摘要

The present study investigates the comparability of ergonomically relevant movement data between virtual (VU) and real (RU) environments, using knee-straining activities as a case study. The flexion angles of the knee joints of 24 test subjects were recorded in both environments using a motion capture system and analyzed using the CUELA method. The findings indicate a substantial degree of intraindividual congruence in the flexion angles between VU and RU, accompanied by a concomitant decrease in movement variability within the VU. These disparities may be attributable to the absence of physical loads and sensory feedback. The findings underscore the notion of the transferability of movement data collected in virtual environments and highlight the potential of VR-based methods for the ergonomic evaluation of workplaces in early planning stages.

Practical Relevance: Virtual environments have the potential to facilitate ergonomic evaluation in the early stages of development, prior to the physical presence of workstations. The findings of the study indicate that the movement data from virtual reality is sufficiently precise and consistent to replicate real designs. Consequently, risk assessments can be conducted digitally and reproducibly in the future. This change will result in new opportunities to improve preventive occupational safety and to optimize workplaces and training methods. The integration of technological enhancements, including haptic feedback and hybrid simulations, has the potential to substantially expand the applicability of these systems.
