10116914 · 2018-10-30 · ·

A stereoscopic display system includes an image display panel, viewpoint position sensors, and a means to create first or left and second or right stereoscopic images corrected for parallax. This allows for multiple viewpoints to perceive the viewed 3D stereoscopic image as approximately fixed in space. In one embodiment, the first and second images may be perceived as a 3D stereoscopic image by applying shutter glasses. In another embodiment, the first and second images may be perceived as a 3D auto stereoscopic image by applying configurable louvers or light guiding layers. In this embodiment, the display system utilizes information from the position sensors to optimize electronically configurable louvers. This allows for large displays to be seen from multiple viewpoints. The virtual 3D stereoscopic object images, being virtually fixed in space may be interacted with by the user or users in much the same way 2D objects are manipulated by applying a touch screen. This allows for input systems such as virtual keyboards and remote controllers. The methods described may be applied in other ways, including, but not limited to gaming systems, 3D virtual caves, and simulators.

QUAD VIEW DISPLAY SYSTEM
20180278921 · 2018-09-27 · ·

Embodiments allow different viewers of a shared display to see different images. Images may have different combinations of polarization and time slices that correspond to filters in glasses worn by the viewers. The images viewed by each of the glasses may be based on the tracked position and orientation of the glasses, so that the images correspond to the user's viewpoint. Different images may be presented to left and right eyes for 3D stereoscopic viewing. The lenses of the glasses may have a filter that selects light of a specific polarization combined with a shutter that passes images during a specific time slice. The polarization filter may select circularly polarized images of a desired orientation and emit linearly polarized images. The shutter may use liquid crystals to twist the linearly polarized images during the desired time slice so that a final linear polarizer passes the image to the viewer.

Systems and methods provide for providing a stereoscopic six-degree of freedom viewing experience with a monoscopic 360-degree video are provided. A monoscopic 360-degree video of a subject scene can be preprocessed by analyzing each frame to recover a three-dimensional geometric representation of the subject scene, and further recover a camera motion path that includes various parameters associated with the camera, such as orientation, translational movement, and the like, as evidenced by the recording. Utilizing the recovered three-dimensional geometric representation of the subject scene and recovered camera motion path, a dense three-dimensional geometric representation of the subject scene is generated utilizing random assignment and propagation operations. Once preprocessing is complete, the processed video can be provided for stereoscopic display via a device, such as a head-mounted display. As user motion data is detected and received, novel viewpoints can be stereoscopically synthesized for presentation to the user in real time, so as to provide an immersive virtual reality experience to the user based on the original monoscopic 360-degree video and the user's detected movement(s).

Directionally illuminated waveguide arrangement

Disclosed is a light guiding valve apparatus comprising an optical valve, a two dimensional light source array and a focusing optic for providing large area collimated illumination from localized light sources. A stepped waveguide may be a stepped structure, in which the steps may be extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. A two dimensional array of viewing windows may be produced. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays with wide viewing freedom and low cross talk and near-eye displays that are substantially transparent.

A stereoscopic display method or system includes an image display panel, object tracking sensors, and a means to create first or left, and second or right stereoscopic images based upon viewpoint location. This allows the user to perceive the viewed 3D stereoscopic image as approximately fixed in space. A first embodiment employs differently filtered colored, stereoscopic images. The first and second differently filtered colored images may be perceived as a 3D stereoscopic image by applying anaglyph glasses. In a second embodiment the method of passively polarized glasses may be applied with the result being a stereoscopic image whose location is approximately fixed in space. A third embodiment employs passively polarized anaglyph glasses. This provides the advantage of allowing two different viewers to see different virtual 3D stereoscopic images whose location remains approximately fixed in space. By employing tracking sensors, user gesturing or pointing may now allow interaction with the virtual 3D stereoscopic images in much the same way 2D objects are manipulated by employing a touch screen. This may be combined with voice commands. This allows for input systems such as virtual 3D touch panels, keyboards and remote controllers.
