Abstract:

The Hypertext Functionality field studies techniques for and the impact of supplementing everyday computer applications with hypertext (or hypermedia) functionality (HTF). The HTF approach encourages system developers to think actively about an application's interrelationships, and whether users should access and navigate along these relationships directly. It views hypertext as value-added support functionality. The HTF approach fosters three major areas of research: using HTF to improve personal and organizational effectiveness, HTF and application design,and integrating HTF into applications.
