Local Knowledge in Visually Mediated Practice

Visualization tools such as maps, models, and computer images are used increasingly as means of involving people more effectively. We examine how a visualization tool in the form of a map-based model may shape the knowledge local people bring to the planning table. The analysis was guided by the concept of mediated action as it has been developed in sociocultural theory. We found that local knowledge was conditioned by a complexity of factors, including the dynamic of actions that develop around the tool and the way of looking imposed by map-based representation. The suggestion being made is that visualization tools, although bringing people closer to the planning process, also disconnect them from their local knowledge base.
