Page 6 Challenge: The Need 30 million Americans with print disabilities 15-20% in U.S. have language-based disability 285 million people with vision impairment worldwide
7
Page 7 Challenge: Everyone’s a Content Creator 300 million Potential authors & publishers in the US $1.76 billion in new edtech financing in 2013 2,500% more expensive to retrofit for accessibility from print (or print equivalents)

Page 11 Sample Image: Heart & Lungs ● Image description: provides basic accessibility to an image ● Tactile Graphic (2D): provides more information about spatial and physical relationships

Page 13 Image Description Hurdles Lack subject-matter expertise Not familiar with image accessibility (subjective) Variable levels of expertise across describers Expertise Time to find references Time to get trained up on best practices Time & cost required to produce content Cost-benefit: limited user reach when produced adhoc Time & Cost Guidelines for a broad range of image types Expert-generated descriptions (examples) User-centric resources (hard to understand) Lack of Training Content

Page 15 When Words Are Not Enough ● Tactile graphics are tactile representations of graphics –Not exact copies; strip out extraneous details and focus on what is required to understand content –Needed a brief verbal description is insufficient ● Often needed for… –Charts –Diagrams and schematics –Maps ● Subjects most likely –STEM –Geography
