Embodiment
Fig. 1 is the composition synoptic diagram of braille-Chinese contrapositive editing and type setting of the present invention.This braille-Chinese contrapositive editing and type setting comprises the braille input media that the blind man user uses; The Chinese character document is converted into automatically the blind automatic switch of the Chinese of braille document; The braille document is converted into automatically the blind Chinese automatic switch of Chinese document; Braille-Chinese contrapositive editor, modification are provided and show the braille proofing of output function according to form in real time; Obtain various operations, editing mode and document content and be converted into voice output shows device to audio amplifier or point Voice Navigation device; Printer and braille imprinter with the output of the content of editing and composing; Display with document content, the instant output of edited result; Help blind person's operation, various operations, editing mode and document content are converted into the apparent device of point that ASCII character is exported.Wherein the braille-Chinese contrapositive proofing is the core of total system, it can be ordinary individual's computing machine of a configuration Windows operating system, above-mentioned braille input media, the Chinese/blind automatic switch, Voice Navigation device, printer and imprinter, display, point show device and all are connected with this braille-Chinese contrapositive proofing by interface general on the computing machine such as serial ports, parallel port, LPT etc., and this braille input media is connected with computer keyboard, and the Voice Navigation device is connected with audio amplifier.
Above-mentioned braille input media is used to solve the information typing problem of blind users.In this device, embedded Chinese braille input method, braille, blind-Han, English, braille-ASCII, blind-input methods such as Ying, can compatible Taiwan braille, Two bors d's oeuveres braille, existing zonal harmonics partly be with the accent braille.Because the blind input method of the Chinese based on phonetic, can realize the input of Braille easily by phonetic.
This braille input media is when using the blind input method of the Chinese, in case user's input is no more than the phonetic of 6 characters, the blind input method device of the Chinese arrives the writing window with the input operation echo that obtains; In case after the user imports tone (0,1,2,3,4), input method will think that the pinyin string input operation finishes, will search the transformation warehouse of braille to phonetic this moment.If a Chinese phonetic alphabet syllable can be formed in the letter of being imported, input method should be imported syllable automatically and convert braille to and output to editor.For making things convenient for blind person's use, the blind input method whole process of this Chinese is converted to sound to the input content immediately with reading keyboard operation, and the blind man user selects suitable Chinese character or braille, thereby is very easy to user's use.
The blind automatic switch of the Chinese that uses in the native system is the device that the inventor independently develops.The Chinese participle technology that it is disclosed based on Chinese invention patent ZL 96100831.8, according to part of speech the braille combination handwriting rule is configured to the combination handwriting rule storehouse, adopt statistical method to set up braille word link writing statistical form, thereby realize the conversion between Chinese to four kind of the Chinese braille (prevailing mandarin braille, Two bors d's oeuveres braille, national language braille braille and Guangdong language braille).The blind automatic translation conversion method of the Chinese that this device uses has been applied for Chinese invention patent (number of patent application: 200410046066.0), can find the detailed description of this technology, just not give unnecessary details at this in its instructions.
Braille adopts based on Markov (Markov) model of adding up to the Chinese automatic switch, in the candidate Chinese character matrix, search for optimal path with Viterbi (Viterbi) algorithm, thereby solve the correspondence problem of braille pinyin string and a plurality of candidate Chinese characters, realize the automatic conversion of braille to Chinese character.Its course of work is as follows:
1) according to the braille word string of input, search braille phonetic contrast storehouse and braille phonetic-Chinese phonetic alphabet contrast storehouse, the braille word string is converted to Chinese phonetic alphabet word string;
2) search Chinese-character phonetic letter contrast storehouse, braille participle dictionary and user thesaurus, obtain the candidate Chinese character vector of each braille, form the candidate word grid by Chinese phonetic alphabet word string;
3) search in abutting connection with Word probability statistics storehouse, in the candidate word grid, search for the path of a probability maximum, thereby generate Chinese sentence with the Viterbi algorithm.
, adopt the Markov model based on statistics that the corpus statistics is obtained in abutting connection with Word probability statistics storehouse here, it is looked Chinese sentence and obeys the Markov model, the probability of happening of promptly next Chinese character state only with its before 1 or n-1 Chinese character relevant.And the Viterbi algorithm is a kind of dynamic programming algorithm, and it is presented as in the transfer process that realizes from the braille to the Chinese character and searches for an optimal path fast from grid.This search is divided into forward direction and back to two processes, in forward process, calculates by the optimal path of initial node to each node with its, and preserves this optimal path.In process, oppositely draw the optimal path of whole grid according to the result who preserves in the back with it.
