Optimizing interaction design in XR for safety improvements on construction sites

This research investigates how to optimize interaction design in Extended Reality (XR) to improve safety on construction sites. The study focuses on developing an XR training program that enhances workers’ ability to recognize and respond to hazards, particularly those involving construction vehicles. Using a user-centered design approach, the study involved construction workers and safety experts in the iterative development and evaluation of an XR training prototype. The prototype was developed using Unreal Engine 5.2.1 and tested on the HTC Vive Focus 3 headset. The evaluation involved user testing sessions, questionnaires, and semi-structured interviews to gather feedback on user experience, technology acceptance, and areas for improvement. The final prototype incorporates a range of features and functionalities that enhance the learning experience and promote the acquisition of essential safety skills. These features include realistic 3D models of construction vehicles and environments, intuitive
interaction mechanics, dynamic feedback mechanisms, and personalized learning paths. The findings of this study contribute to the field of Human-Computer Interaction by demonstrating the feasibility and effectiveness of VR-based training for construction site safety and providing insights into the optimization of interaction design for immersive learning experiences.
