12
Ageing and vision decline Impact: Decreasing ability to focus on near tasks Changing colour perception and sensitivity Decreasing contrast sensitivity Prevalence: (significant vision loss) 16% of people 65 - 74 years 19% of people 75 – 84 years 46% of people 85+ years
13
Ageing and physical decline Impact: (Motor skill decline can result from many conditions including arthritis and Parkinson's Disease) Difficulty using mouse or keyboard Difficult to click small areas Strain from non- ergonomic tasks Prevalence: (Conditions commonly reported) Arthritis At least 50% of people over 65 affected Essential tremor Affects up to 20% of people over 65 Parkinson's Disease Approximately 4% of people over 85 affected

ACCESSIBILTY FOR OLDER PEOPLE
21
Observations from the literature Many studies seemed unaware of the W3C/WAI work Information overload was commonly identified Less technical, more usability, requirements predominated Accessibility options were not appreciated by users Adaptive strategies were seldom considered Assistive technology was not discussed Hearing as an impairment was ignored Draws on http://www.w3.org/WAI/presentations/ageinghttp://www.w3.org/WAI/presentations/ageing
22
Roger Hudson’s survey (2010) Common problems “Silly little picture about nothing” “Fancy stuff that keeps moving” “Finding what I’m after” “Too many navigation choices” Text size or colour Text size sometimes a problem for 48% Colour mentioned by 23% http://kwz.me/Y3 /

ROLE OF WAI GUIDELINES
24
Components of web accessibility
25
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
26
Usability improvements Usability 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
27
Role of web browsers Browsers are the entry-point to the Web: Many older users are overwhelmed by the functionality Accessibility features are often not easy to configure Some browsers do not work with assistive technology People who are new to the Web are especially affected UAAG helps address these
28
Web authoring Older people contribute to the Web: Using content management systems for work- related publishing Using social media applications such as FaceBook, blogs, and forums Developing Web sites professionally or for leisure ATAG helps address these issues
29
