With Help from Afar: Cross-Local Communication in an Online COVID-19 Pandemic Community

Crisis informatics research has examined geographically bounded crises, such as natural or man-made disasters, identifying the critical role of local and hyper-local information focused on one geographic area in crisis communication. The COVID-19 pandemic represents an understudied kind of crisis that simultaneously hits locales across the globe, engendering an emergent form of crisis communication, which we term cross-local communication. Cross-local communication is the exchange of crisis information between geographically dispersed locales to facilitate local crisis response. To unpack this notion, we present a qualitative study of an online migrant community of overseas Taiwanese who supported fellow Taiwanese from afar. We detail four distinctive types of cross-local communication: situational updates, risk communication, medical consultation, and coordination. We discuss how the current pandemic situation brings new understandings to crisis informatics and online health community literature, and what role digital technologies could play in supporting cross-local communication

Design and Usability of Interactive User Profiles for Online Health Communities

Online health communities provide a rich source of expertise from experienced patients, but uncovering \u27peer mentors\u27 with shared circumstances is like finding a needle in a haystack—a problem that will escalate as these communities grow and diversify. We investigated interactive health interest profiles (HIPs) that summarize health-related terms extracted from users\u27 community posts. Through iterative design, we explored practical designs that accommodate differences in users\u27 community participation in three HIP prototypes: Text, Word Cloud, and Timeline. By comparing prototype usability with patients and design experts, we found that patients accurately used each prototype but completed some tasks faster with the Timeline HIP. Despite this advantage, patients preferred the Text HIP. Design experts and patients agreed that simple data overviews and granular details with salient cues that invite interactivity are key design considerations for HIPs. Findings offer key design considerations for HIPs that patients find most useful when forging critical connections
