Trade-off between Model Capacity and Controllability in Realtime Myoelectric Control

Kurzfassung

The loss of the upper limbs can bring severe inequality in daily life, influencing the social and mental state of the subject. Thus, early developments in body-driven prostheses date centuries ago and they have been developing ever since. During 1950s, rapid developments in technology resulted in powered myoelectric hand prosthetics. Myocontrol consists of defining control commands for a self-powered prosthetic device using decoded signals originating from the muscle fibres of the amputated subject. This conversion should be as natural and swiftly as possible and make use of a non-invasive interface between the subject and the device. The aim of this report is to present the state of the art of the myocontrol technology developed until today. We will then briefly introduce the hardware we will use and the possible strategies we will follow.
