Pad: An Alternative Approach to the Computer Interface; with David Fox, 1993 Computer Graphics (proceedings of ACM SIGGRAPH Conference); Vol. 26 No. 3.

This paper describes a spatial metaphor for computer interface design, providing an intuitive base for the support of such applications as electronic marketplaces, information services, and on-line collaboration. Pad is an infinite two dimensional information plane that is shared among users, much as a network file system is shared. occupies a well defined region on the Pad surface. We describe the Pad interface, we discuss how to efficiently implement its graphical aspects, and we illustrate some representative applications.


A New Scheme for Drawing Hypergraphs; with M.V. Kritz, vol. 49 no. 1+2 of the International J. of Computer Mathematics

A ``hypergraph'' over a set S is a graph whose nodes are subsets of S. Visualizing hypergraphs has always been problematic. We describe a fundamentally new scheme to visualize and interact with hypergraphs, based on a dynamic multiscale representation.
