TUTORIAL 1 [full day]
The Fantasy and Reality of Conducting Ubiquitous Computing Research "In the Wild"
Timo Ojala and Vassilis Kostakos
This introductory level full-day tutorial provides a comprehensive insider view to a large multidisciplinary research program called UBI (UrBan Interactions, http://www.ubioulu.fi), and covers a range of issues related to conducting research in the wild.
The 'fantasy' of the UBI program has been to facilitate studies of ubiquitous computing systems in an authentic urban setting with sufficient scale and time span. Such studies are important because real world ubiquitous computing systems are culturally situated - as such they cannot be reliably assessed with lab studies detached from the real world context. By deploying the systems in authentic urban setting for longitudinal assessment by large numbers of real users, we wish to establish the technical and cultural readiness and the critical mass of users needed for determining whether the systems can be deemed '(un)successful'. The 'fantasy' has been pursued by establishing an open urban computing testbed comprising of rich computing resources such as interactive public displays, different types of wireless networks, and various middleware resources providing open APIs for application development. The testbed has been employed to deploy two different types of proof of concept prototypes, short-term small-scale DEMOs and long-term large-scale PILOTs of the ubiquitous city. Their evaluation provides valuable feedback and informs the researcher of the requirements of a particular application domain for the next design cycle. The 'reality' of the UBI program has been that the high external validity ensured by the longitudinal real-world deployment of the testbed and the prototypes comes with a substantial cost and methodological and practical difficulties.

TUTORIAL 2 [full day]
Building and Deploying Mobile Systems for Activity Recognition
Tanzeem Choudhury, Pedja Klasnja and Nicholas Lane
Sensor-equipped mobile devices are rapidly becoming a powerful platform for activity and context recognition. The ability to recognize user activities in everyday environments is driving innovations in healthcare, entertainment, social networking, gaming, transportation and citizen science. Although mobile sensing enables a wide range of applications, the different usage scenarios are unified by a set of common technical challenges related to: i) efficient and reliable sensing of people’s activities and environment; ii) accurate interpretation and classification of mobile sensor data; and iii) development and effective deployment of user applications based on sensing. Experts in machine learning, human-computer interaction and mobile systems have been addressing these challenges but typically approach the problem from only one perspective.
In this tutorial we will provide an interdisciplinary audience with the holistic view of the issues involved in the development and deployment of mobile systems for activity recognition. We will give an overview of the key ideas and approaches that have been proven successful in sensing, learning, and real-world deployments, as well as discuss some of the common pitfalls. The tutorial will be organized into a series of interactive sessions based around common usage scenarios that engage the audience via hand-on exercises that examine specific aspects of mobile activity recognition systems.
Tanzeem Choudhury is an assistant professor in the computer science department at Dartmouth and will be joining Cornell University in the fall of 2011. She directs the People-Aware Computing group that develops systems that can reason about human activities, interactions, and social networks in everyday environments.

His PhD thesis proposed community-guided learning techniques for mobile sensing systems; and demonstrated by effectively leveraging both individuals and their communities, these systems can cope with the diverse large-scale user populations found in the real world.
TUTORIAL 3 [full day]
Android for Ubiquitous Computing Researchers
Android smart-phones offer a huge opportunity to Ubiquitous
Computing researchers. Due to the fact that a great deal of
functionality can be accessed by applications running on an unmodified
handset they offer the opportunity for robust, large scale deployment
of UbiComp research ideas. The tutorial will focus on the development
of a simple location-based application ‘GeoMessanger’. This
application allows a user to post a geo-coded message and to receive
background notifications of new messages in their vicinity. The
tutorial will focus around a walk-through development of the
application and we require all delegates to bring along their own
laptops. Android development will take place using the Eclipse IDE
and thus delegates will be free to use Linux, Mac or Windows
platforms. Those delegates already owning Android devices will be
able to develop straight onto these devices, those without devices
will make use of the Android emulator. The workshop will also feature
a presentation on downloading, modifying and deploying new variants
the Android operating system. The tutorial aims to be accessible to
delegates from all programming backgrounds. Prior experience of the
Java programming language is desirable but not a prerequisite.
Andrew Rice is a University Lecturer in the Computer Laboratory at the University of Cambridge, UK. He has been using Android in both teaching and research since 2008. He teaches the Programming for Mobiles Course on the Advanced Computer Science MPhil1, and has run numerous summer projects with undergraduates developing Android applications2. He previously gave an Android tutorial at the International Conference on Mobile and Ubiquitous Multimedia (MUM) 2009. His research on the power consumption of Android devices was awarded best paper at PerCom20103.
TUTORIAL 4 [full day]
Title: Evaluating ubicomp applications in the field: The history, the techniques, and advice.
Gregory D. Abowd
As the technologies of ubiquitous computing mature, we are forced as a research community to go beyond proof of concept demonstrations of ubicomp applications and demonstrate what impact these systems have in the everyday lives of people. In this tutorial, I will provide an historical overview of important ubicomp evaluation efforts from the past that can serve as models of what to do and challenges that remain. I will also provide an overview of formative (in the process of designing a system to deploy) and summative (a real deployment evaluation) techniques that are particularly valuable for ubicomp application development and evaluation, with special attention paid to the role of ubicomp technology to facilitate evaluation. This tutorial will be aimed at ubicomp researchers (both students and faculty) who may be very familiar with ubicomp research topics but not familiar with human-computer interaction, interaction design or evaluation techniques. Simple group exercises will help to establish some confidence in conducting some of the techniques described. Notes and references will be provided, but those interested in preparing for this tutorial should get a copy of the book, Ubiquitous Computing Fundamentals, edited by John Krumm, and focus on the field studies chapter written by A.J. Brush.
Gregory Abowd is a Distinguished Professor in the School of Interactive Computing at the Georgia Inst. of Technology and has been an active ubicomp researcher since 1995. He has developed and evaluated a number of seminal ubicomp systems, including Classroom 2000, Cyberguide, the Personal Audio Loop, and a number of systems for use in the home and health spaces. Dr. Abowd is a co-author of a leading textbook in Human-Computer Interaction (with Alan Dix, Janet Finlay and Russell Beale) and has taught courses on HCI since 1994.
TUTORIAL 5 [half day]
Urban sensing using mobile phone network data
Over the past decade the development of digital networks and
operations has produced an unprecedented wealth of information
reflecting various aspects of urban life. In this framework, telecom
operators gather massive amount of data about how their users interact
or occupy the city's infrastructure.
During the tutorial I aim to outline some examples of data that can be
collected from telecommunication networks, and consider their
strengths and weaknesses in terms of accuracy, level of details, and
Moreover, I aim at introducing techniques for dealing with limitations
in granularity in both space and time, and pre-processing of mobile
phone network data to infer patterns related to human activities in
the city. Each of these techniques will be described in terms of
assumptions and limitations, and will be illustrated with examples
using real telecommunication datasets.
Finally, I aim to provide an overview of the challenges currently
being faced in this field.
