We present the concept of CD to characterize students' capacity for making dimensionally complex insights from data. Using this concept, we build a vocabulary and methodology to support a student’s progression in terms of growth from low cognitive dimensionality (LCD) to high cognitive dimensionality (HCD). Crucially, students do not need high-level math skills to develop HCD. Rather, we use our own tool called Andromeda that enables human-computer interaction with a common, easy to interpret visualization method called Weighted Multidimensional Scaling (WMDS) to promote the idea of making high-dimensional insights. In this paper, we present Andromeda and report findings from a series of classroom assignments to 18 graduate students. These assignments progress from spreadsheet manipulations to statistical software such as R and finally to the use of Andromeda. In parallel with the assignments, we saw students' CD begin low and improve. %I Virginia Tech %C Blacksburg %9 Technical Report %0 Journal Article %J IEEE Computer Graphics and Applications %D 2015 %T Semantic Interaction: Coupling Cognition and Computation through Usable Interactive Analytics %A Endert, Alex %A Chang, Remco %A North, Chris %A Zhou, Michelle %B IEEE Computer Graphics and Applications %P 6-11 %8 07/2015 %N July/August %0 Journal Article %J Journal of Intelligent Information Systems %D 2014 %T The human is the loop: new directions for visual analytics %A Endert, Alex %A Hossain, M.

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 Computer Graphics and Applications, IEEE %D 2014 %T Semantic Interaction for Visual Analytics: Toward Coupling Cognition and Computation %A Endert, Alex %K Alex Endert %K Analytical models %K Cognition %K computation %K Computational modeling %K computer graphics %K Data models %K Data visualization %K graphics %K human computer interaction %K human-computer interaction %K IN-SPIRE %K Semantic interaction %K Semantics %K Visual Analytics %K visualization %B Computer Graphics and Applications, IEEE %V 34 %P 8-15 %8 July %R 10.1109/MCG.2014.73 %0 Conference Paper %B KDD 2014 Workshop on Interactive Data Exploration and Analytics (IDEA) %D 2014 %T Toward Usable Interactive Analytics: Coupling Cognition and Computation %A Endert, Alex %A North, Chris %A Chang, Remco %A Zhou, Michelle %B KDD 2014 Workshop on Interactive Data Exploration and Analytics (IDEA) %U http://poloclub.gatech.edu/idea2014/papers/p52-endert.pdf %0 Journal Article %J IEEE Computer Graphics and Applications %D 2013 %T Beyond Control Panels: Direct Manipulation for Visual Analytics %A Endert, Alex %A Lauren Bradel %A North, Chris %B IEEE Computer Graphics and Applications %V 33 %P 6 - 13 %8 07/2013 %N 4 %!

Sensemaking may take place at the end of the pipeline when users have an opportunity to observe, digest, and internalize any information displayed. However, some visualizations mask meaningful data structures when model or algorithm constraints (e.g., parameter specifications) contradict information in the data. Yet, due to the linearity of the pipeline, users do not have a natural means to adjust the displays. In this paper, we present a framework for creating dynamic data displays that rely on both mechanistic data summaries and expert judgement. The key is that we develop both the theory and methods of a new human-data interaction to which we refer as “ Visual to Parametric Interaction” (V2PI). With V2PI, the pipeline becomes bi-directional in that users are embedded in the pipeline; users learn from visualizations and the visualizations adjust to expert judgement. We demonstrate the utility of V2PI and a bi-directional pipeline with two examples. %B PLoS ONE %V 8 %P e50474 %8 03/2013 %N 3 %!

