an empirical study on the usability of an information navigation aid
The Computer Aided Information Navigation (CAIN) project provides a method of adaptive navigation support that aims to increase the World Wide Web's value as a pedagogical tool. To examine whether the system's approach improves comprehension under specific conditions, an experiment compared CAIN with conventional web tools on three measures of performance: comprehension scores, task completion times and user satisfaction. Results revealed that comprehension scores were 30\% greater with CAIN than with the conventional tools and indicated that task completion times can also be reduced without compromising user satisfaction.
