Nemetex Nemeth Back-Translator Version 2.3.1 User's Guide

Nemetex Nemeth Back-Translatorä affords an easy way to print Nemeth Braille Math that was typed on an electronic Braille notetaker and print it in plain typeset such that parents, teachers or peers of visually-impaired mathematicians could read it. Without AccessiSoft's Nemetex Nemeth Back-Translatorä, someone, typically a Braille Transcriber, must painstakingly inter-line every piece of math homework, project, paper, or test created in Nemeth. The Nemetex Nemeth Back-Translatorä uses a unique process to examine the content, identify it as either Nemeth or normal text, and convert it into LaTeX so it can be read by any standard LaTeX-based editing program, such as TeXnicCenter. The resulting file could, depending on the LaTeX program in use, then be hard-copy printed in normal printed math or saved to a Portable Document Format (PDF) file for electronic transfer via e-mail or posting/sharing with sighted users.

Nemetex Nemeth Back-Translatorä Version 2.3.2 includes all mathematics through Algebra II, Geometry, Trigonometry and pre-Statistics and pre-Calculus, so it will accommodate the math work of students from the elementary through the high school level. Ultimately, AccessiSoft plans to expand the capabilities of the program into College and then Advanced Professional Editions. The Nemetex Nemeth Back-Translatorä is also fully-compatible with JAWS^Ò for Windows^Ò and Window-Eyesä screen readers (32-bit operating systems only) so that visually-impaired authors of math can use it by themselves or with the help of a sighted transcriber. Key benefits include:

· Runs on Windows-based PCs tested through Windows 7^Ò (no MAC version available);

· Screen-readable by JAWS^Ò for Windows^Ò and Window-Eyesä;

· Runs on any Java-compatible PC;

· Outputs in LaTeX so that files can be subsequently opened in or imported into any standard LaTeX-based publishing/editing software;

· Converts a mix of Nemeth Braille Math and regular text in the same file;

· Works with various types of six-key entry-capable Braille Notetakers;

· Effectively handles various types of spatial mathematics such as matrices and multi-line comparisons; and

· Identifies most common input Braille errors and provides a summary of errors which can be saved as a separate file.

Overall Nemetex Back-Translation Process

Figure 1 provides a Flow Chart which depicts the overall Nemetex Back-Translation Process.

Figure 1. Overall Nemetex Back-Translation Process

The process starts with math typed in Nemeth and text in Grade II Braille on a Notetaker. Then, on the notetaker, it is translated to “.txt” file (ASCII). The resulting .txt file is saved to a portable medium or otherwise transferred (hard cable, e-mail, etc.) to the PC on which Nemetex is loaded. Then the file is imported into Nemetex and Nemetex back-translates the file into LaTeX. The file is then saved as a LaTeX “.tex” file directly from Nemetex. The .tex file is then opened into a LaTeX Program (such as TeXnicCenter or Scientific Notebook), converted to .PDF and printed, saved or transferred electronically (depends on program).

Requirements

The computer on which the Nemetex Nemeth Back-Translatorä is to be installed must also be equipped with the following software/hardware:

- Microsoft Windows^Ò Operating System. Version 2.3.2 has been successfully tested using Windows^Ò XP Home, XP Professional, Vista Home Premium and Vista Ultimate PC (64-bit versions) and Windows 7 Home Premium (32- and 64-bit versions).

- Javaä Runtime Environment (1.5.0_01 or later), also known as the "Java Virtual Machine", "JVMä", "VM" or "Java VM" is required, and the latest version is recommended. The currently-installed version can be verified via the web site: http://java.com/en/download/installed.jsp (firewall and/or security software settings may need to be adjusted to allow the verification process to work).

- While a screen reader is not required, the Nemetex Nemeth Back-Translatorä has been tested to be compatible with Window-Eyes™ and JAWS^Ò for Windows^Ò. Appropriate interface software must be installed to ensure the screen reader works correctly with Javaä. At this time, available interface software runs correctly in 32-bit operating systems only. Procedures from Microsoft to determine if your operating system is 32-bit or 64-bit can be found at http://support.microsoft.com/kb/827218.

§ If JAWS^â for Windows^â is to be used with Nemetex, the Javaä Access Bridge For Windows Operating System interface software must be installed (available for 32-bit operating systems only). It can be found for free download at http://java.sun.com/products/accessbridge/ (install the most recent version). The Javaä Access Bridge For Windows Operating System must be installed, or re-installed if previously installed, after installing a Javaä RTE update as discussed in step 3 above.

