The Realities and Realms colloquium focuses on the role of computation and robotics in landscape architecture and the expanding sensorial field of the built environment. These hybrid grounds of operation merge anthropogenic perception and technological mediation. As sensing networks expand, data grows exponentially in quantity and ubiquity, building an increasingly abstract landscape of information. How such data is elucidated, curated, and augmented forms new realities for design. This colloquium will explore design methodologies that address concurrent physical and virtual realms and the realities in which they operate. In this context, a realm is a lens through which we sense an environment and a reality is place within which we take action. The Realities and Realms colloquium engages select practitioners, theorists, and academics for an afternoon to explore the future of responsive technologies to interpret and modify environment. Panelists will posit trajectories that frame the role of responsive technologies to imagine, choreograph, and evolve cyborg landscapes and synthetic ecologies. The colloquium will be organized in two panel sessions followed by open discussions, exploring the tools, practice, theories, and futures of responsive technologies in landscape architecture.
