In addition to individual user preferences, existing context-aware approaches such as tensor factorization incorporate system-level contextual bias to increase predicting accuracy. We analyzed a user interaction dataset from a WebTV platform, and identified that such contextual bias creates a skewed selection of recommended programs which ultimately locks users in a filter bubble. To address this issue, we introduce the Twitter social stream as a source of external context to extend the choice with items related to social media events. We apply two trend indicators, Trend Momentum and SigniScore, to the Twitter histories of relevant programs. The evaluation reveals that Trend Momentum outperforms SigniScore and signalizes 96% of all peaks ahead of time regarding the selected candidate program titles.","PeriodicalId":314992,"journal":{"name":"Proceedings of the 2017 ACM International Conference on Interactive Experiences for TV and Online Video","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122386920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the challenging aspects we will focus on is the growing user requirement for real-time mobile information and stories anytime and anywhere. This has exerted significant pressure on the importance of new forms of storytelling and information delivery on every target audiences. We will examine how to adopt new forms of digital storytelling in traditional media such as TV broadcasting. The workshop will stimulate discussions and experiences among a broad spectrum of workshop participants, such as researchers, industry, designers, and artists on how to create stories and journalism that think about information delivery in real time. The first part of this workshop consists of presentations submitted to this workshop. Here, potential effects of using digital storytelling in creation and participation of media will be discussed. Furthermore, we will also have presentations on use cases, artistic research and demonstrations of design and storytelling. To foster creativity and discussions among participants, presentations are followed by interactive group-work. Here, participants have the chance to express their ideas and scenarios on how to effectively include audiences' opinion into TV broadcasting. The workshop will be concluded by a panel discussion on the topic of new storytelling perspectives in broadcasting, and will cover aspects of the group-work and presentation of submitted work to the workshop.","PeriodicalId":314992,"journal":{"name":"Proceedings of the 2017 ACM International Conference on Interactive Experiences for TV and Online Video","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124533247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work is motivated by an increasing number of sensors (such as Kinect) that find their way into living rooms. Such sensors allow the behavior of viewers to be analyzed, hence providing the opportunity to instantly react to this behavior. The particular idea we explore in our work is how a second screen app triggered by the viewer's behavior can be designed to make them re-engage with the TV content. At the outset of our work we conducted a survey (N=411) to assess viewers' activities while watching TV. Based on the findings we implemented a Kinect-based system to detect these activities and connected it with a playful second screen app. We then conducted a field evaluation (N=20) where we compared (a) four hints to direct users' attention to the second screen app and (b) four types of second screen content requiring different levels of engagement.

Through the use of a synchronised, interactive textbook application, we conducted a user study to evaluate the potential influence of different delays, between the TV and the companion screen, on how users experience watching a Shakespearean play on the TV. Our results indicate that although users do not notice delays of up to 1000 ms, for the kind of experience tested, they feel significantly more distracted by the tablet content for increasingly higher delays. We discuss the implications of our findings with regards to the time delay tolerances users might have when using a synchronised text accompaniment to these kinds of TV programmes.","PeriodicalId":314992,"journal":{"name":"Proceedings of the 2017 ACM International Conference on Interactive Experiences for TV and Online Video","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131621426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent years have also seen proposals for the development of home systems that could ultimately approximate CAVE-like experiences. The question arises as to the nature of the user experience of viewing panoramic video in head mounted displays compared to CAVE-like systems. User preference seems hard to predict. Accordingly, this study took a qualitative approach to describing user experience of viewing a panoramic video on both platforms, using a thematic analysis. Sixteen users tried both viewing conditions and equal numbers expressed preferences for each display system. The differences in user experience by viewing condition are discussed in detail via themes emerging from the analysis.","PeriodicalId":314992,"journal":{"name":"Proceedings of the 2017 ACM International Conference on Interactive Experiences for TV and Online Video","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124363809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
