There is provided a lighting system for a vehicle. The lighting system comprises a holographic projector and a light distribution system. The holographic projector comprises a hologram engine and a spatial light modulator. The hologram engine is arranged to output holograms. The spatial light modulator is arranged to display each hologram and spatially-modulate light in accordance with each hologram. The spatially-modulated light forms a holographic reconstruction, corresponding to each hologram, on a replay plane. The light distribution system comprises a plurality of optical fibres. Each optical fibre comprises an input optically-coupled to respective sub-area of the replay plane and an output optically coupled with an illumination sub-system of the vehicle.

Systems, methods, and computer-readable media are disclosed for representing a transfer of a digital object using holographic images. User input is received that is indicative of a selection of the digital object for transfer from a sending device to a receiving device. Spatial attribute data is generated based at least in part on at least one of a distance or a relative orientation between the sending device and the receiving device, and a transition path is determined based at least in part on the spatial attribute data. Holographic image data is then generated based at least in part on the transition path, and the holographic image data is sent to one or more holographic projectors to cause a first holographic image representative of the digital object and a second holographic image representative of the transition path to be projected.

A system and method for facilitating tracking of interactions with a plurality of content types within a digital reality. One or more users enter a public digital zone where content from one or more holographic applications is available for interaction through digital reality devices. Interactions include seeing, looking at, clicking on, engaging with, and immersing into the digital content from the one or more holographic applications. Potential outputs of these interactions include transactions, switching to other holographic applications, or completely exiting the holographic application. Each of these interactions is continuously tracked by a telemetry and tracking cloud server communicatively connected to a cloud server and holographic application. Cloud servers of each public digital zone connect to cloud servers of other public digital zones, enabling users to seamlessly access holographic applications located in other public digital zones.

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 computing device and method are provided for transmitting a relevant subset of map data, called a neighborhood, to enable mutual spatial understanding by multiple display devices around a target virtual location to display a shared hologram in the same exact location in the physical environment at the same moment in time. The computing device may comprise a processor, a memory operatively coupled to the processor, and an anchor transfer program stored in the memory and executed by the processor.

Example systems and methods perform streaming of volumetric media and accommodate high user interactivity. A device is configured to access and render streaming holograms and may implement a window as a buffer. In addition, a hologram streaming machine can be configured to stream full or partial holograms in the form of 3D blocks, where different 3D blocks represent a same portion of hologram but may have different resolutions depending on where the user is positioned and looking relative to each 3D block, thus saving network capacity by focusing on what the user is looking at. Since many 3D blocks may be empty much of the time, may be occluded or far away from the user's viewing position, or may be numerous within a 3D space, the device can be configured to request 3D blocks based on their utility, which may be calculated based on bitrate, visibility, or distance.

The present disclosure provides a conference device, a method of controlling the conference device, and a computer storage medium. The conference device includes a display, an image sensor, a holographic projector, and a controller configured to identify, by using an image data from the image sensor, a modification action performed at a target location for a holographic image projected by the holographic projector, modify holographic projection data based on the modification action, and convert modified holographic projection data into modified two-dimensional imaging data.

Methods, computing devices and display devices are disclosed for displaying virtual content at a target location that is determined relative to a shared anchor. Image data of a physical environment may be captured. A shared anchor tag may be identified in the image data. Based on identifying the shared anchor tag, shared anchor tag image data may be transmitted to a server. Based at least on data retrieved by the server, a data packet comprising a shared anchor associated with a second display device is received, wherein the shared anchor defines a three-dimensional location in the physical environment. A hologram is displayed at a target location determined relative to the location of the shared anchor.

Disclosed is a holographic display including a spatial light modulator (SLM) with pixels, the SLM pixels being on a substrate, the SLM including circuitry which is on the same substrate as the SLM pixels, the circuitry operable to perform calculations which provide an encoding of the SLM.