§ If Window-Eyes ™ is to be used with Nemetex, WE4Java 0.9.19 interface software by Jay Macarty is the recommended application to be installed (available for 32-bit operating systems only). It can be found for free download from GW Micro Script Central at http://www.gwmicro.com/Script_Central/Scripts/Script_Details/?scriptid= 1222 (install the most recent version). WE4Java must be installed, or re-installed if previously installed, after installing a Javaä RTE update as discussed in step 3 above.

- If the Nemetex Nemeth Back-Translatorä program is to be delivered on a Compact Disk, the host computer must have a compatible CD-ROM drive.

- The source ASCII text files which the Nemetex Nemeth Back-Translatorä converts are typically created on a portable Braille electronic notetaker such as a BrailleNote, Braille Sense, or PAC Mateä. Because the Nemetex Nemeth Back-Translatorä program runs on a personal computer, the user must have a means by which to transfer the ASCII file containing Nemeth code to the host computer (Flash Card, Thumb Drive, hardwire, etc.).

- The final output of the Nemetex Nemeth Back-Translatorä program is a .tex file which is then readable by any standard LaTeX-based publishing software program such as TeXnicCenter (see http://www.artofproblemsolving.com/Wiki/index.php/LaTeX:About for information about downloading the most recent versions of both TeXnicCenter and MiKTex), or one of many similar commercial products such as Scientific Notebook (http://www.mackichan.com/). If the desired final output file format is .PDF, a free .PDF reader can be found at http://www.adobe.com/products/acrobat/readstep2.html. Other readers may be available and/or required to view final output files from other LaTeX-based publishing software programs.

File Preparation Methods

There are three different methods for preparing a file for conversion by the Nemetex Nemeth Back-Translatorä. If using a notetaker, such as the BrailleNote, that has a defined command to change the grade of Braille for keyboard entry within a Braille document, Method 1 is recommended. If a notetaker that recognizes the Computer Braille Begin (dots 4-5-6 and dots 3-4-6) and Computer Braille End indicators (dots 4-5-6, and dots 1-5-6) is used, such as the BrailleLite and Braille Sense, Method 2 is recommended. If a notetaker that does not have either of these features is used, Method 3 is recommended.

When writing math in all of the preparation methods, although Computer Braille is the Braille grade for keyboard entry in the file preparation, the math symbols need to still be written using Nemeth dot combinations. Using Computer Braille math symbols instead of Nemeth symbols will sometimes cause the file to translate incorrectly.

Method 1

a. Create an electronic Braille document file. The document file does not need to be a .brf file, but can be a Braille file type specific to the notetaker. Text that does not contain Nemeth symbols and numbers can be written in Grade 2 Braille.

b. Before writing Nemeth symbols and numbers in the document, type the command to change the grade of Braille for keyboard entry to Computer Braille. Change back to Grade 2 Braille before writing any (non-math) text in Grade 2 Braille.

Note: Forgetting to switch back and forth between Grade 2 Braille and Computer Braille can have adverse consequences, such as "y < t" translating as "you know that."

c. Once finished writing in the file, translate it into a text-only file, typically by saving it as a .txt file.

Note: Simply changing the extension of a file from ".brf", ".doc", etc. to ".txt" will not result in a properly formatted Nemetex input file.

d. Transfer the file to the Nemetex Nemeth Back-Translatorä host computer.

Note: One option for file transfer using a BrailleNote is to use e-mail and translate the files upon attachment to the e-mail. Some text files that are translated and attached to e-mails on the BrailleNote may contain extra erroneous characters. To remove these characters, check the "Remove Extra Characters" option in the Translation Options. See Translation Options for more information.

Note: If a section of the document is not marked as computer Braille while writing the file, in some cases, such as when using a BrailleNote, it is possible to mark the entire section and specify it as computer Braille. However, in the conversion, all letters and symbols will be converted to uppercase, which will interfere with the Nemeth to LaTeX translation. Therefore it is recommended that either the section be rewritten or the capitalization is corrected. See Use with the BrailleNote for BrailleNote settings.

