User interface in virtual learning environment

Designing user interface has special importance in virtual learning. Considerable portion of students' time is spent in attempting to learn system, work with present lists in user interface and so forth. Perhaps virtual education system has several computational powers, but it lacks adequate user interface. Then, using system would be difficult and user may encounter many confuses during the work and would be unsuccessful in reaching their goals. These are results of unfamiliarity with fundamental principles and in user interface design and disusing them in generating virtual learning systems. Thus, in any virtual learning system design, it is necessary to consider fundamental principles and rules of the user interface design in such system, and in this manner, in this research an adequate user interface is suggested for e-learning environment in which has been evaluated with regard to these fundamental principles and rules. Evaluations have been done on this interface show its desirable ability to attract users' satisfaction.
