Learning styles for e-learning systems over virtual desktop infrastructure

By introducing the technology of the virtual desktop infrastructure (VDI) to e-learning systems, the identical learning environment can be??provided to the learner at any time, and at any place, and also even if the learner stops learning or working, he can restart it by different terminals including different operating systems. On the other hand, the quality of screen images on the desktop would be affected by the quality of service (QoS) of the network, since the screen images are transferred to the client from the server by their transfer protocol. In this paper, we discuss the influence of the QoS upon the learning styles caused by the usability over the VDI. By constructing the experimental network using network emulators, we evaluate and discuss the influence of the QoS such as a round trip delay time (DT) and a bandwidth (BW) upon learning style measured by the quality of experience (QoE). As a result, we clarify the relationships between the QoS of the network and the QoE of the e-learning styles.
