    Heart rate variability and respiratory sinus arrhythmia assessment of affective states by bivariate autoregressive spectral analysis by Magagnin, Valentina, Mauri, Maurizio, Cipresso, Pietro, Mainardi, Luca, Brown, Emery N., Cerutti, Sergio, Villamira, Marco, Barbieri, Riccardo

    Published 2012
    “…The study of emotions elicited by human-computer interactions is a promising field that could lead to the identification of specific patterns of affective states. We present a heart rate variability (HRV) assessment of the autonomic nervous system (ANS) response and respiratory sinus arrhythmia during PC-mediated stimuli by means of standard and multivariate autoregressive spectral methods. 35 healthy volunteers were exposed to computer-mediated tasks during data collection. …”
