The anthropologist Edward T. Hall developed the theory of proxemics, which explores how people use and perceive space in various social and cultural contexts. He coined this word in the early 1960s.
Proxemics is the amount of space people prefer to have when engaging in conversation with others.
There are typically four zones / spaces that you will work within.
The public zone / space
The social zone / space
The personal zone / space
