    The overlap between Web Accessibility and Web Usability for Older people The overlap between Web Accessibility and Web Usability for Older people Presentation Transcript

    • WEB ACCESSIBILITY and WEB USABILITY FOR OLDER PEOPLE School of Computing University of Dundee, Scotland David Sloan Universitat Pompeu Fabra, 29 de Octubre, 2009
    • Outline of my talk
      • Exploring the overlap between web accessibility and web usability for older people
      • Comparing:
        • best practice
        • standards, legislation
        • Awareness and attiudes
      • The challenges
    • Who am I?
      • Researcher and consultant at University of Dundee, Scotland
        • A centre of excellence in information technology for older and disabled people since 1980
      • Working in web accessibility and user experience since 1999
        • PhD in the impact of accessibility evaluations on organisations and individuals
        • Run Dundee University’s Web Accessibility service
    • Web Accessibility: people who experience access barriers
      • Impairments that affect ability to access and use web content
        • Visual
        • Hearing
        • Mobility
        • Cognitive
      • Impairments may be personal or environmental; temporary or long term
      • May be age-related
    • Web Accessibility: Supporting disabled people on the web
      • Accessibility solutions
        • Provided by operating system or as part of software
        • Adjust/augment display or mouse/keyboard behaviour
      • Assistive technologies
        • Hardware and software
        • Supporting input: alternatives to the mouse or keyboard
        • Supporting output: screen readers, screen magnifiers, Braille display devices, changes to appearance of web pages
      • How Assistive Technology Works: YouTube Video Demonstrations: http://bit.ly/ATtny
    • Web Accessibility: Best Practice from W3C
      • Web Content Accessibility Guidelines (WCAG)
        • Content must be perceivable
        • Content must be operable
        • Content must be understandable
        • Content must be robust
      • User Agent Accessibility Guidelines (UAAG)
        • Browsers and assistive technologies
      • Authoring Tool Accessibility Guidelines (ATAG)
        • Web content authoring tools – from professional software to Facebook
    • Web Accessibility: Drivers
      • Legislation
        • Promoting equality, outlawing discrimination against disabled people.
        • May also influence procurement practice
      • International and National Standards
      • Organisational policy
        • influencing procurement; influencing markets
      • Industry adoption
        • Web Standards movement
      • Campaigning and advocacy
    • Web Accessibility vs Design for older users
      • Much research into supporting older people as technology users
      • Older people benefit from accessible web design
      • But…
      • Web accessibility assumptions that may not hold true for older web users :
        • Users have extreme accessibility needs
        • Users know they have accessibility needs
        • Users have implemented appropriate accessibility solutions or assistive technology
    • Web Accessibility vs Design for older users
      • Older people are unlikely to self-identify as disabled…or as older people
        • Resistance to use of accessibility features even when made aware of them
      • Capability change is dynamic over time
      • And additional cognitive and social challenges may face older web users
      • So browsing set-up may be suboptimal
      • So accessibility may still be limited
    • Supporting older web users: challenges
      • Reforming web accessibility best practice to consider additional needs of older people
        • Enhancing web author awareness of these needs
        • Close the gap between ‘technical’ and ‘human’ accessibility
        • WAI-AGE project http://www.w3.org/WAI/WAI-AGE/
      • Improving browser usability
        • Short-term: dealing with browser usability issues
      • Capability detection and accessibility adaptation
        • SUS-IT project
