Virtual Drum Set Layout Switching via Optical Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional musical performance devices lack the ability to quickly and easily change layout information during musical performance, limiting the variety of musical experiences.
Innovation Solution
A musical performance device with a position detecting section, selecting section, judging section, and sound generation instructing section that allows for dynamic selection and emission of different musical tones based on the position of a virtual drumstick on a virtual plane, enabling easy switching between various virtual instrument layouts.
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 and operated, then the layout information can be changed, but changing the layout information during musical performance is troublesome, time consuming and lacks practicality
Solution Approach 1:
The system enables self-service layout switching by automatically detecting the drumstick's position and identifying the target virtual instrument pad, then autonomously switching to the corresponding layout without requiring manual switch operation. The player simply needs to point the drumstick at the desired pad, and the system handles the layout change automatically.
Solution Approach 2:
The patent replaces the mechanical switch system with an optical detection system using a camera to capture the drumstick's position. This substitution eliminates the need for physical switch operation and enables more intuitive, hands-free layout selection through visual recognition and position-based identification.
2Reliability
If layout information is predetermined in the musical instrument gaming device, then the device can function as intended, but the layout information cannot be changed during musical performance, limiting the variety of musical performance
Solution Approach 1:
The system transitions from a static, predetermined layout configuration to a dynamic, changeable layout system. Multiple virtual instrument pads with different layouts can be selected and switched during performance based on the drumstick's position, allowing the musical performance variety to be changed without compromising device function stability.
Solution Approach 2:
The patent implements multi-functionality by enabling a single device to support multiple virtual instrument layouts that can be dynamically selected. The same hardware system can function with different virtual drum set configurations, expanding the device's versatility while maintaining reliable operation through consistent detection and response mechanisms.

AI summary
An object of the present invention is to provide a musical performance device by which layout information, such as information regarding the arrangement of a virtual musical instrument set, can be quickly and easily changed during musical performance and whereby the variety of musical performance can be increased. In the present invention, a CPU identifies a musical tone associated with a virtual pad in an area where the position coordinates of a marker section are located in an image captured by a camera unit section at a shot timing by a drumstick section, and emits the identified musical tone. When the position coordinates of the marker section in an image captured at a shot timing are within the area of a control pad on a virtual plane, the CPU switches processing target set layout information to other set layout information among a plurality of set layout information.