By blind automatic switch of the above-mentioned Chinese and blind Chinese automatic switch, can at any time Chinese be converted to braille, also prevailing mandarin braille, Two bors d's oeuveres braille can be converted to Chinese and edit simultaneously.This becomes quite simple with regard to feasible edit-modify to braille.System not only can full text translation, can also realize the part translation of article by instant translation system, revising under few situation like this, needn't all want all to translate again at every turn and can just translate that part of having revised, saving time and efforts.The process of translation is finished automatically by computing machine, need not artificial participation, and this has improved several times than traditional human translation efficient, has saved lot of manpower and material resources.
This braille-Chinese contrapositive editing and type setting also is equipped with the Voice Navigation device.The effect of this Voice Navigation device is screen message, slot man content of operation are sent to the synthetic corresponding voice output of voice server or send a little apparent device output to by the screen message acquisition module, the realization automatic speech is followed and Voice Navigation, thereby makes blind person freely operational computations machine and this publication editing system.

This Voice Navigation device not only is suitable for braille-Chinese contrapositive editing and type setting of the present invention, and is suitable for Word, Excel, PowerPoint, application software such as Internet Explorer, Acrobat.It can read aloud on the computer screen all of current active window or specific Word message, and can application programs and window control.It reads the content etc. of dialog box, prompting and the activator button of text in the current proofing, ejection, when cursor moves, reads the information of reposition such as current line, present segment, current word etc.It also has function of reading aloud in full.When the blind person needs to read aloud automatically in full, at first obtain the current active document, it is first then cursor to be moved to literary composition, obtain first sentence text reading, after these sentences and phrases are intact, cursor is moved to next sentence, obtain next content and read aloud, so just can realize in the composing device that cursor is followed automatically in full to read aloud.Read aloud by screen and can make blind users operate the slot man device of this system easily, freely mouse beacon, keyboard are realized conversion, editor, check and correction and the output of braille.
Output unit in the native system comprises a little apparent device, printer and braille imprinter.The apparent device of point is to be used in the equipment that shows institute's content of edit and state in the editing and composing process.It is a standard braille ASCII character with the content and the format conversion of editing and composing, shows on the device at point to be shown as braille again.Blind users can be touched the braille that shows on a little apparent device, perception edit file quickly with hand when listening voice suggestion.The braille imprinter is that braille publishing is printed needed special-purpose braille printing device.Native system can directly be converted to ASCII character with the braille document, and the braille file that forms mint-mark is exported to imprinter, as shown in Figure 2.
The core of this braille-Chinese contrapositive editing and type setting is the braille-Chinese contrapositive proofing.This device not only possesses the general utility functions that the plain text editing machine is possessed, but also can first prohibit then according to the row of braille, end of line is prohibited then, prohibit then the beginning of the page, page footing is prohibited then, the consecutive numbers of changing one's profession rule etc. is carried out automatic typesetting to the braille text, the synchro edit function of braille-Chinese contrapositive document is provided simultaneously, is the text editing apparatus that function is quite perfect, be convenient to manipulate.This device adopts the distinctive braille-Chinese contrapositive editing/typesetting method of native system when carrying out text editing, can realize that the composing of " What You See Is What You Get " shows and the intelligence check and correction.
Above-mentioned braille-Chinese contrapositive editing/typesetting method comprises the steps: as shown in Figure 3
(1) be the storage inside form with braille-Chinese contrapositive document or pure braille document storing;
(2) be automatically converted to paging according to the composing rule and divide row format;
(3) content in the editing machine is inserted synchronously, revised and editing operation such as deletion;
(4) in display, show braille-Chinese contrapositive composing result in real time, provide the braille-Chinese contrapositive form according to customer requirements;
(5) edited result is carried out the intelligence check and correction;
(6) edited result is outputed to printer or imprinter.
In above-mentioned step (3), (4), (5), the result of editing and composing shows in display in real time, and can externally export by printer or imprinter at any time.In step (4) and (5), the user can carry out manual intervention to the process of editor and check and correction at any time by user interface.
In above-mentioned step (1), so-called storage inside form is according to the characteristics of braille and the editing and composing functional requirement of editing machine, formulates with reference to present popular editing machine simultaneously.This storage inside form has adopted the storage format of different levels such as document, paragraph, word to the braille document.For document, paragraph, each level all has the attribute of oneself, is used to be provided with the form of this part when editor, composing, demonstration.
