Abstract

The current document is directed to a virtual-reality system, and methods incorporated within the virtual-reality system, that provides a scalable physical volume in which human participants can freely move and assume arbitrary body positions while receiving electronic signals that are rendered to the human participants by virtual-reality rendering appliances to immerse the human participants in a virtual environment. In a described implementation, the virtual-reality system includes multiple networked optical sensors, a computational tracking system, networked virtual-reality engines, and virtual-reality rendering appliances.

Claims

1. A virtual-reality presentation volume comprising:

a scalable, physical volume in which participants can free move and assume arbitrary orientations;

a motion-capture system that continuously determines the positions of markers and the orientations of multi-marker patterns attached to participants and objects in the scalable, physical volume;

a network of virtual-reality engines that receive position and orientation data from the motion-capture system, compute position, orientation, velocity, acceleration, and projected position information for virtual-reality-environment participants and objects, and transfer the position, orientation, velocity, acceleration, and projected position information to virtual-reality applications executing within the virtual-reality engines; and

virtual-reality rendering appliances that receive, by wireless communication, virtual-reality-environment data generated by the virtual-reality applications executing within the virtual-reality engines and that render the received virtual-reality-environment data to provide a virtual-reality environment to participants wearing the virtual-reality rendering appliances.
