In this paper, we propose a serious game which aims to draw the interest of rehabilitants and increase their locomotive ability with an infrared ray(IR) pen interface. The proposed game focuses on providing easy-to-manipulate cognitive rehabilitation environments. In order to achieve the goal, we devised new game interface composed of a Wiimote controller and a IR pen. Moreover, SVM(support vector machine) algorithm was employed for gesture recognition. The proposed game can be successfully utilized not only for rehabilitants but also for aged persons in preventing dementia and promoting their health.
