Mobility is the Message: Experiments with Mobile Media Sharing
This thesis explores new mobile media sharing applications by building, deploying, and studying their use. While we share media in many different ways both on the web and on mobile phones, there are few ways of sharing media with people physically near us. Studied were three designed and built systems: Push!Music, Columbus, and Portrait Catalog, as well as a fourth commercially available system â Foursquare. This thesis offers four contributions: First, it explores the design space of co-present media sharing of four test systems. Second, through user studies of these systems it reports on how these come to be used. Third, it explores new ways of conducting trials as the technical mobile landscape has changed. Last, we look at how the technical solutions demonstrate different lines of thinking from how similar solutions might look today.
Through a Human-Computer Interaction methodology of design, build, and study, we look at systems through the eyes of embodied interaction and examine how the systems come to be in use. Using Goffmanâs understanding of social order, we see how these mobile media sharing systems allow people to actively present themselves through these media. In turn, using McLuhanâs way of understanding media, we reflect on how these new systems enable a new type of medium distinct from the web centric media, and how this relates directly to mobility.
While media sharing is something that takes place everywhere in western society, it is still tied to the way media is shared through computers. Although often mobile, they do not consider the mobile settings. The systems in this thesis treat mobility as an opportunity for design. It is still left to see how this mobile media sharing will come to present itself in peopleâs everyday life, and when it does, how we will come to understand it and how it will transform society as a medium distinct from those before. This thesis gives a glimpse at what this future will look like
Methods and ideas for the creation of 'transparent' music in the classroom
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Methods and ideas for the creation of âtransparentâ music in the classroom
The aims of this port-folio are as follows;
- To provide a coherent sequence of pieces and methods which can be used to create music in an educational context and also encourage students and teachers to develop their own creativity.
- To provide pieces which develop studentâs confidence in their own ability to
create music in a variety of ways including composition, improvisation and
creative leadership.
- To provide exercises and pieces which help to develop the listening and appreciation skills essential for ensemble musicmaking.
- To provide methods that enable the creation of âtransparent musicâ. This is
music in which the some, or all, of the decision making involved in the
creation of a piece is accessible and apparent to an audience during its
performance.
This submission consists of a teaching book containing thirteen pieces/exercises,
instructions giving guidance on their possible use in a teaching context and recorded
examples. Also included are separate instructions where appropriate for the use of
pieces in a concert or other non-educational setting and two essays giving context and
background information on the ideas behind the pieces
Virtual Conductor for String Quartet Practice
This paper presents a system that emulates an ensemble conductor for string quartets. This application has been developed as a support tool for individual and group practice, so that users of any age range can use it to further hone their skills, both for regular musicians and students
alike. The virtual conductor designed can offer similar indications to those given by a real ensemble conductor to potential users regarding beat times, dynamics, etc. The application developed allows the user to rehearse his/her
performance without the need of having an actual conductor present, and also gives access to additional tools to further support the learning/practice process, such as a tuner
or a melody evaluator. The system developed also allows for both solo practice and group practice. A set of tests were conducted to check the usefulness of the application as a practice support tool. A group of musicians from the
Chamber Orchestra of Malaga including an ensemble conductor tested the system, and reported to have found it a very useful tool within an educational environment and that it helps to address the lack of this kind of educational tools in a self-learning environment.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03- 02 and Project No. IPT-2011-0885-430000 and by the Ministerio de Industria, Turismo y Comercio under Project No. TSI-090100-2011-25
Designing and evaluating mobile multimedia user experiences in public urban places: Making sense of the field
The majority of the worldâs population now lives in cities (United Nations, 2008) resulting in an urban densification requiring people to live in closer proximity and share urban infrastructure such as streets, public transport, and parks within cities. However, âphysical closeness does not mean social closenessâ (Wellman, 2001, p. 234). Whereas it is a common practice to greet and chat with people you cross paths with in smaller villages, urban life is mainly anonymous and does not automatically come with a sense of community per se. Wellman (2001, p. 228) defines community âas networks of interpersonal ties that provide sociability, support, information, a sense of belonging and social identity.â While on the move or during leisure time, urban dwellers use their interactive information communication technology (ICT) devices to connect to their spatially distributed community while in an anonymous space. Putnam (1995) argues that available technology privatises and individualises the leisure time of urban dwellers. Furthermore, ICT is sometimes used to build a âcocoonâ while in public to avoid direct contact with collocated people (Mainwaring et al., 2005; Bassoli et al., 2007; Crawford, 2008). Instead of using ICT devices to seclude oneself from the surrounding urban environment and the collocated people within, such devices could also be utilised to engage urban dwellers more with the urban environment and the urban dwellers within. Urban sociologists found that âwhat attracts people most, it would appear, is other peopleâ (Whyte, 1980, p. 19) and âpeople and human activity are the greatest object of attention and interestâ (Gehl, 1987, p. 31). On the other hand, sociologist Erving Goffman describes the concept of civil inattention, acknowledging strangersâ presence while in public but not interacting with them (Goffman, 