Most solutions are based on Kopin display components which are really screens for handycam viewfinders.&lt;p&gt;Vuzix is doing something really interesting with transparent displays using waveguide technology (&lt;a href=&quot;http://www.engadget.com/2012/01/12/vuzix-augmented-reality-smart-glasses-prototype-hands-on-video/&quot; rel=&quot;nofollow&quot;&gt;http://www.engadget.com/2012/01/12/vuzix-augmented-reality-s...&lt;/a&gt;). This, to me, is the future of HUD glasses. A solution with a screen blocking one eye, as it seems Google is doing - I can&apos;t see that working out, unless they are sitting on some breakthrough display technology.</text><parent_chain><item><author>pshc</author><text>Not saying this is what they&apos;re selling, but: Real-time overlays are still impractical, right? My intuition is--without a really high speed camera and high fidelity environmental cues--the overlay will have a lag and high uncertainty wrt where you&apos;re actually looking... or has the state of the art moved on? Or are their labs advancing the state of the art?&lt;p&gt;Any idea how they&apos;re making the screen usable at that focal length? Don&apos;t VR headsets usually need optics much more bulky than sunglasses for comfortable viewing?&lt;p&gt;Anyway, even if it&apos;s smartphone-like functionality in a more convenient form factor, I&apos;m looking forward to being an early adopter.</text></item></parent_chain></comment><story><title>Google to Sell Heads-Up Display Glasses by Year’s End</title><url>http://bits.blogs.nytimes.com/2012/02/21/google-to-sell-terminator-style-glasses-by-years-end/</url></story>
