I was thinking of something like this for hand tracking. I was thinking you could maybe attach some sensors to your forearm, do a bit of machine learning and human adjustment to get the signals corresponding to an avatar rig correctly, and then you could pose your hand maybe without anything even in or on your hand.

Damn, your video makes me want to try this out. I think the only big problem is finger splay, but I guess splay could be measured in another way.
