→How to develop accessible extensions, modules, and plugins for the BigBlueButton Flash client
With Visual and Motor disabilities there is a common concern of the user being able to navigate through the application, since use of a mouse may not be possible. You'll accommodate this by including your code in the tab order, and also by providing shortcut keys for all user functionality in your code. The rule is, '''if you can do it with a mouse, you need to be able to do it with a keyboard.'''
Some Visual disabilities require the user to have a screen reader, which is what it sounds like: an application that reads out the content of the screen to the user. In Flash, this is done mainly through the accessibilityDescription accessibilityName property. The rule here is, '''all relevant data on the screen must have an accessibilityDescriptionaccessibilityName.''' It may look like a lot of work to develop accessibly, but the majority of the work involved is strictly one-time setup. Once that groundwork is in your code, it becomes a very simple matter to "fill in the blanks" as you add more code.
