Design and Implementation of Adaptive Neuro-fuzzy Exergame Controller
Introduction: Due to sedentary postures caused by video games, many health-related issues have occurred among players. One practical solution for dealing with the aforementioned problem is to come up with game controllers which promote physical exercises. In this study, an adaptive neuro-fuzzy exerg...

Conclusion: In the proposed method, the FLS was fine-tuned by gathering data from the user, which improved the performance of the controller due to the fact that the controller was trained to best suit the needs of the user. The gathered data was then used to change the parameters of the FLS to provide an acceptable playing experience for the user.http://jrrs.mui.ac.ir/index.php/jrrs/article/view/3448neuro-fuzzy logic systemadaptive systemexergamesgame controller |
