Portable Device Anti-Oversleeping via G-Sensor and Eye Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alarm clocks are easily turned off while still in bed, leading to oversleeping, as users can silence them without fully waking up.
Innovation Solution
A portable electronic device combines a g-sensor and image capturing module to require users to get up and open their eyes for human-eye recognition, ensuring the alarm cannot be turned off until this is achieved, thereby preventing oversleeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the alarm clock is made simple and convenient to operate, then ease of operation is improved, but the user may easily turn it off without opening eyes leading to oversleeping
Solution Approach 1:
The system changes the operational parameters required to silence the alarm. Instead of allowing simple button presses, it requires specific physical actions (tilting the device, making circular motions) that can only be performed when the user is awake and active, thus changing the parameter from 'easy button press' to 'complex physical interaction'
Solution Approach 2:
The patent replaces traditional mechanical button-press operation with sensor-based detection systems (accelerometer, gyroscope, image capturing module) that detect user actions. This substitution allows the system to verify the user is truly awake by detecting circular hand motions or eye opening, rather than relying on simple mechanical input
2Reliability
If complicated alarm clock functions are added to prevent oversleeping, then reliability of waking user is improved, but device complexity increases and extra cost is incurred
Solution Approach 1:
The patent makes the mobile phone serve multiple functions: it acts as both a standard communication device and an advanced alarm clock with anti-oversleep features. By utilizing existing mobile phone components (accelerometer, gyroscope, image capturing module, touchscreen) for alarm functions, it avoids the need for a separate dedicated alarm clock device, thus reducing overall device complexity while maintaining high reliability
Solution Approach 2:
The system uses the mobile phone's own built-in sensors and components to perform alarm verification functions. The accelerometer and gyroscope detect device orientation and motion, while the image capturing module verifies eye opening, allowing the phone to self-verify the user is awake without requiring external devices or complex additional hardware

Function Achieved in This Case
Effectively prevents oversleeping by ensuring the user is fully awake before the alarm can be silenced, leveraging the g-sensor to detect device slant and the image capturing module for human-eye recognition, ensuring the alarm is only turned off after successful recognition.
Implementation Method 1
the g-sensor detects whether the portable electronic device is slanted
Implementation Method 2
the image capturing module performs human-eye recognition

AI summary
An operation method for a portable electronic device is provided. The portable electronic device includes a micro-controller, a ringing module, a g-sensor and an image capturing module. The operation method includes the following steps. When the ringing module is started up at a pre-set time, the g-sensor detects whether the portable electronic device is slanted. If the portable electronic device is slanted, the micro-controller enables the image capturing module to perform human-eye recognition. If human-eye recognition is performed successfully and lasts for a specific period, the micro-controller disables the ringing module.
