Abstract
In the development of real-time Web games, tuning such as synchronization control and transmission interval considering the influence of network delay requires knowledge and experience. Therefore, reducing the time required for learning and trial and error for development is an issue. In this study, the authors developed a QoE assessment based on users' objective factors in order to reduce the time required for tuning during game development. Specifically, the authors have developed a QoE assessment by analyzing EEG and log data from a subject experiment in several combination patterns of network delay and tuning parameters by using a developed 2D game.
