How do people interact when they are on the move? How do people interact in order to be mobile? How do people coordinate the mobility of others? How does mobility feature in social interaction? ‘Multimodal interaction’ and ‘mobility’ are of increasing interest to scholars across disciplines. Interaction and mobility is the first book to study these aspects comprehensively. It provides cutting-edge research by international scholars who use video-recordings of real-life everyday interactions for studying in close detail human social interaction in such diverse multimodal settings as airplanes, cars, traffic control centres, dance schools, museums and other public places, and as part of such activities as instructing, navigating, identifying an enemy on the battlefield, organising a meeting, playing videogames, shopping, performing and dancing. Together, these studies highlight features of social interaction, including language, embodied conduct, and spatial and material orientation, for being mobile, for interacting on the move, so that mobility becomes a ubiquitous feature of our lives. This book is a valuable resource to anyone interested in multimodal interaction and mobility.
