In a recent interview with TransforMA, Till Nagel, head of the Human Data Interaction Lab at Hochschule Mannheim, discussed ongoing research and projects at the lab. A central topic was the Smart City Mannheim project, a collaboration between the City of Mannheim, University of Mannheim, and University of Hamburg.
Together with his colleagues and partners, Nagel explores how data visualization can offer new insights into urban phenomena. In the interview, he highlights our work on visualizing traffic flows in AR, showing heat distribution patterns, and analyzing emergency routes, demonstrating how these approaches can help make complex urban data more comprehensible and actionable.
The video interview provides an overview of our research, including how LLMs can be used to construct visualizations (Hey ChatGPT), how to embed visualizations in an urban landscape (AR DXP), and how students analyzed real-time data from a large park area (BUGA Vis).
