ABSTRACT:
An improved device for determining the three-dimensional location and orientation of a subject in a virtual reality simulation is a hybrid of an optical localization system and independent tilt and direction sensors. Three or more modulated sources of light or near-infrared radiation are placed at the perimeter of the sensing volume; these sources are typically emitters surrounded by rotating cylindrical grating. A single photosensor extracts enough information from the radiation field to derive position within the volume. Orientation is sensed by small gravitational tilt and magnetic compass direction sensors. Since the sensing is entirely passive, any number of objects can be tracked within the volume as long as at least three of the sources are visible from the position of each object.
