A projector system using a screen comprised of either a plurality of miniature, reflective, and concave or convex curved surfaces that are arranged in a pattern to create a screen surface for front projection, or a plurality of miniature, transparent, and curved convex or concave lenses that are arranged in a pattern to create a screen surface for rear projection, and a projector system with the pixel capacity to control the color and brightness focused onto many different subsections of each curved surface. Each curved lens or curved mirror surface is small enough so that when viewed from the viewing area, the lit and unlit areas seen within each individual curved surface blend together so that only the average brightness and color of each curved surface can be seen by a viewer. By controlling the subsections of each curved surface with focused light from a high resolution projector, the system can control the image the viewer sees in their left eye separately from their right eye and the viewer can see stereographic images without the need to wear filtering glasses. With inclusion of an external head tracking system, the left/right images for each subsection can be switched as needed when one or multiple viewers move their head or seating position within the viewing area. |

1. A projection system where viewers can see the same holographic image from different angles comprising:
a single projector or group of projectors that can focus pixels on a screen; a front projection screen, comprising a flat or curved projection surface, and that surface consisting of an array of reflective concave or convex curved mirrors, whereby each mirror on the screen surface is individually oriented to reflect projector light off of its curved surface and towards the center of the same area where viewers are best located, and when requirements for mirror rotation are more than the overall reflective shape of the screen allows, each individual mirror is rotated to meet the requirements, but it is positioned to be as close too, but not extend beyond an imaginary shape that is the same shape as the desired screen shape and the edges between mirrors are cut to be parallel with the incoming light at each edge position; a multi-user eye tracking system that provides real-time data on viewer eye position and any data read from the projector or group of projectors that may help with synchronization or alignment, to microprocessors that are operated by software that can be built inside the projector or group of projectors, to drive their device imagers, or alternatively the data can be provided to an external computer connected to and operating the device imagers of a single projector, or group of projectors, and the external computer would be operated by software; |
