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
Facilitating Mobile Music Sharing and Social Interaction with Push!Music
Push!Music is a novel mobile music listening and
sharing system, where users automatically receive
songs that have autonomously recommended
themselves from nearby players depending on similar
listening behaviour and music history. Push!Music
also enables users to wirelessly send songs between
each other as personal recommendations. We
conducted a two-week preliminary user study of
Push!Music, where a group of five friends used the
application in their everyday life. We learned for
example that the shared music in Push!Music became
a start for social interaction and that received songs in
general were highly appreciated and could be looked
upon as âtreatsâ
FITtogether: an 'average' activity tracker
In this paper we discuss an app we have implemented
for iOS and Android called FITtogether. The app counts
usersâ steps and enables them to compare these with
the average steps of all other users. We have trialed
the app over a two week period in the wild on usersâ
own devices. Our findings suggest that comparison with
an average leads to users feeling that they are
successful if they are above average, and that by
making a personal step count available to others only
as part of an average does not lead to anonymity and
identity concern
Services as Materials: Using Mashups for Research
Using existing services as development and research materials can greatly reduce development burdens. However, using mashups and existing services has consequences that go beyond the technical realm. We present our ongoing experience with developing and promoting a mobile mash-up implemented in the mobile web browser: Spotisquare. Spotisquare is a mash-up of the location-based service foursquare and music streaming service Spotify. We discuss advantages and tradeoffs of using existing services and the mobile mash-up process, including interaction model choices, as well as validity and representational issues
Pass the Ball: Enforced Turn-Taking in Activity Tracking
We have developed a mobile application called Pass The Ball that enables users to track, reflect on, and discuss physical activity with others. We followed an iterative design process, trialling a first version of the app with 20 people and a second version with 31. The trials were conducted in the wild, on users' own devices. The second version of the app enforced a turn-taking system that meant only one member of a group of users could track their activity at any one time. This constrained tracking at the individual level, but more successfully led users to communicate and interact with each other. We discuss the second trial with reference to two concepts: social-relatedness and individual-competence. We discuss six key lessons from the trial, and identify two high-level design implications: attend to "practices" of tracking; and look within and beyond "collaboration" and "competition" in the design of activity trackers
Seeing ethnographically: teaching ethnography as part of CSCW
While ethnography is an established part of CSCW research, teaching and
learning ethnography presents unique and distinct challenges. This paper discusses a
study of fieldwork and analysis amongst a group of students learning ethnography as part
of a CSCW & design course. Studying the studentsâ practices we explore fieldwork as a
learning experience, both learning about fieldsites as well as learning the practices of
ethnography. During their fieldwork and analysis the students used a wiki to collaborate,
sharing their field and analytic notes. From this we draw lessons for how ethnography
can be taught as a collaborative analytic process and discuss extensions to the wiki to
better support its use for collaborating around fieldnotes. In closing we reflect upon the
role of learning ethnography as a practical hands on â rather than theoretical â pursuit

Forget-me-not: History-less Mobile Messaging
Text messaging has long been a popular activity, and today
smartphone apps enable users to choose from a plethora of
mobile messaging applications. While we know a lot about
SMS practices, we know less about practices of messaging
applications. In this paper, we take a first step to explore
one ubiquitous aspect of mobile messaging â messaging
history. We designed, built, and trialled a mobile messaging
application without historyânamed forget-me-not. The
two-week trial showed that history-less messaging no
longer supports chit-chat as seen in e.g. WhatsApp, but is
still considered conversational and more âengagingâ.
Participants expressed being lenient and relaxed about what
they wrote. Removing the history allowed us to gain
insights into what uses history has in other mobile
messaging applications, such as planning events, allowing
for distractions, and maintaining multiple conversation
threads
Personal Tracking of Screen Time on Digital Devices
Numerous studies have tracked people's everyday use of digital devices, but without consideration of how such data might be of personal interest to the user. We have developed a personal tracking application that enables users to automatically monitor their 'screen time' on mobile devices (iOS and Android) and computers (Mac and Windows). The application interface enables users to combine screen time data from multiple devices. We trialled the application for 28+ days with 21 users, collecting log data and interviewing each user. We found that there is interest in personal tracking in this area, but that the study participants were less interested in quantifying their overall screen time than in gaining data about their use of specific devices and applications. We found that personal tracking of device use is desirable for goals including: increasing productivity, disciplining device use, and cutting down on use
