Abstract
<p>We aimed at developing a simple fatigue measurement system, so far the influence of the noise under laboratory environment is small, and the experimenter side who uses a simulator. We have been studying fatigue measurement in a manageable environment. In order to show the effectiveness of our proposed method in a real environment, we collected fatigue measurement indexes before and after work for technical engineers of Software Development Company operating VDT work, Changes before and after were compared and examined. As a result, in the conventional indexes, a significant difference was found in the pulse rate and the flicker value, we found that there are significant differences between before and after some speech of fundamental frequency, speech power, period of speech indexes. In VDT work, there was a difference in flicker value as a fatigue measurement index, which was also supported by subjective symptoms and self-evaluation results. In addition, since significant differences were found also in the speech index, in the work centering on the VDT work as well as the bicycle simulator so far, it was shown that speech indexes can be effective indicators.</p>
