(figure 1, item numbered 18) provide sensed signals indicative
of viewer movements within the object space to the computer
and image processor. In response to the sensed signals the
computer and image processor provide virtual object selection
signals on a line (figure 1, item numbered 20) to a virtual
object image store (figure 1, item numbered 22) which contains
a plurality of scenarios containing images of one or more
virtual objects. The selected scenario is output on a line
(figure 1, item numbered 24) to the computer and image
processor where images of the virtual objects are integrated
with the images of the real objects provided on line 14. The
integrated image signal is provided on a line (figure 1, item
numbered 26) to a head mounted display (figure 1, item
numbered 28) worn by the viewer in the object space.
Disconcerting time lag between the viewer's actions in an
empty virtual environment filled with virtual objects and the
response of the imaging system (specification, page 2, lines
29-32) is minimized by using images from the head-mounted
camera to be displayed on the head-mounted viewer, and by
using images imitative of virtual objects moving in the object
space which are retrieved from storage and are integrated with
