In observing a 3D virtual object displayed stereoscopically on a large-sized screen, there often exists a difference between the calculated depth and the perceived one of the object. This paper presents a method for reducing such differences of depth. ...

This study investigates human performance when using semitransparent tools in interactive 3D computer graphics environments. The article briefly reviews techniques for presenting depth information and examples of applying semitransparency in computer ...

Autostereoscopic 3-D imaging and display system is implemented on the notebook 486 DxII PC with TFT active matrix LCD display module and accompanying lenticular sheet lens. An image processing board (e.g. Targa Plus which is commercially available) is ...

Perceptual transparency is the visual experience of two or more apparently superimposed physical surfaces. When transparency is perceived, psychophysical evidence demonstrates effects on depth relationships suggestive of early interaction. Why should ...

When presenting virtual images to a user performing a simple task requiring depth perception, the use of stereoscopic projections results in a ten-fold reduction in mean alignment error as compared to the use of monocular projections. Although average ...

Given the profiles of a moving, solid object it is possible to perceive the shape and motion of an object moving in three dimensions. I investigated both the theory of recovering shape from profiles as well as human competence at extracting shape from ...

This thesis presents a new approach to the problem of constructing a depth map from a sequence of monocular images. The approach only requires accurate knowledge of the robot's motion along the focal axis of the moving camera. When the configuration of ...
