Technical field

The utility model relates to a kind of input information device, more particularly, relates to a kind of miniature keyboard that can greatly reduce number of keys and keyboard size.

Background technology

The data input is the necessary functions of various electronic equipments, and in present most input method, the keyboard input is still maintaining the leading position aspect speed and the degree of accuracy. Along with the continuous miniaturization of electronic equipment, input equipment is also constantly dwindling size.

In the prior art, the miniaturization of keyboard exists certain restriction. At first, can input with finger easily in order to make the user, the size of button can not be too little, and button is too little then not to be with the finger operation, to be exactly to produce easily maloperation. Secondly, in order to input enough numerals and character, will guarantee that key has the button of abundant quantity. It is the progress of miniaturization that two aspects are restricting keyboard.

QWERTY keyboard once can only hit makes a call to a key, if a syllable can be finished typing with two keys, with 120 words/minute the syllable of speed typing Chinese, need to hit key 240 times in every minute, need to hit key each second 4 times, it is readily accessible that this has not been that the ordinary people holds; And finger is very easily tired, can not work long hours.

There is a kind of quick-recording machine on the existing market, can realizes that the keyboard size of miniaturization and fast recording combine. As shown in Figure 9, show the design of the special-purpose keyboard of quick-recording machine.

The special-purpose keyboard of quick-recording machine, as shown in the figure, minute left and right two parts, each 12 key mapping, the arrangement of its key mapping code, both sides are the same, all adopt the Latin alphabet block letter of capitalization. The key mapping code on the left side is for left hand, the right for the right hand, the key mapping code of left and right two hand control respectively comprises 4 acoustic codes (B, D, Z, G), 6 rhyme codes (I, U, N, E, A, O) and two function codes (X, W). " X " be the double combination code of making acoustic code also.

The pronunciation of key mapping code is as follows:

The key mapping code	X	B	D	Z	G	W	I	U	N	E	A	O
													The phonetic phonetic notation	xi	bu	de	zhi	ge	wa	yi	wu	en	e	a	o
The Chinese character phonetic notation	System	No	{。##.##1},	It	Individual	Dig	With	Nothing	Grace	Volume	{。##.##1},	{。##.##1},

The key mapping code is arranged in a certain order, and " X ", " B " are arranged in the foremost, and arranges according to the principle of " from top to bottom, from the centre to both sides ". It sequentially is followed successively by:

X B D Z G W I U N E A O

Putting in order of key mapping code immobilizes, and always writes from left to right in order. But, reading custom in order to look after to recognize, every " N ", " A " occur simultaneously, or writing " AN ". The key mapping code of left and right two hand control respectively comprises consonant coding (acoustic code), simple or compound vowel of a Chinese syllable coding (rhyme code) and function code (X, W).

The design principle of quick-recording machine coding is described below. Take the design principle of its acoustic code as example.

1. encoding scheme

Establishment acoustic code used key mapping code itself is exactly only have 4 of acoustic code, i.e. " B (bu) ", " D (de) ", " Z (zhi) ", " G (ge) ", and remaining all will lean on these key mapping codes mutually to make up to consist of.

The coding of whole 21 acoustic codes is as follows:

Coding	Pronunciation		Coding	Pronunciation		Coding	Pronunciation		Coding	Pronunciation
												B	(bu)	No	BG	(pu)	Spread	XB	(mu)	Wood	XBU	(fu)	Secondary
D	(de)	{。##.##1},	BD	(te)	Special	XBD	(ne)	{。##.##1},	XD	(le)	{。##.##1},
												Z	(zhi)	It	BZ	(chi)	Eat	XZ	(shi)	Be	XBZ	(ri)	Day
DZ	(zi)	Son	BDZ	(ci)	This	XDZ	(si)	Extremely
												G	(ge)	Individual	XBG	(ke)	Can	XG	(he)	With
GI	(ji)	And	XGI	(qi)	Its	XI	(xi)	System

Code has 21 acoustic codes, and all acoustic codes have fixing pronunciation, and corresponding with a fixing syllable code, this is the syllable code of acoustic code representative, can beat acoustic code and input by hitting separately. This point and the Chinese phonetic alphabet are different, the initial consonant of the Chinese phonetic alphabet, although fixing pronunciation is also arranged, that is for the convenience that exchanges, and makes mute or the very faint initial consonant of pronunciation can read aloud, and can not be separately the Chinese character phonetic notation.

