Head Mounted Display Real-Time Video Segment Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for recording and editing video data for work guidance require significant labor and time, especially when retaking images to correct failed attempts, as they necessitate cutting and splicing successful and failed segments after the recording is complete.
Innovation Solution
A head-mounted display device equipped with an image display, imager, and processor that acquires and generates unitary moving images, determines whether to replace existing images with retaken ones, and splices them together to create a coherent continual moving image, reducing the need for after-the-fact editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional video recording methods are used to capture work processes, then complete recording of all work segments is achieved, but significant labor and time are required for editing to remove failed segments
Solution Approach 1:
The system performs preliminary action by automatically detecting and marking successful work segments during the recording process itself, rather than requiring post-recording editing. The determination unit identifies successful segments in real-time based on predetermined criteria, and the splicing unit prepares the final video by automatically assembling only the successful segments before the recording session ends, thereby eliminating the need for time-consuming post-editing while maintaining complete and accurate work documentation
2Manufacturing precision
If manual editing of video segments is performed to remove failed attempts, then clean work recordings are produced, but extensive labor is required for cutting and splicing
Solution Approach 1:
The system applies self-service by enabling automatic identification and segmentation of successful work attempts through the determination unit, which evaluates recorded segments against predetermined success criteria. The splicing unit then automatically assembles these identified segments into the final video without requiring manual cutting or splicing operations. This automated self-service mechanism maintains high video quality by precisely selecting only successful segments while eliminating the extensive manual labor previously required for editing
Solution Approach 2:
The invention substitutes the mechanical manual editing process with an automated electronic system. Instead of physically cutting and splicing video tapes or files manually, the determination unit electronically identifies successful segments and the splicing unit electronically assembles them into the final video output. This replacement of mechanical editing operations with automated electronic processing dramatically reduces editing labor while maintaining or improving the precision of segment selection and final video quality
3Reliability
If retaking of failed work segments is allowed, then better work examples are obtained, but the process becomes more complex requiring replacement and splicing of multiple video segments
Solution Approach 1:
The system handles retaking complexity through preliminary action by automatically managing the replacement process during the recording session. When a successful retake is identified by the determination unit, the system automatically replaces the corresponding failed segment in the video sequence without requiring complex post-processing. The splicing unit maintains an organized structure of successful segments, automatically assembling them in the correct sequence, thereby obtaining high-quality work examples while keeping the processing system relatively simple through automated segment management
Solution Approach 2:
The system applies copying by creating and maintaining separate storage of successful video segments that can be automatically substituted for failed ones. The determination unit identifies successful attempts, and the splicing unit copies these successful segments into the final video sequence in place of failed attempts. This copying mechanism simplifies the retake process by treating successful segments as replaceable units that can be automatically assembled into the final output without complex manual intervention
