Game Machine Foot-Lifting Guidance via Contact State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music games primarily focus on advising and evaluating stepping actions, neglecting the importance of transitioning from a contacting to a non-contacting state, which can enhance the beauty and interest of dance steps by guiding players to lift their feet appropriately.
Innovation Solution
A game machine equipped with a detection device to monitor contacting and non-contacting states, an advisory device to suggest timely transitions between these states, and an evaluation device to assess the actual timing of these transitions, allowing for more expressive and beautiful dance moves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the game machine only advises stepping actions (contacting state), then the evaluation system is simple, but the dance beauty and player satisfaction are insufficient
Solution Approach 1:
The patent segments the dance action evaluation into two distinct phases: stepping action (contacting state) and lifting action (non-contacting state). By dividing the continuous dance movement into discrete evaluable segments, the system can provide targeted feedback for each phase without overwhelming complexity, thereby enhancing dance beauty while managing system complexity.
Solution Approach 2:
The game machine provides preliminary advice not only for when to step on the target position but also for when to lift the foot from the target position. This preliminary guidance on both contacting and non-contacting states allows players to plan their dance movements in advance, improving dance beauty and player satisfaction.
2Ease of operation
If the game machine evaluates only stepping timing, then the evaluation process is simple, but the player satisfaction and game interest are limited
Solution Approach 1:
The patent implements a dual feedback system that provides evaluation results for both stepping actions (contacting state) and lifting actions (non-contacting state). This comprehensive feedback mechanism enhances player satisfaction by recognizing and rewarding complete dance movements, while the automated detection system manages the complexity of monitoring multiple states.
Solution Approach 2:
The game machine uses an intermediary evaluation system that translates complex sensor data about foot position and contact states into simple, understandable feedback for players. This intermediary layer handles the difficulty of detecting and measuring multiple contact states while presenting simplified information to players, thereby increasing player satisfaction without proportionally increasing perceived complexity.
3Ease of operation
If the game focuses on stepping accuracy, then the game mechanics are simple, but the dance expressiveness is reduced
Solution Approach 1:
The patent transforms the static evaluation of only stepping accuracy into a dynamic evaluation system that considers both stepping (contacting) and lifting (non-contacting) actions. This dynamic approach allows the guidance system to adapt to different phases of dance movement, enhancing dance expressiveness while the structured evaluation framework manages system complexity.

AI summary
Provided is a game machine capable of providing guidance so that, at an appropriate timing, the player performs the action of changing from a contacting state in which he/she is contacting a predetermined region to a non-contacting state in which such contact is not performed. The game machine provides a dance game for providing guidance about the performance timing of a dance step, and evaluating the actual step performance timing. The game machine comprises a stage sensor that detects a contacting state in which a foot of a player is contacting a treading surface of the stage, and detects a non-contacting state where such contact is not performed. The game machine also provides guidance about the time of a foot-lifting action as the step performance timing, and evaluates the time as the actual step performance timing, so that a foot-lifting action changing functions as the dance step.
