David,
It's very unlikely that this type of OCR could solve a CAPTCHA. (Note the
spelling.) They are designed to defeat OCR programs. Even visually, they are
difficult to read.

Just a question here:
Would such a feature as Onscreen OCR give the user a chance of solve captures
on webpages? Or, is that a different beast?
Yes, I know of Selowna and Webvisum. But both of these services have had
their instabilities lately. I really wish there was a feature directly in WE
(or with an app), to solve these challengers.

All you app writers out there, as you follow Aaron's links to the OCR
resources, keep in mind that as you design your app, the results of the
on-screen OCR should appear in a window and allow the user to place the mouse
pointer on the item to be clicked. The user should also be able to select the
part of the screen the OCR will act upon, current control, current window or
entire screen.
I am very happily discovering the titles of the episodes in my DVD
collection with JAWS 13 Beta, rather than just hearing title 1, title 2, etc.
I'm sure I'll run into one of those inaccessible setup programs one of these
days that I've always just rained curses on in the past. The companies that
write these programs should make them accessible, but how many have you
persuaded to do so?
I almost forgot, if you have ever tried Kindle for PC with Accessibility
Plugin, you probably know that there is no text accessible to a screen reader.
I tried Convenient OCR and got results. Unfortunately, since the text is
displayed as it appears on the printed page, a page with more than one column
is a little hard to read. I can see it being useful to get the spelling of
words that the built-in text-to-speech mispronounces though.
I hope that on-screen OCR can be implemented for Window-Eyes with a
well-designed app.

I like the idea of putting it into a script.
OCR through scripting could be done today by anyone with some knowledge
and some free time. I have one of those, but not the other. <grin> Here are
