The purpose of this research is to develop a human monitoring system for preventative safety in sea transportation. An autonomous facial-expression monitoring system, named 'KII (Kinetic Information Integrator) system' was developed. This system consists of multiple network cameras and Microsoft's KINECT sensor. Network cameras will be controlled autonomously so as to follow subject's face from different directions even though he or she is walking around.The heart is controlled by the autonomic nervous system, and the sympathetic nervous system and parasympathetic nervous system are well known to represent the mentally stressed or relaxed states, respectively. ECG was measured by using a mini physiological measuring system. Heart rate variability was analysed, and subject's physiological and psychological changes were also evaluated. The effectiveness and validity of these systems have been demonstrated in the field experiments.
