Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch-based user interfaces for small electronic devices, such as smartphones and tablets, face limitations in accurately distinguishing between single and multiple touches, leading to inconvenient operation during tasks like gaming and web surfing, as they primarily rely on touch time period without considering intensity, area, and pressure variations.
Innovation Solution
A system and method that recognizes single and multiple touches on a touch panel by sensing pressure magnitude, area, and time period, allowing for distinct actions based on predetermined conditions, enabling more precise control through the differentiation of single and multiple touch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch time period is used as the only parameter for touch input recognition, then the system is simple to operate, but the precision of distinguishing single touch from multiple touches deteriorates
Solution Approach 1:
The patent changes from using a single parameter (touch time period) to using multiple parameters (pressure magnitude, area, and time period) for touch recognition. This allows the system to accurately distinguish between single touches and multiple touches by analyzing the combination of these parameters, thereby improving measurement precision while maintaining ease of operation through automatic multi-parameter analysis.
2Measurement precision
If multiple touch parameters (pressure, area, time) are sensed and analyzed, then the precision of touch recognition is improved, but the device complexity increases
Solution Approach 1:
The patent makes the touch panel serve multiple functions by integrating pressure sensing, area detection, and time period measurement capabilities into a single unified system. This multi-functional approach allows the same hardware infrastructure to collect multiple parameters simultaneously, improving touch recognition precision without proportionally increasing device complexity.
Solution Approach 2:
The patent combines the sensing of pressure magnitude, touch area, and time period into a unified touch recognition process. By merging these parameter detections and analyzing them together to distinguish single touches from multiple touches, the system achieves high recognition precision while avoiding the complexity of separate independent systems for each parameter.
3Measurement precision
If touch intensity and area variations are considered, then the accuracy of touch input interpretation is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent detects touch intensity by measuring pressure magnitude and determines touch area through area sensing capabilities. By converting these physical variations into measurable electrical parameters and analyzing their changes over time, the system achieves accurate touch input interpretation while managing the detection complexity through standardized measurement approaches.
