Abstract

Agency and hypermedia have both been suggested as powerful means to cope with future information management and human-computer interaction requirements. However, research projects have included interface agents only marginally in the context of hypermedia systems. This article proposes a set of criteria for characterizing interface agents and offers a perspective view of ongoing research in the field using those criteria as a framework. The need to provide a supporting infrastructure that facilitates testing and experimentation of interface agents is stressed. The article describes an existing open hypermedia architecture and introduces an extended architecture that includes provisions to support the development and operation of interface agents. A prototype instantiating this system architecture is presented, as well as an initial assessment of the potential and requirements of interface agents in a hypermedia environment.
