The convenience and intelligence of devices should create easiness and flexibility for users. Artificial devices require interdisciplinary collaboration from neurosurgeons, surgical surgeons, physiotherapists and equipment development. Computer engineering plays a crucial role in the design step, supporting manufacturing, training and recognition to match the desirability of customers. Moreover, users need a wide rangeof different options such as an aesthetic functionalmaterial, amyoelectricmechanism, a body-powered appliance or an activity specified device. Thus, the flexible configuration, the proper features and the cost are some important factors that drive user's selection to the prosthesis. In this article, wedescribe an effective andpowerful solution for analyzing, designinghardware and implementing software to train and recognize hand gestures for prosthetic arms. Moreover, we provide evaluation data of themethod comparedwith similar approaches to support our design and implementation. This is fairly a complete system, making it a convenient solution for hand-cutoff people to control prosthetic hands using their electromyography signals. Statistical resultswith evaluations show that the device can respond correspondingly and the method creates promisingly recognition data after correct training processes. The prosthetic hardware implementation has also been simulated using a Light-emitting diode (LED) hand model with a high accuracy result.
