DESCRIPTION
You rarely see the terms Flash and accessibility used together in a sentence, and yet the Flash Player has had the ability to integrate with assistive technologies for almost six years. In this session we'll dispell the myth that all Flash content is inaccessible, and show you how Flash can help to tackle accessibility issues that go beyond standard assistive technologies such as screen readers.
