Blio is an ebook reader written in .net. There are two issues which mean braille can't be used to read books:

  1. It uses a role of document for its book content area. However, braille doesn't treat this as a text object. We should add document to the list of roles accepted by braille.NVDAObjectHasUsefulText.
  2. Once the first issue is fixed, braille does not track the cursor. In turn, this means you can't move to the next line with braille. This happens because we disabled the UIA !TextSelectionChanged event (#1205, 9025c04). Unfortunately, #1205 apparently occurred in Windows 7 as well, so re-enabling the event would re-introduce this.

Mick, any thoughts on (2)? The best I could come up with is to selectively listen for these events only for certain objects, but we've run into problems with object event registration in the past.

As a sidenote, (1) is also valid for Digital Editions, but unfortunately, it doesn't fire !TextSelectionChange events even when we listen for them.

Unfortunately, we had to revert part of this fix in 0df44ab, as it was seriously breaking Adobe Digital Editions and other applications used by users. We'll try to find a better fix in the future.

@jcsteh: Should we close this as won't fix in favour of kindle/QRead, which are both accessible solutions now?

@jcsteh, @leonardder, any further thoughts on this? Is the support for braille in this application still an option? or should we close it?
