Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch-based user interfaces face limitations in user manipulation due to complex touch gestures and patterns, and they require releasing a flexible display gripped with both hands to input commands, leading to delayed recognition and reduced convenience.
Innovation Solution
An electronic device with a flexible display that includes a force direction sensing unit and a control unit to sense contact forces, allowing for layer conversion by displaying different screens based on contact direction changes, enabling intuitive and convenient operation with finger contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional touch gestures and patterns are used for user interface manipulation, then the device can recognize user commands, but the manipulation becomes complex and requires users to make complex touch gestures or touch several points to draw complex patterns
Solution Approach 1:
The patent changes the sensing parameter from touch position and gesture pattern recognition to force direction sensing. Instead of requiring users to perform complex touch gestures or draw patterns, the system senses the direction of force applied during a simple touch, converting a complex spatial manipulation problem into a simpler directional sensing problem that enhances ease of operation.
2Adaptability or versatility
If the flexible display is gripped with both hands for form changing, then the display can be manipulated, but the user must release the grip to input touch commands
Solution Approach 1:
The patent merges the grip operation and touch input operation into a single unified interaction. By sensing force direction during the grip itself, the system allows users to perform both form changing and command input simultaneously without releasing the grip, combining two previously separate operations into one seamless action.
3Productivity
If touch gestures or patterns are recognized and executed, then user commands can be processed, but it takes certain time to perform and recognize the gestures
Solution Approach 1:
The patent extracts the essential information needed for command recognition from the complex touch gesture process. Instead of requiring full gesture performance and pattern recognition, the system extracts the force direction parameter at the moment of touch, significantly reducing the time needed to process and recognize user commands while maintaining sufficient information for accurate command identification.
