(5) embodiment

The utility model is clicked Hanzi component on the touch-screen by braille pen under the support of two keys intelligence Chinese character input software, just can realize Chinese character input smoothly.

Simply introduce this letter stencil below under the support of intelligent Input Software, how to realize what Chinese character was imported.

1, two key concepts

1. first part: take from the first radical of Chinese character, do not have the first sum of picture of getting of first radical.

2. first part: take from the tail radical of Chinese character, the anury radical get the tail stroke.

Chinese character	Peace	The emblem	Temperature	Fragrant	Recessed	Protruding	Jiang
								First part	Http	Chi	Rui	The scholar	|	|	Lv
Tail piece	The woman	The-Fan	Ware	Day	One	One	Very little

2, braille flow process

1. two Chinese characters with upper-part are arranged

The braille flow process: elder generation's point first part-→ back point tail piece

The Chinese character that 2. parts are only arranged

The braille flow process: earlier the some first part-→ put little space again

For example:

Chinese character	Sign indicating number	Volume	Tree	Warm	The people	One	The worker
								First part	Stone	Car	Wood	Day	The people	One	The worker
Tail piece	Horse	Ear	Very little	Xiangxi	The space	The space	The space

3, split rule

1. get many few rules of not getting

When getting the initial and end parts, should get the maximum parts of stroke among Fig. 2.For example the first part of " mill " is got " extensively ", does not get " Dian ", and tail piece is got stone, does not get " mouth "; The initial and end parts in " spring " are " three, day ", can not be " one, day "; The initial and end parts that " are " are " Pie, yarn ", can not be " Pie, little ".

2. first part priority rules

When initial and end parts commissure together the time, first part has the right of priority of getting stroke more.For example the initial and end parts of " my god, husband " all should split into " two, people ", can not split into " one, big "; The initial and end parts at " noon " are " , ten ", can not be " Pie, dried ".

3. frame rounds rule (frame contains " mouthful Contraband " two parts)

If the first sum of on " mouthful Contraband ", first part should be with they whole taking-ups.The initial and end parts that for example " are stranded " are " mouth, wood "; The initial and end parts of " gangster " are " Contraband, three ".

If the first sum of not on " mouthful Contraband ", the tail pen drops on " mouthful Contraband ", and tail piece also should be with they whole taking-ups.The initial and end parts of example " slaping " are " Rolling, mouths "; The initial and end parts of " basket " are " , Contraband ".

4. the differentiation of five kinds of hooks

Youngster's hook " ": perpendicular turn of bilge position does not have the stroke of friendship, company, bag, and font has " youngster does not have the stream of opinion ... ".

Second hook " second ": upper left quarter has a horizontal stroke to link to each other with perpendicular turn of bilge, and font has " second several nine ... ".

Hand over hook " an ancient type of spoon ": perpendicular turn of bilge has the stroke of friendship, and font has " its residence also electricity gets rid of hair ... ".

The bag hook : perpendicular turn of bilge has the stroke of bag, and font has " oneself clings to the sixth of the twelve Earthly Branches ... ".

Dagger-axe hook " dagger-axe ":

The dagger-axe hook is disregarded horizontal some left-falling stroke, and the font that contains " dagger-axe " hook has " people shoot a retrievable arrow Yao's dagger-axe Jian Yu ... ";

If the first sum of picture is handed on " dagger-axe ", first part should be got " dagger-axe ", example " or " should split into " dagger-axe, ";

If the first sum of picture does not intersect with " dagger-axe ", the tail stroke falls thereon, and then tail piece should be got " dagger-axe ", and the first sum of picture of example " carrying " and the soil phase are handed over, and the tail stroke drops on " dagger-axe ", so the initial and end parts are " soil, dagger-axes ".

4, phrase input (click " phrase " key of Fig. 2 bottom, switch to the phrase input state)

1. four words: the first part of importing four words

Phrase	Extend in all direction	Surge ahead	Assume someone else's authority to browbeat others
				Coding	マ eight is big for mouth	One horse solar month	Quan Ren | dagger-axe

2. multi-character words: the first part of input front-three-end-one

Phrase	The People's Republic of China (PRC)	The Chinese People's Liberation Army	The National People's Congress
				Coding	Mouth Ren population	Mouth mouthful people Mi	Population everybody

The point letter stencil has enrolled more than 100,000 phrase, all is phrase of quadruple linkage input.

5, the input of special symbol (click the " char " key of Fig. 2 bottom, switch to the character input state)

When switching to the input state of special character, screen display is as follows:

1, phonetic alphabet 2, form symbol 3, Russian symbol 4, hiragana 5, Japanese katakana

6, various digital 7, Greek alphabets 8, special symbol 9, sign of operation

The utility model has designed 9 screen special characters, clicks respective digital earlier and selects, and when occurring respectively shielding character, tries to locate by following up a clue and clicks the symbol that needs.

6, the repeated code data of some letter stencil

The point letter stencil is selected 117 parts are put Chinese character of two keys inputs, and the single character code capacity is 117 2 powers, has more than 13600; Phrase of some quadruple linkage input, the phrase code capacity is 117 4 powers, up to more than 100,000,000 2 thousand ten thousand.

The point letter stencil enrolls 6763 Chinese characters in the GB one secondary character library, and the repeated code data of two keys input are as follows:

2 words, 3 words, 4 words, 5 words, 6 words, 7 words, 8 words, 9 words 10 11 12 13 14 15 16 17 18

660 300 157 106 66 34 17 19 15 10 6 7 4 1 1 2 3

One-level brevity code: 117 secondary brevity codes: 3254

From statistics as can be seen, the repeated code that surpasses 11 words only has 24,11 repeated code words of design presenting bank prompting, and having 74 repeated code words can not show at first screen, needs page turning to go choosing.

As seen with this letter stencil input individual character, two keys see that first screen the word rate is up to 99%.

The point letter stencil has enrolled more than 100,000 phrase, owing to be phrase of quadruple linkage input, code capacity surpasses 100,000,000, and the phrase repetition rate of coding only is 0.02%, and promptly the probability of their repeated codes is almost nil.

7, the processing of repeated code words

1. the speech check and correction is selected in intelligent whole sentence input automatically

It is the original input mode of unit that this some letter stencil has been broken away from word, speech, by the analysis to the Chinese grammar and the meaning of one's words, has adopted intelligence to select speech check and correction technology, is that unit imports article with whole word, and discrimination is up to 99%, thus the trouble of having exempted the selection repeated code.

2. uncorrelated individual character need be selected repeated code during input

When the individual character of input no context association, repeated code appears, owing to can not adopt intelligence to select speech check and correction technology, the point letter stencil is presented at the repeated code words in the presenting bank, need select input with braille pen, is triple bond one word at the most, 74 words are only arranged, need page turning to select, they are quadruple linkage one words.
