Field of invention

The present invention relates to the field of information input, and in particular to a keypad information input device and an input method using the same. Background technique

At present, the probability of entering language information using a keypad, especially a numeric keypad, is getting higher and higher. Especially in the current network era, computers are becoming more and more miniaturized. It is very necessary to enter language information on mobile phones. This is becoming more and more powerful, and this momentum can only increase. Generally speaking, language information is entered on twenty or more keys. However, since the trend of miniaturization is inevitable, the keypad is especially The digital keyboard will undoubtedly become one of the main keyboards for information input in the future. In particular, the digital keyboard is compatible with the text keyboard. In order to meet the trend of miniaturization, we must invent better products and methods of use. When inputting information, usually pressing a key on a key will produce a character, which will slow down the input speed. For example: When entering English select on a mobile phone, you must press 777733555332228 to reduce the efficiency, of course. This problem is encountered when inputting various texts in the world. not excluded.

Preferably, the method for inputting letters and Chinese characters by using a small keyboard further includes the step of: 'selecting desired Chinese characters by using numbers or stroke keys.

According to the present invention, an efficient numeric keyboard or keypad information device is characterized in that the number of keys of the keypad should be less than the number of standard keyboards, such as less than 101 standard keyboards, or less than 26 information input keys.

The keyboard includes radio buttons and key combinations. Among them, the radio button indicates that only a specific unique letter or character is input; the combination key refers to inputting other letters or characters through key combinations, and each combination key represents multiple letters or characters.

With today's telephone numeric keypad, one key can be repeated multiple times to enter one or more information. The combination key of the present invention is the continuous input of two independent keys to obtain a result of inputting one information or multiple information, which is a feature of the combination key.

A further design scheme is that the number of combination keys is two keys, that is, continuous input of any two combination keys or a combination and arrangement to input a letter or character, that is, the first combination key is selected to select the combination key Multiple letters, followed by a second keystroke to select the letter Bit order.

In addition, the information input key is less than or equal to ten key units.

The above keyboard can double as a numeric keyboard.

The above keyboards can be phones, mobile phones, computer keypads, etc.

In the keyboard described above, there are at least a part of text information input radio buttons and key combinations. Assume that the number of constituent keys or the number of keys is A, the number of squares is the number of key combinations, and the number of keys is defined as B, and the result of the combination is C.

When the composition number A of the combination key is 5, the square value B is 2, and the combination result value C is 5 * 5 = 25, at least 25 information input results can be obtained.

When the composition number of the combined key is 6, the squared value is 2, and the combined result value is 6 * 6 = 36. At least 36 information input results can be obtained.

For example: Each key combination represents 1-5 characters and letters. If there are 5 key combinations in total, if each key represents 1-5, the combination of two keys can get 25 results, so you can get 25 Enter selection.

If several key combinations are arranged in sequence, the sequence (keyboard number) is represented by X, and the character and letter sequence represented by each key is represented by Y. If we want to input any one of the letters it can represent through the key combination, Character information can be obtained by entering the corresponding X (key) + Y (key) respectively.

In the present invention, the keys or radio buttons for inputting unique letters or characters are arranged to input high-frequency letters as much as possible. ·

In the input of text information, there is always some high-frequency letters and some low-frequency letters in any kind of text. The high-frequency letters can be input more efficiently with one key, and the non-high-frequency letters can be input with key combinations.

Because the proportion of vowels of their words in various languages is relatively high, some or all of the keys (radio keys) to enter unique letters or character information are arranged to enter vowels or are defined as vowel alphabet Select key. By using the keyboard and the input method of the present invention, letters and Chinese characters can be efficiently input on a small keyboard.

