A Subjective Perceptual Quality Evaluation for Emerging Cloud VR Services
Mingyi Yang, Wenjie Zou, Fuzheng Yang · 2019
Cloud virtual reality (VR) is an emerging solution for VR applications. This technology can significantly reduce the requirement of the high computational capacity of the VR terminal and is conducive to the promotion of virtual reality services. Accurately measuring user's perceptual quality of cloud VR services is urgently demanded by VR service providers and network operators to further improve their quality of service. So far, there is still a lack of research about user's perceptual quality of cloud VR services. In this paper, we conducted a subjective experiment to investigate the impact of frame rate on the perceptual quality of the artificial scene and captured real scene in cloud VR services. Experimental results reveal that different frame rates have different influence on users' perceptual quality. Moreover, it is found that users' perceptual quality for the artificial scene and the captured real scene do not have significant difference.
