Do you know you users?
In Australia our population is ageing:◦ 14% > 65 yrs (2012)
◦ 19% > 65 yrs (2031)
Do you know your users?
Disability in Australia: ◦ 18.5% of population
◦ 50% of people > 65 yrs
Are they online? ~50% of older people are online
Do you care?
In 2012 seniors held over 40% of the nation's assets. Couples between 50 and 70 have the highest median net worth: $900,000!
Amazon does – in 2013 they launched a sub-site dedicated to people over 50
Coles does – after court case Smashing Mag thinks we all should in 2015
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
Unprecedented opportunities for:
Social interaction and communication Access to information Access to eCommerce Access to government services and civic
participation Training and learning opportunities Employment, research, and access to
workplace applications
CHANGING ABILITIES
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 …
Ageing and hearing loss
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
Affects at least 50% of people over 65
◦ Essential tremor Affects up to 20% of people
over 65◦ Parkinson's Disease
Affects approx. 4% of people over 85
Ageing and cognitive decline Impact:
Navigation, comprehension, and task completion can be affected by: ◦ Short term memory issues◦ Difficulty with concentration ◦ Distraction from movement
or irrelevant material ◦ Difficulty coping with
information overload
Prevalence: (Conditions commonly reported)◦ Dementia:
1.4% of people 65-69 yrs 24% of people 85+ yrs
◦ Mild cognitive impairment (MCI) is more common: Around 20% of people over
70 years are estimated to experience MCI
What can you do?
Tackle usability?
http://www.semanticstudios.com/publications/semantics/000029.php
Apply some standards?
Web Content Accessibility Guidelines 2.0
• Perceivable• Operable• Understandable• Robust
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 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
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