2 is a distribution diagram of a keypad according to another embodiment of the present invention;

3 is a distribution diagram of a keypad according to another embodiment of the present invention;

4 is a distribution diagram of a keypad according to another embodiment of the present invention;

5 is a distribution diagram of a keypad according to another embodiment of the present invention;

6 is a distribution diagram of a keypad according to another embodiment of the present invention;

FIG. 7 is a distribution diagram of a keypad according to another embodiment of the present invention; see the keypads in FIGS. 1, 2, 5, and 6. Among them, the key 1 represents the number 1 and the letter hbcdf, expressed as (X:) 1 = (Y:) hbcdf; key 2: (X:) 2 = (Y:) ngjM; key 3: (X:) 3 = ( Y:) rmpqv; Key 4: (X:) 4 = (Y:) swxyz; Key 5: (X:) 5 = (Y:) When switching to letter input, the control system (not shown,-field) The skilled person is familiar with this technology) When receiving the signal of tapping the first key, it is determined that the user wants to input the letter group represented by the first key, such as typing key 1, which means that the user wants to input one of hbcdf; then, the control system receives When the signal of the second key is tapped, determine the bit order of the letter group, such as typing key 3, which represents the input (. For convenience, the abbreviation is 13 = c. All corresponding keystroke inputs are as follows:

1 l = h, 12 = b, l'3 = c, 14 = d ₃ 15 = f ₅

21 = n ₃ 22 = g ₃ 23 = j, 24 = k, 25 = l,

3 l = r, 32 = m, 33 = p, 34 = q, 35 = v,

41 = s, 42 = w, 43 = x, 44 = y, 45 = z

51 = t Among them, the vowel letters in English or Roman pinyin are A, E, I, 0, U, which have a higher probability of occurrence, corresponding to the numbers 6, 7, 8, 9, 0 of the keyboard respectively. Therefore, use the numeric keyboard or keypad to enter character or text information. The vowel key is a radio button as much as possible, and the consonant key is a combination key or a compound key.

Compound key: A compound key refers to the use of two or more keys to enter a character information or a text unit is defined as a compound key, which is similar to the combination key mentioned above.

Capitalization (conversion) key: In the present invention, an independent capitalization (conversion) key (Figure 5) can be set to convert the case of the letter.

Its usage is-

1. Uppercase switch. When the uppercase (convert) key is pressed, all letters entered thereafter are uppercase.

2. Lower case switch. When the lower case (conversion) key is pressed, all letters entered thereafter are lower case.

3. The switching can be performed alternately.

Number and character information input switching keys are used as switching function keys between number and character information input to determine the number input state or character information input state.

¾ A special key (see Figure 5) to switch between numbers and letters:

1. Number switch: When the switch key is pressed, the characters entered later are numbers.

2. Character switch: When the switch key is pressed, the characters entered later are character information.

3. The switching function of the switching key is performed alternately.

Other schemes different from this embodiment include: radio buttons for inputting non-vowel letter keys, such as consonant letter keys (T, N, S ...)

Also includes: Radio buttons include both vowel letter input keys and consonant letter input keys. Because vowels generally occupy a high frequency in text input, the highest may reach or approach 50% or more, such as national, come, etc. If we use a key to represent vowels, it will make a high proportion The letters are entered with one click.

Representing alphabetic keys or alphabetical letters: The keypad in the present invention, the corresponding input letter on the radio button, the character is the letter (key) of the key, multiple letters are arranged on the combination key, and the first letter (Y1) It is the representative letter (key) of the key. The first letter (Y1) of a key combination that enters letters in a key combination is a high-frequency letter.

After the control system receives the combination key, the control system does not hit another combination key and taps the radio button or the end key such as: space, etc. The control system enters the first letter of the combination key by default.

When a combination key is added with a radio button or an end key, the representative letter of the combination key, that is, the radio button letter or end character is obtained. For example: 6-key radio button, 1 + 6 key ha After entering the combination key, when you press the combination key once to change the non-combination key (such as 6 = a), it means to enter the first letter of the combination key. Such as h, r, t, s, n in English. When 1 key ^^ (3: £ ", enter l + 6 = ha

This advantage is: When you want to enter national, n, t, n three keys and one key are completed. In fact, nationa is completed with one key. This type of keyboard greatly improves the input speed.

