Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Game devices with depression operation receiving means, such as mat-type controllers, face challenges in accurately detecting player position changes, leading to difficulties in maintaining accurate information due to displacement of the player's standing position during gameplay.

Innovation Solution

Incorporating judgment subject area changing means that adjust the position of the judgment area based on the player's depressed position, ensuring accurate game processing and feedback through display control mechanisms that adjust the game character's position relative to the player's stance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the judgment subject area is kept fixed during game play, then the game processing can be executed stably, but the player's standing position displacement causes the foot position to go outside the judgment subject area, making accurate information detection difficult

Engineering Contradiction:

Improvegame processing stabilityVSAvoidfoot position detection accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The judgment subject area is changed from a fixed position to a dynamic position that moves together with the player's standing position. The detection means tracks the player's standing position and adjusts the judgment subject area accordingly, ensuring the area remains aligned with the player's feet even as they move during gameplay.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system continuously monitors the player's standing position through the depression operation receiving means and uses this feedback information to adjust the judgment subject area position. This closed-loop feedback mechanism ensures the judgment area stays synchronized with the player's actual position throughout the game.

Inventive Principle:

Principle #23Feedback

2Measurement precision

If the judgment subject area is adjusted to follow the player's standing position, then accurate foot position detection is maintained, but the system complexity increases due to the need for continuous position tracking and adjustment

Engineering Contradiction:

Improvefoot position detection accuracyVSAvoidposition tracking system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The depression operation receiving means serves dual functions: it both detects the player's foot depression actions and tracks the player's standing position. By making the position detection capability inherent to the existing depression receiving means, the system avoids adding separate tracking hardware, thereby reducing overall system complexity while maintaining detection accuracy.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A game device is provided. The game device includes a depression operation receiver that receives a depression operation of a player and outputs information regarding a position depressed by the player; a depressed position acquirer that acquires the position depressed by the player based on the information output; a controller that determines whether the position depressed by the player is included within a judgment subject area, executes game processing based on a result of the determination, and changes, in a case where it is determined that the position depressed by the player is not included within the judgment subject area, a position of the judgment subject area based on the position depressed by the player.
