Living for the Global City: Mobile Kits, Urban Interfaces, and Ubicomp

Using ethnographic methods, 28 young professionals across the global cities of London, Los Angeles, and Tokyo were studied to understand in some detail what items they carried with them (their mobile kits) and how they used these items to access people, places, and services (through various urban interfaces). The findings are analyzed in terms of these cities as existing sites of ubiquitous information and communication technology (ICT) use. More specifically, findings are considered with respect to the prospects in these cities for ubicomp as a paradigm of trusted, environmentally embedded computing, as opposed to a wearable computing paradigm of individual self-sufficiency. Overall, at least for the young professional class studied, practices of urban interfacing were remarkably similar across all three cities studied, suggesting that ubicomp systems might be developed to address the range of urban concerns and to unburden and empower urbanites.