The attribute of document mainly comprises: the printer paper size: be mainly used in normal printer and demonstration, margin: comprise upper and lower, left and right, Doctype: comprise that Chinese document, part band are transferred the prevailing mandarin braille document, all band is transferred prevailing mandarin braille document, Two bors d's oeuveres braille document, braille-Chinese contrapositive document, wherein the braille-Chinese contrapositive document also comprise braille at last and Chinese at last dual mode, page size: i.e. page or leaf line number and capable number formulary.
Section attribute mainly comprises page number setting and disconnected line mode setting, and wherein page number setting can be provided with verso and whether shows whether the page number, recto show whether the page number, the page number account for the alignment thereof of the position of delegation, the page number, the page number, the digital format of the page number, the first page number of this joint separately; The disconnected line mode of braille can adopt three kinds of modes: the disconnected row of short side, the disconnected row of syllable, add conjunction symbol, the disconnected row of syllable, and do not add the conjunction symbol; According to these three kinds of disconnected line modes, when being carried out automatic typesetting, braille can take different modes.
Whether the section attribute mainly enter a new line before the alignment thereof, section of the section of comprising, section after whether enter a new line, first trip indentation, reversion indentation; Also comprise paging rule with the period attribute.Each section comprises concrete content of text.
In the above-mentioned steps (2), format convention is meant that the composing rule according to braille converts a braille document to paging automatically and divides row format, promptly forms clear and definite page or leaf, row structure, carries out page by page line by line demonstration or output such as mint-mark according to the page or leaf row structure that forms again.
One piece of braille may comprise different joints, i.e. front cover, catalogue, text etc., and these different joints have different page number settings and disconnected line mode respectively.According to the composing rule of text, for different joints, implement different disconnected line modes and page number setting, just can obtain different typesetting formats.
Braille text composing rule mainly comprises the page or leaf taboo then, and row is prohibited then.Wherein comprise in detail:
Prohibit then the beginning of the page:
The null (soft null) that the beginning of the page occurs should be implicit with it, can select the somewhere not implicit, and default value is: implicit.Implicit null need not be exported, but should move with content, when not being expert at head, export.
25 solid lines of ten sides (when being in the beginning of the page, should imply) placed in the middle.Move with content, when not being expert at head, should export.
Ten sides, 5 pecked lines (when being in the beginning of the page, should imply) placed in the middle move with content, when not being expert at head, should export.
Expression is every " * " of boundary effect in the literary composition, null (when the beginning of the page, should imply) not up and down, and move with content, when not being expert at head, should export.
Page footing is prohibited then:
All centred headings all can not be put at the page or leaf end, if just in time catch up with at the page or leaf end, title should be moved to down one page.Vacant with the soft return filling, export.But along with moving of content, the effect of soft return will disappear, and follow-up title should follow up.
Separatrix between text and the note (10 top lattice 25 points) can not be put at the page or leaf end, if just in time catch up with at the page or leaf end, and should be with one page under the dislocation of separatrix.Vacant with the soft return filling, export.But along with moving of content, the effect of soft return will disappear, and subsequent content should follow up.
Row is first to be prohibited then:
The head that is expert at can not appear in FollowingPunct.Comprising: comma, pause mark, branch, colon, fullstop, exclamation, back twoly draw, after singly draw, title, back parenthesis, right square bracket, separation dot in the back title, back.If just in time catch up with the head that is expert at, if syllable dislocation next line in speech before its punctuate or the speech with syllable dislocation next line, should should be added consecutive numbers (36 points, soft consecutive numbers) before syllable, when syllable moves, the effect of soft consecutive numbers will disappear.
Row head can not separate syllable, if the head that is expert at just in time caught up with in half syllable in back, should be with first half (being whole syllable) the dislocation one's own profession of its syllable, and before syllable, add consecutive numbers (36 points, soft consecutive numbers).
The space of playing the participle effect in the literary composition head (soft space) that occurs being expert at should lie in it end of line (optional), and (optional) do not exported in not occupy-place (optional), but moves with its content, leaves row when first, and system should become it again hard space, occupy-place, output.
End of line is prohibited then:
The end of being expert at can not appear in leading punct.Comprising: precedingly two draw, precedingly singly draw, preceding title, preceding in title, preceding parenthesis, preceding square bracket, range number, black matrix font size, mark of emphasis, Latin alphabet capitalization number, letter number, line under or beside a word to show that it is a proper noun, dash.If just in time catch up with the end of being expert at, should be with the descending head of its dislocation.
