Older people and people with disabilities care!There are many reasons why all Australians need to be connected, and those reasons grow in number and importance each year.
• The internet … presents a significant opportunity for increasing the wellbeing of all of us as we age. We must ensure that older Australians don’t miss out on these benefits. • Susan Ryan, Ruby Hutchison Memorial Lecture, March 2012
• With disability, the web becomes more vital and at the same time more difficult to access.• Graeme Innes, July 2012

How are people affected? Many disabilities impact access to print and the web:
◦ Visual (e.g. colour blindness, low vision, blindness)◦ Auditory (e.g. hearing loss, deafness) ◦ Physical (e.g. limited motor skills)◦ Cognitive and neurological (e.g. difficulty reading,
concentrating, understanding, remembering)◦ Users may have multiple disabilities (e.g. a deaf-blind user,
older people)
Plus situational requirements …

Apply some standards?
Web Content Accessibility Guidelines 2.0
• Perceivable• Operable• Understandable• Robust
![Page 19: Happy webusers - World Information Arcitecture Day 2015](https://reader030.vdocument.in/reader030/viewer/2022032421/55a7870c1a28ab7c188b4716/html5/thumbnails/19.jpg)
Accessible web content
Requirements include: Readable and understandable text Identifiable and understandable links Clear and identifiable headings Good orientation and navigation
WCAG 2.0 addresses these
![Page 20: Happy webusers - World Information Arcitecture Day 2015](https://reader030.vdocument.in/reader030/viewer/2022032421/55a7870c1a28ab7c188b4716/html5/thumbnails/20.jpg)
Usability improvementsUsability improvements especially help older people and people with disabilities:• Page layout and design - provide consistency and avoid
overload • Text presentation - use left justification, increase line spacing
& margins, avoid italics and underlining• Forms - avoid complexity and provide clear guidance • Menus and links - provide predictability and consistency
WCAG 2.0 also addresses these
![Page 21: Happy webusers - World Information Arcitecture Day 2015](https://reader030.vdocument.in/reader030/viewer/2022032421/55a7870c1a28ab7c188b4716/html5/thumbnails/21.jpg)
Websites for Older People:How WCAG 2.0 AppliesPerceivable• Text size• Text style and text layout• Color and contrast• Multimedia• Text-to-speech (speech synthesis)• CAPTCHA
Operable• Links• Navigation and location• Mouse use• Keyboard use and tabbing• Distractions• Sufficient time
Understandable• Page organization• Understandable language• Consistent navigation and labeling• Pop-ups and new-windows• Page refresh and updates• Instructions and input assistance• Error prevention and recovery for forms
Robust• Older equipment/software
