PDF: Believability and Co-presence in Human-Virtual Character Interaction

Abstract

Subtle phenomena rooted in our body dynamics affect the reactive and evolutive parts of every human interaction. The authors’ decision model allows for adaptive physical interactions between a human and a virtual agent. This article presents an evaluation of that model in terms of agent believability, the user’s feeling of co-presence, and overall game experience. The results show that the model can generate adaptive body behavior for virtual agents that is comparable to a human’s, but the user and agent roles in each scenario strongly impact the user’s perception of the agent.
