Score Display Method for Single-Operation Writing Mode Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing score displaying apparatuses are not convenient for writing on scores due to the need for multiple operations and the issue of written content moving to irrelevant positions during reflow, and they also struggle to balance the visibility of notes and phrases during zooming.
Innovation Solution
A score displaying method that allows a user to switch from view mode to writing mode with a single operation, where the area for writing is enlarged relative to the surrounding area, preventing content movement and improving visibility by gradually reducing surrounding images with distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user enlarges the entire score image to see notes clearly, then the notes in the current performance position become easy to see, but it becomes difficult to grasp phrases located forward of the current position
Solution Approach 1:
The patent applies local quality by differentiating the display quality of different regions in the score. The current performance position and surrounding area are displayed at normal or enlarged size for clear visibility, while the forward area is displayed at a reduced size. This allows users to see notes clearly in the current position while still grasping the overview of forward phrases, resolving the contradiction between detailed visibility and overall comprehension.
2Loss of information
If the user reduces the entire score image to see more grand staves, then phrases located forward can be easily grasped, but the notes in the current performance position become difficult to see
Solution Approach 1:
The patent resolves this contradiction by applying local quality differently - the forward area is displayed at reduced size to show more content, while the current performance position maintains normal or enlarged display size to ensure notes remain clearly visible. This selective quality assignment allows users to grasp forward phrases while maintaining note visibility.
3Adaptability or versatility
If the user performs multiple operations (swipe, pinch-out, mode switch, pinch-in) to write on the score, then writing functionality is available, but the number of operations required is excessive
Solution Approach 1:
The patent applies merging by combining the mode switching function and the score image enlargement function into a single operation. When the user performs a pinch-out operation, the system simultaneously switches from view mode to writing mode and enlarges the score image. This eliminates the need for separate mode switching and enlargement operations, significantly reducing the total number of operations required for writing on the score.
Solution Approach 2:
The patent applies preliminary action by automatically switching to writing mode and enlarging the score image in anticipation of the user's writing intent. The system detects the pinch-out gesture and proactively prepares the writing environment before the user completes the gesture, eliminating the need for subsequent mode switching operations.
Data Source
AI summary
A controller of a score displaying apparatus operates in a view mode displaying a score on a screen of a user I/F 12, and a writing mode obtaining information indicating writing on the score via the user I/F 12. In response to one operation specifying one grand staff by a user in the view mode, the controller performs a process of enlarging an image of an image area to which the specified grand staff belongs and displaying the enlarged image on a foreground of a center of the screen, and performs a process of switching a control mode from the view mode to the writing mode.
