Actors
The narrative ecology is occupied by 4 actors which exert an influence on each other. Be aware that in receiving, contributing and/or determining the outcome, actors exert their social and cultural contexts; attitudes, expectations, disposition, roles and values.

Participants
A participant is defined here as an actor receiving, contributing and/or determining the solution. Participant is used here in place of the more traditional term user, to emphasize the active nature of interaction. Participants can be divided into three groups of interaction and influence. Audience participants can play a part in any combination of the receiving, contributing and determining roles, client participants tend to influence the outcomes of some or all the receiving, contributing and determining roles and secondary participants are not present during the project outcome and only know of the project through its influence.

Spaces
A space can be defined as an actor embodied in the virtual or physical built environment, and therefore exerting a presence that can be defined in terms of a spatial analysis of light, volume, obstacles and flow routines, amongst others.

Things
Things are designed objects, products or services, with specific roles. As actors, these exert a design-centered view of the world of activities and meaningful relationships which participants have with it.

Interactions
Although the flow of interaction cannot strictly be seen as a tangible actor, it functions as an essential, without which an ecosystem would not be possible. This actor can have behaviours which range anything from a simple linear pathway, to a complex network of interdependence and interaction.
