Welcome to the web site of Martin Knöll, architect and PhD student in architectural theory at University of Stuttgart. I work and conduct research in the fields of architectural and urban design, with a focus on health orientated planning. My current research interests include digital games and interactive media seeking to encourage health related behaviour change. As an urban researcher I interrogate how the knowledge about urbanism, urban design and architectural theory may contribute to improve effectiveness and play experience of digital health games. At the Lansdown Centre for Electronic Arts in London, I am dealing with the design and analysis of playful, locative media applications. What I aim to describe as Urban Health Games is being conceptualized in my writings and is being tested in prototypes. I am happy to share my most recent publications and on going research projects with you on this web site.
