摘要：AbstractThe public has access to a range of mobile applications (apps) for disasters. However, there has been limited academic research conducted on disaster apps and how the public perceives their usability. This study explores end-users’ perceptions of the usability of disaster apps. It proposes a conceptual framework based on insights gathered from thematically analyzing online reviews. The study identifies new usability concerns particular to disaster apps’ use: (1) content relevance depends on the app’s purpose and the proximate significance of the information to the hazard event’s time and location; (2) app dependability affects users’ perceptions of usability due to the life-safety association of disaster apps; (3) users perceive advertisements to contribute to their cognitive load; (4) users expect apps to work efficiently without unnecessary consumption of critical phone resources; (5) appropriate audio interface can improve usability, as sounds can boost an app’s alerting aspect; and, finally (6) in-app browsing may potentially enhance users’ impression of the structure of a disaster app. As a result, this study argues for focussed research and development on public-facing disaster apps. Future research should consider the conceptual framework and concerns presented in this study when building design guidelines and theories for disaster apps.
