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)
—We consider the problem of developing colour sequences that offer the best dynamic range when used for pseudo-colouring. We began with nine colour sequences currently suggested for visualization and informally compared them to discover which was subjectively seen to have the most pleasing visual aesthetic. This comparison indicated that different colour(More)
Fig. 1. Groups of people engaging in information exploration and analysis in work (left) and public settings (right). Abstract— Digital tabletop displays and other large interactive displays have recently become more affordable and commonplace. Due to their benefits for supporting collaborative work—when compared to current desktop-based setups—they will(More)
Given common search interfaces, it is difficult to gain orientation within large information spaces and explore information along conceptual dimensions such as time, location, and topics. In this thesis, I develop the idea of visual information exploration on the Web (VIEW) that aims to support a more active way of finding and exploring information by the(More)
