Guideline for Designing Accessible Systems to Users with Visual Impairment: Experience with Users and Accessibility Evaluation Tools

Caroline Guterres Silva, Vinicius Coelho, Marcos Alexandre Rose Silva

Abstract

Nowadays, society uses computer systems in diverse day to day activities, such as shopping, social interaction, study, research, etc.; however, a considerable number of the population, who has some kind of special necessity, faces difficulties in using those systems for various reasons, for example, there are codes not written in a way that allows screen readers to identify the menus, contents, etc., to make the correct reading for users. In that context, this paper contains the description of a research done to identify guidelines and/or techniques that address a code document to facilitate interaction between the visually impaired and computer. By applying those guidelines to a prototype and then submitting it to testing with visually disabled users, it was observed that the source code was more legible for screen readers and user interaction was facilitated; however, during user testings, improvements that could be applied to the existing guidelines were observed. Beside user testings, this paper reports a research on automated validators and their criteria on source code's accessibility. It is noted that this automated verification does not exclude tests involving users, because both tests are important in the process of accessibility assurance.
