Interaction information may indicate how one or more users interacted with the video content(s). The interaction information may indicate a user's spatial selections of video content as a function of progress through the video content. The interaction information may be received at once (e.g., interaction information for one or more users may be received after the user(s) have finished interacting with the video content) or over a period of time (e.g., interaction information for one or more users may be received as the user(s) interact with the video content). Receive component 102 may continually/periodically monitor one or more users' interactions with the video content to receive the interaction information and/or may receive the interaction information in response to a user/system prompt.
Video content may refer to media content that may be consumed as one or more videos. Video content may include one or more videos stored in one or more formats/container, and/or other video content. A video may include a video clip captured by a video capture device, multiple video clips captured by a video capture device, and/or multiple video clips captured by separate video capture devices. A video may include multiple video clips captured at the same time and/or multiple video clips captured at different times. A video may include a video clip processed by a video application, multiple video clips processed by a video application and/or multiple video clips processed by separate video applications.
In some implementations, the video content may include one or more of spherical video content, virtual reality content, and/or other video content. Spherical video content may refer to a video capture of multiple views from a single location. Spherical video content may include a full spherical video capture (360 degrees of capture) or a partial spherical video capture (less than 360 degrees of capture). Spherical video content may be captured through the use of one or more cameras/image sensors to capture images/videos from a location. The captured images/videos may be stitched together to form the spherical video content.
Virtual reality content may refer to content that may be consumed via virtual reality experience. Virtual reality content may associate different directions within the virtual reality content with different viewing directions, and a user may view a particular directions within the virtual reality content by looking in a particular direction. For example, a user may use a virtual reality headset to change the user's direction of view. The user's direction of view may correspond to a particular direction of view within the virtual reality content. For example, a forward looking direction of view for a user may correspond to a forward direction of view within the virtual reality content.
Spherical video content and/or virtual reality content may have been captured at one or more locations. For example, spherical video content and/or virtual reality content may have been captured from a stationary position (e.g., a seat in a stadium). Spherical video content and/or virtual reality content may have been captured from a moving position (e.g., a moving bike). Spherical video content and/or virtual reality content may include video capture from a path taken by the capturing device(s) in the moving position. For example, spherical video content and/or virtual reality content may include video capture from a person walking around in a music festival.
In some implementations, the video content may include one or more visual elements. One or more visual elements may correspond to one or more objects and/or events captured within the video content. One or more visual elements may include one or more visual elements corresponding to one or more objects and/or one or more events. For example,
Spatial selections of the video content may refer to the one or more portions of space within the video content with which the user interacted. User's spatial selections of the video content may remain the same or change as a function of progress through the video content. For example, the user may view the video content without changing the direction of view (e.g., the user may view a “default view” of video content captured at a music festival, etc.). The user may view the video content by changing the directions of view (e.g., the user may change the direction of view of video content captured at a music festival to follow a particular band, etc.). Other types of spatial selections of the video content are contemplated.
The spatial selections of the video content may include one or more viewing directions of the video content selected by the users as the function of progress through the video content. Viewing directions of the video content may correspond to orientations of fields of view within which the users interacted with the video content. In some implementations, the viewing directions of the video content selected by the users may be characterized by a yaw parameter, a pitch parameter, and/or other parameters. In some implementations, the viewing directions of the video content selected by the users may be further characterized by a roll parameter, and/or other parameters. A yaw parameter may define an amount of yaw rotation for video content. A pitch parameter may define an amount of pitch rotation for video content. A roll parameter may define an amount of raw rotation for video content.
For example,
A pitch parameter may define an amount of rotation of video content 300 around pitch axis 320. For example, a 0-degree rotation of video content 300 around pitch axis 320 may correspond to a viewing direction that is level with respect to horizon. A 45-degree rotation of video content 300 around pitch axis 320 may correspond to a viewing direction that is pitched up with respect to horizon by 45-degrees. A 90 degree rotation of video content 300 around pitch axis 320 may correspond to a viewing direction that is pitched up with respect to horizon by 90-degrees (looking up). A −45-degree rotation of video content 300 around pitch axis 320 may correspond to a viewing direction that is pitched down with respect to horizon by 45-degrees. A −90 degree rotation of video content 300 around pitch axis 320 may correspond to a viewing direction that is pitched down with respect to horizon by 90-degrees (looking down).
