Object-centric temporal navigation for dynamic information visualizations.
… temporal navigation for time-varying information visualizations. In our approach, navigation through time is controlled by interacting directly with any data item, enabling simultaneous exploration of the time dimension while focusing on the changing item. Subtle visualizations of a …

A web-based, run-time extensible architecture for interactive visualization and exploration of diverse data
Information visualizations must often be custom programmed to support complex user tasks and database schemas. This is an expensive and time consuming effort, even when general-purpose visualizations are utilized within the solution. This research introduces the Snap visualization server and system …

Information visualization as creative nonfiction
Information visualizations are an important means through which we communicate knowledge. By considering visualizations as data-driven narratives, this thesis uses narrative thinking as an orienting concept to support the production and evaluation of information visualizations. It proposes a set of …

Visualization Schemas: A User Interface Extending Relational Data Schemas for Flexible, Multiple-View Visualization of Diverse Databases
Information visualizations utilizing multiple coordinated views allow users to rapidly explore complex data spaces and discover complex relationships. Most multiple-view visualizations are static with regard to the views that they provide and the coordinations that they support. Despite significant …

Effects of Large, High-Resolution Displays for Geospatial Information Visualization
Geospatial visualizations are becoming a larger part of society. From using maps to go from one location to another to using battlefield visualizations to help the military, geospatial visualizations are becoming a larger part of people's lives. At the same time, large displays are becoming more …

The Visual Scalability of Integrated and Multiple View Visualizations for Large, High Resolution Displays
… integrating spatial and multidimensional data. Information visualizations are often used to aid these scientists, but designing the visualizations is challenging. One aspect of the visualization design space is a choice of when to use a single complex integrated view and when to use multiple …

Implicit gaze interaction for information visualization
… to ease object selection in crowded regions of information visualizations.

Transforming big data into knowledge : experimental techniques in dynamic visualization
Information visualizations, especially those utilizing web-based platforms, are becoming an increasingly common medium for exchanging ideas. This emergent class of tools enabling web-based, interactive platforms for visualizing data should be considered by urban planners and designers as an …

From data to knowledge: Tableau dashboards as boundary objects in the knowledge ecology of a university
Information dashboards are increasingly important tools for organisations, helping them exploit data as an asset and make informed decisions. Existing visualisation design research stemming from the cognitive and perception sciences has tended to focus on the cognitive augmenting benefits of …

Visual encoding quality and scalability in information visualization
Information visualization seeks to amplify cognition through interactive visual representations of data. It comprises human processes, such as perception and cognition, and computer processes, such as visual encoding. Visual encoding consists in mapping data variables to visual variables, and its …

Computational understanding of image memorability
… generalize to an applied visual modality - information visualizations. We separately find that intrinsic differences are already present shortly after encoding and remain apparent over time. Second, we consider two extrinsic factors: image context and observer behavior. We measure the …

Saliency in audio and visual signals
… saliency in signals containing temporal information such as image sequences. In this dissertation, we propose a new saliency framework based on outlierness of the center region comparing to the surround region. Specifically, the surround region is divided into several subregions and the …

Towards exploratory faceted search systems
… search system, but with the added ingredients of information visualizations and query-by-example. To illustrate our ideas we have built two freely available web applications. The first one, Biomed Search, has been positively received by the community and offers some novel characteristics. First, …

ICoN: Immersive Computational Notebook for Data Science
… interface that integrates code, documentation, visualizations, and data within a single environment. However, as data analysis becomes increasingly complex, the traditional WIMP (Windows, Icons, Menus, Pointers) interface faces limitations in supporting advanced, embodied workflows. To address …
