Abstract

In order to improve safety of lifting operation, optimal visual field cone and maximum visual field cone were analyzed considering visual angle and visual distance, and driving level of visual information on lifting operation was measured from the angle of geometric optics. Then, with lifting drivers as subjects, a virtual test scene was constructed according to operation tasks, visual cognition parameters were collected by using eye movement tracking technology, and eye movement measurement experiment of visual information driving level was designed. Finally, Work Breakdown Structure (WBS) and kinetic element analysis method were used to develop act therbligs coding system, and driving effects of visual information on lifting operation rate and error were studied. The results show that the higher driving level is, the faster lifting operation will be, and there is a strong exponential relationship between them. The driving level with correct operation behavior is generally higher than that with wrong behavior, namely, it is not easy to have wrong operation when driving level of visual information is high. © 2022 China Safety Science Journal.
