㄻ, ㄼ, ㄽ, ㄾ, ㄿ, ㅀ, 가능한 are generated by combining several corresponding keystrokes (once or twice).

There are two main ways to generate all vowels or neutrals: the combination of just three keys, the old KTF EVER input method [see Fig. 5], or the Motorola input method [see Fig. 5]. There are five ways to use representative keys such as,,,,,, and. The former method has the advantage of having a shorter moving distance instead of having a higher number of inputs than the latter, but has a disadvantage in that a more skilled period is required in that the input sequence may be confusing in complex vowels such as ㅞ and ㅖ. The latter method has the advantage that the combination is more rational and simpler than the former, but may have a disadvantage in that the moving distance is large.

The problem to be solved by the present invention is as follows.

1. Minimize the number of keystrokes: To minimize the number of keystrokes, it is good to get a lot of letters with one down. In the case of Hangul, less than the number of combinations on the QWERTY keyboard is a success. In the case of English, it can be said that it is efficient if it can obtain the most frequently used plural consonants or double vowels such as spr, str, pr, tr, wh, ea, ai, ou.

2. Minimization of travel distance: Ideally, it can be done within a similar radius in the generation of multiple consonants, multiple vowels. In the case of Hangul, there should be no difficulty in proceeding with the initial-neutral-thickness-first or the initial-neutral-first-neutral equation.

3. Minimization of typos: In the conventional input method of 3x4 pad method, the combination method through the same key repeated input is inevitable due to the limitation of physical space, but the advantage of using the same key is easy to remember. The disadvantage of increasing the probability of typos caused by errors remains a homework. Devices that depend on minute pressure transfer or static electricity from a finger, such as a touchpad, highlight this shortcoming. Example: Multiple input methods (heavenly, Motorola, SKY, etc.) place double consonants or lattice notes on the same key.

4. Resolving Ambiguity: This phenomenon occurs not only in Korean but also in English input. It refers to the ambiguity caused by the complex rules of the same key duplication and combination mentioned above. In the case of Hangul, if the finality of one letter and the first letter of the next form a legitimate finality, the system cannot determine whether the former or the latter is correct. In this case, in the case of the existing input method, it is difficult to solve by forcibly converting to the next character input standby state through a specific key such as a space. For example, a judgment may be ambiguous immediately after inputting "day" in "read" and immediately after entering "a" and immediately after entering "day" in "work" and "a".

5. Correlation between Hangul and English maps: Even Korean users may mix English and Korean, such as sending e-mail address, terminology, and international text, or often use English. Can be minimized.

The present invention has the following characteristics with respect to input of all languages (typical examples: Korean, English, Spanish, English-speaking languages) with distinct consonants and vowels. [See Fig. 1]

In the character input system of all electronic terminals (mobile phone, PDA, electronic notebook, navigation, etc.),

1) The terminal input device is basically composed of a physical keypad 100 that detects text input, a screen keypad P110, and a text input display unit P120. In the case of a terminal having a touch screen, the physical keypad and screen The keypad is the same. The screen keypad is basically composed of two small keypads (A, B). The configuration of keypad A (P111) is based on consonant input and the configuration of keypad B (P112) is centered on vowel input. Simultaneously display on the screen to allow two-handed input or to switch between keypads and display one of them first to enable one-handed input,

2) In the method of inputting characters

i) waiting for an input signal and determining whether a connection signal is transmitted to the surface of the physical keypad P100 (Touch Down);

ii) recognizing whether the position of the access signal corresponds to a cell section which is the minimum input unit constituting the physical keypad;

iii) any other valid combination (e.g. double vowel, double consonant, double consonant, lattice, etc.) within the same keypad that can be constructed in connection with the character corresponding to the entered cell area; Reconstructing (P110) to display valid combination characters in the surrounding cells;

iii) determining whether the access signal is touched away from the physical keypad or is leaving the current entry zone while the access signal is maintained;

iv-1) exposing a character (consonant or vowel) displayed in a corresponding cell area to the character input display unit P120 when the access signal is separated from the physical keypad;

iv-2) If the access signal is maintained and has left the current entry space

A) if the access signal is maintained while entering another cell, go back to step iii);

B) when the access signal falls away from the physical keypad with leaving the current entry compartment, if there is a legal combination compartment in the direction of departure from the current entry compartment or if the last recognized compartment is a legal combination compartment Exposing the text input display unit;

v) If the display method is a one-handed input method, and one keypad is displayed on the screen at a time, when the access signal is finally separated from the physical keypad and the characters are exposed on the character input display panel, another type of screen keypad (A to B, B to B) is displayed. It is characterized by using a separate switching method (specific key or specific method) when exposing A) to the screen and wanting to return to the previous type of keypad.

