Exploring Sensor Usage Across Four Urban Communities of Stakeholders

We define our stakeholders as any people who occupy or pass through public urban spaces, including policemen, cab drivers, pedestrians, construction workers, businessmen, etc. To gain insight into how stakeholders spanning diverse age groups, interests, urban spaces, social and economic backgrounds approach sensing and public authorship, we scoped our study around four communities, making the following assumptions about each:

• Students are a young demographic occupying spaces in and around universities, with interests that reflect similar educational backgrounds and lifestyles
• Parents form an older group, characterized by personal and family interests in spaces that revolve around children (schools, playgrounds, etc) as well as work (office, etc.) and friends (theatres, malls, etc)
• Bicyclists traverse a wide range of urban spaces with vested interests in roads, parks and traffic, among others
• The homeless are a low-income, nomadic community, with socio-political perspectives that lead to unique appropriations of technology, often overlooked by mainstream HCI literature

We hypothesize that each group embodies unique values and attachments to public spaces, and sensor placements will reveal community and individual needs. Moreover, we predict that willingness to share and act on sensor data will in part reflect participants’ involvement in their particular community, as well as their perceived role in public spaces.
