The purpose of this chapter is to explore evolving understandings of urban life and infrastructure in smart cities in relation to experiences, interactions, and augmentations. As such, a review of the research literature is conducted focusing on infrastructures, experiences, interactions, and augmentations in smart, learning, and future cities. Issues, controversies, and problems emerging from the literature review are highlighted, contributing to formulation of a conceptual framework for urban life and the ambient featuring evolving infrastructures in smart cities. Using an exploratory case study approach combined with an explanatory correlational design, the conceptual framework is operationalized for use in this chapter. Through the lens of emerging infrastructures for experience, interactions, and augmentations, variables are identified, explored, and correlated to inform understandings of smart cities while identifying directions for future research and practice.
