Welcome from the General Chairs

At IIT Institute of Design (ID), we are excited to bring the International Conference on Interactive TV and Online Video (ACM TVX2016) to Chicago, USA. We love this opportunity to connect the great academic and industry institutions of our region with world-class researchers in multi-disciplinary aspects of Interactive Media Systems. In this era of curved televisions, large screen smartphones, the Internet of Things, and data in “the cloud,” there are many new opportunities for interactions and immersion in rich media and social life around it. The iTV research community has conducted rigorous inquiries into the roles of various disciplines including design, psychology, sociology, and technology to create iTV and online video systems that support meaningful engagement and immersion in media.

IIT Institute of Design’s (ID’s) role as a pioneer is to constantly usher in new opportunities. Our school has been an advocate in the development and dissemination of modern design right from its founding in 1937 as the New Bauhaus. In the 1960s, ID became a center of the first design methods movement — among the first applications of computers to design. In the 1990s, ID helped pioneer the human-centered approach to design. In the 2000s, ID helped launch the design thinking movement, linking design more closely to business innovation. Our school has a long history in Photography, and Design of rich media experiences for people.

This conference would not be possible without the financial support from different supporters. First of all, we would like to thank you for registering and attending the conference, as you are an important part of our community. We would also like to thank all members of the organizing committee, program committee and the steering committee. Finally, we want to thank our sponsors, ACM SIGCHI, ACM SIGWEB and ACM SIGMM and our generous corporate supporter SAMSUNG who provided the much welcomed support for making this conference an enjoyable experience. Additionally we also would like to thank our associate event presenters: Proto.io, Luso-American Foundation and FX PAL.

We wish you have a great conference and hope that you will enjoy your stay in Chicago!

Welcome from the Program Chairs

We are very pleased to present an exciting program for ACM TVX 2016, which has been put together based on many submissions from all over the world. As the leading international conference for presentation and discussion of research into interactive media experiences, we hope to present and discuss the latest insights in the field.

The call for papers attracted submissions from Asia, Europe, and the United States. Thirty eight full and short papers were submitted and subjected to a thorough double-blind review process. During the Program Committee meeting on March 21 - 22, 2016, in Chicago, IL, USA, each paper was discussed in depth and the final decision of which papers to accept was made, resulting in a high-quality program of 12 accepted full and short papers and an acceptance rate of 33%. Work in Progress papers were also reviewed by at least 2 reviewers per paper, of which 8 were accepted and will be presented as a poster during the conference. Full papers, short papers and Works in Progress are part of the main proceedings and will be included in the ACM Digital Library.

In addition to these submissions, there were several other categories that received submissions, resulting in 4 workshops, 3 courses, 5 Doctoral Consortium papers, 6 TVX in Industry presentations, and 6 demos, which are all made available in the adjunct proceedings.

Finally, we also encourage attendees to attend the keynote: “We are the [virtual] 99%”: Bringing the promise of Live Digital Interaction to all the Peoples, presented by Tawny Schlieski of Intel Corporation.

Program of ACM TVX2016 was a team effort. We would therefore like to thank the authors for their submissions, the reviewers for reviewing papers and providing feedback for authors, and the ACs who managed the whole review process for each paper. We hope that you will find this program interesting and thought-provoking and that the conference will provide you with a valuable opportunity to share ideas with other researchers and practitioners from institutions around the world.

COURSEACM TVX 2016 offers a course designed to appeal to our audience of researchers and practitioners in the TV User Experience field. Courses will take place on June 22nd 2016, the day prior to the main ACM TVX2016 conference program. The duration is half a day.

COURSE: INTERACTIVE TELEVISION EXPERIENCE IN CONVERGENT ENVIRONMENT: MODELS, RECEPTION AND BUSINESS

Valdecir Becker Informatics Centre, Federal University of Paraíba, João Pessoa, Paraíba, Brazil Contact: valdecir@ci.ufpb.br

Overview/Abstract: This course will discuss the interactivity on television, which has evolved considerably in recent years. After the walled garden model, widely discussed in this congress some year ago, models based on applications and connected TVs are emerging, with two consequences: effective participation of viewers in programming, especially live, and deprogramming schedule in pay TV systems. Planning the content for this scenario happens to be the biggest challenge of the current television. Finally, the course will explore possible paths for the future of interactivity, such as immersion in videos through spatial and temporal zoom with synchronization of things.

