Video Pause Timing Correction via Motion Acceleration Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote maintenance scenarios, there is a time lag between the user's intention to pause a video and the actual pause instruction being received, causing the video to be paused at an unintended time, which can hinder clear observation of a specific object or part.
Innovation Solution
An information processing apparatus that records user motions until a video pause instruction is given and displays a still image from a time point earlier when the motion acceleration first exceeds a predetermined threshold, allowing the video to be paused at the intended moment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the user performs an operation for pausing the video, then the video is paused, but a time lag arises between the user's intention to pause and the actual pause execution
Solution Approach 1:
The system performs preliminary action by detecting user motion (pre-pause indication) before the actual pause instruction is given. When acceleration exceeds a threshold, the system identifies this as an intention to pause and automatically pauses the video at the appropriate moment, eliminating the delay between user intention and video pause.
2Ease of operation
If the video is paused at the time point when the pause instruction is received, then the pause function is executed, but the video may not be paused at the intended time point when the specific object is clearly displayed
Solution Approach 1:
The system uses feedback by continuously monitoring user motion (acceleration data) and using this information to determine the optimal pause moment. The feedback loop detects when the user is about to pause based on motion patterns and adjusts the pause timing to match the user's intention, ensuring the video pauses when the specific object is clearly displayed.

AI summary
An information processing apparatus includes a processor configured to: record a motion of a user made until a video pause instruction to pause displayed video is given; and display a still image in the video displayed at a second time point earlier than a first time point, the first time point being a time point at which the video pause instruction is received, the second time point being a threshold time point at which acceleration involved with the motion of the user first exceeds a predetermined threshold and which is a most recent threshold time point.
