Google Glass video preview : previously unrevealed functionality
You can also ask the device to translate phases into other languages, and it will speak back to you the translated words—a feature not previously demoed by Google. Another previously unseen (yet widely expected) feature spotted in the video is Google Now integration. In an example of a couple at the airport, a man sees his terminal, gate, and departure information in the corner of his Google Glass display. The video also hints that you will be able to use Google Glass to get Google Maps-powered navigation directions in traffic, on the ski slopes, and elsewhere.
The hardware powering the Glass display itself is perched just above your ordinary field of view, like at the top of the frame of sunglasses.
Google released the video to herald a new wave of pre-order openings for the $1,500 gadget. Only a limited set of developers and pundits have been able to try them out up to this point, but now, Google is running a contest that opens pre-orders to “bold, creative individuals” who impress Google-ites with their plans for the eyewear. You’ll need to share your ambitions on Google+ or Twitter using the #ifihadglass hashtag, and yes, you still need to lay down $1,500 for the device if you’re picked.
