Large multi-touch displays are expanding the possibilities of multiple-coordinated views by allowing multiple people to interact with data in concert or independently. We present Lark, a system that facilitates the coordination of interactions with information visualizations on shared digital workspaces. We focus on supporting this coordination according to(More)
Tabletop displays with touch-based input provide many powerful affordances for directly manipulating and collaborating around information visualizations. However, these devices also introduce several challenges for interaction designers, including discrepancies among the resolutions of the visualization, the tabletop's display, and its sensing technologies;(More)
We present a case study of an interactive, multiple heterogeneous-display, multi-touch visualization for informal science education. Our visual simulation application, called WALDEN, has been developed using a Microsoft Surface and a large data wall. Multiple displays offer users the opportunity to interact with large visual datasets and observe complex(More)
