The Quality of Experience (QoE) is a key element in the search for rapid growth of three-dimensional video technology. Research concerning the study of QoE in a 3D environment is on the move. This paper proposes a review of 3D QoE specificities. We will also present the actual findings in this area as well as the projects in process around the world. Thus, any researcher wishing to know more about this domain will be able to start with the foundations necessary to understand the issues related to 3D.
