AxiSketcher: Interactive Nonlinear Axis Mapping of Visualizations through User Drawings

Abstract Visual analytics techniques help users explore high-dimensional data. However, it is often challenging for users to express their domain knowledge in order to steer the underlying data model, especially when they have little attribute-level knowledge. Furthermore, users’ complex, high-level domain knowledge, compared to low-level attributes, posits even greater challenges. To overcome these challenges, [...]

Beyond Usability and Performance: A Review of User Experience-focused Evaluation Goals in Visualization

Abstract Traditionally, studies of data visualization techniques and systems have evaluated visualizations with respect to usability goals such as effectiveness and efficiency. These studies assess performancerelated metrics such as time and correctness of participants completing analytic tasks. Alternatively, several studies in InfoVis recently have evaluated visualizations by investigating user experience goals [...]

Visualization by Demonstration: An Interaction Paradigm for Visual Data Exploration

Abstract Although data visualization tools continue to improve, during the data exploration process many of them require users to manually specify visualization techniques, mappings, and parameters. In response, we present the Visualization by Demonstration paradigm, a novel interaction method for visual data exploration. A system which adopts this paradigm allows users to [...]

InterAxis: Steering Scatterplot Axes via Observation-Level Interaction

Short explanation of the figure above. Abstract Scatterplots are effective visualization techniques for multidimensional data that use two (or three) axes to visualize data items as a point at its corresponding x and y Cartesian coordinates. Typically, each axis is bound to a single data attribute. Inter- active exploration occurs by [...]
