A system for remote monitoring of mental effort

Real-time monitoring of mental effort enables the possibility of dynamically adapting the challenge of a task given to an individual, thereby maintaining the skill-challenge balance. In this paper we propose a remote monitoring system for assessing mental effort or cognitive load using low cost Galvanic Skin Response (GSR) sensor. The variations in the skin conductance level measured using the GSR signal, is used to generate a score in real-time, which reflects the level of mental load experienced by an individual. This score gives an additional information about the efforts given by the participants and hence is an important value addition for assessing one's mental workload while doing any task. The score is initially transmitted to a mobile gateway device for local monitoring and later transmitted to a backend server for offline analysis and tracking of the performance over a period of time.
