Kevin: Benji Lanyado, travel journalist and one of the journalistic innovators here at the Guardian, answers some of the questions that I posed in a post on the Guardian's digital content blog about augmented reality – applications that layer information over the physical environment that you're in. IBM is getting a lot of attention for its Wimbledon AR application, the Wimbledon Seer, which layers over match and venue information over the camera view from a Google Android phone. Very clever. Benji and I have talked about the possible applications for AR in travel. He expands on his ideas on his new blog. Worth a read.
