Watch Face Hand-Position Unlocking for Secure Smartwatch Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sliding unlocking methods for smart watches are simplistic, affecting user experience, especially as the devices store increasing amounts of private data.
Innovation Solution
A screen unlocking method that utilizes the position of hands on a watch face to determine a preset unlocking condition, allowing users to input a specific unlocking track that matches the condition to unlock the device, incorporating features like intervals and included angles between hands to enhance diversity and interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sliding or double tapping unlocking methods are used, then the device is easy to operate, but security and privacy protection are insufficient
Solution Approach 1:
The patent changes the unlocking parameters from simple gestures (sliding, double tapping) to complex hand position patterns on the watch face. By utilizing the positions and intervals of multiple hands (hour hand, minute hand, second hand) as unlocking parameters, the system increases security while maintaining ease of operation through intuitive hand-based interaction.
Solution Approach 2:
The patent transitions from two-dimensional gesture recognition (sliding on screen) to three-dimensional spatial reasoning by incorporating the circular arrangement of watch hands. The unlocking mechanism considers radial positions, angular intervals, and rotational relationships of hands, adding a new dimension of complexity that enhances security without sacrificing usability.
2Reliability
If simple unlocking methods are used, then user experience is maintained, but protection of private data is compromised
Solution Approach 1:
The system uses the device's own display interface (watch face) as the unlocking mechanism. The hands that naturally move and display time information are repurposed as the unlocking elements, eliminating the need for separate biometric sensors or additional hardware. This self-service approach enhances data protection while avoiding increased device complexity.
Solution Approach 2:
The watch face serves multiple functions: displaying time information and providing security authentication. The hands that indicate time also serve as the unlocking pattern, allowing the same interface elements to fulfill both informational and security roles, thereby protecting private data without adding device complexity.
3Reliability
If hand position-based unlocking is implemented, then security is enhanced, but the unlocking process becomes more complex
Solution Approach 1:
The unlocking mechanism leverages the dynamic movement of watch hands as they naturally progress through their cycles. The system captures hand positions at specific moments during their movement, using the inherent dynamics of timekeeping to create security patterns. This dynamic approach enhances security while keeping the unlocking process simple and automatic.
Solution Approach 2:
The system provides visual feedback by displaying the current hand positions and comparing them against the required unlocking pattern. This feedback mechanism guides the user through the unlocking process, making the complex hand position requirements transparent and manageable, thereby enhancing security without making the process overly complicated.
Data Source
AI summary
This application discloses a screen unlocking method and apparatus, and an electronic device, and pertains to the technical field of terminal devices. The screen unlocking method includes: obtaining a first position of a first hand in a case that a target interface is displayed on a screen of an electronic device, where the target interface includes the first hand; determining a first preset unlocking condition corresponding to the first position; receiving an unlocking input performed by a user; and unlocking the electronic device in response to the unlocking input in a case that the unlocking input matches the first preset unlocking condition.
