A study about feature extraction for stress detection

Stress can be associated with depression, heart disease, gastrointestinal problems, asthma, obesity, Alzheimer´s disease, impaired driving, low productivity at the workplace, therefore stress detection is a very important research subject. Stress detection using the user´s electrodermal activity is a very poor documented research area. This study will focus on presenting a few filtering techniques used to estimate the skin conductance level for stress evaluation, as well as a method used for establishing the user´s latency between a given stimuli and the reaction to that stimuli.
