Solution Overview

Problem

Existing game technologies fail to accurately measure user fatigue, leading to potential continuous gameplay despite fatigue and concentration shortages, as they mix awareness and reaction correctness in success rate indices.

Innovation Solution

A game device and method that measure fatigue by receiving operation instruction information triggered by sound outputs, deriving fatigue levels based on user operations during gameplay, and providing feedback on fatigue levels to encourage rest.

VSEngineering Contradiction Analysis

1Device complexity

If success rate is used as an index mixing awareness and reaction correctness, then game performance evaluation is simplified, but fatigue measurement accuracy deteriorates

Engineering Contradiction:

Improveevaluation system complexityVSAvoidfatigue measurement accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the evaluation into two distinct parts: (1) awareness evaluation based on sound output timing, and (2) reaction correctness evaluation based on operation timing. This segmentation allows separate measurement of each component, enabling accurate fatigue assessment by comparing operation timing across multiple trials without the metrics being conflated in a single success rate index.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces sound output as an intermediary signal that triggers the measurement process. The sound output serves as a standardized stimulus that begins the timing measurement, creating a clear reference point for evaluating both awareness (when the user notices the sound) and reaction (when the user performs the operation). This intermediary enables precise temporal measurement independent of overall success rate.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If figures are displayed for a predetermined time period only, then game flow is maintained, but opportunity for accurate reaction measurement is reduced

Engineering Contradiction:

Improvegame flow efficiencyVSAvoidreaction measurement accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent implements periodic sound outputs at predetermined time intervals during the figure display period. Each sound output initiates a measurement cycle, creating multiple measurement opportunities within the game flow. This periodic action ensures that reactions are measured at consistent intervals, improving measurement accuracy while maintaining the predetermined time structure of the game.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent performs preliminary timing measurement from the moment of sound output before the figure disappears. By starting the measurement clock with the sound output and continuing until the operation is detected, the system captures the complete reaction time window, ensuring accurate measurement even within the constrained predetermined display period.

Inventive Principle:

Principle #10Preliminary action

AI summary

The game device includes a reception unit that is configured to receive instruction information created when a user performs an operation on an input device triggered by a sound output while a game progresses and a derivation unit that is configured to start measuring the degree of fatigue on the basis of the instruction information received by the reception unit and derive the degree of fatigue of the user on the basis of an operation performed by the user during the started measurement of the degree of fatigue.