2. key mapping code and fingering

The key mapping code that acoustic code is used mainly is " X ", " B ", " D ", " Z ", " G ", and individual other acoustic code has been used " I " and " U ", and these all are the key mapping codes that is arranged in the front. The key mapping code that consists of acoustic code mainly leans on thumb and forefinger to hit and beats, have indivedual acoustic codes to use middle finger.

For its rhyme code, the key mapping code of using is " I ", " U ", " N ", " E ", " A ", " O ", with respect to acoustic code, after the sequence of these key mapping codes is leaned on, meet Chinese Pin Yin pseudonym front, simple or compound vowel of a Chinese syllable after join standard together. The key mapping code that consists of rhyme code hits by middle finger, the third finger, little finger of toe to be beaten, so that the middle finger frequency of utilization is the highest more flexibly.

The many key click principle of quick-recording machine

All key mapping codes that consist of each yard require and can enough one hands once hit the key action all and hit and press out, rather than be to hit successively to beat each key as QWERTY keyboard, this is exactly quick-recording machine " many key click " principle, also is the basis of the unusual characteristics of its fingering and high-speed striking.

But can see, be fast typing, this quick-recording machine keyboard need to be transferred whole fingers in the flexibility that reduces operation, has also limited the further miniaturization of keyboard size. And, by analyzing above-mentioned quick-recording machine keyboard as can be known, although it can be than the efficient fast input character of conventional keyboard, adopt the key mode of hitting of many key click, hit by hands the typing that once can finish two syllable codes, but because its key arrangement is dull, exist the defective that maloperation and the not easy and quick input of operation need long-time training.

Wherein two of first key arm 1a and two arm 2a of 1b and triple bond and the distance that 2b is relative and the interval is certain, wherein this distance can be as far as possible little, only otherwise mutually interfere and get final product, the second and the 4th key be in first and triple bond around among, and the distance with three interior sides of the 1st, 3 keys can be as far as possible little respectively, only otherwise mutually interfere and get final product.

The benefit of the keyboard structure that so arranges is that its volume can be very little, for example can accomplish 2cm * 2cm. When being held in the hand, for example only just can operating extremely easily these four keys with thumb, and can reduce the generation of mistake probability.

We know that according to arranging the combination rule, four keys have 2⁴Individual permutation and combination method, namely 1,2,3,4,12,13,14,23,24,34,123,124,134,234,1234,0 (sky, namely button does not produce any output). Wherein independent the first input key 1 of 1 expression is analogized with this; First and second input key of 12 expressions makes up, analogizes with this; 123 represent first, second and third keys combination, analogize and first, second, third and fourth keys combination of 1234 expressions and the strong operation of 0 expression nothing with this.

The utility model adopts these how much level multiple increasing laws arranging combination just, proposes the keyboard structure of this kind novelty,, adopts the mode of pressing simultaneously the combination key that is, comes input message.

The below is explained as an example of digital 0-9 example, asks for an interview table 1.

1	2	3	4
				1	2	3	4
5	6	7	8
				12	23	34	41
Control symbol 1	9	0	Control symbol 2
				234	123	341	124
*	#
				13	24	1234	Empty

In table 1, digital 0-9 to be entered illustrates with shade, and corresponding key mapping code is shown in next-door neighbour's the next line. From table, can see, press respectively first, second, third and fourth key and can export respectively numeral 1,2,3,4; Press simultaneously first and second the combination key can input the numeral 5, simultaneously press second and third the combination key can input the numeral 6, simultaneously press third and fourth the combination key can input the numeral 7, simultaneously press the 4th, one the combination key can input the numeral 8; Press simultaneously first, second and third the combination key can input the numeral 9, simultaneously press third and fourth, one the combination key can input the numeral 0. Therefore, the utility model only just can be inputted at least 10 characters by four buttons. Compare with the prior art keyboard, can save at least the space of 10 buttons.

