dirty looks, though it's far from alone. At this year's DroidCon in London, I talked with Epson Europe product manager Marc-Antoine Godfroid about a very different kind of head-worn display: the Moverio BT-100. Epson's display is running a Google operating system, but it isn't competing with Glass, at least not directly. The hardware in this case is a relatively high-definition stereo display meant for immersion (whether that means information overlays or watching recorded video) hooked to an external control unit running Android, rather than the sparer, information-dashboard, all-in-one approach of Glass. One other big difference: Epson's stereo, full-color headset is cheaper than Glass, and available now. Hit the link below to see what it looks like.
