Visual Progress Notification for Automated Musical Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Performers in actual performances struggle to synchronize and ascertain the progress of automatic performances without clear visual cues, relying solely on auditory feedback.
Innovation Solution
A performance system comprising a performance controller for automatic musical piece execution and a notification controller to visually notify performers of the progress through a dynamic notification image displayed on a notification device, synchronized with the actual performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the performer relies on auditory feedback to ascertain the progress of automatic performance, then the system remains simple, but the performer cannot appropriately ascertain the progress of the automatic performance
Solution Approach 1:
A notification device is introduced as an intermediary between the automatic performance system and the performer. This device displays visual progress information (such as scrolling lyrics or performance milestones) that mediates the communication of performance status, allowing the performer to ascertain progress without directly monitoring auditory output.
Solution Approach 2:
The system transitions from purely auditory feedback to multi-sensory feedback by adding a visual dimension. The notification device presents performance progress in a different sensory modality (visual rather than auditory), enabling the performer to track progress through a complementary channel that does not compete with the musical auditory experience.
2Reliability
If visual notification is added to help performers track progress, then synchronization improves, but device complexity increases
Solution Approach 1:
The notification device is designed to serve multiple functions: it displays performance progress, provides visual cues for synchronization, and can adapt its content based on the performance state. This multi-functionality justifies the added complexity by delivering multiple benefits from a single added component.
Solution Approach 2:
The system implements a feedback loop where the notification device continuously monitors performance progress and provides real-time visual feedback to the performer. This feedback mechanism enables the performer to adjust their timing and maintain synchronization with the automatic performance components.
Data Source
AI summary
A performance system to allow a performer of an actual performance to more appropriately ascertain the progress of an automatic performance by a performance device. The performance system comprises a performance controller that causes a performance device to carry out an automatic performance of a musical piece, and a notification controller that causes a notification device to carry out an operation to visually notify a performer of an actual performance of a musical piece of the progress of the automatic performance.
