Near-eye displays project images directly into a viewer\'s eye, encompassing both head-mounted displays (HMDs) and electronic viewfinders. Such displays confront a fundamental problem: the unaided human eye cannot accommodate (focus) on objects placed in close proximity. This talk introduces a light-field-based approach to near-eye display that allows for dramatically thinner and lighter HMDs capable of depicting accurate accommodation, convergence, and binocular-disparity depth cues. Such 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. Building on related integral imaging displays and microlens-based light-field cameras, we 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 talk will conclude with a demonstration featuring a binocular OLED-based prototype and a GPU-accelerated stereoscopic light field renderer.
Douglas Lanman works in the Computer Graphics and New User Experiences groups within NVIDIA Research. His research is focused on computational imaging and display systems, including head-mounted displays (HMDs), automultiscopic (glasses-free) 3D displays, light field cameras, and active illumination for 3D reconstruction. He received a B.S. in Applied Physics with Honors from Caltech in 2002 and M.S. and Ph.D. degrees in Electrical Engineering from Brown University in 2006 and 2010, respectively. Prior to joining NVIDIA, he was a Postdoctoral Associate at the MIT Media Lab from 2010 to 2012 and an Assistant Research Staff Member at MIT Lincoln Laboratory from 2002 to 2005. Douglas has worked as an intern at Intel, Los Alamos National Laboratory, INRIA Rhône-Alpes, Mitsubishi Electric Research Laboratories (MERL), and the MIT Media Lab. He presented the \"Build Your Own 3D Scanner\" course at SIGGRAPH 2009 and SIGGRAPH Asia 2009, the \"Build Your Own 3D Display\" course at SIGGRAPH 2010, SIGGRAPH 2011, and SIGGRAPH Asia 2010, and the \"Computational Imaging\" and \"Computational Displays\" courses at SIGGRAPH 2012.
