Social TV has been an active area of research for more than a decade now, but most research has focused on interaction between remote participants, either through direct communication or more indirect e.g. in the form of social recommendations. However, an issue that has been mostly neglected in social TV research is how to deal with multiple co-located users in the home. This workshop addresses that gap by investigating possible social TV services for multiple users in the home. The objective is to bring together researchers and practitioners working on different aspects of multi-user services for social television including multiple devices: user research, prototype design, technical implementation, system scalability, business models, etc.

Despite of the establishment of digital television services, audience measurement and other media analysis still rely on obsolete and usually expensive techniques that date back to the analog era. Moreover, the introduction of interactive services into TV terminal devices is not adequately considered in such market researches. The analysis of both viewer's audience and interactive behavior can thrive this market, which still didn't come up with killer interactive applications. This paper proposes and compares two approaches for the capture of viewer's audience and interactivity behavior in Interactive TV systems (iTV). The first approach for data capturing relies on new extensions to existing iTV middleware standards, whereas the second one just makes use of software features commonly supported by those standards. Captured data should be sent to aggregation servers that allow multiple reports to be generated and made available online for real time tracking. Aggregation servers and software tools are components of the Interaction and Audience Analysis Service Provider (IAASP), which is also described and implemented in this work.

Make It So (Rosenfeld Media, 2012) explores the speculative interfaces seen in science fiction movies and television shows. The authors have developed a model that traces lines of influence between these sci-fi examples and design in the real world, and use this model as a scaffold to investigate how the depiction of technologies evolve over time, how fictional interfaces influence those in the real world, and what lessons interface designers can learn through this process. Only described briefly in the book, this keynote walks the audience through this model in detail, highlighting video clip examples throughout.

Catch-up TV services on the Web have facilitated time-shifted TV viewing. However, there is limited information about user search behavior with regard to recently time-shifted versus archival TV content. We deployed two distinct content-based web services to explore information retrieval of time-shifted TV content. The first web service is based on a browsing metaphor, while the second is based on free text content search metaphor. We analyzed more than 5000 user sessions from 12 months of logs and found that the programs accessed via browsing categorized program content summaries were typically less than one week old. In contrast, the programs accessed via free text search on subtitle content were typically more than a week old. Our findings provide a first assessment of user behavior in accessing time-shifted and archival TV content. Further research should develop the user experience for content-based TV access and explore the sharing patterns of archival TV content on social networks.

The popularity of TV worldwide and particularly in emergent markets opened a window of opportunities for many people working with Interactive Digital TV and related topics. New solutions and new business approaches are supposed to rise from this scenario, creating many new job opportunities. The main goal of this workshop is to bring together researchers, educators, and industry related people working in the deployment of solutions for DTV Systems and associated Applications in emergent countries. Along this workshop, discussion about the adopted policies, technologies, state-of-the-art, middleware solutions, content models, interactivity systems, and future applications in the researchers' countries are going to be the main action. Indeed, it is going to be a global forum where the participants will be able to identify common issues and exchange experiences, sharing the adopted solutions for common known problems. The organizers hope to keep building and maintaining a research network that will help people working in developing countries to increase their technical contributions in Interactive Digital TV related issues.

Posting comments on social networks using second screen devices (e.g., tablets) while watching TV is becoming very common. The simplicity of microblogs makes Twitter among the preferred social services used by the TV audience to share messages about TV shows and movies. Thus, users' comments about TV shows are considered a valuable indicator of the TV audience preferences. However, eliciting preferences from a tweet requires to understand if the tweet refers to a specific TV program, a task particularly challenging due to the nature of tweets - e.g., the limited length and the massive use of slangs and abbreviations. In this paper, we present a solution to identify whether a tweet posted by a user refers to one among a set of known TV programs. In such process, referred to as item detection, we assume the system is given a set of items (e.g., the TV shows or movies) together with some features (e.g., the title of the TV show). We tested the solution on a dataset composed by approximately 32000 tweets, where the optimal configuration reached a precision of about 92% with a recall equals to about 65%.

Nowadays we live in a society rich of a growing number of messages spread by multichannel and multimodal devices [9, 27, 21, 18]. A scenario that outlines the need of a designer able to manage the coexistence of multiple factors using his tools to overcome the problems of understanding information and access them. Starting from the complex nature of communication flows, we can define a main objective: to encourage a dialogue among people. For this reason, it is important to study the evolution of the existing communication systems, in order to understand the new collaborating and participative processes, and how media and languages have broken their historical isolation and incompatibility. Thanks to a large amount of theoretical assumptions, and according with thoughts and projects developed during these years [10, 13, 26, 2, 28, 5, 6],, the aim of this work is to figure out a new form of literacy that allows us to develop content able to foster a rich user experience through the merge of different languages, media, technologies, and to rethink the participatory process. First of all, the work will highlight the developments in the communication field that are affecting society, exploring three main areas: audience, technology and user engagement. After this the paper will focus on The Spiral, a pan-European Transmedia co-production, as an example of potential activities in order to do reflections on what are challenges and opportunities of the Transmedia Phenomenon within the broadcast production.

There is a growing number and variety of educational video lectures online, but there is limited understanding of their effectiveness in terms of learning and usability. Although there is significant research literature within the individual domains of usability and of video learning, there is limited understanding of their integrated design. In particular, there is limited research on guidelines for usable video lecture design, such as the presence of humans in the video and navigation support through the video. For example, it is established that learners benefit from highly structured learning material, but the manual editing of video is not feasible for most learning organizations and instructors. In order to accommodate this emerging instruction medium we are drawing design principles and models from the research literature on educational technology and video interaction. Moreover, we provide a comprehensive approach to the design of usable video lecture systems and content. Finally, we suggest that learning organizations and instructors should invest additional effort in video systems that support an integrated approach to editing, sharing, and controlling of video lectures.

The scope of user experience supersedes the concept of usability and other performance oriented measures by including for example users' emotions, motivations and a strong focus on the context of use. The purpose of this tutorial is to motivate researchers and practitioners to think about the challenging questions around how to select and apply UX evaluation methods for different usage contexts, in particular for the "home" and "mobile" context, relevant for TV-based services. Next to a general understanding of UX evaluation and available methods, we will provide concrete UX evaluation case examples and hands-on exercises. Participants will be engaged in a reflection on the practical use of methods, connected problems and challenges.

The traditional models of content delivery and creation as well as the roles of content producer and content consumer are being challenged in an environment of increasing user generated content. While the amount of user generated content is growing, there is an imbalance with respect to its quality and variety. In this paper, we discuss our research into two real collaborative documentary productions. We present two collaborative models of digital narrative content creation that demonstrate the way in which users have more control over their content and have a more immersive experience with the content. Curation of crowdsourced assets after a major natural disaster is explored in the production of "lenses + landscapes". We discuss crowdsourcing as a means to utilize existing media assets to deliver a narrative experience that consists of many small parts, but whose overall impact as a whole is greater than the sum. Co-located collaborative content creation is examined in the production of "places + perspectives". The implementation of large, remotely located touchscreens in collaborative sessions is illustrated and analyzed. By presenting the findings and details of our two experiments on collaborative storytelling, our goal is to demonstrate different methods for creating and curating collaborative content in and over remote locations to allow for a unique and enhanced user experience for content creators, collaborators and viewers.
