Designing for an Aging Population

1,223 views

Published on

If a website or app’s target audience includes older adults, certain aspects of its design become more important. This talk describes age-related factors that affect ability to use websites and apps, and presents design guidelines that reflect the capabilities, usage patterns, and preferences of older web users.

Features:

demographics of users of digital technologies, by age
age-related factors affecting ability to use computers, mobile phones, tablets, and other digital technology,
common design problems that decrease usability for older adults,
design guidelines that can help designers avoid these common problems.

Designing for an Aging Population

  2. 2. Finn & Johnson, Wiser Usability, UXPA 2016 2 3 Making the Case for Age-Friendly Design Design for older adults, and you design for almost everyone else. [Alan Newell] PopulaJons with similar usability issues: •  Those with low vision or other impairments •  Those with low literacy •  Those with liGle technical experience •  Those with obsolete technical experience •  Second language learners •  Those with certain cogniJve impairments 4 0 10 20 30 40 50 Hearing Visual Motor 18–44 45–64 65–74 75+ The Case for Age-Friendly Design: Many Adults, Not Just OAs, Have Hearing, Visual, or Motor Impairments Age Source: Summary Health StaJsJcs for U.S. Adults: NaJonal Health Interview Survey, 2012 (Published 2014) % US adults with self-reported impairments, by age group.
  3. 3. Finn & Johnson, Wiser Usability, UXPA 2016 3 5 Individual VariaJon Studies on aging are particularly subject to confounding effects. [Reddy, 2012] 6 Individual VariaJon •  Aging is a conJnuous process •  Change is not linear, or uniform •  Effects of aging are highly idiosyncraJc •  As group’s average age increases: •  Rates of change in abiliJes increase •  Ranges of abiliJes increase

  5. 5. Finn & Johnson, Wiser Usability, UXPA 2016 5 9 Source: PewInternet.org % US PopulaJon Online, by Age Group The Case for Age-Friendly Design Increasingly, Older Adults Are Going Online 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 2000 2002 2004 2006 2008 2010 2012 2014 Year 18-29 30-49 50-64 65+ Age 10 Tech Can Be TransformaJve… A Mac laptop opened up the world to me, right here, from my kitchen table. This is a blessing because my mobility is now extremely limited due to my physical disability. Technology has helped me move 19 times in the past 9 years, taking ‘everything’ with me. I can keep in touch with people all over the world. I feel so connected to so much of the world: art, music, nature, comedy, humanity. I can’t imagine going back to a life without a computer.
  6. 6. Finn & Johnson, Wiser Usability, UXPA 2016 6 11 ...but All Is Not Well So much to remember! I wish they would stop changing things for no good reason. What happened to the menus? How can I make the font bigger? I can’t see it! 12 We Know How to Do Design Right… So Why Don't We? •  Aging is not a “sexy” topic •  Designers tend to design for people like themselves •  Engineers and designers osen have liGle personal experience with OAs •  Designers tend to discount pure data on OAs •  OAs seldom included in design, evaluaJon •  Designers tend to over-esJmate OA tech ability
  7. 7. Finn & Johnson, Wiser Usability, UXPA 2016 7 13 Need for Universal Design Won’t Just Fade Away “Digital NaJves” vs. “Digital Immigrants”? •  Not all young adults are techno-whizzes. •  Technology will conJnue to develop. •  People have trouble with technology they didn’t grow up with. •  Most of us will experience age-related changes.
