Abstract
A system creating an autostereoscopic augmented reality (AR), virtual reality (VR), or other visual display experience involving 3D images, presented to a viewer without glasses or other head-gear. The system includes a projection screen, which includes a reflective surface formed using retroreflective material. The system includes a projection assembly and a beamsplitter, which is disposed between an outlet of the projection assembly and the projection screen. The system includes a physical scenic space facing a lower side of the beamsplitter and a viewing space facing an upper side of the beamsplitter. A controller operates the projector assembly to project left and right eye images toward the projection screen. The left and right eye images are then directed to left and right eye positions so a viewer with eyes positioned at the left and right eye positions perceives a virtual object concurrently with light from the physical scenic space.
