Quality of Experience “QoE†represents human centric approach to assess quality of any service or product to understand user needs, feelings, performance and overall user experience. In this article, we propose a generalized QoE Interaction Model which comprises of three domains, QoE-contextual-, QoE-technological- and QoE-business-domain. Furthermore, we particularly investigate the impact of contextual domain over QoE domain. As a case study we investigate “3D Telephony†on the basis of QoE requirements of users/customers. 3D Telephony is an open source VoIP based 3D audio telephone and teleconference service. User studies were conducted to capture QoE data. Benchmarking of QoE terms, their analysis and validation in three different test scenarios were done using statistical empirical approaches. This whole study brought interesting results and QoE findings.