In Figure 2, * and # can be used as the left and right shift keys respectively, and the # key can also be used as the space key and the end key.

Any letter key of the combination key plus space or end key or # key, that means to enter the representative letter of the combination key, for example: 1 key ^^ (^, 11 # means input h, can also mean Enter the end. 'For example: hat = 165 #, enter 165 # is equivalent to enter hat

The * key can also double as a delete key. When moving to the left, the crossed letters can be deleted. The combination of the two keys can be used as a symbol search key. Since there is a lot of character information that cannot be used when entering with the keypad or numeric keypad The key input requires special search, so a combination (double) key can be set as the search combination key. Search for numbers, punctuation, etc.

The present invention sets ten representative letter keys, among which the representative letters are the initial letter symbols on each numeric key, and five of them are combination keys representing the alphabet keys, and they are h, n, m, s, t, and Single keys represent alphabetic keys, they are a, e, i, u, 0 o

1 key = ¾1 ^ (^ (lhbcdf)

2 key = ngjkl (2ngjkl)

3 keys = rmpqv (3rmpqv) 4 keys two swxyz (4swxyz)

5 keys 2 t, uppercase, search, to be set, to be set (5t, uppercase, search, to be set, to be set)

6 key two a (6a)

7 key two e (7e)

8 keys = 1 (8i)

9 key -u (9u)

0 key two o (0o)

Combination key example:

11 = h; 12 = b; 13 = c; 14 = d; 15 = f; 21 = n _; 22 = g; 23 = j; 24 = k; 25 = 1; 31 = r; 32 = m; 33 = p; 34 = q; 35 = v 41 = s _; 42 = w _; 43 = y _; 44 = z; 51 = t 52 = capital control key combination. When you enter a letter followed by 52, the previous letter is changed to upper case. . For example: 652 = A, 752 = E, 852 = 1, 952: U, 052 = 0, 4252-W, 4352 two Y 1152 = Η; 1252 = B; 1352 = C; 1452 = D; 1552 = F; 2152 = N _; 2252-Η; 2352 = J; 2452 = Κ; 2552 = L; 3152 = R _; 3252/1; 3352 = P; 3452 = Q _; 3552 = V; 4152 = S; 4252 = W; 4352-Y ; 4452 = Z; 5152 = T

Of course, the 52 key combination can also be set in front, such as: 5251 = T

53 key combinations are search keys that can be used to search for characters

The 54-key combination and 55-key combination are pending keys, which can be used to expand functions.

When entering a combination key letter, the representative letter and initial letter corresponding to the key may be displayed first, and adjustment may be made according to the input situation of the second key.

For example: When we enter 1, the screen displays h first. If we continue to enter 2, the screen changes to b again, but it can change color before the second key is not entered or make some special symbol prompt under its character. The notice may be rewritten.

A keypad or numeric keyboard text information input method. When inputting a vowel letter in a pinyin word, use the corresponding number key to input it with one key, and when inputting a consonant letter, use the combination key corresponding to the consonant letter to input When the input letter is the representative letter or initial letter of the key combination, and the letter to be entered after it is a vowel, the representative letter or initial letter The representative letter can be entered by one key with its corresponding key.

An intelligent fast input method relying on the keyboard of the present invention:

Since the present invention can ensure that the vowel letter is input by one key, the vowel letter and its position can be fixed and retained when each word is input. When entering words, even if we do not use the combination of key combinations for consonant keys, the probability of error is limited, so we can use this feature to quickly input words, and basically guarantee the correct rate. No increase or even decrease, but the accuracy rate is still very high.

We can use the following methods to input. When inputting a word, each consonant or non-radio key letter (representative key) uses the key identified by the key to input one key, and the letter corresponding to the vowel key or radio button One-click completion (for example: a, e, i, o, u).

