Neat stuff. I wonder if one could use a neural network to try to do prediction as well.
Human movements are super stereotyped in the face and you could likely predict with decent accuracy the next frame given the previous frames.

Check out a lot of DisneyResearchHub's videos on YouTube. They are regularly posting research on object/face tracking and projections.
That said as you mentioned faces are pretty stereotyped. We "solved" face mapping two decades ago with Tim Cootes and Paul Ekman's work. We're able to quickly map rough estimates using traditional haar cascade classifiers and Viola-Jones with AdaBoost. Neural Networks may help, but we have other solutions that also handle the problem with "relative" ease (ignoring lighting, occlusion, etc.)

What is the SotA OSS for face tracking these days? I've never been able to make face tracking work without having alignment issues during movement.
I don't know if it's SoTa but previously in a joint academic+industrial project I've had very good success with faceboxes for face tracking and then adaptive Wing loss for facial alignment. With c++ and an ONNX runtime, I achieved very fast and accurate results, being robust to lighting and harsh angles.

You mean lag?

The artistic possibilities of this are really fascinating. Looking forward to what people come up with! Projection mapping interactive art is always mesmerizing
This (older) collab is pretty nice:

Pretty cool. I've had this idea of converting face data into MIDI CC data to use with DAWs or synths, this could be a useful algorithm for it.
Is the source code available?

Not this project, I've seen this something like this done with Google's MediaPipe models to get face tracking data into Max/MSP.

Would love to know how to build such a system but with a normal camera and projector if possible for creative art+tech projects!
Can't mediapipe detect faces at 60fps?
Is good but when you need that extra lens shift camera, it goes from mass market to super niche.
It seems like they've done two things here - the physical optical apparatus setup and the algorithm.
I'm wondering why the physical alignment is so important. Are camera distortion models and mapping, view projection, etc. just too slow or low quality to run?
I suppose I'll have to take a look at their paper later.

Or for fake propaganda videos. Dangerous time for these kinds of progress.

What sort of propaganda do you forsee this enabling?

Uh... this is a white paper about projecting an image onto a moving face. Not super imposing, but projecting... with a projector... using light... so what exactly are you worried about with this tech? Or is it just that you're afraid of face tracking in general? And it's not really about this topic specifically?
It’s about high speed face tracking.
Can you imagine other use cases than projection?

You don't need high speed face tracking to make video edits, those are not going to be done in real time.

truly smart, smart home that can track and respond to gaze, e.g. "can you turn off that light" and it will turn off the light they're looking at

That said, it looks like the tech currently works at 1-2m range. I’d guess this is because that’s an easy range for a projector to work at and provide high res, in which case there’s no reason you couldn’t get a zoom setup going.
Perhaps some enterprising director of the next Disney theater production will put the money in to get this working reliably on stage.
