Understanding user experience of mobile video: Framework, measurement, and optimization

Since users have become the focus of product/service design in last decade, the term User eXperience (UX) has been frequently used in the field of Human-Computer-Interaction (HCI). Research on UX facilitates a better understanding of the various aspects of the user’s interaction with the product or service. Mobile video, as a new and promising service and research field, has attracted great attention. Due to the significance of UX in the success of mobile video (Jordan, 2002), many researchers have centered on this area, examining users’ expectations, motivations, requirements, and usage context. As a result, many influencing factors have been explored (Buchinger, Kriglstein, Brandt & Hlavacs, 2011; Buchinger, Kriglstein & Hlavacs, 2009). However, a general framework for specific mobile video service is lacking for structuring such a great number of factors. To measure user experience of multimedia services such as mobile video, quality of experience (QoE) has recently become a prominent concept. In contrast to the traditionally used concept quality of service (QoS), QoE not only involves objectively measuring the delivered service but also takes into account user’s needs and desires when using the service, emphasizing the user’s overall acceptability on the service. Many QoE metrics are able to estimate the user perceived quality or acceptability of mobile video, but may be not enough accurate for the overall UX prediction due to the complexity of UX. Only a few frameworks of QoE have addressed more aspects of UX for mobile multimedia applications but need be transformed into practical measures. The challenge of optimizing UX remains adaptations to the resource constrains (e.g., network conditions, mobile device capabilities, and heterogeneous usage contexts) as well as meeting complicated user requirements (e.g., usage purposes and personal preferences). In this chapter, we investigate the existing important UX frameworks, compare their similarities and discuss some important features that fit in the mobile video service. Based on the previous research, we propose a simple UX framework for mobile video application by mapping a variety of influencing factors of UX upon a typical mobile video delivery system. Each component and its factors are explored with comprehensive literature reviews. The proposed framework may benefit in user-centred design of mobile video through taking a complete consideration of UX influences and in improvement of mobile videoservice quality by adjusting the values of certain factors to produce a positive user experience. It may also facilitate relative research in the way of locating important issues to study, clarifying research scopes, and setting up proper study procedures. We then review a great deal of research on UX measurement, including QoE metrics and QoE frameworks of mobile multimedia. Finally, we discuss how to achieve an optimal quality of user experience by focusing on the issues of various aspects of UX of mobile video. In the conclusion, we suggest some open issues for future study

Crossovers: Digitalization and literature in foreign language education

Digitalization produces increasingly multimodal and interactive literary forms. A major challenge for foreign language education in adopting such forms lies in deconstructing discursive borders between literary education and digital education (romance of the book vs. euphoric media heavens), thereby crossing over into a perspective in which digital and literary education are intertwined. In engaging with digital literary texts, it is additionally important to consider how different competencies and literary/literacy practices interact and inform each other, including: (1) a receptive perspective: reading digital narratives and digital literature can become a space for literary aesthetic experience, and (2) a productive perspective: learners can become “produsers” (Bruns, 2008) of their own digital narratives by drawing on existing genre conventions and redesigning “available designs” (New London Group, 1996). Consequently, we propose a typology of digital literatures, incorporating functional, interactive and narrative aspects, as applied to a diverse range of digital texts. To further support our discussion, we draw on a range of international studies in the fields of literacies education and 21st century literatures (e.g., Beavis, 2010; Hammond, 2016; Kalantzis & Cope, 2012; Ryan, 2015) and, in turn, explore trajectories for using concrete digital literary texts in the foreign language classroom

How Dental Hygiene Undergraduate Learning is Influenced by Educational Videos

How Dental Hygiene Undergraduate Learning is Influenced by Educational Videos Abstract This pilot experimental research study evaluated the efficacy of educational videos in comparison to traditional learning with print media and evaluated the student’s knowledge and retention of utilizing the periodontal screening and recording (PSR) method. The sample size consisted of 23 undergraduate students enrolled in their second year in a baccalaureate dental hygiene program. Participants were placed into two randomized groups, labeled Group A consisting of 12 students and Group B consisting of 11 students and evaluated with a 10 question pre test before exposure to the educational intervention, followed by a 10 question post test. Group A, n = 12, was exposed to a 5 minute educational video and the results showed a mean score difference of 0.467, df = 11, SD = 0.137, SEM (standard error of difference) = 0.040. Group B, n = 11, was exposed to traditional print media and the results showed a mean score difference of 0.473, df = 10, SD = 0.119, SEM = 0.036. By conventional criteria, the difference between the two groups is considered to be not statistically significant. When comparing the results of the group exposed to the educational video to the group that learned via traditional print media, the lack of statistical difference in the student’s results indicates that the educational videos are just as effective as the print media when used as a learning tool. Future studies could provide a more thorough investigation including a larger sample size with various levels of students to help determine if the educational video method utilized in this pilot study shows a statistical improvement in student learning over traditional print media methods

