The aging of Brazilian population increases the importance of the study of accessibility. Tablets devices are winning the market, and the study of their interfaces for the elderly also an important field of research. However, recent studies have found that the WCAG 2.0 do not fully address this scenario. In order to fill this gap, nine new successful criteria for WCAG 2.0 to assist in the detection of accessibility problems in this scenario have been proposed, but they have not been evaluated. This article presents the evaluation of these nine new successful criteria. The methodology was based on recruiting evaluators, separating them into three groups, choosing websites that have presented the problems that gave rise to the new criteria, inspecting the websites and analyzing the results. Results of the accessibility evaluation using the new criteria have shown that they are relevant and help in detecting a greater number of accessibility problems in websites. |
