Computer-mediated learning systems: a new perspective

Software applications continue to increase in both power and complexity. The role of help systems, software guides and tutorials (or, collectively, computer-mediated learning) becomes ever more important in overcoming the complexity barriers. Unfortunately, the majority of existing guidance systems are wholly inadequate. Most are cumbersome to use and rarely provide the answers the user is looking for. This article presents the findings of a project that set out to redefine the current state of CML. The project was named Aptus. The essence of any CML system can be captured by the criteria of "asking the question" and "giving the answer". Aptus improves on "asking the question" by introducing natural language querying and free text searching, together with structured contextual browsing to the CML document. Aptus improves on "giving the answer" by introducing clarity and diversity of media. The net result is a considerably more helpful and usable CML system, that has proved to be quicker, easier and more accurate for users.
