Abstract

Over the last decade, researchers have used virtual- and mixed-reality (VR-MR) techniques for various safety-related applications such as training, hazard monitoring, and preconstruction planning. This paper reviews the recent trends in virtual- and mixed-reality applications in construction safety, explicitly focusing on virtual-reality and mixed-reality techniques as the two major types of computer-generated simulated experiences. Following a systematic literature assessment methodology, this study summarizes the results of articles that have been published over the last decade and illustrates the research trends of virtual- and mixed-reality applications in construction safety while focusing on the technological components of individual studies.

Highlights

  • Injuries in construction occur at higher rates compared to many other job sectors, resulting in the loss of lives and profits [1]

  • Due to the apparent ineffectiveness of current safety practices, academic studies have explored the use of innovative intervention methods offered through Virtual Reality (VR) and Mixed Reality (MR) techniques [3,4]

  • This study focuses on the technological components of those virtual- and mixed-reality (VR-MR) studies and discusses individual examples of research projects that implemented such technologies for construction safety application

Summary

Introduction

Injuries in construction occur at higher rates compared to many other job sectors, resulting in the loss of lives and profits [1]. Due to the apparent ineffectiveness of current safety practices, academic studies have explored the use of innovative intervention methods offered through Virtual Reality (VR) and Mixed Reality (MR) techniques [3,4]. By intentionally limiting the scope of the review to VR and MR, this study can highlight interactive safety interventions with detailed summaries of application areas, while separating VR and MR from the larger, general field of BIM (Building Information Modeling), 4D CAD (Computer-Aided Design), and other visualization technologies. The expected outcome of this content-analysis-based review can benefit both industry professional and researchers who find it necessary to design and develop an efficient application employing VR/MR technologies to enhance safety processes in the construction domain
