Touch Screen Unlocking via Icon Magnification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen unlocking methods, such as slide-to-unlock, face challenges in accurately determining sliding paths and forces, leading to user experience issues due to potential mistakes.
Innovation Solution
A touch screen unlocking method involving the display of pairs of matching icons, where tapping one icon magnifies the other, allowing a second tap to unlock the screen, with customizable icons and adjustable time for the second tap operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If slide-to-unlock method is used, then unlocking function is provided, but sliding path length and force cannot be accurately controlled
Solution Approach 1:
The patent replaces the mechanical slide-to-unlock operation with a touch-based icon selection system. Instead of requiring precise sliding path control and force detection, the system uses graphical icons that users can easily tap and select, substituting the complex mechanical detection system with a simpler visual interface system.
Solution Approach 2:
The patent changes the operational parameters from continuous sliding motion with variable force to discrete icon selection with tap gestures. This parameter change transforms the unlocking mechanism from one requiring precise path and force control to one based on simple visual selection and confirmation taps.
2Measurement precision
If two-point touch unlocking is implemented, then operation accuracy is improved, but device complexity increases
Solution Approach 1:
The patent uses visual copies or representations of information (icons) to enable accurate unlocking operations. The icons serve as visual copies of the underlying data or functions, allowing users to interact with simplified visual representations rather than complex technical mechanisms, thereby maintaining accuracy while reducing perceived complexity.

AI summary
A touch screen unlocking method comprises displaying a plurality of icons on an unlocking interface, among which at least two icons can be arranged to match with each other; after a user taps one of the matched icons, amplifying and displaying the other icon; when the user taps the amplified and displayed icon area, unlocking the touch screen. According to the present invention, the frequency of mistakes by the user can be reduced, and the user experience can be improved.
