Abstract
Traditional tools for ergonomic assessments of workstation designs often involve ergonomists using Digital Human Modeling (DHM) software to simulate worker motions. However, these tools can be limited by posture prediction algorithms that fail to capture the full range and variability of human behavior. Virtual Reality (VR) offers an alternative by enabling workers to perform tasks within simulated workspaces, where their movements are captured using motion tracking systems. This approach generates kinematic data that can overcome the shortcomings of DHM tools, facilitating improved accuracy in the ergonomic evaluation of workstation design. Building multiple alternative virtual workstations is not only quicker but also more cost-effective than building physical prototypes. In this paper, we introduce a VR application, ErgoReality, and discuss its three main components: simulation development, data collection, and ergonomic analysis. We also explore further research areas to enhance the tool, address potential limitations, and propose strategies to mitigate these challenges.
