Title: Where are we? Activity awareness in geocollaboration
Abstract. Effective collaboration requires participants to be aware of one another in many respects - aware of what keys were pressed by other people, aware of what data objects were changed by others, etc. We have been studying awareness in complex collaborative activities such as emergency planning and information analysis. We use the term activity awareness to refer to awareness of skills, technical information, goals, decision criteria, and values of collaborative partners. I will talk about a cycle of design research in which we studied an emergency planning scenario, designed a geo-collaborative system to support it, and then investigated team performance using that system.
Bio. John M. Carroll is Distinguished Professor of Information Sciences and Technology at the Pennsylvania State University. His research is in methods and theory in human-computer interaction, particularly as applied to Internet tools for collaborative learning and problem solving, and design of interactive information systems. He is editor of the Synthesis Lectures on Human-Centered Informatics. Carroll has received the Rigo Award and the CHI Lifetime Achievement Award from ACM, the Silver Core Award from IFIP, the Goldsmith Award from IEEE. He is a fellow of AAAS, ACM, IEEE, the Human Factors and Ergonomics Society, and the Association for Psychological Science. In 2012, he received an honorary doctorate in engineering from Universidad Carlos III de Madrid.
Title. The constructive nature of neural scene representation
Abstract. A central question in human visual cognition is how we construct a coherent scene percept, rapidly recognizing scene structure while integrating multiple views that constantly change over time. Past studies have shown that a number of brain regions are involved in scene understanding, including the parahippocampal place area and the retrosplenial cortex. Here I examine the nature of the representations in these networks of scene processing regions, using fMRI repetition attenuation and multi-voxel pattern analysis. First I show how the brain represents geometric scene properties, such as spatial layout, spatial size and boundary structure. Second, I show how the brain represents functional properties of a scene, such as the functional affordance of a boundary and navigability of a scene. Finally, I show the functional architecture of neural scene representation that supports the integrated scene percept that encompasses multiple views over time. Altogether, my results show how multiple scene processing regions play distinct but complementary roles in constructing the rich and integrated scene representation that underlies our everyday experience of the visual world.
Bio. Soojin Park is an Assistant Professor of the Department of Cognitive Science at Johns Hopkins University. Her laboratory at Johns Hopkins uses functional magnetic resonance imaging (fMRI) to investigate the neural mechanisms underlying human scene perception and spatial navigation. Her recent work focuses on using fMRI to understand how different properties of scenes are represented in distinctive regions of a scene network and how the functionality of space interacts with visual geometry. She got her Ph.D. in psychology from Marvin Chun’s lab at Yale University, and did her postdoctoral work with Aude Oliva at MIT.
Title. Geographic Cognition and Cognitive Geography: Different from Spatial?
Abstract. ‘Geographic’ is distinguished from ‘spatial’ mostly by the size, scale, and distances involved. But much of the empirical work on ‘geographic’ cognition has involved testing using maps. There has been considerable research on scales of spaces, and how cognition of entities and relations at different scales may be qualitatively different. The relationship between ‘spatial’ and ‘geographic’ may resemble a Venn diagram with some research topics in each region. This presentation will review the research topic from this perspective and then describe some research in less common areas. Johannes Granö defined a ‘landscape’ scale as being qualitatively different from the proximity near the observer. This claim is intriguing but has not yet been tested empirically. And, is ‘landscape’ exactly equivalent to ‘geographic’? One research topic at landscape scale is the recognition of landscape entities, as well as their classification. Landscape entity types vary across cultures and languages. Some examples will be presented.
Bio. David M. Mark is a SUNY Distinguished Professor Emeritus in the Department of Geography at the University at Buffalo (UB), the State University of New York. He retired in 2013. Mark served as Director of the Buffalo site of the National Center for Geographic Information and Analysis (NCGIA) from 1995 until his retirement. Mark served as Project Director of the University at Buffalo’s two NSF-funded Integrative Graduate Education and Research Traineeship (IGERT) projects in Geographic Information Science, projects that together have supported more than 60 doctoral level trainees in seven academic departments. He also is a member of UB's Center for Cognitive Science. Mark has written or co-authored more than 250 publications, including 85 refereed articles, 8 edited books, 40 book chapters, 73 conference proceedings articles, and more than 40 technical reports. He has made more than 260 academic presentations, more than two thirds at professional meetings, and the others as invited talks at universities and government agencies. Previously, Mark served as Vice-chair (1987-88) and Chair (1988-89) of the Geographic Information Systems Specialty Group of the Association of American Geographers and Chair of the Technology Interest Group, Canadian Cartographic Association (1987-89). Mark was involved in the founding of the University Consortium for Geographic Information Science, and later served as President of the UCGIS (1998). He has been named the UCGIS Researcher of the Year (2004) and UCGIS Educator of the Year (2009), and in 2010 was a member of the inaugural class of UCGIS Fellows. He also has served on numerous international editorial boards and program committees, and was program co-chair for Auto Carto 10 (1991), COSIT'99, COSIT'05, and GIScience 2000 and 2002.
