Influence of depth rendering on the quality of experience for an autostereoscopic display
Autostereoscopic displays simplify the presentation of 3D content because they do not require any glasses and they allow the perception of motion parallax. While the perception of depth is certainly an added value, the technical rendering process of the current display technology also introduces artifacts. For the viewer, the tradeoff may be expressed in terms of quality of experience. However, quality of experience assessment related to 3D is still an open issue. Towards this goal, several original subjective test methods are proposed and compared that are meant for assessing the quality of experience. A split-screen setup simultaneously displays a 2D and a 3D presentation. The observers vote according to their preference in terms of quality of experience. In four experiments, the influence of the depth rendering process is evaluated. The results indicate that the degradation by the depth rendering process may easily dominate the added value of depth in a content specific manner.
