I made a demo of a menu system where buttons appear above each finger when the user turns their palm upwards. The buttons follow the user’s hand movements and track towards the user’s face. The buttons also have a hover state when touched with the other hand.
I originally wanted the hover states to occur when the user touches their fingers with the thumb on the same hand, I’ll have to experiment more to see how Bezi could handle this type of interaction. I’d also love to be able to add occlusion where my right hand would hide the buttons as it moves over them.
