1Area of stationary object
If spherical video content captures a larger visual extent and field of view, then the coverage and comprehensiveness of the video content is improved, but the difficulty and time required to identify viewing directions increases
Solution Approach 1:
The system determines viewing directions in advance by analyzing sensor information from the capture device before video playback. This preliminary determination of viewing directions based on motion sensors, location sensors, and orientation data allows the system to pre-process and identify important viewing directions, eliminating the need for time-consuming manual analysis during video consumption.
Solution Approach 2:
The patent introduces sensor information as an intermediary element that bridges the gap between the capture device and the video content. Motion sensors, location sensors, and orientation sensors provide objective data about the capture context, which the system uses to automatically determine viewing directions without requiring manual intervention in the large visual extent of spherical video content.
2Measurement precision
If manual identification of viewing directions is performed in spherical video content, then accurate direction determination is achieved, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system performs self-service by automatically determining viewing directions using sensor information embedded in the video content metadata. The motion sensors, location sensors, and orientation sensors capture objective data during filming that the system then processes to identify viewing directions autonomously, eliminating the need for manual analysis while maintaining accuracy based on the actual capture context.
Solution Approach 2:
The system uses sensor information as feedback about the capture conditions to automatically adjust and determine viewing directions. By analyzing motion data, location changes, and orientation information from the capture device, the system receives feedback about how the video was filmed and uses this feedback to identify appropriate viewing directions without manual intervention.
3Productivity
If automated viewing direction determination using sensor information is implemented, then processing efficiency and productivity are improved, but the system complexity increases
Solution Approach 1:
The system achieves universality by using a standardized approach that works across different types of video content and capture devices. The sensor information processing framework is designed to handle various sensor types (motion sensors, location sensors, orientation sensors) and different video formats uniformly, reducing the need for device-specific complex processing while maintaining high productivity in viewing direction identification.

AI summary
Video information and sensor information may be obtained. The video information may define spherical video content having a progress length. The spherical video content may define visual content viewable from a point a view as a function of progress through the progress length of the spherical video content. The spherical video content may be captured by one or more image capture devices. The sensor information may characterize capture of the spherical video content. A viewing direction for the spherical video content may be determined based on the sensor information and/or other information. The viewing direction may define a direction of view for the spherical video content from the point of view as the function of progress through the progress length of the spherical video content. The spherical video content may be presented on a display based on the viewing direction.