1966). With this in mind, it appears that there is a contradiction between how people are using ICT in urban public places and for what reasons and how people use public urban places and how they behave and react to other collocated people. On the other hand there is an opportunity to employ ICT to create and influence experiences of people collocated in public urban places. The widespread use of location aware mobile devices equipped with Internet access is creating networked localities, a digital layer of geo-coded information on top of the physical world (Gordon & de Souza e Silva, 2011). Foursquare.com is an example of a location based 118 Mobile Multimedia â User and Technology Perspectives social network (LBSN) that enables urban dwellers to virtually check-in into places at which they are physically present in an urban space. Users compete over âmayorshipsâ of places with Foursquare friends as well as strangers and can share recommendations about the space. The research field of Urban Informatics is interested in these kinds of digital urban multimedia augmentations and how such augmentations, mediated through technology, can create or influence the UX of public urban places. âUrban informatics is the study, design, and practice of urban experiences across different urban contexts that are created by new opportunities of real-time, ubiquitous technology and the augmentation that mediates the physical and digital layers of people networks and urban infrastructuresâ (Foth et al., 2011, p. 4). One possibility to augment the urban space is to enable citizens to digitally interact with spaces and urban dwellers collocated in the past, present, and future. âAdding digital layer to the existing physical and social layers could facilitate new forms of interaction that reshape urban lifeâ (Kjeldskov & Paay, 2006, p. 60). This methodological chapter investigates how the design of UX through such digital placebased mobile multimedia augmentations can be guided and evaluated. First, we describe three different applications that aim to create and influence the urban UX through mobile mediated interactions. Based on a review of literature, we describe how our integrated framework for designing and evaluating urban informatics experiences has been constructed. We conclude the chapter with a reflective discussion on the proposed framework
Resonances: The sound of performance
It is a hot summer night in August 2013, as the audience gathers near the entrance of the large Gray Hall at the south side of the former coal mine Göttelborn (Germany). The sun has set, and there is only the gray light of dusk in the performance space inside, streaming through the large glass façade, falling onto a small array of stones laid out on the floor. Additional light from a video projector streams over the stones, and a tiny figure of a dancer is seen crawling over rocks, moving in the strange, a-syncopated rhythm of jump cuts. Slowly the sound of rocks scratching against a stone surface begins to be heard, it will remain the only sound for a while, then Japanese instrumentalist Emi Watanabe steps into the empty space with her flute
Dancing to the Partisan Beat: A First Analysis of Political Communication on TikTok
TikTok is a video-sharing social networking service, whose popularity is
increasing rapidly. It was the world's second-most downloaded app in 2019.
Although the platform is known for having users posting videos of themselves
dancing, lip-syncing, or showcasing other talents, user-videos expressing
political views have seen a recent spurt. This study aims to perform a primary
evaluation of political communication on TikTok. We collect a set of US
partisan Republican and Democratic videos to investigate how users communicated
with each other about political issues. With the help of computer vision,
natural language processing, and statistical tools, we illustrate that
political communication on TikTok is much more interactive in comparison to
other social media platforms, with users combining multiple information
channels to spread their messages. We show that political communication takes
place in the form of communication trees since users generate branches of
responses to existing content. In terms of user demographics, we find that
users belonging to both the US parties are young and behave similarly on the
platform. However, Republican users generated more political content and their
videos received more responses; on the other hand, Democratic users engaged
significantly more in cross-partisan discussions.Comment: Accepted as a full paper at the 12th International ACM Web Science

Discourse Analysis as Potential for Re-Visioning Music Education
Discourse analysis holds great potential for re-visioning the field of music education. This paper explores works from Foucault, Blommaert, Scollon and Scollon, as well as others, to suggest a theoretical and methodological approach to analyzing discourse in settings of music transmission that takes into consideration who we are, what we do, and how we do it. Discourse is defined in this paper as meaningful, mediated language-in-place. By analyzing acts of speech as well as cultural objects (such as instruments, mallets, and bows) and concepts (such as a conducting gestures or solfege syllables) used as mediational means in situ, we can reveal how discursive sources of power dominance, inequality, and bias are initiated, perpetuated, (re)produced, and transformed in sites of music transmission. Analyzing such models may help develop a more flexible way of understanding and visioning music educationâone that blurs boundaries between musics, ways of knowing music, and spaces where musicking takes place
Ambient Gestures
We present Ambient Gestures, a novel gesture-based system designed to support ubiquitous âin the environmentâ interactions with everyday computing technology. Hand gestures and audio feedback allow users to control computer applications without reliance on a graphical user interface, and without having to switch from the context of a non-computer task to the context of the computer. The Ambient Gestures system is composed of a vision recognition software application, a set of gestures to be processed by a scripting application and a navigation and selection application that is controlled by the gestures. This system allows us to explore gestures as the primary means of interaction within a multimodal, multimedia environment. In this paper we describe the Ambient Gestures system, define the gestures and the interactions that can be achieved in this environment and present a formative study of the system. We conclude with a discussion of our findings and future applications of Ambient Gestures in ubiquitous computing