A roll parameter may define an amount of rotation of video content 300 around roll axis 330. For example, a 0-degree rotation of video content 300 around roll axis 330 may correspond to a viewing direction that is upright. A 90 degree rotation of video content 300 around roll axis 330 may correspond to a viewing direction that is rotated to the right by 90 degrees. A −90-degree rotation of video content 300 around roll axis 330 may correspond to a viewing direction that is rotated to the left by 90-degrees.
In some implementations, the spatial selections of the video content may include one or more viewing extents of the video content selected by the users as the function of progress through the video content. Viewing extents of the video content may correspond to sizes of the field of view (zoom) within which the users interacted with the video content.
In some implementations, the spatial selections of the video content may be determined based on one or more of the users' viewing, tagging, sharing, and/or extraction of one or more portions of the video content, and/or other information. For example, users' spatial selections of the video content may be determined based on users' viewing of one or more portions of the video content via virtual reality headsets and/or other video players that allow the users to change the direction, rotation, and/or zoom of view. Users' directions, rotations, and zooms of viewing the video content may be tracked so that for different points of progress within the content, information indication the direction, rotation, and/or zoom of users' views may be stored.
Users' spatial selections of the video content may be determined based on users' tagging of one or more portions of the video content with one or more information. For example, users may tag one or more portions of the video content corresponding to a particular direction, rotation, and/or zoom as a highlight, with comments, and/or with other information.
User's spatial selections of the video content may be determined based on users' sharing of one or more portions of the video content. For example, users may share one or more portions of the video content corresponding to a particular direction, rotation, and/or zoom as a link, multiple links, an image, multiple images, a video clip, and/or multiple video clips.
Users' spatial selections of the video content may be determined based on users' extraction of one or more portions of the video content. For example, users may extract one or more portions of the video content corresponding to a particular direction, rotation, and/or zoom as an image, multiple images, a video clip, and/or multiple video clips. User's spatial selections of the video content determined based on users' other interactions with one or more portions of the video content are contemplated.
For example,
Identify component 104 may be configured to identify related video content. Related video content may refer one or more video content that may be of interest to a user. The related video content may include one or more video content similar to the video content (and/or portions of the video content) with which the user interacted. The related video content may include visuals captured at/near the same time or at/near the same location as the video content with which the user interacted. The related video content may include visual captured at different times or at different locations from the video content with which the user interacted. The related video content may be identified based on the spatial selections of the video content and/or other information. For example, identify component 104 may identify related video content based on spatial selection 500 shown in
In some implementations, the related video content may be identified based on machine learning. For example, a database may include information relating to prior user interactions of the video content with which the user interacted. The prior user interactions may include interactions of the present user and/or other users. The database may include information relating to other video content viewed and/or requested by the users after interacting with the video content as shown in
The database may include information relating to spatial selections of video content by one or more users associated with different video preferences. For example, the database may include information relating to spatial selections of the video content by users with video preference for surfing and users with video preference for hiking. Identify component 104 may compare the present user's spatial selections 500 of the video content with other users' spatial selections of the video content. Based on the comparison, identify component 104 may identify one or more users whose spatial selections mostly closely resembles spatial selection 500. For example, spatial selection 500 may more closely resemble spatial selections of the user(s) with video preference for hiking than spatial selections of the user(s) with video preference for surfing. Based on the resemblance, identify component 104 may identify as related video content those video content including/relating to hiking.
The database may include information relating to spatial selections of video content by one or more users associated with different user identifications. For example, the database may include information relating to spatial selections of the video content by users identified as men and users identified as women. Identify component 104 may compare the present user's spatial selections 500 of the video content with other users' spatial selections of the video content. Based on the comparison, identify component 104 may identify one or more users whose spatial selections mostly closely resembles spatial selection 500. For example, spatial selection 500 may more closely resemble spatial selections of the user(s) identified as women than spatial selections of the user(s) identified as men. Based on the resemblance, identify component 104 may identify as related video content those video content of interest to/viewed by women.