Method 2

a. Create an electronic Braille document file. The document does not need to be a .brf file, but can be a Braille file type specific to the notetaker. Text that does not contain Nemeth symbols and numbers can be written in Grade 2 Braille.

b. Before writing Nemeth symbols and numbers in the document, type the Computer Braille begin indicator symbol (dots 4-5-6 and dots 3-4-6). Before writing any (non-math) text in Grade 2 Braille, enter dots 4-5-6 and dots 1-5-6. It is recommended that the file be thoroughly proof-read before translation.

Note: Forgetting to switch back and forth between Grade 2 Braille and Computer Braille can have adverse consequences, such as "y < t" translating as "you know that."

Note: For notetakers requiring Method 2, the character mod setting re-sets are the end of each line and must be re-established at the beginning of each subsequent line. If this proves too cumbersome, Method 3 should be attempted.

c. Once finished writing in the file, translate it into a text-only file, typically by saving it as a .txt file.

Note: Simply changing the extension of a file from ".brf", ".doc", etc. to ".txt" will not result in a properly formatted Nemetex input file.

d. Transfer the file to the Nemetex Nemeth Back-Translatorä host computer.

Note: Method 2 will not work with the BrailleNote.

Method 3

a. Create an ASCII file.

b. Write all words that are not math in Computer Braille, write the Nemeth as Nemeth, and do not use any Grade 2 Braille.

c. Transfer the file to the computer.

File Format

The following input file format conventions, if followed, will make the back-translation process run smoother and reduce the number of translation errors.

a. Leave an empty line before and after each problem. This will help the Nemetex Nemeth Back-Translatorä identify to the user where typographical errors can be found based on problem numbers.

b. Leave an empty line after any headings at the top of the file.

c. The Nemetex Nemeth Back-Translatorä will insert line breaks where they are needed, but it will not split a word or an expression to insert a line break. Therefore, any expressions or words that are more than fifty characters long must have a line break inserted.

d. If the letter "a" or "i" is used as a mathematical variable within a sentence, and it is not immediately preceded or followed by a math symbol, the letter "a" or "i" should be preceded by the letter sign (dots 5-6) in order for it to be recognized as a mathematical variable.

e. See below for special considerations when using a BrailleNote to generate the ASC II file.

[Back to Top] [Back to Nemetex Page]

Spatial Mathematics

This section covers formatting for matrices, sequences, parametric equations, multiplication, division and balanced equations. All of these should have a blank line before and after them, which is the only special formatting required for sequences and parametric equations.

Matrices

The Nemetex Nemeth Back-Translatorä currently supports matrices in which each element is a single word. Elements in the same column in different rows should be vertically aligned to the maximum extent possible (no more than three spaces out of alignment). The Nemetex Nemeth Back-Translatorä supports multiple matrices side by side, with and without symbols between them.

Multiplication and Division

Multiplication and division expressions need to be properly aligned. Note that Nemetex Nemeth Back-Translatorä does not currently fully align multiplication and division containing fractions.

Multi-line Comparisons

For a sequence of comparisons (=, <, >, etc.) on multiple lines, the Nemetex Nemeth Back-Translatorä will horizontally align the comparison signs so that they are in a vertical line. All comparison equations should be preceded and followed by an empty line. The "Align Comparison Signs" Option should be checked in this case.

[Back to Top] [Back to Nemetex Page]

Use with the BrailleNote

The following BrailleNote conventions, if followed, will make the back-translation process run smoother and reduce the number of translation errors.

a. Ensure lines style instead of paragraph style is used such that the file will retain the line breaks when translated into text.

b. Set the BrailleNote Back-Translation Option "Revert to Paragraph Style After How Many Blank Lines" to a value greater than "1" such that switching back to lines style after every problem is not required.

c. Set the BrailleNote ASCII Translation Option "Use Line Or Paragraph Format" to "Lines" and set the "Use End of File Character" option to "Off."

d. File Preparation Method 2 above will not work with the BrailleNote, but Methods 1 and 3 will.

e. Multiplication and division problems must be numbered or lettered. Due to internal settings on the BrailleNote, the actual problem must start on the next line (no empty lines between the number/letter and the problem).

f. The command to change the Braille grade for keyboard entry to Computer Braille in a Keyword Braille document is backspace with dots 2-4-5, and the command to change to Grade 2 is backspace with dots 1-2.

