This study conducted hazard perception training on inexperienced personnel intended for future use using 360-degree images for novice workers at housing construction sites. We compared training effectiveness and subjective workloads regarding four combinations of media types and display devices as experimental conditions (360-degree still image/HMD, 360-degree video/HMD, 360-degree still image/PC monitor, and 2D still image/PC monitor). The memory task for hazard information showed high performance in all experimental conditions. However, for the memory task of hazard location, the 2D still image/PC monitor condition showed low performance and poor mental workloads. Realistic presence varied across experimental conditions, and there was no significant relationship between the presence and the subjective risk. In terms of motion sickness, all experimental conditions had low ratings. Based on these results, we proposed effective conditions of media types and display devices regarding hazard perception training using 360-degree images depending on the training situation.
