To construct a virtual reality (VR) experience system for interior damage due to an earthquake, VR image contents were created by obtaining images, sounds, and vibration data from multiple devices, with synchronization information, in a room at the 10th floor of 10-story RC structure tested at E-Defense shake table. An application for displaying 360-degree images of interior damage using a head mount display (HMD) was developed. The developed system was exhibited in public disaster prevention events, and then a questionnaire survey was conducted to assess usefulness of VR experience in disaster prevention education.
