Touch-Sensitive Surface Gesture Navigation with Protected App Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen technologies lack efficient mechanisms to dynamically switch between user interfaces based on specific input criteria, such as navigation gestures, leading to inconsistent user experiences.
Innovation Solution
A device with a touch-sensitive surface that detects inputs meeting predefined criteria, such as navigation gestures, to determine whether to switch between user interfaces, ensuring protected applications remain visible or hidden accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system allows navigation gestures to switch between user interfaces, then ease of operation is improved, but reliability deteriorates because protected applications may be accidentally exited
Solution Approach 1:
The patent applies local quality by implementing different response behaviors for different regions of the touch-sensitive surface. Edge regions are designated for navigation gestures that can exit applications, while central regions preserve applications. This spatial differentiation allows the system to provide easy navigation when needed while protecting applications from accidental exits, resolving the contradiction between ease of operation and reliability.
2Reliability
If the system implements application protection against navigation gestures, then reliability is improved, but ease of operation deteriorates due to inconsistent user experience
Solution Approach 1:
The patent implements dynamics by making the system's response to navigation gestures context-dependent rather than static. The system dynamically evaluates whether an application is protected based on its current state and the gesture's location, allowing it to adapt between protecting applications and enabling navigation. This dynamic behavior ensures consistent user experience by providing predictable protection while maintaining ease of operation for intended navigation actions.
3Ease of operation
If the system detects navigation gestures crossing boundary regions, then ease of operation is improved for navigation, but device complexity increases due to additional detection criteria
Solution Approach 1:
The patent applies segmentation by dividing the touch-sensitive surface into distinct functional regions: edge regions for navigation gestures and central regions for application interaction. This segmentation simplifies the detection mechanism by using clear spatial boundaries to determine gesture intent, reducing the complexity of the detection algorithm while improving ease of operation for navigation tasks.
