An AR (Augmented Reality) headset is defined as a wearable where the user can see through it (unlike a VR headset) to the outside world, and it adds new visual information on top of what the viewer sees. It’s not sufficient to have glasses that have functionality like taking pictures, or that modify the visual field with filters. The new visual information must be in some way based on what the user is doing or seeing. Microsoft Hololens would qualify, but is already extant. Must be released by one of Meta, Google, Apple, Amazon specifically, and must be available for purchase by the public in some capacity.
