We present EgoReAct: Real-time 3D human reaction generation from streaming egocentric video. 🌟Reacting to streaming egocentric video is something humans do every day. We hope EgoReAct makes human motion more human-like. 🔎 What we found: existing ego-reaction data can be spatially inconsistent (e.g., moving reactions paired with fixed-camera videos),...

EgoReAct solving ego-reaction generation from streaming video is brilliant. Using existing ego-reaction data = building on proven patterns. This will transform VR avatars, motion capture, and digital humans. Human-like motion is now generatable at scale, not handcrafted.

This is such a abstract idea lmao. Makes sense using a planner and then generation. How long it generates till the architecture blows up? Great work though!

Hardware companions always feel like a solution looking for a problem.

Thanks for your comment! Just to clarify, EgoReAct is entirely software-based and focuses on real-time 3D human reaction generation from streaming egocentric video (the video can be from a common video recording device). We’re working on improving the generation of human reaction from egocentric video streams, which can be a good tool for AR/VR, animation, robotics, and beyond.😊

Thanks yeah - it's brilliant. The point is the hardware/physical layer is such a limiter... you're going the right way!

🙇‍Appreciate it! Yes—I think standard RGB cameras already work well for our setting, but better devices will always be helpful! Besides, we definitely need to further scale the model up for stronger generalization.
