Effect of local crosstalk on depth perception

SPIE Proceedings, 2014
Interocular crosstalk has a significant undesirable effect on the quality of 3D displays that utilize horizontal disparity. This study investigates observer sensitivity when judging the depth order of two horizontally aligned dots on a 3D display and assesses 3D display uniformity by obtaining this index for various locations on the display.

Phase Quantization in Holograms–Depth Effects

Applied Optics, 1972
A three-dimensional holographic image is deteriorated due to quantization of the phase in the hologram. As in two-dimensional Fourier holograms, the deterioration is exhibited as a superposition of false images. However, in the three-dimensional case, the false images fall at depth positions other than the plane of the image to which they correspond ...

Simulation of sparkling and depth effect in paints

Proceedings of the 19th Spring Conference on Computer Graphics, 2003
This paper reports on our attempts to simulate light reflection from surfaces that exhibit sparkling and depth effects that are associated with paint coatings containing metallic flakes. The novelty of the approach is to explicitly model the sparkle geometry for rendering the surface of a graphic object.

Anisotropy in an ambiguous kinetic depth effect

Journal of the Optical Society of America A, 1992
A set of animated stimuli (Lissajous figures), each element of which is physically consistent with two different three-dimensional shapes undergoing rigid rotations about orthogonal axes, is described. Human observers typically show a preference for one shape or the other; this preference may be biased by manipulating various parameters of the stimulus.

Vergence effects on the perception of motion-in-depth

Experimental Brain Research, 2007
When the eyes follow a target that is moving directly towards the head they make a vergence eye movement. Accurate perception of the target's motion requires adequate compensation for the movements of the eyes. The experiments in this paper address the issue of how well the visual system compensates for vergence eye movements when viewing moving ...

Effects of Depth Cues on Simulator Sickness

Proceedings of the ImmersCom, 2007
In this paper, we discuss our experimental results on Simulator Sickness (SS). A series of experiments were conducted in our Virtual Reality (VR) Lab. Our aim was to investigate the correlations between the perception of depth and the feeling of discomfort, as well as the role of gameplay regarding the familiarity of the viewer with computer games in ...

Perceptual Invariance in the Kinetic Depth-Effect

The American Journal of Psychology, 1965
Under appropriate conditions, a continuous sequence of shadow-transformations will yield the appearance of a rigid form, having internal depth and turning in space. This is the kinetic depth-effect (K.DE) studied by Wallach and O'Connell.1 Wallach's experiments and the related literature have been reviewed by Braunstein.2 A peripheral result reported ...

Effect of meridional disparity on depth perception

Journal of the Optical Society of America, 1979
When a meridional-size lens is used to provide magnification in the horizonal meridan for one eye the resulting stereopsis distortion is readily accounted for in the terms of the binocular disparity caused by changed angular relations. When the same size lens is used to magnify the vertical meridian for one eye there is an opposite stereoscopic ...

The Effects of Depth of Knowledge of a Virtual Agent

IEEE Transactions on Visualization and Computer Graphics
We explored the impact of depth of knowledge on conversational agents and human perceptions in a virtual reality (VR) environment. We designed experimental conditions with low, medium, and high depths of knowledge in the domain of game development and tested them among 27 game development students.
