By nature, they are dense and rich in objects and information, and as a result they contain more information than a visitor can absorb in a time-limited visit. Many research projects have explored the potential of novel technologies to support information delivery… (More)
In this paper we describe the in-progress work of the Pathlight navigation system for groups and individuals. Pathlight provides indoor navigation support in the museum using a handheld projector. We describe some of the advantages the system provides, look at some background, briefly describe some system features, and posit some open questions for further… (More)
