Geo-location services = services that allow you to know where you are physically, and eventually to call up virtual information on certain objects in that location.

Examples

Cellphone-based geo-location services

"If you stand on a street corner in Tokyo today you can point a specialized cellphone at a hotel, a restaurant or a historical monument, and with the press of a button the phone will display information from the Internet describing the object you are looking at.

The new service is made possible by the efforts of three Japanese companies and GeoVector, a small American technology firm, and it represents a missing link between cyberspace and the physical world.

The phones combine satellite-based navigation, precise to within 30 feet or less, with an electronic compass to provide a new dimension of orientation. Connect the device to the Internet and it is possible to overlay the point-and-click simplicity of a computer screen on top of the real world."
