We present the two-user Responsive Workbench: a projection-based virtual reality system that allows two people to simultaneously view individual stereoscopic image pairs from their own viewpoints. The system tracks the head positions of both users and computes four images-one for each eye of each person. To display the four images as two stereo pairs, we(More)
Confocal microscopy is a family of imaging techniques that employ focused patterned illumination and synchronized imaging to create cross-sectional views of 3D biological specimens. In this paper, we adapt confocal imaging to large-scale scenes by replacing the optical apertures used in microscopy with arrays of real or virtual video projectors and cameras.(More)
As wider field-of-view displays become more common, the question arises as to whether or not data collected on these displays are comparable to those collected with smaller field-of-view displays. This document describes a pilot study that aimed to address these concerns by comparing medium-field distance judgments in a 60° FOV display, a 150° FOV(More)
In the good old days, the human was here, the computer there, and a good living was to be made by designing ways to interface between the two. Now we find ourselves unthinkingly pinching to zoom in on a picture in a paper magazine. User interfaces are changing instinctual human behavior and instinctual human behavior is changing user interfaces. We point or(More)
The Flexible Action and Articulated Skeleton Toolkit (FAAST) is middleware to facilitate integration of full-body control with virtual reality applications and video games using OpenNI-compliant depth sensors (currently the PrimeSensor and the Microsoft Kinect). FAAST incorporates a VRPN server for streaming the user's skeleton joints over a network, which(More)
Natural walking can provide a compelling experience in immersive virtual environments, but it remains an implementation challenge due to the physical space constraints imposed on the size of the virtual world. The use of redirection techniques is a promising approach that relaxes the space requirements of natural walking by manipulating the user's route in(More)
Figure 1: A 3D object shown on the display is photographed by two stereo cameras (seen in the middle image). The two stereo viewpoints sample the 360 • field of view around the display. The right pair is from a vertically-tracked camera position and the left pair is from an untracked position roughly horizontal to the center of the display. The stereo pairs(More)
We present a set of algorithms and an associated display system capable of producing correctly rendered eye contact between a three-dimensionally transmitted remote participant and a group of observers in a 3D teleconferencing system. The participant's face is scanned in 3D at 30Hz and transmitted in real time to an autostereoscopic horizontal-parallax 3D(More)
PURPOSE This paper details a brief history and rationale for the use of virtual reality (VR) technology for clinical research and intervention, and then focuses on game-based VR applications in the area of rehabilitation. An analysis of the match between rehabilitation task requirements and the assets available with VR technology is presented. KEY(More)
