Governments around the world are interested in public safety services for protecting the public from violent crimes. For the public safety services, a technology for detecting violent activities attracts attentions. This paper proposes an analysis method for analyzing punches by using fast Fourier transform (FFT) and long short-term memory (LSTM) of accelerometer and gyroscope data of wearable devices. The proposed method analyzed characteristics of accelerometer data in frequency domain by using FFT. The proposed method achieves 97.27% accuracy and 97.27% F1-score for classifying types of punches (e.g., left hook, left jab, right cross, and right hook) by using LSTM. The proposed method will contribute to detect violent activities and thus will help fast response to the violent crimes.
