Navigational Tools in Hypertext Information Retrieval Frames and an Expandable Table of Contents

Abstract

Difficulties with navigation are common in hypertext documents. Many studies have examined techniques and design strategies to find the proper structure of a hyperdocument whereas others have investigated navigational tools such as overview diagrams, maps, menus, and/or tables of contents that help users navigate through complex hyperdocuments. This study has investigated the effects of table of contents and frames as user interface on user performance and user satisfaction. The result suggests several guidelines for designing complex hypertext information retrieval systems and creating on-line documentation.
