Mobile Sensing Systems

[EN] Rich-sensor smart phones have made possible the recent birth of the mobile sensing research area as part of ubiquitous sensing which integrates other areas such as wireless sensor networks and web sensing. There are several types of mobile sensing: individual, participatory, opportunistic, crowd, social, etc. The object of sensing can be people-centered or environment-centered. The sensing domain can be home, urban, vehicular Currently there are barriers that limit the social acceptance of mobile sensing systems. Examples of social barriers are privacy concerns, restrictive laws in some countries and the absence of economic incentives that might encourage people to participate in a sensing campaign. Several technical barriers are phone energy savings and the variety of sensors and software for their management. Some existing surveys partially tackle the topic of mobile sensing systems. Published papers theoretically or partially solve the above barriers. We complete the above surveys with new works, review the barriers of mobile sensing systems and propose some ideas for efficiently implementing sensing, fusion, learning, security, privacy and energy saving for any type of mobile sensing system, and propose several realistic research challenges. The main objective is to reduce the learning curve in mobile sensing systems where the complexity is very high.This work has been partially supported by the "Ministerio de Ciencia e Innovacion", through the "Plan Nacional de I+D+i 2008-2011" in the "Subprograma de Proyectos de Investigacion Fundamental", project TEC2011-27516, and by the Polytechnic University of Valencia, through the PAID-05-12 multidisciplinary projects.Macias Lopez, EM.; Suarez Sarmiento, A.; Lloret, J.

Soundscapes of the Urban Past: Staged Sound as Mediated Cultural Heritage

We cannot simply listen to our urban past. Yet we encounter a rich cultural heritage of city sounds presented in text, radio and film. How can such "staged sounds" express the changing identities of cities? This volume presents a collection of studies on the staging of Amsterdam, Berlin and London soundscapes in historical documents, radio plays and films, and offers insights into themes such as film sound theory and museum audio guides. In doing so, this book puts contemporary controversies on urban sound in historical perspective, and contextualises iconic presentations of cities. It addresses academics, students, and museum workers alike

Next generation analytics for open pervasive display networks

Public displays and digital signs are becoming increasingly widely deployed as many spaces move towards becoming highly interactive and augmented environments. Market trends suggest further significant increases in the number of digital signs and both researchers and commercial entities are working on designing and developing novel uses for this technology. Given the level of investment, it is increasingly important to be able to understand the effectiveness of public displays. Current state-of-the-art analytics technology is limited in the extent to which it addresses the challenges that arise from display deployments becoming open (increasing numbers of stakeholders), networked (viewer engagement across devices and locations) and pervasive (high density of displays and sensing technology leading to potential privacy threats for viewers). In this thesis, we provide the first exploration into achieving next generation display analytics in the context of open pervasive display networks. In particular, we investigated three areas of challenge: analytics data capture, reporting and automated use of analytics data. Drawing on the increasing number of stakeholders, we conducted an extensive review of related work to identify data that can be captured by individual stakeholders of a display network, and highlighted the opportunities for gaining insights by combining datasets owned by different stakeholders. Additionally, we identified the importance of viewer-centric analytics that use traditional display-oriented analytics data combined with viewer mobility patterns to produce entirely new sets of analytics reports. We explored a range of approaches to generating viewer-centric analytics including the use of mobility models as a way to create 'synthetic analytics' - an approach that provides highly detailed analytics whilst preserving viewer privacy. We created a collection of novel viewer-centric analytics reports providing insights into how viewers experience a large network of pervasive displays including reports regarding the effectiveness of displays, the visibility of content across the display network, and the visibility of content to viewers. We further identified additional reports specific to those display networks that support the delivery of personalised content to viewers. Additionally, we highlighted the similarities between digital signage and Web analytics and introduced novel forms of digital signage analytics reports created by leveraging existing Web analytics engines. Whilst the majority of analytics systems focus solely on the capture and reporting of analytics insights, we additionally explored the automated use of analytics data. One of the challenges in open pervasive display networks is accommodating potentially competing content scheduling constraints and requirements that originate from the large number of stakeholders - in addition to contextual changes that may originate from analytics insights. To address these challenges, we designed and developed the first lottery scheduling approach for digital signage providing a means to accommodate potentially conflicting scheduling constraints, and supporting context- and event-based scheduling based on analytics data fed back into the digital sign. In order to evaluate the set of systems and approaches presented in this thesis, we conducted large-scale, long-term trials allowing us to show both the technical feasibility of the systems developed and provide insights into the accuracy and performance of different analytics capture technologies. Our work provides a set of tools and techniques for next generation digital signage analytics and lays the foundation for more general people-centric analytics that go beyond the domain of digital signs and enable unique analytical insights and understanding into how users interact across the physical and digital world

