Alex McLeanSay you are working with eight sensors on the body.. Is there some (free/open source) library for live processing that in different ways.. Like taking rolling averages, measuring changing energy levels etc? + gesture classifying as well but also the basic stuff.. There must be standard ways of doing this in e.g. puredata?

@yaxu I don't think I've seen "higher level" stuff like whole classification tools other than things tied to specific hardware (and not f/oss) - it's task-specific enough that people tend to just roll their own thing. there are good base libraries such as labstreaminglayer, though
@yaxu (tool tied to specific hardware: https://biosignalsplux.com/products/software/opensignals.html despite the name, of course, not open whatsoever, and has a few plugins to analyze specific kinds of data, that cost... a lot of money)
@yaxu in general, I'd recommend getting familiar with scipy and a ML library of your choice (sklearn / pytorch / tensorflow / god knows what), if you aren't already, and then using those + labstreaminglayer to build up what you need (or maybe someone has built something based on LSL that matches your problem roughly, then you can go from that - i.e. there's lots of tools for EEG stuff specifically already, iunno motion as much but I know colleagues did record motion data through it)
@halcy great thanks for the pointers!
