This paper discusses GAIA (Graphic-Audio Interface Agent), an experimental interface agent used in a pedagogical simulation program, REM(the Re-mapping Europa Mission), where the learning task is the discrimination of specific locations on a series of unlabelled maps. The agent's task is to enhance the learning experience by providing timely, contextual clues mediated through a graphic/audio interface. Factors that influence such an agent's ability to provide effective help, such as modes of agent representation, are discussed in the context of differing uses requiring alternative mode choices. The experimental context is explored with an in-depth look at the REM program. The paper concludes with comments on audio interfaces, suggestions for multimodal agent design and likely future directions for multimodal agent interfaces.
