Building an experimental system to examine a method for supporting verbal explanation

In the future digital textbooks, a new media is desired to support verbal explanation of subjective knowledge. In this study, we used the scenario of conveying pottery skill as an example to explore a practical method for passing subjective knowledge. We proposed a method and built a prototype system to support verbal explanation of the feeling or sense of force, which is essential in explaining pottery skills. In the system, a force feedback device was integrated. Preliminary experimental results indicate that the method is feasible and can be integrated with a digital textbook.
