    Reflections on an Experiment, Evaluating the Impact of Spatialisation on Exploration
    (The Eurographics Association, 2017) Roux, Clement; McAuley, John; Barbora Kozlikova and Tobias Schreck and Thomas Wischgoll
    This paper reports on an experiment designed to evaluate whether visualising a digital library (using a spatialisation technique) can influence exploratory search behaviour. In the experiment we asked participants to complete a set of novel tasks using one of two interfaces - a visualisation interface, ExploViz, and its search-based equivalent, LibSearch. A set of measures were used to capture sensemaking and exploratory behaviour and to analyse cognitive load. As results were non-significant, we reflect upon the design of the experiment, consider possible issues and suggest how these could be addressed in future iterations.

    TexTile: A Pixel-Based Focus+Context Tool For Analyzing Variants Across Multiple Text Scales
    (The Eurographics Association, 2017) Asokarajan, Bharathi; Etemadpour, Ronak; Abbas, June; Huskey, Sam; Weaver, Chris; Barbora Kozlikova and Tobias Schreck and Thomas Wischgoll
    Before the advent of printed texts, text duplication was done primarily by hand. Errors, alterations, and erasures were common and varied widely across different copies of the same text. Classics scholars seek to reconstruct an ''original'' text by analyzing and merging variations across copies as ''witnesses'' to a conjectured original. Many scholars continue to use spreadsheets, sometimes as large sheets of actual paper, to visually collate variations across known versions. These approaches are generally well suited for collection of data about variations, a process that can take decades. However, they are poorly suited for analysis of variation above the level of individual words. Visualization techniques are needed to reveal patterns of variation at the level of lines, pages, and entire texts. We present TexTile, a new tool that integrates pixel-based and focus+context visualization techniques for analysis of reconstructed classical Latin texts. TexTile provides a comprehensive yet compact representation of variation at multiple levels over an entire text. The tool helps scholars validate the accuracy of textual variants and analyze similarities between different contributing copies. The integrated visualization design allows exploration of variation across textual scales while preserving continuity of browsing, much like when examining a physical manuscript. We conducted a mixed quantitative-qualitative user study to assess the usability of the integrated design.

    Visualizing Large Time-series Data on Very Small Screens
    (The Eurographics Association, 2017) Chen, Yang; Barbora Kozlikova and Tobias Schreck and Thomas Wischgoll
    In this paper, we present a space-efficient visualization and an interaction technique for exploring time-series data on very small screens. The visualization is based on a simultaneous display of contextual visualization in the display border and focused interfaces in the center region of displays. The interaction technique utilizes fisheye distortion to facilitate data selection and navigation interactions in the contextual visualization. The proposed techniques could benefit a wide range of analysis applications on wearable devices. Two applications are highlighted to demonstrate the usefulness of the techniques.