Youth and Digital Media: From Credibility to Information Quality

Building upon a process-and context-oriented information quality framework, this paper seeks to map and explore what we know about the ways in which young users of age 18 and under search for information online, how they evaluate information, and how their related practices of content creation, levels of new literacies, general digital media usage, and social patterns affect these activities. A review of selected literature at the intersection of digital media, youth, and information quality -- primarily works from library and information science, sociology, education, and selected ethnographic studies -- reveals patterns in youth's information-seeking behavior, but also highlights the importance of contextual and demographic factors both for search and evaluation. Looking at the phenomenon from an information-learning and educational perspective, the literature shows that youth develop competencies for personal goals that sometimes do not transfer to school, and are sometimes not appropriate for school. Thus far, educational initiatives to educate youth about search, evaluation, or creation have depended greatly on the local circumstances for their success or failure

Proceedings of the International Workshop on EuroPLOT Persuasive Technology for Learning, Education and Teaching (IWEPLET 2013)

"This book contains the proceedings of the International Workshop on EuroPLOT Persuasive Technology for Learning, Education and Teaching (IWEPLET) 2013 which was held on 16.-17.September 2013 in Paphos (Cyprus) in conjunction with the EC-TEL conference. The workshop and hence the proceedings are divided in two parts: on Day 1 the EuroPLOT project and its results are introduced, with papers about the specific case studies and their evaluation. On Day 2, peer-reviewed papers are presented which address specific topics and issues going beyond the EuroPLOT scope. This workshop is one of the deliverables (D 2.6) of the EuroPLOT project, which has been funded from November 2010 – October 2013 by the Education, Audiovisual and Culture Executive Agency (EACEA) of the European Commission through the Lifelong Learning Programme (LLL) by grant #511633. The purpose of this project was to develop and evaluate Persuasive Learning Objects and Technologies (PLOTS), based on ideas of BJ Fogg. The purpose of this workshop is to summarize the findings obtained during this project and disseminate them to an interested audience. Furthermore, it shall foster discussions about the future of persuasive technology and design in the context of learning, education and teaching. The international community working in this area of research is relatively small. Nevertheless, we have received a number of high-quality submissions which went through a peer-review process before being selected for presentation and publication. We hope that the information found in this book is useful to the reader and that more interest in this novel approach of persuasive design for teaching/education/learning is stimulated. We are very grateful to the organisers of EC-TEL 2013 for allowing to host IWEPLET 2013 within their organisational facilities which helped us a lot in preparing this event. I am also very grateful to everyone in the EuroPLOT team for collaborating so effectively in these three years towards creating excellent outputs, and for being such a nice group with a very positive spirit also beyond work. And finally I would like to thank the EACEA for providing the financial resources for the EuroPLOT project and for being very helpful when needed. This funding made it possible to organise the IWEPLET workshop without charging a fee from the participants.

Immersive Storytelling in 360-Degree Videos: An Analysis of Interplay Between Narrative and Technical Immersion

Three-hundred-and-sixty-degree videos are an innovative video format, and due to various narrative and technical aspects, they allow audiences to be deeply immersed in their content. Through an explorative, qualitative content analysis (and parts of narrative analysis) aspects of immersion were explored in various 360-degree videos. Our results give an overview of multiple immersive factors in 360-degree storytelling and the interplay of narrative and technical aspects of immersion. Technical immersion manifests through cues to direct the viewer’s attention and cues to acknowledge the viewer as a part of the virtual environment. Narrative immersion, on the other hand, is influenced by the setting, as well as by the interplay of story, characters, and viewer integration. Our findings also indicate that narrative and technical aspects support each other to strengthen immersion
