The galvanic skin response (GSR), also known as electrodermal response, measures changes in electrical resistance across two regions of the skin. Galvanic skin response can measure arousal levels in children with autism; however, the GSR signal may be overwhelmed by the vigorous movements of the children. This paper introduces ActionGSR, a wireless sensor capable of measuring both GSR and acceleration simultaneously in an attempt to disambiguate valid GSR signals from motion artifacts.
