Labeling and Placement of Computer Generated Tactile Graphics
Like all illustrations and graphic design, labeling has mainly to do with consistent font size,
typeface, and placement. It is no different with tactile graphics with the exception that labels
along with other graphic components included on a tactile graphic illustrations are subject to
rules recommended by the BANA Guidelines and Standards for Tactile Graphics, 2010.
Braille Font Typeface
Labels for computer generated tactile graphics are produced using braille typeface supplied by
the Tiger Software Suite, Duxbury Braille Translator, QuickTac, Microsoft Word, and Braille
2000. QuickTac, Tiger Design, and Firebird uses it own “bitmap” labeling system. This type of
labeling is available within their drawing layout as a typing tool, much like a typing tool within a
drawing or paint (bitmap) application.
Most of the computer generated tactile graphics (Tiger and Swell) are produced using a
Microsoft Office application (Word, PowerPoint and Excel). Braille font typefaces do not come
native to any of these applications. If Duxbury 11.1 (or any previous version) is installed a
couple of braille fonts are automatically installed. If Tiger Software Suite is installed more
“Tiger” braille font typefaces are installed.
If you do not have either of these applications, braille fonts can be manually downloaded and
installed. Braille font typefaces available for download and installation can be obtained from
these website locations:
 TSBVI: Download Braille and ASL Specialty Fonts
 Duxbury: Free Download of the Braille True Type Fonts
Be careful not to stray far from the true type braille font typeface family. There are many
“imposters” out there. Do not use: shadow, 3D, or decorative braille font typeface. Any fancy
ones, as cute as they can be, please ignore. It is not about "looking good", it is about readability,
literacy, and access.
Braille Font Size
Braille fonts cannot vary in size much at all if any. Tactile graphic illustrations should only take
two braille font sizes. Labels when translated by the Tiger Software Suite should be at least 29
point size. For encapsulated “swell” paper production, the size is around 24 point size.
Please note that the bitmap braille fonts offered in QuickTac, Tiger Designer, and Firebird all
uses their own font size. QuickTac font is slightly smaller than the Duxbury font even though a
QuickTac illustration is embedded in a Duxbury document.

Installation of a Braille Font
Windows 7 and Windows 8
(According to the Microsoft website “Installing fonts on Windows”)
Option 1
First be sure that you have administrative right on the installing computer.
Double-click on the font file that was downloaded to open the font preview.
Select “Install”
You can also right-click on a font file, and then select “Install”.
Option 2
On Windows 7
Select Control Panel from the Start menu*.
Select “Appearance and Personalization
Select “Fonts”
Drag a font file and drop it in the Fonts Control Panel.
Before dragging it in the font folder, make sure the file is not compressed.
*On Windows 8, you can get to the Font Control Panel by searching for “Fonts”.
Windows XP
(According to the Microsoft website “Installing fonts on Windows”)
From the “Start” menu select “Control Panel”
Select the “Appearance and Themes” category.
Select “Fonts” from the “See Also” panel at the left of this screen.
On the “File” menu, select “Install New Font”.
Click the drive and folder that contains the font(s) you want to add.

Label Placement
The placement of labels on a tactile graphic is very important to braille literacy and tactile
graphic interpretation. The main reason for the "strict" guidelines standards for tactile graphic,
including label placement, is for the user of tactile graphics to interpret the illustration with the
least amount of cognitive load as possible.
The gridlines in a Word document can be used to plan not only the graphic but also the labels.
The BANA Tactile Graphic Guidelines recommend that labels are placed between 1/8” to
¼” from the object it identifies. Knowing this, set the both the vertical and horizontal grid
setting configurations to .13” which is the default setting in the Draw Grid configuration window.
Figure 1: Illustration of the Grid setting section of the Draw Grid Configuration Window
This allows spacing in any direction to be in 1/8” increments. It takes some of the guess work
out and can make movement into position quicker by using the directional arrow and the control
keys instead of using the mouse.
With gridline on, placement of a label is confined to movement from gridline to gridline. Use the
arrow key to grossly place the label near the object location. Depending on the direction, the
label will “hop” from gridline to gridline. Once near the preferred location, fine tune placement by
using the arrow keys plus the control key to “release” it from the gridlines. Doing this command
will move the label (or any object) by one pixel increment in any directions.

