  1. “Understanding the Standards” Accessible Instructional Material and Technology Workshop Accessibility Summit September 17-18, 2014 Nashville, TN

  2. Today’s speaker: Timothy Creagan Senior Accessibility Specialist U.S. Access Board

  3. Today’s topics: • Introduction: Policies, Standards & Guidelines • Barriers • Accessibility Standards • Section 508 • WCAG 2.0 • eBooks: • EPUB • NIMAS • iBooks • The “Refresh” of Sections 508 & 255

  4. Introduction: Policy, Standards & Timelines – from the Planning Template: • Adopt the general accessibility policy statement at system institutions • Identify a functional standard for access (substantially equivalent ease of use in the same place and at the same time as other students) • Identify a technical standard for access (W3C Accessibility Guidelines are a good benchmark)

  5. Why is Accessibility Important? • Barriers to use of ICT • How to over come barriers • Use of standards to improve access

  6. II. Barriers to People with Disabilities

  7. Have you ever struggled to seethe characters on a screen?

  8. Seeing: • Phones • Illuminated displays • High contrast controls • Large buttons • Computers • Zoom display • High contrast display • Screen reader

  9. III. Background: Accessibility Standards

  10. Accessibility Standards • §508 of the Rehabilitation Act • WCAG 2.0 SC Level A & AA - web/online content • WCAG 2.0 as applied to Non-Web Information and Communications Technologies (WCAG2ICT) - accessible technology (other than websites) C. Accessibility for E-Books: • EPub3 • NIMAS • iBooks • Miscellaneous: • Accessible E-Text • Open PDF

  11. A. Section 508 of the Rehabilitation Act Overview

  12. §508 General Requirements: Each Federal department and agency, as well as the U.S. Postal Service, when procuring, maintaining, developing or using electronic and information technology, must ensure that: • Federal employees with disabilities, and members of the public with disabilities seeking information or services, have access to and use of information and data that is comparable to the access and use by persons who are not individuals with disabilities, unless… Standard: ….an “Undue Burden” would be imposed on the agency.

  13. What Technology is Covered by §508? Includes, but is not limited to… Printers Telecommunications Computers Kiosks Software Office Equipment Websites

  14. However, time has passed… ….and Technology has changed. Today, what a product DOES is more important that what a product is CALLED. • “Feature”/“Function” versus “Product name” Question: How Can we use Section 508 to evaluate today’s technology?

  15. For example, what features are included in §1194.23 Telecommunications products ? • 2 way voice communication • Controls and keys • Hardware • Minimize Hearing aid interference • Text messaging(TTYs) • IVR (Interactive Voice Response, menus)

  16. Today there are many more products available with many more features : FOR EXAMPLE, “Telecommunications Products”: • “Landline” phones, wireless phones, Smart phones: Voice communication • TTYs, SMS, Blackberry, iPhone, Sidekick, Twitter: Text messaging • SKYPE: Calls/ Video Conferencing • Zoomtext or other software: Adjust size of text • Web sites: Contain information about product features

  17. Section 508 still applies; analyze the features of the technology: • Subpart B Technical Standards - do any apply? • E.g. §§1194.23, 1194.21, 1194.22 • Subpart C Functional Performance Criteria – do any apply? • E.g. §1194.31(a) – (f) • §1194.5 Equivalent Facilitation - the new technology or design [not necessarily in Section 508] results in substantially equivalent or greater access to and use of a product for people with disabilities – DOES THAT APPLY? • E.g. voiceover for Apple iOS • §1194.3 General Exceptions: Do any apply? • E.g. §1194.3 (e ) Fundamental Alteration

  18. What about Technology that has features not addressed by §508? EXAMPLE: • Mobile Telecommunications • iPods and Podcasting - Operate without buttons • Smart Phones with touch screens • [Voiceover] • [Talkback]

  19. Making technology accessible: • Captions • Alternative formats: text for audio, alt tags for images • Use of API (Application Programming Interface) to address compatibility between AT and IT software (make products interoperate) • “Apps” or “Applications” on Smart phones

  20. §1194.5 Equivalent Facilitation “Nothing in this part is intended to prevent the use of designs or technologies as alternatives to those prescribed in this part provided they result in substantially equivalent or greater access to and use of a product for people with disabilities.” 20

