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.

Claim (Index 1):
A method comprising:\n segmenting a virtual scene into a set of focal surfaces based on scene geometry data for the virtual scene, the scene geometry data identifying depths for one or more objects in the virtual scene; adjusting, for a focal surface from the set of focal surfaces, a shape of the focal surface that minimizes a distance between the focal surface and one or more nearest objects in the virtual scene to the focal surface; and generating, for the focal surface, a phase function for a spatial light modulator (SLM) to adjust a wavefront of light of the virtual scene, the phase function when applied by the SLM introduces phase delays in the wavefront that reproduces a focal pattern corresponding to the adjusted shape of the focal surface.
