Vuzix SMART Augmented Reality Glasses
Although shown at conferences–by a man who keeps referring to the product as “these guys here”–since last January, the Vuzix SMART AR glasses won't be available for purchase until 2013. The waveguide display most likely only overlays the image at one depth in a vertical plane in front of the viewer; it won't be mapping over reality at a distance very cleanly. But they're better than nothing, I suppose.
I still can't quite wrap my head around (or within) the idea of these “cheap” AR experiences making a big impact into consumer markets. But for commercial applications, inexpensive HUDs could be useful. In fact, Vuzix says they're working on monocular models for U.S. military application.
