Implementations of various computer methods to couple a computerized ball device which acts as a mobile computing device to record the users environment and project light towards waveguide eyeglasses or contacts which then allows a user to view imbedded light structure holograms in the waveguide while viewing the actual world. The computer ball device additionally has the ability to be docked in a drone cradle which creates a database map of the user's environment while not being utilized by the user for an immediate task. The device may also attach to a wrist band for mobility. The device also has the ability to couple the projected light structures so that a plurality of users may view the same light structure content to build an environment of trust. The device decouples the traditional design of head mounted virtual and mixed reality that place together the camera with the head mounted device.

Projection control method, electronic device, and storage medium are provided. The projection control method includes obtaining a first depth data corresponding to a reference object; obtaining a second depth data corresponding to a remote object; determining a first scaling ratio corresponding to the remote object according to the first depth data and the second depth data; and performing a holographic projection on the remote object according to the first scaling ratio and the second depth data, to obtain a first projection image.

A plurality of control points (10) are defined which each have a known spatial relationship relative to an array of transducers. An amplitude is assigned to each control point (12). A matrix (16) is produced containing elements which represent, for each of the control points, the effect that producing a modeled acoustic field having the assigned amplitude with a particular phase at the control point has on the consequential amplitude and phase of the modeled acoustic field at the other control points (14). Eigenvectors of the matrix (18) are determined, each eigenvector representing a set of phases and relative amplitudes of the modeled acoustic field at the control points. One of the sets (20) is selected and the transducer array is operated to cause one or more of the transducers to output an acoustic wave each having an initial amplitude and phase such that the phases and amplitudes of the resultant acoustic field at the control points correspond to the phases and relative amplitudes of the selected set (22, 24).

An image display method includes: obtaining an input operation by a first user on a virtual interactive object displayed on a first display surface of a transparent holographic display screen; determining, in conjunction with the input operation, a movement trajectory of the virtual interactive object, a first appearance state feature of the virtual interactive object relative to an eye position of the first user, and a second appearance state feature of the virtual interactive object relative to an eye position of a second user, after a current moment; displaying the virtual interactive object having the movement trajectory and the first appearance state feature on the first display surface of the transparent holographic display screen; and displaying the virtual interactive object having the movement trajectory and the second appearance state feature on a second display surface of the transparent holographic display screen.

A light field display system is implemented in a mobile device to present the user with holographic content which includes at least one holographic object, providing the user with an immersive operational experience. The system generates and presents holographic content for the user. In one embodiment, the system receives a command from the user. In some embodiments, the presented holographic content may comprise a holographic user interface that is used by the system to receive the commands from the user of the mobile device. Subsequently, the system recognizes the received commands, determines one or more computational commands for execution by the system, and executes the determined computational command.

A light field (LF) display system for displaying holographic content within an adult entertainment context is disclosed. The LF display system includes a plurality of LF displays that, in one embodiment, are tiled to form an array of LF displays within an environment and the LF display system may customize a viewer's experience using artificial intelligence (AI) and machine learning (ML) models that track and respond to each viewers movements and/or requests in the environment, their behaviors (e.g., body language, facial expressions, tone of voice, etc.) through various sensors (e.g., cameras, microphones, LF display sensors, etc.). Accordingly, the result is an adult entertainment environment customize for each viewer including AI holographic performers that engage viewers within the environment.

The present invention concerns a method and apparatus for the modulation of an acoustic field for providing tactile sensations. A method of creating haptic feedback using ultrasound is provided. The method comprises the steps of generating a plurality of ultrasound waves with a common focal point using a phased array of ultrasound transducers, the common focal point being a haptic feedback point, and modulating the generation of the ultrasound waves using a waveform selected to produce little or no audible sound at the haptic feedback point.

A cab having a human-machine interface to generate a holographic image in order to control comfort equipment installed in the cab. The human-machine interface includes: a camera capable of capturing images representing a gaze of an occupant, one image generation unit having (a) a computer capable of calculating the position of the location of the occupant's gaze from the captured images, the computer being adapted to generate the digital holographic image according to the position of the occupant's gaze, (b) a spatial light modulator receiving the generated digital holographic image, and (c) a light source illuminating the spatial light modulator. The human-machine interface also includes a reflector reflecting the light beams emitted by the spatial light modulator into a visualizing window to form a holographic image positioned between the windscreen and the seat.

Examples are disclosed that relate to computing devices, head-mounted display devices, and methods for displaying holographic objects using slicing planes or volumes. In one example a computing device causes a display system to display a holographic object associated with a holographic volume, the holographic object occluding an occluded holographic object that is not displayed. Location data of at least a portion of a hand is received from a sensor. The location data of the hand is used to locate a slicing plane or a slicing volume within the holographic volume. Based on the location of the slicing plane or the slicing volume, at least a portion of the occluded holographic object is displayed via the display system.

A light filed (LF) display system for displaying holographic performance content (e.g., a live performance) to viewers in a venue. The LF display system in the venue includes LF display modules tiled together to form an array of LF modules. The array of LF modules create a performance volume (e.g., a stage) for displaying the performance content in the venue. The array of LF modules displays the performance content to viewers in viewing volumes. The LF display system can be included in a LF presentation network. The LF presentation network allows holographic performance content to be recorded at one location and displayed (concurrently or non-concurrently) at another location. The LF presentation network includes a network system to manage the digital rights of the holographic performance content.
