AR stereoscopic see-through displays are complex, difficult tech. This has nothing to do with Google Glass which is closer to being an aside information display.
Sony has the most IPR and expertise in the field when it comes to displays that create a 3D augmented experience for both eyes. They have examined this field for ages and had a hard time to discover application fields.
Meta hopefully cracks this nut and delivers a development program that brings stereoscopic AR to the next level. But as someone who managed an AR portable display team in this field for VF, I see it as a steep challenge.
Glad to see someone else here has seen Dennou Coil - IMO it should be required viewing for anyone interested in AR! It's not perfect, but has some fascinating ideas about where AR could go.
