Abstract

 

In the actual sense, the skin tells us a lot about our emotions, our skin gives out a alot of information about what we feel and responds to stimuli when exposed to emotionally loaded stimuli in form of video content, images, events, and other kinds of stimuli. They give positive and negative emotions depending on what we are involved in. We are automatically psyched up or surprised during stress and nervous or fearful situations. The electrical conductivity of the skin subtly changes in reaction to such emotion. One of the most sensitive measures for emotional arousal is the skin conductance response (SCR) and pupil dilation (PD). This paper demonstrates the logical design behind their mechanism and how it can be used to measure the emotional response and physiological responses of a person by expurgating its response measure. The method adopted uses a novel design method in a custom-based logic scheme that illustrates the logic and its mechanism. Custom intelligent analytics that is mobile inclined is used to visualise and analyse the physiological readings by detecting tonic and phasic changes using the Savitzky-Golay filter. The error in physiological response prediction is computed for each response rate and discussed in the results section.
