Interactivity Factors in Visualization-Based Exploratory Search

Designing interactive visualizations is challenging, especially in complex, open-ended contexts. Although numerous interaction techniques have been developed, there is a lack of holistic theoretical guidance in the visualization literature on designing interactivity, where interactivity refers to the overall quality of interaction between a user and a visualization tool. In this work, we aim to contribute to a deeper understanding of the design and evaluation of interactivity by exploring user perceptions in an exploratory context. We report the findings of a lab study and reflect on its potential implications for visualization designers and researchers.
