From QoS to QoE: Towards Experience-Centric Evaluations of Tele-Immersive Environments

Опубликовано 4 августа 2016, 17:56

We are seeing a rapid growth of tele-immersive environments over the last decade with applications ranging from health care, training to entertainment. Despite their intensity of user-involved interactions, many of the existing evaluation frameworks remain mostly system-centric, utilizing Quality of Service (QoS) evaluation metrics. Over the last few years we are also seeing intensified efforts towards experience-centric approaches, utilizing Quality of Experience (QoE) evaluation metrics. These efforts are moving in the right direction of understanding evaluations of tele-immersive environments from the experiential point of view. However, the journey towards experience-centric evaluation of tele-immersive environments is very challenging due to (a) multi-modal media in tele-immersive environments, (b) multitude of underlying end-to-end networking and computational technologies, and (c) diverse human activities conducted and experienced in these immersive spaces.
