Using Overlays to Support Collaborative Interaction with Display Walls

Large-scale display walls, and the high-resolution visualizations they support, promise to become ubiquitous. Natural interaction with them, especially in collaborative environments, is increasingly important and yet remains an on-going challenge. Part of the problem is a resolution mismatch between low-resolution input devices and high-resolution display walls. In addition, enabling concurrent use by multiple users is difficult. In this paper, we present an overlay interface element superimposed on wall-display applications to help constrain interaction, focus attention on subsections of a display wall, and facilitate collaborative multi-user workflow.