  21. Using Equivalent Facilitation to achieve access by alternative means: • Use WCAG 2.0 (Web Content Accessibility Guidelines) • What is WCAG 2.0? • International standard for web documents and web applications • W3C Standard (2008) • ISO Standard (2012): ISO/IEC JTC-1 40500:2012 • W3C/WAI: World Wide Web Consortium / Web Accessibility Initiative • Developed through open and inclusive standards process

  22. B. WCAG 2.0 Overview

  23. Why Use WCAG 2.0? • Technology Neutral • Unlike 508 1194.22, not HTML specific • Success Criteria: (aka “Requirements”) • Address existing 508 technical criteria (1194.21 and .22) • Address 508 functional performance criteria • Hearing, Sight, Manual Dexterity, Speech • Partially address Cognition, Language, and Learning (CLL) • Are Objectively Testable • Written to be evaluated as yes/no or true/false statements • Designed so as to not require significant subjective expert judgment to evaluate. 23

  24. Is WCAG 2.0 being used now? FEDERAL AGENCIES: • Department of Transportation, Non-Discrimination on the Basis of Disability in Air Travel: Accessibility of Web Sites and Automated Kiosks at U.S. Airports, Final rule December 13, 2013 • Department of Justice, Accessibility of Web Information and Services of State and Local Government Entities and Public Accommodations, ANPRM July 2010 (Proposed) INTERNATIONALLY: • Canada • Australia • New Zealand • European Union (EU) (Mandate 376) 24

  25. POUR’s Overlapping Tenets WCAG 2.0: POUR Concept The 4 Principles • PerceivableContent is made available to the senses - sight, hearing, and/or touch • OperableInterface forms, controls, and navigation are operable • UnderstandableContent and interfaces are understandable • RobustContent can be used reliably by a wide variety of user agents, including assistive technologies Illustration of the words Perceivable, Operable, Understandable and Robust wrapping over and under each other. 25

  26. How the WCAG 2.0 docs relate… Diagram of How the WCAG 2 documents are related. The W3C Standard, “WCAG 2.0” is (in the center of pyramid), with link to Customizable Quick Reference “How to Meet WCAG 2.0” (at top of pyramid) and link to Detailed Reference “Understanding WCAG 2.0” (at right side vertex). The Instructions for Developers “Techniques for WCAG 2.0” (at left side vertex) are linked from the Understanding and How to Meet documents. Three to five bullet points summarize each document. 26

  27. WCAG 2.0: 38 Success Criteria (Level A & Level AA) Perceivable • 14 Level A and AA Success Criteria in TOTAL • 9 at Level A • 5 at Level AA Operable • 12 Level A and AA Success Criteria in TOTAL. • 9 at Level A • 3 at Level AA Understandable • 10 Level A and AA Success Criteria in TOTAL. • 5 at Level A • 5 at Level AA Robust • 2 Level A in TOTAL. • 2 at Level A 27

  28. “How to Meet WCAG 2.0” “How To Meet WCAG2.0” - daily resource document for the day-to-day Developer • is a Database • Quick Reference: • http://www.w3.org/WAI/WCAG20/quickref/ • Customizable • Searchable • A way to get to the Techniques and Failures 28

  29. Concluding thoughts about WCAG 2.0 : • The Success Criteria are the Requirements • The Techniques are notrequired but provide guidance • WCAG 2.0 can be used – Equivalent Facilitation (§1194.5) • Built-in Prioritization Path/Plan (for Development/Remediation/QA) • WCAG 2.0 Support Documents are Regularly Updated 29

  30. W3C Resources: • Web Content Accessibility Guidelines (WCAG) 2.0: URL: http://www.w3.org/TR/WCAG20/ • Understanding WCAG 2.0:Stable URL: http://www.w3.org/TR/UNDERSTANDING-WCAG20/ • How to Meet WCAG 2.0: URL: http://www.w3.org/WAI/WCAG20/quickref/ • Techniques for WCAG 2.0: Stable URL: http://www.w3.org/TR/WCAG20-TECHS/ • Formal adoption in Canada, Australia, New Zealand URL: http://www.w3.org/WAI/Policy/ 30

