ABSTRACT

Although WCAG 2.0 offer techniques for making web content more accessible to all people, very little is known about how these techniques enhance web accessibility for older people. This paper addresses two techniques, keyboard-based navigation and design of links purpose. They are evaluated by using simple prototypes in the course of designing two websites for old-age pensioner associations. Participants (N=11) ranged in age from 65 to 80 years old and were familiar with web concepts. The results indicated that keyboard-driven navigation did not improve web accessibility. Older people preferred to use the mouse because of inclusiveness, despite their difficulties using it. 'Click here to' links helped participants clarify where they had to click and what would happen after clicking, despite not being suggested by the WCAG 2.0. Click-able pictures should resolve to full size renderings of those images rather than opening a new web page. These findings suggest that WCAG 2.0 do not consider carefully enough some important needs of older people. The paper discusses some alternatives for taking them into account.
