  • Patent number: 11106276
    Abstract: A virtual reality (VR) headset adjusts the phase of light of a virtual scene received from a display element using a spatial light modulator (SLM) to accommodate changes in vergence for a user viewing objects in the virtual scene. The VR headset receives virtual scene data that includes depth information for components of the virtual scene and the SLM adjusts a wavefront of the light of the virtual scene by generating a phase function that adjusts the light of the virtual scene with phase delays based the depth values. Individual phase delays shift components of the virtual scene based on the depth values to a target focal plane to accommodate a user at a vergence depth for a frame of the virtual scene. Further, the SLM can provide optical defocus by shifting components of the virtual scene with the phase delays for depth of field blur.

  • Patent number: 10558049
    Abstract: A head mounted display (HMD) adjusts the phase of light of a virtual scene using a spatially programmable focusing element. Depths of the virtual scene are approximated to one or more focal surfaces and the shape of the focal surfaces is then adjusted to minimize the distance of the focal surface to features in the virtual scene. The resulting shape of the focal surface is a continuous piecewise smooth three-dimensional curve. A phase function is generated for each focal surface that, when executed by the spatially programmable focusing element, reproduces a focal pattern corresponding to the each focal surface, which bends and shapes the wavefront to produce a focal pattern that conforms to the scene geometry.
