Virtual Instrument Layout Adaptation for Musical Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional musical instruments that generate electronic sounds based on player movements do not allow for dynamic adjustment of virtual instrument layouts in response to playing mistakes, limiting the player's ability to correct errors.
Innovation Solution
A musical instrument system equipped with a position sensor, determination unit, sound generation instruction unit, and modification unit that detects player movements, determines if the movements correspond to a virtual region, generates sound if correct, and modifies the layout to include incorrect movements, allowing for real-time adjustment of virtual instrument arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the layout information of virtual instruments is established in advance, then the system structure is simple and easy to implement, but the system cannot adapt to player mistakes or improve based on usage patterns
Solution Approach 1:
The patent implements dynamic layout information that can be modified based on player mistakes. The system transitions from static pre-established layout to dynamic adaptive layout, where the modification unit adjusts virtual instrument positions and regions in response to detected errors, allowing the system to evolve during gameplay
Solution Approach 2:
The system incorporates feedback mechanisms where the determination unit detects player mistakes by comparing actual strikes with intended targets, and this feedback is used by the modification unit to adjust layout information. This closed-loop feedback enables continuous improvement of the interface based on player performance
2Manufacturing precision
If the virtual instrument regions are fixed, then the measurement and detection of player actions is straightforward, but player accuracy cannot be improved through adaptive adjustments
Solution Approach 1:
The virtual instrument regions are implemented as dynamic rather than fixed. The modification unit adjusts the boundaries and positions of these regions based on detected player mistakes, allowing the target areas to adapt and expand to accommodate player skill levels and improve strike accuracy over time
Solution Approach 2:
The system performs preliminary detection of player mistakes by the determination unit, which identifies when strikes miss intended targets. This preliminary detection enables subsequent modification of layout information to prevent similar mistakes, proactively improving player accuracy
3Adaptability or versatility
If the layout information cannot be modified, then the system is stable and reliable, but it cannot provide improved playing experience for beginners making mistakes
Solution Approach 1:
The layout information is designed to be dynamically modifiable while maintaining overall system reliability. The modification unit selectively adjusts specific regions based on detected mistakes without fundamentally altering the stable core system, allowing adaptive improvement while preserving reliable sound generation and basic functionality

AI summary
A musical instrument includes memory that stores layout information defining regions arranged on a predetermined virtual plane, and a position sensor that detects the position coordinates on the virtual plane of a music playing member that can be held by a player. First, it is determined whether the position coordinates of the music playing member belong to a region arranged on the virtual plane based on the layout information, at a timing at which a specific music playing operations is made. Herein, in a case of having determined as belonging to a region, the generation of sound of a musical note corresponding to this region is instructed, in a case of having determined as not belonging to a region, the layout information stored in the memory is modified in order to modify this region so as to include the position coordinates of the music playing member.
