Abstract

We present an empirical investigation of nonverbal behavior in long-term interaction spanning multiple conversations, in the context of a developing interpersonal relationship. Based on a longitudinal video corpus of human-human counseling conversation, we develop a model of the occurrence of posture shifts which incorporates changes that occur both within a single conversation and over multiple conversations. Implications for the design and implementation of virtual agents are discussed, with a particular focus on agents designed for long-term interaction.
