ABSTRACT
This chapter presents three perspectives that show what kind of difference bodies, spaces, and other physical aspects make in interaction and how that difference can be analyzed in terms of power and authority. The first perspective, presented by Vincent Denault and Pierrich Plusquellec, consists in considering the human body not only as a subject but also as the object of analysis and reflects on ways in which experimental research on nonverbal communication may complete observation of naturally occurring interaction. The second, presented by Nicolas Bencherki and Alaric Bourgoin, proposes a decentering of analysis towards objects and suggest that it is possible to describe them as communicating without reducing them to tools that are only relevant when they are used by human individuals. Finally, a last perspective, presented by François Cooren and Huey-Rong Chen, bridges the gap between verbal and non-verbal communication and proposes a ventriloquial analysis that embraces the confusion between human and non-human participants rather than seeking to neatly sort them out.