Special keyboard particularly suitable of the present utility model is in to input numeral as main occasion, such as mobile phone, cashier's machine etc.

Take mobile phone as example. From table, can see, the code bit that is made of above-mentioned four keyboards still has five not use, therefore, be used in above-mentioned other code bit under the situation of input respective digital, can represent machine open/close key and connection/dialing button, represent " * ", 24 expression " # " with 13 code bits also still have code bit " 1234 " for subsequent use with code bit 234 and 124.

This shows, can be applied to fully mobile phone, cashier's machine etc. according to the keyboard that the utility model proposes and mode of operation thereof.

The machinery of each button of the present utility model, electric or software realize for those skilled in the art it then being apparent. As the button that can adopt existing commonly used keyboard or as the button of mobile phone and other such as arbitrarily form and the circuit and realize in conjunction with corresponding input method software of being correlated with such as soft-touch control or touch-screen.

The below describes with the 4-16 decoder and can be used for an examples of circuits of the present utility model, as shown in Figure 2. Four output state lines of corresponding described four buttons are connected respectively to a decoder commonly used 20, are used for identifying described key down state. For example when pressing second and third key simultaneously, No. 6 line of decoder 20 gatings (i.e. No. 6 line output high level). When the controller in the mobile phone detects No. 6 line and is high level, then show numeral " 6 " at display. As a same reason, when for example press simultaneously second and third, during four keys, then No. 14 line selection is logical. Telephone number with user's input when controller detects No. 14 line output high level sends.

Selectively, also can detect by software programming or prior art keyboard scanning circuit commonly used the signal output state of described corresponding four keys, its principle and above-mentioned decoder are similar. For example, when the signal output that detects corresponding second and third key becomes high level, think that then second and third key is pressed simultaneously, therefore, output numeral " 6 ".

In addition, the applicant it is pointed out that the code bit layout of corresponding four keys of the utility model can be arbitrarily, and the arranged mode in the above-mentioned table 1 just is convenient to memory, and is non-limiting and necessary. Obviously, for example the code bit of the second row and the code bit of fourth line can be exchanged, can export respectively numeral 5,6,7,8 thereby press respectively first, second, third and fourth key; Press simultaneously first and second combination key exportable digital 1, the time press second and third combination key exportable digital 2, simultaneously press third and fourth combination key exportable digital 3, press the 4th, one combination key exportable digital 4 simultaneously.

In addition, the utility model mention as the relevant circuit such as decoder both can with as described in keyboard be produced on, namely be encapsulated in the pedestal, but very obvious, also decoder etc. can be divided with described keyboard and be arranged, as be placed in the upper machine such as computer or other any treatment facility that links to each other with keyboard, and keyboard only need provide the signal line of corresponding key-press status. The keyboard volume that obtains thus will more can be small and exquisite, frivolous.

But selection of land, the 6th key 6 in the present embodiment can not occur with the button form, but one for example be installed in the pedestal or put on obliquity sensor on the finger, when needs input capitalization or part numeral, pedestal or finger can be rotated a predetermined angle, realize being equivalent to the triggering of the 6th key 6.

[embodiment 6]

In the present embodiment, the utility model proposes a kind of can be according to the input keyboard of spell Chinese character input, this input keyboard is by two groups of input cell formations, wherein each group input unit comprises and presses five keys that previous embodiment makes up. Wherein first group of input unit is used for the input initial consonant, and the second input unit is used for the input simple or compound vowel of a Chinese syllable. For ease of explanation, the 5th key in first group of input unit is also referred to as " L " key, the 5th key in second group of input unit is also referred to as " R " key.

