Apparatus and method for creating optical illusion effects
First Claim
1. A method of providing one or more selected visual illusion effects for live performances comprising:
- (a) providing an apparatus comprising;
(i) a first projection screen having a front viewing side and being positioned in a first plane;
(ii) a viewing area from which said first projection screen is visible to persons in an audience in said viewing area;
(iii) a stage area between said viewing area and said first projection screen;
(iv) an inclined, partially silvered mirror between said viewing area and said stage area, said mirror being inclined upward away from the viewing area;
(v) a movable second projection screen lying in a second plane at an angle to said first plane, wherein said inclined mirror is positioned between said planes and at equal angles to said first plane and said second plane;
(vi) a rear projection means for projecting images on said first projection screen so that images on said first projection screen are visible to viewers in said audience in said viewing area;
(vii) a second projection means for projecting images on said second projection screen so that images on said second projection screen are visible to said viewers by means of reflection from said mirror and appear to be located at a selected location; and
(viii) a computerized switching means of changing between images from said projection means;
(b) placing an object between said partially silvered mirror and said first screen;
(c) utilizing said projection means and said movable second projection screen to create a visual illusion wherein when images from said second projection means are reflected from said mirror so that said selected location is (i) in said first plane, said images are indistinguishable to said persons from images being projected directly on said first projection screen, (ii) in front of said first plane, said images appear to said persons to have moved closer to said audience than said first plane, and (iii) behind said first plane, said images appear to have moved farther from said audience than said first plane; and
(d) providing a character in a production utilizing said apparatus with a position sensor device to coordinate selected projected images with movement of said character.

Abstract
An apparatus for providing optical illusion effects, which includes a first projection screen; an area from which persons may view the first projection screen; a stage area between the viewing area and the first projection screen; an illumination system for the stage area so that objects on the stage may be illuminated at a desired light level without directly illuminating the first screen; an inclined, partially silvered mirror between the viewing area and the stage area; a second projection screen positioned in a second plane at a first angle to the first plane, wherein the inclined mirror is positioned between the first and second planes; a first projector for projecting images on the first projection screen so that images on the first projection screen may be seen by viewers in the viewing area; a second projector for projecting images on the second projection screen so that images on the second projection screen are visible to the viewers by means of reflection from the mirror and appear to be located at a selected location; and a component for changing between images from the projector so that viewers may be presented an image from either or both projector at any one time. Methods of using the apparatus include providing the optical illusion of having characters and objects merge interactively with projected images.

4. A method of achieving visual merger of stage and screen images, comprising:
-
(a) providing a viewing area for positioning viewers in an audience to view a live stage production, a stage area and a rear projection screen visible from said viewing area, a second projection screen not visible from said viewing area, stage lighting means, a partially silvered mirror between said viewing area and said projection screen, a rear projection means for projecting an image on said rear projection screen and a second projection means for projecting an image on said second projection screen so that the image is reflected from said mirror, wherein viewers in said viewing area cannot tell whether images being viewed are being reflected on said mirror or being projected on said rear projection screen; (b) providing moving picture images, which are visible to viewers in the viewing area, utilizing either of the projection means; and (c) providing a position sensor device, so that an object or person on the stage area appears to said viewers to change between being included among the moving picture images, being transparent to a chosen degree, being invisible, being on the stage separate from the moving picture images, and interacting with the moving picture images, through coordination of the degree of transparency of the object or person with the appearance and disappearance of images in the moving picture, by coordinated selective use of said projection means, said position sensor device, and said lighting means. - View Dependent Claims (5, 6)

7. A method of providing one or more selected visual illusion effects for live performances, comprising:
-
(a) providing an apparatus comprising; (i) a first projection screen having a front viewing side and being positioned in a first plane; (ii) a viewing area from which said first projection screen is visible to persons in an audience in said viewing area; (iii) a stage area between said viewing area and said first projection screen; (iv) an inclined, partially silvered mirror between said viewing area and said stage area, said mirror being inclined upward away from the viewing area; (v) a movable second projection screen lying in a second plane at an angle to said first plane, wherein said inclined mirror is positioned between said planes and at equal angles to said first plane and said second plane; (vi) a rear projection means for projecting images on said first projection screen so that images on said first projection screen are visible to viewers in said audience in said viewing area; (vii) a second projection means for projecting images on said second projection screen so that images on said second projection screen are visible to said viewers by means of reflection from said mirror and appear to be located at a selected location; and (viii) a computerized switching means of changing between images from said projection means; (b) placing an object between said partially silvered mirror and said first screen; (c) utilizing said projection means and said movable second projection screen to create a visual illusion wherein when images from said second projection means are reflected from said mirror so that said selected location is (i) in said first plane, said images are indistinguishable to said persons from images being projected directly on said first projection screen, (ii) in front of said first plane, said images appear to said persons to have moved closer to said audience than said first plane, and (iii) behind said first plane, said images appear to have moved farther from said audience than said first plane; and (d) providing a position sensor, and utilizing said position sensor in coordination with said projection means and said moveable second projection screen.
