![]() It has been suggested that staggering may reduce occlusion, while also reducing display complexity and producing less overwhelming animations, though no empirical evidence has demonstrated these advantages. One major factor is whether the animation relies on staggering-an incremental delay in start times across the moving elements. There are multiple animation techniques to choose from, and it is not always clear which should produce the best visual correspondences between display elements. Interactive visual applications often rely on animation to transition from one display state to another. We investigate its usability, provide preliminary evidence for the effectiveness of this technique through metric evaluations and user study and discuss limitations and future directions. The technique is flexible and simple to implement, and has the additional advantage that it explicitly enhances coordinated motion and can avoid crowding, which are both important factors to help users track moving objects in a scene. In this paper, we introduce animated transition design, a technique to build smooth, non-linear transitions for clustered data with either a minimal amount of user interaction or totally free of user involvement. ![]() Current research in animated transitions has mostly focused on linear transitions (all elements follow straight line paths) or enhancing coordinated motion through bundling of linear trajectories. This is especially true if data elements cannot be visually distinguished by other means. We then introduce a design space that allows a holistic characterization of stagedanimation and propose an authoring tool to support the prototyping and exploration of stagingin visualizations.Īnimated transitions can be effective in explaining and exploring a small number of visualizations where there are drastic changes in the scene over a short interval of time. Through an empirical study, we investigatethe meaning of the Common Fate Law, applied on animation trajectories, in dynamic visual-izations. We discuss the main challenges for designing andevaluating animation in dynamic visualizations. We then present the theoretical fundamentals foranimation in information visualization. ![]() We first provide a structured view of the roles anddrawbacks of animation in user interfaces. Prior research have also predominantly assessedthe value of animation through a narrow empirical angle, which had left several facets ofanimation unveiled.This thesis contributes a first constructive step toward better understanding the vast designspace of animation and mapping out the various merits of animation that can enrich userinterfaces from different perspectives. While prior research and practice provide usefulinsights about the merits and downsides of animation, it is still unclear what makes a goodand effective animation that improves the usability and expressivity of graphical interfaces.The disparity of opinions about the value of animation is mainly due to the fact that most ofprevious studies have investigated the benefit of adding a particular animation to a particularinterface, leaving a notable gap in the deep understanding of the many design aspects thatinfluence the performance of animation. Despite their increasing popularity and omnipresence in modern graphical interfaces, anima-tions are still largely under-comprehended.
