Electronic Musical Score Apparatus Annotation Layering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic musical score apparatuses lack manageability of user writings and operability during performances, particularly in shared environments where deleted handwriting data cannot be restored and page order relationships between displays are unclear.
Innovation Solution
An electronic musical score apparatus with two openable and closable display units, featuring a memory for musical score data, touch input for annotations, and communication capabilities to manage and share annotation data, allowing for write history tracking and view-ahead page display with customizable page order.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handwriting data is managed separately from musical score data, then manageability of writings is improved, but ability to restore deleted writings is lost
Solution Approach 1:
The patent segments annotation data into multiple independent layers (first annotation data, second annotation data, etc.), allowing each layer to be managed separately while preserving the ability to restore previous versions by switching between layers
Solution Approach 2:
The patent implements a mechanism where previous versions of annotation data are discarded from active display but recovered through layer management, enabling users to restore deleted writings by switching to preserved annotation layers
2Reliability
If multiple annotation data are stored for write history, then restoration capability is improved, but data management complexity increases
Solution Approach 1:
Annotation data is segmented into distinct layers with clear hierarchical relationships, simplifying the management of multiple versions through a structured layer system rather than unorganized data storage
Solution Approach 2:
The system preliminarily organizes annotation data into numbered layers during the writing process, preparing the data structure in advance to facilitate easy restoration without complex retrieval operations
3Ease of manufacture
If icons are constantly displayed on target screens, then visual awareness is improved, but page order relationship recognition is worsened
Solution Approach 1:
Icons are displayed periodically or conditionally rather than constantly, appearing only when needed to indicate page order relationships, thus maintaining visual awareness without continuously obstructing the view of page relationships

AI summary
An electronic musical score apparatus 1 includes display units D1, D2 connected to each other to be openable and closeable, and can convert a writing made on display portions 11, 12 by a user into annotation data 1, associated with musical score page data but being manageable separately from the musical score page data, and store the annotation data 1. When an image of the associated musical score page data is displayed together with an image of the annotation data 1 on the display portions 11, 12 and then the user rewrites the annotation data 1, the electronic musical score apparatus 1 can provide a write history for the annotation data 1 by storing the annotation data 1 before the rewriting as first-generation annotation data 1 and storing the annotation data 1 after the rewriting as second-generation annotation data 1.
