Alternative styles for human-computer interaction and human-human computer-mediated communication are needed to assist users in dealing with the ever-growing and complex information spaces at their disposal. PARAgente is a comprehensive research initiative aimed at investigating the issues, requirements and potential of interfaces which are based on user agents. This paper discusses major issues that must be addressed if agents are to become accepted by users in their interaction with computer systems. A testbed designed to explore these issues in the context of an open hypermedia system is also presented.
