Game Program Pausing Time Count via Facial Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tooth brushing game applications continue counting time even when the user is not actively brushing their teeth, leading to discouragement due to incomplete game progress, especially in situations like a child being helped by an adult.
Innovation Solution
A game program that captures user images, detects facial areas and toothbrush movements, and stops counting time only when the mouth area is not set, allowing for temporary interruptions without penalizing the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the time limit counting continues even when the user is not brushing teeth, then the game evaluation can be enhanced through continuous movement, but the user may be discouraged when temporary interruptions occur (e.g., adult helping child)
Solution Approach 1:
The system continuously monitors whether the user's face is detected in the camera view and provides feedback by pausing or continuing the time count accordingly. This feedback mechanism allows the system to adapt to the user's actual brushing state, pausing during interruptions (improving convenience) while maintaining productivity tracking when brushing occurs.
Solution Approach 2:
The time counting mechanism dynamically adjusts its state based on real-time face detection. The system transitions between counting and pausing states depending on whether the user is present and brushing, allowing flexible adaptation to varying usage scenarios without fixed rigid timing rules.
2Ease of operation
If the time counting stops when the user is not brushing, then user convenience is improved during interruptions, but the game evaluation accuracy may be reduced
Solution Approach 1:
The system uses face detection as continuous feedback to determine when to pause or continue counting. This ensures that time is only counted when the user is actually present and brushing, maintaining evaluation accuracy while automatically accommodating interruptions without user intervention.
Solution Approach 2:
The system automatically detects and responds to user presence or absence without requiring manual input. The face detection mechanism enables the system to self-adjust the counting state, eliminating the need for users to manually pause or resume the game during interruptions.
3Ease of operation
If face detection is used to control time counting, then user convenience is improved by allowing natural interruptions, but the device complexity increases due to camera and detection algorithms
Solution Approach 1:
The camera serves multiple functions: it captures the user's face for presence detection, monitors brushing movements for evaluation, and provides visual feedback. This multi-functionality reduces the need for separate sensors or detection devices, thereby limiting the increase in device complexity while achieving improved user convenience.

AI summary
A tooth brushing game includes starting counting a time that defines one play of a toothbrush game in response to starting the toothbrush game; capturing an image of a user; setting an area around a mouth by detecting a face area of the user from the captured image and detecting a facial part from the detected face area; detecting movement of an object including a toothbrush and a hand in the area around the mouth; controlling the toothbrush game based on the detected movement of the object; and stopping the counting of the time when the area around the mouth is not set but not stopping the counting when the movement of the object is not detected.
