Producing ultra-high-quality content is the next grand challenge for the VR industry. Creating a virtual reality that even the human eye cannot distinguish from the real world will require light-field technology--3D imaging technology that captures the light rays people perceive from different locations and directions. When combined with computer vision and machine learning, light-field technology provides a viable path for producing low-cost, high-quality VR content.
