Sound chat: Implementation of sound awareness elements for visually impaired users in web-based cooperative systems

This article discusses the implementation of accessibility features for visually impaired people in web-based synchronous and cooperative systems. Based on the sociocultural scenario of affirmation of difference and cooperation contexts established by Web 2.0, we discuss the application of sound awareness elements in Groupware tools through Auditory Icons, Earcons, synthesized speech in a web-based chat system. It is a qualitative, experimental study with internal data validation and an exploratory goal. Data collection and analysis were conducted through protocols applied with real users. The results of the experiments showed satisfactory adherence of those technologies in building sound awareness elements focused on participants using screen readers as user agents.
