Seamless transitions in large-scale video
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 distraction levels, and a sub-video is changed to a different sub-video at the transition point.
1. A computer-implemented method comprising:
providing for presentation to a user a video comprising a plurality of sub-videos, wherein a subplurality of the plurality of sub-videos are simultaneously played to the user, wherein the subplurality of sub-videos comprises a first subset of sub-videos and a second subset of sub-videos, wherein each sub-video in the first subset is at least partially within a field of view of the user, and wherein each sub-video in the second subset is fully within the field of view of the user;
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,
wherein the first and second distraction levels each comprise a variable value within a range representing an extent to which the user is distracted;
identifying, during the presentation of the video, a transition point based on the first distraction level and/or the second distraction level, wherein identifying the transition point comprises:
measuring a first value corresponding to the first distraction level;
measuring a second value corresponding to the second distraction level;
calculating a combined distraction value by combining the first value and the second value; and
determining that, at a particular point in time, the combined distraction value exceeds a threshold level of distraction; and
at the transition point, changing each sub-video in the first subset that is at least partially within the field of view of the user to a different sub-video and not changing any of the sub-videos in the second subset that is fully within the field of view of the user to a different sub-video.
2. The method of claim 1 , wherein the video is presented in a simulated three-dimensional space.
3. The method of claim 1 , wherein tracking the first level of distraction comprises identifying an object movement in a particular sub-video, an object occlusion in a particular sub-video, a distracting video scene, and/or distracting audio.
4. The method of claim 1 , wherein tracking the second level of distraction comprises identifying a change in a field of view of the user, an eye focus of the user, and/or a movement direction of the user.
5. The method of claim 1 , wherein the first distraction level is determined prior to the presentation of the video and/or determined during the presentation of the video.
6. The method of claim 1 , wherein the changing to the different sub-video occurs immediately upon identifying the transition point.
7. 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.
8. The method of claim 1 , wherein a particular sub-video comprises a plurality of video frames, each frame comprising a plurality of distinct portions.
9. The method of claim 1 , wherein each sub-video in the first subset is partially within the field of view of the user and partially outside the field of view of the user.
10. 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, wherein a subplurality of the plurality of sub-videos are simultaneously played to the user, wherein the subplurality of sub-videos comprises a first subset of sub-videos and a second subset of sub-videos, wherein each sub-video in the first subset is at least partially within a field of view of the user, and wherein each sub-video in the second subset is fully within the field of view of the user;
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,
wherein the first and second distraction levels each comprise a variable value within a range representing an extent to which the user is distracted;
identifying, during the presentation of the video, a transition point based on the first distraction level and/or the second distraction level, wherein identifying the transition point comprises:
measuring a first value corresponding to the first distraction level;
measuring a second value corresponding to the second distraction level;
calculating a combined distraction value by combining the first value and the second value; and
determining that, at a particular point in time, the combined distraction value exceeds a threshold level of distraction; and
at the transition point, changing each sub-video in the first subset that is at least partially within the field of view of the user to a different sub-video and not changing any of the sub-videos in the second subset that is fully within the field of view of the user to a different sub-video.
11. The system of claim 10 , wherein the video is presented in a simulated three-dimensional space.
12. The system of claim 10 , wherein tracking the first level of distraction comprises identifying an object movement in a particular sub-video, an object occlusion in a particular sub-video, a distracting video scene, and/or distracting audio.
13. The system of claim 10 , wherein tracking the second level of distraction comprises identifying a change in a field of view of the user, an eye focus of the user, and/or a movement direction of the user.
14. The system of claim 10 , wherein the first distraction level is determined prior to the presentation of the video and/or determined during the presentation of the video.
15. The system of claim 10 , wherein the changing to the different sub-video occurs immediately upon identifying the transition point.
16. The system of claim 10 , wherein a particular sub-video comprises a plurality of video frames, each frame comprising a portion of a frame of a larger video.
17. The system of claim 10 , wherein a particular sub-video comprises a plurality of video frames, each frame comprising a plurality of distinct portions.
18. The system of claim 10 , wherein each sub-video in the first subset is partially within the field of view of the user and partially outside the field of view of the user.
