Lisa Barone tells us about augmented reality, a technology that merges a real-world environment with computer generated imagery. Think "digital layer on top of the real world," she writes. (That's an accurate description, actually.)
Barone points to mobile browsers that layer the data and allow people to interact with the elements on a mobile phone. Her rough blogging is difficult to get through, but the concepts are clear and the information enlightening. Brands using augmented reality for marketing include Esquire, Star Trek, General Electronic, and USPS.
