Presentation: The co-evolution of taxi drivers and their in-car navigation systems

Yesterday, I presented at the 2008 Association of American Geographers Annual Meeting, the preliminary results of my ethnographic study on the use, adoption, and appropriation of satellite navigation systems by taxi drivers in Barcelona (slides). The abstract of the paper “The co-evolution of taxi drivers and their in-car navigation systems” co-authored with Josep Blat goes as follows:

In recent years, the relative market success of in-car navigation systems has symbolized the emergence of location-based services for wayfinding. This market success creates the opportunity to learn from real-world use of current location-aware systems in order to inform the design of future applications. With this aim, we are using an ethnographic approach to study the different ways taxi drivers rely on their navigation system. This work describes how location technologies impact the wayfinding practices and also how practices influence the appropriation of navigation systems. This co-evolution goes from the acquisition and setup of a navigation system to mastering the system shortcomings and limitations. Next, we study the reasons upon which a driver selects among the different modes of a navigation system and the other artifacts and tools (e.g. maps, street directories, landmarks) he or she uses for location awareness and wayfinding. Moreover, we analyze the role of context in this dynamics, i.e., where and when a driver accesses location information from the system, the external supports and the surrounding environment. We present the findings that emerged from 12 interviews augmented by in-car observations within the community of taxi drivers of the city of Barcelona, Spain. This community forms a massive population of early adopters of in-car navigation systems with a strong past practice of relying on mobile technologies and maps to support their work.
