Virtual Instrument Layout Adjustment via Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional musical performance devices lack the ability to change virtual instrument set layout information intuitively during performance, limiting the variety of musical experiences.
Innovation Solution
A musical performance device with a position detecting section, storage for layout information, a mode specifying section, and a position changing section that allows for intuitive adjustment of virtual instrument set layouts by detecting the position of performance components and changing their positions based on detected coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a switch for layout setting is provided in the main body of the musical instrument gaming device to change layout information, then the layout information can be changed, but the instrument player cannot change the layout information by an intuitive operation while performing music
Solution Approach 1:
The system uses the musical performance component itself to perform the layout adjustment function. When the component is operated in position change mode, it automatically detects its own position coordinates and uses this information to adjust the layout, eliminating the need for separate control switches or adjustment screens.
Solution Approach 2:
The musical performance component serves dual functions: it can be operated in musical performance mode to generate musical sounds, and in position change mode to adjust layout information. This multi-functionality eliminates the need for separate control mechanisms.
2Adaptability or versatility
If the instrument player operates switches while viewing an adjustment screen to change layout information, then the layout can be adjusted, but the player cannot perform music simultaneously
Solution Approach 1:
The system pre-establishes the association between position coordinates and layout areas before performance. During performance, the player simply needs to operate the component within the desired area, and the system automatically retrieves and applies the corresponding layout information from storage, enabling immediate layout changes without interruption.
Solution Approach 2:
The system provides real-time feedback by detecting the position coordinates of the musical performance component and automatically matching them with the corresponding layout areas. This automated feedback loop eliminates the need for manual screen viewing and switch operation.
3Device complexity
If layout information is predetermined and fixed, then the device structure is simple, but the variety of musical performance cannot be increased
Solution Approach 1:
The layout information is stored in a changeable format in the storage section, allowing it to be dynamically adjusted during performance. The system maintains a database of multiple layout configurations that can be selected and modified based on performance needs, balancing structural simplicity with operational flexibility.

AI summary
An object of the present invention is to provide a musical performance device capable of changing layout information, such as information regarding the arrangement of a virtual musical instrument set, by an intuitive operation. In the present invention, when position coordinates detected at a shot timing are within one of the areas of a plurality of virtual pads, a CPU designates a virtual pad in this area as a target of positional change. Then, the CPU determines a position where the virtual pad designated as a target of positional change is placed by this positional change, based on position coordinates detected at shot timings, and changes the position of the virtual pad designated as a target of positional change to the determined position.
