When disasters such as fires or earthquakes occur, rescue personnel entering buildings are prone to spatial disorientation when the buildings have complex indoor compartments or compartments with high uniformity and similarity. This situation may expose both the people waiting for help and the rescue personnel to dangerous conditions. Therefore, this research study proposes that government search and rescue units can pre-establish a database of indoor spatial information for buildings. When a disaster occurs, the spatial information needed by rescue personnel can be transmitted in real-time and displayed on wearable 3D display systems. Given this proposal, we have developed a “Building Information Guiding System” (BIGS) to provide spatial information in real-time through the “Wearable Augmented-reality Seeking System” (WASS). BIGS uses QR codes presented at different information anchors in a building to display various embedded spatial information on horizontal and vertical escape paths, the locations of exits, firefighting equipment, and electrical power generator sets. According to the information provided by BIGS, 3D virtual arrows can be displayed in the air by the HoloLens augmented reality helmet worn by the rescue personnel in order to guide the direction toward the target. The BIGS system can read the Building Information Modeling (BIM) file submitted with new construction projects to the government construction management units and then input necessary spatial information to the file to establish an exclusive 3D spatial database for that new construction. BIGS can also construct an entire 3D spatial database for an old building by reading the BIM 3D point cloud model created through 3D laser scanning. This study explores the feasibility of using the BIM model to construct the BIGS system, the presentation mechanism of serial QR codes in real space, and the steps and modes of inputting spatial information into the 3D spatial database.
