How to evaluate data visualizations across different levels of understanding [article]

Alyxander Burns, Cindy Xiong, Steven Franconeri, Alberto Cairo, Narges Mahyar
2020 arXiv   pre-print
If this level-independence holds across new tested visualizations, the taxonomy could serve to inspire more targeted evaluations of levels of understanding that are relevant to a communication goal.  ...  We describe each level of the framework and provide examples for how it can be applied to evaluate the efficacy of data visualizations along six levels of knowledge acquisition - knowledge, comprehension  ...  We sought a more systematic way to evaluate these levels of understanding and how each level might differ depending on a visualization's design -understanding is far more than extraction of individual  ...

The Shaping of Information by Visual Metaphors

C. Ziemkiewicz, R. Kosara
2008 IEEE Transactions on Visualization and Computer Graphics  
These findings are a first step towards illuminating how visual metaphors shape user understanding and have significant implications for the evaluation, application, and theory of visualization.  ...  To investigate this claim, we conducted an experiment to test the effects of visual metaphor and verbal metaphor on the understanding of tree visualizations.  ...  Department of Homeland Security Program, under the auspices of the SouthEast Regional Visualization and Analytics Center.  ...

Navigating reductionism and holism in evaluation

Michael Correll, Eric Alexander, Danielle Albers, Alper Sarikaya, Michael Gleicher
2014 Proceedings of the Fifth Workshop on Beyond Time and Errors Novel Evaluation Methods for Visualization - BELIV '14  
In this position paper, we enumerate two approaches to the evaluation of visualizations which are associated with two approaches to knowledge formation in science: reductionism, which holds that the understanding  ...  While we believe that each approach has benefits for evaluating visualizations, we claim that strict adherence to one perspective or the other can make it difficult to generate a full evaluative picture  ...  While reductionism in its extreme is embodied in traditional psychophysics evaluations that are devoid of data and problem contexts, reductionist evaluations have been used in visualization to aid in understanding  ...

Evaluation of Geovisualization Designs for the Cognition of Movement in Space and Time

Crystal Bae, Somayeh Dodge
2021 Abstracts of the International Cartographic Association  
In this cartographic evaluation study, we assess how different static and dynamic geovisualization designs support participants' cognitive understanding of movement parameters such as speed and direction  ...  In addition, there is a great need for more empirical evaluation of how map displays are interpreted for trajectory and movement flow data (Davies et al., 2013; Dodge, 2020) , and how static and dynamic  ...

A Design Space of Vision Science Methods for Visualization Research [article]

Madison Elliott, Christine Nothelfer, Cindy Xiong, Danielle Szafir
2020 arXiv   pre-print
However, published visualization research currently reflects a limited set of available methods for understanding how people process visualized data.  ...  Researchers can use this design space to create innovative studies and progress scientific understanding of design choices and evaluations in visualization.  ...  This paradigm is well-suited to understanding how well viewers aggregate data across visualization types.  ...

User tasks for evaluation

Alexander Rind, Wolfgang Aigner, Markus Wagner, Silvia Miksch, Tim Lammarsch
2014 Proceedings of the Fifth Workshop on Beyond Time and Errors Novel Evaluation Methods for Visualization - BELIV '14  
User tasks play a pivotal role in evaluation throughout visualization design and development. However, the term 'task' is used ambiguously within the visualization community.  ...  In doing so, we identify a three-dimensional conceptual space of user tasks in visualization.  ...  [17] would all capture problems at a similar low composition level but at largely different levels of abstraction ranging from generic, to time-oriented data, to a concrete application domain.  ...

Visualizing Kanban Work: Towards an Individual Contributor View

Jeffrey S. Saltz
2019 Americas Conference on Information Systems  
The visualizations are then evaluated via a case study.  ...  Initial results suggest that the visualizations, which show the tasks done by week for each team member, were helpful in understand team member participation and that they were easy to understand and use  ...  We also plan to evaluate the tool within a software development context, to better understand how these results might be extrapolated to other domains.  ...
