A light field (LF) display system implements a holographic video game. The LF display system includes an LF display assembly that displays holographic game content. The LF display system can also include a sensory feedback assembly that provides tactile feedback to users by projecting an ultrasonic wave, a tracking system that can track one or more body parts of a user, and a controller that executes a game application and generates display instructions for the LF display assembly. The LF display system can implement an interactive video game that tracks a body part of a player and provides both visual and haptic feedback to the player to depict an in-game interaction, such as an explosion or impact. The video game may be implemented as part of an LF gaming network.

The present disclosure concerns a light-field projection system, comprising a pin-light array generating an incident light-field illuminating an optical light modulator for modulating the incident light-field and projecting a plurality of modulated light-field components along a projection axis; a first optical element configured for forming first pin-light images in a first pin-light plane and modulator images in a modulator image plane; and a second optical element defining an eye-box region and for forming second pin-light images in a second pin-light plane within the eye-box; the first and second pin-light planes and the modulator image plane being substantially perpendicular to the projection axis; the system further comprising at least one optical device at the first pin-light plane and being configured for interacting with at least one of the modulated light-field components, spatially shifting the modulated light-field components in the modulator image plane. The light-field projection allows for foveated projection.

A light field near-eye display device and a method of light field near-eye display are provided. The light field near-eye display device includes a processor, a display panel, and a lens module. The processor adjusts a preset eye box according to a vision data to obtain an adjusted eye box, and adjusts a preset image data according to the adjusted eye box to generate an adjusted image data. The display panel is coupled to the processor and emits an image beam according to the adjusted image data. The lens module includes a micro lens array and is disposed between the display panel and a pupil. The image beam is incident on the pupil via the lens module and displays a light field image.

A system for determining refraction features of both first and second eyes of a subject including a light field display device, a system of localization of the positions of the first and second eyes of the subject, the light field display device generating a first light field directed selectively toward the first eye, and, respectively, a second light field directed selectively toward the second eye, control circuitry that adjusts the first light field as a function of at least a first refraction parameter associated with at least a first optical aberration for the first eye and the control circuitry adjusting said second light field as a function of at least a second refraction parameter associated with at least a second optical aberration for the second eye.

The present invention relates to the field of three-dimensional display technology, and more specifically, to a glasses-free light-field display method based on asymmetric light distribution of a projecting beam. In the method described in this patent application, beam projected by a pixel or a sub-pixel of a display device is guided to the corresponding pixel-viewing-zone or sub-pixel-viewing-zone of an asymmetric shape, by a corresponding modulation element. Based on these asymmetric pixel-viewing-zones or sub-pixel-viewing-zones, viewing zones for different pixel groups or sub-pixel groups are designed with different arrangement densities along different directions, to realize glasses-free light-field display with a reduced number of viewing zones. Time multiplexing is further introduced for presenting more viewing zones.

Each of the imaging modules includes a liquid crystal lens array and a display screen, the liquid crystal lens array is disposed on a light exit side of the display screen, and images of the plurality of imaging modules are parallel to each other.

Implementations of a compressive light field projection system are disclosed herein. In one embodiment, the compressive light field projection system utilizes a pair of light modulators, such as digital micromirror devices (DMDs), that interact to produce a light field. The light field is then projected via a projection lens onto a screen, which may be an angle expanding projection screen that includes a Fresnel lens for straightening the views of the light field and either a double lenticular array of Keplerian lens pairs or a single lenticular, for increasing the field of view. In addition, compression techniques are disclosed for generating patterns to place on the pair of light modulators so as to reduce the number of frames needed to recreate a light field.
