This tutorial introduces adaptive hypermedia, a new area in human-computer interaction, focusing on systems that adapt hypermedia content to individual users. The tutorial is designed for an intermediate-level audience, including HCI researchers and practitioners interested in designing advanced hypermedia and web applications, as well as those interested in adaptive and intelligent interfaces. The aim is to provide a practical introduction to adaptive hypermedia, covering key concepts, efficient adaptation techniques, and their implementation on the World Wide Web. The tutorial begins with an overview of adaptive hypermedia (AH), explaining its purpose and potential applications. It then reviews existing application areas where AH can be useful, such as educational hypermedia, information retrieval, online help systems, and personal information spaces. The next sections discuss what can be adapted in AH, including content, links, and annotations, and present various adaptation techniques, such as conditional explanations, adaptive sorting, and hiding of links. The tutorial also explores the roles of users and systems in adaptation, the effectiveness of AH, and lessons learned from experimental studies. The final part of the tutorial focuses on implementing AH techniques in web-based systems, providing examples of adaptive annotation, hiding, and sorting of links, as well as developing adaptive hypermedia using CGI scripts and the MIT CL-HTTP server. The tutorial is intended to equip participants with the knowledge and skills to implement their own adaptive hypermedia systems. Peter Brusilovsky, the instructor, is a leading researcher in the field of adaptive hypermedia and has contributed extensively to the literature through numerous publications and reviews. The current tutorial is an updated version of a popular one presented at the ED-MEDIA'96 conference.This tutorial introduces adaptive hypermedia, a new area in human-computer interaction, focusing on systems that adapt hypermedia content to individual users.
