We present a formal representation which can be used in the specification of role related re- quirements for interaction between be- tween artificial agents, and for the spec- ification of human-computer interfaces.

Argumentation theory has tradi- tionally been used to deal with conflicts between defaults and beliefs. Recently Amgoud has proposed to use it for conflicts between plans. Amgoud argues that Dung's argumentation theory has to be adjusted, because conflicts between plans are fundamentally different from conflicts between defaults. We

The virtual theatre allows navigation through keyboard and mouse, but there is also a navigation agent which listens to typed in- put and spoken commands. We also have an information agent which allows a NL dialogue,
