Jeff Veen discusses the Macromedia attempt at accessibility for Flash in his most recent post. Flash MX is a great improvement, but still is not all the way to accessibility, and can still keep a well done site from meeting Section 508 compliance. One of the big downsides of the current Flash build is using Flash mixed in a page with HTML. A user must have the ability to use alternate methods to move around a page, which means with out a mouse. This is often done with tabbing or voice commands. Flash does now have the capability to replicate what has been done for years in HTML, but if you add a Flash element into a HTML page the focus never releases from the Flash component. A user can not tab anywhere or even escape from the page as the cursor is stuck. If the person could use a mouse this would not be a problem, but that is not what leads to compliance.
If you use mobile devices the Flash interface is a miserable experience as Flash is vector based and will shrink to fit the screen size. Imagine trying to use a screen designed for 800 pixels wide on a 220 wide mobile screen. Forget it.
The forms in Flash are not quite ready for prime time either. I was at a rack server trying to update information in a Flash form on the Macromedia site and I was tabbing because the hyper trackball was horrible. Flash walked me down the page, but the focus moved under the bottom scroll bar with out bringing the screen focus up so I could see the form box I was having to deal with. This is flat out unacceptable, as HTML has had this right for years. Not only that, but I had a validation error and the alert was placed at the top of the Flash screen and out of site as it had scrolled up. The ability to scroll or move the screen until the alert was clicked was disabled, this took expanding the screen to full size to click the bottom of a button on the alert that I could not read.
Flash needs a motto like, "Flash -- the tool that gives uneducated interface developers the ability to create unusable forms and user experiences just to have buttons and scroll bars with indiscernible color shades" or "Flash -- for interfaces you don't want people to use"
Macromedia seems to have taken large strides with Flash, but then just stepped right over the cliff.
