Here's some more info on accessible leisure from my post there:
Some useful information on people facing barriers in game accessibility can be delved into here (see the forums section especially): http://switchgaming.blogspot.co.uk/2009/07/game-accessibility-sites.html and here: http://switchgaming.blogspot.co.uk/search/label/Design%20Tips
It's not too hard to imagine some of the barriers people might be facing in leisure with physical activities, if they can't freely get around. Sometimes the requirements are too demandingly precise / out-of-reach / too strenuous / too painful.
- The Wii remote and Playstation Six-Axis have long been a difficulty for many physically disabled players.
- VR games provide similar difficulties. Imagine being unable to move your neck but desperately wanting to interact with something VR only.
- Sports like Bowling, Pool, Golf etc. are hard to have full independent control over for someone unable to use the traditional kit.
- Barriers to toys that are fun to play are legion. Think about sight/hearing/physical/cognitive barriers.

A lot of the stuff above is either rare, out-of-reach expensive or just a one-off. So much could be done for boosting access to leisure and creative opportunities. Sometimes people won't ask for stuff because they have no idea it's possible. Definitely a good idea to try to track down some people to try your creations who are facing barriers.
