Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing game processing systems using inertial sensors struggle to accurately differentiate between intended and unintentional player inputs, leading to potential misinterpretation of player actions.

Innovation Solution

The system introduces a suspension period after detecting an input in a secondary direction, allowing the player to correct their motion towards the intended first direction, thereby preventing unintentional operations from affecting game processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a threshold is adjusted to easily determine direction input toward the correct-answer direction, then the ease of operation is improved, but unintentional operations may be mistakenly detected

Engineering Contradiction:

Improveease of direction inputVSAvoidaccuracy of input detection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary determination of motion direction before executing game processing. By pre-determining whether the input device was moved in the first direction (correct-answer direction) or second direction (incorrect direction), the system can prevent unintentional operations from being reflected in game processing while maintaining easy operation through the suspension period mechanism

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the input device is moved in the second direction, then the game processing should be prevented from executing, but the player may intend to move in the first direction

Engineering Contradiction:

Improveaccuracy of input detectionVSAvoidplayer responsiveness

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system preliminarily determines the motion direction and sets a suspension period before finalizing game processing. During this suspension period, the system waits to see if the player corrects their motion toward the first direction. This preliminary determination mechanism ensures accurate input detection while allowing players to correct unintentional motions without delay

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the input processing state based on real-time motion detection. When motion in the second direction is detected, the system transitions to a suspension state where it continues monitoring for corrective motion in the first direction. This dynamic response allows the system to adapt to player intentions while maintaining reliable input detection

Inventive Principle:

Principle #15Dynamics

AI summary

During execution of a game, first-type processing is executed if it is determined that an input device has been moved in a first direction at a timing when a predetermined condition is satisfied during execution of the game, on the basis of operation data including at least data based on an output of an inertial sensor. In a case where, on the basis of the operation data, it is determined that the input device has been moved in a second direction at a timing when the predetermined condition is satisfied, if it is further determined that the input device has been moved in the first direction during a predetermined suspension period, the first-type processing is executed. If it is determined that the input device has not been moved in the first direction during the predetermined suspension period, second-type processing is executed after the predetermined suspension period has elapsed.
