| Popis: | Recent advances in video technology and digital cinema have made it possible to produce entertaining 3D stereoscopic content that can be viewed for an extended duration without necessarily causing extreme fatigue, visual strain and discomfort. Viewers focus naturally their attention on specific areas of interest in their visual field. Visual attention is an important aspect of perception and its understanding is therefore an important aspect for the creation of 3D stereoscopic content. Most of the studies on visual attention have focused on the case of still images or 2D video. Only a very few studies have investigated eye movement patterns in 3D stereoscopic moving sequences, and how these may differ from viewing 2D video content. In this paper, we present and discuss the results of a subjective experiment that we conducted using an eye-tracking apparatus to record observers' gaze patterns. Participants were asked to watch the same set of video clips in a free-viewing task. Each clip was shown in a 3D stereoscopic version and 2D version. Our results indicate that the extent of areas of interests is not necessarily wider in 3D. We found a very strong content dependency in the difference of density and locations of fixations between 2D and 3D stereoscopic content. However, we found that saccades were overall faster and that fixation durations were overall lower when observers viewed the 3D stereoscopic version. |
