Snapchat’s creator has a new version of its glasses, and a vision for more approachable augmented reality. But it’s still a preview, not a commercial product.

Bailenson and other Stanford researchers tested out the Meta Quest 3, a “mixed reality” headset that lets people blend physical and virtual worlds. While the headset is different from AR glasses, the gadget can display real-time video of a user’s surroundings in the physical world.

The AR glasses aren’t available to the general public, but that hasn’t stopped criticism over the gadget’s limited battery life and field of view.
