“The G1 phone has a built-in compass, which means that it can not only determine where users are, but also which direction they’re facing. Which gets interesting when combined with the phone’s camera, which is what the Dutch bank’s new tool does.”
this is what the ING bank doing on G-phone, when you take a photo, they will indicate where’s the nearest ATM on your photo, isn’t it cool?
To apply it on a travel guide, this could be a highly interactive travel book.
I think this feature is cool!
