Music Score Overlay Display for Practice Feedback

Solution Overview

Problem

Existing music score display devices do not effectively allow users to check their practice results and progress while playing, as previous playing states and results are not intuitively displayed alongside the music score, hindering rapid improvement.

Innovation Solution

A music score display device that includes a display controller, memory for storing playing results, and a graph image generator to overlay practice result graphs onto the music score, allowing users to view their progress intuitively during playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If practice result images are displayed in the upper area of the music score display region, then practice results can be checked, but the images may not be noticed when the player's eyes are directed at the music score

Engineering Contradiction:

Improvepractice result visibilityVSAvoidplayer attention focus

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent transitions from displaying practice results in the upper area (2D plane) to overlaying graph images directly on the music score measures (spatial integration). This dimensional change allows practice results to be viewed in the same visual field as the music score, eliminating the need for players to shift attention between separate display areas.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent merges the music score display and practice result visualization into a single integrated display. By overlaying graph images on the music score measures, the system combines two previously separate information streams (music notation and practice metrics) into one unified visual interface, ensuring both are viewed simultaneously without competing for attention.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of information

If only images showing states of practice and results of previous plays are displayed, then practice feedback is provided, but the display becomes fundamentally divergent from the general process of playing while looking at a music score

Engineering Contradiction:

Improvepractice feedback informationVSAvoidnatural playing flow

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent merges the music score display and practice result visualization into a single integrated display. By overlaying graph images on the music score measures, the system combines two previously separate information streams (music notation and practice metrics) into one unified visual interface, ensuring both are viewed simultaneously without competing for attention.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The graph image serves as an intermediary element that provides practice feedback without interrupting the natural flow of reading the music score. The overlayed graph acts as a mediator between the player's performance and the music notation, allowing continuous viewing of both the score and performance metrics without requiring separate display areas or interrupted viewing patterns.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If the graph image is displayed without overlaying on the music score, then the graph can be clearly visible, but the player cannot check practice results while viewing the music score

Engineering Contradiction:

Improvepractice result accessibilityVSAvoidgraph image visibility

Core Design Contradiction:

Loss of informationVSIllumination intensity

Solution Approach 1:

The patent transitions from displaying practice results in the upper area (2D plane) to overlaying graph images directly on the music score measures (spatial integration). This dimensional change allows practice results to be viewed in the same visual field as the music score, eliminating the need for players to shift attention between separate display areas.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent applies local quality by overlaying graph images specifically on the measure regions of the music score where practice results are relevant. This localized placement ensures that graph visibility is optimized within the context of the music score structure, allowing players to check practice results for specific measures while maintaining overall score visibility.

Inventive Principle:

Principle #3Local quality

AI summary

A music score display device displays a music score representing a predetermined piece of music at a display, and stores a playing result for each measure of the music score in a memory when the piece is played. On the basis of the playing results of the measures stored in the memory, the music score display device generates graph images representing the playing results of the measures, and displays the generated graph images of the measures, superposed on images of the corresponding measures of the music score displayed at the display, such that the images of the measures are visible.
