Description

The purpose of this paper is to show a method for the objective detection of human laughter by electromyography (EMG). In order to discriminate the human laughter from the other body movements, we compare the each of EMG data collection from the abdominal surface by frequency analysis. We find that the myoelectric signals in human laughter have periodic repetitions of 4-6Hz. This distinctive feature of human laughter enables us to distinguish it from the other body movements. Our results are of importance in the objective and quantitative measurement of the human laughter.
