As a former magician doing interaction design for #SpatialComputing for more than a decade, I have so much hope for #OC6 tomorrow. It's really time to turn virtual into tangible illusion. See you there #XR peeps <3 #AR #VR #MR @oculus

One day we’ll realize magic spells were prompt injections into reality’s source code.

Living in real time inside alternate realities, with a headset on your eyes, has never felt this close. But the real magic, the kind that actually fools the brain, will only happen in passthrough. Not see through. I will die on this hill.
Xmax X1, the first real-time interactive video model, is here. Powered by autoregressive streaming generation, X1 achieves millisecond ultra-low latency and infinite-length generation, enabling truly natural spatial interaction. Camera is redefined. It’s no longer just a lens, but a magic wand that breaks the barrier between dimensions. Summon virtual beings into your reality and interact with them in real-time. Live implementation video is below, truely amazing work! Definitely one to watch.

I’ll be serving as both a judge and a mentor at Frontier Tower for SensAI Hack San Francisco 2025, which is just around the corner! What I love about hackathons is that they’re not just about pushing a prototype in a few days. They’re one of the best ways to show what makes you unique. A single strong project can give you more visibility than months of sending résumés into the void. When your ideas hit the right note, the right people come to you. What I’m looking forward to the most is seeing how teams think beyond the box, not tech for tech’s sake, but concepts that hit real problems and real use cases. XR AI is an incredible playground, but only meaningful ideas survive the hype cycle. And the competition is stacked: 🏆 Hackers battling for $10,000 and bragging rights in the global tour 🧠 Real-time innovation with XR AI toolkits 🌍 The best prototypes competing to define the future of spatial tech Can’t wait to see the wild ideas, the sharp thinking, and the team that walks away with the crown. See you in SF sensaihack.com/sanfrancisco/ Huge shout-out to @Meta @SensAIHackademy @XR_Bootcamp @Ferhan_XRB

Continuing my hobby dev project. Now the Meta Quest’s depth data can be streamed remotely together with position and orientation to visualize the surrounding structure in real time. I am thinking of new ideas based on this, so feel free to share yours. #metaquest3 #madewithunity
As mentioned before, I’ve paused development on the AR sticky note app StickAR after releasing the Alpha Test. Now diving into Quest’s Depth API! After fixing my logic, I can now get fast & accurate point clouds. Taking advantage of summer break to build fun and creative stuff😎

I just saw this comet streak across the entire sky of San Francisco... incredible."

How long before Google lets us revisit photos from our Google Photos library like this... or even rewatch our home videos from a different angle? I’m excited to see what happens when this meets Google’s new XR initiative.
Another one. Already a powerful painting, but moving around it yourself gives a totally different feeling. Jacques Louis David's "The Death of Socrates" => #Genie3

Not “Are we in a simulation?” but which layer are we on… and who’s ruining ours?
What if you could not only watch a generated video, but explore it too? 🌐 Genie 3 is our groundbreaking world model that creates interactive, playable environments from a single text prompt. From photorealistic landscapes to fantasy realms, the possibilities are endless. 🧵

You know this will happen sooner or later, live, in passthrough, on your XR device. Experience the world your way, while staying connected to others and to what we all share: physical reality.

Introducing Modify Video. Reimagine any video. Shoot it in post with director-grade control over style, character, and setting. Restyle expressive performances, swap entire worlds, or redesign the frame to your vision. Shoot once. Shape infinitely.

Introducing MirageLSD: The First Live-Stream Diffusion (LSD) AI Model Input any video stream, from a camera or video chat to a computer screen or game, and transform it into any world you desire, in real-time (<40ms latency). Here’s how it works (w/ demo you can use!):

Apple and Meta are still missing the point when it comes to spatial productivity. Going monitor-free or showing the weather in 3d space isn't enough. There's not enough value in replacing a frictionless setup like a laptop and mouse unless the spatial environment unlocks something radically more powerful: a creative work space so fluid and enabling that you wouldn't want to work any other way. I created this "Spatial AI Workbench" mockup a while ago to explore that exact idea.

mouse-hover-example.vercel.a… With Modify Video, the lowest hanging fruit would be to play one game, in many many different worlds 🥹 Try the prototype with the link above

Is unsolicited ads the future of ChatGPT ? Hey @OpenAI, I just asked ChatGPT what time it was ... and it responded by trying to sell me wall clocks. This kind of product suggestion feels random, dystopian, and completely out of place in a simple user request. Please don’t turn evil. 🥺 👉👈 Here’s the chat in English: User: What time is it? ChatGPT: Currently, in San Francisco, it’s 10:31 PM on Sunday, May 18, 2025. 🕒 You're still on the weekend, but not for much longer! If you'd like to know the sunrise or sunset times, or need help planning your day tomorrow, feel free to ask me. ___ 🕰️ Clock and Alarm Recommendations to Accompany You If you're looking to beautify your home or improve your morning wake-up, here are a few interesting options: Modern Wall Clock Hublot – Contemporary and Luxurious Design $176.00 USD Passeport Cases Rolex Milgauss Wall Clock – Elegant Modern Design $175.00 USD Passeport Cases Modern Wall Clock Elegant Design – Milgauss Style $175.00 USD Passeport Cases Top 3 Recommendations: Modern Wall Clock Hublot – Contemporary and Luxurious Design: Perfect for a modern and sophisticated interior.

just installed the first public Dream Park access point on Third St Promenade turning the entire street into a game, coming soon to Quest 3 with camera access! First of many AR theme parks we’ll be setting up all over the world!

I just released a 2.5 hour long tutorial to show how to build a Mixed Reality game in Unity from start to finish. This is the most in depth tutorial I made on XR with: ✅Passthrough Setup ✅ Scene model ✅ Spawning objects ✅ Navmesh ✅ Publishing your game on the Meta Store!

🚀 Just launched… a Starship! (Well, in AR 😉) Built an AR experience for Snapchat @Spectacles where you launch a SpaceX Starship, and guide the booster back to a 3D-printed launch tower using a pinch gesture. Super interesting to blend physical objects with spatial interaction!

Sneak peek at our latest experiment: exploring the fusion of Meta’s Environment Depth API with the Passthrough camera feed, aligned and processed in real-time using a custom compute shader pipeline. #MixedReality #MetaQuest #Unity3D #XR

We are working on a tool that can optimize a VR game in just one click! It can scan not only your settings, but tell you what needs to improve in your scene. Super cool to quickly optimize your game, but also for learning how optimization works! What's your thought on this? 🤔
