Abstract
A stressor detection system () comprises sensor means () arranged for being attached to a person for obtaining a time-varying signal representing a physical quantity relating to an environment of the person, and processing means () for deriving a stressor value from the obtained signal representing a degree to which the environment is inducing stress in the person. The processing means is arranged for deriving an amount of complexity comprised in the signal, and for deriving a higher stressor value for a larger amount of information. The processing means is further arranged for performing a spectral frequency analysis of the signal and for deriving the stressor value also in dependence on the spectral frequency analysis. The sensor means comprises a microphone (), a camera (), and a tri-axial accelerometer.