The large and difficult characteristics of remembering of amount in view of the Chinese phonetic alphabet, in the utility model, the applicant is in conjunction with the unique features of the utility model keyboard, existing initial consonant table and simple or compound vowel of a Chinese syllable table for study rearranged, thereby become relative simple so that remember initial consonant in conjunction with keyboard of the present utility model with simple or compound vowel of a Chinese syllable, and and then improved the efficient of Chinese character input, the below specifically illustrates.

" Xinhua dictionary " inner initial consonant, simple or compound vowel of a Chinese syllable table are rearranged

We see the initial consonant table in " Xinhua dictionary " inner Scheme for the Chinese Phonetic Alphabet first

b	p	m	f	d	t	n	l
								g	k	h		j	q	x
zh	ch	sh	r	z	c	s

It has three row, eight row, 8 initial consonants of the first row, and 6 initial consonants of the second row, 7 initial consonants of the third line are totally 21 initial consonants. If we take out initial consonant r from the third line, the initial consonant table of three row has just had about one symmetrical relation. Because simple or compound vowel of a Chinese syllable can consist of separately a syllable, when the independent syllabication of simple or compound vowel of a Chinese syllable, we also treat initial as initial consonant, the syllable of a, o, e shares initial consonant a, the initial consonant table basis inner at " Xinhua dictionary " increases delegation's (fourth line), a, r, w, y are put into this delegation, consist of the new initial consonant table of a four lines eight row. This initial consonant table has a main feature: the first quantity to initial consonant left and right sides initial consonant centered by the 5th row line of the third line is symmetrical. The main purpose of doing like this is to allow initial consonant and new keyboard form very regular, as to need not to remember a mapping relation.

The key combination of keyboard and the corresponding relation of initial consonant

Symmetrical about the first three rows of new initial consonant table, 433 symmetric relations are quantitatively arranged. We see that 1 key of keyboard makes up 4, and 2 keys make up 6, quantitatively can be assigned as 433, the initial consonant on the corresponding new initial consonant table left side, add the 5th switch " L " that easily triggers, initial consonant that just can corresponding new initial consonant table the right, 4 remaining initial consonants are next corresponding by the combination of 3 buttons. So the initial consonant on key combination, arrangement and the initial consonant table of keyboard puts in order and has formed very regular a, mapping one to one and concern.

It seems more in disorder, and memory is also relatively more difficult. The simple or compound vowel of a Chinese syllable of first row has 12, with 5 of a beginning, and 3 of o beginning, 4 of e beginning. The letter of seeing first it forms: 1 letter forms 3 (each one of a, o, e), 2 letters form 6 (3 of a beginning, 1 of o beginning, 2 of e beginnings), 3 letters form 3 (a, o, e beginnings each 1). Divide in quantity with the simple or compound vowel of a Chinese syllable of (a, o, e) beginning in other words that to mix be inhomogeneous. But by carefully observing, a letter and just very regular (a, o, e) three letters, (ang, ong, eng), look at that again two letters form simple or compound vowel of a Chinese syllable, with a beginning with the e beginning a rule (ai arranged also, an), (ei, en) but with many ao of a beginning. There is an alphabetical o ao the inside, and only has an ou with the simple or compound vowel of a Chinese syllable of two letters of o beginning, if we are referred to simple or compound vowel of a Chinese syllable ao with o beginning simple or compound vowel of a Chinese syllable the inside, also regard the simple or compound vowel of a Chinese syllable with the o beginning as, then the simple or compound vowel of a Chinese syllable of a, o, e beginning has quantitatively just equated, 4 of a beginnings, 4 of o beginnings, 4 of e beginnings, wherein a and e simple or compound vowel of a Chinese syllable letter composition is very regular, all is a, e and (i, n, being combined to form ng) only has this rule that do not meet that 2 letters of o beginning simple or compound vowel of a Chinese syllable form. Again put in order by the order of the order of a, o, e and a letter, two letters, three letters and to arrange, whole simple or compound vowel of a Chinese syllable table is just much regular, simple or compound vowel of a Chinese syllable monogram and arrangement along all very regular, remember also easier.

