Abstract

In some embodiments, holographic presentations despite using holographic displays having limited viewing angles may be facilitated. In some embodiments, a user may be detected via one or more sensors associated with a holographic display system, where the holographic display system being configured with a first viewing angle. Based on the detection of the user, a direction of the user may be determined. The first viewing angle of the holographic display system may also be determined. For example, the holographic display system may determine a current first viewing angle. Based on the direction of the user, the first viewing angle may be adjusted such that the user becomes within the adjusted first viewing angle of the holographic display system.

First claim

What is claimed is:

1 . A system for facilitating holographic presentations despite using holographic displays having limited viewing angles, the system comprising:
one or more processors executing computer program instructions that, when executed, cause operations comprising:
detecting a user within a distance threshold of a holographic display device, the holographic display device being configured with multiple viewing angles and enabled to simultaneously provide holographic presentations via the multiple viewing angles, the multiple viewing angles comprising a first viewing angle having a first set of angle arms and a second viewing angle having a second set of angle arms different from the first set of angle arms;
in response to detection of the user within the distance threshold, determining a relative direction of the user with respect to the holographic display device;
selecting, based on the relative direction of the user, the first viewing angle over the second viewing angle of the multiple viewing angles of the holographic display device for a first holographic presentation to the user; and
adjusting, based on the selection, the first viewing angle of the holographic display device for the first holographic presentation to the user by moving components of the holographic display device to cause the relative direction of the user to be within the adjusted first viewing angle of the holographic display device.

2 . The system of claim 1 , further comprising:
in conjunction with adjusting the first viewing angle of the holographic display device, adjusting the second viewing angle of the holographic display device by moving components of the holographic display device such that there is no overlap between the adjusted first and second viewing angles.

3 . A method comprising:
detecting a user via one or more sensors associated with a holographic display system, the holographic display system being configured with multiple viewing angles and enabled to simultaneously provide holographic presentations via the multiple viewing angles; determining a direction of the user based on the detection of the user; selecting, based on the direction of the user, a first viewing angle over a second viewing angle of the multiple viewing angles of the holographic display system for a first holographic presentation to the user; and adjusting, based on the selection, the first viewing angle of the holographic display system for the first holographic presentation to the user such that the user becomes within the adjusted first viewing angle of the holographic display system.

4 . The method of claim 3 , further comprising:
in conjunction with adjusting the first viewing angle of the holographic display system, adjusting the second viewing angle of the holographic display system such that there no overlap between the adjusted first and second viewing angles.

5 . The method of claim 3 , further comprising:
in conjunction with adjusting the first viewing angle of the holographic display system, adjusting the second viewing angle of the holographic display system such that there is less than a threshold degree of overlap between the adjusted first and second viewing angles.

6 . The method of claim 3 , further comprising:
in conjunction with adjusting the first viewing angle of the holographic display system, adjusting the second viewing angle of the holographic display system such that there is less than three degrees of overlap between the adjusted first and second viewing angles.

7 . The method of claim 3 , further comprising:
selecting, based on a direction of a second user, the second viewing angle of the multiple viewing angles of the holographic display system for a second holographic presentation to the second user; and while the user is within the adjusted first viewing angle, adjusting, based on the selection of the second viewing angle, the second viewing angle of the holographic display system for the second holographic presentation to the second user such that the second user becomes within the adjusted second viewing angle of the holographic display system.

8 . The method of claim 3 , further comprising:
selecting, based on a predicted future location of the user, a third viewing angle of the multiple viewing angles of the holographic display system for the first holographic presentation to the user; and while the user is within the adjusted first viewing angle, adjusting, based on the selection of the third viewing angle, the third viewing angle of the holographic display system such that the predicted future location becomes within the adjusted third viewing angle of the holographic display system.

9 . The method of claim 8 , wherein adjusting the third viewing angle comprises, while the user is within the adjusted first viewing angle, expanding an overall viewing angle for the first holographic presentation by adjusting, based on the selection of the third viewing angle, the third viewing angle of the holographic display system such that (i) the predicted future location becomes within the adjusted third viewing angle of the holographic display system and (ii) the adjusted first and third viewing angles only partially overlaps with one another by one or more degrees.

10 . The method of claim 3 , wherein adjusting the first viewing angle comprises:
initially adjusting, based on the selection of the first viewing angle, the first viewing angle of the holographic display system at a first time such that a current location of the user becomes within the adjusted first viewing angle of the holographic display system at the first time; predicting a future location of the user; and prior to the user arriving at the predicted future location, further adjusting, based on the predicted future location of the user, the first viewing angle of the holographic display system such that (i) the current location of the user remains within the adjusted first viewing angle of the holographic display system and (ii) the predicted future location of the user becomes within the adjusted first viewing angle of the holographic display system.

11 . One or more non-transitory computer-readable media comprising instructions that, when executed by one or more processors, cause operations comprising:
detecting a user via one or more sensors associated with a holographic display system, the holographic display system being configured with a first viewing angle; determining a direction of the user based on the detection of the user; determining the first viewing angle of the holographic display system; and adjusting, based on the direction of the user, the first viewing angle of the holographic display system for a first holographic presentation to the user such that the user becomes within the adjusted first viewing angle of the holographic display system.

12 . The media of claim 11 , wherein determining the first viewing angle comprises selecting, based on the direction of the user, the first viewing angle over a second viewing angle of the holographic display system for the first holographic presentation to the user, and
wherein adjusting the first viewing angle comprises adjusting, based on the selection, the first viewing angle of the holographic display system for the first holographic presentation to the user such that the user becomes within the adjusted first viewing angle of the holographic display system.

13 . The media of claim 11 , wherein the holographic display system is configured with multiple viewing angles and enabled to simultaneously provide holographic presentations via the multiple viewing angles.
