Gesture-Based Unlocking via Dynamic State Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-sensitive displays on portable devices often lead to unintentional activation or deactivation of functions due to accidental contact, and current unlocking methods, such as button combinations or passwords, are cumbersome and reduce user-friendly interaction.
Innovation Solution
A method for controlling touch-sensitive displays that involves detecting specific gestures or movements on the screen to transition between locked and unlocked states, using visual cues and sensory feedback to guide the user through the unlocking process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional unlocking methods (button combinations or passwords) are used, then device security is maintained, but user ease of operation deteriorates due to cumbersome procedures
Solution Approach 1:
The patent replaces traditional mechanical unlocking methods (physical button combinations) and cognitive unlocking methods (password entry) with a gesture-based control system. The system detects touch gestures on the touch-sensitive display and transitions between locked and unlocked states based on recognized gesture patterns, eliminating the need for physical button sequences or memorized passwords.
Solution Approach 2:
The system allows the device to automatically recognize and respond to gesture inputs without requiring the user to manually navigate through complex unlocking procedures. The gesture recognition system autonomously determines user intent and executes the appropriate state transition, making the unlocking process as simple as performing a natural touch gesture on the screen.
2Ease of operation
If touch-sensitive displays are used to improve user interaction, then ease of operation improves, but accidental contact leading to unintentional activation increases
Solution Approach 1:
The system introduces dynamic state transitions based on gesture recognition. Instead of static button presses that can be accidentally triggered, the system requires deliberate gesture patterns (such as sliding, tapping, or specific motion sequences) to transition between locked and unlocked states. The system dynamically evaluates touch inputs against predefined gesture criteria, allowing legitimate user gestures while filtering out accidental contacts.
3Ease of operation
If gesture-based unlocking is implemented to simplify the unlocking process, then ease of operation improves, but the precision of gesture detection becomes critical
Solution Approach 1:
The system incorporates feedback mechanisms to confirm gesture recognition and state transitions. When a gesture is detected, the system evaluates it against predefined criteria and provides feedback (such as visual or haptic confirmation) to the user. This feedback loop allows the system to adjust its detection thresholds and ensures that only deliberate, recognized gestures trigger state changes, maintaining both simplicity and accuracy.

AI summary
A device with a touch-sensitive display may be unlocked via gestures performed on the touch-sensitive display. The device is unlocked if contact with the display corresponds to a predefined gesture for unlocking the device. The device displays one or more unlock images with respect to which the predefined gesture is to be performed in order to unlock the device. The performance of the predefined gesture with respect to the unlock image may include moving the unlock image to a predefined location and/or moving the unlock image along a predefined path. The device may also display visual cues of the predefined gesture on the touch screen to remind a user of the gesture.
