Thank you for your patience while I searched for an answer to your question. I would like to thank Bonnie Read for her help and suggestions for the transcription of the graphic calculator images in your example (Example 3). She has given us two ideas. One method uses one transcriber-created symbol and two of the half-bracket symbols of the Nemeth Code. The other method uses transcriber-created symbols for all of the bracket shapes.

The five shaded screen examples will be illustrated below. Note that the blue shaded area before each "2" is a shaded (highlighted) answer box. Use the 456 highlight indicator as listed in Graphing Calculator Guidelines 5.3 on page 3.

I'm not sure I can mix the braille font in the text on this page. If it doesn't work, you can paste the ASCII characters into your braille document. I have also attached a braille file illustrating the examples.


--First answer box: There is no braille equivalent for the square "u" shape between the digits 2 and 7 in the first screen. Create a shape for this according to Nemeth Rule XVI Section 107. Bonnie chose to use the shape indicator followed by the letters su for "square u". (This symbol must be listed on the Special Symbols page. For example, $su Square u-shaped symbol (Nemeth Code symbol). You could use another transcriber created symbol if you choose as long as you list it on the Special Symbols page with the appropriate definition.

--Second answer box: There is no underscore symbol. I chose to use a general omission symbol (full cell) modified with a horizontal bar directly under, according to Nemeth Code Section 86.c. Instead, you could opt to make another transcriber created symbol.

--In answer boxes 2, 3, and 4 she uses the Half Brackets as listed in Nemeth Rule XVIII. It is not required to list these symbols on the Special Symbols page, but I might be tempted to since they are not often encountered.

--The last highlighted answer box is straightforward Nemeth, after the highlight indicator.

Here are the five answer boxes, using METHOD ONE.



A transcriber shape has been created for all four shapes, interpreting them as sides of a box. The following transcriber shape symbols could be used indicating sides of the box:
l – left; b – bottom; r – right; t - top.

The first shape is $lbr
The second shape is $b
The third shape is $br
The fourth shape is $lt

Here are the five answer boxes, using METHOD TWO.


I'd be curious to know what you end up doing!
