We developed a role-playing library system to serve this purpose. A survey of 2377 Chinese users was done. A theoretical model of emotion-driven learning (ELM) was proposed based on the analysis results of valid recovered data. Additionally, NPCs were found to be effective in improving learning outcomes through emotional support. An interactive education system may be able to enhance the perceived playfulness of learning in order to enhance the learning experience.
