Does anybody know any good accessibility keyboards/mouse for people with Essential Tremors? The tremors are not super severe but the person that needs it can't use a regular keyboard.

Introduction post:
I'm an amateur artist who works with lasers because lasers don't care if your hands shake #EssentialTremor

I'm a little neurospicey (late diagnosed ADHD) so this might be a bit scattered.

Final peculiarities: I've got an evil eye from a violent cataract back in '88 (who needs depth perception?), a big ol' chest scar (heart/aorta repair), and a deep voice in case you need something to sound ominous!

I travel internationally often enough that unpleasant encounters with border officers wondering why I'm nervous have become a real annoyance. I've printed some business cards now to attempt to cut these encounters short - we'll see if it works... #essentialTremor
