VR Content Reference Position Control for Faster Region Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extracting regions from VR content for all frames require users to specify positions for each frame, leading to numerous operation steps and a time-consuming process.
Innovation Solution
An electronic device with a display control unit that displays frame images and a timeline area, a calculation unit that automatically sets reference positions for frame images based on previously set positions, and a control unit that separates specified and non-specified periods in the timeline area for easy user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users manually specify positions for all frames to extract regions from VR content, then the extraction can be performed for all frames, but the number of operation steps increases and the process becomes time-consuming
Solution Approach 1:
The system performs automatic reference position setting for frames where no user specification is provided, using previously set reference positions and track information to calculate and set positions autonomously, eliminating the need for manual user input for every frame
Solution Approach 2:
The system maintains and utilizes previously set reference positions to automatically determine positions for subsequent frames, performing the extraction setup work in advance based on earlier user specifications rather than requiring fresh input for each frame
2Manufacturing precision
If users specify reference positions for all frames, then accurate region extraction can be achieved, but the time required for setting increases significantly
Solution Approach 1:
The calculation unit automatically calculates reference positions for unspecified frames based on track information connecting previously set positions, maintaining accuracy without requiring manual user input for every frame
Solution Approach 2:
The system maintains continuous reference position information across frames through track data, allowing automatic propagation of position specifications while preserving the accuracy and intent of user-defined positions
3Ease of operation
If the timeline area displays all periods uniformly, then the interface is simple, but users cannot easily distinguish specified periods from non-specified periods
Solution Approach 1:
The display control unit visually distinguishes specified periods from non-specified periods in the timeline area, likely through different colors or visual indicators, enabling users to easily identify the status of each period without complicating the interface

AI summary
An electronic device sequentially displays a plurality of frame images of a moving content on a screen and displays a timeline area corresponding to a reproduction period of the plurality of frame images on the screen. The electronic device calculates a position on a track connecting reference positions of a first frame image and a second frame image, sets the calculated position as the reference position of the third frame image, and sets a plurality of fourth frame images existing in a specified period specified by a user to maintain one reference position specified by the user. The electronic device displays the specified period and other periods separately in the timeline area, and displays regions corresponding to the reference positions set for each of the plurality of frame images in sequence on the screen.
