Assoc. Prof. Yudai Honma has delivered a keynote speech at the “KKE NavVis Summit Japan 2025,” held at Shinagawa Intercity Hall on November 7, 2025. The title of his lecture was “Architectural Planning that Captures Interaction and Diversity: Mathematical Modeling to Connect People and Space.” This event, organized by the Kozo Keikaku Engineering Inc., is a summit designed to introduce NavVis’s latest technologies and application case studies. In addition to a presentation by NavVis CTO Georg Schroth, the event featured case study presentations by DENSO, Oura Kousoku, A-TEC, and Kajima Corporation.

　In this presentation, we introduced research that mathematically describes the diversity of values and interactions, using data on pedestrian flow and dwell times in architectural spaces as a starting point. Through mathematical optimization, convex space enumeration, and the use of detailed point cloud data, we quantitatively captured the relationship between people and space and presented new insights to inform design decisions. The event report included comments such as, “The presentation clearly conveyed the depth and complexity of the research—quantifying the invisible into numerical values to formulate hypotheses and create spatial models—making it a highly engaging session.”
