I've spent the last six weeks with my left arm in an immobilizer sling. Six weeks of southern United States summer, of being a day-and-night software developer, of being a gamer, all rocking a sling that straps my left arm to a pillow that is in turn strapped to my torso and neck.
After the first 11 days, I've had some use of my left hand for things like typing, but I have limited wrist mobility and can't reach for things or hold/lift more than about two pounds. I'm in this sling 24/7 until some time after August 4.
Plenty of computer and gaming things become difficult in this situation, and I've been exploring some new configurations to get my gaming in. What's come out of this are some good practices I can take away for basic accessibility in developing games.