Authenticity and the Use of Multimedia at Cultural Tourist Attractions

Within the area of cultural attractions new developments in modern technologies have brought changes as to how culture and heritage are presented and interpreted. This has evoked debates whether such sites can still be regarded as authentic. While researchers have investigated these issues on a theoretical basis, the perception and experience of authenticity as well as the use of modern interpretative tools have been treated separately and still lack empirical investigation. Therefore, this study explores the perceptions and experiences of authenticity at cultural attractions where modern technologies are applied. The central research questions are: (1) How can the key concepts of authenticity, multimedia and experience of cultural attractions be brought into an integrated measurable model? (2) What are the determinants of an authentic attraction and an authentic experience? (3) What is the role of multimedia in the visitor experience of a cultural attraction? In order to provide answers to these research questions a combination of qualitative and quantitative methods was applied. In the first stage, focus-group discussions, expert interviews as well as a small scale quantitative study at “Ceol” – The Traditional Irish Music Centre were conducted. Based on these findings and a thorough literature review a Structural Equation Model was developed. This model incorporates visitor satisfaction, site specific attributes (including multimedia and perception of authenticity) and experiential aspects (i.e. experienced object-, personal-, and social authenticity). The model was tested using data from different sites in two different cities. These included The Guinness Storehouse in Dublin, a modern-type attraction in which multimedia constitutes an integral element of the experience, and the Sisi Museum in Vienna, an old established museum where audio-guides are offered. II The findings revealed that object- and personal authenticity proved to be important concepts. However, the role of experienced social authenticity needs further investigation. The results also show that technology does not undermine the authenticity of a site - many visitors prefer to experience an attraction without such tools and in addition the use of an audio-guide did not lead to a higher satisfaction with the site. The suggested model can be regarded as a promising basis for further modelling the visitor experience at cultural attractions

Unmanned Aircraft Systems in the Cyber Domain

Unmanned Aircraft Systems are an integral part of the US national critical infrastructure. The authors have endeavored to bring a breadth and quality of information to the reader that is unparalleled in the unclassified sphere. This textbook will fully immerse and engage the reader / student in the cyber-security considerations of this rapidly emerging technology that we know as unmanned aircraft systems (UAS).

Clubbing: otherness and the politics of experience

This thesis investigates experiences of contemporary club and dance cultures in the context of postmodern aestheticisation. Its object of study is the phantasmatic and discursive complex of otherness, transgression and freedom in which contemporary British club and dance cultures are embedded. It argues that clubbing experiences are fabricated through this complex of otherness, which articulates a politics, of experience. This refers to contexts that structure experiences of dance cultures. In this respect, the thesis considers the contexts of class, gender and sexuality, structures of the production and consumption of clubbing, the institutional regulation and ordering of club spaces and media discourses and imagery. In analysing socially contextualised meanings of this otherness it examines how these become relevant for the construction of identity. The theoretical agenda of the thesis is to explore aestheticisation as a condition for and as a form of identity construction. This engages with changing modes of reflexivity in the construction of reality and reformulates the issues of style, identity and authenticity. The empirical analysis focuses on modes of reflexivity in constructing realities of sexuality, body and self. Research of this study was carried out in London. The qualitative research design comprised narrative interviewing and ethnographic participation in clubs in central London. A criterion for sampling and for the selection of clubs and interviewees was the dimension of sexuality and the sexual differentiation and codification of club spaces. The interview sample consists of twenty-three interviews with people of mixed genders, sexualities and cultural, national backgrounds
