Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch-sensitive displays typically provide only binary visual feedback, limiting the user experience by not simulating varying touch pressures, which can result in a less intuitive and richer interaction.
Innovation Solution
The method involves detecting multiple measures of touch pressure and displaying corresponding images on the display, using optical, capacitive, or resistive mechanisms to simulate different touch pressures, allowing for a more nuanced visual response, including changes in image appearance and sound, based on the detected pressure and object characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If binary visual feedback is used to simulate touch response, then the system is simple to implement, but the user experience is limited and less intuitive
Solution Approach 1:
The patent applies dynamics by transitioning from static binary button states to dynamic visual representations that continuously adapt to varying touch pressure levels. The system detects multiple pressure measurements and dynamically adjusts the displayed image to reflect the current pressure state, creating a responsive and intuitive user experience without requiring complex hardware modifications
Solution Approach 2:
The patent utilizes parameter changes by mapping multiple touch pressure parameters to corresponding visual display parameters. The system detects varying pressure levels and changes the displayed image parameters (such as button depression depth, color intensity, or texture) to match the detected pressure, thereby enriching user feedback while maintaining system simplicity
2Loss of information
If multiple measures of touch pressure are detected and displayed, then visual feedback becomes richer and more realistic, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the touch pressure detection into multiple discrete measurement levels. Instead of treating touch as a single binary state, the system segments the pressure range into multiple levels (e.g., light touch, medium pressure, heavy press) and assigns distinct visual representations to each level, preserving touch pressure information while managing system complexity through structured categorization
3Reliability
If binary button states are used, then the interface is simple to implement, but the simulation of physical touch response is inadequate
Solution Approach 1:
The patent applies copying by creating visual copies of physical button states that accurately represent different pressure levels. The system generates multiple image variants corresponding to different touch pressures and displays the appropriate copy based on detected pressure, thereby improving touch simulation accuracy while avoiding the need for complex physical mechanisms
