Real-time Analysis of Heart Rate Variability for a Mobile Human Emotion Recognition System
نویسندگان
چکیده
In this paper, we are focused on a mobile human emotion recognition system which is based on biosignal. Cardio signal is a proper bio-signal for emotion recognition and we use photoplethysmography (PPG) sensors to gather cardio signals. We mainly consider real-time heart rate variability (HRV) analysis which is essential to mobile emotion recognition. A mobile sensor module embedding a digital signal processor (DSP) is employed and we determine an appropriate method for fast Fourier transform (FFT) of cardio signals using those sensor module. Key-Words: emotion recognition, bio-signal, PPG, HRV, FFT, mobile, DSP

Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...

متن کاملA Predictive Model for Emotion Recognition Based on Individual Characteristics and Autonomic Changes
Introduction: The importance of individual differences in the problem of emotion recognition has been repeatedly stated in the studies. The major concentration of this study was the prediction of heart rate variability (HRV) changes due to affective stimuli from the subject characteristics. These features were age (A), gender (G), linguality (L), and sleep (S) information. In addition, the most...
