Introduction to the QoE Workshop
In recent years, research efforts have been carried out in order to bring Quality of Service
(QoS) closer to the actual experience of the user of the service. As such, both the
normalization bodies and the academic community have worked on evolved models and
metrics to try delivering a measure of the Quality of Experience (QoE). However, QoE is an
elusive notion, since its subjective nature highly depends on human factors, which are
unfortunately often individual and complex. As QoE is a multidimensional concept,
specialists coming from heterogeneous domains such as ergonomics, behavioural
psychology, marketing, network among others, are needed to answer the following
questions: what is QoE? What is its precise area? How to measure it?
We aim at obtaining models incorporating the subjective aspects of user experience as well
as a precise definition of the different quality notions. Although ongoing work has
produced well evolved metrics for user perception on the multimedia service range, they
mainly address the quality associated to the "signal restitution" to the user more than the
actual perception in a particular usage context (content, environment, etc.). Diverse
efforts around the three main identified topics are being carried out by collaborative
projects and within academia and industry labs. We believe that an increased coordination
between the different domains might get us closer to a better understanding and modelling
of the user experience leading to improved metrics and methods.
Scope
Organized around the ITC 21 which gathers performance experts, the QoE workshop
is intended to serve as a forum to present the latest work and interests by researchers
from both academia and industry and to produce a basis for future collaboration on the
domain.
The three main subjects identified around QoE modelling and estimation are the following:


QoE Framework
o Quality Notions
o Communications ecosystem
o Interfaces, actors and roles
o Service level agreements
o etc
Service Modeling and QoE estimation
o Estimation of QoE for audio/video services
o Translating QoS to QoE
o Extending estimation methods to other services (Web, etc.)
o Human factors and their place in service models.
o etc

Subjective Test Methodologies
o State of the art on subjective test methodologies
o Defining systematic/reusable test methodologies to create economies of
scale around QoE estimation
o etc

Registration is free of charge.
Registration is open to all Euro-NF members and other invited attendants. However, as the
venue has a limited number of places, we kindly ask you to register with us
(sergio.beker@orange-ftgroup.com) so we can adequately plan logistics in advance. Also,
as the number of presentations is limited due to time constraints, we kindly ask you to:



Confirm that you will be willing to present.
Limit your presentation to current work and interests on the subject. What your
contribution would be to a collaborative proposal.
Group your presentations as much as possible by lab/institution.
Please send us an abstract of your presentation as soon as possible. We will propose a
preliminary program and agree on the final program with all registered participants. We
expect your final presentation by August 31st. Registrations will be accepted until the
day before the workshop (no on-site registration will be available). Registration
for presentations is closed.
Workshop venue
The workshop will be held at Telecom ParisTech, Paris 13, France. Telecom ParisTech is
