With the spread of mobile augmented reality, it has become very difficult to consider digital space and physical space independently. In this book, the authors identify and discuss the state 'Second Offline' which refers to a real-world environment whose elements are augmented by virtual information and one in which individuals are constantly referring to the online world. 'Second Offline' is observed across a wide range of social contexts and the relationship between superimposed digital online information and physical offline information is increasingly important. This book analyses the cooperative relationship between online and offline and also examines situations where there may be a conflict between these realities. Furthermore, the authors discuss the possibility that in addition to influencing the physical space, the digital world actually causes some of the physical world to be lost. Offering a discussion of the implications of a post-mobile society in which second offline is widespread, this edited collection will be of interest to students, scholars and practitioners working in sociology, mobile media and cultural studies more generally.

This book presents current research on mobile Internet society. Past research was not able to show a clear analytical framework, thus was unable to close in on the fundamental changes in that society. This book, however, analyzes mobile Internet society by introducing the concept of "doubling of time and place" and the analytical framework of the "second offline." The emergence of the smartphone has made Internet use easier, and now, people are constantly using online information in the midst of their daily lives. Our society is transitioning from the first offline society, a society without being connected to Internet, to the second offline society, where users are connected to the Internet at all times. In this second offline society, our sense of time and place are beginning to change. Broadcast and communication media have made possible the overlapping of different places, which has been called the doubling of place. Furthermore, virtual reality (VR) and augmented reality (AR) technologies have enabled the overlap of different times, which this book calls the doubling of time. The smartphone makes both possible. With the second offline and the doubling of time and place as keywords, the book takes into consideration research that includes, among other topics, the media usage of young adults, selfies, education, social media usage, mobile games, work stations, and consumer activity in the mobile Internet society.
