Despite the intuitive appeal of using emerging technologies for disaster preparedness, there is a lack of comprehensive research exploring their applications. This study employs a nationwide 2023 and 2024 survey on technology use for disaster preparedness by older adults and people with disabilities. The survey assessed respondents’ frequency of use, willingness to use, use comfort, perceived usefulness, and attitude toward using technologies. Overall, there were 1696 responses from 2023 and 2024 surveys, with 85 respondents completing the survey in both years. Using the TAM model, PATH findings indicate comfort significantly influenced perceived usefulness but not attitude. Attitude did not significantly influence behavioral intention to use, however, perceived usefulness did influence behavioral intention.
