A light field (LF) display system presents holographic content to one or more viewers in a public setting for digital signage applications. In some embodiments, the LF display system includes a sensory feedback assembly, a tracking system and/or a viewer profiling module. The sensory feedback assembly may comprise sensory feedback devices that provide sensory feedback to viewers of the LF display system in tandem with the presented holographic content. The tracking system may comprise cameras used to track the viewers of the LF display system. Based on a viewer's tracked position and/or tracked gaze, the LF display system may generate holographic content that is perceivable by certain viewers but not viewable by others. The viewer profiling module may identify each viewer for providing personalized holographic content and may further monitor and record behavior of viewers for informing subsequent presentations of holographic content by the LF display system.

The present disclosure provides a holographic reproduction device, a holographic reproduction system, and a holographic display system. The holographic reproduction device includes a first light source configured to provide first coherent light; at least one electrically addressed liquid crystal display panel configured to display a holographic interferogram, so that the first coherent light is diffracted when the first coherent light transmits through the holographic interferogram to present a holographic reproduction image. A liquid crystal material of the electrically addressed liquid crystal display panel includes smectic liquid crystal.

A vehicle mountable holographic promoting system and method of use; the vehicle mountable holographic promoting system includes a body with at least one light, a mount, and a controller in communication with a software application and the body. The body is mountable to the vehicle via the mount. The mount is able to be removably attachable or otherwise secured to roof of a vehicle. The controller controls the body such that the body is able to visually promote via an image display at least one promotable item using the at least one light. The promotable item appearing to float on a plane above the vehicle.

Vehicle mountable holographic promoting system and method of use; system includes a body with light, mount, and controller in communication with a software application and the body. The body is mountable to the vehicle using mount. Mount can be removably attachable or otherwise secured to the roof of the vehicle. The controller controls the body such that the body can visually promote via an image display an item using the light-display region appearing to float on a plane above vehicle.

A light field (LF) display system comprises a LF display assembly. The LF display assembly comprises one or more LF display modules and is configured to present holographic merchandise to a patron in a viewing volume of the LF display system with the LF display modules. The LF display system is also configured to receive patron input in response to presentation of the holographic merchandise. The LF display system may track patron movement within the viewing volume of the LF display system. The LF display system may update presentation of the holographic merchandise based on the received patron input and/or the tracked patron movement. The LF display system may further provide other sensory feedback via a sensory feedback system. The LF display system may further comprise a patron profiling system for storing information for a patron under a patron profile. The LF display system may further present information via a holographic assistant presented by the LF display modules.

A method of coordinating a mixed-reality (MR) configured head-mounted display (HMD) with a separate media device to enable a synchronized user experience. The method includes establishing a communication channel between the HMD and the media device. At least one of the following is performed via the communication channel: accessing content on the media device or executing control commands on the media device based on an interface displayed by the HMD, or detecting media content presented by the media device and synchronizing display of MR content on the HMD and the detected media content.

A vehicle display system is able to integrate with a license plate holder and replace a license plate to digitally display a name, phrase, logo, or other image. A series of light-emitting diodes may be arrayed across a plate and may be in communication with a digital controller. The controller and the diodes may be powered by the vehicle's electrical systems and may communicate wireless with an external device. In this way, the controller may cause the diodes to display an image which may be energized, deenergized, and customized by the user utilizing the external device. The diodes are encased by a thick lens which draws out the image of the lighted diodes into a three-dimensional hologram, providing depth and visibility to the image.

A vehicle wheel assembly includes a wheel. A tire is disposed around the wheel. A wheel cap is coupled to the wheel and includes a polymeric base. A substantially transparent cap is positioned on the base which defines a first surface and a second surface. The second surface integrally defines an optical grating.

A poster board whose central region is thicker than its peripheral region. The peripheral region having a reflective and refractive surface that provides iridescent color hues within a rainbow spectrum. The reflective and refractive surface may contain a holographic pattern of geometric shapes of different sizes and shapes. The reflective and refractive surface may give rise to spaced apart bands with each of the bands containing the rainbow spectrum of color hues.

A volumetric display system including a volumetric display for displaying a scene viewable as a three-dimensional floating-in-the-air scene in a display space, enabling a user to reach a first object into the display space, a location determination unit locating real objects in the display space, providing a location of the first object when the first object is inserted into the display space, and a computer for receiving the location of the first object, detecting when the location of the first object is at a location where an object is displayed in the three-dimensional scene, thereby determining that the first object is viewable as touching the displayed object following a detection of the first object viewable as touching the displayed object, producing a new three-dimensional scene displaying the displayed object as if manipulated by the first object. Related apparatus and methods are also described.
