Personalized audio-visual systems

An audio-visual system includes an audio source configured to produce multiple audio. The system includes one or more multi-view (MV) pixels, each configured to emit beamlets in different directions in a beamlet coordinate system. The system includes a processor that receives a specification of multiple listening/viewing zones located in a listening/viewing zone coordinate system. The processor associates multiple audio and visual contents with the multiple listening/viewing zones, respectively, and determines an audio mapping that translates between the listening/viewing zone coordinate system and the audio source and a visual mapping that translates between the listening/viewing zone coordinate system and the beamlet coordinate system. For each of multiple audio generated from the multiple audio contents, the processor, using the audio mapping, identifies an audio parameter value to produce the audio at a corresponding listening/viewing zone. For each of multiple images generated from the multiple visual contents, the processor, using the visual mapping, identifies a bundle of beamlets from each of the MV pixels directed to a corresponding listening/viewing zone to form the image.

Temporally multiplexing backlight with asymmetric turning film

Backlights are disclosed. More particularly, temporally multiplexed backlights utilizing asymmetric turning films are disclosed. The disclosed backlights are capable of displaying a primary image to on-axis viewers while simultaneously providing a secondary image to off-axis viewers.

MULTI-PLAYER AUDIO-VIDEO INTEGRATED WITH INTERACTIVE GAME BOARD

System and methods for providing simultaneous public and private audio-video integrated with an interactive board game, where a private viewer looking through an eye filter perceives the private video while a public viewer not looking through an eye filter perceives the public video all responsive to playing the interactive board game. Means for providing private audio simultaneous with the private video are also shown. The audio-video is selectively provided during game play based at least upon the tracked game state of the interactive board game. The video output component of the system can be implemented as either a display or a projector.

System and method for displaying location dependent content

A system and method for simultaneously displaying, in plural spatially distinct zones via a multi-view display, differentiated content is disclosed. In accordance with the method, a plurality of spatially distinct zones are defined, differentiated content is assigned to the zones, a location for at least some of plural landing spots of beamlets projected by multi-view pixels of the multi-view display is estimated, the spatially distinct zone in which each said landing spots resides is determined, and beamlets associated with said some landing spots are driven to cause an appropriate content portion to be viewable at said some landing spots, as a function of location in a particular spatially distinct zone.

Designing content for multi-view display

The specification and drawings present a signage design device (SDD) and a method for using such a device for designing content for a multi-view display (MVD) intended for simultaneously displaying multiple versions of content to multiple corresponding viewing zones. The multi-view display may be a static multi-view signage print (SMVSP) or an electronic multi-view display (EMVD), as described herein.

Waveguide comprising surface relief feature and directional backlight, directional display device, and directional display apparatus comprising said waveguide

An imaging directional backlight apparatus includes a waveguide and light source array for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure in which steps may include extraction features optically hidden to guided light, propagating in a forward direction. Returning light propagating in a backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Viewing windows are formed through imaging individual light sources and defines the relative positions of system elements and ray paths. Alignment of the waveguide to mechanical and optical components may be provided by surface relief features of the waveguide arranged in regions adjacent the input surface and intermediate the light emitting regions of the light sources. Efficient, uniform operation may be achieved with low cross talk for application to autostereoscopic and privacy modes of operation.

Multi-view display viewing zone layout and content assignment

Systems and methods are described for managing a multi-view display, including user interface techniques for manipulating viewing zone information and assigning content to viewing zones in the context of the viewing area. The multi-view display system may be calibrated to a coordinate system of the viewing area. The coordinate system can be based on the physical dimensions of the viewing area, a model or other representation of the viewing area, and/or characteristics detected by a sensing system observing the viewing area. A zone management device provide a user interface showing a representation of the viewing area along with representations of established viewing zones rendered in context within the viewing area. User interface elements allow a user to add, remove, manipulate, configure viewing zones, and/or assign content to viewing zones. User interface elements can also allow a user to manipulate the representation of the viewing area.

Privacy display apparatus

An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. The directional backlight may be arranged to switch between at least a first wide angular luminance profile mode and a second narrow angular luminance profile mode. The directional backlight is arranged to illuminate an LCD with a bias electrode arranged to switch liquid crystal directors in black state pixels between a first wide angular contrast profile mode and a second narrow angular contrast profile mode. Performance of privacy operation for off-axis snoopers is enhanced in comparison to displays with only directional backlights or switchable contrast properties.
