Music Display System with Simultaneous Jump Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic music displays face challenges with small screen sizes, leading to usability issues due to page turns and structural symbols, which can be difficult to manage without manual interaction, especially for musicians playing instruments that require both hands.
Innovation Solution
A computer-implemented method that maintains a music document and displays a main view with potential jump targets, allowing hands-free operation by identifying the source and destination portions through user indications, such as gaze or audio signals, to update the display and facilitate seamless navigation during performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sheet music is presented electronically without significant changes to the layout, then the traditional musical structure is preserved, but usability issues arise due to page turns and jumps
Solution Approach 1:
The patent displays multiple pages simultaneously in a two-dimensional layout, allowing musicians to see both current and future pages at once. This eliminates the need for sequential page turns while preserving the logical flow of the music through visual spatial arrangement.
Solution Approach 2:
The system pre-loads and displays multiple pages of sheet music before they are needed, allowing musicians to anticipate upcoming changes and transitions. This eliminates the disruption of sudden page turns during performance.
2Quantity of substance
If the number of pages is reduced by using repetition symbols, then paper usage is minimized, but it becomes difficult for users to know how many pages to turn
Solution Approach 1:
Multiple pages are displayed simultaneously in vertical or horizontal arrangement, providing visual navigation cues about upcoming pages and repetitions without requiring musicians to interpret traditional repetition symbols and calculate page turns.
Solution Approach 2:
The system introduces visual indicators and annotations that mediate between the compressed musical notation and the user's understanding of navigation, showing exactly which pages will be displayed and in what order.
3Ease of operation
If page turns are timed to match musical durations, then hands-free operation is enabled, but timing and tempo variations cause misalignment
Solution Approach 1:
By displaying multiple pages simultaneously, the system eliminates the need for timed page turns entirely. Musicians can visually track their position in the music across multiple pages without manual intervention, making the system reliable regardless of tempo variations.
4Ease of operation
If a fully unrolled presentation is used, then navigation is simplified, but the structure and repetition of music is lost
Solution Approach 1:
The patent presents multiple pages in a simultaneous two-dimensional layout rather than a linear unrolled sequence. This maintains the compact structure of the music while providing enhanced navigation visibility, showing the relationship between different sections and repetitions spatially.

AI summary
A user interface presents structural musical information in a score in a way where both the start and the end points of each jump in the score are visible simultaneously. Each jump is presented in a manner that allows the user to select during performance, which one of different alternatives to choose, when approaching a decision point like a repeat in the song.
