“…Similarly it can calculate the disparity matrix of right eye M rpar . (14) M lpar and M rpar are shear transformation matrix. Therefore, the formation of binocular images can be vieitd as the shear transformation in single camera space, and then the conventional projection, finally it can see that shear transformation is symmetric.…”

“…People have done more research on the generation mechanism of visual fatigue [3,6,[13][14][15]. A common view is: the human eye adjustment and convergence is a tightly coupling, but when watching the stereoscopic images, it will lead to the separation of adjustment and convergence.…”

“…A common view is: the human eye adjustment and convergence is a tightly coupling, but when watching the stereoscopic images, it will lead to the separation of adjustment and convergence. Large regulation conflicts cause visual discomfort or fatigue [13,14]. Patterson suggested in the production of stereo image, perceived depth should be limited within DOF (Depth of Field) [2].…”

For real-time stereo vision system, this paper analyzes the parallax generation mechanism of the virtual camera imaging; it presents projection transform of binocular images in single camera space. At the same time it changes the control depth perception by introducing camera wheelbase into bending deformation of the object, which can ensure the continuity of non-uniform compression ratio. The method is simple and flexible. The experimental results show that the depth mapping method will not visually produce distortion,which can effectively improve the quality of image. This method is a 3D graphics development for virtual reality and real-time game rendering, and it can be applied to 3D computer animation. When rendering stereo image, it can use this method to control the depth, which can reduce the amount of complicated work in post-production.

“…Therefore, several subjective experiments have been carried out analyzing different factors related to watching 3D content. Especially important are those studies concerning visual discomfort or fatigue [6], commonly experienced by the viewers of 3D video and caused by the use of glasses, motion artifacts [14], and vergence-accommodation conflicts [15]. Depth perception is other factor affecting 3D video visualization that is being deeply investigated [16], as well as distortions introduced by 3D visualization technologies, like crosstalk between views [17], [18].…”

Abstract-This paper presents a comparison among different consumer 3D display technologies by means of a subjective assessment test. Therefore, four 55-in displays have been considered: one autostereoscopic display, one stereoscopic with polarized passive glasses, and two with active shutter glasses. In addition, a high-quality 3D video database has been used to show diverse material with both views in high definition. To carry out the test, standard recommendations have been followed considering also some modifications looking for a test environment more similar to real home viewing conditions, with the objective of obtaining more representative conclusions. Moreover, several perceptual factors have been considered to study the performance of the displays, such as picture quality, depth perception, and visual discomfort. The obtained results show interesting issues, like the performance improvement of active shutter glasses technology, the high performance of the polarized glasses technology in terms of quality and comfort, and the need of improvement of the autostereoscopic displays to complement the visual comfort to reach a global high-quality visual experience.Index Terms-Depth perception, quality of experience, subjective evaluation, 3D displays, visual discomfort.

“…In [5], visually evoked potentials in EEG were examined to detect fatigue, where it was shown that the P100 latency (i.e., 100 msec after the stimulus onset) can be used for a fatigue index. The study in [22] showed that the power of the high frequency EEG bands and the changes of the P700 component (i.e., amplitude 700 msec after the stimulus onset) are strong candidates for measuring 3D visual fatigue.…”

As immersive technologies target to provide higher quality of multimedia experiences, it is important to understand the quality of experience (QoE) perceived by users from various multimedia rendering schemes, in order to design and optimize human-centric immersive multimedia systems. In this study, various QoE-related aspects, such as depth perception, sensation of reality, content preference, and perceived quality are being investigated and compared for presentation of 2D and 3D contents. Since the advantages of implicit over explicit QoE assessment have become essential, the way these QoE-related aspects influence brain and periphery is also investigated. In particular, two classification schemes using electroencephalography (EEG) and peripheral signals (electrocardiography and respiration) are carried out, to explore if it is possible to automatically recognize the QoE-related aspects under investigation. In addition, a decision-fusion scheme is applied to EEG and peripheral features, to explore the advantage of integrating information from the two modalities. The results reveal that the highest monomodal average informedness is achieved in the high beta EEG band (0.14% ± 0.09, p < 0.01), when recognizing sensation of reality. The highest and significantly non-random multimodal average informedness is achieved in when high beta EEG band is fused with peripheral features (0.17% ± 0.1, p < 0.01), for the case of sensation of reality. Finally, a temporal analysis is conducted to explore how the EEG correlates for the case of sensation of reality change over time. The * Refers to the corresponding author. The research leading to these results has been performed in the framework of Swiss National Foundation for Scientific Research (FN 200020-132673-1 and FN 200021-143696-1) results reveal that that the right cortex is more involved when sensation of reality is low, and the left one when sensation of reality is high, indicating that approach and withdrawal-related processes occur during sensation of reality.
