Enhancing hurricane risk perception and mitigation behavior through customized virtual reality

Hurricanes are one of the most destructive natural disasters, and proper preparation and mitigation are essential to enhance resilience. However, homeowners may have inaccurate risk perceptions, resulting in inadequate mitigation decision-making. Virtual reality (VR) damage visualization has the potential to communicate hurri-cane risk effectively and improve disaster resilience. Previous studies utilizing VR for hurricanes have primarily focused on disaster response such as evacuation, and often presented generalized visualization consistent across all users. This study presents a methodology for offering individual users a customized tool to experience the impacts of hypothetical hurricane events on their residential structures and explore the effects of various building retrofit actions in customized 3D virtual environments. The methodology was tested with 25 participants. Par-ticipants experienced structural damage and utility disruptions caused by hurricanes in their own residential homes in a customized, immersive virtual environment. Participants' pre-and post-VR risk perceptions, as well as their choices of mitigation actions were surveyed. The results indicate that customized VR was effective in enhancing risk awareness and that participants were able to reduce their structural damages in hypothetical hurricane events by adopting various mitigation measures after the customized VR experience. The outcomes suggest that customized visualization of potential damages in virtual environments can effectively help disaster preparation and mitigation.
