Abstract

Exemplary perspective display systems and methods are disclosed herein. An exemplary method includes a perspective display system acquiring visual data representative of a camera view of a user space associated with a display screen, determining, based on the visual data, a position of a user within the user space, identifying, based on the position of the user, a viewable region of an image, and displaying, on the display screen, the viewable region of the image, the displayed viewable region of the image representing a perspective view of the image based on the position of the user. In certain examples, the method further includes the perspective display system detecting a movement of the user to another position within the user space and updating the display on the display screen in real time in accordance with the movement to display another viewable region of the image on the display screen.

Claims

1. A method comprising:

acquiring, by a perspective display system, visual data representative of a camera view of a user space associated with a display screen;

determining, by the perspective display system based on the visual data, a position of a user within the user space;

identifying, by the perspective display system based on the position of the user, a viewable region of an image; and

displaying, by the perspective display system on the display screen, the viewable region of the image, the displayed viewable region of the image representing a perspective view of the image based on the position of the user.

2. The method of claim 1, further comprising:

detecting, by the perspective display system, a movement of the user to another position within the user space; and

updating, by the perspective display system, the display on the display screen in real time in accordance with the movement to display another viewable region of the image on the display screen, the another viewable region of the image representing another perspective view of the image based on the another position of the user.

3. The method of claim 2, wherein the updating comprises displaying at least one of a panning, a tilting, and a zooming from the viewable region of the image to the another viewable region of the image on the display screen.

4. The method of claim 1, wherein the image comprises a real-time live video image.

5. The method of claim 4, further comprising receiving, by the perspective display system in real time, a video feed carrying the real-time live video image, wherein the real-time live video image comprises end-user-generated content captured by at least one video camera.

6. The method of claim 4, wherein the real-time live video image comprises a panoramic video image.

7. The method of claim 4, wherein the real-time live video image comprises a three-dimensional real-time live video image.

8. The method of claim 1, wherein the determining of the position of the user comprises:

visually detecting a predefined tracking initiation gesture performed by the user within the user space;

locking onto a physical feature of the user in response to the detecting of the predefined tracking initiation gesture; and

tracking the physical feature of the user within the user space.

9. The method of claim 8, wherein the physical feature of the user comprises at least one eye of the user.

10. The method of claim 1, wherein the determining of the position of the user comprises determining three-dimensional coordinates of a physical feature of the user within the user space based on the visual data.

11. The method of claim 1, wherein the identifying of the viewable region of the image is based on a congruence of triangles in a geometric model.

12. The method of claim 1, wherein the determining of the position of the user is performed without the user utilizing a user input device within the user space.

13. The method of claim 1, embodied as computer-executable instructions on at least one non-transitory computer-readable medium.

14. A method comprising:

receiving, by a video distribution subsystem, an incoming real-time video feed carrying data representative of a live video image captured by a video camera;

transmitting, by the video distribution subsystem, an outgoing real-time video feed carrying data representative of the live video image to a video access subsystem;

receiving, by the video access subsystem, the outgoing real-time video feed carrying data representative of the live video image;

detecting, by the video access subsystem, a position of a user within a user space associated with a display screen;

identifying, by the video access system based on the position of the user, a viewable region of the live video image; and

displaying, by the video access system on the display screen, the viewable region of the live video image, the displayed viewable region of the live video image representing a perspective view of the live video image based on the position of the user.

15. The method of claim 14, further comprising:

detecting, by the video access subsystem, a movement of the user to another position within the user space; and

updating, by the video access subsystem, the display on the display screen in real time in accordance with the movement to display another viewable region of the live video image on the display screen, the another viewable region of the live video image representing another perspective view of the live video image based on the another position.

16. The method of claim 14, wherein the live video image comprises end-user-generated content captured and provided to the video distribution subsystem in real time.

17. The method of claim 14, wherein the live video image comprises a live panoramic video image.

18. The method of claim 14, wherein the live video image comprises a live three-dimensional video image.

19. The method of claim 14, wherein the detecting of the position of the user comprises:

visually detecting a predefined tracking initiation gesture performed by the user within the user space;

locking onto a physical feature of the user in response to the detecting of the predefined tracking initiation gesture; and

tracking the physical feature of the user within the user space.

20. The system of claim 14, further comprising:

receiving, by the video distribution subsystem, a request for the live video image from the video access subsystem; and

selecting, by the video distribution subsystem in response to the request, the incoming real-time video feed from a plurality of incoming real-time video feeds for transmission to the video access subsystem.

21. The method of claim 14, embodied as computer-executable instructions on at least one non-transitory computer-readable medium.

22. A system comprising:

a video distribution subsystem that

receives an incoming real-time video feed carrying data representative of a live video image captured by a video camera, and

distributes an outgoing real-time video feed carrying data representative of the live video image over a network; and

a video access subsystem communicatively coupled to the video distribution subsystem by way of the network and that

receives the outgoing real-time video feed carrying data representative of the live video image;

detects a position of a user within a physical user space associated with a display screen; and

displays, on the display screen, a perspective view of viewable region of the live video image based on the position of the user.

23. The system of claim 22, wherein the video distribution subsystem

receives a request for the live video image from the video access subsystem, and

selects, in response to the request, the incoming real-time video feed from a plurality of incoming real-time video feeds for transmission to the video access subsystem.

24. The system of claim 22, wherein the video access subsystem comprises at least one of a set-top box device, a mobile phone device, a gaming console, and a tablet computer.

25. The system of claim 22, wherein the network comprises at least one of a subscriber television network and a mobile phone network.
