SEARCH BY CITATION

Abstract

The Internet is a medium for education, entertainment, communication, and personal expression. User behavior has developed three main modalities for using this medium effectively—searching, browsing, and monitoring—which are supported to different degrees by conventional tools. Understanding the nature of the interaction allows us to design and implement a system called Mitsukeru to support browsing behaviors, while retaining the free-form movements between other interaction styles. The system uses agent-based modeling and look-ahead to provide informative yet nonintrusive guidance to the user, and is described in detail.
