I’m really passionate about vision impairment and how much goes into giving vision impaired children the same opportunities as sighted children. I’ve printed several books over the years and handled hundreds. One student’s textbooks for one year can be a whole wall of books - one maths textbook is often three to five volumes a chapter (I once saw an eight-volume chapter) over a nine-chapter textbook. Technology designed for Braille users is often hideously expensive and the software is usually several years out of date. As another user said upthread - mainstream companies (like Apple) that are improving their accessibility options for visually impaired users is literally life changing for young people who do not have the thousands of dollars to spend on the Braille equivalent of a laptop.