If there are more than one word corresponding to the input code, according to the principle of high frequency foresight, the words with high frequency are displayed first.

Selective smart input method

Because words with a small number of words are prone to re-coding in the intelligent input state, such as had and bad, we can specify that words with few letters can be set without intelligent methods to enter the limit of the intelligent magnitude of the input word. The limit number can be set according to the situation. The present invention provides an embodiment, if a word is 5 letters or more, it is input in a smart way.

For example: school can be entered in an intelligent way, and its corresponding code is 411002. The length of the input code is the same as the length of the word character.

When the letter to be entered is a letter in a combination key, no combination is performed, and only the corresponding key is entered, depending on the high-frequency selection method in the memory. The number key corresponding to each letter to be entered means that the letter is entered, and there is no need to correspond to the key combination.

That is, an intelligent and fast input method. Because sometimes a combination of keys must be used to input a letter with two keys, it will be lower than the input efficiency of one key and one word. Therefore, on the keyboard of the present invention, vowel letters can be one key. Input, non-vowel letters are also one-click input. The words corresponding to the code entered by it are displayed in a high-frequency and prescient manner For example, the input code of the is 517 corresponding to the word, the most frequent is the, but the possible combinations are t or h or b or c or d or f, the, tbe, tee, tde, tfe, of which only the may constitute a word , Other possibilities are very small, so just choose the first the. This input method is especially helpful for the input of words with many consonants connected, such as: school (swxyz) + (hbcdf) + (hbcdf) + 0 + 0 + (ngjkl) where school appears most frequently, so Show priority, school. Among them, the combination probability of sch is the highest, and the probability of the combination of the other three consonant letters in a single word is very low, such as: whh, xhh, yhh, zhh ... There is very little possibility of occurrence , Especially multi-character consonants appear consecutively, such as: 3 letters, 4 letters are of very few types. In this case, more intelligent input methods should be used.

In fact, the continuous consonant combination of words in each language in Pinyin text is very specific and rare, so if it is not a reasonable combination, it is easy to be excluded. Therefore, the intelligent and efficient input method is a very scientific and practical fast input method.

The keypads in Figures 3, 4, and 7. It is a highly efficient intelligent and non-efficient hybrid input. We can design the above-mentioned high-efficiency intelligence and non-high-efficiency intelligence compatible embodiment in the system, or we can select them by menu.

u = horizontal; 1 = vertical; 0 2 捺; E 2 prime; A = fold

If you input Chinese characters using the five stroke method through the keyboard, you can enter the keys corresponding to the five strokes separately.

As an embodiment, a, e, i, o, u respectively correspond to 6, 7, 8, 0, 9; for example, if you input "big" in Chinese characters, you can enter ueo, that is, 970.

When using the full spelling input method, depending on the keyboard solution of the present invention, vowel letters are entered by their corresponding representative letter keys, and consonant letters are entered by their corresponding key combinations, such as: "大" in daji = da input corresponding keys For 146

When using the stroke-pinyin mixed input method of the present invention:

We can set V as the initial consonant key, that is, when the pinyin of a Chinese character is silent, such as Euro = 011, at this time, the Chinese character has no initial, so V is used to represent its initial key. Method 1: If the first key is entered as a vowel letter, it is defined as a stroke input. If the first key is u (9), we are defined as the input stroke. If the first key is entered as a non-vowel letter, For example, b (12) is regarded as Chinese pinyin input and Chinese pinyin b is input.

In addition, the present invention can also perform the following input methods:

Single-word input method: Use the first letter of the initials plus the first letter of the finals and its corresponding number key, such as "汉" = HA, whose corresponding number key is 16.

Phrase input method:

Two-character words: the first consonant letter of the first word plus the first consonant letter of the second word and its first vowel letter and its corresponding number key, such as "Chinese" = HZI and its corresponding number The key is 11458.