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 IEEE VAST 2012 (Extended Abstract) (Honorable Mention for Good Use of Coordinated Displays) %D 2012 %T Dynamic Analysis of Large Datasets with Animated and Correlated Views %A Yong Cao %A Reese Moore %A Peng Mi %A Endert, Alex %A North, Chris %A Randy Marchany %X In this paper, we introduce a GPU-accelerated visual analytics tool, AVIST. By adopting the in-situ visualization architecture on the GPUs, AVIST supports real-time data analysis and visualization of massive scale datasets, such as VAST 2012 Challenge dataset. The design objective of the tool is to identify temporal patterns from large and complex data. To achieve this goal, we introduce three unique features: automatic animation, disjunctive data filters, and time-synced visualization of multiple datasets. %B IEEE VAST 2012 (Extended Abstract) (Honorable Mention for Good Use of Coordinated Displays) %0 Conference Paper %B Proceedings of the International Working Conference on Advanced Visual Interfaces %D 2012 %T How spatial layout, interactivity, and persistent visibility affect learning with large displays %A Ragan, Eric D. %A Endert, Alex %A Bowman, Doug A. %A Francis Quek %K interactivity %K large displays %K learning %K memory %K use of space %X Visualizations often use spatial representations to aid understanding, but it is unclear what properties of a spatial information presentation are most important to effectively support cognitive processing. This research explores how spatial layout and view control impact learning and investigates the role of persistent visibility when working with large displays. We performed a controlled experiment with a learning activity involving memory and comprehension of a visually represented story. We compared performance between a slideshow-type presentation on a single monitor and a spatially distributed presentation among multiple monitors. We also varied the method of view control (automatic vs. interactive). Additionally, to separate effects due to location or persistent visibility with a spatially distributed layout, we controlled whether all story images could always be seen or if only one image could be viewed at a time. With the distributed layouts, participants maintained better memory of the associated locations where information was presented. However, learning scores were significantly better for the slideshow presentation than for the distributed layout when only one image could be viewed at a time. %B Proceedings of the International Working Conference on Advanced Visual Interfaces %S AVI '12 %I ACM %C New York, NY, USA %P 91–98 %@ 978-1-4503-1287-5 %U http://doi.acm.org/10.1145/2254556.2254576 %R 10.1145/2254556.2254576 %0 Journal Article %J IEEE Transactions on Visualization and Computer Graphics %D 2012 %T Semantic Interaction for Sensemaking: Inferring Analytical Reasoning for Model Steering %A Endert, Alex %A Fiaux, Patrick %A North, Chris %X Visual analytic tools aim to support the cognitively demanding task of sensemaking. Their success often depends on the ability to leverage capabilities of mathematical models, visualization, and human intuition through flexible, usable, and expressive interactions. Spatially clustering data is one effective metaphor for users to explore similarity and relationships between information, adjusting the weighting of dimensions or characteristics of the dataset to observe the change in the spatial layout. Semantic interaction is an approach to user interaction in such spatializations that couples these parametric modifications of the clustering model with users' analytic operations on the data (e.g., direct document movement in the spatialization, highlighting text, search, etc.). In this paper, we present results of a user study exploring the ability of semantic interaction in a visual analytic prototype, ForceSPIRE, to support sensemaking. We found that semantic interaction captures the analytical reasoning of the user through keyword weighting, and aids the user in co-creating a spatialization based on the user's reasoning and intuition. %B IEEE Transactions on Visualization and Computer Graphics %V 18 %P 2879 - 2888 %8 12/2012 %N 12 %!

For example, dimensionality reduction methods use various similarity metrics to visualize textual document collections in a spatial metaphor, where similarities between documents are approximately represented through their relative spatial distances to each other in a 2D layout. This metaphor is designed to mimic analysts' mental models of the document collection and support their analytic processes, such as clustering similar documents together. However, in current methods, users must interact with such visualizations using controls external to the visual metaphor, such as sliders, menus, or text fields, to directly control underlying model parameters that they do not understand and that do not relate to their analytic process occurring within the visual metaphor. In this paper, we present the opportunity for a new design space for visual analytic interaction, called semantic interaction, which seeks to enable analysts to spatially interact with such models directly within the visual metaphor using interactions that derive from their analytic process, such as searching, highlighting, annotating, and repositioning documents. Further, we demonstrate how semantic interactions can be implemented using machine learning techniques in a visual analytic tool, called ForceSPIRE, for interactive analysis of textual data within a spatial visualization. Analysts can express their expert domain knowledge about the documents by simply moving them, which guides the underlying model to improve the overall layout, taking the user's feedback into account. %B Proceedings of the 2012 ACM annual conference on Human Factors in Computing Systems %S CHI '12 %I ACM %C New York, NY, USA %P 473–482 %@ 978-1-4503-1015-4 %U http://doi.acm.org/10.1145/2207676.2207741 %R 10.1145/2207676.2207741 %0 Conference Paper %B Proceedings of the International Working Conference on Advanced Visual Interfaces %D 2012 %T The semantics of clustering: analysis of user-generated spatializations of text documents %A Endert, Alex %A Fox, Seth %A Maiti, Dipayan %A Leman, Scotland %A North, Chris %K clustering %K text analytics %K Visual Analytics %K visualization %X Analyzing complex textual datasets consists of identifying connections and relationships within the data based on users' intuition and domain expertise. In a spatial workspace, users can do so implicitly by spatially arranging documents into clusters to convey