Spherical Video Orientation Detection and Dynamic Field of View Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of spherical video segments often 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 determine and adjust 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 structure is simple and stable, but users miss content in other views and perspectives
Solution Approach 1:
The display field of view is made dynamic by detecting display orientation through sensors and automatically adjusting the viewed portion of the spherical video segment in real-time. This allows the system to capture and present different views and perspectives without requiring complex multi-display configurations, thereby reducing information loss while maintaining manageable system complexity.
2Adaptability or versatility
If the display field of view is adjusted to show more perspectives, then content accessibility improves, but the system complexity increases
Solution Approach 1:
The system automatically detects display orientation using sensors and autonomously determines which portion of the spherical video segment to present based on the detected orientation. This self-adjusting mechanism provides versatile viewing perspectives without requiring complex manual controls or user intervention, thereby enhancing adaptability while keeping the control system relatively simple.
3Loss of time
If users manually search for events of interest in spherical video segments, then the system requires minimal processing, but users spend excessive time locating highlights
Solution Approach 1:
The system performs preliminary analysis of the spherical video segment to identify events of interest before user viewing. By pre-detecting and marking significant events, the system enables users to quickly navigate to highlights without manually searching through the entire video, thereby significantly reducing the time users spend locating events while implementing reasonable automation levels.

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.
