“…With polarization-based LCS and PPF setups, although full-color viewing of dichoptic stimuli is enabled, these methods can also cause the images to physically darken (Choubey et al, 2009;Pastoor & Wöpking, 1997;Stevens, 2004). For ATS displays, a number of related issues to consider include the following: (1) reduced image brightness in parallax ATS displays as half of the subpixel columns are blocked by the barrier (Choubey et al, 2009;Pastoor & Wöpking, 1997); (2) interpixel gaps (i.e., black mask matrix) in lenticular-type displays can be projected, causing dark regions to appear between observation zones (Holliman et al, 2011; though it can be resolved by slanting the monitor's lenticular lenses: Lipton & Feldman, 2002;Lipton et al, 1985;Lueder, 2011;van Berkel & Clarke, 1997); and (3) light scatter at lenticular lens boundaries causing variation in illumination intensity (Hill & Jacobs, 2006). Furthermore, because half of ATS monitor pixels are viewed by each eye, horizontal spatial resolution of each image is reduced by 50%.…”

Dichoptic Viewing Methods for Binocular Rivalry Research: Prospects for Large-Scale Clinical and Genetic Studies

Binocular rivalry (BR) is an intriguing phenomenon that occurs when two different images are presented, one to each eye, resulting in alternation or rivalry between the percepts. The phenomenon has been studied for nearly 200 years, with renewed and intensive investigation over recent decades. The rate of perceptual switching has long been known to vary widely between individuals but to be relatively stable within individuals. A recent twin study demonstrated that individual variation in BR rate is under substantial genetic control, a finding that also represented the first report, using a large study, of genetic contribution for any post-retinal visual processing phenomenon. The twin study had been prompted by earlier work showing BR rate was slow in the heritable psychiatric condition, bipolar disorder (BD). Together, these studies suggested that slow BR may represent an endophenotype for BD, and heralded the advent of modern clinical and genetic studies of rivalry. This new focus has coincided with rapid advances in 3D display technology, but despite such progress, specific development of technology for rivalry research has been lacking. This review therefore compares different display methods for BR research across several factors, including viewing parameters, image quality, equipment cost, compatibility with other investigative methods, subject group, and sample size, with a focus on requirements specific to large-scale clinical and genetic studies. It is intended to be a resource for investigators new to BR research, such as clinicians and geneticists, and to stimulate the development of 3D display technology for advancing interdisciplinary studies of rivalry.

This paper proposes an alternative approach to common teleoperation methods found in search and rescue (SAR) robots. Using a head mounted display (HMD) the operator is capable of perceiving rectified images of the robot world in 3-D, as transmitted by a pair of stereo cameras onboard the robot. The HMD is also equipped with an integrated head-tracker, which permits controlling the robot motion in such a way that the cameras follow the operator's head movements, thus providing an immersive sensation to him. We claim that this approach is a more intuitive and less error prone teleoperation of the robot. The proposed system was evaluated by a group of subjects, and the results suggest that it may yield significant benefits to the effectiveness of the SAR mission. In particular, the user's depth perception and situational awareness improved significantly when using the HMD, and their performance during a simulated SAR operation was also enhanced, both in terms of operation time and on successful identification of objects of interest.

“…Specific rendering algorithms for multi-view auto-stereoscopic displays have not been proposed so far, however, methods used for two-view stereo rendering [Hodges and McAllister 1993;Hill and Jacobs 2006] can be multiplied and applied to N -view auto-stereo rendering. In stereo rendering environments, generally the displayed 3D data set is rendered twice, once for each left/right eye view.…”

The fundamental drawback of current stereo and multi-view visualization is the necessity to perform multi pass rendering (one pass for each view) and subsequent image composition + masking for generating multiple stereo views. Thus the rendering time increases in general linearly with the number of views. In this paper we introduce a new method for multi-view splatting based on deferred blending. Our method exploits the programmability of modern graphic processing units (GPUs) for rendering multiple stereo views in a single rendering pass. The views are calculated directly on the GPU including sub-pixel wavelength selective views. We describe our algorithm precisely and provide details about its implementation. Experimental results demonstrate the performance advantage of our multi-view point splatting algorithm compared to the standard multi-pass approach.
