The video is called "Field Trip" and shows off some of the features of Google's Field Trip app. It's a short, but extremely compelling video that shows how mobile can be used to personalize your world - whether it is a wander about the bay area (this video) or your childhood home. You can consume someone else's story or tell your own story. Not to be creepy and it isn't Halloween, but what if you could use augmented reality - digital overlay of content triggered by location or recognizing an object/symbol - of grave stones? Visiting a cemetary could be SO cool. Visting your apparel shop, grocery store, airport lounge, restaurant, bank branch, healthcare clinic could also be cool IF you use your imagination.
Google's Ingress game layers both content and a game onto the physical world. (watch the video)
What's in it for the eBusiness professional?
I'm not necessarily suggesting a scavenger hunt in your store. Ingress + Hint Water did pull this off - not a hunt, but what is a game that combines digital with the physical world as a game board? I remember when Starbucks ran a scavenger hunt that started with a SMS-based trivia game more than five years ago. It was a huge hit.
