We present a model of negotiation for virtual agents that extends previous work to be more human-like and applicable to a broader range of situations, including more than two negotiators with different goals, and negotiating over multiple options. The agents can dynamically change their negotiating strategies based on the current values of several(More)
While virtual humans are proven tools for training, education and research , they are far from realizing their full potential. Advances are needed in individual capabilities, such as character animation and speech synthesis, but perhaps more importantly, fundamental questions remain as to how best to integrate these capabilities into a single framework that(More)
When dealing with large, distributed systems that use state-of-the-art components, individual components are usually developed in parallel. As development continues, the decoupling invariably leads to a mismatch between how these components internally represent concepts and how they communicate these representations to other components: representations can(More)
Posttraumatic stress disorder (PTSD) is a chronic, debilitating, psychological condition that occurs in a subset of individuals who experience or witness life-threatening traumatic events. PTSD is highly prevalent in those who served in the military. In this paper, we present the underlying theoretical foundations and existing research on virtual reality(More)
We present SimSensei Kiosk, an implemented virtual human interviewer designed to create an engaging face-to-face interaction where the user feels comfortable talking and sharing information. SimSensei Kiosk is also designed to create in-teractional situations favorable to the automatic assessment of distress indicators, defined as verbal and nonverbal(More)
Tutorial Objectives Virtual humans (VHs) are digital anthropomorphic characters that exist within virtual worlds but are designed to perceive , understand and interact with real-world humans. Although typically conceived as practical tools to assist in a range of application (e.g., HCI, training and entertainment), the technology is gaining interest as a(More)
Blendshape interpolation is one of the most successful techniques for creating emotive digital characters for entertainment and simulation purposes. The quest for ever more realistic digital characters has pushed for higher resolution blendshapes. Many existing correspondence techniques, however, have difficulty establishing correspondences between very(More)
—We present the SimSensei system, a fully automatic virtual agent that conducts interviews to assess indicators of psychological distress. With this demo, we focus our attention on the perception part of the system, a multimodal framework which captures and analyzes user state behavior for both behavioral understanding and interactional purposes. We will(More)
