    Floor Plan Generation for Simple Polygons with Support for Holes
    (GI VR / AR Workshop, 2024) Lerm, Julius; Schwandt, Tobias; Broll, Wolfgang
    This paper presents an algorithm for the real-time, automatic generation of a house floor plan and a 3D model for a given silhouette. In contrast to the most common variants to date, floor plans can be created for any outline shape, including holes. Starting from initial room points, the walls between the individual rooms are gradually created, straightened and simplified until a credible floor plan is created. A suitable room distribution algorithm ensures that the generated room divisions are uniform. Depending on the division and size distribution of the rooms, different house types (e.g. apartments or retail stores) can be generated. The results show that the generation of floor plans into a given shape can be reduced to the distribution of initial spatial points. Placed interior walls often use existing edges and corners and follow existing geometries. With a clever distribution of room points, any number of credible floor plans can be generated in realtime.

    Tick-tock: Revisiting the Influence of Zeitgebers and Cognitive Load on Time Judgments during and after VR Immersion
    (Proceedings of Mensch und Computer 2024, 2024) Andrich, Aliya; Weidner, Florian; Broll, Wolfgang
    Prior research has explored the impact of virtual reality (VR) on human time perception without definitive conclusions. To enhance understanding, we replicated a seminal study, refining it and introducing novel variables. Building upon the original study, we investigated the influence of virtual sun speed and cognitive workload on time perception in a VR environment. Our experiment involved 70 participants estimating time intervals under varying cognitive demands. In addition to assessing time perception during immersion, we examined post-VR time estimations. Contrary to the original study, virtual sun movements did not affect time judgments in VR. However, cognitive workload had a consistent effect, which is consistent with previous findings. Notably, VR immersion affected post-VR time perception of short intervals, a previously overlooked aspect. We contribute to the field by deepening the understanding of time perception dynamics during and after VR experiences and refining earlier findings through replication.
