DEVELOPMENT OF AN AUGMENTED REALITY-ORIENTED GAME SYSTEM FOR STROKE REHABILITATION ASSESSMENT

In this paper, rehabilitation tools are proposed and implemented to assist patients with stroke and body dysfunction via auxiliary physical activity. By integrating the entertainment of games and the needs of rehabilitation and utilizing motor assessment scale (MAS) as the building blocks, we propose a game system developed for assessment of stroke rehabilitation by using augmented reality (AR) technology. By means of application of AR Markers and based on related parameters of Wii remotes, various assessment games have been implemented, and vivid pictures can be presented to users via a head-mounted display by seamless combination of real environment and virtual objects. This game system takes various assessment scales into consideration, and each scale is specifically designed and individually integrated to enable the relevant capacity for assessment of motor functions. According to the experimental results, the accuracy rate of the users in successfully following the game steps is 91.2%, and the accuracy rate of the system in assessing the MAS categories is as high as 94.6%, which confirms the feasibility of our proposed and implemented rehabilitation game system.
