PetaRay’s solution is called LiFiD, which is delivered in the form of optical module for near-eye displays. It reproduces the light rays of a sceneprojects them directly onto user’s retinas. Besides projecting light rays directly onto user’s retina to solve the vergence-accommodation conflict, LiFid has continuous focal planesallows the display content to precisely match the desired depth of field. No eye tracker and/or other sensors are needed for the projection.
