Smart Watch Heart Rate Sensor Lock-Screen Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart watches lack automatic lock-screen functionality, leading to potential security breaches when users forget to manually lock the device, especially after introducing payment functions, which can result in unauthorized access and information security issues.
Innovation Solution
A method and system utilizing a heart rate sensor to determine if a smart watch is unclasped, automatically entering a password-lock-screen mode when unclasped, and remaining unlocked if still in use, with options for password input types such as pattern or numeric passwords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual lock-screen mode is used, then user can protect information security, but user may forget to lock and lose security protection
Solution Approach 1:
The smart watch automatically detects when it is unclasped and enters lock-screen mode without requiring user intervention. The system monitors its own state through the heart rate sensor and autonomously executes the locking action, eliminating the burden on the user to manually lock the device while maintaining security protection.
Solution Approach 2:
The system performs the lock-action in advance before any potential unauthorized access can occur. When the unclasped state is detected, the lock-screen mode is immediately activated, preventing any possible security breaches before they can happen.
2Reliability
If automatic lock based on unclasped detection is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The heart rate sensor serves multiple functions: it monitors heart rate for health tracking purposes and simultaneously detects the unclasped state for security purposes. By making the sensor multi-functional, the system avoids adding separate dedicated sensors, thereby limiting the increase in device complexity while achieving automatic security protection.
3Ease of operation
If heart rate sensor continues working, then usability is maintained, but energy consumption increases
Solution Approach 1:
The heart rate sensor dynamically adjusts its operating state based on the detected condition. When the smart watch is unclasped, the sensor stops working to save energy. When the watch is clasped and usable, the sensor resumes operation to maintain health monitoring and usability. This dynamic state change optimizes the balance between energy consumption and functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user experience by eliminating the need for manual locking and mitigates security risks by automatically securing the device when taken off, while maintaining usability when worn.
Implementation Method 1
The heart rate sensor may be a photoelectric heart rate sensor

AI summary
Smart watches and associated systems and methods thereof for lock-screen management are disclosed. A smart watch includes a heart rate sensor, and a method for lock-screen management of the smart watch includes: reading, by the heart rate sensor, a heart rate; determining based on the heart rate whether the smart watch has been taken off by the user, and if yes, stopping the heart rate sensor from working and entering by the smart watch a password-lock-screen mode. Thus, using the method according to the present disclosure can improve the information security on the smart watch.
