(2014) show, during sleep measurements, that measurement of EDA on the wrist typically gives greater responsivity than measurement on the traditional palmar surface. In this work, we present a pilot study in Virtual Reality (VR) that uses a multi-sensory approach of Electroencephalography (EEG), galvanic skin response (GSR), and Heart Human trust is a psycho-physiological state that is difficult to measure, yet is becoming increasingly important for the design of human-computer interactions. ДЄutoEmotive: Bringing Empathy to the Driving Experience to Manage Stress (Hernandez, Javier, et al., 2014). Pieper and Laugero used features extracted from Q Sensor data for their publication on emotional eating in the journal Appetite (Pieper et al., 2013). (2015b) described how a theory of multiple arousals explains asymmetric EDA findings. Here is an example showing reasonable EDA data collected on the ankle, with comparison to the wrist (Fedor et al., 2014). (2010) describe the relationship between traditional palmar wrist placement of EDA recording devices with dry electrodes measured during three conditions: physical activity, emotional stimuli, and high cognitive load.ДЄmbulatory EDA sensors using dry electrodes and placements on the wrist or ankle have been validated not only in the epilepsy/medical journals listed above, but also in a growing number of other areas. The work shows that despite the amplitude being lower on the vertical wrist, the EDA signal is still discernible and shows clear skin conductance responses with stimuli. (2012) demonstrate correlations between EDA responses across a number of dermatomes. By measuring BPM of a person using Heart Rate sensor the prototype can classified the persons emotional level, and with Galvanic Skin Response sensor, the product can measure the amount of conductivity of current pass through the skin in micro Mho unit. Estimates of parasympathetic nervous system activation or vagal tone can be made by extracting the high frequency component of this heart rate variability. Stress Indicator is a prototype that measure humans stress levels by using two parameters, heart rate and sweat activity. We can observe increases in sympathetic activation by monitoring subtle electrical changes across the surface of the skin.Д¬hanges in heart rate (the time between the peak of each heart beat) occur as a result from both sympathetic and parasympathetic activation. How do we measure sympathetic activation? The skin is the only organ that is purely innervated by the sympathetic nervous system (and not affected by parasympathetic activation). It can be stimulated by the consumption of a hearty meal or deep breathing. Parasympathetic activation occurs when your body needs to slow down and relax. In some medical conditions (e.g., epilepsy), it shows significant increases that are related to specific brain structures activation. It increases also with stressors - whether physical, emotional, or cognitive.

The results are also printed to the terminal for debugging / fine tuning.Sympathetic activation (also Sympathetic arousal) increases when you experience excitement, or something important is happening or about to happen. when it detects a change in GSR > 5% the buzzer will go off. The program will take a baseline and then start running. In this paper we propose analysis and analog circuit design for GSR (galvanic skin response), microcontroller firmware used for data acquisition which communicates data to the computer via UART line for the further processing as well as the potential GSR use case.

Make sure to change to ping mapping in the code to match the pin mapping you select. Load code onto mbed, plug GSR into an Analog port and buzzer (optional) into a digital port.

Sensitivity adjustable via a potentiometer.Grove вЂ“ GSR allows you to spot such strong emotions by simple attaching two electrodes to two fingers on one hand, an interesting gear to create emotion related projects, like sleep quality monitor. Strong emotion can cause stimulus to your sympathetic nervous system, resulting more sweat being secreted by the sweat glands. GSR, standing for galvanic skin response, is a method of measuring the electrical conductance of the skin.
