Google has at least three AR products: Glass is still in business for enterprise, Tango tablets and phones are finally out, and future versions of Daydream are supposed to be capable of inside-out tracking via an AR tracking system.

Microsoft has the HoloLens, which technology they have also cannibalized for a series of headsets they are dubbing "Mixed Reality" for the depth camera pass-through they are performing.

HTC is supposedly developing their own AR/inside-out system.

Leap Motion, Intel, Qualcomm, Meta, and Magic Leap are still considered in the running, with varying levels of believability.

And then there are a slew of different companies that are doing AR solutions with either the standard webcam (e.g. Facebook, Snap, Vuforia, Wikitude) or their own, standalone camera (e.g. Zed, Occipital).
