Study on the quality of experience evaluation metrics for astronaut virtual training system

Abstract

With the development of virtual reality (VR) technology, it is possible to train astronauts using VR. To make the system more efficient, it is necessary to study the quality of experience (QoE) of astronauts in the virtual environment (VE). Based on the characteristics of virtual training system and the needs of astronauts training, a set of metrics consisting of five higher-level metrics and fifteen lower-level metrics were put forward for the QoE evaluating of the system. In addition, the weight of each higher-level metrics is obtained using analytic hierarchy process (AHP) method. The results of this paper can be used directly in the QoE evaluation of astronaut virtual training system in a quantitative way.
