This is probably too late for the contest, but I'd still like to play with QCAR even after the contest. Staring at the QCAR Hands Logo image too much reminds me that... One of my quirky New Years Resolutions is to learn ASL... So, might as well try learning ASL with some nifty Augmented Reality ASL "3d flashcard spelling blocks" (and, eventually scrabble o.O)
The brute force way to make something like that in Unity QCAR is to just lay out all the frame markers and assign each hand model to each marker.
Is there a way to know which marker is being tracked, and to assign a model to the marker being tracked?
