Vehicle Display Touch Area Compensation for Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, the limited size of display screens and the motion-induced inertial forces make it difficult for drivers to accurately input touches on GUIs, leading to unintended application executions, which can distract the driver and potentially cause accidents.
Innovation Solution
A display device for vehicles that adjusts the touch area of a GUI based on the vehicle's motion and user habits, using a processor to determine the touch displacement and correct it according to inertial forces and user input, ensuring accurate touch inputs even during vehicle motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display size is increased to improve touch accuracy, then the touch input accuracy is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent changes the parameters of the touch area by dynamically adjusting its position and size based on vehicle motion data. The processor receives acceleration data from sensors, calculates compensation values, and modifies the touch area parameters accordingly, allowing accurate touch input without increasing physical display size
Solution Approach 2:
The patent replaces the mechanical approach of increasing physical display size with a software-based compensation system. Instead of mechanically enlarging the display, the system uses sensor data and software algorithms to virtually adjust the touch area, substituting physical expansion with computational correction
2Measurement precision
If the display size is increased to improve touch accuracy, then the touch input accuracy is improved, but the installation space requirements increase
Solution Approach 1:
The system dynamically changes the touch area parameters (position and size) based on vehicle motion rather than increasing the physical display area. This allows the same physical space to provide accurate touch input under varying motion conditions
3Device complexity
If the touch area is fixed to simplify the system, then the device complexity is reduced, but the touch input accuracy deteriorates during vehicle motion
Solution Approach 1:
The patent makes the touch area dynamic by allowing its position and size to change in real-time based on vehicle motion data. The processor continuously updates the touch area parameters in response to acceleration sensor data, transforming a static touch area into an adaptive one that compensates for motion effects
Solution Approach 2:
The system implements feedback by using acceleration sensors to detect vehicle motion, processing this data to calculate compensation values, and applying these corrections to the touch area. This closed-loop feedback mechanism maintains touch accuracy without requiring complex manual adjustments
