Extended working career

Age Commissioner:• “A recent Deloittes report on the looming national skills

Impact:•Audio can be difficult to discern •Higher pitch sounds can be missed

Prevalence: •47% of people 61 to 80 years •93% of people 81+ years

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

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

Numbers online (2006)

ACCESSIBILTY FOR OLDER PEOPLE

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/ageing

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%

ROLE OF WAI GUIDELINES

Components of web accessibility

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

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

WAI-AGE OUTCOMES

WAI-AGE goals

• Raising awareness of Web accessibility for older people

• Better explaining the applicability of the WAI guidelines for older people

• Avoiding potential fragmentation through reinvention of requirements

• Encouraging participation of older people in W3C/WAI standardization

WAI-AGE resources

Revision of existing WAI resources, including:

• Developing a Web Accessibility Business Case for Your Organization

• Before and After Demonstration (BAD) website

• Involving Users in Web Projects for Better, Easier Accessibility

• Developing Web Accessibility Presentations and Training 

WAI-AGE resources

New WAI resources:• Better Web Browsing - Tips to customize your com

puter• Contacting Organizations about Inaccessible Web

sites• Developing Websites for Older People• How to Make Presentations Accessible to All

Websites for Older People:How WCAG 2.0 Applies

Perceivable• 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
