3 Project Overview Personal Web background World Wide Web as a universal communication medium Current research and development is broad but not integrated Goal: fuse accessibility, standards compliance, and creativity 2

4 Root of Web Inaccessibility Shift from content to visual presentation Browser wars and proprietary HTML Design tools perpetuate visual emphasis and bad code Cost of revamping outdated websites Result: people with disabilities have been overlooked 3

5 Legal Environment Section 508 + 1998 Amendment –All Federal agencies must provide accessible means for using any of its information media and electronic equipment to all employees and members of the public. 4

6 Legal Environment Americans with Disabilities Act, Title III –Services provided by commercial or non- profit entities and state/local governments must not discriminate against or otherwise exclude users with disabilities Traditionally has applied to physical structures and hiring practices 4

7 Legal Environment Hooks v. OKBridge, Inc. –Extended ADA Title III to businesses that offer services via non-physical channels such as the Internet Other cases reaffirm that business Web services must be accessible –NFB v. AOL, Inc. –Maguire v. Sydney Olympics –Access Now v. American Airlines, Inc. 4

8 Diagnostic Testing Forty test subjects The diagnostic tests: –HTML standards –Web Content Accessibility Guidelines –Content load factor –Screen reader behavior 5

9 Diagnostic Testing HTML Validation Results (errors/line of code) –Popular sites: 1.37 –UNC-CH: 0.85 –Search Engines: 8.80 –Government: 0.86 –Accessibility Advocates: 0.18 5

10 Diagnostic Testing WCAG Results (% lines of code with errors) –Popular sites: 31.60 –UNC-CH: 20.73 –Search Engines: 71.56 –Government: 36.99 –Accessibility Advocates: 6.51 5

11 Diagnostic Testing Content load factor (Code-to- content ratio) –Popular sites: 11.28 –UNC-CH: 10.38 –Search Engines: 7.49 –Government: 8.63 –Accessibility Advocates: 3.15 5

12 The Premise Engineering a web resource to be universal – not just "accessible" in a standards-compliance sense – leads to better overall design for everyone, regardless of visual, mental, or other differences. 6

13 The Premise "Universal design" simply requires a paradigm shift: instead of coding a site to look good on a screen and then throwing in the latest validation hacks, the designer from the beginning conceptualizes a site that is not only usable but user-friendly in all scenarios. 6
