Aging

Aging is the biological, psychological, and social process of growing older, which in accessibility practice is associated with a predictable cluster of changes: declining near and low-contrast vision, hearing loss at higher frequencies, reduced fine motor precision, slower response times, and changes in working memory and attention. Because these changes typically arrive together and vary widely across individuals, older adults form one of the largest and most diverse accessibility populations. Design practice that treats 'seniors' as a single simplified audience — by stripping features, enlarging buttons, and calling the job done — tends to underserve the population; modern inclusive-design guidance instead emphasises configurable text sizes, flexible input methods, predictable interaction patterns, and respect for the breadth of goals and abilities among older users.
