This is amazing, glad so many are making strides to making videogames more accessible for others.
In high school I was friends with a kid who had congenital amputation for both his arms, however, he was able, with a few home rigged solutions, play games on his computer, on PlayStation, and even would go to the arcade and play competitive racing games, though often by additional 'suffering' brusing, abrasions, and tenderness. I'm very happy tools like this to exist to help those that need them.
