Abstract

Biometric input devices can provide assistive technology access to people who have little or no motor control. We explore a biometric control interface based on the Galvanic Skin Response, to determine its effectiveness as a non-muscular channel of input. This paper presents data from several online studies of a locked-in subject using a Galvanic Skin Response system for communication and control. We present issues with GSR control, and approaches that may improve accuracy and information transfer rate.
