“…At the heart of VR technology is the displays, which help create stereoscopic views and deeply immersive environments for users. Stereoscopic viewing can be effected by either polarization techniques or time‐multiplexed 3D displays . Viewers may use either polarized (or shutter glasses) or 3D glasses respectively for active or passive views .…”

In this paper, authors systematically selected and reviewed articles related to stereoscopic displays and their advances, with a special focus on perception, interaction, and corresponding challenges. The aim was to understand interaction‐related problems, provide possible explanations, and identify factors that limit their applications. Despite promising advancements, there are still issues that researchers in the field fail to explain precisely. The two major problems in stereoscopic viewing are, compared with the real world, objects are perceived to be smaller than they actually are and there are discomfort and visual syndromes. Furthermore, there is general agreement that humans underestimate their egocentric distance in a virtual environment (VE). Our analysis revealed that in the real world, distance estimation is about 94% accurate, but in VE, it is only about 80% accurate. This problem could reduce the efficacy of different sensory motor‐based applications where interaction is important. Experts from human factors, computing, psychology, and others have studied contributing factors such as types of perception/response method, quality of graphics, associated stereoscopic conditions, experience in virtual reality (VR), and distance signals. This paper discusses the factors requiring further investigation if the VR interaction is to be seamlessly realized. In addition, engineering research directions aiming at improving current interaction performances are recommended.

“…The perception of depth depends on the combination of multiple cues, whose reliability changes with the distance of the object to the observers (Gilinsky, 1951 ; Da Silva, 1985 ; Nagata, 1991 ; Landy et al, 1995 ; Loomis et al, 1996 ; Loomis and Knapp, 2003 ; Swan et al, 2007 ; Armbrüster et al, 2008 ; Saracini et al, 2009 ; Naceri et al, 2011 ). A cue of primary importance is the angular size, defined as the size of the image that an object produces on the retina of the observer.…”

In our daily life experience, the angular size of an object correlates with its distance from the observer, provided that the physical size of the object remains constant. In this work, we investigated depth perception in action space (i.e., beyond the arm reach), while keeping the angular size of the target object constant. This was achieved by increasing the physical size of the target object as its distance to the observer increased. To the best of our knowledge, this is the first time that a similar protocol has been tested in action space, for distances to the observer ranging from 1.4–2.4 m. We replicated the task in virtual and real environments and we found that the performance was significantly different between the two environments. In the real environment, all participants perceived the depth of the target object precisely. Whereas, in virtual reality (VR) the responses were significantly less precise, although, still above chance level in 16 of the 20 observers. The difference in the discriminability of the stimuli was likely due to different contributions of the convergence and the accommodation cues in the two environments. The values of Weber fractions estimated in our study were compared to those reported in previous studies in peripersonal and action space.

“…Roughly speaking, it seems that partial occlusion (an object partially in front of another one) is one of the most important factors whatever the distance between the person and the object. For limited distances (less than 40m), binocular disparities associated with stereoscopic vision and perspective motions also have an important effect, whereas for larger distances -not considered in this paper-other factors like aerial perspective come into play ( [17], [18]).…”

3D drawing problems of the 90s were essentially restricted on representations in 3D perspective. However, recent technologies offer 3D stereoscopic representations of high quality which allow the introduction of binocular disparities, which is one of the main depth perception cues, not provided by the 3D perspective. This paper explores the relevance of stereoscopy for the visual identification of communities, which is a task of great importance in the analysis of social networks. A user study conducted on 35 participants with graphs of various complexity shows that stereoscopy outperforms 3D perspective in the vast majority of the cases. When comparing stereoscopy with 2D layouts, the response time is significantly lower for 2D but the quality of the results closely depend on the graph complexity: for a large number of clusters and a high probability of cluster overlapping stereoscopy outperforms 2D whereas for simple structures 2D layouts are more efficient.
