“Mumai is an open-source muscle-machine interface that connects your body to any kind of electronic or mechanic device through the myoelectric (EMG) signals generated by your muscles. The uses of this interface are limited only by your imagination. It can be used to control assistive robotic devices such as prostheses or exoskeletons. Alongside some of the freely available machine learning libraries (Scikit-learn, TensorFlow, Dlib…) it can be used to implement a gesture recognition controller to interact with electronic devices such as computers or smartphones. In the sports field, it can be used to optimize the level of exercising. At a university level, it can be used in biosignal processing courses, working as a biomedical instrumentation device. How this device will be used depends on you.”
