An Analysis of a Stress Checking System

- The Evaluation of VDT Work Fatigue by Electrocardiogram RRI Analysis -

Abstract

We developed a system that can objectively evaluate fatigue of long Visual Display Terminals, using both electrocardiogram data and self-reporting questionnaires. The objective was to identify the elements that contribute to stress within the organization. R-to-R interval (RRI) analysis of the electrocardiogram data allows the establishment of objective stress indices, and the rationalization of diagnosis. We therefore propose the introduction of biometric measurement to stress checking systems.
