A method and apparatus for providing, in response to image signals
originating in an object space, mixed image signals for providing
nonuniform resolution images for stimulating simulated active percepts
for passive perception by a viewer in an image space. The images have a
highly detailed component which has its image content changed according
to changes in the direction of a simulated observer's eye position in an
object space. The images may be provided stereoscopically. The images may
be provided at various apparent distances and the relationship between
accommodation and convergence may be preserved. Audio waves for
directionally simulating that which would be heard by the simulated
observer may be provided.
