Nicolai Marquardt is a Lecturer in Physical Computing at University College London. At the UCL Interaction center he is working in the research areas of ubiquitous computing, physical user interfaces and interactive surfaces. In particular, his research of Proxemic Interactions focuses on how to exploit knowledge about people’s and devices spatial relationships in interaction design. He graduated with a Ph.D. in Computer Science from the Interactions Lab at the University of Calgary, and joined Microsoft Research in Cambridge and Redmond as an intern during his graduate studies. Together with Saul Greenberg, Sheelagh Carpendale, and Bill Buxton he is co-author of Sketching User Experiences: The Workbook (Morgan-Kaufmann 2012). See: http://www.nicolaimarquardt.com.
Saul Greenberg is a Full Professor and Industrial Research Chair in the Department of Computer Science at the University of Calgary. While he is a computer scientist by training, the work by Saul and his talented students typifies the cross-discipline aspects of Human Computer Interaction, Computer Supported Cooperative Work, and Ubiquitous Computing. He and his crew are well known for their development of toolkits, innovative system designs based on observations of social phenomenon, articulation of design-oriented social science theories, and refinement of evaluation methods. He is a Fellow of the ACM, received the CHCCS Achievement award, and was elected to the ACM CHI Academy for his overall contributions to the field of Human Computer Interaction. Together with Nicolai Marquardt, Sheelagh Carpendale and Bill Buxton he is the co-author of Sketching User Experiences: The Workbook (Morgan-Kaufmann 2012) as well several other books on Human Computer Interaction.
