Integrated characters with dialogue and tutorial strategies

In this deliverable, we introduce three new virtual character support types (Critic, Quiz and Diagnosis) which are linked to different kinds of conceptual knowledge (such as semantic feedback or multiple choice questions) generated within the DynaLearn software. We show how this knowledge is extracted and transformed into character-specific dialogs that are presented by the virtual characters but also encourage the learner to engage and participate. For this process, we rely on the architecture and dialog management system developed in earlier deliverables. Finally, we investigate how different characters and support types can be combined with each other to from integrated dialogs to even further support and engage learners
