A Study on the Factors Affecting Audio-Video Subjective Experience in Virtual Reality Environments

Virtual Reality brings a new experience in visual and auditory. Immersive experience in virtual reality is not only from the visual feeling of panoramic video, spatial audio also plays a vital role. Unfortunately, combination quality assessment of panoramic video and spatial audio is still lacking. In this paper, we propose a subjective experimental methodology to prove the influence of four impairment types on subjective experience, including video and audio impairment, temporal and spatial synchronization. Subjective experiment is conducted and the results verify that the four impairment types have different influence degree on user experience.