similarity or relationships. Algorithms exist that spatialize and cluster such information mathematically based on similarity metrics. However, analysts often find inconsistencies in these generated clusters based on their expertise. Therefore, to support sensemaking, layouts must be co-created by the user and the model. In this paper, we present the results of a study observing individual users performing a sensemaking task in a spatial workspace. We examine the users' interactions during their analytic process, and also the clusters the users manually created. We found that specific interactions can act as valuable indicators of important structure within a dataset. Further, we analyze and characterize the structure of the user-generated clusters to identify useful metrics to guide future algorithms. Through a deeper understanding of how users spatially cluster information, we can inform the design of interactive algorithms to generate more meaningful spatializations for text analysis tasks, to better respond to user interactions during the analytics process, and ultimately to allow analysts to more rapidly gain insight. %B Proceedings of the International Working Conference on Advanced Visual Interfaces %S AVI '12 %I ACM %C New York, NY, USA %P 555–562 %@ 978-1-4503-1287-5 %U http://doi.acm.org/10.1145/2254556.2254660 %R 10.1145/2254556.2254660 %0 Conference Paper %B Proceedings of the 2011 annual conference extended abstracts on Human factors in computing systems %D 2011 %T Analytic provenance: process+interaction+insight %A North, Chris %A Chang, Remco %A Endert, Alex %A Dou, Wenwen %A May, Richard %A Pike, Bill %A Fink, G. %K analytic provenance %K user interaction %K Visual Analytics %K visualization %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 33–36 %@ 978-1-4503-0268-5 %G eng %U http://doi.acm.org/10.1145/1979742.1979570 %R http://doi.acm.org/10.1145/1979742.1979570 %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 Proceedings of the 2011 annual conference extended abstracts on Human factors in computing systems %D 2011 %T The effects of spatial layout and view control on cognitive processing %A Ragan, Eric D. %A Endert, Alex %A Bowman, Doug A. %A Francis Quek %K information processing %K interactivity %K learning %K spatial memory %K visualization %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 2005–2010 %@ 978-1-4503-0268-5 %G eng %U http://doi.acm.org/10.1145/1979742.1979921 %R http://doi.acm.org/10.1145/1979742.1979921 %0 Journal Article %J Information Visualization %D 2011 %T Information visualization on large, high-resolution displays: Issues, challenges, and opportunities %A Andrews, Christopher %A Endert, Alex %A Yost, Beth %A North, Chris %X Larger, higher-resolution displays are becoming accessible to a greater number of users as display technologies decrease in cost and software for the displays improves. 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 Conference Paper %B Visual Analytics Science and Technology (VAST), 2011 IEEE Conference on %D 2011 %T Observation-level interaction with statistical models for visual analytics %A Endert, Alex %A Chao Han %A Maiti, Dipayan %A House, Leanna %A Leman, Scotland %A North, Chris %K data analysis %K data interactive visual exploration %K data visualisation %K exploratory interaction %K expressive interaction %K generative topographic mapping %K multidimensional scaling %K observation-level interaction %K parameter adjustments %K principal component analysis %K probabilistic principal component analysis %K probability %K sensemaking process %K statistical models %K Visual Analytics %X In visual analytics, sensemaking is facilitated through interactive visual exploration of data. Throughout this dynamic process, users combine their domain knowledge with the dataset to create insight. Therefore, visual analytic tools exist that aid sensemaking by providing various interaction techniques that focus on allowing users to change the visual representation through adjusting parameters of the underlying statistical model. However, we postulate that the process of sensemaking is not focused on a series of parameter adjustments, but instead, a series of perceived connections and patterns within the data. Thus, how can models for visual analytic tools be designed, so that users can express their reasoning on observations (the data), instead of directly on the model or tunable parameters? Observation level (and thus #x201C;observation #x201D;) in this paper refers to the data points within a visualization. In this paper, we explore two possible observation-level interactions, namely exploratory and expressive, within the context of three statistical methods, Probabilistic Principal Component Analysis (PPCA), Multidimensional Scaling (MDS), and Generative Topographic Mapping (GTM). We discuss the importance of these two types of observation level interactions, in terms of how they occur within the sensemaking process. Further, we present use cases for GTM, MDS, and PPCA, illustrating how observation level interaction can be incorporated into visual analytic tools. %B Visual Analytics Science and Technology (VAST), 2011 IEEE Conference on %P 121 -130 %8 oct. %R 10.1109/VAST.2011.6102449 %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 IEEE Workshop on Interactive Visual Text Analytics for Decision Making at VisWeek 2011 %D 2011 %T Unifying the Sensemaking Loop with Semantic Interaction %A Endert, Alex %A Fiaux, Patrick %A North, Chris %K Visual Analytics %B IEEE Workshop on Interactive Visual Text Analytics for Decision Making at VisWeek 2011 %C Providence, RI %8 10/2011 %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 Collaborative Technologies and Systems (CTS), 2010 International Symposium on %D 2010 %T Towards efficient collaboration in cyber security %A Hui, P. %A Bruce, J. %A Fink, G. %A Gregory, M. %A Best, D. %A McGrath, L. %A Endert, Alex %K collaboration %K cyber security analysts %K groupware %K security bulletins %K security of data %B Collaborative Technologies and Systems (CTS), 2010 International Symposium on %P 489 -498 %R 10.1109/CTS.2010.5478473 %0 Conference Paper %B IEEE VAST 2009 (Extended Abstract) (Awarded Special Contributions to the VAST Challenge Contest) %D 2009 %T Professional Analysts using a Large, High-Resolution Display %A Endert, Alex %A Andrews, Christopher %A North, Chris %K Large High Resolution Display %K Visual Analytics %B IEEE VAST 2009 (Extended Abstract) (Awarded Special Contributions to the VAST Challenge Contest) %0 Conference Paper %B Visual Analytics Science and Technology, 2009.
