Guest Editorial: Interactive Media: Technology and Experience
The shifting balance between lean-back passive TV/Web-based media experience and lean-forward interactivity has led to new forms of collaborative content creation. This allows controlling media with a companion screen and more advanced forms of audiovisual content interaction. Based on such developments, new media formats and consumption paradigms that allow for new types of interactivity have emerged.
“Interactive Video Search Tools: A Detailed Analysis of the Video Browser Showdown 2015” (10.1007/s11042-016-3661-2) by Claudiu Cobârzan, Klaus Schöffmann, Werner Bailer, Wolfgang Hürst, Adam Blažek, Jakub Lokoč, Stefanos Vrochidis, Kai Uwe Barthel, and Luca Rossetto. Current research tries to identify the best combinations of image, audio, and text features that combined with innovative UI design maximize interactive video retrieval tools performance. The 2015 edition of the Video Browser Showdown including its setup and the participating tools is described. The performance of those tools is presented and analyzed, interesting highlights are marked.
“Co-Present and Remote Audience Experiences: Intensity and Cohesion” (10.1007/s11042-016-3879-z) by Erik Geelhoed, Kuldip Singh-Barmi, Ian Biscoe, Pablo Cesar, Jack Jansen, Chen Wang, and Rene Kaiser. This article presents the results of modelling audience response to new types of networked theatre plays introducing two types of metrics: Intensity relates to how intensively co-present and remote aspects of a performance are rated. Cohesion relates to how a performance as a whole (copresent and remote aspects) affects an audience. Furthermore, an innovative way of bundling relevant emerging technologies is needed to give a voice to the, as yet silent, remote audience.
“Personalized Presentation Annotations Using Optical HMDs“(10.1007/s11042-016-4064-0) by Wyko Rijnsburger and Sven Kratz. It is difficult to adjust the content of traditional slide presentations to the knowledge level, interest, and role of individuals. This article presents a prototype eliminating non-pertinent information from slides by presenting annotations for individual attendees on optical head-mounted displays. Results show that annotations with a limited amount of information can significantly increase the amount of knowledge gained from attending a group presentation leading to a more clear and joyful experience.
“Video Processing for Panoramic Streaming Using HVEC and its Scalable Extensions” (10.1007/s11042-016-4097-4) by Yago Sanchez de la Fuente, Robert Skupin, and Thomas Schierl. Special transport schemes for panoramic video delivery allow users to navigate interactively within high-resolution videos using Regions-of-Interest (RoI). The solution proposed within this article is built upon tile-based panoramic streaming and provides a low-complexity compressed domain video processing technique for using H.265/HEVC and its scalable extensions. The proposed technique overcomes the scalability issue of previous solutions not using tiles and battery consumption issues while reducing peak streaming bitrate during changes of the RoI.
“Social Experiences within the Home Using Second Screen TV Applications” (10.1007/s11042-016-3646-1) by Jeroen Vanattenhoven and David Geerts. This article presents studies about social interaction between collocated viewers using second screen devices while watching TV, using applications that were designed for a specific TV program. Based on the findings of the user studies guidelines are formulated for the design of social second screen applications.
“Extending Multimedia Languages to Support Multimodal User Interactions” (10.1007/s11042-016-3846-8) by Álan Livio Vasconcelos Guedes, Roberto Gerson de Albuquerque Azevedo, and Simone Diniz Junqueira Barbosa. Aiming to assist the development of multimedia applications with multimodal user interfaces, the integration of concepts from those two communities in a unique high-level programming framework is proposed. The framework is instantiated and evaluated in the NCL (Nested Context Language) multimedia language.
“WanderCouch - A Smart TV Approach Towards Experiencing Music Festivals Live from the Living Room” (10.1007/s11042-016-3888-y) by Maarten Wijnants, Gustavo Rovelo, Peter Quax, and Wim Lamotte. This article reports on user expectations of immersively experiencing music festivals. Out of these expectations, an approach for remote festival engagement blending professional and user-generated content is distilled. The approach is implemented into a Smart TV application called WanderCouch and evaluated in a simulated live setting.
“Academic Methods for Usability Evaluation of Serious Games: A Systematic Review” (10.1007/s11042-016-3845-9) by Rosa Yáñez-Gómez, Daniel Cascado-Caballero, and José-Luis Sevillano. In the last years, there has been an increasing interest in the design of video games. Usability as a key factor becomes even more important in “serious games”, where the users’ special characteristics should be considered, and the game efficacy depends on the users' adherence and engagement. This systematic review illustrates the general status of current academic usability evaluations of these games. It describes the main trends in the selection of methodologies and how they are applied.
