A practical approach for recognition of hand gesture and distinction of its singularity

摘要

Recognition of the singularity such as the peculiarity or the inexpertness of the unskilled operator is necessary for safe operation. In this paper, based on the surface EMG signals, we propose a gesture recognition method and a novel distinction method of the singularity in operation. In order to evaluate the proposed gesture recognition and singularity distinction methods, experiments were carried out. In the experiment for gesture recognition, the recognition of 6 kinds of hand gestures of a wrist and a finger was performed. In the experiment for singularity distinction, assuming the peculiarity or the inexpertness of the operator, the same gesture was performed quickly as unusual operation, and unusual operation was distinguished from usual operation using the defined index of the singularity.
