Abstract

A light field (LF) display system comprises a LF display assembly. The LF display assembly comprises one or more LF display modules and is configured to present holographic merchandise to a patron in a viewing volume of the LF display system with the LF display modules. The LF display system is also configured to receive patron input in response to presentation of the holographic merchandise. The LF display system may track patron movement within the viewing volume of the LF display system. The LF display system may update presentation of the holographic merchandise based on the received patron input and/or the tracked patron movement. The LF display system may further provide other sensory feedback via a sensory feedback system. The LF display system may further comprise a patron profiling system for storing information for a patron under a patron profile. The LF display system may further present information via a holographic assistant presented by the LF display modules.

First claim

1 . A light field (LF) display system comprising:
a LF display assembly comprising one or more LF display modules and configured to present holographic merchandise that includes one or more holographic objects in a holographic object volume to a patron located in a viewing volume of the one or more LF display modules, wherein the LF display system is configured to receive an input in response to presentation of the holographic merchandise.

2 . The LF display system of claim 1 , wherein the LF display assembly updates the presentation of one of the holographic objects corresponding to the received input.

3 . The LF display system of claim 2 , wherein updating presentation of the holographic object is one of:
scaling the holographic object in the holographic object volume of the LF display system; moving the holographic object in the holographic object volume of the LF display system; and changing an appearance of the holographic object.

4 . The LF display system of claim 2 , wherein updating presentation of the holographic object is one of:
displaying another holographic object different from the holographic object; displaying information about the holographic object; displaying a configuration of the holographic object; and displaying a physical setting for the holographic object.

5 . The LF display system of claim 1 , wherein the holographic object is one or more of:
one or more rooms in a house; one or more furniture in the house; a portion of a vehicle; a consumer electronic device; and a physical good.

6 . The LF display system of claim 1 , wherein the holographic merchandise is associated with a digital asset, wherein the received input corresponds to a purchase of the digital asset.

7 . The LF display system of claim 1 , wherein the holographic merchandise is associated with a service to be rendered, wherein the received input corresponds to a purchase of the service.

8 . The LF display system of claim 1 , further comprising:
a computer-readable storage medium storing one or more patron profiles including characteristics of one or more patrons.

9 . The LF display system of claim 8 , wherein the characteristics include one or more actions performed by a patron; wherein the LF display system is further configured to record one or more user inputs in the patron profile for the user.

10 . The LF display system of claim 9 , wherein the actions include one or more of:
a purchase of an item; an interaction with one or more holographic objects; a viewing history of one or more holographic objects; and one or more user inputs provided to the LF display system.

11 . The LF display system of claim 8 , wherein the characteristics include one or more of: demographic information of a user, work experience, educational history, gender, income, money spent on purchases, hobbies, location, age, viewing history, time spent on items, categories of items previously viewed, and purchase history.

12 . The LF display system of claim 8 , wherein the holographic merchandise is selected for presentation based on the characteristics in a patron profile for the patron.

13 . The LF display system of claim 12 , wherein the holographic merchandise is selected with a machine learning model using the characteristics in the patron profile.

14 . The LF display system of claim 8 , wherein the LF display system is configured to transmit one or more characteristics in a patron profile to an external system.

15 . The LF display system of claim 8 , wherein one or more characteristics in a patron profile are retrieved from an external system.

16 . The LF display system of claim 1 , wherein each LF display module has a display surface from where the holographic objects are projected, wherein a seamless display surface is formed by tiling the display surfaces of the one or more LF display modules.

17 . The LF display system of claim 16 , wherein one of the holographic objects is displayed between the patron and the seamless display surface, behind the seamless display surface such that seamless display surface is between the holographic object and the patron, or split by the seamless display surface.

18 . The LF display system of claim 16 , wherein each LF display module comprises:
an energy device layer that is configured to provide a plurality of energy source locations, an energy waveguide layer with a plurality of energy waveguides, with each waveguide configured to project energy from at least one energy source location into at least one specific direction from the display surface depending on the energy source location, in accordance with a 4D light-field function, to form the holographic objects, and wherein viewing perspectives of the holographic objects change based in part on the patron's position in a viewing volume relative to the holographic object within the holographic object volume.

19 . The LF display system of claim 18 , wherein the LF display modules are further configured to receive a light field from an environment.

20 . The LF display system of claim 19 , wherein the LF display assembly is further configured to receive the input based on the light field from the environment received by the one or more LF display modules.

21 . The LF display system of claim 18 , the energy waveguide layer further comprising:
an array of electrostatic speakers coupled to a plurality of energy waveguides, the array of electrostatic speakers comprising:
at least one transparent membrane configured to generate acoustic energy when driven, and
a plurality of electrodes configured to acoustically drive the transparent membrane, each electrode of the plurality of the electrodes located between one or more energy waveguides of the plurality of energy waveguides.

22 . The LF display system of claim 1 , further comprising:
a tracking system configured to track movement of the patron within the viewing volume of the LF display system.

23 . The LF display system of claim 22 , wherein the tracking system comprises one or more cameras configured to capture images of an area in front of the LF display modules.

24 . The LF display system of claim 23 , wherein the one or more cameras are external to the LF display assembly.

25 . The LF display system of claim 22 , wherein the tracking system comprises one or more depth sensors configured to detect the depth of objects in front of the LF display modules.

26 . The LF display system of claim 22 , wherein the LF display assembly updates presentation of the holographic object based on movement of the patron tracked by the tracking system.

27 . The LF display system of claim 22 , wherein the tracking system is further configured to:
