Game Device Posture Comparison for Dance Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game devices lack a comprehensive mechanism to assist players in identifying and improving their dance skills, particularly in dance games, by providing detailed feedback on posture and movement accuracy.
Innovation Solution
A game device that acquires and compares player posture data with exemplary model postures at reference times, allowing for real-time feedback on posture alignment and movement synchronization, using a combination of photography and infrared sensors to detect player posture and output corrective feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple comparison operations are performed to provide detailed feedback on player posture, then the measurement precision and feedback quality improve, but the device complexity and computational load increase
Solution Approach 1:
The comparison mechanism is segmented into multiple independent comparison units, each responsible for comparing the player's posture with a specific reference posture (exemplary model posture, different postures at reference time, or postures at different times). This segmentation allows the system to perform comprehensive comparisons while maintaining modular architecture, where each unit can be independently implemented and managed, thus resolving the contradiction between comprehensive measurement and system complexity.
Solution Approach 2:
The system extends the comparison process from a single reference point to multiple dimensions by introducing temporal dimensions (comparing at reference time vs. different times) and posture variation dimensions (comparing with exemplary model vs. different postures). This multi-dimensional approach enables comprehensive feedback without requiring a single complex comparison mechanism, as each dimension can be handled by dedicated comparison units.
2Loss of information
If comprehensive posture comparison is implemented to identify all dance weaknesses, then the feedback quality improves, but the processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-defining multiple reference postures (exemplary model postures, different postures at reference time, and postures at different times) before the actual comparison process. This preparation allows the comparison units to directly compare player posture against pre-established references without requiring complex real-time calculations, thus reducing processing time while maintaining comprehensive feedback coverage.
Solution Approach 2:
Each comparison unit independently processes its specific comparison task without requiring sequential processing or coordination with other units. The system architecture allows parallel execution of multiple comparison operations, where each unit self-manages its comparison process and generates feedback independently, thereby reducing total processing time while maintaining comprehensive feedback coverage.

AI summary
A game device in which a first comparison unit compares an exemplary model posture (posture that is supposed to be adopted by a player) at a reference time and a posture of the player indicated by posture data acquired by a posture data acquiring unit at a compared time. A second comparison unit executes at least one of: a comparison between a different posture from the exemplary model posture at the reference time and the posture of the player indicated by the posture data acquired at the compared time; and a comparison between the exemplary model posture at the reference time and a different posture from the posture of the player indicated by the posture data acquired at the compared time. An output control unit causes an output based on a comparison between results from the first and second comparison units.
