Highly sensitive estimation of significant SCR for wrist-worn electrodermal activity

Abstract

We proposed a method to utilize EDA from wrist to counter its lack of sensitivity in estimating significant SCR. Comparing the estimated time of SCR at the transition from baseline to task, a delay between EDA from wrist and finger were confirmed with correlation to slope of SCL. Adaptive thresholding that controls threshold of discriminating SCR by the value of past slope of SCL showed ability to estimate transition with high sensitivity.
