A Development of Visualization Technology through AR-Based Design Checklist Connection

Since the initial design review has the effect of minimizing the design changes needed in the later stages of an architectural project, a process of collaboration between architects, clients, and engineers in this design review is very important. Recently, design review using 3D models rendered in VR or AR, going beyond simple simulation, has been addressed in many studies. However, a synchronization function that provides immediate visualization of design changes is the focus, which has limitations in its ability to review factors required by law related to safety and design. The purpose of this study was, therefore, to develop AR-based design checklist linkage and visualization review technology that facilitates decision making by clients and architects during design review. For this purpose, a method for linking a design checklist in an AR environment using a game engine (Unity 3D) is proposed and various design review visualization functions are developed with consideration paid to the user interface. The efficiency of the design checklist linkage technology and visualization function developed in this study was verified in the pilot project.
