Abstract

In a method and supporting system for intelligent buffering of large scale videos, a video presentation includes a plurality of sub-videos, each associated with a field of view. During presentation of the large scale video, sub-videos within a user'"'"'s field of view are loaded and presented to the user, and sub-videos in proximate fields of view are loaded for potential presentation. On identifying a change in the user'"'"'s field of view to one of the proximate fields of view, sub-videos are loaded for presentation within the new field of view. In a method and supporting system for seamless transitions in large scale videos, a video having a plurality of sub-videos is provided for presentation to a user, and distraction levels based on video content and user interactions are tracked. A transition point for the video is identified based on one or both transaction levels, and a sub-video is changed to a different sub-video at the transition point.

Claims

1. A computer-implemented method comprising:

providing for presentation to a user a video comprising a plurality of sub-videos;

tracking a first distraction level based on content in the video;

tracking a second distraction level based on one or more actions of the user during the presentation of the video;

identifying, during the presentation of the video, a transition point based on at least one of the first distraction level and the second distraction level;

changing a first one of the sub-videos to a different sub-video at the transition point.

2. The method of claim 1, wherein the video is presented in a simulated three-dimensional space.

3. The method of claim 1, wherein a subplurality of the sub-videos is presented simultaneously to the user.

4. The method of claim 1, wherein tracking the first level of distraction comprises identifying at least one of an object movement in a particular sub-video, an object occlusion in a particular sub-video, a distracting video scene, and distracting audio.

5. The method of claim 1, wherein tracking the second level of distraction comprises identifying at least one of a change in a field of view of the user, an eye focus of the user, and a movement direction of the user.

6. The method of claim 1, wherein the first distraction level is at least one of determined prior to the presentation of the video and determined during the presentation of the video.

7. The method of claim 1, wherein identifying the transition point comprises determining at a particular point in time that a combination of the first distraction level and the second distraction level exceed a threshold level of distraction.

8. The method of claim 1, wherein identifying the transition point comprises determining at a particular point in time that the first distraction level exceeds a threshold level of distraction.

9. The method of claim 1, wherein identifying the transition point comprises determining at a particular point in time that the second distraction level exceeds a threshold level of distraction.

10. The method of claim 1, wherein the changing to the different sub-video occurs immediately upon identifying the transition point.

11. The method of claim 1, wherein the first sub-video is presented within a field of view of the user.

12. The method of claim 1, wherein a particular sub-video comprises a plurality of video frames, each frame comprising a portion of a frame of a larger video.

13. The method of claim 1, wherein a particular sub-video comprises a plurality of video frames, each frame comprising a plurality of distinct portions.

14. A system comprising:

at least one memory storing computer-executable instructions; and

at least one processor for executing the instructions stored on the memory, wherein execution of the instructions programs the at least one processor to perform operations comprising;

providing for presentation to a user a video comprising a plurality of sub-videos;

tracking a first distraction level based on content in the video;

tracking a second distraction level based on one or more actions of the user during the presentation of the video;

identifying, during the presentation of the video, a transition point based on at least one of the first distraction level and the second distraction level;

changing a first one of the sub-videos to a different sub-video at the transition point.

15. The system of claim 14, wherein the video is presented in a simulated three-dimensional space.

16. The system of claim 14, wherein a subplurality of the sub-videos is presented simultaneously to the user.

17. The system of claim 14, wherein tracking the first level of distraction comprises identifying at least one of an object movement in a particular sub-video, an object occlusion in a particular sub-video, a distracting video scene, and distracting audio.

18. The system of claim 14, wherein tracking the second level of distraction comprises identifying at least one of a change in a field of view of the user, an eye focus of the user, and a movement direction of the user.

19. The system of claim 14, wherein the first distraction level is at least one of determined prior to the presentation of the video and determined during the presentation of the video.

20. The system of claim 14, wherein identifying the transition point comprises determining at a particular point in time that a combination of the first distraction level and the second distraction level exceed a threshold level of distraction.

21. The system of claim 14, wherein identifying the transition point comprises determining at a particular point in time that the first distraction level exceeds a threshold level of distraction.

22. The system of claim 14, wherein identifying the transition point comprises determining at a particular point in time that the second distraction level exceeds a threshold level of distraction.

23. The system of claim 14, wherein the changing to the different sub-video occurs immediately upon identifying the transition point.

24. The system of claim 14, wherein the first sub-video is presented within a field of view of the user.

25. The system of claim 14, wherein a particular sub-video comprises a plurality of video frames, each frame comprising a portion of a frame of a larger video.

26. The system of claim 14, wherein a particular sub-video comprises a plurality of video frames, each frame comprising a plurality of distinct portions.
