Augmented reality tracking will soon completely replace MOCAP for film making, this early puppetry example 2020CV shows how intricate and responsive hand gesture tracking has become.
OK this is a very simple 2d animation but there are obvious immediate uses for education and live animation.
Using the same tracking techniques you could then convert anything into anything.
Hands into puppets
Hyundais into Ferraris
Jennifer Lawrence into Steve Buscemi
We are currently using the same techniques within Aero Ranger to live augment new developments into the Perth cityscape.
