The long story: I have an undiagnosed disease/syndrome which, among other things, makes my fingertips become red and cold during winter season, and it gets worse when I'm typing. So in the summer I can pretty much type all day. It's not that my hands don't get cold while playing video games on my Playstation controller, they just get worst. I assume that the impact on every finger makes it worse, because I can wear all the layers of cloth in the house + have the air condition turned on and all I can get is my face and ears all red, but the fingers still cold as ice cubes.
From my standpoint, I see the potential use as an accessibility tool. If I can write words and avoid the step where my fingers suffer the impact of every keypress that's a big win for me. It's not like I can't type (obviously) but I'm wondering if I could train myself to code using something like this to avoid discomfort. I once entertained the idea of using my PS4 controller since Steam uses something similar.
