What company do you work for? This is super cool.
Can you talk about the rest of your stack? Or other projects of a similar nature?
The setup was essentially an app (c++ engine on osx running models), ingesting camera feeds, outputting skeletons, running sound->mouth poses, to unity which puppeteered 2D sprites.
On-set we output to a monitor which mixed the real shots with our graphics.
Nothing crazy! But it was a solid setup (except for overheating DSLRs)
It looks like the interface returns 2D coordinates for the joints, not 3D coordinates; so it can't directly create 3D animation data.
It was also very jumpy in my browser, so it would require smoothing to be usable; or maybe if it wasn't running real-time it would be more accurate?
