Abstract: The rapid development of multimedia services has attracted increasing attention on the interests in the study of quality of experience (QoE) in the multimedia domain. QoE, as a promising user-centric quality evaluation metric, has gradually been a hot research topic in recent years. Compared with conventional multimedia service quality metrics [e.g., quality of service (QoS), peak-signal-noise-ratio (PSNR)], QoE is more concerned about user's subjective experience. Accordingly, a user-centric quality strategy brings an increasing popularity of QoE-driven applications in the multimedia domain. Therefore, in this paper, we present the latest development of QoE in the multimedia domain. Specifically, we first introduce the background of QoE, including the definitions of QoE and the relationship between QoS and QoE. Then, we explain the influence factors of QoE in detail, which are the basis of QoE modelling and prediction. Subsequently, we mainly present typical latest research work about QoE measurement and modelling in recent years. Moreover, we also exhibit our research work about QoE-driven multimedia applications. Finally, open challenges and research directions are presented in the conclusion for future studies.

Keywords: quality of experience; QoE; quality of service; QoS; user-centric experience; multimedia domain.
