We argue for a shift from a ‘human in the loop’ philosophy for visual analytics to a ‘human is the loop’ viewpoint, where the focus is on recognizing analysts’ work processes, and seamlessly fitting analytics into that existing interactive process. We survey a range of projects that provide visual analytic support contextually in the sensemaking loop, and outline a research agenda along with future challenges. %B Journal of Intelligent Information Systems %I Springer US %V 43 %P 411-435 %R 10.1007/s10844-014-0304-9 %0 Journal Article %J IEEE Transactions on Visualization and Computer Graphics %D 2014 %T A Survey of Software Frameworks for Cluster-Based Large High-Resolution Displays %A Chung, Haeyong %A Andrews, Christopher %A North, Chris %B IEEE Transactions on Visualization and Computer Graphics %I Institute of Electrical {&} Electronics Engineers ($łbrace$IEEE$\rbrace$) %V 20 %P 1158–1177 %8 8/2014 %R 10.1109/TVCG.2013.272 %0 Journal Article %J IEEE Transactions on Visualization and Computer Graphics %D 2013 %T The Impact of Physical Navigation on Spatial Organization for Sensemaking %A Andrews, Christopher %A North, Chris %B IEEE Transactions on Visualization and Computer Graphics %V 19 %P 2207 - 2216 %8 12/2013 %N 12 %!

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'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. %B 2012 IEEE Conference on Visual Analytics Science and Technology (VAST) %I IEEE %C Seattle, WA, USA %P 123 - 131 %@ 978-1-4673-4752-5 %R 10.1109/VAST.2012.6400559 %0 Conference Paper %B Proceedings of the International Working Conference on Advanced Visual Interfaces %D 2012 %T Designing large high-resolution display workspaces %A Endert, Alex %A Lauren Bradel %A Zeitz, Jessica %A Andrews, Christopher %A North, Chris %K large high-resolution displays %X Large, high-resolution displays have enormous potential to aid in scenarios beyond their current usage. Their current usages are primarily limited to presentations, visualization demonstrations, or conducting experiments. In this paper, we present a new usage for such systems: an everyday workspace. We discuss how seemingly small large-display design decisions can have significant impacts on users' perceptions of these workspaces, and thus the usage of the space. We describe the effects that various physical configurations have on the overall usability and perception of the display. We present conclusions on how to broaden the usage scenarios of large, high-resolution displays to enable frequent and effective usage as everyday workspaces while still allowing transformation to collaborative or presentation spaces. %B Proceedings of the International Working Conference on Advanced Visual Interfaces %S AVI '12 %I ACM %C New York, NY, USA %P 58–65 %@ 978-1-4503-1287-5 %U http://doi.acm.org/10.1145/2254556.2254570 %R 10.1145/2254556.2254570 %0 Conference Paper %B Proceedings of the 2011 annual conference extended abstracts on Human factors in computing systems %D 2011 %T ChairMouse: leveraging natural chair rotation for cursor navigation on large, high-resolution displays %A Endert, Alex %A Fiaux, Patrick %A Chung, Haeyong %A Stewart, Michael %A Andrews, Christopher %A North, Chris %K Embodied Interaction %K interaction design %K large display %X Large, high-resolution displays lead to more spatially based approaches. In such environments, the cursor (and hence the physical mouse) is the primary means of interaction. However, usability issues occur when standard mouse interaction is applied to workstations with large size and high pixel density. Previous studies show users navigate physically when interacting with information on large displays by rotating their chair. ChairMouse captures this natural chair movement and translates it into large-scale cursor movement while still maintaining standard mouse usage for local cursor movement. ChairMouse supports both active and passive use, reducing tedious mouse interactions by leveraging physical chair action. %B Proceedings of the 2011 annual conference extended abstracts on Human factors in computing systems %S CHI EA '11 %I ACM %C New York, NY, USA %P 571–580 %@ 978-1-4503-0268-5 %U http://doi.acm.org/10.1145/1979742.1979628 %R http://doi.acm.org/10.1145/1979742.1979628 %0 Conference Paper %B INTERACT 2011 %D 2011 %T Co-located Collaborative Sensemaking on a Large High-Resolution Display with Multiple Input Devices %A Katherine Vogt %A Lauren Bradel %A Andrews, Christopher %A North, Chris %A Endert, Alex %A Duke Hutchings %K co-located %K CSCW %K Large High Resolution Display %K large high-resolution display %K sensemaking %K Visual Analytics %B INTERACT 2011 %C Lisbon, Portugal %V 6947 %P 589 - 604 %@ 978-3-642-23771-3 %R 10.1007/978-3-642-23771-3_44 %0 Conference Paper %B AAAI'11, Workshop on Scalable Integration of Analytics and Visualization (WS-11-17) %D 2011 %T Helping Intelligence Analysts Make Connections %A Hossain, M.

