Summary: 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.

Summary: 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 -- messaging history. We designed, built, and
trialled a mobile messaging application without history named 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 'engaging'. 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.

Summary: We have conducted a video study of households in Scotland with cohabiting
students and young professionals. In this paper we unpack five examples of how
mobile devices are used by people watching television. In the examples we
explore how screens are used together (a) in a physical ecology, (b) in an
embodied way, (c) in an orderly way, and (d) with respect to others. We point
out that mobile devices are routinely used to access media that is unconnected
and unrelated to media on television, for example for sending and receiving
messages, browsing social media, and browsing websites. We suggest that mobile
devices are not used to directly enhance television programmes, but to enhance
leisure time. We suggest that it is important, when considering mobile devices
as second screens, not just to treat these as a design topic, but to pay
attention to how they are interactionally integrated into the living room.

Summary: 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.

Summary: This paper characterises the use of activity trackers as "lived
informatics". This characterisation is contrasted with other discussions of
personal informatics and the quantified self. The paper reports an interview
study with activity tracker users. The study found: people do not logically
organise, but interweave various activity trackers, sometimes with ostensibly
the same functionality; that tracking is often social and collaborative rather
than personal; that there are different styles of tracking, including goal
driven tracking and documentary tracking; and that tracking information is
often used and interpreted with reference to daily or short term goals and
decision making. We suggest there will be difficulties in personal informatics
if we ignore the way that personal tracking is enmeshed with everyday life and
people's outlook on their future.

Summary: With the launch of 'app stores' on several mobile platforms and the great
uptake of smartphones among the general population, researchers have begun
utilising these distribution channels to deploy research software to large
numbers of users. Previous Research In The Large workshops have sought to
establish base-line practice in this area. We have seen the use of app stores
as being successful as a methodology for gathering large amounts of data,
leading to design implications, but we have yet to explore the full potential
for this data's use and interpretation. How is it possible to leverage the
practices of large-scale research, beyond the current approaches, to more
directly inform future designs? We propose that the time is right to
re-energise discussions on large-scale research, looking further than the basic
methodological issues and assessing the potential for informing the design of
new mobile software.

Summary: Online services provide a range of opportunities for understanding human
behaviour through the large aggregate data sets that their operation collects.
Yet the data sets they collect do not unproblematically model or mirror the
world events. In this paper we use data from Foursquare, a popular location
check-in service, to argue for the importance of analysing social media as a
communicative rather than representational system. Drawing on logs of all
Foursquare check-ins over eight weeks we highlight four features of
Foursquare's use: the relationship between attendance and check-ins, event
check-ins, commercial incentives to check-in, and lastly humorous check-ins
These points show how large data analysis is affected by the end user uses to
which social networks are put.

Summary: With the proliferation of app stores and the advancement of mobile devices,
research that might have only been tested with a dozen participants in the past
can now be released to millions. This offers huge opportunities, but also
requires adaptations of existing methods in dealing with large deployments and
making sense of large data sets. This workshop provides a forum for researchers
to exchange experiences and strategies for wide distribution of applications as
well as gathering and analyzing large scale data sets.

Summary: Location-sharing services have a long history in research, but have only
recently become available for consumers. Most popular commercial
location-sharing services differ from previous research efforts in important
ways: they use manual 'check-ins' to pair user location with semantically named
venues rather than tracking; venues are visible to all users; location is
shared with a potentially very large audience; and they employ incentives. By
analysis of 20 in-depth interviews with foursquare users and 47 survey
responses, we gained insight into emerging social practices surrounding
location-sharing. We see a shift from privacy issues and data deluge, to more
performative considerations in sharing one's location. We discuss performance
aspects enabled by check-ins to public venues, and show emergent, but sometimes
conflicting norms (not) to check-in.

Summary: As new technologies are appropriated by researchers, the community must come
to terms with the evolving ethical responsibilities we have towards
participants. This workshop brings together researchers to discuss the ethical
issues of running large-scale user trials, and to provide guidance for future
research. Trials of the scale of 10s or 100s of thousands of participants offer
great potential benefits in terms of attracting users from vastly different
geographical and social contexts, but raise significant ethical challenges. The
inability to ensure user understanding of the information required to provide
informed consent and problems involved in making users aware of the
implications of the information being collected all beg the question: how can
researchers ethically take advantage of the opportunities these new
technologies afford?

Summary: This paper presents the φ2 ('Phi-square') Scanner and φ2
Barcode Generator -- an exploration of physical check-ins for location-based
services. The system uses 2D barcodes to retrieve and share semantic location
information. Users can scan barcodes at venues that activate a location-based
application with the corresponding venue page. This system overcomes problems
arising when users have to select their location manually. We expect an
enhanced user experience using physical artefacts in location-based services.

Summary: Current mobile browser capabilities make it possible to quickly develop
advanced mobile location based services without having to write device specific
software, or build custom hardware. We here describe three web applications
exploring using location within mobile browsers (TågAlong, NearMe and
LocalURL). These explorations show clear potential for using geolocation in the
web browser in order to reach a larger user base, with a greater variety of
devices, thus allowing for UbiComp researchers to explore the effects of
specific services and applications on a larger scale. We discuss the services,
as well as the potential and challenges with using the user's location directly
in the browser.

Summary: The mobile phones that people use in their daily lives now run advanced
applications and come equipped with sensors once only available in custom
hardware in UbiComp research. At the same time application distribution has
become increasingly simple due to the proliferation of app stores and the like.
Evaluation and research methods have to be adapted to this new context to get
the best data and feedback from wide audiences. However, an overview of
successful strategies to overcome research challenges inherent to wide
deployment is not yet available. App store platform characteristics, devices,
reaching target users, new types of evaluation data and dynamic, heterogeneous
usage contexts have to be dealt with. This workshop provides a forum for
researchers and developers to exchange experiences and strategies for wide
distribution of applications. We aim at building an understanding of the
opportunities of various distribution channels and obstacles involved in a
research context.

Summary: Mobile technology has turned the traditionally collective activity of
enjoying music into an often private one. New technologies such as wireless ad
hoc networks have the potential to re-connect listeners who are now separated
by headphones. We report on a field study of Push!Music, a novel mobile music
sharing system. Push!Music allows both manual and automatic sharing of music
between users through ad hoc wireless networking, and also provides a social
awareness of other users nearby. The system was used by 13 subjects for three
weeks. In post-study interviews, we identified four categories of results:
social awareness, sharing music with friends, sharing music with strangers, and
sharing automatically. Based on this, we present implications for design that
can be applied not only to mobile music sharing systems, but to mobile media
sharing in general: Allow division into active and passive use; enhance the
awareness of who, where and when; support reciprocity; and finally, support
identity and impression management.

Summary: 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 students'
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 -- rather
than theoretical -- pursuit.

Summary: We present a mode where media (e.g. music files) are autonomous entities
that carry their own individual information. Our goal is to turn such files
into autonomous, rule-following agents capable of building their own identities
from interactions with other agents and users. We are exploring how
collaborative filtering-like behaviour could emerge out of large ensembles of
interacting agents, which are distributed over mobile devices in socia
networks. We have implemented a first version of the mode in the form of a
music player application for mobile devices, called Push!Music. This system
takes advantage of active recommendations as we as implicit user activity to
build a profile for each media file.
