Distance education system with visualized atmosphere information based on fuzzy inference

A distance education system is designed based on fuzzy inference, where visualized atmosphere information is shared by all learners in a virtual classroom. It provides high aspirations, low isolated feeling, low stress, and high affinity to learners, and offers learner's psychological information, individual difference information, and hints of system improvement to system manager. The effect of visualized atmosphere information to learner's psychological states is confirmed by T score Anger-Hostility (A-H) of POMS test for 15 graduate students using CAI contents, and comparison experiment with traditional distance education in terms of paired t-test obtains p-value 0.011 of A-H. The proposal of atmosphere information presentation of virtual classroom provides a first step of establishing over face-to-face distance education system.
