PS5 and Xbox S have hall effect sensors by default now. The Switch Joycons had lots of drift from the less durable potentiometers. There was an article about 3rd Party hall effect upgrades to Joycons here: https://gizmodo.com/gulikit-hall-effect-stick-nintendo-switch-joycon-drift-1850007363 https://gizmodo.com/gulikit-hall-effect-stick-nintendo-switc... ------ Hall effect sensors are fundamentally just cheap, but highly accurate, magnetic sensors. They are used for compasses inside of cars and such. But with today's technology, hall effect sensors can very precisely determine the positioning of magnets. So place a magnet inside of a joystick, and bam, hall effect sensors can triangulate the position. ------- The older potentiometer based method is just a variable resistor + brush. As you move it around, the brush changes the resistance of the erm.... resistor. But this brush eventually wears out the internal parts from hundreds of thousands of movements (and video gamers can hit that kind of usage in practice) Because the magnets + hall effect sensor has no brush, we no longer have to worry about the brush rubbing + wearing out the internals.
