Abstract

In this study, NASA-TLX (National Aeronautics and Space Administration-Task Load Index) scale was used to evaluate subjects’ fatigue before and after digital cognitive tasks, and the performance of operators’ assembly operation was adopted as the criterion so as to study the validity and applicability of NASA-TLX scale. The results suggested that NASA-TLX scale showed a good reliability and validity when it was used to evaluate subjects’ mental fatigue induced by digital cognitive tasks. There was a significant correlation between NASA-TLX scale and the performance of assembly tasks, which indicated that NASA-TLX scale had a good predictive effect on operators’ performance to a certain extent. NASA-TLX can serve as an ideal tool for mental fatigue measurement in assembly work.