[Back to Top] [Back to Nemetex Page]

Running the Program

When the Nemetex Nemeth Back-Translatorä opens, an empty input text window will appear. The file requiring conversion can either be cut and pasted directly into the window or an existing file can be opened into the window. To open a file, either select Open on the File Menu or press Control-O.

Note: If cutting and pasting is to be used, the input .txt file should be opened in a simple text reading file such as Notepad or Wordpad. If more capable word processing or publishing programs, such as Microsoft Word, are used to open, then copy/cut the data to be pasted into the Nemetex Nemeth Back-Translatorä, the program can insert hidden codes and symbols which will cause anomalies during translation.

To translate the text, select Translate on the Translation menu or press Control-T. A window will then pop-up showing translation progress as a percentage. File translation can take up to several minutes, depending on the length and complexity of the math file.

After the translation is complete, select OK to continue.

Save the translated file as a .tex file or copy and paste the text directly into a LaTeX-based compiler/publishing program such as TeXnicCenter. Some LaTeX-based programs, such as Scientific Notebook, require the converted file to be directly opened and does not accept cutting and pasting content into the program. All required LaTeX headers and footers will already be included in the text.

[Back to Top] [Back to Nemetex Page]

Translation Options

To access the Translation Options, either select Translation Options on the Translation Menu or press Control-P. The Translation Options are:

a. Display On-Screen Instructions. When checked, step by step instructions are displayed on the screen. The default setting is checked.

b. Cut Extra Characters from the End of a BrailleNote File. Sometimes, a BrailleNote will add extraneous characters to the end of a translated text file that has been sent by e-mail. This option removes these characters. The default setting is not checked. If there are no extraneous characters at the end of a translated file, checking this box will not have any negative effects.

c. Number of Paragraphs to Skip at Beginning of Document. As part of the translation, Nemetex Nemeth Back-Translatorä separates the math from the regular text such that regular text does not get inadvertently marked as math. If any headings at the beginning of a document do not contain math symbols or math text other than Nemeth Braille Math numbers, Nemetex Nemeth Back-Translatorä can automatically specify that region as text and skip the demarcation process, reducing the overall translation time. For this setting, a paragraph is defined as a block of text preceded and followed by a blank line (except the first paragraph). The default setting is "0."

Note: If the LaTeX will not compile or returns errors, ensure that the "Number of Paragraphs to Skip at Beginning of Document" is not set too high (higher than the appropriate number of text header paragraphs).

d. Number of Paragraphs to Center at Beginning of Document. Because all formatting is lost in text format, Nemetex Nemeth Back-Translatorä can use the LaTeX language to center the text. The number in this option specifies the index of a paragraph, starting from the top. For example, a value of "2" will center only the second paragraph. To center more than one paragraph, separate the numbers by commas. For example, a value of "2,3" will center the second and third paragraphs. Note that this value cannot be greater than the number of paragraphs to skip at beginning of document (see d. above). See e. above for the definition of a paragraph. The default setting is "0."

Note: The "Number of Paragraphs to Center at Beginning of Document" cannot be set to one.

e. Align Comparison Signs. This setting determines whether or not to align a sequence of comparisons (=, <, >, etc.) on multiple lines. See Spatial Mathematics above for more information. The default setting is unchecked.

f. Set Directory of Current File as Default Directory. This selection toggles between two states. Upon initial installation, the program defaults to the state. In this state, the program will return to the last visited directory when opening an open or save dialogue box. In this state, the toggle button on the Translation Options page will read "Set directory of currently open file to default directory." If this button is selected, the state will change to "Set directory of currently open file to default directory" and the button will then read "Set to no default directory" to offer the other state. The "Set directory of currently open file to default directory" state sets the directory of the currently-open file as the default directory into which Nemetex will look to save or open files the next time the program is started.

Note: Upon initial installation, or if the program has been previously set to the "Set to no default directory", if a file is not open, the toggle button will not appear and "Set directory of currently open file to default directory" will not be offered as a choice.

[Back to Top] [Back to Nemetex Page]

Errors and Error Reporting

Note: Because Nemetex Nemeth Back-Translatorä does not detect all possible input errors, it is recommended that input files be proof-read thoroughly before translation.

Nemetex Nemeth Back-Translatorä can detect and display certain errors in the original input file and report them to the user. Such errors include: missing or double begin or end fraction sign, missing fraction slash, and missing begin or end matrix sign.

