This is the type of technology that is crying out for a killerapp, but may end up struggling to find one.
I had a Vodafone R&D team working with the Sony 3D AR glasses (aka 'Tom Hanks CES glasses'). We loved the tech and had a great playground, but couldn't get to the creation of one app that solved a clear painpoint.
We ended up with glorious tech demos, but they were all suited for a short-lived themepark attraction but not for ongoing use.
Anyway, I am excitedly waiting for someone who can do better than us.
