The sweaty hands can be consigered as a warning in this case.Galvanic skin response provides with data of the human state, which are independent on the subjective feelings of the patient.The software of galvanic skin response analysis has been developed by using NI LabVIEW.Further research inludes the development of algorithms for the analysis of emotional states by improving this system with additional types of monitoring, such as registration of the pulse wave, respiration monitoring etc.В статье описан алгоритм разработки программно-аппаратного комплекса определения уровня эмоционального напряжения человека на основе данных кожно-гальванической реакции. It is based in the primitive 'fight or flight' response, whereby the body prepares itself for the exertion needed to deal with a perceived threat by increasing sweat activity to cool itself. This pattern is used to diagnose various dysfunctions such as an epileptic seizure. Skin Conductance is also known as Galvanic Skin Response (GSR) or Electrodermal activity (EDA), but Skin Conductance is the currently used term.
LabVIEW is a graphical programming language that includes all tools. Usually, it is attached to fingers of hands or feet.The conductivity of the skin depends on the amount of perspiration segregated in the area under the attached electrodes. Two physiological parameters are considered: galvanic skin response (GSR) and finger. To investigate the emotional state in response to stimuli of different types, the system for registration and analysis of galvanic skin response has been developed.The galvanic skin detector can be attached to any part of the body. tip temperature output and channelAI1 to Galvanic Skin Response meter output. Galvanic skin response definition is - a change in the electrical resistance of the skin that is a physiochemical response to emotional arousal which increases sympathetic nervous system activity. Blood oxygenation level is associated with cardiovascular fitness, and raising oxygenated blood coloration in human faces increases perceived health 30 34. LabVIEW data acquisition add on card as shown in Figures 3, 4, and 5. Figures 20 and 21 show the obtained values of oxygen saturation for the two patients, respectively. These experiments demonstrate the malleability of body image and the brain's remarkable capacity for detecting statistical correlations in the sensory input.The paper describes an algorithm of development of the hardware and software that determines the level of emotional stress of a person on the basis of galvanic skin response. Obtaining the value of the galvanic skin response in the MCT. The fact that the illusion could be significantly diminished when the real hand was simultaneously visible suggests that the illusion and associated SCRs were due to perceptual assimilation of the table (or rubber hand) into one's body image rather than associative conditioning. Depending upon the theme, emotion will be evoked in the subject.
In the current work, a subject whose Galvanic skin response (GSR) is to be measured, has been shown/played a movie clipping, images or recorded audio signals. This variation in skin resistance ranges from 5k to 25k. The illusion was much less vivid, as indicated by subjective reports and SCR, if the real hand was simultaneously visible during stroking, or if the real hand was hidden but touched asynchronously. ActiveTwo compatible 3-D accelerometer, skin temperature, blood volume pulse, respiration, and skin conductance sensors. Drier the skin is, higher will be the skin resistance. Sensations could even be projected to anatomically impossible locations. If the table or rubber hand was then 'injured', subjects displayed a strong skin conductance response (SCR) even though nothing was done to the real hand. Subjects perceived touch sensations as arising from a table (or a rubber hand) when both the table (or the rubber hand) and their own real hand were repeatedly tapped and stroked in synchrony with the real hand hidden from view.
