3. Session CoversDefine tactile graphicsWhat to include in the tactile versionModes of production3D modelingResources
4. When More Is NeededSometimes even a long description will not really convey the information in the graphic.The alt text will not be sufficient for a student’s needs.Tactile graphics to the rescue!
5. What Are Tactile Graphics?A tactile graphic is a tactile representation of the content conveyed by a graphic.Tactile graphics are not simply “copies” but are new conceptualizations of the information being conveyed.They convey the same information in a totally different form.
6. Handling GraphicsWhen determining the purpose, always consider the context in which the graphic is being shown.The same graphic may have a different purpose in a different context.Sometimes decorationSometimes informational
7. How Do I Decide??Does the student need to do something with the graphic or understand something from it?InformationalIs the graphic simply entertaining or “pretty”?Decoration
8. Context and IntentWhat is the learning objective for this graphic?Why is it here? What is the concept? What do the authors want you to learn?What is it that you need to do with the information?Activity? How do you use the information?
9. Asking Prof and StudentCan ask Prof to establish priorityHowever don’t just ask what tactiles to create!Ascertain what the intent is of graphic and then use judgmentShow prof tactile image library and askAsk student his/her preferenceDoes student read braille? Have experience with tactiles?
10. Reality CheckNot all students are familiar with tactile graphics.To help students learn…Start with a 3D modelPresent the same concept with collageNow create a raised line representation of the concept
11. What Do You Include?May not need the entire graphicFocus on what the graphic is trying to convey and ignore the decorative elementsHow do you know what to include?Author’s IntentLearning ObjectiveDecision Tree
12. Making a DecisionHow are we going to convey the information represented in the graphic?BANA Guidelines BANA (www.brailleauthority.org) has a great decision tree for determining what you need for a tactile graphicTactile Graphics Manualwww.brailleauthority.org/tg/web-manual/index.html
13. Decision Tree for TactilesPurpose of the decision treeDecide if you need to create a graphicFigure out what you are going to include in the graphicFigure out your method for creating the graphic

16. Tactile GraphicsCreating Your Graphics
17. What Is a Tactile Graphic?Tactile representation of a two-dimensional graphic (drawing, chart, graph, etc.)Tactile interpretation of a graphicNot an exact copy—convey the same information in a totally different formYou have artistic license; you can change scale and orientation as necessary
18. Tactile RepresentationSimplifyThink about a young child’s coloring bookBasic outlines work wellReduce “noise”No shading, stippling, shadowsLimit use of “perspective”Do not include extraneous detailCheck text to see what information is discussedInclude *only* needed information
19. Graphic Vocabulary Distinctly different areas, fills, etc.—limit to 4 or 5 (each)Textures / fillsBlank is a texture; avoid solid blackLinesSmooth, dotted, thick, thinPointsDo not use stars! Circles or squares work wellCreate a test sheet in your preferred medium
20. Thinking Like an ArtistArtists do not complain that sculpting in wood is different from sculpting in stone!Artists learn the properties of their materials and then ask, “What can I create with this?”Focus on what the medium can do and then determine how to create end product
21. PropertiesArtists understand that they have to work within the constraints of their materialsOil paint, watercolor, oil pastels all behave differently and give different effectsWith tactilesPIAF, Tiger, Phoenix, Thermoform, etc. all have different capabilities
22. Remember…Art is in the “eye” or, in this case, finger of the beholderFocus on what it feels like and less on how “pretty” it looks
23. What to ConsiderBANA Tactile Graphics Guidelines BANA (www.brailleauthority.org) Rules for tactile graphicsAccessible Image Sample Bookhttp://diagramcenter.org/standards-and-practices/accessible-image-sample-book.htmlhttp://youtu.be/6iQy9avVNdU
24. Creating the GraphicsAlways pretest lines and texturesTextures reproduce differently on Tiger, PIAF, Thermoform, etc.Use heaviest lines/textures for most important elementsPlace distinctly different lines/textures near each other.
25. Rule of “Fingers”Fingers have to move to readMake shapes at least an index-finger width wideExcept for point markersAllow a little-finger width between labels and shapesNo extraneous linesLimit leader lines; label areas instead
26. Braille Labels on Swell PaperType labels in Duxbury Enter in print view and then translateCopy translated braille and paste into graphics programSelect labels and make them Braille font Fonts come with DuxburySet font size to about 28 point
27. Braille CodesOld braille code (EBAE) had separate codes for Math (Nemeth Code), Chemistry, Computer Braille (CBC)MusicForeign LanguageNew braille code, Unified English Braille (UEB), went into effect January 2016Ask students which code they use
28. Tactile TipsAlways include a title at the topWrite out in words what the graphicis forFigure out lines and fills before starting to drawDevelop basic axes, grids, etc. (templates) to reuseOne print graphic may be multiple tactile pages
29. Need a Key?Always place keys before the graphic!Use logical two-letter abbreviations, rather than numbersTests have shown abbreviations are easier to remember

46. Using the ComputerDesign graphic on computerIllustrator, Corel DrawPhotoshopWordPrint from laser printerMake copy on swell paper using copy machineAnd toast!
47. Pictures to OutlinesPicture Stencil Makerhttps://online.rapidresizer.com/photograph-to-pattern.phpSnaps Touchhttp://www.snapstouch.com/Also good for coloring books ;-)
48. Swell Paper AdvantagesCan create templatesGraph paperXY axesVenn diagramBasic mapsBasic outlines of biology conceptsAnything that you can reuse!Can print from a PDFTactile Graphic Image Libraries available

51. What about 3D?
52. Reality Check for 3DEasy to create “blobs”Best uses: science, math, mapsSome success with bas relief of artworkLots of questions on what is useful and what is notIf include braille labels, make sure braille is readable (28 point font)Also beware of fragility—braille can easily
53. Diagram CenterGood information on using 3D printersArticle on how to include braillehttp://diagramcenter.org/3d-printing.html
54. TechnicallyRequires a 3D printerPlease note: printers need to be used—sitting around is not good for themSome online libraries contain accessible materials, but it helps if you can drawSoftware makes it somewhat easier, but if you have no art background, you may struggle
55. 3D PrintersWide range of optionsBe aware of key characteristicsSize, filaments used, open or closed frame, ease of cleaning, cost
56. 3D Modeling/Printing SoftwareProprietary ApplicationsSome open source options availableBlenderCura / Ultimaker CuraTinkerCadAutoDesk appsOpenSCADAccessible CAD design
