Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively acquire videos of operation screens for operator training, leading to prolonged learning times for operators.
Innovation Solution
A video acquisition support apparatus and method that includes a control module to capture, add meta information, and store videos of operation screen interactions, allowing for efficient video storage and retrieval based on operation content and operator identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operators learn operations through traditional training methods, then they can operate the device, but the training period takes a long time
Solution Approach 1:
The patent creates video copies of actual operation screen interactions, allowing operators to learn from recorded demonstrations instead of experiencing the full learning curve. The video acquisition apparatus captures and stores operation videos that can be replayed during training, effectively copying expert performance for novice learning.
Solution Approach 2:
The system performs preliminary action by pre-recording operation videos before training sessions. Operators can review these pre-prepared videos at their own pace, allowing them to familiarize themselves with operations in advance of actual hands-on training, thereby reducing the overall training period.
2Ease of operation
If operation videos are recorded without meta information, then storage is simpler, but video retrieval and identification become difficult
Solution Approach 1:
The patent introduces meta information as an intermediary layer between the video content and the retrieval system. This meta information includes operation screen identifiers, timestamps, and other contextual data that enable efficient searching and retrieval without requiring complex video analysis, thus balancing ease of operation with manageable data structure complexity.
3Reliability
If all operation videos are stored without selection, then comprehensive coverage is achieved, but storage space and data management become burdensome
Solution Approach 1:
The system applies the extraction principle by selectively capturing only relevant operation videos based on predefined criteria such as operation type, screen identifier, and importance level. Instead of storing all possible videos, the apparatus extracts and stores only those that are most valuable for training purposes, reducing data volume while maintaining training completeness.

AI summary
Provided is a technology that can effectively acquire video of an operation of an operation screen of an operation device. A video acquisition support apparatus 40 includes a control module 950 configured to control an operation device 30. The control module executes a specific control process including: a video acquisition process configured to acquire a video of an operation of an operation screen 30a when an operator OP operates the operation screen 30a of the operation device; a meta information addition process configured to add meta information including at least an operation content operated by the operator on the operation screen to the acquired video; and a video storage process configured to store the acquired video in a storage device 952 together with the meta information added to the video.
