Just when you thought there was only one big player in the modern HMD space, it’s becoming clear that we are indeed moving towards a diversified market. Nvidia has revealed details of a new HMD prototype they are developing that is based on a light field display. In addition to being a lot more compact than what has been previously marketed, sharp images are depicted from out-of-focus elements by synthesizing light fields corresponding to virtual objects within a viewer’s natural accommodation range.
Think of it as a series of adjustments that compensate according to what is being digitally looked at so you always have a crisp image in 3D form without the discomfort of accommodation-convergence conflict (i.e. a conflict between your eyes, the physical screen, and the depth your eyes are perceiving). The above video and attached paper give a clearer description.
