Load Sensor Gravity Center Detection for Music Progression Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dance game apparatuses do not allow users to control music progression using their whole body movements, limiting the ability to feel like they are performing music and failing to adequately reflect whole-body movements in the game.
Innovation Solution
A music performance program that utilizes a load measuring device with a load sensor to track the user's body center of gravity, determining movement patterns and speeds to control music reproduction, including volume and tempo adjustments based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user steps on predetermined stepping positions in accordance with music progress, then the user can express rhythm, but the user cannot control music progression using whole body movements
Solution Approach 1:
The patent replaces the mechanical stepping platform system with a load sensor-based gravity center detection system. Instead of requiring users to step on predetermined positions, the system uses load sensors to detect the user's gravity center position and movement patterns, substituting mechanical position verification with sensor-based motion analysis to enable more natural whole-body control.
Solution Approach 2:
The load sensor system serves multiple functions: it detects gravity center position, measures movement speed, and determines movement patterns. This multi-functional detection approach allows the system to control various aspects of music reproduction (tempo, volume, progression) based on diverse body movements, enhancing both ease of operation and adaptability.
2Adaptability or versatility
If only stepping platforms are used to detect user input, then the device complexity is low, but the user cannot reflect whole body movements in the game
Solution Approach 1:
The patent merges the detection function into the existing music performance apparatus structure by integrating load sensors with the gravity center detection mechanism. This combination allows the system to capture whole-body movements without adding separate complex detection devices, as the load sensors work in conjunction with the existing control system to process movement data for music reproduction.
3Reliability
If the user moves their body to control music, then the musical experience is enhanced, but the measurement precision of body movement must be high
Solution Approach 1:
The system continuously monitors the user's gravity center position and movement patterns through load sensors, providing real-time feedback to control music reproduction. The determination unit analyzes the detected movement data and adjusts music playback accordingly, creating a responsive feedback loop that enhances musical experience while maintaining reliable control through continuous measurement and adaptation.

AI summary
A game apparatus repeatedly calculates a gravity center position based on load values detected by respective load sensors of a load controller. The game apparatus sequentially reproduces each of measures of a musical piece by reproducing a next measure when the gravity center position moves beyond a reference line. In this case, the game apparatus changes a reproduction sound volume in accordance with the gravity center position and a speed at which the gravity center moves.
