Over the years, Hugh Dubberly has managed to capture and explain complex ideas and processes using his concept mapping technique. In this concept map titled "Model of Play", Hugh visually describes the process of play.
The extract below is taken from the DDO website:
This model is built on the idea that play is a type of conversation. It involves two individuals, who might also be teams, or points of view with in a single person, or a virtual person and a real person. Through conversation, they create a shared world in their imaginations, which leads to fun."
