The Open Dynamic Interaction Network (ODIN) is a cost-effective mobile platform designed for advanced social and behavioral research. ODIN represents a new paradigm in scientific exploration, moving beyond traditional methods of simple surveying and social network analysis. It enables the continuous and contextualized collection and analysis of individual and interpersonal data. By utilizing ODIN, researchers can extend their studies beyond static snapshots of individual and social life. The platform allows for the gathering of high-dimensional data streams from study participants over extended timescales, offering new insights and a deeper understanding of social and behavioral dynamics. This innovative approach facilitates a more comprehensive examination of social interactions and behaviors, leading to richer and more accurate scientific discoveries.
