web accessibility, usability, older adults, evaluation methodsAbstract
The constant evolution of the Web has covered various segments of society and, as it evolves, its content must be accessible to different users’ profiles. Older adults (60+) are the fastest growing population of users who face difficulties in interacting with websites, due to limitations in their abilities caused by the aging process. Despite the legislation and guidelines established for the development of accessible and usable web contents, several problems of accessibility and usability still must be solved. In particular, most website designers do not take into account the older adult’s profile. This paper introduces Sene-check checklist, a support to web accessibility and usability evaluations for the Brazilian older profile developed according to scientific procedures, including the following three perspectives: (1) literature review, (2) point of view of experts and developers and (3) point of view of Brazilian older adults. The results enabled an investigation into the main problems encountered by older adults regarding web interaction and reinforced the relevance of a support for the evaluation of web accessibility and usability.
