ABSTRACT:
This invention is a three-dimensional display apparatus that has the electromechanical ability to form a display into a relief of a video image. The physical formation of the display updates about 1/24th of a second for real time motion in sync with the video image. The displayed relief image is shown in true three-dimensional space that a user sees and feels. This is accomplished by a plurality of optic fiber bundles that have distal ends and proximal ends, the distal ends radiate outwardly from an image projector carrying a light image. An optic fiber adjustment assembly controllably moves the distal ends of the optic fibers away from and toward the image projector thus forming a moving three-dimensional relief image. A sensor determines the position of each of the distal ends of the optic fibers and then sends the position information to a computer. As the images shown by the projector change, a lookup table tells the computer to signal the optic fibers and move them in sync with the new projected images. Thus, as the optic fibers are adjusted, a new corresponding three-dimensional relief image is formed. The same computer controlled assemblies that extend and contract the optic fibers may be also used to detect and react to the user's touch through the sensors that monitor the position of the optic fiber bundles.
