The talk introduces recent work of Würzburg’s HCI group at the Translational Neurotechnology Lab of the University of Freiburg. We will begin with a discussion of the general psychophysics of Virtual Reality and specifically of Avatar Technology and how they are useful for immersive human-computer interfaces enabling studies of, e.g., Presence, believability, Interpersonal Synchronization (IPS), the Illusion of Virtual Body Ownership (IVBO), or emotional response. Several examples will highlight the influence of embodiment and avatar appearance in Virtual Reality on these effects. The talk will illustrate potential obstacles as well as solutions to generate believable embodiment, e.g., how to generate life-like avatars and their animation in real-time. This is followed by a short reflection on timeliness as a critical requirement of the simulator technology to provide reusable and timeliness-aware systems controlling latency and jitter, pressing problems for many VR and AR systems. We will see how API-usability is strengthening the software quality of Real-Time Interactive Systems (RIS) in general and of multimodal VR systems specifically, and what we can expect from today’s operating systems and programming languages in terms of required timeliness given concurrency conditions. Along the way, we will have a look into typical applications of immersive systems, i.e., for therapy and training as well as for computer games and their serious application.
Prof. Dr. Marc Erich Latoschik, Universität Würzburg
Marc studied mathematics and computer sciences at the University of Paderborn, the New York Institute of Technology and the Bielefeld University. After several accompanying years in the computer business, he received his PhD in 2001 in the area of multimodal–gesture and speech–interaction for Virtual Reality.
He headed the AI & VR Lab at the Bielefeld University until 2007, became professor for media informatics at the University of Applied Sciences (HTW) in Berlin, and founded the Intelligent Graphics Group at Bayreuth University in 2009.
Marc holds the chair for human-computer interaction at Würzburg University since 2011. His work is interdisciplinary oriented towards human-computer interaction interconnecting real-time 3D graphics and simulation, virtual and augmented environments, Artificial Intelligence, and cognitive sciences.