Summary: WSICC has established itself as a truly interactive workshop at EuroITV’13, TVX’14, and TVX’15 with three successful editions. The fourth edition of the WSICC workshop aims to bring together researchers and practitioners working on novel approaches for interactive multimedia content consumption. New technologies, devices, media formats, and consumption paradigms are emerging that allow for new types of interactivity. Examples include multi-panoramic video and object-based audio, increasingly available in live scenarios with content feeds from a multitude of sources.

All these recent advances have an impact on different aspects related to interactive content consumption, which the workshop categorizes into Enabling Technologies, Content, User Experience, and User Interaction. The resources from past editions of the workshop are available on the http://wsicc.net website.

Summary: Many theories and models have been generated from the fields of informatics, medicine, psychology, and sociology on the topic of persuasion to describe aspects of human behavior, human/computer interaction, and information systems involved in supporting behavior change. But, what specific methods should we select to design specific user experiences, especially for iTV experiences? In this workshop, we will seek and share perspectives on how to create user experiences for iTV and other media by building on BJ Fogg’s initial description of a general user research and design method [1], draw from Harri Oinas-Kukkonen’s Persuasive Systems Design model [2], and explore pragmatic approaches for creating user experiences design knowledge for aspects of iTV and Online Media.

DESIGN STRATEGIES FOR INTERACTIVE DIGITAL NARRATIVES

Organising team:Hartmut Koenitz , Entertainment and Media Studies, University of Georgia

Summary: Creating interactive digital narrative (IDN) experiences means to overcome a tradition dominated by conventions for non-interactive, static and pre-fixed narrative. Instead of “interactivizing” legacy structures, a more productive avenue is in the focus on specific design strategies for IDN. These approaches do afford a a different view towards the resulting manifestations – both form and context –, but also include a perspective on the changed role of the author.

OPENING KEYNOTE

We are approaching the dawn of a communications revolution, where interactive digital information enables entertainment, education, and industry in ways that we have only imagined in science fiction. Investors have dropped more than a billion dollars into the industry in the first two months of 2016. The first wave of interface technologies are beginning to reach developers. And a handful of new experiences are making their way to consumers. So who benefits from this revolution? VR and AR are not technologies relevant only the tech elite. This is a shift in how we communicate with computers and digital information that will give voice to many people, and empower companies and entrepreneurs from many disciplines to create a future, rich with opportunity.

Abstract: Live streaming has recently emerged as a growing form of participatory social media. While current live streaming practice focuses on single stream experiences, there are increasing instances of events covered by multiple live streams. In order to explore how to support communication and participation in multi-stream experiences, we present the design and evaluation of Rivulet, an end-to-end mobile live streaming system designed to support participatory multi-stream experiences. Rivulet affords simultaneously watch-ing multiple live streams and incorporates existing feedback mechanisms of text chat and hearts with a novel push-to-talk audio modality. By recruiting viewers through Mechanical Turk, we were able to conduct a study of Rivulet at scale. We found that Rivulet afforded new engaging experiences for participants and led to an impromptu sense of community.

John Tang, Microsoft Research Gina Venolia, Microsoft Research Kori Inkpen, Microsoft ResearchAbstract: Live events are happening all around the world all the time. People are using mobile livestreaming tools (Periscope, Facebook Live, Livestream, etc.) to broadcast those events over video and audio. How can we connect viewers with livestreams of events in which they are interested? How can we help viewers leverage multiple livestreams com-ing from an event to find the perspective they find interesting? How can we create a user experience that enables them to participate in the event remotely, not just passively watch it? We explored these ideas using commercially available apps and services to eventstream the Silicon Valley Comic Con.

Marc Aguilar , Sergi Fernández, David Cassanyi2CAT Foundation, Barcelona, SpainAbstract: This paper describes the results of a large-scale live pilot test of an HbbTV multicamera application. In this pilot test, carried out during an association football match, the interactions of 6203 user devices with the application were logged. An exploratory statistical analysis was performed on the dataset, to better understand the behavior of the users on the application. The analysis yielded conclusions that can be useful to those seeking to build a successful multicamera service, with insights on issues of suitability of program genres, multi-camera content selection, audience segmentation, and the structure of data stream traffic.

