Holographic reality system, multiview display, and method

A holographic reality multiview display comprising:

• an array of multiview pixels configured to provide a plurality of different views of a multiview image, a multiview pixel comprising a plurality of sub-pixels configured to modulate a plurality of directional light beams having directions corresponding to view directions of the different views;
• a light guide configured to guide light in a propagation direction along a length of the light guide as guided light;
• an array of multibeam elements distributed along the length of the light guide, each multibeam element being configured to scatter out from the light guide a portion of the guided light to form the plurality of directional light beams and provide the plurality of directional light beams to a corresponding multiview pixel;
• a position sensor configured to monitor a position of a hand of a user relative to a virtual control within the multiview image without contact between the user and the holographic reality multiview display;
• and
• a virtual haptic feedback unit configured to provide virtual haptic feedback to the user using one or more of ultrasonic pressure and air pressure, the virtual haptic feedback being provided based on the monitored position of the hand, an extent of the virtual haptic feedback corresponding to an extent of the virtual control.

A method of holographic reality system operation, comprising:

• displaying multiview content as a multiview image using a multiview display of the holographic reality system, the multiview display comprising a light guide that guides light in a propagation direction along a length of the light guide as guided light, the multiview display further comprising a plurality of multibeam elements distributed along the length of the light guide a multibeam element of the multibeam element plurality scattering out from the light guide a portion of the guided light as a plurality of directional light beams having different principal angular directions that correspond to different views of the multiview display;
• monitoring a position of a hand of a user using a position sensor of the holographic reality system without physical contact between the user and the holographic reality system;
• and
• providing virtual haptic feedback to the user using a virtual haptic feedback unit, the virtual haptic feedback being based on the monitored position of the hand and being provided using one or more of ultrasonic pressure and air pressure without physical contact between the user and the holographic reality system, wherein an extent of the virtual haptic feedback corresponds to an extent of a virtual control within the multiview image.