Nemetex Nemeth Back-Translatorä will attempt to determine the problem number in which the error is located. If Nemetex Nemeth Back-Translatorä cannot find a problem number associated with a translation error, it will not display one. Attempting to find an error in a large file without problem numbers can be tedious and time consuming, so it is highly recommended that problems are numbered, leaving a blank line between problems.

If no error is immediately evident in the reported problem number, it is likely the error is somewhere before that problem number. The input should be examined upward in the file, starting with the problem prior to the Braille section causing the error. If this does not locate the error, try translating sections of the file separately.

Some of the most common Braille errors that can cause translation errors are missing, incorrectly-written, or extra:

§ Begin or end fraction signs;

§ Fraction slashes;

§ Begin or end matrix signs;

§ Mainline indicators following super or subscripts; and

§ End of square or other root symbols.

Nemetex Nemeth Back-Translatorä has two different error reporting feedback formats:

The first is via an error report file that can be edited and saved. If specific errors are found, an error file will open immediately after pressing OK in the Translation Complete dialog box. The error report file can be saved as a .txt file for future reference, especially if multiple errors were found. Closing the error file will then place the user into the translated file, but it is recommended this file be closed without saving before translating the corrected file to prevent confusion over which translated file is free of errors. When this is closed, the original input file will be displayed for proof-reading and correction.

Note: Nemetex Nemeth Back-Translatorä may report the same error twice with two different messages. If Nemetex Nemeth Back-Translatorä reports two or more errors in a particular problem number, but not all of them can be found, try retranslating the file after correcting whatever errors could be found.

The second error reporting feedback format is a dialog box that is displayed if the translation could not be completed because of a process error, which could have been caused by a fatal error in the input file or possibly by the program itself. In this case, manually proof-read the input file and attempt to re-translate it after correcting any errors found. If the file is large, the file should be separated into multiple smaller portions to help narrow-down the section of the file causing the fatal error.

If no error in the input file can be found, but a fatal program error still occurs, please send the original Braille file (if used File Preparation Method 1 or 2) and the text file to tech.support@accessisoft.com specifying the subject line of the Exit Error.

Known Anomalies

Version 2.3.2 of the Nemetex Nemeth Back-Translatorä has the following known anomalies:

a. Due to a known anomaly when using JAWS^Ò for Windows^Òin Javaä, in the open and save dialogs, JAWS^Ò for Windows^Ò sometimes reads the selected/not selected status of a file or folder incorrectly, especially if the space bar or Control-Space have been used to select or unselect a file or folder.

b. The first time Nemetexä is run after initial installation, or after installing a new version of Javaä RTE, it could take up to a minute to open while Nemetex examines the Javaä files on your computer.

c. In Nemetexä, a colon is always treated as a math symbol when it follows a number and results in back-translation as a number with a line over it (such as "Bar 6" or repeating character). Until this anomaly is addressed in a future program revision, it is best to avoid the use of a colon in regular print following a number in all locations except the area at the top of the page that is designated as non-math (see Translation Options).

d. In accordance with Nemeth Code, Nemetexä always treats a letter followed by a number as math and back-translates the number following the letter as a subscript of that letter. Until this anomaly is addressed in a future program revision, the best work-around is to add a space or a number sign (dots 3-4-5-6) between the letter and the first subsequent number in all locations except the area at the top of the page that is designated as non-math (see Translation Options).

e. Nemetex was originally designed assuming that typical math problem numbering in the document to be translated would be a number or a letter followed by a period at the beginning of a math problem line. While recognition of some hierarchical combination of letters, numbers, periods and parentheses run together can still cause minor translation anomalies (for example, "1.a.(1)(b)(i)" will usually translate with all the letters in italics vice just the "i"), Version 2.3.2 improves the recognition of complex problem numbers. Nemetex will translate most effectively when there is a period or close parentheses after the letter or number occurring at the beginning of a math problem line to clearly delineate the problem number or letter from the math equation itself.

f. If an error report file is generated, Nemetex may report the same error twice with two different messages because the single error triggered two different types of errors for which Nemetex searches. If Nemetex Nemeth Back-Translatorä reports two or more errors in a particular problem number, but a fewer number can be found after thorough proof-reading, try re-translating the file after correcting whatever errors were found.

g. The "Number of Paragraphs to Center at Beginning of Document" cannot be set to one.
