A floating three-dimensional image display system is provided. The floating three-dimensional image display system includes a controller and a first floating image display device. The controller converts a plurality of image information of an electronic device into a plurality of first floating image information according to the plurality of image information and a plurality of depth information of the electronic device, and displays the plurality of first floating image information in a space above a first side of the first floating image display device through the first floating image display device.

Some implementations of the disclosure are directed to tessellating a light field into a size or depth that is larger or further extended than the pupil size of an imaging system or display system. In some implementations, a display system comprises: a display configured to emit light corresponding to an image; a first optical component positioned in front of the display, the first optical component configured to pass the light to an orthogonal field evolving cavity (OFEC) at a plurality of different angles; the OFEC, wherein the OFEC comprises a plurality of reflectors that are configured to reflect the light passed at the plurality of different angles to tessellate the size of the image to form a tessellated image; and a second optical component optically coupled to the OFEC, the second optical component configured to relay the tessellated image through an exit pupil of the display system.

An interactive method using a floating image display and a system thereof are provided. The method is performed in the display apparatus. The display apparatus links to a computer system that executes a driver for establishing a communication interface there-between. In the method, the display apparatus receives image data from the computer system and floating image data can be obtained therefrom. The floating image display apparatus displays a floating image via a display panel after a conversion process. After that, a user can manipulate directly on the floating image by gesture. A procedure running in the display apparatus can determine an interactive instruction according to variations of three-dimensional coordinates. When the interactive instruction is transmitted to the computer system, a new image data is formed in response to the interactive instruction. The display apparatus then displays a new floating image after receiving new data.

A device for providing a reverse pass-through view of a user of a headset display to an onlooker includes an eyepiece comprising an optical surface configured to provide an image to a user on a first side of the optical surface. The device also includes a first camera configured to collect an image of a portion of a face of the user reflected from the optical surface in a first field of view, a display adjacent to the optical surface and configured to project forward an image of the face of the user, and a screen configured to receive light from the display and provide the image of the face of the user to an onlooker.

The present disclosure relates to a method for calibrating a projector. In one example, the method includes receiving by a processing element light field data corresponding to a calibration image projected by a projector and captured by a light field capturing device, and modeling by a processing element one or more intrinsic properties of the projector using the light field data and the calibration image. The calibration image may be projected by the projector directly into the light field capturing device.

The disclosure describes various aspects of a partial light field display architecture. In an aspect, a light field display includes multiple picture elements (e.g., super-raxels), where each picture element includes a first portion having a first set of light emitting elements, where the first portion is configured to produce light outputs that contribute to at least one a two-dimensional (2D) view. Each picture element also includes a second portion including a second set of light emitting elements (e.g., sub-raxels) configured to produce light outputs (e.g., ray elements) that contribute to at least one three-dimensional (3D) view. The light field display also includes electronic means configured to drive the first set of light emitting elements and the second set of light emitting elements in each picture element. The light field display can also dynamically identify the first portion and the second portion and allocate light emitting elements accordingly.

Described are various embodiments of a light field vision testing device, adjusted pixel rendering method and computer-readable medium therefor, and vision testing system and method using same. In one embodiment, a device or computer-implemented method is provided to dynamically adjust user perception of an input image to be rendered via a set of digital display pixels and a corresponding array of light field shaping elements until an optimal visual acuity level is identified.

Systems and methods for auto-calibrating a virtual reality (VR) or augmented reality (AR) head-mounted display to a given user with a refractive condition without adding corrective lenses to optical elements of the head-mounted display and without requiring subjective refraction procedures. An autorefractor assembly of the head-mounted display, or a separate autorefractor headset, measures refractive error and communicates the measurements to a control system of the head-mounted display. Based on the refractive error measurements, the head-mounted display can adjust adaptive lenses and other adaptive optics to modify transmitted images; can make compensating adjustments to images displayed by a stereoscopic display device of the head-mounted display; or can make both types of adjustment. These automatic calibrations correct displayed images to compensate for refractive aberration in one or both eyes of the user. In an embodiment, the head-mounted display can correct other vision defects of the given user measured by objective ophthalmic examination.

A system and method for lightfield communication can be configured to receive one or more images, determine one or more features in the one or more images, and generate a lightfield image from the one or more images where at least one of the one or more features is in a focal plane of the lightfield image.
