Migration studies is an interdisciplinary field, requiring collaboration between researchers with varying levels of geospatial and quantitative data literacy. Geospatial tangible user interfaces (GTUIs) offer promising opportunities for embodied and collaborative spatial exploration of migration data. Few GTUIs, however, provide real-time visual feedback of data values to help users collaboratively identify trends. To address this gap, we present GeoTEAM, a novel tangible system for real-time, dynamic regional exploration, co-designed with migration and HCI researchers. GeoTEAM features active tangible dials with built-in touchscreens designed to control time and navigate map layers for net migration and various environmental sub-drivers in a multi-surface environment with tabletop and wall displays. We evaluated this system with nine pairs of researchers possessing multi-expertise in geospatial data literacy. Qualitative findings show that our system promotes collaboration, intuitive sense-making, and increased user confidence, enabled by physical interaction and real-time feedback from the active tangibles.
