Abstract

The population ageing is a dynamic and progressive process that occurs accompanied by physical and cognitive changes. Following a worldwide trend, demographics Brazilians have demonstrated an increased proportion of the number of elderly in the total population. With this increase in the number of seniors we care to ensure web accessibility for the public. For web accessibility means the user right to access the information network by eliminating barriers. An affordable system that allows everyone, regardless of conditions, performing tasks on the web. Assessment of Human-Computer Interaction is an important activity that can assist in the development of systems, because this way you can judge the quality of user interaction with the system. This study aimed to evaluate the accessibility of the site VIDA, using a combination of two evaluation methods, one without the participation of other users and with the participation of users. To investigate whether the site is within the VIDA accessibility principles advocated by the federal laws, the tool was used ASES, and to investigate how seniors react to the use of the site was used for Communicability Assessment Method, which featured the participation of five seniors. To delimit the search, we selected four features of the system for evaluation, based on exploratory research on social networks, blogs and Internet forums aiming to know what customers are saying about the services offered at the site. The results obtained and analyzed include all problems encountered, as well as what problems are more applicants in the website. With that, we listed some solutions to some recurring problems, which can be used in the future redesign of the site in order to make it accessible to the public elderly.
