SYSTEM AND METHOD FOR PRESENTING IMAGE CONTENT ON MULTIPLE DEPTH PLANES BY PROVIDING MULTIPLE INTRA-PUPIL PARALLAX VIEWS

An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity. Advantageously, the wavefront divergence, and the accommodation cue provided to the eye of the user, may be varied by appropriate selection of parallax disparity, which may be set by selecting the amount of spatial separation between the locations of light output.

Multi-perspective stereoscopy from light fields

Methods and systems for generating stereoscopic content with granular control over binocular disparity based on multi-perspective imaging from representations of light fields are provided. The stereoscopic content is computed as piecewise continuous cuts through a representation of a light field, minimizing an energy reflecting prescribed parameters such as depth budget, maximum binocular disparity gradient, desired stereoscopic baseline. The methods and systems may be used for efficient and flexible stereoscopic post-processing, such as reducing excessive binocular disparity while preserving perceived depth or retargeting of already captured scenes to various view settings. Moreover, such methods and systems are highly useful for content creation in the context of multi-view autostereoscopic displays and provide a novel conceptual approach to stereoscopic image processing and post-production.

Interest-attention feedback method for separating cognitive awareness into different left and right sensor displays
09805612 · 2017-10-31 · ·

A method for using an interest-attention feedback loop involving the determination of the interest of a person in a left sensor stimulation stream and a right sensor stimulation stream, and the adjustment of attention factors to balance that interest, with the intent to facilitate, or train, a person to intentionally suppress binocular fusion and operate within the dual experience, where the person is able to simultaneously render separate left and right mental displays. The dual experience allows the person new mental processing capabilities that can produce novel information synthesis, double the information input in man machine interfaces, and allow reaction to the cognitive awareness of two simultaneous world views. This includes facilitating awareness and interactions with two different computer screen interfaces simultaneously, reducing fatigue associated with optical screen switching, and encouraging the fusion of two different simultaneous experiences into an abstract information synthesis.

NEAR-EYE DISPLAY MODULE, I-TYPE COMPOSITE DISPLAY MODULE, II-TYPE COMPOSITE DISPLAY MODULE, AND III-TYPE COMPOSITE DISPLAY MODULE BASED ON PIXEL-BLOCK-APERTURE STRUCTURES
20220311993 · 2022-09-29 · ·

The invention discloses a near-eye display module based on pixel-block-aperture structures, which includes more than one pixel-block-aperture structures. The divergence angle and propagation direction of the light beam from a pixel is specially modulated, and the light beams from pixels of adjacent pixel-block-aperture structures are endowed with different orthogonal characteristics, to guarantee the light beam from a pixel transmitting to the viewer's pupil only through corresponding aperture(s) for Maxwellian View or one-pupil-multi-view display. The arrangement of multiple pixel-block-aperture structures makes a large field of view (FOV) realizable, and the orthogonal-characteristics design can suppress the crosstalk between adjacent pixel-block-aperture structures effectively.

Beam combining for highlight projection

A novel projection system includes first and second light sources (e.g., sets of lasers), a spatial light modulator (SLM) that receives light from the first light source, and a beam steering device that receives light from the second light source and steers the light to highlight regions of the SLM. The SLM then modulates the light from both light sources to generate a highlighted imaging beam which can then be projected on a viewing surface. The highlighted imaging beam can represent a highlighted 2D image or a highlighted left- or right-eye view of a 3D image. The projection system thus improves peak brightness in the displayed highlighted images without incorporating a separate highlight projector or other expensive equipment. Methods for highlighting projected images are also described.
