Thus the more primitive emotions would be expected to be elicited by more primitive aspect of the environment, and only at higher levels of evolution would complex classification of stimuli have had related emotions associated with them (Ross & Jain, 2003). This evolution of emotions may in fact be reflected in the brain systems that generate them, with emotions linked to survival arising from evolutionarily old brain systems.
#Galvanic skin response sensor voltage skin
Skin conductance, galvanic skin response and electro-dermal response. Rather, emotions evolved from very simple mechanisms that ensured harm avoidance and attainment of vital physical resources into more complex mechanisms that guide complex social behavior. A tiny electrical voltage so small it is not felt is applied through two electrodes. This vast range of emotions and the related goals is not likely to have been formed concurrently. In a similar fashion numerous emotional tags can be given to stimuli that promote or hinder the attainment of goals ranging from basic individual survival goals to more complex social interaction goals (Table 1). Another example is the emotional tag of happiness that can be assigned to any stimulus that advances the goal of well-being. The results obtained are realistic and provide a measure of accuracy.įor instance the emotional tag of fear can be attached to a threatening stimulus in so far as the latter can potentially impede the goal of survival. LabVIEW is a graphical programming language that includes all tools necessary for data acquisition, data analysis, and presentation of results. These measurements are transmitted to a LabVIEW add-on card for further data processing and analysis. A system is constructed that measures physiological parameters along with signal conditioning units.
This system, in conjunction with a certified examiner, is used to analyze a subject’s stress. The heart rate is predominant in deciding the emotion of a person. Two physiological parameters are considered: galvanic skin response (GSR) and finger tip temperature (FTT).
The present work monitors the physiological parameters by connecting sensors at specific points on a test body. These measurements are then compared with the normal levels of the subject. A generalized system measures changes occurring in the body of a subject, such as heart rate, blood pressure, respiratory rate, electro-dermal (Galvanic skin resistance) activity, and arm and leg motions. In this work, a person’s physiological parameters are measured to decide emotional status. AbstractEmotion is the excited mental state of a person caused by internal and external factors.
