Spectral methods are naturally suited for dynamic graph layout, because moderate changes of a graph yield moderate changes of the layout under weak assumptions. We discuss some gen...
This work discusses the effectiveness of desktop virtual reality as a metaphor for navigating through information in structured Web sites. The work is based on a model for informa...
In this article we analyze the problem of searching the WWW, giving some insight and models to understand its complexity. Then we survey the two main current techniques used to se...
In this paper we present the use of "what-if"-analysis in simulation games for spatial decision making by introducing the concept of multiple worlds. We expect that &quo...
Building on the work of games theorists and virtual world designers, this paper proposes a framework for understanding the real-virtual dichotomy in terms of a series of five fram...
