Hook: Evaluating the Utility and Usability of an Adaptive Hypermedia System

by Carson Reynolds

Hook presents an adaptive hypermedia system which works by expanding and collapsing various information entities when particular task behaviors are detected.

In this article, we see an important reoccurring point namely, that users must be in control of adaptive systems. Basically, any adaptations must have access to the full space of interaction. The adaptation should aslo be invertable by the user.

Evaluations of adaptive systems usually are done relative a static system. A common criticism is that the static system is hobbled without the adaptive facilities.

Hook’s study of 9 participants using static and adaptive interfaces found that the adaptive system led to fewer actions on the user’s part, and that users subjectively preferred the adaptive interface.
