Abstract

In this paper, algorithms for multivariate data projection, based on topology or distance preserving mappings, as well as tools and techniques for projection display and user interaction are briefly reviewed and compared in an unifying approach. Advanced mapping algorithms, that focuse on improved data structure preservation, following laws of perception as given by Gestalt-theory, as well as advanced features of data visualisation and navigation are introduced. These methods help to exploit the remarkable human perceiptive and associative capabilities in man/computer dialog, e.g. for visual exploratory data analysis.
