ACM TVX 2017 Workshop

Announcement: First International Workshop on Converging User-Generated Material with Professional Video User Experiences

14 June 2017, Hilversum, The Netherlands

Partners from the COGNITUS project are organising a workshop at TVX2017—The ACM International Conference on Interactive experiences for Television and Online Video.  If you are actively working in this area, or just interested in finding out more, then you are all very welcome to join us.  It will be a great opportunity to discuss work happening in COGNITUS and other projects.


We invite submissions of short position papers describing research work, implementations, case studies.  Previous familiarity with the activity of the COGNITUS project is not required and we encourage wide involvement.

Position paper submissions should be in ACM Extended Abstracts format, with a maximum length of four pages plus references.  All submissions will be reviewed by the workshop’s expert programme committee.

The papers should be submitted via the EasyChair submission system.

Submission Deadline: Extended to 16 March 2017 (Closed now)


The purpose of this workshop is to bring together a diverse group of researchers and practitioners for focussed discussion and knowledge sharing.  Collectively, we will generate a research and development agenda; the research questions that we must answer and the techniques and technologies that we must invent in order to maximise the value of integrating user-generated video (UGV) with professionally-captured material.  This includes accelerating the adoption and growth of behaviours in both communities; professional producers and potential contributors.

Themes will include, but not be limited to:

  • Novel Quality of Experience (QoE) Metrics for User-Generated and Mixed-origin video

The technical capabilities of an average user’s cameraphone are increasing significantly, but there are still likely to be general differences in depth of field, video codec, lens distortion and many other features, in comparison to professional footage.  Perhaps much more significantly, there are also differences in typical shot composition and construction in video from these distinct origins.  Offsetting or reinforcing these fundamental differences are editorial factors, such as perspective and access.  How do these differences impact on a viewer’s perceived quality of experience?  What subjective metrics will we need in order to usefully distinguish between different levels of quality, and what methodologies will allow us to develop and make use of them?  Critically, what additional QoE issues may be formed by the fusion of professional and user-generated material in a single video experience, and how can we measure such percepts empirically?

  • Computational Enhancement of Perceived QoE

Following on from this, having developed the metrics for effective human assessment of video QoE, how can these be deployed in computational form in systems to maximise quality (both by supporting selection and inclusion of the most complementary material, and by enhancement in the image processing domain)?

  • Contributor Reward, Motivation and Development

In use cases within this scenario, when professional content is enhanced by inclusion of UGV, potential contributors need to be motivated to share their material with the professional broadcaster.  This motivation needs to persist, even in the very likely event that there isn’t scope for the majority of submitted video to be included in professional coverage.  What are likely motivational factors for contributors, and how do they develop with time and in different use cases?  What forms of reward, social capital and other motivational support will sustain the availability of good quality UGV to professional producers and, moreover, how can professionals support their contributors’ development to higher levels of effective creativity?

  • Methodological Research

As a novel set of behaviours, encompassing creativity, service and relationship design, and end user experience, what requirements and opportunities for new research methods may develop in this area?  For example, there are likely to be many dimensions to the human experience of personal development as a video contributor, including long-term, longitudinal considerations.  How can we develop expressive frameworks to allow these experiential factors to be captured and compared?

As an alternative example, the kind of fieldwork that is appropriate for researching the convergence of UGV with professional video will generally include relatively large-scale deployment in-the-wild.  These scenarios exhibit particular attributes, such as the inherent many-to-one structure of a professional broadcaster and a multitude of potential contributors.  This model may be sufficiently distinctive to support secondary research in developing methods that map onto such relationships.

  • Personal Data Ethics, Creative Control and Informed Choice

Scenarios in which contributors share video, perhaps including footage of other people, bring issues of consent and privacy.  Such considerations are then supplemented by questions of contributors’ and professionals’ expectations of creative control of the material.  In this developing community, what mechanisms and responsibilities do the professionals have in supporting contributors’ informed choice over what they are sharing?
