    Attention Guidance in Second Screen Applications
    (Mensch und Computer 2019 - Tagungsband, 2019) Lohmüller, Valentin; Eiermann, Philip; Zeitlhöfler, Peter; Wolff, Christian
    The use of a secondary device alongside a first screen, such as a television, is referred to as second screening and is generally considered as a common and widespread behavior. With the advent of smart first screens (smart TVs, set-top boxes, streaming sticks, etc.), this type of activity gained a new perspective in the form of connected second screen applications such as YouTube, Netflix, or Amazon Prime Video which enable functionalities such as the dis-play of additional information or remote control aspects on the second screen. The design of these distributed applications is difficult because the user´s attention cannot be focused on both parts at the same time, which is why this paper presents two eye-tracking studies investigating this problem. The studies examined on the one hand the general viewing behavior with second screen applications and on the other hand the targeted directing of attention to the first and second screens. From these results, recommendations for the design of second screen applications are derived and presented, with the aim that the two application parts complement each other rather than competing for the user's attention.

    Towards a Comprehensive Definition of Second Screen
    (Mensch und Computer 2019 - Tagungsband, 2019) Lohmüller, Valentin; Wolff, Christian
    Second screening is a widespread activity among users, although many are not aware of the term, and second screen applications are becoming increasingly popular in research and commercial use, from well-known examples such as Netflix, Amazon Prime Video or YouTube to applications that enable novel uses cases and have the potential to change the current usage behavior of the content on the first screen. Despite the increasing prevalence of this phenomenon, there are different interpretations in the relevant literature and in existing applications about what exactly is meant by the term second screen. In order to evaluate these different interpretations, we conducted a structured review of literature (SRL) on 65 publications in this area and reflected the results on an analysis of currently available second screen applications to precisely delineate the term and its characteristics. Furthermore, we derived a content and technical classification that will make it easier to manage the various benefits and characteristics of second screen applications in the future, to create a framework for the appropriate positioning of new research activities and reasoned basis for discussion.

    UCAI 2020: Workshop on User-Centered Artificial Intelligence
    (Mensch und Computer 2020 - Workshopband, 2020) Augstein, Mirjam; Buschek, Daniel; Herder, Eelco; Loepp, Benedikt; Yigitbas, Enes; Ziegler, Jürgen
    The proliferation of AI-based techniques poses a range of new challenges for the design and engineering of interactive and adaptive systems since they tend to act as black boxes and do not offer the user sufficient transparency, control, and interaction opportunities, which are considered major goals of user-centered design in the HCI field. This workshop aims at sharing and discussing recent developments at the intersection of HCI and AI, and at exploring novel methodological, technical, and interaction approaches. Researchers with diverse disciplinary backgrounds will contribute to advancing the research agenda in this emerging field of research.
