ID2 – A Scalable and Flexible Mixed-Media Information Visualization System for Public Learning Exhibits

This paper describes an innovative, mixed-media information visualization display method and system architecture for public learning exhibits. The system is scalable in the number and types of displays and flexible in its applicability to a range of data domains and interaction models. This work extends and improves the original illuminated diagram paradigm which merges static, ultra-resolution, hardcopy prints with dynamic, lower-resolution, softcopy graphics. In this paradigm, projected graphics are used to highlight relationships among the detailed information in the hardcopy prints. Multiple coordinated views enable the comparison of data between reference systems, and interactive queries employ brushing and linking methods to synchronize highlighted information between views. This system is applicable to any information visualization display where multiple, static reference maps can be used in unison to improve the exploration and understanding of very large data sets.
