Vicarious Learning and Multimodal Dialogue

Vicarious Learning is learning from watching others learn. We believe that this is a powerful model for computer-based learning. Learning episodes can be captured and replayed to later learners: this depends on the learning content being accessible and as far as possible external. A natural context for this is learning embedded in dialogue, and especially multimodal dialogue involving diagrams and gesture. This paper discusses work in progress in two projects addressing aspects of these issues.