The key combination of keyboard and the corresponding relation of simple or compound vowel of a Chinese syllable

Two row of new simple or compound vowel of a Chinese syllable table quantitatively are 16 and 16 symmetric relations, totally 32. 4 buttons of keyboard have 16 kinds of combination modes to add that 1 the 5th switch " R " that easily triggers then has 32 kinds of combination modes, quantitatively just satisfies requirement. We are divided into 4 groups with the combination of 4 buttons first, 1 button be combined as first group, 2 combinations (41,12,23 that the button sequence number is adjacent, 34 notes: 41 is end to end in the sequence number cycle chain, it is adjacent to regard sequence number as) be second group, 3 buttons be combined as the 3rd group, empty by (4 button all not according to) 1,2 combinations (13 that the button sequence number is separated by, 24) 2,1 of the combination of 4 buttons is the 4th group. By the sequencing of grouping and the one to one mapping relation of simple or compound vowel of a Chinese syllable formation of new simple or compound vowel of a Chinese syllable table the first row. Above-mentioned key combination adds that the capable simple or compound vowel of a Chinese syllable of the 5th switch and new simple or compound vowel of a Chinese syllable table the second forms one to one mapping relation, asks for an interview following table five.

Through after the above-mentioned processing, more than initial consonant, simple or compound vowel of a Chinese syllable table are regular on arranging, and the quantity of key combination, order also are regular with the alphabetical quantity of initial consonant, simple or compound vowel of a Chinese syllable, the relation of order. Such as:

Initial consonant part: the corresponding initial consonant (b, p, m, f, d, t, n, l) of the combination of 1 key, the combination of 2 keys corresponding (g, k, h, j, q, x, zh, ch, sh, z, c, s), the combination of 3 keys corresponding (aoe, r, w, y). Simple or compound vowel of a Chinese syllable part: simple or compound vowel of a Chinese syllable (a, ai, an, the ang of the corresponding a beginning of 1 key combination (first group), ia, iai (i), ian, iang), simple or compound vowel of a Chinese syllable (o, ou, ao, the ong of the corresponding o beginning of 2 key combinations (second group), io (u), iou, iao, iong), simple or compound vowel of a Chinese syllable (e, ei, en, the eng of the corresponding e beginning of 3 key combinations (the 3rd group), ie, iei, in, ing), the simple or compound vowel of a Chinese syllable (ua, uai, uan, uang, ue, ui, un, uo) of the 4th group of corresponding u beginning.

Annotate: the processing of special simple or compound vowel of a Chinese syllable: more than 32 at " Xinhua dictionary " inner simple or compound vowel of a Chinese syllable. Because 26 English letters do not have ǚ, we replace ǚ with v, and most Pinyin Input methods also are such processing. The simple or compound vowel of a Chinese syllable that ǚ is capable when the front does not have simple or compound vowel of a Chinese syllable, is write as yu (circuitous), yue (pact), and yuan (injustice), yun (swooning), 2 omissions on the ǚ become alphabetical u. With initial consonant j, q, 2 when x pieces together on the ǚ are also omitted, also become alphabetical u. But with n, l can not omit when piecing together, and at this moment goes to replace it with alphabetical v. So meet initial consonant n, in the time of l, as the special circumstances specially treated, nv, lv be not because initial consonant n, l have nui, lui, so simple or compound vowel of a Chinese syllable v is placed on the position of ui, nve, lve be not because initial consonant n, l have nue, lue, so simple or compound vowel of a Chinese syllable ve is placed on the position of ue yet. Since ve and ue pronunciation relatively near outward appearance also relatively as, so need not to go especially memory, need remember that these two syllables of nv, lv get final product. Simple or compound vowel of a Chinese syllable er is not also 32 simple or compound vowel of a Chinese syllable the insides, but simple or compound vowel of a Chinese syllable ong can not form separately syllable, so ong becomes simple or compound vowel of a Chinese syllable er at zero initial (aoe) row simple or compound vowel of a Chinese syllable, simple or compound vowel of a Chinese syllable ueng and initial consonant (b p m f d t n l g k h j q x zh ch sh z c s r) do not consist of any syllable in that " Xinhua dictionary " is inner, when forming syllable separately, u is write as w and is become weng, can so see, in syllable commonly used, there is not this simple or compound vowel of a Chinese syllable of ueng, in new simple or compound vowel of a Chinese syllable table, uo is put into this position, two row simple or compound vowel of a Chinese syllable symmetries will be very carefully and neatly done, this shows＜Xinhua dictionary〉inner all syllables have had unique corresponding relation in keyboard. More than 420 pinyin syllable only has nv, lv, and these three syllables of er need be remembered, the memory amount greatly reduces with originally comparing, even so to say that in the numerous language in countries in the world, only have the syllable of the Chinese phonetic alphabet just so regular, the difficulty of learning Chinese phonetic reduces greatly.

