This report represents a committee summary of the current state of knowledge regarding aftereffects and sense of presence in virtual environments (VEs). The work presented in this article, and the proposed research agenda, are the result of a special session that was set up in the framework of the Seventh International Conference on Human Computer Interaction. Recommendations were made by the committee regarding research needs in aftereffects and sense of presence, and, where possible, priorities were suggested. The research needs were structured in terms of the short, medium, and long term and, if followed, should lead toward the effective use of VE technology. The 2 most critical research issues identified were (a) standardization and use of measurement approaches for aftereffects and (b) identification and prioritization of sensorimotor discordances that drive aftereffects. Identification of aftereffects countermeasures (i.e., techniques to assist users in readily transitioning between the real and virtual worlds), reduction of system response latencies, and improvements in tracking technology were also thought to be of critical importance.

Bei der virtuellen Planung, Auslegung und Inbetriebnahme steigen die Anforderungen an die Aussagekraft Digitaler Zwillinge zur umfassenden Abbildung der Interaktionen zwischen Prozess, Maschine, Steuerungssystem und Bediener. Die Zunahme der Modellkomplexität eines Digitalen Zwillings stellt die Echtzeitsimulation vor neue Herausforderungen. Dieser Beitrag stellt eine Echtzeit-Co-Simulations Plattform für die Virtuelle Inbetriebnahme mit Hilfe eines Digitalen Zwillings vor. Diese umfasst (i) die Integration leistungsfähiger technologiespezifischer Simulationsmodelle durch Ansätze zur Modellintegration und (ii) die Echtzeit-Co-Simulation auf Basis von Separations-, Parallelisierungs-, Synchronisations- und Datenaustauschmechanismen.
