Quantifying the Rating Performance of Ambiguous and Unambiguous Facial Expression Perceptions Under Conditions of Stress by Using Wearable Sensors

Popis výsledku v původním jazyce

Background: In real-world scenarios humans perceive the world contextually,relying on previous information to modify their responses. During interactionswith a machine, missing contexts may decrease the accuracy of judgements.In the realm of human-computer interactions (HCI), relatively easy tasksas controls may not be relevant.To evaluate the impact of stress we increased the cortisol level by the safe butreliable procedure Cold Pressor Task. We used five stimuli represented by facialexpressions: &apos;neutral&apos;, &apos;laughter&apos;, &apos;fear&apos;, &apos;pain&apos;, and &apos;pleasure&apos;.Aim: We intend to find out how the responses to stimuli are altered by stressand statistically quantify the BVP (Blood Volume Pulse) signals.Materials: 27 raters rated these five stimuli presented by 5 actors and 5actresses, while BVP was being registered.Methods: Each physiological response was a six-second time series after therater rated the stimulus. A nontrivial model includes lag dependencies on eitherprevious states or previous noise. The simplest models would be ARMA(p, q)models with to-be-determined parameters ϕ1, . . . ϕp and θ1, . . . θq.Inferences: In this study, we find that the wearables&apos; sampling for six secondscannot separate signal from noise significantly. Only one response was found tobe significantly affected by the condition of stress: the perception of fear.
