Thank you for the question!
The preferred location for tactile graphics is at the left margin.
Only if there is sufficient space on the line to include the full width of the tactile graphic following an identifier is this an option. This option saves some vertical space on the page.
If there is insufficient space on a line to accommodate the exercise identifier and the diagram, the tactile graphic should be placed at the left margin and below the identifier.
We hope this helps!
Thank you for your questions!
Our experts on the NBA Tactile Graphics committee offer the following:
Near the beginning of GSTG Unit 6 (page 6-2), we find the following statements:
"When no technical notation is present on the tactile graphic (e.g., only unmodified numbers and/or letters as defined in the Nemeth Code), the tactile graphic should be prepared in UEB."
and
"In general, regardless of the braille code used, the numeric indicator should be omitted when depicting measuring tools, number lines, and multiple-quadrant Cartesian graphs."
These tell us that a ruler with unmodified numbers and/or letters (using the definition for 'technical notation' from the Nemeth Code) should use UEB and not Nemeth.
Additionally, in GSTG 6.5.1, we find the following: "All number lines transcribed in Nemeth within UEB contexts must be enclosed within Nemeth Code switch indicators even though numbers may not be modified."
This means that, yes, number lines are treated differently than rulers _unless_ modified numbers and/or letters (as defined in the Nemeth Code) are present.
Following GSTG 6.10, in addition to that, "Numeric indicators are not shown with numbers on actual braille rulers, protractors, and calipers regardless of whether
the measurement tools are transcribed in UEB or Nemeth Code."To your last question, respectfully, we are unable to provide detail as to why BANA made these decisions.
Please let us know if this provides a clear and actionable set of responses to your questions! 🙂
Thanks APHers, for your question!
From your friendly TG experts on the NBA Tactile Graphics committee, we have the following:
Yes, a ruler with only whole numbers should always be transcribed in UEB, even in a UEB-in-Nemeth-Context document.
And yes, retain use of numeric indicator for cylinders, beakers, and measuring cups. In our reading, this is consistent with the chart on page 6-3 of GSTG.
GSTG 6.5.1 indicates that "All number lines transcribed in Nemeth within UEB contexts must be enclosed within Nemeth Code switch indicators even though numbers may not be modified. This applies whether they are drawn or created using braille symbols."
Number lines are covered in GSTG under 6.5. However, rulers are covered under Measurement tools in 6.10. Because it is not specifically addressed which code must be used for Rulers (unlike in number lines) use the following basic guidelines.
UNIT 6, p 6-2: When no technical notation is present on the tactile graphic
(e.g., only unmodified numbers and/or letters as defined in the Nemeth Code), the tactile graphic should be prepared in UEB.UNIT 6, §6.5.1, 3rd paragraph: All number lines transcribed in Nemeth within UEB contexts must be enclosed within Nemeth Code switch indicators even though numbers may not be modified. This applies whether they are drawn or created using braille symbols.
Let us know if this provides a clear and actionable response to your questions. 🙂
Hi Melody!
You ask two very good questions.
Your first question asks about preferences of tactile readers. One of the members of our Tactile Graphics committee is a very highly experienced tactile reader. This is what they have to say:
As a braille reader, my preference may vary regarding production method, depending on the type of diagram being reproduced. My first preference is graphics produced on a braille embosser, but enhanced with added collage elements, such as raised dots and added lines. I do think that microcapsule paper is good for preparing maps and some science diagrams.
Your second question asks about software and embossers for tactiles. We would like to refer you to the "Computer Aided Transcription" Ask an Expert forum with this question. They will have much broader experience across both braille production and tactiles production than we can offer here.
Hope this helps!
Thank you Kyle,
The baseline of each graph is treated like a number line. Following the table "Use and Omission of Numeric Indicator" on page 6-3 of GSTG 2022, we see that no numeric symbols are to be used on number lines so your assessment is correct.
The only part we see that will require the numeric indicator is the label for part (b) Height = 1/3.
We hope this helps!
Thanks for the question Marty!
Assuming that the back side of a TG (even page) is the last page of the volume, one would not apply either a print or braille page number. This assumes that “The End” will fit on the page with the tactile.
In the case where we are not at the end of a volume agencies may treat it somewhat differently. For example, if a graphic is on a100, the back shows b100, and the next odd page would be c100.
