A Generic Utility Model Representing th...

The Quality of Experience (QoE) can be defined as "the degree of delight or annoyance of the user of an application or service. It results from the fulfillment of his or her expectations with respect to the utility and / or enjoyment of the application or service in the light of the users' personality and current state" [Le Callet et al. 2012].

However, different application domains may have different requirements in terms of QoE. Thus, there is a need to provide specializations of such a generally agreed definition of QoE pertaining to the respective application domain taking into account its requirements formulated by means of influence factors and features of QoE (cf. Sections 5 and 6 of [Le Callet et al. 2012]). Consequently, an application-specific QoE definition is provided by selecting the influence factors and features of QoE reflecting the requirements of the application domain and incorporating them into the generally agreed definition of QoE.
