Abstract
Emotion recognition is an ever-expanding field with applications ranging from medical to psychological to commercial. Currently, innovative methods are being used in emotion detection research, with a focus on stress, a condition that is an integral part of everyday life and can have short and long term consequences. Electrodermal activity (EDA), also known as galvanic skin response (GSR) or skin conductance (SC), is a quantitative method of measuring variations in sweating by detecting changes in electrical conductivity. Two 3D virtual reality environments were developed with the specific aim of eliciting emotions. Each environment comprises seven tasks which incorporating a stress-inducing stimulus, termed "stressor", derived from prior literature research.
The primary objective of the first environment is to induce stress, whereas the second environment has been designed to provide a less stressful experience by alleviating stressors
