Productivity Improvement and Stress Reduction by Showing Information to a Surveillance Worker

Abstract

System surveillance is a function required for continuous operation of a system which consists of various apparatus and networks. Many service providers try to raise their productivity. Their methods show some information to a surveillance worker after the alarm occurs. As another method of the rationalization, a surveillance system shows some information to the worker on the waiting time. The simulated environment of surveillance has been built. There are three kinds of screens that are shown to the subject on waiting state. Passive case test uses passive waiting screen that displays no information. Directed case test uses directed waiting screen that displays operation method. Active case test uses active waiting screen that displays list of surveillance objects and can be scrolled by subject. Subjects’ stress are performed by R-R interval. By comparing 12 subjects, it was confirmed that they are working efficiently in the test which display some information, and active case test that encourages voluntary browsing allows subjects to relax. It is an effective method of a productivity improvement and stress reduction to display the information that encourage voluntary browsing on waiting time.
