The most effective layout of the planes can be determined based on the relative locations of an observer's viewing position, multiple cameras, and 3D objects. A method is described for controlling the LOD of the 3D representation by adjusting the orientation, interval, and resolution of planes. The data size of the 3D model and the processing time can be reduced drastically. The effectiveness of the proposed method is demonstrated by experimental results.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.

The system addresses three main applications: preparation for the visit of an existing site, training for the use of a blind cane, and ludic exploration of virtual worlds. The HOMERE system provides the user with different sensations when navigating inside a virtual world: a force feedback corresponding to the manipulation of a virtual blind cane, a thermal feedback corresponding to the simulation of a virtual sun, and an auditory feedback in spatialized conditions corresponding to the ambient atmosphere and specific events in the simulation. A visual feedback of the scene is also provided to enable sighted people to follow the navigation of the main user.

Since the PC cluster environment presents application development constraints, it is impossible to simultaneously optimize for efficiency, flexibility, and portability between the single-computer and cluster cases. Consequently Syzygy includes two application frameworks: a distributed scene graph framework for rendering a single application's graphics database on multiple rendering clients, and a master/slave framework for applications with multiple synchronized instances. Syzygy includes a simple distributed OS and supports networked input devices, sound renderers, and graphics renderers, all built on a robust networking layer.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.

Our primary contribution is the creation of a virtual reality system that tracks the full body in a working volume of 4 meters by 5 meters by 2.3 meters high to produce an animated representation of the user with 42 degrees of freedom. This - combined with a lightweight (<3 pounds) belt-worn video receiver and head-mounted display - provides a wide area, untethered virtual environment that allows exploration of new application areas. Our secondary contribution is our attempt to show that user interface techniques made possible by such a system can improve training for a full body motor task. We tested several immersive techniques, such as providing multiple copies of a teacher's body positioned around the student and allowing the student to superimpose his body directly over the virtual teacher None of these techniques proved significantly better than mimicking traditional Tai Chi instruction, where we provided one virtual teacher directly in front of the student. We consider the implications of these findings for future motion training tasks.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.

Compared to infrastructure-based trackers, self-trackers have the advantage that objects can be tracked over an extremely wide area, without the prohibitive cost of an extensive network of sensors or emitters to track them. So far, most AR research has focused on the long-term goal of a purely vision-based tracker that can operate in arbitrary unprepared environments, even outdoors. We instead chose to start with artificial fiducials, in order to quickly develop the first self-tracker which is small enough to wear on a belt, low cost, easy to install and self-calibrate, and low enough latency to achieve AR registration. We also present a roadmap for how we plan to migrate from artificial fiducials to natural ones. By designing to the requirements of AR, our system can easily handle the less challenging applications of wearable VR systems and robot navigation.","PeriodicalId":105245,"journal":{"name":"IEEE Virtual Reality, 2003.
