Patent Images

1. A method of using projected imagery in which some objects in the imagery are moving laterally, which when said imagery is projected through a polarizing projection filter and observed through polarizing viewing glasses, provides visual depth effects, the method comprising:

  • using viewing glasses comprising a light polarizing means for transmitting light to an observer'"'"'s left eye and a light polarizing means for transmitting light to the observer'"'"'s right eye, and the plane of polarization of said light polarizing means for the right eye having an angular offset of 90 degrees from the plane of polarization of said light polarizing means for the left eye;

    orienting the plane of polarization of the polarizing projection filter with less angular offset from the plane of polarization of the light transmitting means for the left eye than to the plane of polarization of the light transmitting means for the right eye, and selecting objects which move from left to right from the observer'"'"'s perspective to create the perception that the objects are closer to the observer, and selecting objects which move from right to left to create the perception that the objects are farther away from the observer; and

    orienting the plane of polarization of the polarizing projection filter with less angular offset from the plane of polarization of the light transmitting means for the right eye than to the plane of polarization of the light transmitting means for the left eye, and selecting objects which move from left to right from the observer'"'"'s perspective to create the perception that the objects are farther away from the observer, and selecting objects which move from right to left to create the perception that the objects are closer to the observer.
