A video communication system uses a light field display to present a holographic image of a remote scene (e.g., a hologram of a remote participant). The system may include a local light field display assembly and a controller. The controller generates display instructions based on visual data corresponding to a remote scene received from a remote image capture system (e.g., a remote light field display system). The display instructions cause the local light field display assembly to generate a holographic image of the remote scene.

An airborne acoustic vector sensor for simultaneously measuring triaxial particle acceleration in three dimensions and pressure includes a triaxial MEMS accelerometer sensitive to an Earth gravitational field. The airborne acoustic vector sensor includes one or multiple MEMS microphones sensitive to sound pressure and overlapping the accelerometer in frequency. The airborne acoustic vector sensor includes a solid body having a density approximating a density of air. The accelerometer is mounted in or upon the solid body. The airborne acoustic vector sensor includes a suspension system supporting the accelerometer and solid body within a framework.

A light filed (LF) display system for displaying holographic content to viewers in an amusement park (e.g., as part of an amusement park ride). The LF display system in an amusement park includes LF display modules tiled together to form an array of LF modules. In some embodiments, the LF display system includes a tracking system and/or a viewer profiling module. The tracking system and viewer profiling module can monitor and store characteristics of viewers on the amusement park ride, a viewer profile describing a viewer, and/or responses of viewers to the holographic content during the amusement park ride. The holographic content created for display on an amusement park ride can be based on any of the monitored or stored information.

According to various embodiments, systems and methods for transmitting acoustic waves in a region aided by reflection from environmental objects. An arrangement of acoustically reflective surfaces in an environment of a target can be detected to generate an environmental acoustic propagation channel model. An acoustic radiation pattern for reflecting one or more acoustic waves off of one or more acoustically reflective surfaces in the arrangement of acoustically reflective surfaces towards the target can be identified. A coherent acoustic beamforming device can be controlled to perform coherent beamforming of an acoustic hologram based on the acoustic radiation pattern to generate the one or more acoustic waves for reflection towards the target off of the one or more acoustically reflective surfaces.

A projection apparatus projects holographic images. The projection apparatus includes, within a housing, a laser projection system that outputs a laser beam, a diffuser to diffuse the laser beam projected by the laser projection system, a beam diverter/splitter that polarizes the received beam after it has been diffused by the diffuser, and a concave mirror onto which the beam is diverted and which reflects the images to the floating display position that is outside the housing. The apparatus may further include an adjustable lens to adjust the focus and/or size of images that are reflected from the concave mirror. Multiple projection apparatuses may be mounted around the floating display position to synchronously project the holographic images. A conical mirror may be used with the projection apparatus or with multiple projection apparatuses to display the images at a position above the conical mirror.

A light field (LF) display system for displaying holographic content (e.g., a holographic sporting event or holographic content to augment a holographic sporting event) to viewers in an arena. The LF display system in the arena includes LF display modules tiled together to form an array of LF modules. The array of LF modules create a holographic object volume for displaying the holographic content in the arena. The array of LF modules displays the holographic content to viewers in the viewing volumes. The LF display system can be included in a LF sporting event network. The LF sporting event network allows holographic content to be created at one location and presented at another location. The LF sporting event network includes a network system to manage the digital rights of the holographic sporting event content.

A holographic reality system and multiview display monitor a user position and provide virtual haptic feedback to the user. The holographic reality system includes a multiview display configured to display a multiview image, a position sensor configured to monitor the user position, and a virtual haptic feedback unit configured to provide the virtual haptic feedback. An extent of the virtual haptic feedback corresponds to an extent of a virtual control within the multiview image. The holographic reality multiview display includes an array of multiview pixels configured to provide different views of the multiview image by modulating directional light beams having directions corresponding to the different views and an array of multibeam elements configured to provide the directional light beams to corresponding multiview pixels.

Navigation applications may utilize various input data to determine various navigation routes. One example method of operating may include providing at least one navigation instruction to a navigation device via a navigation application, detecting the at least one instruction via a detection application, obtaining an image of a physical object, performing a holo-acoustic object manipulation of the physical object, and providing a visual display of the holo-acoustic manipulation as an additional navigation instruction.
