Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for automatically advancing pages during musical or spoken performances are limited in determining optimal page turns and providing feedback on performance errors, necessitating improved mechanisms for seamless transitions and performance improvement.
Innovation Solution
An apparatus and method that electronically analyzes audio performances, compares them to predetermined scores or scripts, and provides automated page sequencing, while offering feedback on performance deviations, including digital recording, playback, and accompaniment capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual page turning is used during performance, then the performer can control page transitions, but the flow of music or presentation is interrupted
Solution Approach 1:
The system pre-loads multiple pages of the score or presentation into memory before performance begins. During performance, pages are automatically advanced by detecting when the performer has completed a page, eliminating the need for manual page turning and preventing interruptions to the performance flow.
Solution Approach 2:
The system automatically detects page completion through audio analysis and performance monitoring, then autonomously advances to the next page without requiring manual intervention from the performer, making the system self-servicing during performance.
2Loss of time
If automated page turning is implemented, then performance flow is maintained, but the system cannot adapt to complex scores or varying performance speeds
Solution Approach 1:
The system dynamically adjusts page turning timing based on real-time audio analysis of performance tempo and detected musical structure. It monitors performance speed and automatically modifies when to advance pages to match the performer's actual tempo, adapting to both fast and slow performances and handling complex scores with varying rhythmic patterns.
Solution Approach 2:
The system continuously analyzes audio input during performance to detect tempo changes and musical cues, using this feedback to intelligently determine the optimal moment to advance pages. This feedback loop enables the system to adapt to complex scores and varying performance speeds while maintaining seamless page transitions.
3Productivity
If performance analysis and feedback are provided, then performance quality improves rapidly, but the system complexity increases
Solution Approach 1:
The system replaces the mechanical process of manual performance analysis by a teacher with an automated digital audio analysis system. The system captures performance audio, digitally processes it to detect pitch, rhythm, and accuracy, and automatically generates feedback, eliminating the need for human intervention while providing comprehensive performance analysis.
Solution Approach 2:
The system integrates multiple functions into a single unified platform: audio capture, real-time performance analysis, automated page turning, and feedback generation. This multi-functional approach consolidates what would otherwise require separate systems, managing complexity while delivering comprehensive performance improvement capabilities.
Data Source
AI summary
Speech or musical performance is electronically analyzed using DSP techniques and is compared to a stored text script or musical score, to enable display of and automated sequencing through multiple pages of the stored script or score. The performer can modify timing of sequencing if desired, for example dependent on performance speed or musical complexity. Automated highlighting or marking of measures or text assists the performer in keeping track of progress through the performance. During or after the performance, electronic comparison of the performance to the score or script provides feedback to the performer, highlighting differences between the actual performance and the desired performance as described by the score or script. Additional capabilities enhancing the learning process include digital recording and playback of the actual performance, and/or accompaniment by synthesis or playback of digital recording of other performance parts (for example, other instruments in an ensemble or other actors in a play).
