The latest in our Flex-related series of tutorials focuses on something that all web designers and developers ought to embrace: accessibility.

Author Toby Tremayne (a specialist in advanced development and data driven interaction design) begins by giving us a clear idea of what accessibility is, and why it matters. He then goes on to outline the four major types of user-impairment (visual impairment, dyslexia, motor disabilities, and cognitive disabilities) that are most likely to affect accessibility and present challenges to designers and developers.

Shifting the conversation specifically to Flex apps, Toby shows us how to enable accessibility by modifying the Flex configuration. He outlines the accessible components in Flex before touching on the issue of screen readers, fonts and colours, and keyboard access.

In concluding the piece, Toby suggests that accessibility is a task worth tackling right from the very beginning of application building. He also mentions a few websites that are useful for further reading on the subject.
