UGOD Seminar | Preliminary study on human activity in cyber-physical space and urban informatics

With the rapid pace of urbanization and the rise of intelligent technologies, human activity patterns are becoming increasingly diverse. These activities are no longer confined to the physical spaces people inhabit; online cyber spaces have become a significant and integral part of daily life. Urban informatics, an emerging interdisciplinary field, provides the theoretical and technical foundation for the development of modern smart cities. This report begins by outlining the current state of urban informatics, highlighting its five key dimensions: urban sensing, urban big data infrastructure, urban computing, urban science, and urban systems and applications. Building on this foundation, the report explores methods for perceiving human activities in integrated cyber-physical spaces, extracting human activity chains within these spaces, and analyzing network construction based on these activities. The accelerated urbanization process, frequent mass migrations, and the intensification of human activities and mutuality both online and offline present new challenges for urban science.
