Wide-Field Video Viewing Direction Setting With Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Videos with wide fields of view, such as spherical or panoramic views, make it difficult for users to see different spatial parts simultaneously, and specifying which spatial extents to include in a presentation or creating a two-dimensional video is time-consuming and challenging.
Innovation Solution
A system and method that allows users to set viewing directions for videos through interaction with a graphical user interface, using manual target elements and automatic object tracking to define viewing directions, enabling easy switching and intuitive framing of video content.

Engineering Contradiction Analysis
1Area of stationary object
If a wide field of view video is used, then more spatial content is captured, but it becomes difficult to see different spatial parts simultaneously
Solution Approach 1:
The patent divides the wide field of view video into multiple spatial portions or regions that can be independently viewed and manipulated. Users can select and focus on specific spatial parts within the broader field of view, effectively segmenting the visual content to improve navigability and visibility of different areas.
Solution Approach 2:
The patent introduces an additional interaction dimension by allowing users to click or interact with specific spatial portions of the video to set viewing directions. This transforms the traditional single-dimension playback into a multi-dimensional interaction model where users can navigate through spatial dimensions within the video content.
2Measurement precision
If manual specification of spatial extents is performed, then precise viewing control is achieved, but the process becomes time consuming
Solution Approach 1:
The patent implements automatic object tracking that pre-identifies and tracks relevant objects or regions within the video content. This preliminary action of automatic detection and tracking eliminates the need for manual spatial extent specification, providing both precision and time efficiency by automatically preparing the viewing directions based on detected objects.
Solution Approach 2:
The system performs self-service by automatically analyzing video content, identifying objects of interest, and setting viewing directions without requiring manual user input for each spatial specification. The automatic tracking and object recognition capabilities enable the system to autonomously determine appropriate viewing parameters.

AI summary
A graphical user interface may provide a views of a video. The graphical user interface may include a manual target element positioned over a spatial portion of the video. A user may interact with the spatial portion of the video within the manual target element to start recording viewing directions for the video. A user may interact with other spatial portions of the video to change the spatial parts of the video presented within the graphical user interface. A user may interact with the graphical user interface to utilize object tracking to record viewing directions for the video.
