Making the Case for Age-Friendly Design
@neyricardo • IxDA Redux Campo Grande
Design for older adults, and you design for almost everyone else. [Alan Newell]
Populations with similar usability issues:● Those with low vision or other impairments● Those with low literacy● Those with little technical experience● Those with obsolete technical experience● Second language learners● Those with certain cognitive impairments
Many Adults, Not Just OAs, Have Hearing, Visual, or Motor Impairments

Individual Variation
@neyricardo • IxDA Redux Campo Grande
● Aging is a continuous process● Change is not linear, or uniform● Effects of aging are highly idiosyncratic● As group’s average age increases:
○ Rates of change in abilities increase○ Ranges of abilities increase
Tech can be transformative...
@neyricardo • IxDA Redux Campo Grande
● Faster computers● More colours● More pixels● Sensitive sensors● Accessibility improvements
... but all is NOT WELL
@neyricardo • IxDA Redux Campo Grande
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!
Who thought grey thin letters would be a good idea?
My limitations frustrate me but I don't know where to get help.
All the new technology is so confusing to me.
It's embarrassing to have to ask my grandkid's help
