ABSTRACT
Everyone interacts with the world differently — guided by their own attitudes, their communities and families, and their smartphones with apps. Ever since smartphones became a virtual assistant for us to interact with the world on the move, mobile apps have never been proficient at helping people gather together virtually and informed of nearby and online updates and events. Researchers are excited about new technologies that could revolutionize how people sense and interact with everyday objects and locations. As one of the two most important contexts, location is becoming a key entry for mobile Internet. Ubiquitous smartphone and location information are enabling these new mobile smartlife scenarios near a certain object or location towards mobile smart life. As one of the two key components of a mobile context, localization has been the subject of extensive works ranging from algorithms, models, supporting technologies, to systems and applications. The chapter also presents an overview of the key concepts discussed in this book.
