    Transmogrification: casual manipulation of visualizations.
    (ACM, 2013) Brosz, John; Nacenta, Miguel A.; Pusch, Richard; Carpendale, Sheelagh; Hurter, Christophe
    A transmogrifier is a novel interface that enables quick, on-the-fly graphic transformations. A region of a graphic can be specified by a shape and transformed into a destination shape with real-time, visual feedback. Both origin and destination shapes can be circles, quadrilaterals or arbitrary shapes defined through touch. Transmogrifiers are flexible, fast and simple to create and invite use in casual InfoVis scenarios, opening the door to alternative ways of exploring and displaying existing visualizations (e.g., rectifying routes or rivers in maps), and enabling free-form prototyping of new visualizations (e.g., lenses).

    When Paper Meets Multi-Touch: A Study of Multi-Modal Interactions in Air Traffic Control
    (Springer, 2013) Savery, Cheryl; Hurter, Christophe; Lesbordes, Remi; Cordeil, Maxime; Graham, T.C. Nicholas
    For expert interfaces, it is not obvious whether providing multiple modes of interaction, each tuned to different sub-tasks, leads to a better user experience than providing a more limited set. In this paper, we investigate this question in the context of air traffic control. We present and analyze an augmented flight strip board offering several forms of interaction, including touch, digital pen and physical paper objects. We explore the technical challenges of adding finger detection to such a flight strip board and evaluate how expert air traffic controllers interact with the resulting system. We find that users are able to quickly adapt to the wide range of offered modalities. Users were not overburden by the choice of different modalities, and did not find it difficult to determine the appropriate modality to use for each interaction.
