Abstract
A method of analyzing dual biosignals (finger plentysmogram (FP) and respiration) to determine mental stress is proposed. Experiments using visual search tasks confirm that the 0.1 Hz frequency component of the second component signal generated by principal component analysis (PCA) provides a strong correlation to stress levels