Grounding for these in GSTG and BF follows:
Since this question pertains to the page numbering of tactile graphics pages, we refer to GSTG Unit 5, Section 5.12.1 for interpoint braille, where on pages 5-24 and 5-25 the images show the preferred method of page numbering.
However, as you might acknowledge there not simply one answer that applies to all situations.
In particular, if the TG has a key page it would normally be bound facing a graphic, which may result in the need for an extra blank page. In addition, if there are multiple key pages, GSTG §5.12.4 shows images to indicate the page numbering for a single-sided volume (see page 5-27). See also page 5-30 for complex diagrams with multiple parts and key pages.
We also want to point out that in Braille Formats: Principles of Print-to-Braille, Appendix E.1.1 states that these are recommendations only, with the intent of providing a consistent approach. This allows agencies to set their own standards. (And our experts acknowledge that agencies do differ in their approach.)
All of that comes together to indicate that we should follow guidance in GSTG and BF if at all possible. If agencies decide to deviate from this, it should be done with consistency.
Hi Martin!
Now that we have GSTG 2022, we will shift our focus on answering your question to that new version. You can find GSTG 2022 on BANA's website at the following link.
In GSTG 2022, the applicable guideline to answer your question is 5.3.3.
- When a tactile graphic extends beyond one braille page, do not repeat the title on subsequent pages. In some instances, when there are multi-page keys following a graphic, it is acceptable to add descriptive text to “Key:” (e.g., “Key to Political Map:”).
- EXCEPTION: Headings on multi-page orientation and mobility maps should be repeated on all pages. (See Example 3-5: Prince Andrew High Main Floor.)
The EXCEPTION noted in 5.3.3 is elaborated upon in GSTG 2022 8.5.1. Note that this exception ONLY applies to multi-page orientation and mobility maps: "A map that includes large print visual features along with braille labels and tactile symbols may serve the needs of the low-vision traveler as well as sighted helpers who may be asked for assistance. Headings on multi-page orientation and mobility maps should be repeated on all pages, unlike headings on tactile graphics for textbooks."
Importantly, two examples provided in GSTG 2022 (i.e., Example 3-5: Prince Andrew High Main Floor and Example 7-4 Bus Routes) are examples of an O&M map. While that is indicated on the points pages that apply to those examples, if we miss that we might wonder why GSTG provides contradictory examples. In fact, there is no contradiction, it's just that these two examples illustrate the exception.
GSTG 2022 5.3.3 was instituted following a change in Braille Formats 4.3.10, which states, "Centered, cell-5, and cell-7 headings are not repeated when the text that applies to them is continued on the following page."
Hope this helps!
Michael,
Your question presented NBA's experts in tactile graphics with quite a challenge!
In GSTG 2022, section 5.2 provides us with an order in which information is to be presented to readers. The order of information is:
Heading, Caption, T-note, Key, Graphic, Source.So, from 5.2 we are told that source information is to be placed after the TG itself.
Next, because you are addressing TGs within a braille volume and not in a supplement, for more information about how to format the source citation, we look to Braille Formats for guidance.
BF section 9.5 addresses "Source Citations and Permission to Copy."Â 9.5.1b is the important part for your issue!
9.5.1b: "Location of the source citation is in the fifth cell to the right of the beginning of the previous line. At least one line of the source citation must be on the same page as the material to which it applies."
There is no guideline indicating that a blank line should be placed before the source material, but we conclude that this would be advisable if it can be made to work with BF 9.5.1.
In other words,
- add a blank line before the source citation for a TG if you can ensure at least one line of the citation will occur on the same page as the TG to which it applies.
- If you can't keep at least one line of the citation on the same page as the TG, then omit the blank line.
As above, keep margins for the source citation five cells to the right of the beginning of the previous line.
Overall, our TG experts indicate that consistency in application is of primary importance. The blank line between a TG and source citation is advisable but not required. Whatever you do, keep consistent so that readers experience consistency throughout your transcription.
We hope this answers all of your questions!
Hi Hollie!You ask a very good question! Pie charts (circle graphs) and fraction models share distinct similarities.
However, as your question implies, the purposes of pie charts and fraction models are different enough to warrant different treatments. Fraction models are used to help a pupil learn the concept of fractions. Pie charts communicate percentage quantities of different categories in some set.
Our experts point to these differences when advising how we should prepare tactile graphics for each type.
