Workspace awareness
Definition:

The affordances of physical workspaces allow people to maintain awareness of others' locations, activities, and intentions relative to the task and to the space-awareness that enables them to work together more effectively. We call this workspace awareness: the collection of up-to-the minute knowledge a person uses to capture another's interaction with the workspace.