  31. “Guidance on Applying WCAG 2.0 to Non-Web Information and Communications Technologies (WCAG2ICT)” • URL: http://www.w3.org/tr/wcag2ict/ • describes how the Web Content Accessibility Guidelines (WCAG) 2.0 [WCAG20] and its principles, guidelines, and success criteria can be applied to non-web Information and Communications Technologies (ICT), specifically to non-web documents and software. It provides informative guidance (guidance that is not normative and does not set requirements). • This document is a Working Group Note, and is part of a series of technical and educational documents published by the W3C Web Accessibility Initiative (WAI) and available from the WCAG 2.0 Overview.

  32. How does each of 38 WCAG 2.0 Level A & AA Success Criteria(SC) apply in the context of non-web ICT, if it were applied to non-web ICT? RESULT: Task Force found that the majority of success criteria from WCAG 2.0 can apply to non-web documents and software with no or only minimal changes. • 26 SC apply directly as written and as described in the “Intent” sections from the updated Understanding WCAG 2.0 [UNDERSTANDING-WCAG20]. Thirteen of these twenty-six applied without any additional notes. The other thirteen applied as written but additional notes were also provided for assistance in applying them to either or both non-web documents and software. 38=26 + 12 • Remaining 12 success criteria: • 8 apply as written if certain Web-specific terms or phrases like “web page(s)” are replaced with non-web terms or phrases like “non-web document(s) and software”. • Remaining 4 SC: apply in situations when “a set of web pages”, or “multiple web pages” share some characteristic or behavior.

  33. C. Accessibility for E-Books Overview

  34. What is an E-book? • “electronic book” or e-book, digital book, or e-edition) - a book-length publication in digital form, consisting of text, images, or both, readable on computers or other electronic devices. • Content may have a printed version or not • E-books are intended to be read on e-book readers (e.g. Kindle or Nook) but can be read on computers, tablets or smartphones. • E-book reading is increasing in the US: by 2014 28% of adults had read an e-book, compared to 23% in 2013.

  35. Making eBooks Accessible • Mature approaches • EPUB • Nimas • iBook • Developing • eText • Open PDF • Currently in use for a wide variety of content • Used in academic setting or still in development

  36. What is EPUB? • EPUB - format for digital books (eBooks), • Widely adopted • Specifications significantly increase the format's capabilities • Supports a wider range of publication requirements, including complex layouts, rich media and interactivity, and global typography features. • Expectation: EPUB 3 will be utilized for a broad range of content, including: • books, magazines and educational, professional and scientific publications.

  37. EPUB standard: • A distribution and interchange format standard for digital publications and documents. • EPUB defines a means of representing, packaging and encoding structured and semantically enhanced Web content — including HTML5, CSS, SVG, images, and other resources — for distribution in a single-file format. • EPUB 3, the third major release of the standard, consists of a set of four specifications, each defining an important component of an overall EPUB Publication. • For more information, see: http://www.idpf.org/epub/30/spec/epub30-overview.html

  38. What is the National Instructional Materials Accessibility Standard(NIMAS)? • A technical standard used by publishers to produce source files (in XML) that may be used to create multiple specialized formats for students with print disabilities. • Examples of the formats are: • Braille, large print, HTML, DAISY talking books using human voice or text-to-speech, audio files derived from text-to-speech transformations • For more information, see: http://aim.cast.org/learn/policy/federal/what_is_nimas#.VBDEZ9ju3xM From the National Center on Accessible Instructional Materials, U.S. Department of Education

  39. What is iBook? • iBooks is an e-book application by Apple Inc. for its iOS and OS X operating systems and devices. • released for the iPhone and iPod Touch in mid-2010, as part of the iOS 4 update • Install free from the Apple store • supports e-book formats EPUB and PDF • Features: adjust contrast, font size, text, brightness, individual word search

  40. Miscellaneous E-Book standards Overview

  41. eText – an accessible, electronic course content delivery platform from the University of Illinois: • eText delivers textbooks and other classroom materials with multimedia, notes, and assignments embedded directly in context. Plain text format. • Instructors can add original or existing materials easily, and students can save 40-75% versus traditional books • See: https://etext.illinois.edu/
