I wear a ring while typing, usually on my index, middle, or ring fingers. Couldn't handle wearing it on my thumb at first because it kept tapping/scraping against the keyboard or the mouse and it'd get distracting in a bad way because I usually rest my entire palm on the keyboard.
I keep it on a chain around my neck on occasion, but if I'm wearing it, then: the way I type nowadays is by resting my wrists on my laptop (or a wrist rest if I'm using a PC) so the part of the finger my ring rests on never touches or comes close to the keyboard.
Those ergonomic wrist rests are pretty good at helping me maintain a decent workflow while compromising with whatever is adorning my hands. They're not necessary though, I usually substitute those with a thick textbook, blocks of wood and whatnot depending on my needs at the time.
