At the MetaConnect event in California on September 25, Zuckerberg showcased Orion for the first time, which uses a tiny projector built into the eyeglass arm to create a head-up display that appears as if it were on a real-world object. "Right now, I think the right way to look at Orion is as a time machine," Mr. Zuckerberg said, holding up the new AR glasses. He added: "These glasses do exist, they're great and they give us an exciting look into the future." Orion can be controlled by voice prompts, but the device, which Zuckerberg calls a "neural interface", can also be controlled by a device that can be worn on the wrist. Orion users can make specific gestures to navigate and control apps on the smart glasses while wearing the wristband.
