Description

Since Mark Weiser (1991) coined the term ubiquitous computing in the 1980’s, we have seen an immense research investment in ubiquitous (pervasive) computing (ubicomp for short). Most of the research has been conducted as short-term small-scale studies in lab settings, which have produced numerous scientific publications laying the existing theoretical foundation for ubicomp. As the ubiquitous computing technology has finally broken into the consumer market in form of powerful mobile terminals and ubiquitous high-speed wireless Internet access networks, the time is ripe for ubicomp research to break out into the real-world. However, not that many visible and lasting contributions from ubicomp research have emerged into the urban digital fabric. We argue that this worrying trend is at least partly due to the fact that we do not have universally accepted methodology and tradition for conducting ubicomp research in authentic real-world settings. Specifically, we do not have universally approved metrics for evaluating ubicomp systems deployed in real-world settings. Consequently, the mainstream ubicomp research favors measurable research typically conducted in usability labs using metrics and methodology inherited from the more traditional HCI field. This forces ubicomp researchers to conform to the mainstream (publish or perish is a strong motivator for anyone aspiring to an academic career), and discourages brave explorations into the real-world, which would be better equipped to make an impact on the society.

The objective of this proposal is to develop a standardized multidisciplinary framework for experimentally evaluating real-world ubicomp systems with increased external validity. The realization of the proposed evaluation framework is approached with multidisciplinary research involving computer science, economics, cultural anthropology and urban design. The framework is bootstrapped with the discipline specific metrics applicable for evaluating ubicomp systems and the underlying urban pervasive infrastructure. The metrics are iteratively validated and refined with empirical data collected from real-world ubicomp system deployments. To structure data collection and to achieve comparable data sets we develop templates specifying the conceptual elements of the framework for experiments. To ensure access to sufficient amounts of data and to involve the international research community in developing the framework we will be organizing international and national UBI-challenges. They will challenge the R&D community to innovate and deploy novel ubicomp systems atop our unique open urban computing testbed in the city of Oulu. The framework will also be exposed to independent external review at regular intervals. The data collection templates together with sample data sets collected during the research will be disseminated to the international community to support the adoption and validation of the framework.
