- This paper gives an overview of three recent studies by the authors on the topic of 3D video Quality of Experience (QoE). Two of studies [1,2] investigated different psychological dimension that may be needed for describing 3D video QoE and the third the visibility and annoyance of crosstalk[3]. The results shows that the video quality scale could be sufficient for evaluating S3D video experience for coding and spatial resolution reduction distortions. It was also confirmed that with a more complex mixture of degradations more than one scale should be used to capture the QoE in these cases. The study found a linear relationship between the perceived crosstalk and the amount of crosstalk.

- The stereoscopic 3D viewing experience has been studied quite intensively recently; however the subjective test methods to assess it have not been determined. It has become clear that the 3D viewing experience cannot easily be described by just one scale. This paper describes a cross-laboratory study employing the same test setup and materials where a multi-scale rating method was used. One of the laboratories used three scales: Depth Naturalness, Visual Comfort and Video Quality; while the other laboratory used these: 3D Realism, Depth Quantity and Video Quality. The results show that the Quality of Experience (QoE) of 3D video is a multidimensional concept and therefore more than one scale is in many cases needed for subjective assessment of the QoE of 3D video.
