Learning using information and communication technologies, such as remote experiments and e-learning systems, is effective in engineering education. However, most of the existing systems providing these learning materials cannot be used with smartphones. In order to overcome the problem, the authors have developed an educational support system that can be used with smartphones by using HTML5 for building client-side applications of the system. Using the system, students can use interactive 3DCG based learning materials to learn about a DC motor and an alternator and conduct remote experiments on the motor and the alternator. In addition, the authors conducted a survey to evaluate the system, and it turned out that the system was accepted by the students as a useful tool.
