The Use of Maps, Images and "Gestures" for Navigation

The problem of designing an information system for locating objects in space is discussed. Using the framework of a cognitive collage, as developed by Tversky (1993), it is argued that redundant information from a variety of media is most useful in constructing a spatial information broker. This approach is supported by examining four case studies in detail, you-are-here maps, information kiosks, an information browser, and library locator system. Implications for design of future navigation systems are discussed.