Thus, the keyboard that utilizes above-mentioned code bit to consist of can pass through spell Chinese character input with being easy to, does not need prior art need to switch like that to phonetic Chinese character input method and could realize the Chinese character input.

In addition, it is desirable to be pointed out that, although propose to adopt in the present embodiment two groups of input unit to be respectively applied to initial consonant in the Chinese phonetic alphabet and the input of simple or compound vowel of a Chinese syllable, but consider that present for example double-spelling Chinese character input method is that each simple or compound vowel of a Chinese syllable is the characteristics that replaced by each initial consonant, the utility model certainly also just can only adopt an input unit and this input unit to comprise at least five key switches and carry out Chinese character input method, and about the same with common Chinese double-spelling input method input mode. For example, with reference to table four, key mapping code ' 13 ' expression initial consonant ' h ', but key mapping code ' 13 ' can be set equally represents simple or compound vowel of a Chinese syllable ' ang ' simultaneously. Therefore, when the user wished to input Chinese character ' boat ', he just can press first first and third key simultaneously with input initial consonant " h ", and then pressed first and third key with input simple or compound vowel of a Chinese syllable " ang ", just can input thus the Chinese character with ' hang ' pronunciation.

In fact, any input method of the prior art all can combine to reach with keyboard of the present utility model the purpose of inputting at high speed Chinese character on subminiaturized keyboard.

[embodiment 7]

Present embodiment and embodiment six similar parts are being located, adopt the code bit mapping relation of each key in identical new initial consonant table and the first input unit and the code bit mapping relation that new simple or compound vowel of a Chinese syllable table and second is inputted each key in the unit, difference locate each the input unit also comprise the 6th key, namely each input unit comprise embodiment 5 disclosed press-key structures. For ease of be combined explanation with its function that hereinafter will describe, now the 6th key in the first input unit is designated as " ld ", the 6th key in the second input unit is designated as " rd ". Because the Chinese phonetic alphabet has four tones, so the utility model is by providing two tone switch ld, and rd reduces the repeated code of phonetic; And in the occasion with phonetic synthesis, these two tone switches are set are conducive to correct voice output. Can see that 12 keys have code bit 2¹²=4096, and Chinese phonetic band accent takies 24 * 32 * 4=3072 code bit, therefore, the utility model utilizes the keyboard of 12 keys and has realized more accurately pinyin input mode.

Exist in addition, the 6th in the present embodiment is strong can also to be replaced with obliquity sensor, thereby selects to export the tone of the Chinese phonetic alphabet of expectation according to the rotation of holding the hand of holding keyboard. So can in the situation that does not increase the finger burden, accelerate Chinese character input speed.

