Abstract

This study presents an investigation on how keyboard accessibility has been delivered in RIA - Rich Internet Applications. We conducted an evaluation on 32 websites which contained Tab Widgets, from the 150 websites of Alexa's top most accessed websites list. The evaluation process consisted of checking if the Widgets implemented ARIA - Accessible Rich Internet Applications requirements, like the use of role/state semantic attributes and presentation of keyboard interaction strategies. The results showed that, even though the ARIA specification achieved the status of W3C Candidate Recommendation in 2011, few websites implemented Tab Widgets according to ARIA in the Web. The study also identified alternative keyboard navigation mechanisms that are accessible to Assistive Technologies users, despite the disadvantages they might represent.
选项卡部件中的键盘导航机制:对ARIA一致性的调查
本研究对键盘可访问性是如何在RIA - Rich Internet应用程序中实现的进行了调查。我们对32个包含Tab Widgets的网站进行了评估,这些网站来自Alexa访问量最高的150个网站。评估过程包括检查widget是否实现了ARIA - Accessible Rich Internet Applications的要求,比如角色/状态语义属性的使用和键盘交互策略的表示。结果表明,尽管ARIA规范在2011年达到了W3C候选推荐标准的地位,但很少有网站根据ARIA在Web中实现Tab Widgets。该研究还确定了辅助技术用户可以使用的替代键盘导航机制,尽管它们可能存在缺点。