Fraction models use shading inside one fractional element in a shape to highlight the fraction that is being communicated. Your examples display this with color, and a tactile graphic would use texture. We are attaching a set of fraction models that display how the texture would be applied inside a fraction model. Note how the texture stops short of the circumference and the interior spoke lines. This is to ensure that those lines are clear and distinct for the reader.
Pie charts communicate the percentage of different categories in a set. The number and percent sign are critical parts of the pie chart. As described in GSTG 6.3, those numbers and symbols go <u>outside</u> the circle. 6.3.8 indicates that it is "not necessary" to show shading in a pie chart.Significantly, our experts advise that one should seriously consider <u>not including shading</u> so we don't obscure the interior spoke lines between segments. Additionally, textures and a key to the textures adds another bunch of details the reader has to work with. If we leave the lines clear and distinct and do not include textures, the reader has direct access to the graphic <u>and</u> numeric information in the pie chart.
We know that we didn't answer your question about BANA's intent, but we think our response gets to the issues that you are asking about. Please let us know if this helps you complete the project.
Hi Ronnie!
You don't mention if your TG is using Nemeth or UEB. If you're using Nemeth, then no contractions are allowed.
If you're using UEB we find that 5.8.1.4 stipulates the use of single-cell contractions. c(ong) uses a two-cell contraction for (ong).
However (!) 5.8.1.1 says <u>any</u> combinations of letters or letters and braille contractions can be used. It also says that the first letter of the key should be the first letter or contraction of the item. Using c(ong) satisfies these stipulations, so it is <u>permissible</u>.
That said, we will suggest that unless those cells are a really good representation of the word being keyed (the first 3 braille cells of the word itself), we would shy away from using c(ong).
Hi Shawn!
According to BANA Guidelines for the Transcription of Early Educational Materials from Print to Braille (3.1.1 and 3.1.2), transcriber’s notes can be used for all grades and can be used to list keys.
We recommend use of a key to show something like the following:
<p style="font-weight: 400;">A 2-inch square with the key explanation "bundle of 10 sticks" and a 3/8" by 2-inch vertical rectangle with the key explanation "1 stick". For younger grades these shapes should be solid/filled-in rather than outlines alone.</p>
Refer also to Guidelines and Standards for Tactile Graphics 6.8.2 and 6.8.2.1, since counting blocks are similar to what is used in your print example. 6.8.2 explains that they are often shown as "bundles", which yours are. 6.8.2.1 explains the amount of space to leave between each block (or in your case, between each bundle and individual stick).Each of the two "collections" in your example 6.a. should begin on a new line. Based on the sizes suggested above, we suggest that each of them would appear on a page of its own.
We would like to amend our earlier response to your question. The following adds more specific details from GSTG that will apply as you and your team make a decision on how to proceed in this case.
To start, regarding the use of switch indicators, while it is preferable to not switch multiple times it is not wrong if it becomes necessary due to the content of the key itself.
In Unit 5 of Guidelines and Standards for Tactile Graphics (GSTG), the rules for use of a key are included under 5.8.1 Keying Techniques for Transcribing Literary Material, and 5.8.2 Keying Techniques when Transcribing Using the Nemeth Braille Code for Mathematics and Science Notation, 2022 (and current updates).
In the Word document attached to the original question that was posted, a single letter followed by a period is used for the key entries. This use can be supported by Guidelines and Standards for Tactile Graphics 5.8.1.3 as follows:
<p style="padding-left: 40px;">
Single-letter keys are not recommended, but if used, they must be followed by a period. Do not use the grade 1 symbol indicator before a two-cell alphabetic key, even when the letter combination corresponds to a braille shortform.</p>In order to comply with both the Nemeth and the Tactile Graphics guidelines, the key itself should be prepared according to those rules. Only after the preparation of the key, do we address the decision on how to best handle the Nemeth switch indicators.
If the entire key is to be contained within one set of switch indicators, then the key should be prepared with either a 2 or 3-cell alphabetic key, or a numeric key.
If keys include a single-letter key followed by a period, the transcriber would have to use multiple switch indicators to surround the Nemeth description of the key symbols. This option requires more code switching for the reader.
The use of a single letter preceded by an English letter indicator would not comply with the rules of either code.
We hope this is sufficient to guide your team toward a good solution in this case!
