Investigating Safety Awareness in Assembly Operations via Mixed Reality Technology.

OCCUPATIONAL APPLICATIONSWe investigated the impact of using Mixed Reality (MR) technology as a training tool to help trainees identify safety risks during machine assembly tasks, by analyzing their task completion efficiency and safety risk estimation capabilities. As proof-of-concept, an interactive MR module on hydraulic gripper assembly was designed and incorporated in fluid power laboratories to be tested with mechanical engineering technology students. The developed MR environment was evaluated using accident causation models. An environment analysis revealed smooth operation and minimal challenges. Incorporating interactive MR modules into training programs allows practitioners to provide trainees with hands-on experience in a simulated environment while identifying potential safety risks. Addressing limitations, such as simulating physical feedback more accurately, will be crucial for optimizing future safety training effectiveness using MR technology.