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. %B Information Visualization %V 10 %P 341-355 %U http://ivi.sagepub.com/content/10/4/341.abstract %R 10.1177/1473871611415997 %0 Unpublished Work %D 2011 %T Space for Two to Think: Large, High-Resolution Displays for Co-located Collaborative Sensemaking %A Lauren Bradel %A Andrews, Christopher %A Endert, Alex %A Katherine Vogt %A Duke Hutchings %A North, Chris %K collaborative sensemaking %K high-resolution displays %K large %K Large High Resolution Display %K single display groupware %K Visual Analytics %B Technical Report TR-11-11 %I Computer Science, Virginia Tech %0 Conference Paper %B Proceedings of the 8th International Symposium on Visualization for Cyber Security %D 2011 %T Supporting the cyber analytic process using visual history on large displays %A Singh, Ankit %A Lauren Bradel %A Endert, Alex %A Kincaid, Robert %A Andrews, Christopher %A North, Chris %K interaction styles %K large high-resolution displays %K prototyping %K screen design %K user-centered design %B Proceedings of the 8th International Symposium on Visualization for Cyber Security %S VizSec '11 %I ACM %C New York, NY, USA %P 3:1–3:8 %@ 978-1-4503-0679-9 %U http://doi.acm.org/10.1145/2016904.2016907 %R 10.1145/2016904.2016907 %0 Conference Paper %B Proceedings of Graphics Interface 2011 %D 2011 %T Visual encodings that support physical navigation on large displays %A Endert, Alex %A Andrews, Christopher %A Lee, Yueh Hua %A North, Chris %K aggregation %K high-resolution display %K information visualization %K large %K perceptual scalability %B Proceedings of Graphics Interface 2011 %S GI '11 %I Canadian Human-Computer Communications Society %C School of Computer Science, University of Waterloo, Waterloo, Ontario, Canada %P 103–110 %@ 978-1-4503-0693-5 %G eng %U http://dl.acm.org/citation.cfm?id=1992917.1992935 %0 Conference Paper %B CHI '10: Proceedings of the 28th international conference on Human factors in computing systems %D 2010 %T Space to think: large high-resolution displays for sensemaking %A Andrews, Christopher %A Endert, Alex %A North, Chris %K LHRD %B CHI '10: Proceedings of the 28th international conference on Human factors in computing systems %I ACM %C New York, NY, USA %P 55–64 %@ 978-1-60558-929-9 %R http://doi.acm.org/10.1145/1753326.1753336 %0 Conference Paper %B IEEE VAST Conference %D 2010 %T VizCept: Supporting Synchronous Collaboration for Constructing Visualizations in Intelligence Analysis %A Chung, Haeyong %A Yang, S. %A Massjouni, N. %A Andrews, Christopher %A Kanna, R. %A North, Chris %K Visual Analytics %B IEEE VAST Conference %C Salt Lake City, Utah %8 10/2010 %0 Conference Paper %B Computational Science and Engineering, 2009.
