Touch Display Gesture Detection Noise Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-sensitive displays in portable electronic devices face challenges in accurately detecting both touch inputs and three-dimensional gestures, especially when these gestures are performed by objects spaced away from the device, due to interference from transmitters during touch detection.
Innovation Solution
The electronic device employs transmitters and receivers to perform 3D gesture detection when no touch is detected, discontinuing 3D gesture detection upon detecting a touch to reduce noise and enhance touch detection accuracy, utilizing a method that prioritizes touch detection over 3D gesture detection to improve input recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmitters and receivers are used for 3D gesture detection, then 3D gesture recognition capability is improved, but noise interference during touch detection increases
Solution Approach 1:
The system dynamically switches between touch detection mode and 3D gesture detection mode based on operational conditions. During touch detection, 3D gesture detection is suspended to eliminate noise interference. When touch detection is complete, the system transitions to 3D gesture detection mode, enabling versatile input recognition without compromising touch accuracy.
Solution Approach 2:
The system employs periodic alternation between touch detection and 3D gesture detection operations. By cycling between these two detection modes, the system ensures that transmitters and receivers are activated only when needed for 3D gestures, while touch detection proceeds with minimal interference, thus maintaining both capabilities over time.
2Measurement precision
If touch detection is prioritized over 3D gesture detection, then touch detection accuracy is improved, but 3D gesture detection responsiveness deteriorates
Solution Approach 1:
The detection priority is dynamically adjusted based on the current operational state. When a touch event is detected, the system immediately prioritizes touch detection to ensure high accuracy. Once touch detection is complete or no touch is present, the system dynamically switches to prioritize 3D gesture detection, ensuring responsive gesture recognition without compromising touch accuracy when needed.
