Interesting discussion. While I’m not part of the low vision community myself, I know a few people that are. One of them has been involved with a project developing the open source NVDA screen reader software. It’s Windows based but last I heard it was pretty capable and a good alternative to the commercial options like JAWS. NVDA also seems to support refreshable braille displays. Being open source it might be an easier option to get it working well with HWW software.
