    The author presents a personal assessment of the state of the art of VR. In 1994, he surveyed the field of VR. His assessment then was that VR almost worked, but that we were not yet there. There were lots of demos and pilot systems, but except for vehicle simulators and entertainment applications, VR was not yet in production use doing real work. This year he was invited to do an up-to-date asses... View full abstract»

    I'm interested in both the answer to the question in the title and in finding the clearest possible derivation of that answer. My first efforts were very algebra-intensive, but had an aura of concreteness about them. As I played with the question, I came up with more and more elegant ways to ward off the brute-force algebra and make the answer more intuitive without reams of calculation. For these...

    We assume that in the future any user's display platform can render fantastically complex scenes. Having finally shed the concerns related to the computer graphics medium, developers will concentrate on the message. Content will be key-no longer will users accept nonsensical, artistically vacant environments simply because they're presented in a head-mounted display. This will also mean that stati...

    Virtual Assembly Design Environment (VADE) resulted from a research and development project started in 1995, sponsored by the National Institute of Standards and Technology (NIST). The main purpose of this project was to explore the potential and the technical challenges in using VR technologies for design and manufacturing by creating a VE for assembly planning and evaluation. In this article, we... View full abstract»

    Locomotion in virtual environments (VEs) remains one of the major problems in current virtual reality research. The most intuitive way to move about the real world is to travel on foot. People often feel a better sense of distance or direction while walking than while riding in a vehicle. This article discusses the development of a locomotion device that provides a sense of walking. In terms of na... View full abstract»

  • The NYSE's 3D Trading Floor

    The 3D Trading Floor lets people use one of their strongest innate skills-spotting exceptions. A good visualization system leverages this ability by bringing exceptions to the fore. The model shows data on many different levels. Because it's designed for the floor operations staff, as opposed to individual traders, it focuses on operational issues. So it depicts the floor of the New York Stock Exc... View full abstract»

    Bisector construction plays an important role in many geometric computations. This article explains how to compute rational bisectors of point-surface and sphere-surface pairs. This article shows that the bisector of a point and a rational surface in R3 (3D space) is also a rational surface. This result implies that the bisector of a sphere and a surface with a rational offset is also a... View full abstract»

    We present a structured, iterative methodology for user-centered design and evaluation of VE user interaction. We recommend performing (1) user task analysis followed by (2) expert guidelines-based evaluation, (3) formative user-centered evaluation, and finally (4) comparative evaluation. In this article we first give the motivation and background for our methodology, then we describe each techniq... View full abstract»

    Our work stems from a program focused on developing tracking technologies for wide-area augmented realities in unprepared outdoor environments. Other participants in the Defense Advanced Research Projects Agency (Darpa) funded Geospatial Registration of Information for Dismounted Soldiers (Grids) program included University of North Carolina at Chapel Hill and Raytheon. We describe a hybrid orient... View full abstract»

    The Round Earth Project is a collaboration among researchers in computer science, education, and psychology. It investigates two alternative pedagogical strategies for teaching children that the Earth is spherical and the implications of that fact. One strategy, which we term the transformationalist approach, attempts to effect conceptual change by breaking down the children's prior models. In con... View full abstract»

    This report summarizes results of the first EC/NSF joint Advanced Research Workshop, which identified key research challenges and opportunities in information technology. The group agreed that the first joint research workshop should concentrate on the themes of human-centered computing and VEs. Human-centered computing is perceived as an area of strategic importance because of the move towards gr... View full abstract»
