Our examination of the use of large, high-resolution displays from an embodied perspective has lead directly to the development of a new sensemaking environment called Analyst{\textquoteright}s Workspace (AW). AW leverages the embodied resources made more accessible through the physical nature of the display to create a spatial workspace. By combining spatial layout of documents and other artifacts with an entity-centric, explorative investigative approach, AW aims to allow the analyst to externalize elements of the sensemaking process as a part of the investigation, integrated into the visual representations of the data itself. In this paper, we describe the various capabilities of AW and discuss the key principles and concepts underlying its design, emphasizing unique design principles for designing visual analytic tools for large, high-resolution displays.}, isbn = {978-1-4673-4752-5}, doi = {10.1109/VAST.2012.6400559}, author = {Andrews, Christopher and North, Chris} } @conference {Endert:2012:DLH:2254556.2254570, title = {Designing large high-resolution display workspaces}, booktitle = {Proceedings of the International Working Conference on Advanced Visual Interfaces}, series = {AVI {\textquoteright}12}, year = {2012}, pages = {58{\textendash}65}, publisher = {ACM}, organization = {ACM}, address = {New York, NY, USA}, abstract = {Large, high-resolution displays have enormous potential to aid in scenarios beyond their current usage.

ChairMouse captures this natural chair movement and translates it into large-scale cursor movement while still maintaining standard mouse usage for local cursor movement.

The additional pixels are especially useful for information visualization where scalability has typically been limited by the number of pixels available on a display. But how will visualizations for larger displays need to fundamentally differ from visualizations on desktop displays? Are the basic visualization design principles different? With this potentially new design paradigm comes questions such as whether the relative effectiveness of various graphical encodings are different on large displays, which visualizations and datasets benefit the most, and how interaction with visualizations on large, high-resolution displays will need to change. As we explore these possibilities, we shift away from the technical limitations of scalability imposed by traditional displays (e.g. number of pixels) to studying the human abilities that emerge when these limitations are removed. There is much potential for information visualizations to benefit from large, high-resolution displays, but this potential will only be realized through understanding the interaction between visualization design, perception, interaction techniques, and the display technology. In this paper we present critical design issues and outline some of the challenges and future opportunities for designing visualizations for large, high-resolution displays. We hope that these issues, challenges, and opportunities will provide guidance for future research in this area.}, doi = {10.1177/1473871611415997}, url = {http://ivi.sagepub.com/content/10/4/341.abstract}, author = {Andrews, Christopher and Endert, Alex and Yost, Beth and North, Chris} } @unpublished {120, title = {Space for Two to Think: Large, High-Resolution Displays for Co-located Collaborative Sensemaking}, journal = {Technical Report TR-11-11}, year = {2011}, publisher = {Computer Science, Virginia Tech}, keywords = {collaborative sensemaking, high-resolution displays, large, Large High Resolution Display, single display groupware, Visual Analytics}, author = {Lauren Bradel and Andrews, Christopher and Endert, Alex and Katherine Vogt and Duke Hutchings and North, Chris} } @conference {Singh:2011:SCA:2016904.2016907, title = {Supporting the cyber analytic process using visual history on large displays}, booktitle = {Proceedings of the 8th International Symposium on Visualization for Cyber Security}, series = {VizSec {\textquoteright}11}, year = {2011}, pages = {3:1{\textendash}3:8}, publisher = {ACM}, organization = {ACM}, address = {New York, NY, USA}, keywords = {interaction styles, large high-resolution displays, prototyping, screen design, user-centered design}, isbn = {978-1-4503-0679-9}, doi = {10.1145/2016904.2016907}, url = {http://doi.acm.org/10.1145/2016904.2016907}, author = {Singh, Ankit and Lauren Bradel and Endert, Alex and Kincaid, Robert and Andrews, Christopher and North, Chris} } @conference {Endert:2011:VES:1992917.1992935, title = {Visual encodings that support physical navigation on large displays}, booktitle = {Proceedings of Graphics Interface 2011}, series = {GI {\textquoteright}11}, year = {2011}, pages = {103{\textendash}110}, publisher = {Canadian Human-Computer Communications Society}, organization = {Canadian Human-Computer Communications Society}, address = {School of Computer Science, University of Waterloo, Waterloo, Ontario, Canada}, keywords = {aggregation, high-resolution display, information visualization, large, perceptual scalability}, isbn = {978-1-4503-0693-5}, url = {http://dl.acm.org/citation.cfm?id=1992917.1992935}, author = {Endert, Alex and Andrews, Christopher and Lee, Yueh Hua and North, Chris} } @conference {1753336, title = {Space to think: large high-resolution displays for sensemaking}, booktitle = {CHI {\textquoteright}10: Proceedings of the 28th international conference on Human factors in computing systems}, year = {2010}, pages = {55{\textendash}64}, publisher = {ACM}, organization = {ACM}, address = {New York, NY, USA}, keywords = {LHRD}, isbn = {978-1-60558-929-9}, doi = {http://doi.acm.org/10.1145/1753326.1753336}, author = {Andrews, Christopher and Endert, Alex and North, Chris} } @conference {111, title = {VizCept: Supporting Synchronous Collaboration for Constructing Visualizations in Intelligence Analysis}, booktitle = {IEEE VAST Conference}, year = {2010}, month = {10/2010}, address = {Salt Lake City, Utah}, keywords = {Visual Analytics}, author = {Chung, Haeyong and Yang, S. and Massjouni, N. and Andrews, Christopher and Kanna, R. and North, Chris} } @conference {5283504, title = {Co-located Many-Player Gaming on Large High-Resolution Displays}, booktitle = {Computational Science and Engineering, 2009.
