Effective e-learning by use of HCI and web-based workflow approach

A web-based workflow system is proposed to help users study by e-learning anywhere and anytime. Basically, the Workflow based e-Learning System is a learning environment supported by workflow technology which provides a flexible learning solution. With the rapid development of Internet, distance-learning applications over Internet become more and more popular. The user interface of a system is often the yardstick by which the system is judged. An interface which is difficult to use will, at best, provide result with a high level of user errors. At worst, it will cause the software system to discard, irrespective of its functionality. If the information is presented in a confusing or misleading way, the user may misunderstand the meaning of an item of information. They may initiate a sequence of unexpected actions which even cause the system failure. In this respect, this paper focuses on the design principles and implementation of the Human-Computer Interface(HCI). We lay down the guideline for HCI design concept and principles, and evaluate the HCI design of a Workflow-based e-Learning application.