The row end can not separate syllable, if preceding half syllable just in time catches up with the end of being expert at, should be with first half (being whole syllable) the descending head of dislocation of its syllable, and before syllable, add consecutive numbers (36 points, soft consecutive numbers).
Type page:
The horizontally-arranged default value is 30 sides (adjustable), and vertical row's default value is 20 five-element (adjustable).Every row should be arranged full as far as possible, must not super side be out of the line.
The last short side of row is disregarded capable number formulary (optional), and when not counting, not occupy-place should be implied, and does not export.During counting, not occupy-place, not implicit, export.
Above-mentioned format convention has special embodiment in the braille-Chinese contrapositive document.The braille-Chinese contrapositive document is a kind of special braille document format, and each group contrast text has triplex row, and wherein delegation is that braille, delegation are that Chinese, delegation are the nulls that is used to separate usefulness.Its special character is: each group speech that braille is capable and Chinese is capable also needs separately and align center shows output.Therefore, document inside also needs particular processing for the braille-Chinese contrapositive document, each section all is made up of two parts, wherein one section is that braille section, another section are the Chinese sections, and braille section and Chinese section all must be separated each speech with special symbol, the word sum that guarantees braille section and Chinese section simultaneously in editing process is consistent, has guaranteed the integrality of braille section and Chinese section contrast like this.
Carrying out braille when handling in lines, the disconnected line discipline of the attribute of the foundation section of comprising of branch, document properties and user's setting.Section attribute and page setup be existing explanation in preamble, no longer repeats at this.
Disconnected line discipline is relevant with different braille types and different sign, according to prevailing mandarin braille scheme and Two bors d's oeuveres braille scheme, we are by summing up the composing rule of braille, and draw the disconnected line discipline of braille: current location meets end of line and prohibits then, next position meets the first taboo of row then, and row then can break.Specific explanations is as follows:
1) the current location end of line that should meet is prohibited then:
● current is short side, and row can break;
● current location is a leading punct, and row cannot break;
● syllable can not be separated.
What 2) next position should meet goes first the taboo then:
● not FollowingPunct;
● syllable can not be separated.
In the process of braille editing and composing, this braille-Chinese contrapositive editing and type setting also provides splits type-setting mode.This is split and sets type is peculiar mode during braille is set type, and as shown in Figure 4, about mainly being meant in the braille publishing thing relative two pages, delegation's content corresponding in the delegation in the verso and the recto is continuous, and just each full line all is divided into reciprocity mutually two capable.
In order to realize the distinctive type-setting mode of this braille, we have adopted OO to the game clock technology, promptly the content of setting type are inserted in the form of splitting, and then form are embedded in the document as object, split typesetting format thereby form.
In the step of this braille-Chinese contrapositive editing/typesetting method (4), the braille-Chinese contrapositive document is inserted, revises and operating process such as deletion in, editing operation to Chinese character or braille all can have influence on its corresponding braille or Chinese character, system can automatically revise, show current operating result in real time, as Fig. 5 shows.
The said intelligent check and correction process of step (5) in commission can generate form as shown in table 1:
| Sequence number | The original text page number, the row number | New civilian page number, the |
| 1 | ||
| 2 |
Table 1
Automatically the change content after marking original text in this form and proofreading change in the article is the position in original text and check and correction article respectively, the Chinese braille contrast file of sentence alignment form can also be saved in assigned catalogue simultaneously, the blind person press corrector just needn't proofread in full once more again like this, thereby improve the efficient of check and correction greatly, reduce the workload of blind person's check and correction.
In the process that intelligence is proofreaded, as shown in Figure 6, the content of selected errors present can appear in the original text frame of check and correction window automatically, only need import correct content in correction literary composition input frame, can finish a place and change work.After all the elements check and correction was finished, the full content of correction all was updated to correct content, and the content of wrong content and corrigendum is stored in the document, and had kept page number after the former page number that is modified the place, row number and the corrigendum, row number.This function greatly facilitates the user of native system.
Above braille-Chinese contrapositive editing and type setting of the present invention and editing/typesetting method are had been described in detail, but obvious specific implementation form of the present invention is not limited thereto.For the those skilled in the art in present technique field, the various conspicuous change of under the situation of spirit that does not deviate from the method for the invention and claim scope it being carried out is all within protection scope of the present invention.