Three-word words: the first consonant letter of the first word plus the first consonant of the second word, plus the third first consonant and its first final consonant and its corresponding number key. For example-"Communist Party" = GCDA and its corresponding number key is 2213146.

Four-character words: the first consonant letter of the first word plus the first consonant of the second word, plus the third first consonant and its first final consonant and its corresponding number key. For example: "Communism" = GCZYI and its corresponding number key is 221345448.

Example of mixed input of pinyin and stroke-Stroke complement code input method:

When inputting a Chinese character unit using the Pinyin input method, at least one stroke of one of the Chinese characters is used as the complement when the character unit is input, and is implemented by the keyboard of the present invention.

Use strokes as input for phrases and complements of words. When the first word (word) of a word or phrase input by the above Pinyin input method is not what you need, you can use the stroke of the phrase or the Chinese character Make two's complement input to find the exact phrase you need.

Maximum code length of complement code:

In order to prevent the input speed from affecting the input too much, the maximum code length of the complement can be specified. Quantity, when the complement number reaches this number, it will not be complemented.

Omit complements:

Complementary input does not need to input the maximum number of codes. If you find the word you need, you can stop complementing.

An important object of the present invention is to solve the difficulty of selecting Chinese characters. Since a general keypad is used for a display screen comparison device, the selection of Chinese characters cannot occupy too much area. The complement selection method can first display the first selected word. The selected word can also be changed during complement, so basically it can occupy as little area as possible.

For example: Input "Chinese character" first appears as "Chinese" with one's complement, then it becomes Chinese character, so that it can occupy less screen area.

Therefore, the Chinese character input and display method of the present invention is also an important invention point. When a Chinese character unit is input, (a Chinese character unit refers to a Chinese character or a phrase, and they are replaced by a set of input codes respectively). The addition of two's complement can be changed.

The above-mentioned embodiment is further described as follows. For example, "Han" = HA00UA0, the keyboard number of the present invention is 11600960.

—Character input: input with the first five strokes of the Chinese character

Two-character words can be entered using three strokes of the first word and two strokes of the second

In a further embodiment, the first three strokes of the first character plus the first two strokes of the second character may be determined as the complement code input. For example, the corresponding Chinese character input code is HZI00U00 and the keyboard input code of the present invention is 1145800900.

Three words are complemented with the first two strokes of each word, such as: "COMMUNITY" = GCDAUI0UI0

The corresponding keyboard input code of the present invention is 2213146980980

The four characters are complemented with one stroke of each character, such as: "Communism" = GCZYIU00E The keyboard input code corresponding to the present invention is 2213454489007

As already mentioned above, when inputting Chinese characters, you can 1. Perform stroke input of Chinese characters

2. Pinyin input for Chinese characters

3. Pinyin and stroke input of Chinese characters

Stroke input of Chinese characters relying on keyboard and input scheme of the present invention

1. Wubi input

Use the first five strokes of Chinese characters and the corresponding number keys to input, for example: "汉" = 00UAE, the number of the keyboard of the present invention corresponding to 00967

The phrase is entered using the first five strokes of each word and the corresponding number key, for example: "汉字" -00UAE00AAI

The corresponding keyboard number of the present invention is 0096700668

2.Six strokes input

Use at least the first three strokes of the first part of the Chinese character plus at least the first three strokes of the second part and the corresponding number keys, for example: "笔" = EU0EUU

Chinese character compatible input

The input of single-character characters of Chinese characters is compatible with the stroke input or pinyin input of Chinese characters (which may include the pinyin input, pinyin stroke complement code input, root input, etc.) described above.

Since the root input of Chinese characters is different from the last letter input of the Chinese character input method above, there is no vowel letter after the root input, so if you find the character we need, you can use the # key to confirm and select

The confirmation keys of the various character input units of the present invention can also be determined by the OK key.

— When entering the key code, the screen has shown exactly the character unit that you need, that is, you can confirm with "0K key".

