ABSTRACT We present a unique urban computing testbed for studying the utilization of ubiquitous computing technology in the public urban space of a city center. The testbed comprises of a wide range of pervasive computing infrastructure and different middleware resources. We demonstrate the applicability and benefits of the testbed in evaluating technology pilots and prototyping new ubiquitous services in real-world urban setting. We conclude with a discussion on the challenges in deploying this kind of a large-scale testbed in a public urban space. We introduce a unique urban computing testbed in the City of Oulu in northern Finland, just 200 km south of the Arctic Circle. With 140000 citizens Oulu is the sixth largest city in Finland. The Oulu region has strong ICT competence in 14000 ICT jobs and the largest regional R&D expenditure per capita in Finland. In the late 1990's the Wired Magazine ranked Oulu as the number three 'silicon valley' in the world. The long-term goal of our testbed is to provide open horizontal resources for building incremental functional prototypes of a future ubiquitous city. There networked computing devices are seamlessly embedded into the urban space, turning it into a smart space providing different interaction modalities with the physical, virtual and social spaces. The utilization of ubiquitous computing technologies in urban space is studied by the multidisciplinary field of urban computing. It is driven by two important and related trends, urbanization and increasing deployment of pervasive computing infrastructure in the urban areas. The mainstream research on ubiquitous computing suffers from a distinct lack of longitudinal, real-world case studies of system usage. The vast majority of research consists of studies that typically last a few days or weeks at best. Further, from the viewpoint of urban computing the studies are often executed in artificial settings such as labs and university campuses. While the immense research effort has produced numerous publications laying the theoretical foundation, few visible and lasting contributions to the urban digital fabric have emerged. This lack of coherent progress motivated the 2005 UbiApps workshop at Pervasive 2005, where 25 researchers were

    ABSTRACT: The UrBan Interactions (UBI) research program, coordinated by the University of Oulu, has created a middleware layer on top of the panOULU wireless network and opened it up to ubiquitous-computing researchers, offering opportunities to enhance and facilitate communication between citizens and the government.

    ABSTRACT: We present the design, implementation, deployment and evaluation of a novel urban computing infrastructure called UBI-hotspot. It is effectively a large interactive public display embedded with other computing resources. We have deployed a network of UBI-hotspots around downtown Oulu, Finland, to establish a public laboratory for conducting experimental ubiquitous computing research in authentic urban setting with diverse real users and with sufficient scale and time span. We focus on the first version of the UBI-hotspot which offers a wide range of services via different interaction modalities. We analyze the usage and user acceptance of the UBI-hotspots from qualitative and quantitative data collected over a period of eight months. Our first observations show that this type of infrastructure may be a useful addition to the urban space.

    ABSTRACT: In this paper, we suggest utilizing modern social networking services for building versatile applications for interactive public displays. We demonstrate the functionality and potential of this approach by presenting a set of services deployed on top of a network of public displays, utilized in a longitudinal study in an authentic city setting. We further propose utilizing users' personal online profiles for building personalized and appealing public social services, and suggest that this may enhance the attractiveness of interactive public displays. Results of this study indicate that using interactive public displays is inherently a social event, and that services supporting group use and sociality succeed in urban smart spaces.
