1. A method comprising: receiving at least one tracking signal indicative of tracked navigational movements of a device navigated in motion in an object space with both device orientation movements with respect to a three-dimensional reference frame of said object space and device translatory position movements with respect to said three-dimensional reference frame of said object space, wherein said device translatory position movements comprise three-dimensional translations in position of said device with respect to said three-dimensional reference frame of said object space, providing, in response to said tracking signal, a light control signal comprising successive computer generated images with a changing image direction of view and a moving image point of view with respect to a three-dimensional image space frame of reference in correspondence, respectively, with a changing device direction of view and a moving device point of view acquired in correspondence with said tracked navigational movements of said device with both said device orientation movements and with said device translatory position movements in said object space with respect to said three-dimensional reference frame of said object space, said successive computer generated images made for viewing in an image space separate from said object space and made for viewing in said image space in a passive viewing role, and storing said light control signal comprising said successive computer generated images on a non-transitory storage medium for playback in said image space.
