Question Plotting Thumbstick Motion as an Instruction

Can anyone tell me how would I go about tracking the movement of an analogue stick for a certain period and use this input to affect an action in-game? For example, if I were to move the right stick in an up/down motion, or sweep from down around to the right. Fans of certain popular skating games might know what I mean...

 

This is broadly referred to as input gesture recognition.

Fighting games use it a lot, like for "hadouken" style attacks.

I made one for VR "Yes" and "No" head movements (source in comments):

Otherwise, check out some actual Youtube tutorials. There's a lot of choices and a lot of details to it.

 

Thanks very much for the info, I'll be sure to check it out. And there's a name for it, "Gesture Recognition", that's useful to know!
