Dynamic Spherical Video Field of View Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of spherical video segments may miss content available in other views and perspectives due to limited display fields of view, leading to an unsatisfactory viewing experience.
Innovation Solution
A system and method that dynamically adjusts the display field of view based on the orientation of a two-dimensional display, allowing users to view different angles and perspectives within a spherical video segment by moving and orienting the display, while providing zoom controls and the ability to record and share specific moments of interest as a two-dimensional video segment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users view spherical video segments through a fixed display field of view, then the display device remains simple and easy to operate, but users miss content available in other views and perspectives
Solution Approach 1:
The display field of view is made dynamic by detecting the orientation of the display device and automatically adjusting which portion of the spherical video segment is presented. This allows the system to adapt to user viewing direction without requiring complex manual controls, thereby reducing information loss while maintaining operational simplicity.
Solution Approach 2:
The system uses sensor feedback to detect display orientation and automatically adjusts the displayed field of view accordingly. This closed-loop feedback mechanism ensures that users consistently see the content they are oriented toward, eliminating the need for users to manually search for content across different views.
2Adaptability or versatility
If the display field of view is adjusted to show more perspectives, then users can access more content, but the device complexity increases
Solution Approach 1:
The system performs automatic field of view adjustment based on display orientation without requiring user intervention. The self-service mechanism uses onboard sensors to autonomously determine and present the appropriate viewing perspective, providing adaptability while avoiding complex control interfaces.
3Loss of time
If users manually search through the entire spherical video segment to find highlights, then the system remains simple, but users spend excessive time searching
Solution Approach 1:
The system pre-processes the spherical video segment to identify and tag highlights and events of interest before playback. This preliminary action allows the system to quickly present relevant content when users interact with the display, eliminating the need for manual searching while maintaining system simplicity through automated background processing.
Solution Approach 2:
The patent replaces manual mechanical searching with automated computational identification of highlights. By using algorithms to detect and tag significant events in advance, the system substitutes user manual exploration with automated intelligent content identification, significantly reducing time loss without adding complex user-facing functionality.

AI summary
Systems and methods for presenting and viewing a spherical video segment is provided. The spherical video segment including tag information associated with an event of interest may be obtained. The tag information may identify a point in time and a viewing angle at which the event of interest is viewable in the spherical video segment. An orientation of a two dimensional display may be determined based upon output signals of a sensor. A display field of view within the spherical video segment may be determined and presented on the display based upon the orientation of the display. The display field of view may be captured as a two dimensional video segment. If the viewing angle of the event of interest is outside the display field of view proximate the point in time, a notification may be presented within the display field of view.
