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 light filed (LF) display system for displaying holographic content (e.g., a holographic film or holographic content to augment a film) to viewers in a cinema. The LF display system in the cinema 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 cinema. The array of LF modules displays the holographic content to viewers in viewing volumes. The LF display system can be included in a LF film network. The LF film network allows holographic content to be created at one location and presented at another location. The LF film network includes a network system to manage the digital rights of the holographic performance content.

A system for displaying a holographic image of an object behind a real object surface, including a computing unit for computing data for displaying a three-dimensional image of an object, a location measurement unit for measuring a location of a surface of a real object, a display for displaying the three dimensional image of the object, wherein the computing unit is adapted to compute data to display the three-dimensional image of the object at least partly behind the surface of the real object. Related apparatus and methods are also described.

A method for providing tactile feedback in a display system including using a display to show an image of a virtual object in a viewing space, using a touch detector to detect a user touching a real object within the viewing space, and providing a location of the touching to the display. Related apparatus and methods are also described.

A light field (LF) display system for augmentation of a vehicle. The LF display system includes LF display modules that form a surface (e.g., interior and/or exterior) of a vehicle. The LF display modules each have a display area and are tiled together to form a seamless display surface that has an effective display area that is larger than the display area. The LF display modules present holographic content from the effective display area.

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.

Presenting a three-dimensional (3D) holographic visual and haptic warning is provided. An indication that a first individual who needs supervision is approaching a situation is received. A three-dimensional (3D) holographic visual and haptic warning is presented to the first individual who needs supervision prior to the first individual reaching the situation.

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.

One disclosed example provides a computing device comprising a logic subsystem comprising a processor, and memory storing instructions executable by the logic subsystem. The instructions are executable to display via a display system one or more holographic objects, receive depth image data from a depth image sensor, detect a user input setting a trajectory for a selected holographic object, in response to detecting the user input setting the trajectory for the selected holographic object, determine the trajectory for the selected holographic object set by the user input, determine, based upon the depth image data and the trajectory, a surface intersected by the trajectory of the selected holographic object, and display via the display system the selected holographic object as travelling along the trajectory and changing in form upon encountering the surface.

Mixed reality glasses allow, a user to input into the glasses, to operate a device sanitarily. The glasses are connected, to the device wirelessly. The user views holograms in mid-aid air, while looking through the glasses. The holograms are input buttons, for the device. The user's input into the glasses, activates the holographic input buttons. User input devices in the glasses detect the user's input. User input devices include, an eye tracker, a voice recognition device, an eye gaze and hand gesture input device, a touch input device, and a thought input device. The devices operated by the glasses, may include, an elevator, a smart toilet, and a medical device. The user operates the device, touch freely, without touching the device's physical input buttons. Contact with harmful bacteria is deceased by operating the device, touch freely, which avoids bacteria, that may be on the device's input buttons.
