  3. Tactile Diagrams Also referred to as Tactile Graphics Raised line drawings Found in Braille Textbooks Braille Supplements and Stand-alones

  4. Production Methods Collage and/or tooling - Thermoform copy Microcapsule paper (Swell paper) Computer designed and embossed Commercial production (press braille; resin, ink or powder deposit)

  5. Decision Tree for Tactile Graphics • Is the information a repeat of facts in text? • Would the information be more meaningful in text form? • Does the graphic require the reader to use visual discrimination or visual perception? • If yes, do not produce a tactile graphic.

  6. Would be more meaningful in text form

  7. Decision Tree for Tactile Graphics • Is the actual object unavailable to examine by touch? • Does the reader need the information to participate in an activity, complete an assignment, understand the concept? • If yes, produce a graphic

  8. Decision Tree for Tactile Graphics • From BANA Guidelines and Standards for Tactile Graphics 2010 Braille Authority of North America

  9. How to Write Descriptions The description author should consider three basic questions about each image in order to give effective and efficient description. • Why is the image there? • Who is the intended audience? • If there is no description what will the viewer miss?

  10. Determine What To Describe Before describing an image, the description author must determine what on the page is already accessible and what is not accessible. • What is text? • Is the text accessible? • Is the text navigable? • What is an image?

  11. What To Describe Activity Sidebar Main Text Image

  12. Title info What To Describe Text or Image of Text? Image Text or Image of Text?

  13. Recommendation is for a Tactile Diagram. Resulting Alt Text: A diagram shows the circulation of oxygen rich and oxygen poor blood through the heart and lungs.

  14. STEM Description Guidelines Four years of NSF-funded research produced guidelines for making STEM images accessible. STEM = Science, Technology, Engineering and Math

  17. PROSE Recorded rate of violent crimes and property crimes: aggravated assault every 37 seconds, robbery every 1.2 minutes, forcible rape every 5.8 minutes, murder and nonnegligent manslaughter every 31.1 minutes, larceny-theft every 5 seconds, burglary every 15 seconds, motor vehicle theft every 29 seconds. 

  18. MARK UP • Recorded rate of violent crimes and property crimes: • aggravated assault every 37 seconds • robbery every 1.2 minutes • forcible rape every 5.8 minutes • murder and nonnegligent manslaughter every 31.1 minutes • larceny-theft every 5 seconds • burglary every 15 seconds • motor vehicle theft every 29 seconds

  19. PROSE Recorded Rate of Property Crimes A line chart shows the recorded rate of property crimes 1960 to 2007 including larceny theft, burglary and motor vehicle theft. All property crimes increased significantly from 1960 and peaked in the early 1980s. Property crimes fell then rose again over the next decade. Since the late 1980s to 2007, property crime has been on a steady decline, though still higher than in 1960. The following data are approximate, with the year followed by the crime rate. All Property Crimes: 1960 1,800, 1970 3,500, 1980 5,500, 1990 5,100, 2000 3,600, 2007 3,300. Larceny-theft: 1960 1,000, 1970 2,200, 1980 3,300, 1990 3,200, 2000 2,500, 2007 2,300. Burglary: 1960 600, 1970 1,100, 1980 1,600, 1990 1,300, 2000 700, 2007 700. Motor vehicle theft: 1960 100, 1970 500, 1980 600, 1990 650, 2000 400, 2007 300.

  20. MARK UP Recorded Rate of Property Crimes A line chart shows the recorded rate of property crimes 1960 to 2007 including larceny theft, burglary and motor vehicle theft. All property crimes increased significantly from 1960 and peaked in the early 1980s. Property crimes fell then rose again over the next decade. Since the late 1980s to 2007, property crime has been on a steady decline, though still higher than in 1960. The following data are approximate, with the year followed by the crime rate.

  22. Accessing image descriptions • Image descriptions can be included in a variety of digital publications… • DTB, e-books, PDF, HTML • …through a variety of methods • @alt, @longdesc, prodnote, describedby, visible text, hidden text

  23. Accessing image descriptions • Not all description-delivery methods work on all devices • Additional considerations • while markup might be permitted in the description (depending on the authoring tool), the reader may not interpret the markup correctly • plain text vs markup • text vs TTS vs audio

  24. Accessing image descriptions • Demonstration: • Read2go (http://read2go.org) • iOSDTB reader w/built-in TTS • PDF • read with Windows screen reader • HTML • read with any screen reader

  25. Accessing image descriptions • Different authoring applications permit different forms of image descriptions • DTB: Tobi, Dolphin Publisher, OpenOffice, Poet • e-book and PDF: InDesign, OpenOffice, Word • HTML

  26. Accessing image descriptions • DIAGRAM product matrices: image-description support across many hardware/software devices: http://diagramcenter.org
