Problems solved by technology

[0007] Conventional stereoscopic displays provide binocular parallax, which supports convergence at any point, but only allows the viewer to accommodate on the display surface and thus suffers from an accommodation-convergence conflict

Embodiment Construction

[0082] Various embodiments of the invention relate to methods, systems, and articles of manufacture for displaying stereoscopic vision for virtual and / or augmented reality employing free-form optics with addressable focus in a single embodiment or a number of embodiments. Other objects, features and advantages of the invention are described in the detailed description, drawings and claims.

[0083] A method and system for visual display is disclosed that is well suited for virtual and augmented reality applications, as well as other applications such as near-eye displays, computing and display applications, or even text-only displays. Some embodiments relate to systems for displaying stereoscopic vision for virtual and / or augmented reality employing free-form optics with addressable focus. In some embodiments, the system may include an image source that injects light directly (without intervening elements) or indirectly (with one or more intervening elements) into one or more ...

Abstract

Several unique hardware configurations and methods for freeform optical display systems are disclosed. A freeform display system includes primary freeform optical element(s) and secondary freeform optical element(s) in tiled arrangements to expand the horizontal field of view (FOV) or the vertical field of view. The system may include a variable focusing system that produces intermediate pupil and changes the focal distance of a single focal plane or switches among multiple focal planes for rendering objects in focus while resolving accommodation-convergence conflict. The system may map light samples to appropriate light rays in physical space and use a cluster of projectors to project the mapped light rays to produce the light field of the virtual display content. Methods for making tiled freeform optical display systems and methods for producing virtual content with variable focus freeform optics and rendering light fields are also disclosed.
