As a first step, it will be important to identify the factors strategies will be necessary to be developed and the global

good example of this approach. As referred in this
recommendation, QoE influence factors are usually Once, the standard for the “QoE factors in TEL” is defined,
grouped in three main categories (#1 to #3 in Figure 6): the next step would be the definition of the standard that
describes the “Framework for the QoE evaluation
- User influence factors methodology for TEL” (#7 to #9 in Figure 6).The
subjective model should be defined in the standard and
- Context influence factors some generalized proposals for satisfaction models found in
- System influence factors literature [45] (#7 to #9 in Figure 6) could be used.

In the first category, some key factors like the learner Figure 6 illustrates the importance of the evaluation of the
expectations, previous good or bad experiences in TEL and learner experience as an input used in the update and
the learner expertise with the subject and all the cultural enhancement of TEL systems in order to improve the
