reminds me of a much more practical version of some of the cool bits from the "sixth sense" interface that was presented at TED / all over the news awhile ago - http://www.pranavmistry.com/projects/sixthsense/ . There, their prototype was also able to "look at" an object and return information about it immediately (e.g. you hold up a book in front of the camera, a processor recognizes it and pulls some relevant information, and the mini projector next to the camera projects the information back onto the book cover)