Fields that can see the effect through the application of the technology of the present invention are as follows.

1. Input speed improvement in small electronic devices

2. Improved input convenience in small electronic devices

3. Pursuing input uniformity and expandability in small electronic devices

1. The input speed of the small electronic device through the present invention seeks to be superior to and faster than existing existing similar input methods even though the input speed through the keyboard in a general PC environment is not high. The evaluation of the input speed can be made by comparing the number of repeated inputs, moving distances, and comprehensive comparisons of words and phrases that are frequently used scientifically. In Korean, Samsung Cheonji, LG EZ, Pantech's SKY2, CrossDial, Moaki The comparison is made with five representative input methods, and in English, it is compared with three representative input methods such as QWERTY input method, English-speaking input method, and Korean English input method.

2. The input convenience to be pursued in the present invention is based on providing a convenient structure for both two-handed, one-handed, one-finger, and the like, and resolves ambiguity, readability of key arrangement, memory convenience, and movement. It takes into account the distance, the total number of keys, and the like. As above, the comparison is made with various existing input methods.

3. The unity to be pursued in the present invention refers to the similarity with the existing 3x4 structure, the similarity between the Korean and English input methods, and the unification of the input method rules (with few exceptions) that are easy for the user to understand. Means considering the foundations that may be applied to other languages or applications other than Korean and English.

Through the present invention, the above-mentioned problems can be solved as follows.

1. Minimization of the number of key inputs: It is a feature of the present invention that the screen keypad can be implemented to input all the double or triple characters (consonants or vowels) on the keypad with one key input. It can be solved within two or three strokes per syllable compared to having to input as many as the number of inputs. For example, the letter '꽥' is required for up to six strokes in the existing input method, but in the present invention, it is input within three strokes. In the case of English, one syllable called spring takes 6 strokes in the existing input method but is input in 3 strokes in the present invention.

2. Minimize the travel distance: It is possible to minimize the travel distance by placing the consonants frequently combined in the generation of multiple consonants and multiple vowels as close as possible.

3. Minimization of typos: In the existing input method, different letters are placed on the same key so that the input result varies depending on the click (1 stroke) and the double click (strike). Is generated. In the present invention, two key pads can overcome the physical limitations of a single keypad and can be designed to allow a letter combination without a method of placing multiple letters on the same key, thereby reducing the error rate. In the existing input method, 12 (3x4) basic cells exist, but in the present invention, 24 cells can be utilized, and 11 additional cells can be used for each cell by reconfiguring the screen keypad so that up to 264 (11x24) virtual cells can be used. Can be used.

4. Resolution of ambiguity: In the existing input method, it is possible to solve the ambiguity caused by the combination only through time difference input or specific key input, but in the present invention, it is possible to move to the next type of keypad by simply disconnecting from the physical keypad. 'B' and 'ㄹ' are placed on the same key in Cheonjiin, SKY, and (formerly) KTF EVER, so 'B' and 'ㄹ' are displayed once, such as "Human", "Onnuri", "Cola", "Indoor" Ambiguity exists when they are mixed or the same word is repeated in succession. This ambiguity also leads to typos. In the same way, 'ㅇ' and 'ㅁ' are assigned to the same key in Cheonjiin, and 'ㅇ' and 'ㅎ' are arranged in the same key. Ambiguity exists when the words are repeated in succession. In the present invention, since the same key arrangement can be avoided, this problem can be solved simply.

5. Association between Korean and English maps: In the conventional input method, there is no relationship between Korean maps and English maps, so users have difficulty when entering English. You can also easily enter English.

The method of inputting the character of the present invention has been described in detail in the above [Problem Solving Means], and here some examples will help to understand the invention. The display of the input is represented by the symbols of the numeric keypad like 0 ~ 9, *, #. The symbol in parentheses () is a representative symbol of the cell where disconnection is made. The number of <> is the number of key inputs of the present invention, and the number of [] is the number of key inputs of Cheonjiin.

1. Hangul input method: (Apply the representative Hangul keypad of Fig. 3 among various possible combinations.) (In case of consonants, when it is necessary to distinguish whether it is a final word, the method is released in (5). If you live, greet you
