Touchscreen Unlock Image Brightness Progress Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens on portable devices often unintentionally activate or deactivate functions due to accidental contact, leading to cumbersome unlocking procedures that reduce user convenience and ease of use.
Innovation Solution
Implementing a method where the device detects progress towards satisfying a user input condition to transition between user interface states by changing the optical intensity of associated objects, allowing for intuitive gestures to unlock the device, providing sensory feedback on progress and simplifying the unlocking process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional unlocking procedures (button combinations, passwords) are used, then device security is maintained, but ease of operation deteriorates due to complexity and burden
Solution Approach 1:
The patent replaces traditional mechanical unlocking methods (physical buttons, memorized passwords) with a touch-sensitive display-based gesture recognition system. The unlock image and gesture interaction eliminate the need for memorizing codes or pressing specific button combinations, significantly simplifying the unlocking procedure while maintaining security through pattern recognition.
Solution Approach 2:
The system automatically detects and responds to user gestures on the touch screen without requiring manual intervention for code entry or button sequencing. The gesture recognition system self-evaluates the user's input pattern and automatically transitions the device state, eliminating the burden of remembering and recalling complex unlocking sequences.
2Ease of operation
If touch screens are used for user interaction, then ease of operation improves, but reliability deteriorates due to unintentional activation from accidental contact
Solution Approach 1:
The system displays an unlock image in advance that guides the user on the required gesture pattern before activation occurs. This preliminary visual instruction ensures that only intentional gestures matching the displayed pattern will trigger state transitions, preventing accidental activations while maintaining the accessibility benefits of touch screen interaction.
Solution Approach 2:
The system provides visual feedback through the unlock image that changes or animates based on the user's gesture progress. This feedback mechanism helps users understand what gesture is expected and confirms when the correct pattern is detected, distinguishing intentional gestures from accidental contacts while maintaining intuitive operation.
3Ease of operation
If sensory feedback is added to indicate progress towards unlocking, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent utilizes optical intensity changes (brightness, contrast, color transitions) of the unlock image to indicate progress towards unlocking. By modifying the visual properties of the unlock image based on gesture completion percentage, the system provides clear sensory feedback without adding separate indicator components, maintaining simplicity while enhancing user awareness.

AI summary
In some embodiments of the invention, a graphical user interface in an electronic device includes one or more user-interface objects associated with a second user-interface state. While the device is in a first user-interface state, the one or more objects transition in optical intensity to indicate progress towards satisfaction of a user input condition needed to transition to the second user-interface state.
