I was contacted by Johel, who has Muscular Dystrophy. While he can use his left hand, his usage is severely limited on the controller. For Johel I came up with 2 new trigger systems to allow for lateral transfer of force.
The ps4 has some pretty wiggly shoulder buttons, so I had to use a simple lever attached to the side of the controller for the shoulder button. The trigger is still solid enough for me to attach extensions directly to it.
This is the first time I’ve experimented with adding a tiny screw to hold things in place. I hope they last.
