Abstract: This light-field-based approach to near-eye display allows for dramatically thinner and lighter head-mounted displays capable of depicting accurate accommodation, convergence, and binocular-disparity depth cues. The near-eye light-field displays depict sharp images from out-of-focus display elements by synthesizing light fields that correspond to virtual scenes located within the viewer's natural accommodation range. While sharing similarities with existing integral imaging displays and microlens-based light-field cameras, the displays optimize performance in the context of near-eye viewing. Near-eye light-field displays support continuous accommodation of the eye throughout a finite depth of field; as a result, binocular configurations provide a means to address the accommodation-convergence conflict that occurs with existing stereoscopic displays. This demonstration features a binocular prototype and a GPU-accelerated stereoscopic light field renderer.
