04121 Working Group 2 – Design criteria, techniques and case studies for creating and evaluating interactive experiences for virtual humans

Abstract
How does one go about designing a human? With the rise in recent years of virtual humans this is no longer purely a philosophical question. Virtual humans are intelligent agents with a body, often a human-like graphical body, that interact verbally and non-verbally with human users on a variety of tasks and applications. Our working group approached this question from the perspective of interactivity. Specifically, how can one design effective interactive experiences involving a virtual human, and what constraints does this goal place on the form and function of an embodied conversational agent. Our group grappled with several related questions: What ideals should designers aspire to, what sources of theory and data will best lead to this goal and what methodologies can inform and validate the design process? A longer article (.pdf) summarizes the output of this WG and suggests a specific framework, borrowed from interactive media design, as a vehicle for advancing the state of interactive experiences with virtual humans.

ECA Perspectives - Requirements, Applications, Technology

Authors: Anton Eliens, Zhisheng Huang, Johan F. Hoorn, and Cees T. Visser

Published in: Dagstuhl Seminar Proceedings, Volume 4121, Evaluating Embodied Conversational Agents (2006)

Abstract
In the last years we have developed a platform for the realization of embodied (conversational) agents, in a distributed logic programming framework. In this paper we will present an overview of our work, by discussing the requirements that acted as our guidelines for design decisions during development, some of the applications that have served as target demonstrators for developing and testing new functionality, and the (distributed logic programming) technology which we used for the realization of the platform and the implementation of our STEP scripting language. Although the focus of our paper will primarily be our own DLP+X3D platform, we believe that our discussion along the perspectives of requirements, applications and technology might be more generally worthwhile in establishing the relative merits of the operational use of ECA-technology. At the end of this paper, we will moreover provide some hints of how to approach the experimental validation of the (possible) benefits of embodied conversational agents in user applications.
