ZipSplat: Fewer Gaussians, Better Splats
@veichta, Sunghwan Hong, @majti89, @mapo1
tl;dr: predict Gaussians directly in 3D from a compact set of scene tokens->decouple primitive placement from the 2D pixel grid

1/ Excited to present FunREC: "Reconstructing Functional 3D Scenes from Egocentric Interaction Videos" at #CVPR2026! FunREC builds functional, interactable 3D digital replicas of real-world environments from a single egocentric interaction video. 👇 Here's me turning my own kitchen into a functional 3D digital twin, just by interacting with it. 🔗 Project page: functionalscenes.github.io 📄 Paper: arxiv.org/abs/2604.05621 🗓️ Poster: Session 4 (#654), Sat Jun 6, 16:45–18:45, ExHall A

@meta_aria This is very cool work! It’s a more unscripted version of what we did with HoloAssist (holoassist.github.io). I think these type of datasets are very valuable given the rich and purposeful interactions they capture.

How do we train AI to be a real-world expert? 🛠️🧠
Introducing Ego-EXTRA, a new video-language dataset for Expert-Trainee assistance. Researchers at the University of Catania captured unscripted interactions where experts guide trainees through complex tasks in real-time using Aria Glasses.
👓 50 hours of data
💬 15k+ high-quality VQA sets
✅ RGB + Eye Gaze tracking ✅ Hand keypoints & SLAM ✅ IMU, Magnetometer, & Audio ✅ Natural expert-trainee dialogue
🚲 4 scenarios: Bike Workshop, Kitchen, Bakery, & Assembly

Very serious question:
Why is 12pm noon and 12am midnight?
7am
8am
9am

@SavinovNikolay @TeplyashinDenis @machelreid This is really cool. Always exciting when former students do great things! Looking forward to catch up.
English
I was leading long context in Gemini for a while now, and today I’m proud to share what the team has achieved: over 1M context in a large-scale foundation model.
Big shoutout to @TeplyashinDenis and @machelreid - without you this would not have happened!