In some implementations, identifying related video content based on the spatial selections of the video content may include associating the user with one or more groups and identifying the related video content based on the group(s) with which the user is associated and/or other information. A group may refer to a collection of users who share one or more commonalities. One or more commonalities may be a temporary characteristic of the users or a permanent characteristic of the users. The users in a group may be characterized by one or more common characteristics. A common characteristic may refer to a feature and/or a quality shared by the users in a group. Common characteristics may include one or more of a common gender, a common age group, a common location, a common interest, and/or other common characteristics.
The user may be associated with one or more groups based on the spatial selections of the video content and/or other information. For example, the database may include information relating to spatial selections of video content by one or more users associated with different groups. For example, the database may include information relating to spatial selections of the video content by users associated with a music band A and users associated with a music band B. Identify component 104 may compare the present user's spatial selections 500 of the video content with other users' spatial selections of the video content. Based on the comparison, identify component 104 may identify one or more users whose spatial selections mostly closely resembles spatial selection 500. For example, spatial selection 500 may more closely resemble spatial selections of the user(s) associated with the music band A than spatial selections of the user(s) associated with the music band B. Based on the resemblance, identify component 104 may identify as related video content those video content including/relating to music band A. In some implementations, the related video content may be characterized as being of interest to one or more groups with which the user is associated. For example, the related video content may include video content characterized as being of interest to a group associated with music band A.
In some implementations, related video content may include particular view(s) within the related video content. For example, related video content may include visuals relating to the music band A, music band B, and/or other music bands. Different views of the related video content may exist. Different views of the related video content may include different orientations of fields of view within which the related video content may be viewed. The different orientations of the fields of view may be defined as a function of progress through the related video content. For example, one view of the related video content may include particular orientations of the fields of view that focus on music band A, and another view of the related video content may include particular orientations of the fields of view that focus on music band B. Based on spatial selection 500 indicating the user's interest in music band A, related video content may include a view of the related video content that focuses on music band A.
In some implementations, related video content may include one or more portions of the video content with which the user interacted. For example, receive component 102 may receive interaction information indicating how a user interacted with a first part of video content. Identify component 104 may, based on the user's spatial selections of the first part of the video content, identify related video content that includes a particular view of the second part of the video content. For example, the user's spatial selections of the first part of the video content may indicate the user's interest in music band A. The related video content may include a particular view of the second part of the video content that focuses on music band A. The related video content may include a view of the entire video content that focuses on music band A (allowing a user to view the video content from the start with a focus on music band A). The related video content may be characterized by one or more types of projections (e.g., stereographic projection, little planet projection, tunnel view projection, equirectangular projection, rectilinear projection, etc.).
In some implementations, associating the user with one or more groups may include determining one or more interests of the user corresponding to one or more of objects or events based on the spatial selections of the video content and/or other information. The spatial selections of the video content may include one or more of the viewing directions of the video content selected by the user that include one or more of the visual elements. For example, as shown in
One or more interests of the user corresponding to particular objects/events may be determined based on one or more of the viewing directions of the video content selected by the user including the visual element(s) corresponding to the particular objects/events and/or other information. For example, an interest of the user corresponding to a music band/music band playing a song may be determined based on the viewing directions of the video content selected by the user including the visual element(s) corresponding to the music band/music band playing a song.
In some implementations, one or more interests of the user corresponding to particular objects/events may be determined further based on the spatial selections of the video content indicating the user changing the viewing directions of the video content to center on the corresponding visual element(s). For example, a user may change the viewing directions of video content 300 so that the view of video content 300 changes from those shown in
In some implementations, one or more interests of the user corresponding to particular objects/events may be determined further based on the spatial selections of the video content indicating the user changing the viewing directions of the video content to follow the corresponding visual element(s). For example, a music band may be playing a song in the portion of video content 300 indicated as performance area 600. The music band may move across the stage so that the performance area 600 moves to the right, as shown in
In some implementations, one or more interests of the user corresponding to particular objects/events may be determined further based on the spatial selections of the video content indicating the user changing the viewing extents of the video content to zoom in on the corresponding visual elements. For example, a user may change the viewing directions of video content 300 so that the view of video content 300 changes from those shown in
In some implementations, one or more interests of the user corresponding to particular objects/events may be determined further based on the spatial selections of the video content indicating more than one change. For example, a user's interest corresponding to the music band/music band playing a song may be determined based on the user changing the view of the video content 300 to following the music band/music banding playing the song and zooming in on the music band/music band playing the song.
