As a visually-impaired person, this is of interest to me generally. That said, I’m not visually impaired enough to really need any special adjustments made but making it user-friendly and being patient with the end user counts for most of what I need.
I actually go to a blind and visually impaired charity called Galloway’s Society for the Blind. They have offices in several different places in Lancashire, as well as in Southport. I wonder if they’d be interested in this kind of thing? They have a technology group (I know that’s not quite the same thing) and I bet they’d be quite interested in something like this.
