When you are transcribing a book according to the rules of Braille Formats, those rules take precedence. So you would follow the print copy for capitalization. If all the print paragraph headings are in the same typeface, then you would also italicize the paragraph headings.
Have you considered attending the next NBA Conference in Raleigh, North Carolina on Oct 7-9, 2011, where there will be a comprehensive tactile graphics curriculum?
The University of Washington uses Adobe Photoshop as part of a multi-step process for converting print graphics to tactile graphics intended for printing to puff paper. Dan Comden has given lectures at braille conferences about the software.
Jim Barker, a Specialist at CTEBVI, gives lectures every year at the CTEBVI conference in the spring about using photoshop for tactile graphic production.
As a braillist, I would strongly encourage you to use Illustrator or Corel Draw rather than Photoshop for preparing tactile graphics. Photoshop is really intended for touching up pictures. Illustrator is more of a drawing tool which allows you to create images and add text.
Print graphic images are usually far to complex to be directly converted to tactile graphics. They need to be simplified, in some cases, radically simplified, so that only the essential information is conveyed.
I am wondering what the heirarchy is for dividing such a thing. Suppose that the first equation is long and needs to be divided one or more times. Wouldn't logic dictate that the "expression" should be divided also at the level of the second separate equation, since that is of a higher order even than a sign of comparison?
I think you have a good solution; I can't find anything more appropriate. However, if it is obvious that the two notes are to be played by the thumb (it almost always is), I would supply the first-finger sign after the note and the interval sign as illustrated in MBC Example 14.3.1, since the bracket is vertical instead of horizontal.

Venn diagrams are most often found in math textbooks, where they are showing overlapping data, and often the student is asked to place information within the diagram. This seems to be more simply a comparison of the lives of two individuals. If it is not in a mathematics context, I'm not sure that you would have to create a tactile. Could the information not have been shown in print as a table? Is this just a design technique used in the print edition, or are there questions or information given that indicate it must be shown as a Venn diagram? However, since you have said that you want to include this as a Venn diagram, I have worked out a [u]possible [/u]solution and attached it.
I don't think that mathematically there is any reason why the comparison couldn't be made using a vertical overlap (rather than horizontal). Nor do I think that it is essential for the containers to be perfect circles or ovals. The proposed tactile guidelines do suggest that two different types of lines be used. Creating a key, makes it more difficult for the reader to interpret the graphic. If you were going to use a key, I think that each of the points should be keyed separately, with perhaps the headings in the ovals.
Take a look, and see if you think this might work for you.
BettyIf there is anything present in the division problem besides numbers, decimal points and commas, the division problem would be spatial.
Single capping the letters in this variable implies that each of the letters has a separate identity. This is not the case. FV and PV are abbrevations serving as variables and should be double capped.
I don't believe there is provision in Nemeth for dividing words connected by a slash. The symbol used for a slash in Nemeth is defined in the Nemeth Code as a sign of operation (even though it looks like the literary symbol). Bring the entire expression down to the next braille line. Remember that there are no contractions in words adjacent to a slash.
sorry, I left out "composed entirely of numerals". Maybe this answers the question, but it would be nice to have an example.
I consider this kind of thing to be an author's comment to the equation, in which case I usually place it following on the same line in braille with any runovers in the established runover position. I don't believe there is a rule specifically addressing this situation. If there could be confusion about the "meaning' of this additional material, and it is not differentiated in print with a comma or other punctuation, I have, on occasion, placed a note on the TN page stating that comments to equations or procedures are enclosed in brackets (or whatever) and follow on the same braille line.
The food chain shown could be transcribed as displayed to a main item with subdivsions, which would place it in cell 7. You do need to include "plant caterpillar bird cat" in the question because they consitute the food chain, and are not answer choices. The answer choices are listed following this food chain.
I'm taking the liberty of posting a reply here, since it relates to tactile graphics.
The proposed tactile guidelines state under the heading histograms, that "no space must be left between adjacent bars, as the data are continuous".
The use of spur wheels is in no way discouraged.
Hope this clarifies this misinformation about tactile guidelines!!Betty Marshall
