It is absolutely amazing that nobody seems to have clicked through to the actual article.
So for all the "just use hall effect sticks" people, the patent is apparently not just for a solution to drift but also a way to add variable pressure to sticks, kinda like what Sony does to triggers.
It took me like fifteen seconds to read deep enough to find that.
For what it's worth, I think it could be interesting, especially if applied in a Nintendo-like way, bur proprietary stuff like that tends to go underutilized. You know, like the triggers on the PS5 controller.
