I’ve been wanting stuff like this for 25 years. To me, this represents a much bigger step towards creating a real Holodeck than most current display technologies.
Still, it isn’t just the keying of animations that needs to be voice controlled. Directing actors and directing AIs is still a world apart in quality, subtleties, and expressiveness of emotion. In their case, they get some extra realism from using motion capture, which helps. Nice work overall.
