the actual image. This is accomplished by prestoring the
positions and geometric features of the real objects in a
computer spatial model of the space (specification, page 3,
lines 32-36), thus eliminating retrieval of stationary objects
from storage.
Independent claim 1 is reproduced as follows:
1. Apparatus for providing a virtual reality environment
with images of virtual objects provided in response to sensed
actions of a viewer wherein the images of virtual objects lag
after the sensed actions of the viewer, comprising:
a head mounted camera (10) for mounting on a head (12) of
the viewer acting as a cameraman for gathering images of real
objects from a moving perspective of the viewer, said camera
responsive to reflected light from the real objects in an
object space, for providing a real object image signal (14)
indicative of the real objects;
an image store (22), responsive to a selection signal
(20), for providing a prestored virtual object image signal
(24) indicative of moving virtual objects;
a computer and image processor (16) having positions and
geometric features of said real objects prestored in a
computer spatial model of the object space, responsive to a
plurality of monitor signals for providing the selection
signal (20) and responsive to the real object image signal
(14) and the virtual object image signal (24), for providing
an integrated image signal (26) indicative of both said real
objects and said virtual objects;
