摘      要：The public has access to a range of mobile applications(apps)for ***,there has been limited academic research conducted on disaster apps and how the public perceives their *** study explores end-users perceptions of the usability of disaster *** proposes a conceptual framework based on insights gathered from thematically analyzing online *** 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 lifesafety 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 *** a result,this study argues for focussed research and development on public-facing disaster *** research should consider the conceptual framework and concerns presented in this study when building design guidelines and theories for disaster apps.
