Gaming with disabilities

Use some kind of pedals? I read about someone years ago, who did not use a mouse but some kind of input with his feet. Maybe it is possible for WASD.

Sometimes there is this "review" on certain games from a guy from Belarus, playing games without any hand and think just his chin.

Can't find a link that quickly.

There is a speedrunner with the nick halfcoordinated who is just like that, can only use one hand, yet he has some world records in action games (including some high-tier competitive times for Platinum Games titles). You may want to look up what he uses.

you say your hand... only the hand or the whole arm? maybe use a trackball/touchpad with left wrist/elbow for WASD?

You can also use the Xbox Adaptive Controller: https://www.youtube.com/watch?v=wEKIAHrugZ4
You can customize it however you feel like and it's compatible with every PC game.

Can you use something like this?

Assuming your fine control and buttons is all on the fancy mouse, you can just set this for movement control in FPS and things like that.
Some games might be more difficult, need a utility to help with bindings.

Could be a trackball for the left hand (to do the WASD) and pedals (missing buttons) a solution ?

Left hand for mouse and right on keyboard?

That may be a stupid question, but have you tried using arrow keys instead of wasd? Being isolated, might be easier for you to use. Otherwise I suppose you could learn using a joystick with your foot, which sound hard to do but faeseble ; or just get some pedals.

Also what about your thumb? You could use a steam controller to move with your left hand.

thanks guys for helping.. but none of those were really what I was looking for.. however after hours of googling i found my answer.

My suggestion would be to use both a keyboard and a controller - some games can detect multiple device input without a problem, so you could assign the directional keys (WASD) to a controller's thumbstick, then place it on your desk and use that with your thumb/palm.

I really can't help and saw that some people were already able to help you out, at least a little bit. But speaking in general, this is a topic that needs to get way more awareness in the gaming world. People with disabilities are gamers, too. Sometimes they have to stop gaming because of their disability*ies. The world should develop more solutions to help them being able to pick up their hobby again. After all, the world should be all about inclusion, shouldn't it? Well, a man can dream, because we don't even have an accessible world, so an inclusive world will not be realized before the first step is taken.

maybe if you contact people here https://www.specialeffect.org.uk/ they can find way to help you,or you can find an hacker/modder that maps pc keyboards buttons to an arcade controller or stick so instead of use fingers you use other parts of hand or arms for move or push.
p.s. im not an hacker , is just my idea how u can fix maybe.
