Appropriate perception and expression of dominance (verticality) is essential for social interaction. In this paper, we present our work on algorithmic modulation of robot bodily movement to control dominance expression. We developed a parameter-based model for body expansiveness. This model was applied to a variety of behaviours and evaluated by human observers in two different studies with respectively static postures (N=772) and gestures (N=31). Modulation of body expansiveness proved to robustly influence perceived dominance independent of behaviour and viewing angles.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115078516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This ability should be emulated by social agents. How fast interruptions are handled might influence the overall impression of an agent. In this paper, we present the results of a user study on how a human dialog partner perceives the be- havior of a virtual agent handling verbal user interruptions with different reaction times. The study goes beyond typical perception experiments by preserving the real-time interaction experience. For the evaluation, we rely on a parametrizable parallelized computa- tional model that represents dialog flow, overlap detection, conflict recognition, and conflict handling in real-time. The evaluation re- sults show that the timing of the agent's interruption handling in interactive human-agent dialogues is related to different interper- sonal attitudes.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"349 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114742115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present an interactive system in which a virtual agent adopts a dynamic communication strategy during the interaction with a user, aiming at forming and maintaining a positive impression of warmth and competence. The agent continuously analyzes user's non-verbal signals to determine user's engagement level and adapts its communication strategy accordingly.

Virtual agents have been shown to be effective communication skills training coaches and effective as virtual audiences for inducing anxiety in public speaking exposure therapy. To date, there are fewer research interventions, including virtual agents, that are designed to assist presenters manage their anxiety in real-time during presentations. Our research attempts to fill this gap by exploring ways in which technologies, including virtual agents, can help reduce anxiety during presentations. To help presenters manage their anxiety, we will design and evaluate an automated real-time framework for detecting public speaking anxiety and explore behavioral just-in-time techniques that presenters can use while presenting. Our automated framework will be guided by a physiological detection model, use a virtual agent as the user interface, and will assist presenters during their presentation.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126123202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its spontaneous reactive behaviors are trained from a multimodal data corpus collected in a human-human conversation experiment. Two Gated Recurrent Unit (GRU) based models are switched when the agent is speaking or is not speaking. These models generate the agent's facial expressions, head movements, and postures from the corresponding behaviors of the human user in real-time. Benefits from the flexible design, the utterance generation part can be an autonomous dialogue manager with hand crafted rules, an on-line chatbot engine, or a human operator.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129010795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effective use of such environments requires the ability to generate consistent scenarios, which involve one or more realistic yet repeatable interactions between the trainee and the virtual humans in the training environment. This paper presents a framework that facilitates the development of rich interactive scenarios between one or more virtual humans and a trainee. The framework utilizes a scenario authoring system with runtime elements that ensure the trainee encounters realistic and stochastic, yet repeatable, well-orchestrated and precisely choreographed situations to meet specific training goals. Core elements of the framework include the use of probabilistic state machines for controlling the behavior of virtual elements along with triggers which ensure pre-determined outcomes even when utilizing stochastic behavioral models for the virtual humans.","PeriodicalId":112642,"journal":{"name":"Proceedings of the 19th ACM International Conference on Intelligent Virtual Agents","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125728917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