Abstract: Consumer live video communication has now become an established communication medium, but the current systems are still quite limited in their ability to support natural communication in more complex interaction setups. What new features might be required to further expand live video communication? This paper suggests: “orchestration” – i.e. the ability to automatically and in real-time (re)configure the communication system to the needs of the interaction context. The inspiration for communication orchestration is television production through mixing views from different cameras and camera reframing. This paper reports a specific study of orchestration carried out in the social setting of a group of friends communicating from three separate living rooms through television screens and multiple cameras. The orchestrated experience was evaluated against a static (split screen) connection, and was carried out via a questionnaire, analysis of automatic logs and interviews. In this case study, orchestration has been identified as providing for more intimate conversations, whereas, the static solution emerged to be better for conveying group awareness.

Dimph de Feijter, NHTV Breda University of Applied SciencesVassilis-Javed Khan, Eindhoven University of TechnologyMarnix van Gisbergen, NHTV Breda University of Applied SciencesAbstract: Viewers more frequently watch television content whenever they want, using devices they prefer, which stimulated ‘Binge-watching’ (consecutive viewing of television programs). An in-situ, smartphone monitoring survey among Dutch binge-watchers was used to reveal context factors related to binge-watching and wellbeing. Results indicate that binge-watching is a solitary activity that occurs in an online socially active context. The amount of time spent binge-watching (number of episodes) correlates with the amount of free time and plays an important role in the effect of binge-watching on emotional wellbeing. Considering the difficulty viewers have to create an optimal view-ing experience, these context factors are used as a framework to be able to design and promote a recommendation tool for TV streaming services to create a more optimal binge-watching experience.

Frank Bentley , Yahoo, Sunnyvale, California, United States Janet Murray , Georgia Tech, Atlanta, GA, USAAbstract: New video platforms have enabled a wide variety of opportunities for rewatching video content. From streaming sites such as Netflix, Hulu, and HBO Now, to the proliferation of syndicated content on cable and satellite television, to new streaming devices for the home such as Roku and Apple TV, there are countless ways that people can rewatch movies and television shows. But what are people doing? We set out to understand current rewatching practices across a variety of devices and services. Through an online, open-ended survey to 150 diverse people and in- depth, in-person interviews with 10 participants, we explore current rewatching behaviors. We quantify the types of content that are being rewatched as well as qualitatively explore the reasons and contexts behind rewatching. We conclude with key implications for the design of new video systems to promote rewatching behaviors.

Maria Cipollone, Jennifer Ackerman, Elizabeth KellComcast User Experience ResearchAbstract: MDigital video on-demand (VOD) content libraries offer users deep and wide-ranging choices about what they should watch on television. However, the search and discover mechanism of digital video on demand services support a more information seeking interaction than relaxed yet serendipitous and time-sensitive discovery. In subsequent studies, users tell us that it’s less rewarding and social. In this paper, we share lessons learned across multiple studies: that users delight in the serendipity and low-commitment associated with linear browsing, particularly in the interactive guide. We suggest that future recommender systems consider the delightful serendipity of huntingfor something to watch on television as a hedonic experience. We also question whether growing digital content libraries will render this behavior obsolete—or whether a new user experience will cause it to evolve beyond the current experience.

Allie Johns, Adam Galpin, Joanne MeredithPsychology, University of Salford, Salford, UKMaxine Glancy , Research & Development, BBC, UKAbstract: This paper reports results from a study which examined viewers’ cognitive and affective responses to an interactive TV drama. Ten participants were videoed interacting with ‘Our World War’ [1], and then interviewed about their experience using the video playback as a retrospective prompt. An interpretative framework was designed to guide analysis by probing themes of narrative engagement identified in previous literature. We report findings relating to five themes of engagement: cognitive, affective, perspective taking, competence and autonomy, and transportation. Our data adds to the existing literature on interactive stories by highlighting the pivotal role of the self in engaging with interactive drama, with self-reflection emerging within each theme. We conclude that two experiential states drive engagement: a transported experience; and one in which self-re-flection limits transportation.

Vinoba Vinayagamoorthy, Rajiv Ramdhany and Matt HammondBritish Broadcasting CorporationLondon, Greater London, UKAbstract: This paper describes the development and implementation of an open communication standard between Internet-connected TVs and companion screens, over the home network. Content providers know that the better Internet connectivity and prevalence of personal mobile devices is encouraging our audiences to seek more interactive experiences across multiple screens. In order to deliver a coherent integrated user experience, with content on all screens presented according to a common timeline, the application on the companion device needs to discover what is being shown on the TV and what the timeline position is. DVB-CSS provides a standardised way to enable this synchronisation between the TV and any personal device on the home network. We describe its development, use cases and early prototype implementation.

