The effect and reaction of information presentation in surveillance services

Surveillance services are passive work. The surveillance operators are continuously waiting for an alarm. By adding active work to waiting time, the alarm process and disposal time of surveillance operator becomes short. We built a simulated environment of surveillance, and compared physiological reaction of subjects whose experiences were different. As a result, alarm disposal time is shortened in cases where active work was added. The physiological reaction of the subject with a small amount of experience shows little difference both cases. The subject with large amounts of experience shows high tension and little stress in the case of adding active work. We conclude that adding active work to surveillance improves the productivity of surveillance service and to stabilizes the work in the surveillance operator with many amounts of experiences.