In addition, one as present embodiment becomes example, keyboard of the present utility model can also be arranged to three input unit A, B, C, wherein first-selected according to the input of number of keys (or quantity of equivalent keys) Chinese and English: 5 keys/every input unit, Pinyin Input needs two input unit A, B, and the C unit is made of 2 buttons " ld ", " rd ", is used for inputting tone. So such keyboard combination is divided into three part A unit (initial consonant), B unit (simple or compound vowel of a Chinese syllable), C unit (tone), wherein the A unit has 2⁵=32 code bits, the B unit has 2⁵=32 code bits, the C unit has 2²=4 code bits, three unit combination always have 32 * 32 * 4=4096 code bit. And phonetic band accent needs: 24 * 32 * 4=3072 code bit. And for the required code bit of traditional 101 keyboards:

English capital and small letter needs: 2 * 26=52 code bit

Arabic numerals need: 1 * 10=10 code bit

Usual function keys needs: 1 * 15=15 code bit

The Chinese punctuation mark needs: 1 * 32=32 code bit

English punctuation mark needs: 1 * 32=32 code bit

F1 ~ F12 needs: 1 * 12=12 code bit

Shift Ctrl Alt needs: 1 * 3=3 code bit

Shift Ctrl Alt combination need 8 code bits again with 26

Monogram needs: 8 * 26=208 code bit

Therefore, altogether need for finishing above-mentioned input information: a 3072+52+10+15+ 32+32+12+3+208=3436 code bit.

Residue: 4096-3436=660 code bit

(annotate: because new keyboard need not when capital and small letter mixes input by what perform shift key or caps lock key, so this key of Caps Lock just can not wanted. )

Thus as can be known, all be a Key stroke with such keyboard combination input Chinese and English, Arabic numerals, Chinese and English punctuate, usual function keys, key combination commonly used, need not to switch, therefore can replace traditional PC keyboard fully, greatly facilitate the user.

Can control the A unit with a finger when carrying out the Chinese and English input with such keyboard combination, a finger control B unit, a finger control C unit.

Characteristics when input Pinyin is followed Chinese punctuation mark are: A, B, three unit of C are all used, and are special cases when only having simple or compound vowel of a Chinese syllable to be ua, and B does not use the unit (empty pressing).

Input English capital and small letter and the characteristics of numeral when adding a decimal point are: the B unit adds the first key of C unit, and the A unit air is pressed.

The characteristics of input function key are: the B unit adds the second key of C unit, and the A unit air is pressed.

The characteristics of input english punctuation mark are: the B unit adds first, second key of C unit with pressing, and the A unit air is pressed.

Input a large feature that English capital and small letter and numeral add a decimal point, function key, english punctuation mark and be exactly the B unit and add the C unit and get final product, the A unit need not move, and follows Chinese boundary line very clearly demarcated.

The characteristics of the input of combination key are: A, B, three unit of C are all used, because 24 code bit phonetic initial consonants of A unit take, can add B unit, the solution of C unit by the remaining code bit in A unit.

In addition, it needs to be noted, recited above is to input with three fingers of a hand in general occasion, need the at a high speed occasion of input at some, can increase by 3 same input unit operates by another hand, two hands are inputted simultaneously, once just can input two syllables, and speed doubles.

Pinyin coincident code select the word problem

In view of the characteristics of the Chinese phonetic alphabet, namely under same phonetic, a plurality of Chinese characters may be arranged, conventional keyboard can only be selected word with alpha-numeric keys or several punctuation marks keys, has the key of 26 letters can not be used for selecting word, otherwise the logic confusion can occur. But new keyboard can be used to select the character of word a lot, because new keyboard need not switch when the input Chinese and English, when in candidate's window of input method software Chinese character being arranged, can input English upper and lower case letter or Arabic numerals and select word. For example, the phonetic transcriptions of Chinese characters of supposing input is " tian ", the corresponding Chinese character that then occurs on the screen is " 1 day 2 add 3 fields 4 sweet ", then can utilize the predetermined digital code bit as in the second input unit to select the Chinese character of expecting, as when wishing choosing " field ", then can directly press again " 513 " code bit (be first and second, five keys) of the second input unit and directly select.

In addition, it needs to be noted, the keys arrangement of keyboard of the present utility model when the phonetic in when Chinese input and English letter and number is not limited to above-mentioned each preferred embodiment of the present utility model, can in concrete the application, freely limit each key mapping with etc. the corresponding relation of input message.
