Taylor,
After reviewing the examples, our experts note that all of the graphic objects shown in the examples provided are 3-D shapes. This quality should be retained and they should be rendered as TGs to match what is in print. For question 9, we recommend not to include the auxiliary front view and to remove the tactile shading.
We also note that if the front view were to be included, it should be drawn as if the viewer were seeing it encountering it straight on. That is, it would not be angled.
GSTG guidelines to support this advice:
- 2.8 A print graphic may be simplified as long as the original intent is not compromised.
- 2.10 If the concept of depth is not required, a 3-dimensional view should be changed to a 2-dimensional view.
- 6.11.2.6 Shading should be used sparingly and only if required for the understanding of the concept.
With respect to GSTG 2.10, our experts note that based on additional pages of the textbook provided here, the concept of volume is being taught. With this, the 3-dimensional view should be kept.
Finally, we want to note that this advice applies to the specific images you have asked about. We cannot say that this advice should apply to all images in the textbook.
We hope this answers all of your questions! Please let us know.
That helps Taylor!
If it's not an imposition, is it possible that you could post the textbook pages that relate to this drawing and the activity of which it is a part? That would provide our experts with a bit more information to formulate a response to your question.
Taylor, thank you for the question!
When it comes to 3D objects, BANA guidelines should be applied depending on the intended use for a drawing. Can you provide us with details on how the tactile graphic will be used by a student in class activities?
Laurie and Lindy,
Thank you for the questions! Number Lines and Cartesian Coordinates are critical components of any STEM content and we wanted to make sure we had all the details covered. There are many intersecting rules and guidelines to consider and we hope the following addresses all of your needs. Please also see the attached document for an example.
- A raised line drawing would be preferable if the readers' familiarity with braille graphics is unknown and required if the readers are K-3.
- Alignment of numbers is with the first row of the digit rather than numeric symbol (GSTG 6.5.1.8).
- Yes, the tics should be extended 1/4" (6mm) above and below the line itself if using a raised line drawing (GSTG, section 6.5.1.12).
- Yes, put relevant symbols on SPECIAL SYMBOLS page per "Guidance for Transcription Using the Nemeth Code within UEB Contexts" item #17.
- However, following GSTG 6.5.1.13 (second bullet) If number lines appear infrequently, the braille number line symbols should be inserted as a transcriber’s note. So, if this is the only place that a number line occurs, place the symbols in a TN immediately preceding the graphic.
Let us know if this answers all of your questions!

Taylor,
Thanks for the vote of confidence!
In the interim before BANA completes its work on a new tactile graphics supplement, we are very happy to help with questions related to TGs of any sort!
Thank you Julie for the question!The Supplement is very useful! It demonstrates TGs in several common media, including Tiger embossed, microcapsule, and collage masters that are thermoformed. The purpose of the TG Supplement is to show the application of the rules and how those rules can be expressed differently using several common production methods.The Supplement has been recently updated to include examples showing TGs with both <i>UEB Technical</i> and <i>Nemeth in a UEB Context</i>. This revised Supplement must go through the BANA (Braille Authority of North America) Review Process and then to the BANA Board for final approval. When that is accomplished, a designated production agency will make copies and it will be distributed through established channels.At present, we have no timeline that forecasts when the revised and updated Supplement will become available. However, announcements of availability will be widely distributed when the time comes.Hi Taylor!
BANA provides a webform through which you can post questions or comments to the BANA Tactile Graphics Committee. You can visit that form at the following URL.

If you have other comments or questions, please don't hesitate to post them here.
Hi Julie!
After analyzing the materials you provided to us, we turned to BANA's "Guidance for Transcription Using the Nemeth Code within UEB Contexts" (June 2016) <http://brailleauthority.org/ueb/nemeth-guidance/Nemeth%20Guidance%20Final.pdf>.
Referencing the section of that document titled "Basic Guidance on Which to Switch," we find no mathematical expressions, fragments of such expressions, or signs of operation or comparison associated with maths in the graphic, so there is no need to switch into Nemeth braille in the graphic.
If you have other questions about the materials being transcribed please let us know!
Best wishes for a brilliant and bountiful Saturday!
Hi Julie!
That is a great question, and we think we've got the right response for you!
The NBA offers training for school districts, state agencies, braille production centers, prison braille programs etc. Please contact the NBA National Office for options to coordinate all aspects of the event with the requesting agency and the instructor.
If you are interested in learning more about how NBA's Training Bureau can work for you, please go to https://www.nationalbraille.org/training-bureau. You can fill out the form online and provide the Training Bureau with information regarding the needs for your organization.
Cheri, thanks for your question!
The attached graphic was sketched by one of our TG experts. The pie chart is approximately 5" in diameter and as shown will fit easily on an 11.5" x 11" page. As shown, this includes all of the numbers reflected on the print graphic, and full labels for some items from the print graphic. Long labels were reduced to 3-cell abbreviations that should be included on the braille key.
When creating the key, follow GSTG 6.3.7.2 with the order of items in the key the same as the order in which the sections appear on the graph in clockwise order, starting at the top (at the 12:00 position).
Notice that not all labels have leader lines. These should be used only where things get crowded. Otherwise, we may make the graphic harder to interpret.
The center of the graph is crowded, so it will be necessary to implement GSTG 6.3.4 and not draw all of the division lines all the way to the center. This is reflected in the attached graphic.
Following wording in GSTG 6.3.6, we want the interior of the graph to be unobstructed (no textures). It is advisable to never use textures in the center of a pie chart, for the same reason as you would move labels outside if print showed them inside the circle. This ensures better readability of the whole.
Let us know if this addresses all of your questions!
