Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If automatic sound production is provided to support beginners, then sound production timing accuracy is improved, but the user's sense of personal performance is degraded
Solution Approach 1:
The system performs preliminary detection of performance actions within the early press period before the actual sound production timing. By detecting user input in advance and preparing the corresponding sound production, the system can automatically correct timing without requiring real-time intervention, thus maintaining user autonomy while improving timing accuracy.
Solution Approach 2:
The system provides implicit feedback by detecting performance actions and automatically adjusting sound production timing. This feedback mechanism operates in the background without disrupting the user's performance flow, allowing timing correction while preserving the user's sense of personal performance.
2Manufacturing precision
If the system detects performance actions and corrects timings automatically, then timing accuracy is improved, but the complexity of the control system increases
Solution Approach 1:
The control system performs preliminary detection and preparation within the early press period, establishing timing corrections in advance. This approach simplifies the real-time control requirements by pre-processing timing adjustments, reducing the computational complexity during actual sound production.
Solution Approach 2:
The system segments the time axis into distinct periods (early press period, sound production timing, etc.), allowing independent processing and control strategies for each segment. This temporal segmentation simplifies the overall control logic by breaking down the complex timing correction task into manageable, time-specific operations.
3Manufacturing precision
If the early press period is set to detect performance actions, then timing correction effectiveness is improved, but the risk of detecting unintended actions increases
Solution Approach 1:
The system applies different detection criteria and processing rules to different time periods. The early press period has specific detection parameters optimized for anticipating user input, while other periods have different rules. This localized quality approach allows effective timing correction in the early press period without compromising overall detection reliability.
Solution Approach 2:
By performing detection and preparation in advance during the early press period, the system can apply more stringent and reliable detection criteria without time pressure. This preliminary detection allows for more accurate discrimination of intentional performance actions from unintended inputs, improving reliability while maintaining correction effectiveness.

AI summary
An information processing apparatus includes: a storage storing a program; and a processor that performs control in accordance with the program, wherein a sound production timing is a timing of producing a sound of a note, the sound production timing being specified in a musical piece; and an early press period is between an early time point and the sound production timing, the early time point being earlier than the sound production timing by a predetermined time. In a situation that a performance action is detected within the early press period, the processor causes a sound production unit to produce a sound corresponding to the performance action at the sound production timing. In a situation that no performance action is detected within the early press period or at the sound production timing, the processor does not cause the sound production unit to produce a sound at the sound production timing.