Compatible auxiliary switching methods-purpose and effect. If the end key is frequently used during the input process, the time will be delayed. If it can be omitted, that is, the input of the end key is partially or completely omitted, the efficiency will be improved to a certain extent.

Since the present invention adopts the auxiliary element compatible input method, the end judgment can be made according to the auxiliary element input state.

Judging method:

When consonant input is performed, if a consonant appears again, it is the end of the previous input unit or the start of the next input unit.

Compatibility solution embodiment-one or more consonants (N consonants) plus one or more vowels (M (Vowel) is an input method, that is, a kind of input method.

N or M can be increased or decreased. When there are two types of awake, the number of consonant letters and the number of vowel letters represented by N or M are different.

Each bandit can be a word or a word input method. When N appears after a bandit, it means that the input of the word or word represented by the input method represented by the previous Li or the new Li The beginning of the input of the represented word or word of the input method represented.

Specific embodiments:

(a): N = l, M = l is a single character input for Chinese characters;

(b) _: N = l, M> = 1 for single-word input or single-word plus stroke complement input;

(c): N = 2, M = l is a two-character Chinese character input;

(d): N = 2, M> = 1 for Chinese character double word or double word plus stroke complement input;

(e): N = 3, M = l is a three-word input;

(f): N = 3, M> = 1 for three-character words or three-character words plus stroke complement input;

(g): N = 4, M = l is a four-word input;

(h): N = 4, M> = 1.

Super compatible input scheme:

Although the compatible input scheme was mentioned above, there are still some input methods that are not compatible. For example: Wubi drawing input scheme is not compatible. Because the previous scheme has two's complement input, the unnecessaryness of Wubi input is not displayed come out. Therefore, a spacer function key is needed to help achieve this.

Our implementation method is: set an end key, its role is to: end the input of a text unit of the input method mentioned above.

When we get the end information, we can enter other input methods to input Chinese characters or words accordingly.

The end key can be set individually, or it can be replaced by 0K key, right shift key or # key. Therefore, we can add several input methods to the super-compatible input scheme. N = 0, M> -1 is Wubi drawing input scheme;

N = l, M = 0 is a Chinese character or phrase input scheme;

N = 2, M = 0 is a Chinese character or phrase input scheme;

N-3, M = 0 is a Chinese character or phrase input scheme;

N two 4, M = 0 is a Chinese character or phrase input scheme;

N / 2 5, M = 0 is a Chinese character or phrase input scheme;

N = 6, M = 0 is a Chinese character or phrase input scheme;

In the super-compatible solution, that is, if the bandit (M = 0) or bandit (N = 0) and Li (M ≠ 0, N ≠ 0) are compatible, there should be an end key or a maximum code length limitation (when the code When it reaches a certain number, the input unit ends automatically).

Maximum code length limitation function:

The maximum code length limitation function is actually to reduce the use of the end key in order to improve the input efficiency. The usage method is: by specifying a maximum code length, when the code length is reached, the input unit naturally ends.

"This way you can end the input unit without the end key.

The search key in the drawing is a function key for symbol search. This key is used as the key for the search function. Press this key to start the search. Press the 0K key or the end key or other confirmation keys to end the search.

A number key plus this search function key starts the search. Press the 0K key or the end key or other confirmation keys to end the search. Each number key can search for a different alphabetic character.

Because when one-click search, if you need to search a lot of content, it will be very slow; if you place various possible search symbols on different number keys, the search time will be much faster.

Since the Chinese character input method of the present invention borrows the unique keyboard of the invention, it can freely input Chinese characters in a variety of methods on the keypad, greatly improving the degree of freedom of input, and creating very good conditions for inputting Chinese characters. The positive significance of the present invention.

The Chinese character input scheme of the present invention can be implemented on an English standard keyboard. Although the present invention has been described through embodiments, those skilled in the art can make various improvements and modifications without departing from the spirit and scope of the present invention, and therefore, the appended claims should include all such improvements and modifications.
