这项研究的目标是利用光学传感器开发一种直观的可穿戴人机界面(HMI)。所提出的系统使用光学位移传感器来量化手腕旋前和旋后。与现有系统相比，这种人机界面依赖于前臂位置的直接测量来确保直观性，最大限度地减少了涉及的传感器，预计将是持久的。为了测试可行性，开发的人机界面被实施来控制基于健康受试者前臂旋转的假肢手腕。对6名身体健全的个体，使用衣夹重新定位任务，比较了光学传感器系统(OSS)假体控制和基于肌电(EMG)的直接控制的性能。结果表明，OSS控制的性能与直接控制相当，从而验证了OSS人机界面的可行性。
The goal of this research was to develop an intuitive wearable human-machine interface (HMI), utilizing an optical sensor. The proposed system quantifies wrist pronation and supination using an optical displacement sensor. Compared with existing systems, this HMI ensures intuitiveness by relying on direct measurement of forearm position, minimizes involved sensors, and is expected to be long-lasting. To test for feasibility, the developed HMI was implemented to control a prosthetic wrist based on forearm rotation of able-bodied subjects. Performance of optical sensor system (OSS) prosthesis control was compared to electromyography (EMG) based direct control, for six able-bodied individuals, using a clothespin relocation task. Results showed that the performance of OSS control was comparable to direct control, therefore validating the feasibility of the OSS HMI.
