Integrating pedagogical capabilities in a virtual environment agent (original) (raw)

1997, Proceedings of the first international conference on Autonomous agents - AGENTS '97

Virtual environments are a promising milieu for education and training, because they allow students to practice their skills in 3D simulations of work settings. Autonomous agents can improve the e ectiveness of such e n vironments by assisting and collaborating with students as appropriate. This paper describes an autonomous pedagogical agent called Steve that can support the training of procedural skills such as operating or repairing complex equipment. Steve's architecture permits him to sense and manipulate dynamic virtual worlds. The architecture also enables Steve to assume alternative realizations, either as a full, articulated, human gure or as abstract pointers and disembodied hands. Steve employs a combination of intelligent capabilities in his interactions with students and the environment: plan revision and execution, explanation, and student monitoring. These capabilities are employed in multiple ways in order to support alternative pedagogical styles. Steve's knowledge representation is designed so that agent capabilities can be authored without detailed knowledge of agent architectures and languages.
