Development of Myoelectric Prosthetic Hand Control System Using Mobile Terminal

Human fingers are indispensable to live. Prosthetic hands are often used for the reconstruction of the function of the fingers of upper limb amputees. There are many patients who wish to wear myoelectric prosthetic hands. However, it is not popular now in Japan. Hoshikawa et al. developed simplified myoelectric prosthetic hand as an easy-to-use one. However, it has problems with learning speed and scalability. In this research, Shadow System BLE was developed to solve the problem. This system can perform learning calculation and identification on a smartphone connected by Bluetooth Low Energy. We confirmed that it can perform learning calculation at high speed using abundant computing resources and can demonstrate the same identification rate as conventional system. Normally, since the smartphone is connected to the Internet, it is possible to use the server for identification or to use the Web API in the future.
