Notification Control for Frame Identification in Moving Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moving image reproduction techniques fail to efficiently identify and notify users of specific frames during skipping operations, such as in golf swing motions, limiting user interaction and engagement.
Innovation Solution
A notification control apparatus and method that acquires and identifies frames through skipping operations, determines if they match predetermined postures, and provides notification via vibration patterns, sound, or display modes, allowing users to intuitively identify and interact with specific frames in a moving image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If skipping operation is used to navigate through frames, then navigation speed is improved, but ability to identify specific frames is worsened
Solution Approach 1:
The system provides visual feedback by displaying a thumbnail image of the current frame during skipping operation, and audio feedback through notification sounds when a predetermined frame is reached. This feedback mechanism allows users to maintain awareness of frame identification accuracy while navigating at high speed.
Solution Approach 2:
A thumbnail image display serves as an intermediary between the skipping operation and frame identification. The thumbnail provides visual confirmation of the current frame content without requiring the user to stop the skipping operation, thus maintaining navigation speed while improving identification accuracy.
2Measurement precision
If notification is provided for every frame, then frame identification is improved, but user disturbance is worsened
Solution Approach 1:
Notification is applied selectively rather than uniformly to all frames. The system provides notification only when a predetermined frame matching specific criteria (e.g., impact posture in golf swing) is identified during skipping operation. This local application of notification improves frame identification accuracy for important frames while minimizing user disturbance from excessive notifications.
3Reliability
If multiple notification methods are provided, then notification effectiveness is improved, but device complexity is worsened
Solution Approach 1:
The notification control unit serves multiple functions: it controls visual notification through display, audio notification through speaker, and haptic notification through vibration mechanism. This multi-functionality approach improves notification effectiveness by providing multiple channels while avoiding the need for separate dedicated components for each notification type, thus managing device complexity.