Abstract: This paper addresses the question: are smartphone TV apps as easy to use as remote controls for controlling TV. Although smartphone apps make it easier to navigate lists of items, such as TV shows, access to other often-used functions may be less efficient because assess requires extra navigation. Also, additional steps required to access the TV app on the smartphone may offset any inherent advantage to using it. Smartphone app designs could reduce or eliminate this extra navigation and make smartphone TV apps more efficient and thus preferred over remote controls.

Johannes Knittel , University of Stuttgart, Stuttgart, Germany Tilman Dingler , VIS, University of Stuttgart, Stuttgart, GermanyAbstract: In this paper we present an approach for automatically extracting keywords from subtitles in order to retrieve and provide highly relevant additional program content. Our system includes a second-screen app which proactively displays these contents with hindsight to time and position in the current TV show. We then conducted a user study with 30 participants investigating the relationship between app usage while watching documentaries and effects on comprehension, recall, and subjective experience. We confirmed user distraction while using the app, but noticed an increase in subjectively reported comprehension compared to when users triggered web-searches via a smartphone browser.

To achieve this goal, our group envisioned a product called GameBridge, which builds upon the concept of transmedia storytelling by imple-menting a cross-platform narrative. For our prototype, we decided to take the television show Game of Thrones and the corresponding book series, A Song of Ice and Fire, to create a game using content from both media to form our own storyline. By using both the television show and the book series, GameBridge creates a convergence point between the two media and allows the interactor to have agency of the story through gameplay.

UNCOVERING THE UNDERLYING FACTORS OF SMART TV UX OVER TIME: A MULTI-STUDY, MIXED-METHOD APPROACH

Jincheul Jang , Dapeng Zhao , Woneui Hong , Youkyoung Park, and Mun Yi. KAIST, Republic of KoreaAbstract: The objective of this research is to explore and identify Smart TV user experience (UX) factors over different time periods employing multiple methods so as to overcome the weakness of a single study approach. To identify the effect of contextual dimensions on the Smart TV UX, we conducted empirical studies exploiting different methods of think-aloud and diary method under two usage conditions: laboratory and real-life in the participants’ residence. The factors identified through each study were integrated into a single set and further refined through peer review resulting in a final set of 19 UX factors. Metrics for these 19 UX factors were generated and used in an online survey, in which over 300 Smart TV users participated. The empirical evidences from each study suggest that the UX factors vary with respect to product temporality. The findings indicate practical implications for Smart TV manufacturers, marketing managers, application developers, and service providers.

Abstract: Notifications are among the core mechanisms of most smart devices. Smartphones, smartwatches, tablets and smart glasses all provide similar means to notify the user. For smart TVs, however, no standard notification mechanism has been established. Smart TVs are unlike other smart devices because they are used by multiple people - often at the same time. It is unclear how notifications on smart TVs should be designed and which information users need. From a set of focus groups, we derive a design space for notifications on smart TVs. By further studying selected design alternatives in an online survey and lab study we show, for example, that users demand different information when they are watching TV with others and that privacy is a major concern. We derive according design guidelines for notifications on smart TVs that developers can use to gain the user’s attention in a meaningful way.

Abstract: In this talk we explore what these future projections might actually look like for consumers, what kinds of challenges these present, and how we might start to design for an ideal user experience as we reach for the future. We also discuss projections our team made years ago about the future of home entertainment: what we got right and what we are still working on.

Katrin Plaumann, David Lehr, Enrico RukzioUlm University, Ulm, Germany Abstract: In recent years, mid-air gestures have become a feasible input modality for controlling and manipulating digital content. In case of controlling TVs, mid-air gestures eliminate the need to hold remote controls, which quite often are not at hand or even need to be searched before use. Thus, mid-air gestures quicken interactions. In this paper, we propose an interaction technique solving the conflicts arising in such multi viewer scenarios. We conducted a survey with 64 participants, asking them about their TV viewing habits, experienced conflicts and opinions on conflict solving strategies. Based on the survey’s results, we present a prototype for multi viewer gestural controls for TVs which solves possible conflicts.

Abstract: Creating an application framework is no small undertaking. You are creating the patterns, controls and design principles that others will use to create a multitude of applications. This takes on a particular importance when the platform is interactive TV. Unlike desktop computers and mobile apps there are fewer interaction conventions for television UI. Often interactive TV borrows approaches from desktop UI which don’t always translate well to a form factor with limited processing power and input constraints.
