To develop a hand rehabilitation device, the patient-specific heterogeneity of physical ailments must be considered in the design process to provide optimized rehabilitation. In this paper, we suggest a low-cost customized manufacturing process of a hand rehabilitation system. We first extract the length and size of the fingers based on a CMOS camera system. Then, the mechanical components of the rehabilitation system were manufactured using a 3D printer. User safety is guaranteed using a simple operation range control connector mechanism which mechanically locks up when the range of motion of each finger is exceeded for finger extension. We verified the usability of the hand rehabilitation system and applied the system to two custom interactive video games.

基于交互式游戏的镜像手部康复系统的开发

要开发一种手部康复设备，必须在设计过程中考虑患者特定身体不适的异质性，以提供最佳的康复效果。在本文中，我们建议一种低成本的手部康复系统定制制造工艺。我们首先基于CMOS摄像头系统提取手指的长度和大小。然后，使用3D打印机制造康复系统的机械组件。简单的操作范围控制连接器机制可确保用户安全，当手指伸出时超出每个手指的运动范围时，该机制将机械锁定。我们验证了手部康复系统的可用性，并将该系统应用于两个定制的交互式视频游戏。
