Augmented Maps
July 23rd, 2005

Printed maps are easy to manipulate, provide an easy way of interacting for multiple users, but are static and can be out of date. On the contrary, computer-based map displays can provide dynamic and more recent information than paper-based maps, but do not help a group of people to communicate.

So why not mix them? This is what have done researchers at England’s University of Cambridge with their augmented maps, which add digital graphical information and user interface components to printed maps. Here is how this works: the printed maps are placed on a flat surface; an overhead camera linked to a PC tracks the map via the live video stream; and an overhead projector adds graphical information to the maps.

This could be useful for many applications, and the researchers have applied it to a flood simulation of the Cambridge area. Read more for selected details, references and pictures.
