Abstract

USC researchers are involved in a project called the Mission Rehearsal Exercize (MRE) which has to do with extending the capabilities of virtual humans, defined as autonomous agents that accommodate face-to-face interaction in various roles. The research is expected to have applications in entertainment and in training for the military.

Abstract

NPCEditor is a system for building a natural language-processing component for virtual humans capable of engaging a user in spoken dialog on a limited domain. It uses statistical language-classification technology for mapping from a user's text input to system responses. NPCEditor provides a user-friendly editor for creating effective virtual humans quickly. It has been deployed as a part of various virtual human systems in several applications., Virtual Humans Imagine talking to a computer system that looks and acts almost human--it converses, understands, can reason, and can exhibit emotion. As an example, recall such computer characters created [...]

Abstract

This article describes the virtual humans developed as part of the Mission Rehearsal Exercise project, a virtual reality-based training system. This project is an ambitious exercise in integration, both in the sense of integrating technology with entertainment industry content, but also in that we have joined a number of component technologies that have not been integrated before. This integration has not only raised new research issues, but it has also suggested some new approaches to difficult problems. We describe the key capabilities of the virtual humans, including task representation and reasoning, natural language dialogue, and emotion reasoning, and show how these capabilities are integrated to provide more human-level intelligence than would otherwise be possible., Achieving human-level intelligence in cognitive systems requires a number of core capabilities, including planning, belief representation, communication ability, emotional reasoning, and most importantly, a way to integrate these capabilities. And [...]

Abstract

We present a fully automated workflow for phylogenetic reconstruction on large datasets, consisting of two novel methods, one for fast detection of cognates and one for fast Bayesian phylogenetic inference. Our results show that the methods take less than a few minutes to process language families that have so far required large amounts of time and computational power. Moreover, the cognates and the trees inferred from the method are quite close, both to gold standard cognate judgments and to expert language family trees. Given its speed and ease of application, our framework is specifically useful for the exploration of very large datasets in historical linguistics.

Abstract

The Equilibrium Theory put forward by Argyle and Dean, posits that in human-human interactions, gaze and proxemic behaviors work together in establishing and maintaining a particular level of intimacy. This theory has been evaluated and used in Virtual Reality settings where people interact with Virtual Humans. In this study we disentangle the single and joint effects of proxemic and gaze behavior in this setting further, and examine how these behaviors affect the perceived personality of the agents. We simulate a social encounter with Virtual Humans in immersive Virtual Reality. Gaze and proxemic behaviors of the agents are manipulated dynamically while the participants’ gaze and proxemic responses are being measured. As could be expected, participants showed strongest gaze and proxemic responses when agents manipulated both at the same time. However, agents that only manipulated gaze elicited weaker responses compared to agents that only manipulated proxemics. Agents that exhibited more directed gaze and reduced interpersonal distance were attributed higher scores on intimacy related items than agents that exhibited averted gaze and increased interpersonal distance.

Abstract

We present a demonstration system for incremental spoken human–machine dialogue for task-centric domains that includes a controller for verbal and nonverbal behavior for virtual agents. The dialogue management components can handle uncertainty in input and resolve it interactively with high responsivity, and state tracking is aware of momentary events such as interruptions by the user. Aside from adaptable dialogue strategies, such as for grounding, the system includes a multimodal floor management controller that attempts to limit the influence of idiosyncratic dialogue behavior on the part of our primary user groups – older adults and people with cognitive impairments – both of which have previously participated in pilot studies using the platform.

142. This Is What’s Important – Using Speech and Gesture to Create Focus in Multimodal Utterance

Abstract

In natural communication, humans enrich their utterances with pragmatic information indicating, e.g., what is important to them or what they are not certain about. We investigate whether and how virtual humans (VH) can employ this kind of meta-communication. In an empirical study we have identified three modifying functions that humans produce and perceive in multimodal utterance, one being to create or attenuate focus. In this paper we test whether such modifying functions are also observed in speech and/or gesture of a VH, and whether this changes the perception of a VH overall. Results suggest that, although the VH’s behaviour is judged rather neutral overall, focusing is distinctively recognised, leads to better recall, and affects perceived competence. These effects are strongest if focus is created jointly by speech and gesture.

143. Ithe effect of an intelligent virtual agent’s nonverbal behavior with regard to dominance and cooperativity

Abstract

In order to design a successful human-agent-interaction, knowledge about the effects of a virtual agent’s behavior is important. Therefore, the presented study aims to investigate the effect of different nonverbal behavior on the agent’s person perception with a focus on dominance and cooperativity. An online study with 190 participants was conducted to evaluate the effect of different nonverbal behaviors. 23 nonverbal behaviors of four different experimental conditions (dominant, submissive, cooperative and non-cooperative behavior) were compared. Results emphasize that, indeed, nonverbal behavior is powerful to affect users’ person perception. Data analyses reveal symbolic gestures such as crossing the arms, stemming the hands on the hip or touching one’s neck to most effectively influence dominance perception. Regarding perceived cooperativity expressivity has the most pronounced effect.
