Multimedia and audio-visual services are observing a huge explosion during the last years. In this context, users' satisfaction is the aim of each service provider to reduce the churn, promote new services and improve the ARPU (Average Revenue per User). Consequently, Quality of experience (QoE) consideration becomes crucial for evaluating the users' perceived quality for the provided services and hence reflects the users' satisfaction. QoE is a multidimensional concept consisting of both objective and subjective aspects. For adequate QoE measure, the context information on the network, devices, the user and his localization have to be considered for successful estimation of the user's experience. Up till now, QoE is a young subject with few consideration of context information. This paper presents a new notion of user's experience through introducing contextawareness to the QoE notion. A detailed overview and comparison of the classical QoE measurement techniques are given. The literature contributions for QoE measurement are also presented and analyzed according to the new notion of user's experience given in this paper.
