Motion Compensation for Touch Screen Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with display and touch screens face user interface challenges due to screen instability caused by environmental vibrations or user unsteadiness, making it difficult to view and interact with the screen effectively.
Innovation Solution
The method involves compensating for motion by adjusting the display screen and touch screen input regions using motion and touch data, such as scaling images and varying input regions, to maintain a stable user interface despite device or selection object movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display screen is made larger to improve visibility, then the viewing area increases, but the screen becomes more unstable in vibrating environments
Solution Approach 1:
The patent applies dynamics by making the display screen and touch screen adjustable and reconfigurable in real-time. The system dynamically changes the display parameters, touch sensitivity zones, and interface element positions based on detected motion and vibration conditions, allowing the screen to adapt its characteristics rather than remaining static and vulnerable to instability
2Measurement precision
If the touch screen input regions are made smaller to increase precision, then the selection accuracy improves, but the touch targets become harder to hit when the device is moving
Solution Approach 1:
The system dynamically adjusts touch screen input regions based on detected motion. When vibration or movement is detected, the input regions expand or shift to compensate for the instability, making them easier to hit. When the device is stable, the input regions return to their normal precise sizes, maintaining selection accuracy
Solution Approach 2:
The patent changes the parameters of the touch screen input regions (size, position, sensitivity) based on motion detection data. This allows the system to optimize between precision and ease of operation by adjusting parameters in real-time according to the environmental conditions
3Quantity of substance
If the display elements are made closer together to show more information, then the information density increases, but the elements become indistinguishable when the screen vibrates
Solution Approach 1:
The display dynamically adjusts the spacing and positioning of visual elements based on vibration detection. When motion is detected, the system increases spacing between elements or stabilizes their positions to maintain distinguishability. When stable, elements can be placed closer together to maximize information density
