Personalized explanations by virtual characters.

PhD research topic

Objectives:

To define, implement and evaluate communicative strategies for the generation of interactive, personalized explanations by embodied conversational agents.

As a starting point this ESR takes the alignment mechanism that occurs in conversation between humans: the tendency to copy various aspects of each other’s language such as syntactic structure and word choice, and to mirror each other’s non-verbal behaviour. We will investigate whether using alignment to tailor the way explanations are presented to the user by embodied conversational agents, will improve comprehensibility and persuasiveness of the explanations.

Use case:

The main use case will be the generation of explanations by virtual coaches in the e-health domain, building on the work in the currently running H2020 project Council of Coaches in which UTWENTE participates.

Expected Results:

– Design of alignment-based, personalized explanation strategies for embodied conversational agents, based on studies of alignment in human communication.

– Implementation of these strategies in one or more embodied conversational agents functioning as virtual health coaches.

– Evaluation of the effects of personalized explanation strategies on comprehensibility and persuasiveness, based on human-agent interaction experiments in the e-health domain.

– Small-scale implementation and evaluation of the above in the context of a secondary use-case to be developed in the inter-sectoral secondment in accordance with the stakeholder.
