Statistical analysis of questionnaire survey on the assessment of 3D video clips

Abstract

Several studies have been conducted on visual fatigue and visually induced motion sickness. However, no assessments have been conducted to compare 2D or 3D images or video clips. Although certain studies focused on determining the influences of viewing 3D images, there has been no unified assessment method or standard regarding 3D video clips. Moreover, prior research have demonstrated the assessment examples for only one 3D system. However, there have been no assessments comparing multiple 3D systems. Thus, the comfort of the viewing experience of multi-view 3D systems is yet to be clarified. Previously, the assessments on 3D video clips and multiple 3D systems have not considered the viewer’s personal attributes such as sex, corrected eyesight, and user experience. Thus, we initially conducted a questionnaire survey on 168 subjects regarding their experience with 3D video clips. Subsequently, we performed an experiment on 3D video assessments of 92 subjects with three display types, portraying the same 3D computer graphics content. Ultimately, the statistical analysis of the experimental results revealed the influence of age generations and individual characteristics on visually induced motion sickness.
