University of Central Florida EECSDefinition: Urban ComputingUrban computing is an emerging field of study that focuses on the use of technology in public environments such as cities, parks, forests and suburbs. It also studies the interaction between humans and such environments, which is becoming increasingly common as access to computing devices extends beyond home and office02/17/2009 Participatory Urbanism 2Definition: Participatory UrbanismParticipatory Urbanism is the open authoring, sharing, and remixing of new or existing urban technologies marked by, requiring, or involving participation, especially affording the opportunity for individual citizen participation, sharing, and voice.02/17/2009 Participatory Urbanism 3The Concept02/17/2009 Participatory Urbanism 4Areas (not) to focus
