3/72.2.3 Hypermedia and CAI
Hypermedia will be treated in detail later in this thesis. Both ``hypertext'' and ``multimedia'' changed and enriched CAI enormously. Originally CAI systems were linear, i.e. the frames were ordered in a sequential order, which often led to the so called ``tunnel syndrome''. Also, people became bored by watching one frame after the other. However, the hyperlink paradigm allowed users to navigate fairly freely within a certain instructional domain. Actively exploring the learning material in this manner can make using CAI programs much more exiting and fun for the user.The first CAI systems effectively were all text-based, and it is very difficult to present learning material in a text-based program, while ensuring that the application remains user friendly. Multimedia opened a new era for CAI software. Images, audio, video and animations enriched tutoring systems and made them more efficient. On the one hand it became possible to present the learning material more effectively (``A picture is worth a hundred words''). On the other hand you could design your program much better using metaphors like virtual rooms etc. However, CAI is still very difficult to produce and maintain, especially the TV quality graphics which most students are now used to (see section 2.3.4).
