Recent advances in technology have made all kind of sensors more easily attainable and better software has made them easier to use. Within the domain of Human Machine Interactions and the area of Cognitive research, this is reflected in the use of all types of physiological measurements. These measurements include heart-rate and skin conductance.
Physiological measurements are a very powerful tool for social scientists. They allow for both the replacement and supplementation of the more traditional questionnaires by more objective measurements of excitement, stress and emotional state. Within the BMS lab, the shimmer skin conductance sensors and E4 Empatica watches are often used for this purpose. The latter is also usable for more active settings when participants need to be able to move freely, as it is worn like a watch.
