21、ciplinary concept. In one of form or another, the concept of the users experience or perception of the quality can be traced back to several distinct domains (human and social sciences, neuro- and cognitive sciences, marketing and business, etc., see Figure 1). These domains use their own language a

22、nd terminology and are often very compartmentalized. Diving into the specific literature of a given domain is usually not an easy task for researchers or practitioners from another domain. This fact is the main reason for the lack of common understanding and on common viewpoint of the concept of qua

23、lity as a user perceives it, and a global view of all factors influencing this perception has not been completed yet. A consequence is that, despite the growing research activities around the end-user experience, the concept of quality of experience is still an ambiguous concept that lacks a coheren

24、t theoretical basis and a commonly accepted definition. An eloquent conclusion of an ETSI workshop i.1 in 2010 was that “Quality of Experience is not a universally well understood concept“. The standardization bodies dealing with Quality of Experience are numerous (see for instance D. Soldani i.2 or

25、 A. Takahashi i.3). One of the most commonly accepted definitions for QoE is given in reference to Recommendation ITU-T P.10/G.100 3 as “the overall acceptability of an application or service, as perceived subjectively by the end-user“. This definition encompasses only implicitly all aspects of qual

26、ity of experience. It is however difficult to get enough leverage from it to find operational means allowing understanding and estimating quality of experience (QoE). 1 Scope The goal of the present document is to providthe following aspects: A clear and unambiguous terminologused to address quality
