Item Making the Case for a Targeted Needs Assessment for mHealth: Prioritizing Regions in sub-Saharan Africa Using Geospatial Mapping(2025-01-07) Zajac, Kimsey; Ludwig, Marie Elvira; Klein, Julia; Kolbe, LutzMobile health has the potential to significantly enhance the effectiveness, accessibility, and personalization of healthcare, particularly in low- and middle-income countries. Nevertheless, for numerous populations, particularly those residing in remote areas, these advantages remain unattainable due to a lack of access to digital health solutions. By employing geospatial mapping of relevant criteria, we aim to identify and prioritize regions in sub-Saharan Africa, where mHealth could demonstrate particular promise. We identified 695 sub-national high-priority regions for mHealth. However, many of these regions lack 2G, 3G, or 4G coverage, necessitating SMS, call-based, and offline mHealth solutions. Our research adds to the literature on the digital divide by highlighting the importance of targeted needs assessments to identify areas in need of digital transformation. It demonstrates the value of geographic information in ICT4D research, particularly for contextualizing findings in mHealth.Item Robin: An Interactive Visualization System and Instructional Tool to Democratize United States Domestic Migration Data(2025-01-07) Bendeck, Alexander; Andris, Clio; Stasko, JohnMigration scholars in the United States (U.S.) study how migration patterns within the country relate to characteristics of migrant origins and destinations, such as political leanings or educational attainment. However, few tools exist for experts to visualize these relationships and easily share insights with students or other interested members of the general public. This data thus remains largely inaccessible to potentially interested non-experts. In this work, we present a system called Robin for visualizing U.S. county-to-county migration data in conjunction with other county-level attributes, designed to be used by experts as a communication aid or by non-experts as an exploratory tool. User studies with migration domain experts and non-experts show promising results in our efforts to support and engage both user groups.Item Introduction to the Minitrack on GeoImpact: Geospatial Technologies for Social Good(2025-01-07) Satpathy, Asish; Erskine, Michael; Diaz Lopez, Andres
