Virtual Instrument Layout Adjustment for Player Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional musical performance devices do not adapt the arrangement of virtual musical instruments to the player's position, leading to potentially uncomfortable playing positions.
Innovation Solution
A musical performance device with a position detecting section, storage for layout information, and a changing mechanism that adjusts the virtual instrument arrangement based on the player's position, allowing for dynamic reconfiguration of the virtual instrument set.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the layout information of the virtual musical instrument set is predetermined and fixed, then the device structure is simple and easy to control, but the instrument player is forced to play in an uncomfortable position when repositioning
Solution Approach 1:
The patent applies the dynamics principle by making the virtual instrument layout adjustable rather than fixed. The changing section dynamically repositions the virtual musical instrument set on the display based on the player's detected position, allowing the layout to adapt from a static predetermined arrangement to a dynamic configuration that follows the player's movements, thereby resolving the contradiction between operational comfort and device complexity.
Solution Approach 2:
The patent implements feedback by using the position detecting section to continuously monitor the player's position and feeding this information back to the changing section. This closed-loop system adjusts the virtual instrument layout in response to the player's position, ensuring the instrument set remains optimally positioned for comfortable play while maintaining relatively simple device architecture through automated feedback-driven adjustment.
2Adaptability or versatility
If the virtual musical instrument set arrangement is fixed, then the device is easier to manufacture and control, but the player cannot maintain a comfortable position when moving
Solution Approach 1:
The patent applies universality by designing a system where the position detecting section and changing section work together to provide position-adaptive functionality for any player position. Rather than creating separate fixed arrangements for different positions, the system provides a single universal mechanism that automatically adapts the virtual instrument layout to match the player's location, enhancing adaptability while keeping the overall device structure relatively simple.
Solution Approach 2:
The system implements self-service by having the position detecting section automatically detect the player's position and the changing section automatically adjust the virtual instrument layout without requiring manual intervention. This automated self-adjustment mechanism provides position adaptation functionality while avoiding the complexity of manual configuration systems, allowing the device to serve itself in adapting to different playing positions.

AI summary
An object of the present invention is to provide a musical performance device by which the arrangement of a virtual musical instrument set is suitably changed based on the position of the instrument player, and whereby the instrument player need not play in an uncomfortable position. In the present invention, set layout information includes standard set layout information that serves as reference for the arrangement of a plurality of virtual pads, and a CPU judges whether an operation to form a square has been performed with a pair of drumstick sections. When judged that this operation has been performed, the CPU uniformly adjusts the arrangement of the virtual pads based on preset position coordinates on a captured image plane corresponding to the standard set layout information and the position coordinates of the drumstick sections on the captured image plane at the time of the operation to form a square.
