The rise of wireless networks and portable computing devices has been accompanied by an increasing interest in technology and mobility, and in the urban environment as a site of interaction. However, most investigations have taken a relatively narrow view of urban mobility. In consequence, design practice runs the risk of privileging particular viewpoints, forms of mobility, and social groups. We are interested in a view of mobility that reaches beyond traditional assumptions about the who, when, why, and what of mobility. Based on analytic perspectives from the social sciences and on empirical fieldwork in a range of settings, we outline an alternative view of technology and mobility with both analytic and design implications.
