The idea of this concept was to exploit the internet ability in a mobile device. Touch screen, built in camera, scanner, WiFi, google map (hopefully google earth), google search, image search? all in one device. See a building through it, it will give you the image search result right on the spot.
Choose a building and touch a floor and it tells you more details of the building. You can use it when you want to know a car model, an insect name, what kind of food is served at a restaurant and how much, who built a bridge, etc. With detail informations like that, this gadget might only be used by secret service agents. Very futuristic concept.