In some implementations, one or more interests of the user corresponding to particular objects/events may be determined further based on the spatial selections of the video content meeting or exceeding one or more thresholds and/or other information. For example, the spatial selections of the video content may need to center on the corresponding visual element(s) for a threshold duration. The spatial selections of the video content may need to center on the corresponding visual element(s) a threshold number of times. The spatial selections of the video content may need to follow the corresponding visual element(s) for a threshold duration. The spatial selections of the video content may need to zoom in on the corresponding visual element(s) for a threshold duration. The spatial selections of the video content may need to zoom in on the corresponding visual element(s) a threshold number of times. The spatial selections of the video content may need to zoom in on the corresponding visual element(s) at a threshold magnification.
In some implementations, associating the user with one or more groups may include associating the user with one or more interest groups based on one or more interests of the user and/or other information. For example, individual interest groups may be characterized by a common interest of the users associated with the individual interest groups. A common interest may refer to an interest commonly shared by the users in a group. For example, an interest of the user may correspond to a particular music band. The particular music band may be associated with a particular genre of music.
A first interest group may be characterized by a common interest of the users associated with the first interests group. The common interest may correspond to the particular music band. A second interest group may be characterized by a different common of the users associated with the second interest group. The different common interest may correspond to the particular genre of music. The interest corresponding to the particular music band may be a subset of the interest corresponding to the particular genre of music.
The user may be associated with a first interest group based on the interest of the user including the common interest corresponding to the particular music band and/or other information. The user may be associated with the second interest group based on the interest of the user corresponding to the particular interest group being a subset of the interest correspond to the particular genre of music.
The related video content may be identified further based on the interest group with which the user is associated and/or other information. Related video content may be characterized as being of interest to one or more interest groups with which the user is associated. The related video content may include one or more video content based on the user being associated with a particular interest group and/or other information. The related video content may include one or more video content that include visual element(s) corresponding to the common interest(s) and/or other visual elements. For example, related video content may include video relating to the particular music band and/or particular genre of music based on the user being associated with the particular interest group corresponding to the particular music band and/or the particular genre of music.
Offer component 106 may be configured to offer the related video content to the user. Offering the related video content user may include providing one or more links to the related video content, transmitting the related video content to the user, and/or other offerings of the related video content to the user. For example, offer component 106 may provide a list of related video content (e.g., a recommended view list, etc.), which may allow a user to selected and/or view the related video content. Offer component 106 may transmit the related video content to the user. In some implementations, offer component 106 may switch from providing a recommended view list to directly transmitting the related video content. For example, identify component 104 may identify only one related video content. Instead of providing a recommended view list listing a single video content, offer component 106 may transmit the video content to the user. Other types of offering of the related video content are contemplated.
In some implementations, the related video content may be offered to the user based on one or more rankings of the related video content and/or other information. For example, offer component 106 may store and/or access information in a database relating to prior views of the related video content by the user and/or other users. Related video content may be ranked by the user and/or other users. Related video content that is more often viewed in full by the user and/or other users may be ranked higher than related video content that is more often viewed only in parts. Related video content that is more often selected by the user and/or other users may be ranked higher than related video content that is selected less often. Ranking may be determined based on user preference. For example, a user may prefer video content of certain duration(s) and/or longer/shorter duration(s).
While the present disclosure may be directed to video content, one or more other implementations of the system may be configured for other types media content. Other types of media content may include one or more of audio content (e.g., music, podcasts, audio books, and/or other audio content), multimedia presentations, photos, slideshows, and/or other media content.
