I am currently researching and writing an article (to be posted later) about accessibility in PDF publishing. In particular, I feel that game designers need to really consider how they launch their products in the digital age.
There are a lot of disabled gamers out there, and they deserve the same access to products that everyone else does. It takes a bit of additional effort for publishers, but it’s totally worth it.
To get you started, here is a link to a great resource about tagging PDFs for screen reader accessibility. It’s just one resource and one concern, but it’s the best I’ve encountered for this so far and it’s perhaps one of the biggest and most far-reaching things a publisher can do to make their products accessible.
Hopefully that will get you started on your road to understanding the why’s and how’s of PDF accessibility. Check back later for a more in-depth discussion!
