Summary

Successful use of information and communication technologies depends on usable designs that do not require expensive training, accommodate the needs of diverse users and are low cost. There is a growing demand and increasing pressure for adopting innovative approaches to the design and delivery of education, hence, the use of online learning (also called E-learning) as a mode of study. This is partly due to the increasing number of learners and the limited resources available to meet a wide range of various needs, backgrounds, expectations, skills, levels, ages, abilities and disabilities. The advances of new technology and communications (WWW, Human Computer Interaction and Multimedia) have made it possible to reach out to a bigger audience around the globe. By focusing on the issues that have impact on the usability of online learning programs and their implementation, this specifically fills-in a gap in this area, which is particularly invaluable to practitioners.
