Location-aware technology is a general term for technology that can determine its own geographical location. A familiar example is the Global Positioning System (GPS) — the navigation system that is installed in many cars today. A GPS uses satellites to triangulate its position on the surface of the Earth. It then displays this psition on a map. Value is added when physical information is combined with the descriptions about that location (e.g. street layouts, local landmarks, directions to a destination, etc.). Related terms include “georeferencing†and “geotagging,†which refer to specifying the geographic location associated with some piece of information. An example of this would be relating key events in history to points on a map, thus enabling a new way to navigate the content and discover relationships within it. One of the things we are looking at how location aware mobile devices can be used to update learning opportunities on the fly.
