Out on the town: A socio-physical approach to the design of a context-aware urban guide

ABSTRACT

As urban environments become increasingly hybridized, mixing the social, built, and digital in interesting ways, designing for computing in the city presents new challenges—how do we understand such hybridization, and then respond to it as designers? Here we synthesize earlier work in human-computer interaction, sociology and architecture in order to deliberately influence the design of digital systems with an understanding of their built and social context of use. We propose, illustrate, and evaluate a multidisciplinary approach combining rapid ethnography, architectural analysis, design sketching, and paper prototyping. Following the approach we are able to provide empirically grounded representations of the socio-physical context of use, in this case people socializing in urban spaces. We then use this understanding to influence the design of a context aware system to be used while out on the town. We believe that the approach is of value more generally, particularly when achieving powerfully situated interactions is the design ambition.
