Different partners are likely to be part of different activity systems, with different objectives, different motivations and different tools.

Shared situational objects can be a turning point in negotiations between such partners – reflecting their different perspectives on the same themes. These shared objects sit between the activity systems and offer the potential to bring them together.

Space can act as one of these shared objects, if partners share the same space and have to negotiate its division.
