Abstract

New approaches and tools are required to inform the design and implementation of 3-dimensional (3-D) digital cities and to steer the growth of their virtual communities. This paper argues to apply information visualization techniques and to utilize Twin Worlds - pairs of virtual worlds in which one world is devoted to visualize user interaction data collected in the other world - to augment, evaluate, and research the digital cities of tomorrow. The approach is exemplified by means of an abstract scholarly digital city: A 3-D collaborative Memory Palace - a shared resource of online documents (web pages, papers, images, videos, software demos) for faculty and students at the School of Library and Information Science at Indiana University - and its twin, Mirror Garden - a second 3-D world that visualizes user interaction data collected in the Memory Palace.
