Game Machine Upper Body Movement Detection and Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music games primarily focus on lower body movements, limiting the engagement and evaluation of upper body and other body part movements, which can enhance game interest but are challenging to specify and evaluate due to their concurrent nature with lower body movements.
Innovation Solution
A game machine with a computer that detects and evaluates shifting actions of the player's upper body or other body parts, providing advisory timing for these actions as play actions, using a detection device, advisory device, and evaluation device to assess the actual performance timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If movements of the upper half of the body are employed as play actions, then the level of interest in the game is enhanced, but it becomes difficult to specify the movements to be employed as play actions because the upper body moves in conjunction with the lower body and is basically never stationary
Solution Approach 1:
The patent divides the body into distinct segments (upper body and lower body) and independently evaluates their movements. The detection device separately detects upper body movements (such as arm waving, clapping, or head movements) from lower body movements (such as stepping or dancing), allowing each segment to be assessed as an independent play action. This segmentation enables the system to specify and evaluate upper body movements even when they occur concurrently with lower body movements.
Solution Approach 2:
The patent introduces a detection device as an intermediary that captures and analyzes body movements. This device serves as a mediator between the player's physical actions and the game system's evaluation, enabling precise detection of upper body movements by capturing images or video data and analyzing movement patterns. The detection device translates complex, concurrent body movements into distinguishable data that can be evaluated for timing accuracy.
2Difficulty of detecting and measuring
If only lower body movements are commanded as play actions, then the detection and evaluation is simpler, but the level of interest in the game is limited
Solution Approach 1:
The patent creates a universal detection and evaluation system that can handle multiple types of body movements (both upper and lower body) through a single integrated framework. The detection device is designed to capture various movement types, and the evaluation device can assess different play actions using consistent timing evaluation criteria. This multi-functional approach allows the game to incorporate diverse dance movements including arm waving, clapping, head movements, stepping, and dancing, all evaluated within the same system.
Solution Approach 2:
The patent implements a dynamic evaluation system that adapts to different types of movements. The detection device can identify and track various body parts independently, and the evaluation device dynamically determines timing based on the specific movement type being performed. This dynamic approach allows the system to flexibly handle both simple lower body movements and more complex upper body movements, maintaining ease of detection while expanding movement variety.

AI summary
The present invention provides a game machine that is capable of utilizing movements of at least a part of the body of the player as play actions. A game machine provides a dance game that advises of a performance timing at which an action constituting a dance is to be executed, and, evaluates the actual performance timing of that. The game machine includes a camera which detects either a crouching action that causes the head of a player to move lower than a lower-limit position or a return movement that causes the head to move higher than an upper-limit position. The game machine advises of a timing at which such crouching action or the like is to be executed so that the crouching action or the like function as the actions of the dance, and, when such crouching action or the like is detected, evaluates the actual timing of that.
