All of the above. I believe automation apis such as windows UI automation, COM or applescript all contain valuable information for accessibility (some more than others). Whether that is simply all the text displayed on the screen (not that getting that done is simple) or conversion of a complex series of mouse clicks into a simple operation. I think system automation apis are comparable to accessibility apis. As one improves so should the other. Would be interested in discussing further.
