Computer users who are blind don't use a GUI. They may use The operating system which most people recognize as a GUI, but the access software's job is to beat the interface in to a form that at least resembles a full-screen application if not a command line. I want to be very emphatic in that there is no magic out there that understands graphics and does something useful with them for blind folks. Graphics are silently ignored and may as well not even exist. That is why images that do anything such as links, etc, need alt tags that contain a clue. The only thing we actually use out of the whole interface are alphanumerics. Screen readers can look for certain colors or other attributes in text, but it has still got to be text. Jim is correct about standard functions. They make access easier because everyone knows what to expect. This is nothing more than the mark of a good operating system and design practices and actually has nothing to do with whether it is a GUI or not. All I want is to be able to read useful information, play audio when it is there, be able to type data in to forms, and actually use the content of various web sites. Most of the problems I know of are more brutally technical than conceptual. The darn thing just doesn't work at all. The javascript support we want is simply to actually get something useful when selecting a link. The occasional garbled table or confusing form is nothing compared to a blank screen or no links at all in a page that should be full. If there is any confusion at all about what computer users who are blind find frustrating, that kind of mas malfunction is it. All the big Dollars spent on screen readers and commercial software represent attempts to get more plain old text to appear in the path to the speech or Braille device. It may also be that the computer user wants to use a certain media player or some similar piece of software, but the most important goal is to read that text. That is what it is all about right now.
