UBI-Hotspot 1.0: Large-Scale Long-Term Deployment of Interactive Public Displays in a City Center

Abstract

We present the design, implementation, deployment and evaluation of 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.