Figure 3: Illustration showing Placement of a Label
If you need to see labels in print first before translating into braille, use the typeface Courier New
and font size either 24 or 29 point, depending on the production mode.
Production Standards for Computer-Generated Tactile Graphics:
 29 point font size for Tiger production
 24 point font size for swell paper production (PIAF/TIE)
 Courier New typically used when planning layout with regular alphabet letters
BANA Tactile Graphic Guidelines and Standards on Labeling
General Label Placement:
Labels are outside of pattern filled objects.
Labels are outside of enclosed objects.
Labels are placed horizontal on the tactile graphic.
Measurement line labels are placed beside the line.
Number Label Placement on a Graph, Clock, and Number Line:
On the horizontal axis, dots 456 of the first cell of the value should be lined up with
vertical grid line or tick mark and be spaced 1/8 inch from the tick mark or axis line.
On the vertical axis, dots 25 should be aligned with the grid line or tick mark on the
vertical line and be spaced 1/8 inch from the tick mark or axis line.
1/8" spacing between labels and object endpoint (tick marker, arrowhead, lead line)
¼" max spacing between labels and other objects
Labeling Properties:
Illustration containing many labels should consider a key.
Do not use various sizes braille on a tactile graphic.
Letter sign is not required with capitalized letters but is required for uncapitalized letters.
Labeling and Placement of Computer Generated Tactile Graphics
If text in a label is split between two braille lines, the runover line is left justified.
Numeric Indicators
Different tactile graphic illustrations require the numeric indicator while others do not. Here
below is a list of different graphics and whether they omit or need a numeric indicator.
Bar Graph
Cartesian Graph
Line Graph
Number Line
Pie Chart
Scatter Plots
Time Line
If it is necessary to omit the numeric indicator (and one is required) it may be omitted but
there needs to be an explanation in a transcriber's note prior to the graphic.
Typing Input Using the Tiger Software Suite
On a Word document, because braille labels in the layout window containing the graphic need
to be planned out and can be rather complex, and the glitches experienced with the Tiger
Software Suite during translation into braille, it is suggested to make the line drawing illustration
on one page and type out a list of labels on another document.
Using Inline Text and Floating Graphics
Reasons for Using Inline Text on a Tactile Graphic Production:
An inline title sets a left justified guide for the floating graphics.
It sets a tone for a left to right and top to bottom reading order.
It assists in creating a better organized document.
Labeling and Placement of Computer Generated Tactile Graphics
Title should always be inline text.
The Area of a Triangle
Formula for the area of a triangle:
b  h  A
Be sure to translate into braille
before pasting in the graphics.
b is the base of the triangle.
h is the height of the triangle.
Inline text does not need to
be included in the grouping.
Group all "floating"
objects together into one
Paste in inline text
document after all text is
translated into braille.
Figure 4: Illustration of the Components of a Tactile Graphic and Design Suggestions
Preparing the Graphic Document
Set the gridlines to vertical and horizontal spacing (.125" each)
Draw all the graphic and illustrations.
o Points
o Lines
o Shapes (set or freeform)
o Fill Patterns
Place all floating textboxes on the document.
Configure all textboxes to no fill and no outline.
Include all MathType formulas if included in a textbox.
Labeling and Placement of Computer Generated Tactile Graphics
Make sure to include all lead lines.
Make sure all pattern are included.
Check all braille for mistakes.
Group into one object.
Select "Apply Tiger Layout"
Ungroup if needed (depending upon labels "new" position).
Reposition "moved" labels accordingly.
Group into one object.
Translate the document into braille text labels.
Ungroup if needed. If not need, the illustration is ready.
Reposition if necessary (apparent with MathType formulas).
Group into one object.
Illustration is ready for transfer to the inline text document
The graphic document should only contain the illustration and the labels identifying parts of the
illustration. Make sure to group textboxes and the graphic together as one document.

Preparing the Inline Text Document:
Consider the amount of space available within the size of the page.
o Maximum width of a tactile graphic is 40 cells.
o Maximum length of a tactile graphic is 25 lines.
Open a new blank Word document.
Type all text that is needed for the document. Do not skip any lines.
Use this ordering sequence for the tactile graphic document (BANA Tactile Graphic
1. Heading (title)
2. Caption
3. Transcriber's Notes
4. Key
5. Graphic
6. Source

Keep the cursor at the end of the last line of text.
Make sure to enter MathType equations if it needs to be included in the inline text
Once accomplishing this, select the Tiger menu that is located in the "Add-Ins" tab on the
Ribbon, than select "Apply Tiger Layout".

Figure 9: Screenshot of Text in a Word Document. Text is enlarged to 29 point font size.
 Font size changed to 29 point (braille cell size).
 Blinking cursor is still located on the last line entry point.
 The MathType information stayed the same as the previous font size*
 A line space was manually entered, after conversion, between the title and the first line of
the content.
*The actual MathType information is considered a bitmap which explains why it did not change
in size because is default to 12 point size. You can change the default layout to match the text
font size after "Apply Tiger Layout" is activated (see below). The MathType text will change to
the same braille font size as other labels on the document.
To change the MathType default font size to match the text font here is the pathway:
MathType (tab)InlineSizeDefine( a Define Sizes dialog window is
opened)Fullchange the font size In the edit field.

All inline text kept their assigned positions.
Press the Enter key until the cursor is at position one on the last line of entry.
Notice the MathType equation is the same font size as the other braille entries.
Line runovers have to be manually entered.
Use the "Show Paragraph" markers to help with indention and spacing.
The inline text document is ready to receive the "floating graphic" illustration.

Title can still move to the center of the document if needed.
The illustration is left justified (lined with the first line of inline text).
The illustration is positioned to fit one blank space after the last line of inline text.
Notice where the cursor is located, more information can be added here if needed.
All inline information can be changed to meet runover rules.
Labeling and Placement of Computer Generated Tactile Graphics
Placement of Tactile Graphics According to the BANA Tactile Graphic Guidelines and
An illustration should be inserted as close as possible to corresponding discussion in the text. If
an appropriate location is not apparent, place it at the end of the print page in which it appears.
A blank lie is required before and after a tactile graphic.
When it is necessary to move an illustration from its position in the print text, insert a
transcriber's note at the original position, giving the print page number of the new location. A
second transcriber's note must be inserted before the illustration at its new location stating the
page number of its position in the print text.
When individually numbered or lettered diagrams are presented in print, they should be placed
below the other (vertically) rather than side by side (horizontally).
For test materials or answer choices where a comparison is being made between diagrams,
they may be placed side by side in order to keep them on the same page. Items would be
spatially arranged in order, horizontally, regardless of what is shown in print.
Please refer to the BANA Guidelines and Standards for Tactile Graphics for more in depth
information. Remember too that the guidelines are rules for textbook and standardized test
production. Worksheets and daily braille production for student in K-12 setting need formatting
standards similar as much as possible to the textbook and tests, however, details accordingly
can vary.
It is important that daily production requires getting braille and tactile graphics under the finger
of students that need them in a timely manner. This is not an endorsement, but rather a
consideration when developing tactile graphics. Remember this is about access and availability.
