    Mobile Water Payment Innovations in Urban Africa

    This study assess mobile payment options for water service bills in four urban African contexts. Systems are evaluated to identify differences in adoption levels and motivations and barriers to uptake; how costs are distributed among water service providers, mobile network operators, and customers; and mobile payment applications and designs. Data was collected through interviews with water service providers, mobile network operators and service regulators, as well as a household survey in one of the study regions and the aid of World Bank and national water regulator data. Mobile water payment adoption rates were low, but there was also evidence that key barriers such as limited awareness, lack of physical proof of payment, and high transaction tariffs, could be overcome. Increased mobile water payment is found to result in considerable savings in time and money for consumers, revenue for mobile network operators, and perhaps most importantly, strengthened finances for water service providers to improve their ability to provide sustainable service

    Gophers: socially oriented pervasive gaming

    Get PDF
    Gophers is an open-ended gaming environment which relies on location data, user generated content and player interactions to shape gameplay. It seeks to investigate social collaboration within localised and distributed gaming communities, the potential of pervasive gaming as a technique to collect useful data about the physical world and additionally, use of novel peer-judging methods to allow self-governing of the game world. In this paper, we introduce the game in its current state and provide an overview of early test results

    This is the author's accepted manuscript. The final publication is available at Springer via http://dx.doi.org/10.1007/s00779-013-0698-3. Copyright @ Springer-Verlag London 2013.Context-sensitive (or aware) applications have, in recent years, moved from the realm of possibilities to that of ubiquity. One exciting research area that is still very much in the realm of possibilities is that of cloud computing, and in this paper, we present our work, which explores the overlap of these two research areas. Accordingly, this paper explores the notion of cross-source integration of cloud-based, context-aware information in ubiquitous computing through a developed prototypical solution. Moreover, the described solution incorporates remote and automatic configuration of Android smartphones and advances the research area of context-aware information by harvesting information from several sources to build a rich foundation on which algorithms for context-aware computation can be based. Evaluation results show the viability of integrating and tailoring contextual information to provide users with timely, relevant and adapted application behaviour and content

    Spending time with money: from shared values to social connectivity

    This article has been made available through the Brunel Open Access Publishing Fund.There is a rapidly growing momentum driving the development of mobile payment systems for co-present interactions, using near-field communication on smartphones and contactless payment systems. The design (and marketing) imperative for this is to enable faster, simpler, effortless and secure transactions, yet our evidence shows that this focus on reducing transactional friction may ignore other important features around making payments. We draw from empirical data to consider user interactions around financial exchanges made on mobile phones. Our findings examine how the practices around making payments support people in making connections, to other people, to their communities, to the places they move through, to their environment, and to what they consume. While these social and community bonds shape the kinds of interactions that become possible, they also shape how users feel about, and act on, the values that they hold with their co-users. We draw implications for future payment systems that make use of community connections, build trust, leverage transactional latency, and generate opportunities for rich social interactions

    Challenges in context-aware mobile language learning: the MASELTOV approach

    Get PDF
    Smartphones, as highly portable networked computing devices with embedded sensors including GPS receivers, are ideal platforms to support context-aware language learning. They can enable learning when the user is en-gaged in everyday activities while out and about, complementing formal language classes. A significant challenge, however, has been the practical implementation of services that can accurately identify and make use of context, particularly location, to offer meaningful language learning recommendations to users. In this paper we review a range of approaches to identifying context to support mobile language learning. We consider how dynamically changing aspects of context may influence the quality of recommendations presented to a user. We introduce the MASELTOV project’s use of context awareness combined with a rules-based recommendation engine to present suitable learning content to recent immigrants in urban areas; a group that may benefit from contextual support and can use the city as a learning environment

    Locational wireless and social media-based surveillance

    Get PDF
    The number of smartphones and tablets as well as the volume of traffic generated by these devices has been growing constantly over the past decade and this growth is predicted to continue at an increasing rate over the next five years. Numerous native features built into contemporary smart devices enable highly accurate digital fingerprinting techniques. Furthermore, software developers have been taking advantage of locational capabilities of these devices by building applications and social media services that enable convenient sharing of information tied to geographical locations. Mass online sharing resulted in a large volume of locational and personal data being publicly available for extraction. A number of researchers have used this opportunity to design and build tools for a variety of uses – both respectable and nefarious. Furthermore, due to the peculiarities of the IEEE 802.11 specification, wireless-enabled smart devices disclose a number of attributes, which can be observed via passive monitoring. These attributes coupled with the information that can be extracted using social media APIs present an opportunity for research into locational surveillance, device fingerprinting and device user identification techniques. This paper presents an in-progress research study and details the findings to date
