Music Movement Display Device Dynamic Viewpoint Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music playing movement display devices struggle to provide an intuitive visual representation of finger movements during musical performance, especially when reviewing specific techniques, due to limitations in display format changes and automatic viewpoint adjustment, making it difficult for players to analyze delicate finger movements effectively.
Innovation Solution
A music playing movement display device that includes a memory for storing music playing information, structural data, and movement information, along with a determination unit and display controller, which allows for dynamic display modes based on the stored data to visually enhance finger movement recognition, enabling easy switching between normal and enlarged views, and automatic viewpoint adjustments during music playing technique displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire keyboard is displayed to show finger movements, then the keyboard layout is complete, but the finger appears small and difficult to recognize
Solution Approach 1:
The keyboard display is segmented into multiple regions, and the camera functionally segments the view by allowing selective enlargement of specific keyboard regions. When a player needs to review a specific technique, the system divides the full keyboard view into multiple sub-regions and enables zooming into the relevant portion, separating the full context from the detailed view.
Solution Approach 2:
The system transitions from a two-dimensional flat display of the entire keyboard to a multi-dimensional viewing experience by adding zoom capability. This dimensional change allows the same physical display area to present both the full keyboard layout and enlarged finger movements by adjusting the viewing scale along the depth dimension.
2Extent of automation
If the display format is changed manually by the player, then the viewing angle can be adjusted, but the player cannot change the viewpoint automatically while playing music
Solution Approach 1:
The system provides self-service functionality by automatically detecting when a player needs to review a specific technique and initiating the viewpoint change without manual intervention. The camera functionally serves itself by monitoring music playing status and automatically adjusting the viewing angle to highlight relevant keyboard regions.
Solution Approach 2:
The system implements feedback by monitoring the music playing process and using this information to automatically adjust the display viewpoint. When the system detects that a player is reviewing a specific technique, it receives feedback about the player's needs and automatically adjusts the camera angle to provide the appropriate viewing perspective.
3Measurement precision
If the finger is displayed enlarged to improve recognition, then the finger movement is clearly visible, but the overall keyboard layout context is reduced
Solution Approach 1:
The keyboard is divided into multiple regions, and the system can selectively enlarge specific segments while maintaining awareness of the overall layout. When zooming into a particular keyboard region for detailed finger movement analysis, the system segments the view to show the enlarged detail while preserving contextual information about the surrounding keys and overall hand position.
Solution Approach 2:
The system resolves this contradiction by transitioning to a different dimensional representation. Instead of choosing between full context or enlarged detail in the same plane, the system uses multi-dimensional viewing capabilities to present both the overall keyboard layout and enlarged finger movements simultaneously through adjustable camera angles and zoom levels.

AI summary
A music playing movement display device includes CPU displaying a music playing movement image on a display unit based on music playing information, movement information, and structural data stored in RAM. the CPU determines whether to perform display of a music playing technique based on a music playing technique flag of the music playing information stored in the RAM, and, when determining to perform the display of the music playing technique, allows to change a display mode of the image corresponding to the music playing technique, compared to a display mode of a image corresponding to that of a case of not displaying the music playing technique.
