Motion-Based Screen Unlock for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack intuitive and secure methods for unlocking screens, particularly in scenarios where personal and sensitive information is stored, necessitating the development of enhanced security measures that balance convenience and security.
Innovation Solution
A mobile terminal equipped with a motion measure unit, motion pattern storage, and a controller that measures and compares user-defined motion patterns to unlock the screen, potentially combining this with touch patterns and password authentication for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional password or touch pattern unlock methods are used, then security of personal information is maintained, but user convenience and intuitiveness are reduced
Solution Approach 1:
The patent replaces traditional mechanical input methods (typing passwords on keyboards or drawing touch patterns on screens) with motion-based recognition. The motion measure unit captures physical movements of the terminal device, and the controller compares these motions against stored motion patterns to authenticate users. This substitution eliminates the need for deliberate manual input while maintaining security through motion analysis.
Solution Approach 2:
The system performs automatic motion capture and comparison without requiring explicit user actions to input credentials. The motion measure unit continuously or periodically monitors device motion, and the controller automatically compares captured motions against stored patterns, enabling the system to service itself in the authentication process rather than requiring manual user input.
2Ease of operation
If motion-based unlock is implemented, then user convenience is improved, but device complexity increases
Solution Approach 1:
The motion measure unit, which may be part of an existing sensor system, serves multiple functions: it captures motion data for unlock authentication, monitors device usage patterns, and provides data for comparing against stored motion patterns. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity despite adding motion-based unlock capability.

AI summary
A mobile terminal and a method perform screen unlock based on a motion. The mobile terminal includes a motion measure unit, a motion pattern storage, and a controller. The motion measure unit measures a first motion pattern of the mobile terminal. The motion pattern storage stores a second motion pattern set for the mobile terminal. When the first motion pattern of the mobile terminal measured by the motion measure unit coincides with the second motion pattern stored in the motion pattern storage, the controller executes a screen unlock of the mobile terminal.
