i've heard good things about using the 1 euro filter for user input related tasks, where you're trying to effectively remove noise, but also keep latency down.

see https://gery.casiez.net/1euro/ with plenty of existing implementations to pick from

That sounds very interesting. I've been needing a filter to deal with noisy A/D conversions for pots in an audio project. Noise on a volume control turns into noise on the output, and sounds horrible, but excessive filtering causes unpleasant latency when using the dials.
