Summary
This paper reports findings from a remarkable 3-year ethnographic study (2005-2008) of 388 older people (aged 65-80) using web and computer technologies in their daily lives at the Àgora adult centre in Barcelona. Unlike most accessibility research that relies on lab-based usability tests or interviews, this study used in-situ observations and conversations during actual technology use across courses, workshops, and public meetings — totalling hundreds of hours of observation. The ethnographic data was analysed using Grounded Theory methods (open, axial, and selective coding). The 350 participants with lower education (primary school or less) had never used a computer before; the 38 with higher education had some workplace technology experience. Participants' motivations for learning the web were social: not falling behind society, staying connected with family and friends, and enjoying learning opportunities they missed in childhood.
Key findings
The study revealed a surprising prioritisation of accessibility barriers that challenges common assumptions. The most impactful barriers were cognitive and motor — remembering task-related steps, understanding web/computer jargon, and using the mouse (particularly double-clicking and text selection) — rather than the sensory barriers (perceiving visual information) that typically dominate accessibility discussions for older people. Participants could interact with standard-size interfaces without difficulty and preferred putting on reading glasses or moving closer to the screen over using magnification tools, which they found disorienting because enlarged content scrolled off-screen, causing loss of context. Words were far more important than icons for navigation — older people learned task names ("copy", "paste", "search") rather than icon meanings, and relied on consistent terminology across sessions. Inconsistent use of terms like "close" versus "delete" was more confusing than small icon sizes. The mouse was described as simultaneously essential and problematic: participants struggled with mapping physical movement to cursor movement and with double-clicking precision, but strongly rejected alternative input devices like joysticks because they associated them with children's video games and disability — "Being old is not being handicapped!" The desire for independence and inclusiveness (using the same tools as everyone else) drove technology choices more than functional efficiency.
Relevance
This is one of the most methodologically rigorous studies of older people's web accessibility, and its findings challenge several widely-held assumptions in accessibility practice. The finding that cognitive barriers (remembering steps, understanding jargon) and motor barriers (mouse control) outweigh visual barriers in everyday use suggests that the accessibility community's emphasis on visual accommodations for older users may be misdirected. The strong desire for inclusiveness — using mainstream tools rather than "accessible" alternatives — has profound implications for how accessibility features are designed and presented. Solutions that make users feel different or disabled will be rejected even if they are technically superior. The emphasis on consistent terminology over icon design, and on reducing cognitive load over enlarging visual elements, offers concrete design guidance: clear, consistent labels and fewer steps matter more than bigger buttons. The 3-year ethnographic duration and 388-participant scale give these findings an ecological validity that lab studies of a few hours with a dozen participants cannot match.
