Descriptive Quality of Experience for Mobile 3D Video

摘要

Perceptual quality evaluation experiments are used to assess the excellence of multimedia quality. However, these studies disregard qualitative experiential descriptions, interpretations, and impressions of quality. The goal of this paper is to identify general descriptive characteristics of experienced quality of 3D video on mobile devices. We conducted five studies in which descriptive data was collected after the psychoperceptual quality evaluation experiment. Qualitative semi-structured interviews and written attribute description tasks were conducted with over 90 naive participants. The experiments contained an extensive and heterogeneous set of produced quality by varying content, level of depth, compression and transmission parameters, and audio and display factors for 3D. The results showed that quality of experience is constructed from four main components, 1) visual quality, 2) viewing experience, 3) content, and 4) quality of other modalities and their interactions.
