Evaluation of the Accessibility of Websites by means of Software Metrics
Abstract
The Internet experienced several advances that allowed global access to increasing levels of information in diverse formats and contents. However, people with visual disabilities face many accessibility barriers that hinder the adequate understanding of Web contents. In Brazil, the Federal Government possesses an initiative, via Decree Law, that stipulates the mandatory accessibility to Governmental Web sites content. In this context, it is necessary to define how to evaluate accessibility to support the quality of these sites with respect to this aspect. Therefore, this article proposes a means of Web accessibility evaluation through software metrics.
Keywords:
Software Metrics, Web Site Accessibility, Evaluation Method
