This invention describes a device that projects a 3D image into open space, viewable from different angles without special glasses. It works by using an array of tiny projectors in conjunction with a mirror system and a target object to create a digital form that appears to float in the air. The claims narrow the invention to a system specifically using a target object and mirror assembly with one or several projectors, and an array of micro-projectors.
Why it matters: Since 2014, advancements in micro-LED and pico-projector technology have significantly improved resolution and reduced cost. Progress in computational optics and real-time 3D rendering makes complex spatial projection more feasible.
