Are Augmented Reality Projectors Dead?

There was a time that augmented reality projectors like the Sixth Sense video or the one I’ve posted below from a year ago were hot news.  I haven’t heard a peep about them in quite a long time.  Is this a sign that developers have weighed the options and smartphones and glasses have won out?  Or are there still people out there working hard, but just not tooting their own horns?  If you’ve seen any recent news about projector technology in regards to augmented reality, I’d love to hear about it.
