Title: Using Virtual Humans as Entourage Elements in Architectural Walkthroughs The well-known problem of egocentric distance underestimation in VR has
particular implications for architectural applications, in which
designers and their clients seek to use VR to obtain a first-hand
appreciation of the aesthetic and practical suitability of designed
spaces. Recent research in our lab and elsewhere has suggested that
first-person self-embodiment in HMD-based immersive virtual environments
may facilitate more accurate distance (and size) judgments, but the
underlying perceptual and cognitive mechanisms responsible for any
improvements are not yet well understood. 9h30 Virtual Human Head Turning with Crowd Simulation. Ran Hu, Moses Adeagbo, Victoria Interrante, Stephen J. Guy. PDF

Title: Behavioral Dynamics Approach to Pedestrian and Crowd Behavior Slides
Experimental research on pedestrian and crowd dynamics is exploiting the power of VR. The behavioral dynamics approach seeks to explain individual and collective behavior as emerging from the dynamics of the agent-environment interaction. I will describe the development of a perceptually-grounded pedestrian model that aims to account for pedestrian and crowd dynamics. First, taking a local-to-global approach, we develop a pedestrian model based on human experiments in VR that captures basic behaviors such as steering, obstacle avoidance, and following. Elementary behaviors are modeled as nonlinear dynamical systems, which are linearly combined to generate more complex behavior. We are currently investigating local coupling between a human subject and a virtual crowd, to infer the neighborhood of interaction. Multi-agent simulations of the model are then used to predict global patterns of crowd behavior. Reciprocally, taking a global-to-local approach, we collect motion-capture data on human crowds in key scenarios. Patterns of crowd behavior are analyzed to estimate the local coupling and test the model. Scenarios such as Grand Central Station, Swarm, and Counterflow can be simulated with just a few model components. The results support the view that pedestrian and crowd dynamics emerge from local interactions, without internal models or plans, consistent with principles of self-organization. The resulting models can contribute to the generation of more realistic virtual human and crowd behavior. Bio: William H. Warren is Chancellor’s Professor of Cognitive, Linguistic, and Psychological Science at Brown University and Director of the Virtual Environment Navigation Lab (VENLab). He received his undergraduate degree from Hampshire College (1976), his Ph.D. in Experimental Psychology from the University of Connecticut (1982), did post-doctoral work at the University of Edinburgh (1983), and has been at Brown ever since. He uses virtual reality techniques to investigate the visual control of human action, including optic flow, locomotion, crowd behavior, spatial navigation, and the dynamics of perceptual-motor behavior. Warren is the recipient of a Fulbright Research Fellowship, an NIH Research Career Development Award, and Brown's Teaching Award for Excellence in the Life Sciences. 11h10 Microscopic crowd simulation.

Session 4 - 16h00 - 17h30: Virtual Teammates 16h00 Invited talk: Benjamin Lok, Computer and Information Sciences and Engineering Department, University of Florida, USA
Title: Learning within Virtual Human Teams Slides
In this talk, we will discuss the emerging field of virtual human groups to train interpersonal skills. We will explore systems that place users in amongst a team of virtual humans. We will explore the latest research into social dynamics, social presence, hardware, and software. Virtual human teams combine interactive graphics, natural language processing, artificial intelligence, human-computer interaction, mixed reality, and data mining to create learning experiences that help address difficult concepts such as speaking up to authority, addressing bullying, empathy, negotiation, and critical thinking. We will explore the latest results on using virtual human teams to empower teams of operating room personnel (e.g. nurses, surgical technicians, and anesthesia residents), to influence their decision making, and to influence their behaviors. The goal is to leverage virtual human teams to improve patient safety. Bio:
