2nd workshop on research in the large. using app stores, wide distribution channels and big data in ubicomp research

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.


Mobile wellness: collecting, visualizing and interacting with personal health data

Mobile devices are now able to connect to a variety of sensors and provide personalized information to help people reflect on and improve their health. For example, pedometers, heart-rate sensors, glucometers, and other sensors can all provide real-time data to a variety of devices. Collecting and interacting with personal health or well-being data is a growing research area. This workshop will focus on the ways in which our mobile devices can aggregate and visualize these types of data and how these data streams can be presented to encourage interaction, increased awareness and positive behavior change.


Evolving relationships between social networks and stakeholder involvement in software projects

Software projects often fail because stakeholder communication and involvement are inadequate. This paper proposes a novel method to understand project social networks and their corresponding stakeholder involvement. The method uses five types of model social network, which represent various types of stakeholder activity in a project. It exploits evolutionary computation to correlate the social network of a real software project against each model. Experiments show that the real project most resembles the "rational" model where stakeholders who are more highly connected in the social network are more involved in the project.


Video interaction - making broadcasting a successful social media

Video has slowly been gaining popularity as a social media. We are now witnessing a step where capture and live broadcasts is released from the constraints of the desktop computer, which further accentuate issues such as video literacy, collaboration, hybridity, utility and privacy, that needs to be addressed in order to make video useful for large user groups.


NCATE standards for preparation of secondary computer science teachers

This special session serves two purposes. It provides a progress report on the revision of the NCATE Standards for the Preparation of Secondary Computer Science Teachers and seeks input from computing education professionals on the proposed revisions. The Standards and their role in evaluating teacher preparation programs will be explained, the proposed revision discussed, and process for providing input explained.


Understanding experience using dialogical methods: the case of serendipity

McCarthy and Wright's (2004) approach to understanding user experience provides a rich conceptual framework. In this paper, we report how this framework was used to guide the development of an approach to researching the richness of a particular experience - serendipity. Three themes were identified; life as lived and felt, the whole person, and dialogical sense making. These were used to help understand the key qualities of the strategy, tools and techniques that were required in the empirical study of the experience of serendipity. The paper explains this process and illustrates the depth of understanding that our choice of tools afforded. After describing the case study we offer some guidance on how to choose appropriate tools and methods for researching other types of experience.


So you want to run a film festival?

In an effort to promote awareness of and increase enrollment in the Division of Arts and Humanities, the Harvard Short Film Festival, a University-wide competition of three-minute short films about scholarly research and teaching, was launched in spring 2010.

Recent advances in media software now make it possible for someone equipped with just a personal computer, a digital camera, and some short software tutorials to compose compelling multimedia presentations that earlier required extensive training and costly equipment. Not the least of the changes implicit in this new technology is the promise of radically altered horizons in intellectual life---the development of new, more aesthetically rich modes of exposition in which the message expressed by words is blended with the implicit meanings and powerful affect conveyed by images and music.

This paper will outline the necessary marketing and technology considerations required to successfully support a film festival in an academic environment


Serendipitous family stories: using findings from a study on family communication to share family history

Storytelling and sharing family histories are important parts of what it means to "be" a family. Based on results from a study on intergenerational communication over a distance, we created the Serendipitous Family Stories system. The service allows family members to create visual and audio stories about places of importance in their lives and for their relatives to discover them serendipitously as they go about their lives. We will describe the motivation for the application and explain its functionality. Results from a field study are forthcoming.


Research in the large. using app stores, markets, and other wide distribution channels in Ubicomp research

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.


Parallel processing of data from very large-scale wireless sensor networks

In this paper we explore the problems of storing and reasoning about data collected from very large-scale wireless sensor networks (WSNs). Potential worldwide deployment of WSNs for, e.g., environmental monitoring purposes could yield data in amounts of petabytes each year. Distributed database solutions such as BigTable and Hadoop are capable of dealing with storage of such amounts of data. However, it is far from clear whether the associated MapReduce programming model is suitable for processing of sensor data. This is because typical applications MapReduce is used for, currently are relational in nature, whereas for sensing data one is usually interested in spatial structure of data instead. We show that MapReduce can indeed be used to develop such applications, and also describe in detail a general architecture for service platform for storing and processing of data obtained from massive WSNs.
