SUMMARY:Evaluating User Perceptions and Usability of CommHEAT: A Community
 -Based Heat Alert Application
DESCRIPTION:Tian Yao, Michael Dorneich, Ruby Thomas, Angelica Brito Diaz, 
 and Chukwuma Maduwuba (Iowa State University); Nicholas Schwab and Mary Lo
 sch (University of Northern Iowa); Caroline Krejci (University of Texas at
  Arlington); Jeremy Caron (City of Des Moines); and Ulrike Passe (Iowa Sta
 te University)\n\nThis research aims to design a community-focused indoor 
 heat emergency alert system for vulnerable populations during extreme heat
  events. The impacts of extreme heat events are becoming more severe, espe
 cially for vulnerable populations. Current warning systems lack informatio
 n about indoor conditions, and many people do not realize the heat risk, a
 ppropriate actions, or available cooling resources. The CommHEAT applicati
 on is designed based on the Fogg Behavior Model to promote people’s heat-p
 rotective behaviors during extreme heat events. It has three key features:
  customized indoor heat risk prediction, community monitoring and support,
  and location-based resources. A multi-mode concept testing (exploratory i
 nteraction, task-based scenarios, and semi-structured interviews) was cond
 ucted with nine heat-vulnerable residents and three stakeholders to evalua
 te the CommHEAT application prototype. The result shows that this smartpho
 ne-based app prototype is promising as an intervention for protecting peop
 le from extreme heat. However, the results also identified challenges like
  trust issues and privacy concerns. Future work will focus on improving th
 e application and assessing its impact on residents’ behavior change durin
 g extreme heat events.\n\nTrack: Product Design, User Experience\n\nMini-C
