TVX '18

It is our great pleasure to welcome you to Seoul, Korea, for the fifth edition of the ACM International Conference on Interactive Experiences for Television and Online Video - ACM TVX 2018. We are certain that this is a great place to meet diverse research and industry communities from around the world, including those that have not previously been heavily involved in the TVX conference series. As such, we are incredibly excited to be able to present a stimulating program for ACM TVX 2018 in an equally magnificent part of the world; incidentally representing a first for this conference series - a host city in Asia!

As the leading international conference for the presentation and discussion of research and developments into interactive experiences for online video and TV, the conference brings together international researchers and practitioners from a wide range of disciplines, ranging from human-computer interaction, multimedia engineering and design to media studies, psychology and sociology, to present and discuss the latest insights in the field. The ultimate mission of the conference is to share novel ideas, concepts, and solutions that fulfill the needs of new media environments and identify new directions for future research and development.

This year's conference continues its tradition of being the premier forum in this field, following the success of the four previous editions of TVX (held in Hilversum, Chicago, Brussels and Newcastle upon Tyne), and building on the legacy of the EuroiTV conference series organized all across Europe, between 2003 and 2013. We continue to present research on topics in scope such as immersive experiences, user experiences & interaction design, content production, systems & infrastructure, devise & interaction techniques, media studies, business models & marketing, and innovative concepts & media art. In addition, we introduced two hot topics to the call for papers associated with ACM TVX 2018: AI/Big Data and Social Computing.

The call for papers attracted 36 long and short paper submissions from Asia, Europe, North & South America across both academia and industry. Being the first edition in Asia, it received new submissions from China, Japan, and Korea which were less visible in the conference series until now. All submissions went through a rigorous double-blind peer review process. Each paper was assigned a primary Associate Chair (AC) and a secondary AC. The primary AC recruited at least two reviewers for each of their assigned paper, whilst the secondary AC recruited at least one reviewer for their assigned paper. Once the reviewers submitted their evaluation of the suitability of the paper, the primary AC wrote a meta-review summarizing the main points of each review. Authors of the submissions were then notified of the completed review and given the chance to respond to the reviewers' comments during a rebuttal phase. During the TPC meeting on March 16, 2018 in Lisbon, Portugal, each paper was discussed in-depth with the ACs, and the final decision on the accepted papers was made, resulting in a high-quality program of 12 accepted full and short papers, accounting for an acceptance rate of 33%. Full papers, Short papers, the abstracts of the 2 Workshops co-located with TVX (in addition to an industry workshop close to the public), and the 17 Work In Progress papers are part of the main proceedings and will be included in the ACM Digital Library. In addition to these submissions, there were several other tracks that attracted a considerable number of contributions, resulting in 8 TVX in Industry presentations, 8 Demonstrations, 3 Doctoral Consortium papers, and 2 Grand Challenge presentations, all made available in the adjunct proceedings, along with the papers from the Wo
