Video is from Nokia’s research arm. Voice recognition has much more to do with the actual phone running the software. AR glasses could easily include microphones for voice recognition. They probably wanted to show the new AR display technology and what you can do with it.

Vuzix did show protos of EPE based devices in CES. One was monocle device intended for tactical and indrustial market. They said it could be out this year in 3rd quarter. price tag 2500-5000$, which is fully expected for anything with “tactical” in it.

Also they had “smart glasses” prototype device, which was basicly a more refined and realistic version of those glasses in nokias concept video. They said consumer devices will become available in 2013-2014. Price target 350-600 $.There is lots of youtube videos about these, just search vuzix smart glasses.

From what i gather google has only concept video of a very concept stage device. While vuzix and nokia have working technology and consumer ready prototypes. So unless google manages to do a miracle Vuzix will be first in market. Actually google stuff seems lot like LUMUS OE-31, so if google has actual working prototype that’s probably what they are using in it.

Vuzix has years of experience in AR and HMD production and design. From what i heard in the videos Vuzix idea is to place only sensors and displays on the glasses and let a smart phone do all calculation. Which  very good idea, because you want to keep the head gear as light as possible. Place displays, couple cameras, gps reveicer and tracker in glasses. Cpu, gpu, storage and radios should be in the phone. That way all heat and massive battery packs are away from your head. Unless somebody comes up with bluetooth for 720p video, you have to tether with hdmi anyway. HDMI or other normal display connector also quarantees interoperatibility between different devices. I don’t want to buy 500$ AR displays, which work only with one specific phone.

Plus this is just a personal opinion, but pair of regular looking oakley’s is much better idea for your product design. That google monocle looks like somebody was told to make a AR-display and the first thing he could think of was scifi-movies. Seriously, thats the most ankward looking headset a have seen. Why do they have that headband, when it is a monocle? It looks like somebody forgot to put lenses in their eyeglasses.

Still I’m happy, that google is doing this. It puts pressure on Nokia and Vuzix.
