Abstract:
In this investigation various human emotional reactions are jointly represented as a multidimensional dynamic system. Within consensual, componential paradigm, emotions being understood as perceptual, physiological, and behavioral responses to personally relevant events. Presented study considers emotional multimodal dynamic system, given different types of emotion-evoking stimuli connected to individual multifaceted response patterns. In order to model the multimodal interaction between bio-signals and corresponding emotion expressions, professional actors had been utilized in the study to accurately record various physiological patterns. A novel nonparametric deconvolution scheme had been employed for extrapolation towards desired excessive emotional levels. The primary advantage of a nonparametric extrapolation scheme over existing parametric ones lies within its additional numerical accuracy and stability. The primary objective of this investigation was to benchmark the novel multimodal bio-reliability and risk/hazard assessment methodology, based on sensor-recorded emotional data. Presented study advocates state-of-the-art multivariate Gaidai reliability approach, enabling prognostics of human errors, as well as Health, Safety, and Environment (HSE) concerns, connected to excessive human emotions in a variety of sectors. Due to the multimodal reliability methodology's generic character, its use in no way restricted by the examined case study. RESULTS: showed that Piezoelectric respiration (PZT) readings differed best across all five studied emotional states, the PZT sensor results exhibited best performance in capturing differences across both valence and arousal emotional states.
