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.

Aspects of the subject disclosure may include, for example, obtaining a first request for a first virtual object, obtaining first data regarding the first virtual object responsive to the obtaining of the first request, analyzing the first data to identify a first plurality of characteristics for the first virtual object, wherein the first plurality of characteristics include a first visual aspect of the first virtual object, a first auditory aspect of the first virtual object, a first scent aspect of the first virtual object, and a first haptic aspect of the first virtual object, and responsive to the analyzing of the first data, enabling at least a first sensory unit of a plurality of sensory units to render the first virtual object in accordance with the first plurality of characteristics. Other embodiments are disclosed.

The present invention discloses devices for projecting holographic content from a watch and methods therein. Devices include: a watch base for housing the watch; an opaque watch face attached to the base; a transparent watch cover for protecting the face; a light wand having a series of controllable light-emitting elements configured to project the holographic content, wherein the series is disposed on the wand such that light emitted from the elements is projected primarily toward the cover, the wand is disposed: mostly parallel to the surfaces of the face and cover; and between the face and cover with a spacing greater than about 40% of a face/cover gap adapted to produce suitable, projected holographic content free from distortion caused by the proximity of the face to the wand; and a spinning axis for mounting the wand, configured for rotating in order to spin the wand for projecting the holographic content.

The interactive holographic human-computer interface (H2CI) includes a local system in communication with an external system, and a holographic display unit for constructing and displaying one or more holograms. The one or more holograms emits electromagnetic radiation. The interface further includes a motion detector for detecting motion, type of motion, dwell time, and location of a physical command object relative to the displayed hologram, and sensors on the external system to determine the location of two or more physical objects relative to each other. Emission and detection by the one or more displayed holograms of electromagnetic radiation is used to simulate electrical, vibration, or other physical phenomena characteristic of the physical objects represented by the one or more displayed holograms. The emitted electromagnetic radiation is converted into a command signal when the electromagnetic radiation is detected by another hologram.

The distance dedicated teaching system includes a data acquisition module, a data transmission module, a 5G cloud rendering module, a natural interaction module, a holographic display module and a teaching service module.

A control device of a display and operating device specifies a graphical configuration of a display element to be displayed by the display device. Based on the specified graphical configuration, at least one light wave parameter for a respective light wave of a group of light waves is ascertained. A totality of the light wave parameters describes an interference pattern which describes an at least partial superposition of the light waves for generating an image representation of the display element. An interference pattern signal which describes the totality of the ascertained light wave parameters is generated and the generated interference pattern signal is transferred to an interference output device of the display and operating device. Based on the transferred interference pattern signal, the interference output device generates a light wave interference, and an output of a real image of the display element is displayed.

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.

Aspects of the present invention provide an approach for authentication of a user of a computer system by displaying holographic objects in a bounded field of view of a user, identifying movement of the user interacting with the holographic objects, comparing the interacting movement to authentication information linking user authentication to a movement defined within confidence limits, and when the identified user movement indicates the user interacted with the displayed holographic objects within the defined confidence limits, authenticating the user on the computer system.

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.
