A patent from Nintendo suggests that they're working on a magnetic joystick system, aka hall effect joysticks, which would solve stick drift.
A patent filed by Nintendo suggests that they’re working on Hall Effect style joysticks for the Switch 2 that would eliminate stick drift almost entirely.
Joycon drift, and all other thumbstick drift, is already a solved problem.
Use bushings that actually have some abrasive resistance and aren't softer than a fingernail.
Use a non-contact based sensor to determine the XY position of the stick. Hall effect, optical, strain gauge, whatever, we've had the tech for 50 years.
The reason why they haven't done this is one very simple reason: $$$
N64 does use optical sensors, the n64 stick is actually super precise and doesn't suffer from drift. The n64 is a goofy controller but it is simply a great and accurate input device, and a lot of the games were really designed with that stick and notches in mind.
But it is made of all plastic and features plastic on plastic moving parts, without lubrication, so it suffers from wear of the plastic. Worn n64 sticks will actually be filled with plastic dust from the stick and gears literally sanding themselves down. The only problem with the controller is the premature wear of the stick.
It's crazy to me that no company ever made a decent 3rd party N64 controller. The 3rd party ones were all as ridiculous as the defaults. Great console that I loved, but would have gotten a lot more out of with better controllers.
there was a hori n64 controller that looked like a normal double handle controller and it was really good, but it's crazy expensive these days on ebay. I've also heard good things about the new brawl64.
The Hori Pad Mini? I had never seen that before, leagues above anything I remember being available at the time. The other looks amazing, definitely a modern controller that I would have killed for back then.
The sensors on the N64 are basically the same kind you'd find in a mouse wheel. They work fine.
The crap part is the physical construction. There's a lot of parts that wear down with use and cause the joystick to become loose due to the plastics wearing away.
Yup. If they'd just made the bowl out of something OTHER than ABS, they would have been good. Delrin, PTFE, even a thin layer of brass or broze, and those controllers wouldn't have had anywhere near the amount of issues they're known for having.
There are third-party manufacturers who sell replacement bowls and sticks, made from everything from POM to steel.
the reason the n64 sticks suck is down to the stick tension construction and not really the sensing mechanism. Pretty much the thumbstick was pressed against a plastic bowl that wore away into white dust through use, making it floppy. it didn't really have anything to do with the fact that it was an optical stick
